Description

CYCLONIC CONDENSING AND G SYSTEM Field of the ion The present invention relates generally to a device for heat ged technology.

More ularly, it relates to a device for economically condensing hydrocarbon vapors in a renewable energy plant Background of the Invention The use of heat exchangers as cooling systems is well established in industry.

Examples of known devices include U.S. patent No. 4,858,681 to Sclzberger, U.S. patent No. 8,365,812 to Al·Hadhrami, U.S. patent No. 4,060,127 to Savin et. al., U.S. patent No. 3,168,136 to Ammon, and U.S. patent No. 3,258,068 to Hollister. These patents teach multistage heat exchangers to slowly cool a vapor. The disclosed systems of these patents use condensers that are bolted end to end on a slope so any liquid accumulating as a result of vapor condensation will flow down a slope or gradient.

However, existing designs of convention systems often require an nate amount of space to odate the structure of the cooling system. In addition, such tional cooling system configurations merely produce a low surface area inside the condensers thereby limiting their efficiency. Furthermore, the aforementioned designs do not allow for easy linkage and ication of its components such as in a daisy-chain configuration design. As a result, condensation of usable and re-useable fuel vapors may not be optimized. Accordingly, prior art designs may lead to char build-up and plugging of internal tubes within the condenser y reducing effectiveness of the system.

Thus, there is a need for producing a more efficient heat ge g system that provides capability for optimizing usable and re-usable fuel vapors. There is also a need for providing improved systems that reduce contaminants without employing added expenditures of additional equipment (such as external heat sources, electrical input or cooling media apparatus) for achieving the same.

[0036] Fractionation includes the separating of a mixture of hydro-carbon chains into a group of carbon chains or fractionations. l cracking is the process used by refineries to break down carbon chains of petroleum compounds so that the desired carbon compound can be ed. This process typically involves high heat, distillation, re-boiling, and energy intensive cooling processes. This application discloses an invention that will condense vapor produced by a reactor (e.g., a pyrolysis reactor). In doing so, the disclosed system utilizes a standard cyclone; a plurality of specialized cascading cyclones with internal cyclonic rotation fins that force incoming vapor to maintain a fixed amount of rotation regardless of the vapor's velocity, heat sinks that se condensation, reversing fins that force gases to reverse direction inside the cyclone decreasing vapor ty to increase heat loss; a main collection tank that allows for the controlling of the fuel flash point; a compact low temperature coil cooler that uses 100 percent of the cooling surface that allows for the production of higher y fuel; and, bubblers/scrubbers that produce back pressure into the pyrolysis reactor.

The disclosed subject matter improves on heat exchanged technology by providing a more efficient heat exchange cooling system that provides capability for optimizing usable and re-usable fuel vapors. Such vapors may be captured and utilized on any device able to run on gaseous fuel such as any ndensable petroleum fuel.

In addition, the disclosed t matter discussed herein s from the prior art as it employs modified rotation fins, internal e heat sinks, forced gas direction reversal inside of each cyclone, the y to control fuel flash points without an external heat source, separation of the collected fuels without an al het source, and compact low temperature coil cooler that uses one hundred percent of the cooling surface. 82_1 (GHMatters) P110127.NZ Furthermore, the disclosed subject matter s a chain design configuration so that the condensation of usable re-useable fuel vapors in optimized. The disclosed cyclonic condensing and cooling system is part of a re-useable energy technology and the prior art designs would lead to Char build-up and plugging of the tubes within the condenser reducing effectiveness.

Turning to the disclosed subject matter is directed to a cooling system ting of a plurality of e coolers (e.g., one standard cyclone cooler and one or more specialized e coolers) thereby forming the disclosed ic condensing and cooling system 100. According to disclosed ments, the standard cyclone cooler may be considered to be a first-type cyclone cooler having a first configuration, as explained herein.

The one or more specialized cyclone coolers may be considered to be second-type cyclone coolers. Thus, the one or more second-type coolers may have a substantially identical second configurations to respective other one or more second-type e coolers, as explained below. Yet, the first-type e cooler having the first configuration is different from the second-type cyclone coolers having the second configurations, as explained below.

By way of example, one standard e cooler is depicted as A in In an exemplary embodiment three specialized cyclone coolers are illustrated as B, C and D in FIG 1. Each of the specialized cyclone s B, C and D are of the type rated, for example, in An exemplary embodiment of the standard cyclone cooler may comprise a first configuration. An exemplary embodiment of the specialized cyclone coolers may comprise a second configuration, each of the second configurations being alike one another but different from the first configuration of the standard cyclone cooler. The disclosed cyclonic condensing and cooling system 100 may include a chiller 300, an air heat exchanger 400, two liquid bubblers/scrubbers 500, a main holding or main liquid fuel collection tank 136, and an expansion tank 142.

In an exemplary application, a pyrolysis r processes plastic waste material which may be shredded and fed n. Applying heat above 350 degrees Celsius will cause the shredded plastic material to melt and vaporize. The up-stream reactor es back pressure to assist in the thermal cracking of the carbon chains present in the plastic material.

The cyclonic condensing and g system 100 may be employed to produce the required back pressure required by the pyrolysis reactor. Such back pressure is achieved due to the 11733982_1 (GHMatters) P110127.NZ static friction of the pipe and cyclone s of the sed subject matter in addition to the water column re produced in the bubblers/scrubbers 500 (e.g., depicted in .

Turning to the first cyclone cooler is illustrated at 120a. First cyclone cooler is a standard e cooler. A standard cyclone cooler ts of an inlet section, body wall, cone to discharge and an internal tube. When the vapor or gas stream enters the cyclone it s around the body and down the cone, then up through the tube and out of the cyclone. The amount of rotation on the incoming gas, dictates the amount of rotation and centripetal force it es and particles being conveyed with the gas. This force separates the particles from the gas and drops through the cone, then out of the cyclone. The gas rotates and drops down the cone, increasing in velocity and pressure due to the smaller and smaller diameter on the cone. This action packs the gas stream at the bottom of the cone and forces it to rise back up and through the internal tube, then out of the e to the next cyclone. The rotations of the vapor within first cyclone cooler 120a are based on the velocity of the gas as it enters first cyclone cooler 120a. In the disclosed subject matter, a cyclone inlet is depicted in at 134 and at 134. Inlet 134 has a diameter of about 6 inches wherein its inlet velocity can accommodate a vapor or gas stream of about 3,234 feet per minute based upon the pyrolysis reactor's rate capability based upon the following values: approximately 2,000 pounds of shredded plastic material processed per hour at about 1,150 degrees Fahrenheit. As the pyrolysis r has about a 7 percent char rate, the remaining volume of shredded plastic processed (after the char is removed) is about 1,860 pounds per hour processed into a gaseous state. The gas weighs 0.78 ounces per cubic foot. Thus, standard cyclone cooler 120a receives gas at a rate of about 635 cubic feet per minute. The ambient temperature is assumed to be about 70 degrees Fahrenheit for purposes of exposure to heat loss.

The vapor remains in first cyclone cooler 120a for about 4 seconds. This allows for a heat loss of between about 3 and 8 s Fahrenheit. The fuel collected at a bottom 15la of first cyclone cooler 120a contains carbon chains that are C-28 or larger. First cyclone cooler 120a also collects large char particles that may have travelled into cyclonic condensing and cooling system 100. These char particles will drop out of the vapor stream and will be deposited to the rge hopper at the bottom 151a where it mixes with fuel containing carbon chains that are C-28 and larger. This fuel char mixture may be returned and re-fed into the pyrolysis reactor for further thermo cracking via a high temperature pump 137. The vapors leaving rd cyclone cooler 120a are traveling at a velocity of about 3,224 feet per 82_1 (GHMatters) P110127.NZ minute and will travel through a cross over pipe 135 for about 2.9 seconds. Due to the thin wall of cross over pipe 135, heat loss of the vapor as the vapor travels through cross over pipe 135 will be approximately 2 s Fahrenheit. This heat loss lowers the inlet vapor volume of the vapor entering the second cyclone cooler 120b.

[0045] Turning to a cross section of specialized e coolers 120b, 120c, and 120d (second cyclone cooler, third cyclone cooler and fourth cyclone cooler, tively) of illustrates the internal structure of specialized cyclone coolers (120b, 120c, and 120d) that forces gas vapors to follow a cyclonic path to maximize vapor contact with outer the outer body of the cyclone cooler (that is uous to ambient temperature) in order to dissipate heat and to effect condensation.

Accordingly, second cyclone cooler 120b (FIGS. 1 and 2) is a specialized cyclone cooler ucted with a unique configuration different from the standard/first cyclone cooler 120a. As illustrated in second cyclone cooler assembly 120b is illustrated in an assembled view 200, and ed view 202 and an internal view 204. Second e cooler may include a body portion 145 joined to a cone 150 in a final assembled state. Contrary to the standard cyclone cooler, the second cyclone cooler has onal internal components in a disclosed arrangement of the disclosed subject matter. Specifically, in tion, body portion 145 and cone 150 house an internal structure or internal tube comprising an outer tube structure 210 and inner tube structure 212. Inner tube structure may be regarded as an inner filler drum 148. Outer tube structure 210 has a cavity 214. In a final assembly, inner tube structure 212 is disposed within a cavity 214 of outer tube structure 210. Inner tube structure 212 comprises a cavity 216 for accommodating disbursed gases hrough.

The body 154 of outer tube structure 210 includes a first set of turning fins 149 ed along its exterior in a first rotational direction, as described below. A configuration of turning fins 149 may include an internal cyclonic rotation fin configuration. Inner tube structure 212 includes a second set of turning fins 147 disposed along its exterior traversing in a second rotational direction. A configuration of g fins 147 may e an internal cyclonic rotation fin configuration. In one embodiment, the second rotational direction may include a reverse or opposite cyclonic rotational fin direction to turning fins 149, as further described below.

Thus, in a final assembly, inner tube structure is disposed in cavity 214 of outer tube structure 210 to form an internal tube assembly. The al tube assembly is further 11733982_1 (GHMatters) P110127.NZ disposed within the cavity of the joined body portion 145 and cone 150. In the final assembly configuration, a first channel 206 is formed between an exterior of the outer tube structure 210 and the interior of the body portion 145. Additionally, a second channel is formed between an exterior of the inner tube structure 212 and an interior of the outer tube structure 210 within cavity 214. Turning fins 149 are disposed within first channel 206 in a first direction and turning fins 147 are disposed within second channel 208 in the second direction, as discussed below.

In select ments, the disclosed subject matter provides second cyclone cooler 120b designed with about 158 feet of turning fins 149. The distance between turning fins 149 is about 4 inches (the pitch) with the width of the flight being about 3 inches. Turning fins 149 may be designed having 12 spiral rotations with a 36 inch outside radius. Fins 147 placed on inner tube structure 212 may include 6 spiral rotations with the same pitch and width as turning fins 149. Turning fins 149 are attached inside the body 145 of second e cooler 120b to force the amount of rotations of received gases. This makes the gases come into contact with body 145 a fixed amount of times before entering a cone 150 disposed below.

The travel time through second cyclone cooler 120b is about 3.8 seconds based on the process rate of the reactor of about 2000 pounds of shredded c per hour. There is heat loss in second cyclone cooler 120b due to the friction produced by fins 149 as the fins act as heat sinks. As vapors cool, they condense and lose volume; loss of volume reduces the velocity of gas ng its velocity and creating more retaining time. This s in further heat loss within the cyclone coolers. (provides a schematic of the remaining cyclonic cooling system calculated losses for the disclosed subject matter.) Third cyclone cooler 120c (FIGS. 1 and 2) is cal to second e cooler 120b. Likewise, third cyclone cooler 120c is a lized cyclone cooler being constructed with a unique configuration different from the standard/first cyclone cooler 120a. The process involved in third cyclone cooler 120c is identical to second cyclone cooler 120b; third cyclone cooler 120c being ed and constructed in the same manner as second cyclone cooler 120b. In ion, vapors leave second cyclone cooler 120b and travel to third e cooler 120c via cross over pipe 126a. The g process continues reducing the volume of the vapor and reducing the velocity of the vapor.

Fourth cyclone cooler 120d (FIGS. 1 and 2) is identical to second cyclone cooler 120b and third cyclone cooler 120c. Likewise, fourth cyclone cooler 120d is a specialized 11733982_1 (GHMatters) P110127.NZ cyclone cooler being constructed with a unique configuration different from the standard/first cyclone cooler 120a. Fourth cyclone cooler 120d is designed and constructed in the same manner as second cyclone cooler 120b and third cyclone cooler 102c. In operation, vapors leave third cyclone cooler 120c and travel to fourth cyclone cooler 120d via cross over pipe 126b. The cooling process continues reducing the volume of the vapor and reducing the velocity of the vapor. A design configuration of fourth cyclone cooler 120d may allow vapor to leave this cyclone and enter into a forced air heat exchanger 400 (see, FIGS. 1 and 4). In an exemplary design, forced air heat exchanger (air cooled condenser) 400 has a total cross sectional area of about 1600 square inches inside the oval flatten tubes. This high surface area increases the on time and slows the velocity of the remaining gas stream to about 150 feet per minute and reduces the heat dramatically from approximately 100 degrees Celsius to 70 degrees Celsius due to the ambient air temperature. This creates a large amount of condensation that is collected inside oval flatten tubes 157 and allowed to drip back into fourth cyclone cooler 120d disposed located directly below. This returning liquid fuel, in turn, further cools the vapor leaving third cyclone cooler 120c. The vapor travels through forced air heat ger 400 and is pushed into chilled cooling coils of coil condenser 300 (FIGS. 1 and 3) via pipe 141.

Turning to an internal configuration 302 and exploded view 304 of coil condenser 300 is rated. Coil condenser 300 serves as a short carbon chain condensing unit. In an exemplary embodiment, coil condenser 300 is a cooler that is constructed with six internally coiled 1 inch tubes 167 that are submerged h a tank of d glycol 169.

The six l inch diameter stainless steel round tubes are in the form of a spiral. The spiral reduces the overall length of the 1 inch tubing from sixty feet where it is contained in an tus that is about five feet in height. The six coils are generally arranged evenly around each other in a circular pattern. This creates an even distribution of the flowing gases inside the coils. The spiral shape s in the slowing of the incoming vapors by the use of turning static pressure. These coils are attached through a top and bottom flange plate 170. This assembly is inserted into a drum housing 169 with ng s 168 and 169. The drum housing 169 is filled with a glycol product that acts as the media for the heat exchange. The glycol remains present inside this drum. A cooling coil 167 is introduced into the drum which cools the glycol. In turn the glycol cools the 1 inch tubing that is ng the vapors inside. 11733982_1 (GHMatters) P110127.NZ Cooling coil 167 is attached to a standard refrigeration system 144 ( and remains closed loop through the glycol drum 169. The vapors pass h cooling coil 167, allowing condensation to drip into the collection chamber 171. The vapor that does not turn into condensation exits the coil condenser at 174 after the vapor circles the glycol drum. The flange connection 170 at the bottom of the glycol drum allows the liquid to go in one direction and gas to go in another. The chamber 173 between the glycol drum and the housing is the location of where the vapors travel to the gas outlet at 174. This zone also sees the glycol temperature on the outside of the glycol drum 169 to further cool the vapor. The condensed vapor that exits coil condenser 300 as a liquid is collected in a smaller or secondary tank 129 ( and pumped to storage.

Coil condenser 300 is designed with bolted flange connections for access and service to all components of this equipment. Each e cooler and the coil chiller has a tank or collection hopper below them (at 151a, 15lb, 15lc, and 15ld). In the case of the cyclone coolers, the collection discharge hopper (at 151a, 15lb, 151c, and 151d) has a drain port, level indicator (at 153) ng connection and a fuel outlet port (spill over) (at 151p). The spillover 151p allows for the build-up of collected fuel to be discharged into a respected holding tank.

The first three cyclones coolers 120a, 120b, and 120c discharge into a first hold tank also regarded as the main holding tank 136 via control ball valves 139 (FIGS. 1 and 6).

The fourth cyclone 120d discharges in r or second holding tank also regarded as secondary tank 129 that is located beneath the chilling coil of coil condenser 300. ing to the disclosed subject matter, smaller or secondary tank 129 receives the lighter, cooler ted fuels. The lighter or cooler collected fuels may include r or shorter carbon chains (i.e., gasoline, naptha) as d to diesel which has longer carbon chains. Main holding tank 136 ts heavier heated fuels (i.e., those fuels having a higher boiler point).

Disclosed embodiments provide that main g tank 136 collects the heavier heated fuels as being filled from the cyclone s 120a, 120b, and 120c. Higher temperature fuels are regarded as those fuels having higher boiling points and higher flash point e.g., above 40 degrees Celsius. Although the first three cyclone coolers 120a, 120b, and 120c collect higher temperature fuels, some amount of light fuel (like benzene) may also be collected. The lighter fuels will vaporize from the heat of the holding fuels inside main holding tank 136 and drift up the tank column 121. A pump 122 located at the top of the expansion column 121 will pull 11733982_1 ters) P110127.NZ these vapors from main holding tank 136 before they can re-condense and force them into coil condenser 300. This allows for the collection of fuel of higher quality in main holding tank 136 by rising the flash point on the collected fuel. Disclosed cyclones coolers A, B, C, D all work together to collect fuels having a range of carbon to carbon chain structure. In accordance with disclosed ments, the configuration of cyclonic condensing and cooling system 100 allows heavier heated fuels to be collected by cyclone s A, B, C, and D while the lighter fuel is capable of being collected in coil condenser 300.

The chilled gases leave coil condenser 300 and travel to two bubbler tanks 500 that are connected in sequence h pipe connection 141. These tanks have an extended pipe from the inlet port that is submerged under the liquid water line at 181. This submerged pipe 181 causes back pressure to the system by the ance of the liquid in the bubbler tank. This is referred to as water column pressure. By using two tanks to achieve the water column pressure, the height can be divided. These bubbler tanks can contain different liquid ents as needed to remove any contaminants in the remaining vapors. As illustrated in the first tank is designed to hold water and is equipped with a level indicator 186 and a PH meter 187 to monitor the condition of the water. Water is used to remove sulfur and the buildup of sulfur will indicate a change in the PH. The second r contains caustic soda. This will capture any chlorine gas in the vapors. This tank also has a PH meter 187 and is also equipped with a level indicator 186 and level sensor.

[0057] The last tank on cyclonic condensing and cooling system 100 is a standard expansion tank 142. Expansion tank 142 is also designed to catch any liquid droplets that may travel through cyclonic condensing and cooling system 100. Pressure sensors and indicators r the reactor pressure from this point in the system.

In operation, the as gases are received within the disclosed cyclonic condensing and cooling system 100, embodiments of the disclosed subject matter force rotations of the gases through the system. Throughout on, the hot gases will lose heat from thermo contact loss with the outside body wall 145. In accordance with the design of the disclosed subject matter, the ng gasses are channeled down first channel 206 in a direction commensurate with a first onal direction enabled by turning fins 149 and up second channel 208 commensurate with a second rotational direction mandated by the placement of turning fins 147. In an exemplary embodiment, the second rotational ion may include a e rotational direction from the first rotational direction. Prior to sing up second 11733982_1 (GHMatters) P110127.NZ channel 208, embodiments of the disclosed subject matter allow the gases to pack generally at the bottom of cone 150 like a standard cyclone whereupon they are forced to reverse rotational ion before entering the internal tube (i.e., outer tube structure 210 and inner tube structure 212). This adds to the le separation, e the ga ses come to a complete stop before reversing direction, allowing the particles to fall out of the gas stream.

The design then uses the cyclone as a separator and a cooler/condenser. As hot gases lose heat, condensation is ted in the cooler area. By controlling the gas resident time inside the cyclone, a fixed condensing temperature can be achieved. By controlling this temperature, fuel can be distilled into c-chain groups between a group of cyclones.

[0059] Embodiments of the disclosed cyclonic sing and cooling system provide four cyclone coolers in series (at 120a, 120b, 120c, and 120d). The first cyclone cooler 120a collects the larger particles and higher carbon chain fuels only. The next three cyclone coolers 120b, 120c, and 120d separate the fuel grades (e.g., gasoline, petroleum, derived liquid for fuel) based on condensing temperatures. Separated fuels have temperatures which cause vaporization of the fuels to ignite when exposed to an open flame. This process is referred to as a flash point. The lower the carbon chain number in the fuel, the lower the temperature of the liquid fuel, that will cause the fuel to ignite. This temperature will be referred to as the "yield flash indicator" (YFI). In order to increase the YFI, the removal of the r carbon chains by use of heat is required.

[0060] Each cyclone collects vapor at a lower temperature than the one before it in the gas stream creating its own YFI value. Inside the internal tube at 154 is a reversed set of fins 147 connected to a filler drum 148 inside the tube. The rge of each cyclone cooler has a hopper, or discharge tank 151 to store condensed fuels. Each hopper can be ed to a holding tank by selected ball valves. A level indicator 153 is used to start the discharge of the collected fuels. The tion hopper also has a drain valve (at 139) for cleanout use.

The last cyclone cooler, the fourth, in the series (at 120d) will have an air contact heat exchanger 400 to insure full ambient cooling. This heat exchanger 400 condenses the last of the ambient temperature fuels and drips it back through the cyclone, acting as a reflux and cooling for the cyclone. The remaining vapors then pass through a coil type chiller 300 via a connecting pipe 141. This is a set of five coils (at 167) ing 65 feet in straight length each and wrapped around each other in an even g. The coils 11733982_1 (GHMatters) P110127.NZ 167 are set inside a tube filled with glycol 169 for chilling. This glycol is chilled with refrigerated coils 175 from an air conditioner compressor and controlled to in the set point temperature. The incoming vapors entering the coil condenser 300 at entrance 164 will condense and drip out of the chiller housing 171. The vapors then turn up from the bottom of the coils and travel to the gas outlet 174. On the way to this outlet port, the gases are again exposed to the cold wall (at 173) of the glycol chamber (at 169). This creates an effectiveness of 100% use of the ng chamber. The remaining gases are considered non-condensable at room temperature. This gas is referred to as syn-gas.

The syn-gas is then passed h two sets or bubbler/scrubbers 500. The first is filled to a fixed point with water. This water acts as a back pressure device, a flame arrester device and a scrubber. Along with the C4, hydrogen and other gases that make up the syngas , some unwanted gases also travel with the syn-gas from time to time. Without good control of the plastics entering in the reactor, chorine and sulfur can be introduced. The first bubbler will catch the sulfur in the water producing a weak dibasic acid, S02 + H20=H2S03.

[0063] The next bubbler also acts as a back pressure device, flame arrester and scrubber.

This time it is filled with caustic soda to scrub chorine. H=NaClO or salt and water.

The bubblers 500 are also equipped with a level l 186 so the level of the bubbling liquids is monitored as well as a PH meter 500 at 187 to indicate the condensing on the bubbling/ scrubbing liquids.

[0064] At this point the syn-gas is ready to be used. Thus, embodiments of the disclosed subject matter provide an improved means for ing and processing excess gas for use on any device capable of running on gaseous fuel, i.e., non-condensable petroleum fuels.

Accordingly, the burners for r-type systems are e of utilizing the fuel of the disclosed t matter. The syn-gas may also be used to power a generator that could power the electrical system of the reactor. The last item in the cooling system is a finish tank. This tanks act a drip collection if any liquids travel past the rs. It also serves as an expansion tank for the syn-gas. When the re inside this tank is at set point, the gas is allowed to be used.

Turning to an example design construction of cyclonic condensing and cooling system 100, disclosed embodiments may consist of four cyclones, two fuel tanks, an air cooled radiator, one glycol chilled coil condenser, two rs, and one expansion tank all attached to a structural steel frame. The cyclone coolers may be constructed from 10 gauge 11733982_1 (GHMatters) P110127.NZ stainless steel material. This material is selected due to its ability to withstand the internal pressure of the reactor while allowing heat to pass through the metal, cooling the incoming gas. The cyclone coolers t of a scrolled inlet, flanged body section, internal tube with fixed rotation fins, an interior baffle with reversed rotation fins, a bolted cone with support pads, and a discharge hopper with an outlet port.

The internal rotation fins are welded to one side of the cyclone tube ng for the condensed liquid to run h the fins to the discharge hopper. The internal tube also has a cone bottom to continue the vapor to pressurize inside the cyclone. Inside the internal tube is a cone drum that acts as a baffle. This baffle also has rotation fins welded to one side.

The cone drum baffle has a sloped top to allow for drainage of any condensation that may occur inside. The gas inlet and outlet discharge ports have a flange connection. The cone bottom is equipped with a coupling that acts as a level indicator. The cone bottom has a discharge part with a stub in flange for rotation and tion to the discharge hopper. The discharge hopper has a drain port, two outlet ports and the level indicator coupling.

[0067] The cyclone coolers (A, B, C, and D) are piped in a daisy chain configuration. The piping used between cyclone coolers is a thin wall schedule 10 stainless steel pipe with ANSI 150 flanges. This pipe is sloped from one cyclone coolers to the next and downhill to drain any condensation vapors. The last cyclone cooler in the daisy chain configuration has an air cooled heat exchanger connected to the top discharge flange. This air cooled heat ger reduces the remaining vapor temperature and allows for liquid to condense and return to the last e where it enters the discharge . This air cooled heat exchanger is constructed from oval-shaped tubing. The oval-shaped tubing is welded to the top and bottom seal plate, openings in the seal plate are welded to the oval-shaped tubing to allow vapors to pass h the inside of the tubing. Housing surrounds the tubing section and connects to an inlet chamber and gas discharge chamber. The fan is ted to the tube section housing. This part of the system uses ambient air and forces it across the e of the tubing to reduce the inside vapor temperature.

The fuel tanks may be ucted from heavy wall schedule 40 stainless steel pipe with pipe ends and connecting ports as needed to fill and discharge the incoming fuels. The top of the main tank 136 has an expansion column to allow light vapors to be removed from the collected liquids below. The second tank 129 is a standard g tank with inlet and outlet connections plus a coupling for level indication. The large tank 136 is constructed to 11733982_1 (GHMatters) P110127.NZ allow for high temperature fuel storage and collects from the first three cyclones. The r tank 129 will see low temperature fuels and is used to collect fuel from the last cyclone and the coil ser.

After the vapors leave the air cooled heat exchanger 400 it enters into a chilled coil condenser 300. The coil condenser is d above the small fuel tank 129. The condenser consists of six l inch diameter ess steel round tubes that have been rolled into a spiral.

The spiral reduces the l length of the 1 inch tubing to one tenth the . The spiral shape also assists in the g of the incoming vapors by use of the turning static pressure.

The coils are attached through a top and bottom flange plate. This assembly is inserted into a drum g with matching flanges. The drum housing is filled with a glycol product that acts as the media for the heat exchange. The glycol remains resident inside this drum. A cooling coil is introduced into the drum which cools the glycol. In tum the glycol cools the 1 inch tubing that cools the vapors inside. The cooling coil is attached to a standard refrigeration system and remains closed loop through the glycol drum. The vapors passing h the 1 inch coils, cool, so the coil condenser allows the produced condensation to drip to the bottom in the collection chamber, exiting the device. The special flange connection at the bottom of the glycol drum allows for liquid to go in one direction and gas to go in another. The chamber between the glycol drum and the outside is where the remaining vapors travel. This zone also is cooled by the glycol thus it benefits from double cooling. The coil condenser is designed with bolted flange connections for access and service to all components of this equipment.

The chilled gases leave the coil condenser then travel through two bubbler tanks 500. These tanks have an extended pipe from the inlet port that is ged under the liquid water line. This submerged pipe causes back pressure to the system by resistance of the liquid in the bubbler tank. This is referred to as water column pressure and by using two tanks the height can be divided between each one. An example is if total water column back pressure is 60 inches in one bubbler and 50 inches in the second bubbler, a total of 110 inches of water column back pressure is created. These bubbler tanks can contain different liquid components as needed to remove any inants in the remaining vapors. The first tank is designed to hold water and is equipped with a level indicator and a PH meter to monitor the condition of the water. Water is used to remove sulfur and the buildup of sulfur will be indicated by a change in the PH. The second bubbler contains caustic soda which will capture any chlorine 11733982_1 (GHMatters) P110127.NZ gas in the vapors. This is also red with a PH meter and this second bubbler is also equipped with a level indicator and level sensor.

The last tank on the e cooling system is a standard expansion tank 142 that is designed to catch any liquid droplets that may travel through the piping. Pressure sensors and tors mounted on this expansion tank keep track of the reactor pressure. Throughout the cyclonic condensing and cooling system 100 are differential pressure gauges. These gauges are used to identify any buildup or clog edge in the pipe or in any component of cyclonic sing and cooling system 100. The entire process is mounted on a bolted steel frame system. The frame system may utilize a standard A36 carbon steel frame, d and equipped with matching connection clips for all corresponding equipment. The size and shape of the equipment is designed for quick breakdown and transport in a standard sea ner.

Accordingly, the sed cyclonic condensing and cooling system 100 improves on heat exchanged logy as it does not require the bolting of the heat exchangers from end to end; takes up much less space than if the current technology was used; increases the surface area inside of the condensers that make up a heat exchanger; es much lower velocity of the vapor when entering the condenser; allows for the continued release of the condensed liquid after the heat exchange and on, allowing the non-condensed vapors to move to the next condenser, and; prevents the build-up of char that could plug the tubes within the condensers.
