TWM513738U - Finisher nozzle and finisher assembly including the same - Google Patents

Abstract

A polymer finisher assembly having a finisher nozzle includes a vessel including an outlet orifice and an inlet orifice. The finisher nozzle extends through the inlet orifice of the vessel. The finisher nozzle includes an isometric barrel extending between a nozzle inlet port and a nozzle outlet port. A separator helix is within the isometric barrel. The separator helix separates a mixed flow of steam and polymer fluid and directs steam toward a barrel inner perimeter and directs the polymer fluid separated from the steam toward a helix axis and the nozzle outlet port. The isometric barrel and the separator helix cooperate to confine spattering of polymer fluid separated from steam to the melt pool and isolate an inner vessel wall of the vessel from spattering.

Description

Dresser nozzle and trimmer assembly including the same

The present invention relates to a finisher nozzle and a polymer trimmer assembly including the trimmer nozzle.

Commercial preparation of linear polycondensates typically involves heating the monomer starting material to cause gradual condensation of the polymer. In one example, the process is carried out in several stages, with the removal of volatiles (eg, in a flasher) to immediately form a low molecular weight, low viscosity polymeric fluid. The low molecular weight, low viscosity polymeric fluid then passes through a conditioning zone controlled at various vacuum and residence times and temperatures to allow the polymer to achieve the desired final molecular weight and viscosity.

Polymers having RVs that are considerably higher than the relative viscosity (RV) that can be achieved by equilibrium with steam at atmospheric pressure may be desirable. The high RV polymer is prepared by subjecting the polymer fluid to a reduced partial pressure of steam in the trim zone. The partial pressure of the reduced steam is achieved by using an inert atmosphere or partial vacuum trimming. Since the polymer melt from the flasher (eg, polymer fluid) contains a significant amount of moisture (eg, steam), the inert gas consumption or equipment necessary to maintain an extended portion of the vacuum is trimmed to be greater than steam. A relatively high viscosity (e.g., 50 percent) that balances the achieved viscosity is expensive and labor intensive. The increased time necessary to produce a high viscosity polymer from the vapor-mixed stream of vapor from the flasher to the polymer fluid results in gelation Or a further degraded polymer.

In some examples, one or more trimmer nozzles having a wedge configuration are used to deliver a mixed flow of polymer fluid and steam from the flasher to the conditioner vessel. The dresser nozzle includes a wedge that tapers as the nozzle approaches the dresser container. A spiral separator is provided in the nozzle as appropriate. The spiral separator separates the vapor from the polymer fluid, and the wedge shape of the dresser nozzle slows the vapor before it enters the dresser vessel to reduce the carryover of the polymer fluid with steam and atomization. Thus, the wedge nozzle is intended to cooperate with the separation of the vapor and polymer fluid to reduce the splash of polymer fluid above the pool line of the melt pool along the vessel wall (eg, otherwise carried away with steam or delivered to the melt pool at high velocity) Internal to cause splashing). In practice, with the trimmer nozzles of this configuration, the polymer fluid continues to splash at a bad level along the walls of the vessel. The splashed polymer fluid gels over time and the gel can break from the vessel wall and one or more of the front degranifier or fiber spin system. Loose gelled polymers can cause one or more of the blocked or low quality polymer products.

The creators have in particular recognized that the problem to be solved may include reducing the appearance of the polymer gel along the wall of the dresser vessel. In one example, the subject matter can provide a solution to this problem, such as by providing a volumetric bucket having a substantially constant inner circumference and inner area of the barrel and a dresser provided in the separator coil therein. nozzle. The equal volume bucket directs the separated polymer and vapor stream downwardly toward the melt pool of the conditioner vessel and substantially reduces the radial or lateral velocity components of the vapor and polymer. Thus, the inner vessel wall is substantially isolated from splashing caused by the lateral movement of the polymer fluid or the vapor containing the entrained polymer fluid.

In addition, the present inventors have recognized in particular that the problem to be solved may include reducing the splash of the separated polymer fluid with the separated vapor and the re-taking of the polymer along the wall of the dresser vessel. In another example, the subject matter can provide a solution to this problem. For example, by providing a dresser nozzle having an equal capacity barrel and a separator coil that is separated from the inner circumference of the barrel by a separator gap. The substantially constant inner perimeter and inner area of the barrel maintains or increases the velocity of the mixed flow of polymer fluid and steam within the dresser nozzle. For example, as the mixed stream flows over the helical section of the separator coil, when the polymer fluid remains along the axis of the coil (eg, at the center of the nozzle), the lower density vapor separates and faces the zone The separator gap between the outer edge of the segment and the inner circumference of the barrel moves. The equal volume bucket cooperates with the spaced apart helical sections (eg, anchored and separated by discrete section anchors) to maintain the velocity of the steam, and thus is maintained within the separator gap near the circumference of the barrel. steam. The polymer fluid flowing along the axis of the spiral is thus isolated from the separated vapors and substantially prevented from being carried away with the separated steam.

1 is a schematic illustration of one example of a continuous polymerization system 100. As shown in Figure 1, even The continuous polymerization system 100 comprises a polymer configured to polymerize and gradually produce a higher molecular weight (higher relative viscosity) polymer (eg, polyamine, such as a lipid having at least 85 percent aliphatic chain between repeating amine units) A series of components of a polyamine (for example, nylon). Polyamine can be any suitable polyamine, such as nylon 6, nylon 7, nylon 11, nylon 12, nylon 6,6, nylon 6,9, nylon 6,10, nylon 6, 12 or a copolymer thereof.

The continuous polymerization system 100 is configured to produce a polyamine by continuously passing an aqueous solution of a diamine-dicarboxylic acid salt through a continuous reaction under superatmospheric pressure. The diamine-dicarboxylic acid salt solution provided from the salt supply reservoir 102 is passed through at least one component (eg, reactor, flasher, conditioner, or the like) at an amine formation temperature. A reaction zone 104. The rate of travel of the salt solution via each component is such that a substantial portion of the salt is converted to polyamine. The polyamine reaction composition then passes through at least one additional component of the reaction zone while still at the amine forming temperature and under pressure to allow vapor formation. In this additional component, water is gradually removed from the reaction composition as steam. Finally, the composition comprises molten polyamine and the pressure is substantially atmospheric while the continuous polymer vapor exits the reaction zone. As shown in Figure 1, continuous polymer vapor is delivered to one or more end point assemblies, including, for example, a fiber spinner or granulator (shown as assembly 106) that spins the polymer into the fiber, respectively Or the polymer is formed in the aggregated particles.

In one example, the reaction zone 104 has an evaporator 108 in front of it. The evaporator 108 adjusts the concentration of the salt solution provided from the salt supply reservoir 102 (via removal of water) prior to polymerization in the reaction zone 104.

Returning to the discussion of reaction zone 104 as shown in FIG. 1, the reaction zone contains a reactor 110. The salt solution is delivered to reactor 110 and conditions (e.g., temperature and pressure) within the reactor are maintained to convert a major portion of the salt to the polymer and prevent vapor formation. As further shown in FIG. 1, a flasher 112 is provided downstream of the reactor 110. In flasher 112, the amide temperature is maintained by progressive pressure reduction. The reduced pressure permits separation of water as a vapor from the reaction mass (eg, water and polymer). Polymer and steam The mixed stream is continuously fed to the heated dresser 114 where the polymerization is completed to the desired extent. The degree of polymerization is indirectly expressed as the viscosity of the polymer as measured by relative viscosity or RV. The viscosity is controlled during the finishing step. At high temperatures, the degree of polymerization varies with the amount of water present and is limited by the amount of water. Thus, as water is removed from the polymer fluid as vapor by the trimmer 114, the RV increases (eg, the degree of polymerization increases).

Polyamines having an RV that is considerably higher than the RV achievable by equilibrium with steam at atmospheric pressure are desirable. The high RV polymer is prepared by subjecting the mixture of polymer and water to a reduced partial pressure of steam in the trimmer 114 (e.g., the dresser assembly). The reduced partial pressure of steam is achieved during the trimming process by using an inert atmosphere or by trimming under partial vacuum (in one example, supplied by a vent condenser). Trimming may require significant residence time within the trimmer 114. A problem with trimming is that the increased time necessary to produce a high viscosity polymer (from a vapor-filled mixture of polymer and water) in the dresser 114 can result in a gelled or otherwise degraded polymer. For example, the gel is formed along one or more portions of the trimmer 114 or formed from a splash along the walls of the container, and as the gel is removed from the dresser, it can block the exit aperture of the trimmer or polymerize the output. The quality of the material is degraded.

The trimmer 114 can have any suitable size. For example, the trimmer can have from about 2 m to 200 m, or from about 4 m to 100 m, or from about 5 m to 50 m, or about 2 m or less, or about 3 m, about 4 m, about 5 m, about 8 m, about 10 m, about 12 m. , about 14 m, about 16 m, about 18 m, about 20 m, about 22 m, about 24 m, about 26 m, about 28 m, about 30 m, about 35 m, about 40 m, about 45 m, about 50 m, about 55 m, about 60 m, about 65 m, about A height of 70 m, about 75 m, about 80 m, about 85 m, about 90 m, about 95 m, about 100 m, about 125 m, about 150 m, about 175 or about 200 m or more. The trimmer can have any suitable diameter. For example, the upper portion of the dresser, which can have walls that are substantially parallel to each other, can have any suitable height, such as from about 1 m to 100 m, or from about 2 m to 50 m, or from about 3 m to 25 m, or about 1 m or less, or About 2 m, about 3 m, about 4 m, about 5 m, about 8 m, about 10 m, about 12 m, about 14 m, about 16 m, about 18 m, about 20 m, about 22 m, About 24 m, about 26 m, about 28 m, about 30 m, about 35 m, about 40 m, about 45 m, about 50 m, about 55 m, about 60 m, about 65 m, about 70 m, about 75 m, about 80 m, about 85 m, about 90 m, about 95 m Or a height of about 100 m or more, and may have any suitable diameter, such as about 1 m to 50 m, or about 2 m to 25 m, or about 3 m to 15 m, or about 1 m or less, or about 2 m, about 3 m, about 4m, about 5m, about 8m, about 10m, about 12m, about 14m, about 16m, about 18m, about 20m, about 22m, about 24m, about 26m, about 28m, about 30m, about 35m, about 40m, about 45m or A diameter of about 50 m or more (for example, an inner diameter or an outer diameter).

2 shows an example of a trimmer assembly 200 (eg, used as the trimmer 114 in FIG. 1). As shown, the trimmer assembly 200 includes a trimmer nozzle 202 positioned within the trimmer container 204. For example, the trimmer nozzle 202 as shown in FIG. 2 has a substantially constant perimeter extending from the inlet aperture 206 of the trimmer container 204 and into the interior of the conditioner receptacle 204 (if circular, substantially Constant circumference or diameter) or area. The term "substantially" as used herein refers to most or a plurality, such as at least about 50%, about 60%, about 70%, about 80%, about 90%, about 95%, about 96%, about 97%, About 98%, about 99%, about 99.5%, about 99.9%, about 99.99%, or at least about 99.999% or more. The diameter or area of the nozzle 202 at the inlet near the inlet aperture 206 may be the same as the diameter or area of the nozzle 202 at the outlet that allows the polymer fluid 228 to enter the interior of the conditioner vessel 204. The walls of the nozzles 202 may be parallel to each other (such as the entire length of the wall from the inlet to the outlet of the nozzle 202), or may form from about 0 degrees to about 10 degrees, from 0 degrees to about 10 degrees, from 0 degrees to about 5.5 degrees with respect to each other. 0 degrees to about 2.5 degrees, 0 degrees to about 1.5 degrees or about 0 degrees, about 0.5 degrees, about 1 degree, about 1.5 degrees, about 2 degrees, about 2.5 degrees, about 3 degrees, about 3.5 degrees, about about 0.5 degrees to each other. 4 degrees, about 4.5 degrees, about 5 degrees, about 5.5 degrees, about 6 degrees, about 6.5 degrees, about 7 degrees, about 7.5 degrees, about 8 degrees, about 8.5 degrees, about 9 degrees, about 9.5 degrees, about 10 degrees An angle of about 10.5 degrees, about 11 degrees, about 11.5 degrees, about 12 degrees, about 14 degrees, about 16 degrees, about 18 degrees, or about 20 degrees. As will be described herein, the trimmer nozzle 202 depicted and described in FIG. 2 separates the previously processed polymer-steam (eg, water) mixed stream from the reaction zone 104 of the continuous polymerization system 100. The trimmer nozzle 202 separates the vapor from the polymer and delivers the separated steam 230 and polymer fluid 228 to the conditioner vessel 204, for example, to the melt pool 224. Dresser nozzle 202 will The separated polymer fluid 228 is delivered to the melt pool 224 and the splash of the separated polymer fluid is confined to the melt pool 224. In other words, the inner vessel wall 229 of the isolator vessel 204 is isolated in accordance with the equal volume bucket of the trimmer nozzle 202 (e.g., having a substantially constant inner circumference of the barrel and a substantially constant inner area) in cooperation with the separator auger described herein. To avoid splashing of the separated polymer fluid 228 (and the separated steam 230).

The dresser nozzle can have any suitable length. For example, the trimmer nozzle can have from about 0.5 m to about 20 m, or from about 1 m to about 10 m, about 0.5 m or less, or about 1 m, about 1.5 m, about 2 m, about 2.5 m, about 3 m, about 3.5. m, about 4 m, about 4.5 m, about 5 m, about 5.5 m, about 6 m, about 6.5 m, about 7 m, about 7.5 m, about 8 m, about 8.5 m, about 9 m, about 9.5 m, about 10 m, about 11 m, A length of about 12 m, about 13 m, about 14 m, about 15 m, about 16 m, about 17 m, about 18 m, about 19 m, or about 20 m. The trimmer nozzle can have any suitable inlet diameter, such as from about 0.01 m to about 3 m, or from about 0.1 m to about 2 m, or about 0.01 m or less, or about 0.05 m, about 0.1 m, about 0.2 m, about 0.3m, about 0.4m, about 0.5m, about 0.6m, about 0.7m, about 0.8m, about 0.9m, about 1m, about 1.1m, about 1.2m, about 1.3m, about 1.4m, about 1.5m, About 1.6 m, about 1.7 m, about 1.8 m, about 1.9 m, about 2 m, about 2.1 m, about 2.2 m, about 2.3 m, about 2.4 m, about 2.5 m, about 2.6 m, about 2.7 m, about 2.8 m , about 2.9m or about 3m or more. The dresser nozzle can have any suitable exit port diameter, such as from about 0.01 m to about 3 m, or from about 0.1 m to about 2 m, or about 0.01 m or less, or about 0.05 m, about 0.1 m, about 0.2 m, About 0.3 m, about 0.4 m, about 0.5 m, about 0.6 m, about 0.7 m, about 0.8 m, about 0.9 m, about 1 m, about 1.1 m, about 1.2 m, about 1.3 m, about 1.4 m, about 1.5 m. , about 1.6 m, about 1.7 m, about 1.8 m, about 1.9 m, about 2 m, about 2.1 m, about 2.2 m, about 2.3 m, about 2.4 m, about 2.5 m, about 2.6 m, about 2.7 m, about 2.8 m, about 2.9 m or about 3 m or more.

As further shown in FIG. 2, the trimmer assembly 200 includes a heat exchanger envelope 227 positioned about the conditioner vessel 204. In an example, the heat exchanger envelope 227 is operated to heat The polymer fluid (e.g., the polymer fluid contained within the melt pool 224) facilitates removal of water in the form of steam by the vent condenser 226. In one example, heat exchanger envelope 227 is sized and shaped to accommodate the flow of heated fluid therein. In one example, the heating fluid includes, but is not limited to, a solution of diphenyl-diphenyl oxide provided as a vapor in the heat exchanger envelope 227 adjacent to the conditioner vessel 204. As further shown in FIG. 2, the trimmer assembly 200 includes a barrel 213 (eg, a barrel at the exit aperture 208). The barrel 213 and the polymer fluid delivered therethrough are optionally heated by a heat exchanger envelope 227. In one example, the heat exchanger envelope 227 associated with the barrel 213 is a separate envelope configured to provide a flow of liquid heating fluid therein. The liquid heating fluid includes, but is not limited to, diphenyl-diphenyl oxide in liquid form.

Referring again to FIG. 2, the trimmer assembly 200 includes an exit aperture 208 at the opening of the barrel 213. The exit aperture 208 is sized and shaped to deliver a polymer fluid therethrough (eg, to one or more end point assemblies 106, such as the fiber spinner or granulator shown in FIG. 1). In one example, the exit aperture 208 and barrel 213 include a screw pump 210 having a screw 212 therein. The screw 212 of the screw pump 210 is rotated to deliver the polymer fluid from the finisher vessel 204 to one or more end point assemblies 106 in a measured manner. In another example, a downstream pump, such as a positive displacement gear pump, is inserted between the dresser assembly 200 and the end point assembly 106. The downstream pump draws the polymer fluid delivered by the self-dressing assembly 200 to one or more of these components 106.

Referring again to FIG. 2, in one example, the trimmer assembly 200 includes an agitator 214. As shown, the agitator 214 is coupled to the screw 212 of the screw pump 210. Accordingly, rotation of the screw 212 is transmitted to the agitator 214 to agitate (mix and wipe, as described herein) the polymer fluid 228 within the melt pool 224. Stirring provided by agitator 214 consistently mixes the polymer within melt pool 224, distributes heat from heat exchanger envelope 227, and retards gel production within melt pool 224. As shown in the example, the agitator 214 includes a spiral band 216 that extends from the vicinity of the exit aperture 208 toward the surface of the beach line or the upper portion of the melt pool 224. Stretch. The spiral band 216 includes abutment against the inner vessel wall 229 (e.g., within about 1.3 cm of the wall, or within about 0.6 cm of the wall, such as within about 0.0001 cm to about 1.3 cm or about 0.6 cm of the wall, such as , about 0.0001 cm or less from the wall, or about 0.0005 cm, about 0.001 cm, about 0.005 cm, about 0.01 cm, about 0.05 cm, about 0.1 cm, about 0.2 cm, about 0.3 cm, about 0.4 cm from the wall. An outer perimeter (eg, an outer edge) of about 0.5 cm, about 0.6 cm, about 0.7 cm, about 0.8 cm, about 0.9 cm, about 1 cm, about 1.1 cm, about 1.2 cm, or about 1.3 cm or more. The spiral band 216 thus wipes the polymer fluid from along the inner vessel wall 229 and prevents or reduces stagnation along the innermer wall. The gel formation along the inner vessel wall 229 adjacent the spiral strip 216 is thereby substantially reduced.

In one example, the agitator 214 includes one or more mixing struts 218 positioned inwardly relative to the spiral band 216 (eg, the spacing between the mixing struts 218 and the inner vessel wall 229 includes, but is not limited to, 5 cm or less, Or about 6 cm, about 7 cm, about 8 cm, about 9 cm, about 10 cm, about 11 cm, about 12 cm, about 13 cm, about 14 cm, about 15 cm, about 16 cm, about 17 cm, about 18 cm, about 19 cm, or about 20 cm or more, and Depending on the case, it corresponds to the width of the spiral band 216). The plurality of mixing struts 218 include, for example, wedge-shaped struts that extend from the exit aperture 208 to the agitator ring 220. The mixing struts 218 mix the polymer fluid within the inner portion of the melt pool 224 (e.g., away from the inner vessel wall 229 relative to the spiral ribbon 216). In other words, the mixing struts 218 are positioned away from the inner vessel wall 229, and the mixing of the polymer fluid within the interior of the melt pool 224 is primarily by the mixing struts 218 (and one or more optional diagonals also shown in Figure 2) The struts 219) are provided while the wiping of the polymer fluid along the inner vessel wall 229 is performed by the spiral strips 216.

As further shown in FIG. 2, in one example, the agitator 214 includes one or more baffles 222. The partition 222 is perforated to allow polymer fluid to flow therethrough, for example, toward the exit aperture 208. In another example, the baffle 222 includes an upper baffle and a lower baffle (the lower baffle is at least partially hidden by the agitator ring 220 shown in Figure 2), the upper baffle and the lower baffle providing respectively a polymer fluid Move down and up so as to hang inside the dresser container 204 Mix the polymer fluid straight.

Various features of the agitator 214 (eg, mixing strut 218, spiral band 216, and baffle 222) cooperate to mix and thereby reduce and prevent gradual removal of water (in the form of steam) (eg, by venting a condenser) 226) stagnation of the polymer fluid within the dresser vessel 204 to promote an increase in the molecular weight of the polymer. The agitator 214 can have any suitable height. For example, the agitator can have from about 1 m to 30 m, or from about 2 m to about 15 m, or about 1 m or less, or about 1 m, about 2 m, about 3 m, about 4 m, about 5 m, about 6 m, about 7 m, about 8m, about 9m, about 10m, about 11m, about 12m, about 13m, about 14m, about 15m, about 16m, about 18m, about 20m, about 22m, about 24m, about 26m, about 28m or about 30m or more height. The agitator 214 can have any suitable uppermost diameter, such as from about 1 m to 50 m, or from about 2 m to about 25 m, or from about 3 m to about 15 m, or about 1 m or less, or about 2 m, about 3 m, about 4 m, About 5 m, about 8 m, about 10 m, about 12 m, about 14 m, about 16 m, about 18 m, about 20 m, about 22 m, about 24 m, about 26 m, about 28 m, about 30 m, about 35 m, about 40 m, about 45 m or about 50 m Or larger diameter. The agitator 214 can have any suitable lowermost diameter, such as from about 0.001 m to about 50 m, or from about 0.01 m to about 25 m, or from about 0.1 m to about 15 m, or from about 0.001 m or less, or about 0.01 m, About 0.1 m, about 0.2 m, about 0.4 m, about 0.6 m, about 0.8 m, about 1 m, about 1.5 m, about 2 m, about 2.5 m, about 3 m, about 3.5 m, about 4 m, about 4.5 m, about 5 m About 6 m, about 7 m, about 8 m, about 9 m, about 10 m, about 15 m, about 20 m, about 25 m, about 30 m, about 35 m, about 40 m, about 45 m or about 50 m or more.

Referring again to the agitator 214 shown in FIG. 2, in one example, the agitator 214 includes an agitator ring 220. As shown, the agitator ring 220 is coupled to one or more of the mixing strut 218 or the spiral strap 216. The spiral band 216 can comprise abutment against the inner vessel wall 229 (eg, within about 1.3 cm of the wall, or within about 0.6 cm of the wall, such as within about 0.0001 cm to about 1.3 cm or about 0.6 cm of the wall, For example, about 0.0001 cm or less from the wall, or about 0.0005 cm, about 0.001 cm, about 0.005 cm, about 0.01 cm, about 0.05 cm from the wall, about 0.1 cm, about 0.2 cm, about 0.3 cm, about 0.4 cm, about 0.5 cm, about 0.6 cm, about 0.7 cm, about 0.8 cm, about 0.9 cm, about 1 cm, about 1.1 cm, about 1.2 cm or about 1.3 cm or One of the larger outer perimeters (for example, the outer edge). The agitator ring 220 provides support for one or more of the mixing strut 218, the spiral band 216, and the baffle 222, and thus maintains such components in the configuration shown. Additionally, the agitator ring 220 mixes the polymer fluid as appropriate. In one example, the agitator ring 220 includes one or more grooves, recesses, blades, or the like along the surface of the ring (eg, one or more of the inner or outer surface) to enhance the agitator 214 provides a mix.

In the example shown, the agitator ring 220 is positioned remotely relative to the inner vessel wall 229 (eg, in close proximity to the outer edge of the spiral ribbon 216). In other words, a spacing is provided between the agitator ring 220 and the wall 229 relative to the close proximity of the outer edge of the spiral band 216 to the wall 229. Optionally, the distance between the agitator ring 220 and the inner vessel wall 229 includes, but is not limited to, 5 cm or less, or about 6 cm, about 7 cm, about 8 cm, about 9 cm, about 10 cm, about 11 cm, about 12 cm, about 13 cm, About 14 cm, about 15 cm, about 16 cm, about 17 cm, about 18 cm, about 19 cm, or about 20 cm or more, and optionally, the width of the spiral strip 216. Thus, as the agitator 214 rotates within the dresser assembly 200, for example, by rotation within the melt pool 224, the agitator ring 220 and the inner vessel wall 229 and along the inner vessel wall 229 (eg, with agitation) The gel ring 220 is opposed to the formed gel. By moving the agitator ring 220 inwardly, for example, by separating it from the inner vessel wall 229, even in the case of forming a gel along the inner vessel wall 229, the agitator ring 220 is condensed relative to the condensation The glue is positioned at a distance and any mechanical bond between the ring and the gel is substantially reduced. Therefore, the removal of the gel via binding is similarly reduced.

In a similar manner, and as described herein, the mixing strut 218 is positioned remote from the inner vessel wall 229. In other words, a spacing is provided between the mixing strut 218 and the inner vessel wall 229 relative to the close proximity of the outer edge of the spiral strip 216 to the inner vessel wall 229. For example, the distance between the mixing strut 218 and the inner vessel wall 229 includes, but is not limited to, 5 cm or more. Small, or about 6 cm, about 7 cm, about 8 cm, about 9 cm, about 10 cm, about 11 cm, about 12 cm, about 13 cm, about 14 cm, about 15 cm, about 16 cm, about 17 cm, about 18 cm, about 19 cm, or about 20 cm or more And, as the case may be, corresponds to the width of the spiral strip 216. Where the polymer gel is formed along one or more of the mixing struts 218, the gel system is positioned remote from the inner vessel wall 229. Thus, the gel on the mixing strut 218 will not bond with the container wall 229 and will similarly not be removed. That is, even with the finisher assembly 200 producing a gel along the inner vessel wall 229, by including the agitator 214 (having a remotely positioned agitator ring 220 and mixing struts 218) as shown in FIG. The dresser assembly 200 substantially still prevents any mechanical bond that is otherwise provided by the agitator ring 220 (or mixing strut 218) that is positioned at least slightly against the inner vessel wall 229. The remotely located agitator ring 220 does not remove the gel from the inner vessel wall 229, and during operation of the trimmer assembly 200 (eg, during an extended period of time such as 91 days or longer), the inner vessel wall 229 Accordingly, the gel is not bonded and removed from the gel formed along the agitator ring 220 or the mixing strut 218.

As previously described herein, the creation of a gel within the dresser assembly 200 can cause occlusion and produce a lower grade polymer when the gel is removed. In the configuration shown in FIG. 2, by combining one or more of the mixing struts 218 and the agitator ring 220 spaced from the inner vessel wall 229, the bonding and migration of the formed polymer gel is substantially reduced. go. The dresser assembly 200 including the agitator 214 is configured to operate over a substantially extended period (91 days or more) and promotes the production of high quality (high molecular weight) polymers over time. Without blocking.

As further shown in FIG. 2, in one example, the vent condenser 226 is coupled by an elbow to the trimmer vessel 204, which extends to a vent condenser 226 at the end of the elbow. In one example, the vent condenser 226 includes a vacuum injection or vacuum generation system configured to draw over an atmosphere within the conditioner vessel 204, such as an atmosphere in which it is humidified (filled with steam). In another example, steam is supplied to a vent condenser 226 (eg, at a desired water content) to thereby adjust the atmosphere of the self-dresser vessel 204 via a vent condenser 226 The amount of water drawn (eg, separated steam 230). For example, a "kill" or supplemental steam stream is fed to the vent condenser 226 via a supplemental steam line. The supplemental steam is reduced or increased to thereby withdraw more or less steam with respect to the separated steam 230 within the conditioner vessel 204, respectively. In other words, by reducing the supplemental steam to the vent condenser 226, a relatively dry air flow at a negative pressure is created, which thus withdraws additional steam from the dresser vessel 204. Conversely, by adding supplemental steam to the vent condenser 226, a humidified air stream is produced that withdraws very little steam from the dresser vessel 206. The amount of separated steam 230 withdrawn from the finisher vessel 204 is controlled by adjustment to the injection of supplemental steam within the vent condenser 226. Thus, the quality (e.g., the molecular weight of the separated polymer fluid 228) is correspondingly controlled.

Additionally, the vent condenser 226 includes a condensing system that includes a weir, for example, a convex ridge provided on the interior periphery of the vent condenser. The crucible is filled with a side of the submerged crucible and flows into the cooling water stream in the remainder of the vent condenser 226. The cooling water stream (having a lower temperature relative to the separated steam 230) thus condenses water from the separated steam 230 and removes moisture from the dresser vessel 204. Removal of moisture allows the separated polymer fluid 228 to increase its molecular weight, with continued polymerization corresponding to an increase in the relative viscosity of the polymer. In another example, one or more water sprays are provided across the vent condenser 226 (eg, across the crucible) to further promote condensation of steam from the atmosphere within the conditioner vessel 204.

FIG. 3 illustrates the trimmer nozzle 202, which is another component of the trimmer assembly 200. In FIG. 2, the trimmer nozzle 202 is shown extending into the dresser container 204. 3 is a partial cross section of the dresser nozzle 202. The nozzle barrel 303 is cut along its middle and the separator coil 306 is shown in side view. The cylindrical barrel 303 extends from the inlet aperture 300 to the outlet aperture 302. The tub 303 has a barrel inner circumference 304 that surrounds the lumen extending therethrough. As shown in FIG. 3, the tub 303 has a substantially constant inner area 307 between the inlet aperture 300 and the outlet aperture 302 (the cross-sectional area of the barrel measured perpendicular to the helical tube axis 308). That is, the tub 303 is substantially equal in capacity between the inlet aperture 300 and the exit aperture 302. In one example, a portion of the trimmer nozzle 202 (eg, adjacent the exit aperture 302 or adjacent the inlet aperture 300) is used in accordance with FIG. 2 The design of the particular dresser nozzle used in the dresser assembly 200 shown may have a short wedge perimeter, such as a short wedge section having a diameter that monotonically changes over the length of the minor axis. As shown in FIG. 3, the inner circumference 304 and the inner area 307 of the barrel are substantially constant over the length of the separator coil 306 corresponding to that described further herein.

As will be described herein, an equal volume bucket 303 (eg, having a substantially constant barrel inner circumference 304 and a substantially constant inner area 307) cooperates with a separator coil 306 (shown herein) to separate polymer fluids from steam. The mixed stream and thus the separated polymer fluid 228 and separated steam 230 are delivered to the conditioner vessel 204. The trimmer nozzle 202 substantially prevents re-taking of the polymer with the separated vapor 230 to thereby substantially prevent splashing of the separated polymer fluid, otherwise along the inner wall of the dresser container 204 shown in FIG. 229 (as described herein) is carried away with the separated vapor.

Referring again to FIG. 3, the separator coil 306 is shown extending through at least a portion of the barrel 303. As shown, the separator coil 306 includes a plurality of helical segments 310 coupled in series end to end as shown. Any suitable number of helical segments 310 can be included in the separator coil 306. In the example shown in FIG. 3, a separator base plate 312 having a substantially straight configuration is coupled to an adjacent helical section 310. The remainder of the helical section 310 that extends toward the exit aperture 302 has a twisted configuration and cooperates to separate the polymer fluid from the vapor to thereby deliver the separated polymer fluid 228 to the conditioner vessel 204. For example, splashing onto the inner container wall 229 is not allowed.

In an example, each of the helical segments 310 includes a first end 314 and a second end 316. Each of the helical segments 310 extends from the first end 314 to the second end 316 in a helical manner (eg, twisted). As described previously, the separator coil 306 and its section 310 are shown in a side view (not cut). Thus, the first end 314 is shown to be substantially perpendicular to the page, while the second end 316 is parallel to the page. The remainder of each of the segments 310 is thus twisted between the ends 314, 316. In the example shown in FIG. 3, each of the helical sections 310 is twisted substantially 90 degrees from the first end 314 to the second end 316. For example, when external As the edge 305 extends from the second end 316 toward the first end 314, the outer edge 305 along the upper portion of the helical section 310 (as shown in FIG. 3) gradually extends into the page. Conversely, as the edge extends from the second end 316 to the first end 314, the outer edge 305 along the lower portion of the helical section 310 (as shown in FIG. 3) gradually extends out of the page.

In another example, adjacent to the helical section 310 (eg, when starting at the inlet aperture 300, the next helical section 310 on the row toward the exit aperture 302) includes adjacent to the previous helical section 310 The second end 316 is out of phase with the first end 314 of approximately 90 degrees. Thus, the separator coil 306 in the example shown in Figure 3 provides a broken (discontinuous) chain of helical segments 310, each helical segment providing a twisted helical surface (eg, in the same direction) The torsional helical surfaces are engaged at their ends at substantially 90 degrees with respect to each other. That is, the second end 316 of the helical section 310 is substantially 90 degrees out of phase with the first end 314 of the previous helical section 310. Optionally, the helical segments 310 are mated to one another by one or more mechanisms including, but not limited to, welding, mechanical interfitting, or the like, as appropriate.

As further shown in FIG. 3, in one example, the separator coil 306 is coupled at one or more segment anchors 318 to thereby enclose the remainder of the separator coil 306 (such as along the circumference) The outer edge 305) of each of the lengths 304 of the extended section 304 is separated from the inner circumference 304 of the barrel. As will be described herein, the separation between each of the helical sections 310 and the inner circumference 304 of the barrel, such as the spacing or separator gap 320, cooperate to provide vapor for separation (such as a map). The separated steam 230 shown in 2) travels in isolation relative to the separated polymer 228 delivered along the helical tube axis 308 (eg, the first portion can flow near the barrel wall and the second portion can be more Flowing in the middle or near the core). In the example shown in FIG. 3, each of the helical sections 310 and the inner circumference 304 of the barrel are separated by a separate section anchor 318 at a second end 316 (or, as appropriate, at the first end 314 or The middle portion of the segment 310 is coupled. The path for the separated steam 230 extends through between the inner perimeter 304 and the outer edge 305 depending on the spacing (or spacing) provided by the segment anchors 318. Separator gap 320.

In one example, the segment anchor 318 is coupled to the barrel inner perimeter 304 via one or more mechanisms including, but not limited to, an interference fit, a mechanical fit, an adhesive, a spot weld, and the like. As shown in FIG. 3, in one example, the segment anchors 318 are provided along a line (eg, a line that runs parallel to the helical tube axis 308 and along the inner circumference 304 of the barrel). Providing section anchors 318 along a line provides for positioning each of the spot weld elements to the section anchors 318 and thus facilitating each of the section anchors 318 and helical sections 310 A ready path that is coupled to the inner circumference 304 of the barrel. As further shown in FIG. 3, in one example, a plate anchor 322 is provided for the separator base plate 312. In the example shown, the plate anchors 322 are substantially co-linear with the segment anchors 318 of each of the helical segments 310. Thus, coupling (eg, welding or mating) of each of the segment anchors 318 to the plate anchors 322 is achieved in a linear fashion, for example, by positioning spot welds extending through either end of the barrel 303. element.

As previously described, in one example, each of the helical segments 310 is coupled to a barrel inner perimeter 304 (eg, to the segment anchor 318), respectively. The segment anchors 318 cooperate to adhere each of the helical segments 310 to the appropriate locations within the bucket 303. Thus, during maintenance of the finisher nozzle 202 (e.g., during removal of the trimmer nozzle 202 for cleaning or for in-line cleaning of the finisher nozzle 202), the heating and cooling of the nozzle 202 including the separator coil 306 is not The separator coil 306 is warped and the plurality of helical sections 310 are maintained in the orientation shown in FIG. That is, the segment anchors 318 (and optionally the plate anchors 322) cooperate to anchor each of the helical segments 310 (and optionally the separator base plate 312) within the barrel 303 . In other words, warping of the separator coil 306 is correspondingly reduced or prevented by anchoring each of the helical segments 310. Instead, each of the helical sections 310 of the separator coil 306 is securely anchored in place. When the separator nozzle 202 containing the separator coil 306 is heated (and cooled later) during cleaning, the separator coil 306 does not warp within the barrel 303. Thereby in the dresser nozzle 202 The configuration of the separator coil 306 (eg, with the separator gap 320) is maintained during the operational life (included during the cleaning operation and after the cleaning operation).

In operation, a mixed stream of polymer fluid and steam is delivered via inlet aperture 300 as shown in FIG. 3 (eg, from a previous portion of continuous polymerization system 100 previously shown in FIG. 1). For example, a mixed stream of polymer fluid and steam is delivered to the schematic conditioner 114 from the flasher 112 shown in FIG. As shown in FIG. 2, the trimmer nozzle 202 delivers a mixed stream of fluid to the conditioner vessel 204 and separates the mixed stream into separated vapor 230 and separated polymer fluid 228 prior to delivery.

Referring again to FIG. 3, a mixed stream of polymer fluid is first delivered into the inlet aperture 300 of the barrel 303 of the finisher nozzle 202. The mixed flow system is delivered along the separator base plate 312 and onto the separator coil 306. Due to the equal volume barrel 303 (eg, substantially constant barrel inner circumference 304 and substantially constant inner area 307), when a mixed stream of polymer and steam is delivered via barrel 303, as the fluid is delivered toward the exit orifice 302, substantially Maintain or increase its speed. Optionally, the inner perimeter 304 (e.g., the diameter of the inner perimeter) is reduced relative to the previous finisher nozzle to further increase shear (and velocity) within the mixed flow of polymer and steam. In one example, the dresser nozzle 202 has an inner diameter of 12.7 cm compared to the 17.9 cm diameter of the previous wedge nozzle.

As the mixing stream moves along the separator coil 306, the mixing stream combines several series of helical sections 310. As previously described, each of the helical segments 310 has a twisted shape (eg, including a 90 degree twist). In yet another example, each of the helical segments 310 is twisted in the same direction (eg, clockwise or counterclockwise). As the mixed flow of polymer fluid flows along each of the helical sections 310 and along each of the helical sections 310, the velocity of the fluid is maintained by the uniform equal capacity shape of the barrel 303. That is, because of the capacity of the barrel 303 and the like (eg, without the enlarged wedge shape from the inlet to the outlet), the speed of the mixed flow delivered into the barrel 303 can be maintained as opposed to the decrease in speed with the enlarged wedge nozzle. Increase. The helical section 310 divides or separates the mixed stream, for example, by The polymer fluid is allowed to travel along the helical tube axis 308 while the lower density steam moves to the outer portion of the helical section 310 and into the separator gap 320 as it is maintained. In contrast, the reduced speed (in the case of a wedge nozzle) can correspondingly reduce the separation provided when steam is directed more slowly toward the inner circumference 304 of the barrel. The higher density polymer fluid 228 maintains a substantially linear flow along the helical tube axis 308 and thereby is separated from the vapor 230. Because each of the helical segments 310 is spaced from the inner perimeter 304 of the barrel (eg, by the segment anchors 318), steam can readily travel along the separator gap 320 and thereby substantially maintain It is separated from the polymer fluid. Thus, when polymer fluid and steam are delivered toward the exit orifice 302, each of the helical sections 310 cooperates with the inner circumference 304 of the (equal capacity bucket 303) to thereby separate the mixed stream into separated Polymer fluid 228 and separated steam 230. At the exit aperture 302 of the trimmer nozzle 202, the polymer fluid is delivered primarily along the helical tube axis 308 and the separated vapor 230 is delivered primarily along the barrel inner perimeter 304 (and directed downwardly parallel to the helical tube axis 308) ) to the finisher container 204 as shown in FIG.

In addition, the separation provided by the separator coil 306 in combination with the equal volume drum 303 (and the separator gap 320 maintained therebetween) directs the separated steam into the separator gap 320, and thus substantially reduces the area along the zone. The polymer fluid traveling in section 310 is then carried back into the steam. In other words, the vapor maintains its velocity by substantially equal volume barrel 303 and is thus directed away from the guided polymer fluid and maintained within the separator gap (and along the inner perimeter 304) ). Thereby the separation of the vapor 230 from the polymer fluid 228 is maintained via the passage in the nozzle 202 and delivery to the dresser vessel 204.

Moreover, with the configuration shown in FIG. 3, when the separated polymer fluid 228 and the separated vapor 230 are directed by the equal volume drum 303 and delivered into the conditioner vessel 204, any splash of the polymer fluid is substantially Constrained to melt pool 224. As discussed above, the inner vessel wall 229 is isolated from splashing of the separated polymer fluid 228. The vapor is less dense than the polymer and tends to disperse toward the inner vessel wall 229 than the polymer. Therefore, by preventing steaming The polymer in the vapor is again carried away to reduce the outward splash towards the inner vessel wall 229. Additionally, the separated steam 230 flows through substantially along the spiral tube axis 308 and toward the melt pool 224. The lateral velocity component of the separated steam moving through the dresser nozzle 202 is reduced by the equal volume barrel 303 (relative to the enlarged nozzle). Thus, splashing of the vapor along the inner vessel wall 229 by the vapor with the re-carrying polymer is substantially reduced. The separated polymer 228 (and separated steam 230) is directed by the trimmer nozzle 202 toward the melt pool 224 (see FIG. 2), and the splash from the dresser nozzle 202 is similarly directed into the melt pool 224.

4 shows a block diagram of a method 400 for using a polymer trimmer assembly (eg, the trimmer assembly 200 shown in FIG. 2 including a trimmer nozzle 202). In describing the method 400, reference is made to one or more components, features, functions, or the like described herein. Reference numerals, components, features, functions, or the like are referred to by way of example. The reference numbers provided are examples only and are not exclusive. For example, features, components, functions, or the like described in the method 400 include, but are not limited to, corresponding numbering of the corresponding features (numbered and unnumbered) described herein, and equivalents thereof.

At step 402, a mixed flow of steam and polymer fluid is directed via a trimmer nozzle 202 having a barrel (eg, a cylindrical barrel) having a substantially constant inner circumference 304 of the barrel. As described herein, in one example, the inner circumference 304 of the barrel is substantially constant between the inlet aperture 300 and the outlet aperture 302 of the barrel 303. At step 404, the mixed stream of vapor and polymer fluid is separated into separated vapor 230 and separated polymer 228 by a separator coil 306 in combination with a substantially constant barrel inner circumference 304. In an example, separating the mixed stream includes delivering the mixed stream along the separator coil 306. When the mixed stream is delivered from the inlet port 300 toward the outlet port 302, a substantially constant barrel inner circumference 304 maintains the velocity of the mixed stream. The steam separates from the mixing stream and moves radially outwardly between each of the helical sections 310 and the inner circumference 304 of the barrel (eg, by separating the helical section 310 from the inner circumference of the barrel) One or more segment anchors 318) are within the separator gap 320. When the speed of the mixed stream is maintained, the steam tends to move to the inner circumference 304 of the barrel (eg, into the separator gap 320), while the mixed stream The remainder (polymer fluid) flows separately along the helical tube axis 308 of the separator coil 306.

The method 400 can include, at step 406, directing the separated polymer fluid 228 into a container, such as the dresser container 204 shown in FIG. The guided separated polymer fluid 228 is included in step 408 to deliver the separated polymer fluid to the melt pool 224 of polymer fluid in the conditioner vessel 204. In another example, directing the separated polymer fluid to the conditioner container 204 includes, at step 410, confining the splash of the separated polymer fluid to melting according to a barrel 303 having a substantially constant inner circumference 304 of the barrel. The pool 224 and isolates the inner vessel wall 229 from splashing. That is, the substantially constant barrel inner circumference 304 directs the separated steam 230 to flow downward toward the melt pool 224, and thus reduces the lateral component of the separated steam 230. Any polymer fluid that is carried away with the separated vapor 230 is thus directed into the melt pool 224 and toward the inner vessel wall 229, as is the case with wedge nozzles. Additionally and as described herein, the substantially constant barrel inner circumference 304 cooperates with the separator coil 306 (including, for example, the separator gap 320) to facilitate separation of the vapor from the polymer and thus the separated polymer fluid 228. There is no re-taking in the separated steam 230 (as shown in Figure 2). The separated polymer fluid 228 is delivered substantially toward the melt pool 224 along a line that coincides with the axis 308 of the spiral tube, having a substantially reduced or minimized lateral component that will additionally separate the separated polymer fluid 228 (or a portion of the polymer fluid) is delivered toward the inner vessel wall 229.

This is followed by several options for method 400. In an example, directing the steam of the mixed stream includes directing steam between, for example, between an outer edge of the separator coil 306 formed by the edge of each of the helical sections 310 and the inner circumference 304 of the barrel. Within the separator gap 320. In another example, the mixed stream is separated into separated vapors 230 by a separator coil 306 in a cylindrical barrel 303 and the separated polymer fluid 228 comprises a plurality of spirals along the separator coil 306. Section 310 directs the mixed stream of polymer fluid. The polymer fluid that directs the mixed stream along the helical section 310 is included along the respective helical sections 310 A plurality of helical sections coupled at a first end 314 and a second end 316 of each of the leads direct the polymer fluid. As previously described herein, in another example, the first end 314 is out of phase with the adjacent second end 316 (eg, 90 degrees out of phase).

In another example, the confined splash and isolated inner vessel wall 229 includes an orientation along a longitudinal axis of the barrel 303 (eg, an axis coincident with the helical tube axis 308 of the separator coil 306) according to a substantially constant barrel inner perimeter 304 The melt pool 224 directs the separated steam 230 and the separated polymer 228 downward. In yet another example, isolating the inner vessel wall 229 from splashing includes reducing a radial (eg, lateral) component of the separated steam 230 that is directed through the dresser nozzle 202 according to the substantially constant barrel inner perimeter 304. That is, by providing a non-wedge bucket (substantially constant barrel inner circumference 304), the separated steam 230 is instead delivered in an outwardly expanded manner, but rather is delivered by a substantially downward component directed toward the melt pool 224. . Thus, any polymer fluid that is carried away with the separated vapor 230 is also directed downward into the melt pool 224.

In another example, method 400 includes agitating polymer fluid 228 by trim mixer 214, as shown in FIG. As shown, the trim blender 214 rotates within the trimmer container 204. In another example, agitating the separated polymer fluid 228 by trimming the agitator 214 includes wiping the polymer fluid by a spiral band 216 in a wiping zone along the inner vessel wall 229. The outer edge of the spiral band is positioned against the inner vessel wall 229 (e.g., within about 0.6 cm or about 0.7 cm). In still another example, agitating the separated polymer fluid 228 by trimming the agitator 214 includes wiping the polymer fluid by a spiral band 216 in a wiping zone along the inner vessel wall 229.

The agitator ring 220 is coupled to one or more mixing struts 218 located remotely from the inner vessel wall 229 with respect to a spiral belt positioned against the inner vessel wall 229. For example, as shown in FIG. 2, the agitator ring 220 and one or more mixing struts 218 are positioned inwardly relative to the inner vessel wall 229 and the spiral ribbon 216. The close proximity of the one or more mixing struts 218 and the agitator ring 220 to the inner vessel wall relative to the spiral belt 216 is spaced from the inner vessel wall. Stirrer ring 220 is coupled to one or more of the spiral strip 216 or one or more mixing struts 218. Stirring the separated polymer fluid 228 by trimming the agitator 214 includes mixing the separated polymer fluid in a mixing zone remote from the inner vessel wall 229 by coupling one or more mixing struts 218 with the spiral ribbon 216.

In yet another example, agitating the separated polymer fluid 228 includes isolating the inner vessel wall 229 from the agitator ring. As described herein, in one example, the agitator ring 220 is positioned remotely relative to the inner vessel wall 229. Thus, when the gel builds up along the inner vessel wall 229 during operation of the trimmer assembly 200, after the period of operation of the trimmer assembly 200 (eg, after nearly 90 or more consecutive operations), agitation The square of the ring 220 interacts with the gel formed along the wall 229. Similarly, any gel that appears along the agitator ring 220 is positioned remotely relative to the inner vessel wall 229. Thus, the interception of the gel along the inner vessel wall 229 by the agitator ring 220 or the interception of the gel on the agitator ring 220 by the inner vessel wall 229 is reduced, the gel removal is reduced, and The corresponding delivery of the gel into the barrel 213 of the dresser assembly 200 is also reduced. By this configuration, the occlusion and low quality polymer product is substantially reduced (e.g., reduced spatter due to the trimmer nozzle 202, and the recessed struts 218 and the agitator ring 220 are recessed from the inner container wall 229), and is significant The operational life of the dresser assembly 200 prior to cleaning is increased.

In still another example, method 400 further includes cleaning trimmer nozzle 202. Cleaning includes a heated finisher nozzle 202 (eg, barrel 303 and separator coil 306). In addition, each of the plurality of helical sections 310 of the separator coil 306 is prevented from being warped by heating (and cooling after heating). Blocking includes anchoring each of the plurality of helical segments 310 to the inner circumference 304 of the barrel. In one example, the plurality of helical segments 310 are respectively coupled by a plurality of respective segment anchors along the inner perimeter 304 of the barrel (eg, by spot welding, mechanical mating, interference fit, or the like). The fixed portion 318 is coupled to the inner circumference 304 of the barrel.

Aqueous mixture. The aqueous salt was transferred to the evaporator at about 105 L/min. The evaporator heats the aqueous salt to between about 125 ° C and 135 ° C (130 ° C) and removes water from the heated aqueous salt to bring the water concentration to about 30% by weight. The evaporated salt mixture was transferred to the reactor at about 75 L/min. The reactor is such that the temperature of the evaporated salt mixture is between about 218 ° C and 250 ° C (235 ° C), thereby allowing the reactor to further remove water from the heated evaporated salt mixture, thereby bringing the water concentration to about 10% by weight and causing the salt Further polymerization. The reacted mixture was transferred to a flasher at about 60 L/min. The flasher heats the reacted mixture to between about 270 ° C and 290 ° C (280 ° C), thereby allowing the flasher to further remove water from the reacted mixture, thereby bringing the water concentration to about 0.5% by weight, and allowing the reacted mixture Further polymerization. The flashed mixture was transferred to a dresser at about 54 L/min. The dresser subjects the polymerization mixture to a vacuum to further remove water such that the water concentration is about 0.1% by weight such that the polyamidamine achieves a suitable final degree of polymerization prior to transferring the trimmed polymerization mixture to the extruder and granulator. range.
