Definitions

  • the invention relates to a separator according to the preamble of claim 1 as from WO 96/34693 is known and a method for three-phase separation with such a separator.
  • Such separators have been known for a long time.
  • the liquid discharges are provided with so-called peeling discs, in which the effect is exploited that the rotational energy of the incoming liquid is converted into a back pressure in the discharge line.
  • peeling discs have proven themselves.
  • a well-known three-phase separator is in Fig. 3 shown. If one or both of the two fluid outlets from the drum are assigned a paring disc and the further outlet is nozzle-like, the result is an area delta LP within which the paring disc permits a displacement of the separation zone in the drum by throttling (see, eg, US Pat WO 86/01436 ).
  • the range of displaceability of the separation zone is still relatively low and it is not readily possible to move the separating zone in operation fast enough about the peeling discs.
  • the shift also does not always lead to stable process conditions, since the variation of the throttling of the peeling disk processes directly affects several parameters of the process.
  • the invention has the object of developing the generic separator such that in a simple manner during operation, a displacement of the separation zone within the drum over a larger radial range is possible, with an improved adjustability of the position of the separation zone should be possible.
  • a method for operating such a separator is also to be proposed.
  • Throttle devices also on the type in operation non-rotating annular discs are known from the field of solid bowl screw centrifuges known per se - so from the DE 102 09 925 A1 or the DE 102 03 652 A1 , However, the drums of these centrifuges are stored in the region of both axial ends and not oscillating like centrifuges. This results in the difference that the drums of the decanter or solid bowl centrifuges rotate about a defined axis, while the Separatortrommeln Perform a certain precession movement, so that it was assumed that the conditions at the drain ring gap are not constant enough to achieve a defined adjustment of the separation zone between light and heavy phase and a shift of the drainage radius of the heavy liquid phase by means of an adjustable throttle plate. This assumption has not been confirmed. Contrary to expectations, stable conditions also occur at the outlet gap of the separator at the throttle disk. Rather, the throttle disc improves process efficiency as well as fine tuning and process stability.
  • the separator is suitable for a wide variety of three-phase separation tasks, in particular crude oil processing, in which the crude oil is clarified by solids and water is separated from the crude oil.
  • the invention also provides a use of a separator according to the invention according to one of the corresponding claims for crude oil treatment in which the crude oil is clarified by solids and water is separated from the crude oil.
  • the invention also provides a process for the three-phase separation and clarification of a product to be processed in at least two liquid phases and a solid phase, wherein the processing of the product takes place in a separator according to one of the corresponding claims directed to this, wherein for adjusting the separation zone once in operation adjusting the radius of the light liquid phase LP by means of the paring disc and then adjusting the heavy liquid phase (HP) and thus the separation zone by means of the throttle device, preferably the annular disc takes place.
  • Fig.1 to 3 each show separator drums 1, which have a vertically oriented axis of rotation at the radius r 0 .
  • the Separatortrommeln 1 are each set to a rotary spindle 2, for example, the type of Fig. 4 driven directly or via a belt (not shown here) or otherwise (eg a gearbox) is.
  • the rotary spindle 2 may be designed conically in its upper peripheral region.
  • the rotary spindle 2 is mounted with at least one or more bearings 3 on one side of the drum - here below the drum - oscillating and therefore describes in operation due to residual unbalance unlike a decanter a new axis adjusts a kind of precession movement around the vertical r 0 ( please refer Fig. 4 in which the inclination angle ⁇ is shown).
  • constructions are also known in which a lower drum is quasi “suspended" on an upper rotary spindle. Again, however, the drum is rotatably mounted oscillating only at one of its ends or subsequent to one of its axial ends.
  • the separator drum 1 has a feed pipe 4 for a product P to be hurled, to which a distributor 5 adjoins, which is provided with at least one or more outlet openings 6, through which incoming centrifugal material (crossed hatching) into the interior of the separator drum 1 and the Rising channel 7 of the plate package can be passed.
  • a feed through the spindle e.g. from below is also possible.
  • the construction is chosen such that the outlet openings 6 below a riser channel 7 in a plate package 8 (outer diameter at reference numeral 8) of conically shaped separating plates 9 are.
  • the plate package 8 of a Sheath plate 17 completed, which has a larger diameter than the plate package.
  • the Emulionsline or dividing line (also called E line) - forms a separation zone between a lighter liquid phase LP (hatching from the left bottom right top) and a heavier liquid phase HP (hatching to the lower right).
  • the lighter liquid phase LP (light phase) is conducted at an inner radius r LP with the aid of a paring disc 10 (also called a gripper) from the drum.
  • a paring disc 10 also called a gripper
  • the paring disc acts like a pump.
  • the peeling disk is downstream of a valve 18 for throttling, for example, outside the separator in its downstream discharge.
  • the heavy liquid phase HP flows around the outer circumference of the disc plate 17 through discharge passage 11 to a liquid outlet 12 at the upper axial end of the drum 1 (radius r HP ).
  • the constructions of the invention Fig. 1 and 2 are different than the construction of the Fig. 3 provided in the region of the liquid outlet 12 with an adjustable throttle device 13, by means of which the cross section is variable at the liquid outlet.
  • this throttle device 13 In order to realize this throttle device 13 structurally in a simple manner, it is proposed according to the type Fig. 2 and 3 to arrange in the axial direction above the liquid outlet 12 outside the drum 1, a kind of annular or throttle plate 19, which is arranged and formed spaced from the at least one liquid outlet opening, wherein the position of the annular disc 19 to the at least one Outlet opening is variable.
  • the disc may have a flat surface or be provided with grooves, for example.
  • the surface of the annular disc is preferably - but not necessarily - aligned perpendicular to the drum axis.
  • the annular disc 19 is e.g. axially displaceable or arranged pivotably on one of its peripheral edges and the annular disc is associated with a drive which is adapted to change the distance between the preferably stationary during operation annular disc 19 and the outlet opening 12.
  • the annular disc 19 is designed to be stationary during operation and does not rotate with the drum 1 with.
  • the radius of the E-line can be moved within the drum by a certain range.
  • the double conical drum in the region of its largest diameter solid discharge nozzles 21, which serve for the continuous discharge of solid particles S from the drum.
  • This embodiment is preferred. Embodiments without an additional solids discharge are also conceivable.
  • the displaceable annular disc leads to a significant improvement in the adjustability of the emulsion line (E-line) and to a better controllability and controllability of the process. This also results in an enlarged adjustment range of the separation zone.
  • E-line emulsion line
  • the outlet openings 12 may have a round shape in the manner of bores or may be e.g. Wedge-like or step-like widening from the inside out, which increases the control capability in different cases .. It could also be a tube placed in the outlet openings, which would have the advantage that the liquid flow does not attach to the drum.
  • This consists of a liquid outlet in the drum upstream disk 15 which extends from the outer periphery of the paring disc 10 to the outside and having a maximum circumferential radius which is greater than the largest radius to which the outlet openings 12 extend.
  • the standing still, non-rotating (shutter) disc 15 is in turn connected upstream of the drum 1, a kind of annular disc 16 as the first weir, which extends from the inner periphery of the drum cover of the drum 1 inwardly and whose inner radius is smaller than the largest Radius to which the disc 15 and the outlet openings 12 extend, so that in the region between the annular disc 16 and the outlet openings 12 (as 2nd weir) on the inner circumference of the drum cover of the drum 1, the Hydrohermitikringformat 14 is formed.
  • This chamber prevents the uncontrolled escape of gases or steam from the drum through the outlet openings 12 or labyrinths or other gaps or the like, which would cause a short-term instability in the region of the emulsion line - separation zone -.
  • the throttling device 13 alone can achieve an adjustability of the discharge radius of the heavy liquid phase of about 336 to 384 mm (ie 48 mm) or a compensation of the density variance (K) of 0.884 to 0.915 (0.031), because either by reaction to shifts or in product changes by changing the gap width of the gap 20 counteracted a displacement of the separation zone to keep them at a constant radius as possible to keep the process stable.
  • the peeling disk 10 alone can achieve an adjustment of the radius of the dividing line of 360 to 392 mm (32 mm) or a compensation of the density change (K) of 0.878 to 0.900 (0.022).
  • the throttling device 13 and the peeling disk 10 can achieve an adjustment of the separating zone or the radius of the E-line of 336 to 414 mm (corresponding to 78 mm) or a density ratio variance (K) of 0.863 to 0.915 (0.052).
  • a separate and independent water supply into the drum (not shown here, feasible, for example, by a concentric supply pipe within the supply pipe 4 for the product and further through the manifold into the drum) to provide in the three-phase separation - without a To exert additional hydraulic load on the stack of plates - to ensure that there is always a sufficient back pressure at the gap 20. If, on the other hand, the gap were not completely traversed, there would possibly be an uncontrolled shift in the e-line.
  • the discharge volume flow through the gap 20 is preferably observed and possibly also measured in order to prevent such dry runs and to minimize the volume of water to be added as much as possible.
  • the nozzle discharge capacity may be initially determined theoretically based on the machine design and drum rotation speed. This capacity is hereinafter referred to as "nominal" capacity or derivative rate.
  • the nozzles 21 will show wear and a period of time within which it is advisable to repair the solids discharge nozzles 21 may be indicated. This is advantageous because it is possible to maximize the time to change nozzles.
  • the measured "drain rate" is less than the nominal rate, one can conclude that one or more of the solids discharge nozzles 21 are clogged.
  • the system may be configured to automatically correct the effect of nozzle wear when determining whether the solids discharge nozzles are clogged or not.
  • the pressure drop across the throttle device depends on the flow rate or quantity and the size of the gap 20.
  • the pressure drop over the paring disc 10 depends on the flow rate and the throttling pressure on the valve 20 of the paring disc.
  • the pressure drops affect the discharge rates of the heavy and light phases. Combined and considered individually, the discharge line radii also influence the position of the E-line.
  • the user can conclude that a greater proportion of heavy phase is in the light phase and vice versa.
  • a stable separation process can be maintained although fluctuation in the product feed rate and composition may occur or density fluctuations of the heavy and / or lighter liquid phases LP and HP.
  • Such effects occur e.g. in natural products such as fish oil or in the treatment of crude oil (separation of water from the crude oil) or in the treatment of water (in particular separation of oil residues from the water).
  • a correction of the flow rate of the solids can be performed by measuring the solids content, since the solids density is a relatively constant parameter.
  • the light phase density and finally the density can be measured directly.
  • the inflow and outflow rates of the heavy and light phases can be determined.
  • This simple expert system can be supplemented by an online measurement of the exact heavy phase composition and the light phases. Neither the heavy nor the light phases typically have a polarity which would make measuring the volumetric concentration easy.
