It is possible that an apparatus or process described below is not an embodiment of any exclusive right granted by issuance of this patent application. Any invention disclosed in an apparatus or process described below and for which an exclusive right is not granted by issuance of this patent application may be the subject matter of another protective instrument, for example, a continuing patent application, and the applicants, inventors or owners do not intend to abandon, disclaim or dedicate to the public any such invention by its disclosure in this document.
Referring to FIG. 1, an example fluid processing assembly 100 is shown. The fluid processing assembly 100 generally includes a reactor assembly 200, a product collection assembly 300, and a sample collection assembly 400.
Referring to FIG. 2, the reactor assembly 200 includes a lumen 201, within which a reaction occurs. In the example shown, the lumen 201 is formed by a tube 202. In some examples, the tube may be a capillary, for example a glass capillary. As will be described in further detail below, the lumen 201 may be pressurized by a downstream pressurized gas source (i.e. back pressure may be applied to the lumen). Optionally, the lumen may be of any suitable construction, including, for example, a capillary, a tube/conduit of any suitable cross-section (round, square, etc), and a channel in a chip. Further, the lumen may be formed from any suitable material in whole or in part, including microwave radiation transparent materials (such as glass or alumina) whereby the microwave irradiation directly heat the product material, and/or microwave radiation absorbing materials (such as silicon carbide, graphite, charcoal, etc.) whereby the microwaves heat the lumen material which then heats the reactant/product material contained in the lumen.
Referring still to FIG. 2, in the example shown, the lumen 201 receives an inlet stream 204. The inlet stream 204 flows into the lumen 201 from a mixer 206, which is in communication with a material supply array 208. In alternate examples, the lumen 201 may receive more than one inlet stream, and mixing may occur within the lumen 201.
Referring still to FIG. 2, the reactor assembly 200 further includes an energizing device 210 for supplying energy to an energizable portion 212 of the lumen 201. In some examples, the energizing device may be an irradiating device which irradiates an irradiation zone, and the energizable portion 212 may be within the irradiation zone. For example, as shown in FIG. 2, the energizing device 210 is a microwave irradiating device 210. The microwave irradiating device 210 irradiates the energizable portion 212 of the lumen 201 with microwave irradiation. The microwave irradiation device can heat the contents of the energizable portion 212 of the lumen 201, and may facilitate a reaction. For example, the material supply array 208 and mixer 206 may provide a solution of reactants to the lumen 201. When heated in the energizable portion 212 of the lumen 201 by the microwave irradiating device 210, the reactants may undergo a chemical reaction to yield one or more products. As mentioned above, the lumen 201 may be pressurized in order to facilitate the reaction. For example, the lumen may be pressurized in order to prevent or inhibit a phase change within the lumen, and to maintain the reactants in the liquid phase, which may facilitate the reaction.
In the example shown, the microwave irradiating device 210 supplies energy to essentially the entirety of the lumen 201, and the entirety of the lumen 201 may be considered to be the energizable portion 212. In other examples, only a portion of the lumen 201 may be the energizable portion. For example, the inlet and outlet ends of the lumen 201 may be positioned such that they are outside of the irradiation zone, and are not irradiated by the microwave irradiating device.
As mentioned above, in some examples, a chemical reaction may occur within the lumen 201. In other examples, other types of reactions may occur in the lumen 201. Such reactions may include, for example, pasteurization sterilization, or fluid derivation.
As mentioned above, in some examples, the energizing device may be a microwave irradiating device. In other examples, the energizing device may be an ultrasound device, a photo device such as a light, or a thermal device such as a heat exchanger, oven, resistive heating, inductive heaters, photo irradiation or heating tape.
Referring still to FIG. 2, a primary product stream 214, containing the product(s) of the reaction, is dispensed from the lumen 201 and is directed to the product collection assembly 300. In the example shown, the product collection assembly 300 includes a primary product collection assembly 302, and a downstream bulk product collection assembly 305. The primary product collection assembly 302 is in fluid communication with the lumen 201 for receiving the primary product stream 214. In the example illustrated, at least a portion of the primary product collection assembly is pressurized by a pressurized gas source, which applies back pressure to the lumen 201. The downstream bulk product collection assembly 305 is, in the example illustrated, at atmospheric pressure.
Referring still to FIG. 2, in the example shown, the primary product collection assembly 302 includes a primary product collection vessel 304. The primary product collection vessel 304 is pressurized and is generally sealed to the external atmosphere (i.e. in the example shown, the primary product collection vessel 304 is the portion of the primary product collection assembly 302 that is pressurized). A drip tube 306 is mounted within the primary product collection vessel 304. The drip tube 306 receives the primary product stream 214, and the primary product stream 214 drips from the drip tube 306 into the primary product collection vessel 304.
As mentioned above, in the example shown, the primary product collection vessel 304 is pressurized by a pressurized gas source, which in turn pressurizes (i.e. applies back pressure to) the primary product stream 214 and the lumen 201, and in order to facilitate the reaction in the lumen 201. When using conventional physical backpressure regulators, contact between the product stream and regulator can result in fouling of the regulator, which in some instances may interrupt the operation of the system. This may cause premature halting of a production run. In the example illustrated, backpressure is applied to the system by pressurizing the primary collection vessel 304, via a pressurized gas, with a sufficiently high pressure gradient to prevent backflow of product liquid into the gas system, and the liquid product stream is dripped into the pressurized primary product vessel 304 which eliminates the need for direct physical contact between a back pressure regulator and the product stream.
In the example shown, a pressurized gas source 308 is connected to and supplies pressurized gas to the primary product collection vessel 304 to pressurize the primary product collection vessel 304, the drip tube 306, the primary product stream 214 and the lumen 201. In order to maintain flow from the lumen 201 to the primary product collection vessel 304, the inlet stream 204 may be pressurized at a greater pressure than the back pressure supplied by the pressurized gas source. For example, one or more pumps (not shown) may be used to direct the inlet stream 204 into the lumen 201 at a greater pressure than the back pressure supplied by the pressurized gas source.
The pressurized gas source may be of any suitable configuration. In the example shown, the pressurized gas source 308 includes a gas supply tank 310, a pressure ballast 312, and various check valves, shut-off valves, vents, and regulators. The pressurized gas may be, in some examples, an inert gas such as nitrogen or argon. In other examples, the pressurized gas may be a reactive gas, and may, for example, participate in the reaction it the lumen.
In some examples, the reactor assembly 200 may be operated continuously, and the product collection assembly 300 may be operated semi-continuously. Specifically, in the example shown, the reactor assembly 200 may be operated continuously, and the primary product collection vessel 304 may continuously receive the primary product stream 214 and semi-continuously dispense a bulk product stream 314 to the bulk product collection assembly 305. More specifically, in the example shown, the product collection assembly 300 is configured such that the primary product stream 214 may continuously build up delivered product in the primary product collection vessel 304, until a desired volume is reached. When the desired volume is reached, the supply of pressurized gas may be shut-off, and an outlet valve 317 of the primary product collection vessel 304 may be opened to de-pressurize the system and to dispense the bulk product stream 314 from the primary product collection vessel 304 into a bulk product collection vessel 316 of the bulk product collection assembly 305. The outlet valve 317 may then be closed, and the system may be re-pressurized.
In alternate examples, the reactor assembly and product collection assembly may both be operated continuously. Specifically, as will be described in further detail below, the primary product collection assembly may be configured to continuously dispense the bulk product stream into the bulk product collection vessel without depressurizing the system, so that the system can be run continuously.
Referring still to FIG. 2, in the example shown, the energizable portion 212 of the lumen 201 is positioned exterior to the primary product collection assembly 302, and more specifically, exterior to the primary product collection vessel 304. In other words, the energizable portion 212 of the lumen 201 is not housed within the primary product collection vessel 304. The primary product collection vessel 304 may therefore optionally be non-transparent to microwave irradiation and/or more chemically resistant. For example the primary product collection vessel 304 may be made from a metal, metallic material or other material that is not suitable for use in forming the lumen 201. This may allow the product collection vessel 304 to have different mechanical and/or chemical properties from the lumen 201. For example the product collection vessel 304 may have higher heat resistance, greater strength, greater durability, and/or a greater chemical resistance, etc.
Referring back to FIG. 1, the fluid processing assembly 100 further includes a valve 102 (also referred to as a sample valve) downstream of the lumen 201 and upstream of the primary product collection assembly 302, through which the primary product stream 214 flows. The valve is useable to divert a sample of the primary product stream 214 away from the primary product collection assembly 302 and to the sample collection assembly 400. In the example shown, the valve 102 is configured to divert the sample without de-pressurizing the primary product collection vessel 304 and the lumen 201.
Referring to FIGS. 3 to 5, in the example shown, the valve 102 is a multi-port multi-position valve. The valve 102 is movable to direct the primary product stream 214 from the lumen 201 (shown in FIG. 2) to the primary product collection assembly 302, isolate a plug 118 from the primary product stream 214, and divert the plug 118 to a sample stream 402 of the sample collection assembly 400, while generally maintaining the pressure in the lumen 201 and the primary product collection vessel 304. As used herein, the phrase “maintaining the pressure” indicates that that while insignificant pressure fluctuations that do not materially affect the process may occur, substantial changes in pressure, such as depressurization to atmospheric pressure, do not occur. In the example shown, the valve 102 is a 6-port 2-position valve, and includes ports 104, 106, 108, 110, 112, and 114. The lumen 201 is in fluid communication with port 104, and the primary product collection assembly 302 is in fluid communication with port 106. A liquid solvent stream 115 from a solvent pump 116 is in fluid communication with port 112, and the sample stream 402 of the sample collection assembly 400 is in communication with port 114. The liquid solvent material, like the liquid product material is generally understood to be incompressible, which can help facilitate pressurization of the system.
In the example shown, the valve 102 is movable between a first position, shown in FIGS. 3 and 5, and a second position, shown in FIG. 4. Referring to FIG. 3, when the valve 102 is in the first position, port 104 and port 106 are in fluid communication, and the primary product stream 214 is directed from the lumen 201 to the primary product collection assembly 302. Further, when the valve 102 is in the first position, ports 108, 110, 112, and 114 are in fluid communication, and solvent is directed from the solvent pump 116 to the sample stream 402. Referring to FIG. 4, when the valve 102 is moved to the second position, ports 104, 108, 110, and 106 are in fluid communication, and a loop defined between ports 108 and 110 is positioned in fluid communication with the reactor assembly 200 and is populated with liquid plug 118 from the primary product stream 214. While the system is in operation, the loop between ports 108 and 110 can become partially and/or completely filled with the reactant/product stream. Further, when the valve 102 is in the second position, ports 112 and 114 are in fluid communication, and solvent continues to be directed from the solvent pump 116 to the sample stream 402. Referring to FIG. 5, when the valve 102 is moved back to the first position, the primary product stream 214 is again directed from the lumen 201 to the primary product collection assembly 302, and the plug 118 is isolated from the primary product stream 214 and can be pushed with solvent from the solvent pump 116 towards to the sample stream 402. Optimally, in between collections, clean solvent can be pushed through the loop between ports 108 and 110 which may help clean the loop.
As can be seen in FIGS. 3 to 5, whether the valve 102 is in the first position or the second position, the lumen 201 is in fluid communication with the primary product collection vessel 304, and in fluid isolation of the sample stream 402 and the exterior atmosphere.
In use, when the reactor assembly 200 is in operation, the valve 102 may be periodically moved from the first position to the second position (i.e. moved a first time), and from the second position back to the first position (i.e. moved a second time), in order to divert a sample of the primary product stream 214 away from the primary product collection assembly 302 and towards the sample collection assembly 400, while maintaining the pressure in the lumen 201 and the primary product collection vessel 304.
Referring now to FIG. 6, an example sample collection assembly 400 is shown in further detail. The sample collection assembly 400 generally includes the sample stream 402, an automatic actuator 404, and a sample collection vessel 406.
Referring still to FIG. 6, the sample stream 402 includes an inlet end portion 408 (shown in FIGS. 3 to 5), and an outlet end portion 410. The inlet end portion 408 is connectable in fluid communication with the primary product stream 214 upstream of the primary product collection assembly 302 for receiving a sample of the product. In the example shown, the inlet end portion 408 is connected to port 114 of the valve 102, so that when the valve 102 is moved from the first position, to the second position, and back to the first position, the inlet end portion 408 receives a sample of the primary product stream 214. The outlet end portion 410 of the sample stream 402 includes a fluid delivery conduit, which in the example illustrated is provided as a needle 411, which may be inserted into the sample collection vessel 406, as will be described in further detail below.
Referring still to FIG. 6, in the example shown, the sample collection vessel 406 includes a glass vial 407 having a piercable stopper 409. In other examples, the sample collection vessel 406 may be another suitable vessel, such as a test tube.
Referring now to FIGS. 6 and 9, the automatic actuator 404 is coupled to the outlet end portion 410, and is operable to move the outlet end portion 410 towards and away from a dispensing position (the dispensing position is shown in FIG. 9). Referring to FIG. 9, when the outlet end portion 410 is in the dispensing position, the needle 411 is inserted through the stopper 409 of the sample collection vessel 406, so that the outlet end portion 410 is in fluid communication with the sample collection vessel 406.
In the example shown, the automatic actuator includes a movable frame 412 in which the needle is mounted, a robot (not shown) for moving the frame 412, a motor 413 for moving the needle 411 within the frame, and a vessel grip 415 for gripping the sample collection vessel 406
In the example shown, the sample collection assembly 400 further includes a gas injection line 414 connectable in fluid communication with the sample collection vessel 406 for injecting gas into the sample collection vessel 406, and a gas withdrawal line 416 connectable in fluid communication with the sample collection vessel 406 for removing gas from the sample collection vessel 406. The gas injection line 414 may be connected to a gas source 418, such as an inert gas. The gas withdrawal line 416 may be connected to a vacuum pump 420. Both the gas injection line 414 and the gas withdrawal line 416 include a needle 421, 422, respectively, which may be inserted through the stopper of the sample collection vessel 406.
Referring now to FIGS. 6 to 9, an example series of steps for operating the sample collection assembly 400 will be described. The steps may be under automatic control, or may be carried out manually. In examples where the steps are under automatic control, the timing of the various steps may be based on the status of the valve 102. For example, the steps may be initiated when the valve 102 is actuated to divert a sample to the sample stream 402. Referring to FIGS. 6 to 8, when the plug 118 of the sample is approaching the outlet end portion 410 of the sample stream 402, the robot may be engaged to move the frame 412 from a home position (shown in FIG. 6), towards the sample collection vessel 406 (as shown in FIG. 7). The robot may then move the frame 412 downwardly so that the needles 421, 422 are inserted through the stopper 409 of the sample collection vessel 406, and so that the vessel grip 415 grips the sample collection vessel 406 (as shown in FIG. 8). The vacuum pump 420 may then be activated to purge the sample collection vessel 406 of the gas contained therein, and to fill the sample collection vessel 406 with the gas from the gas source 418 (e.g. an inert gas). The motor 413 may then be actuated to move the needle 411 to the dispensing position, as shown in FIG. 9, so that the sample is dispensed into the sample collection vessel 406.
In some examples, the sample collection assembly 400 may include a sample analysis apparatus (not shown), such as a gas or liquid chromatograph, optionally fitted with suitable technologies such as EI (electron ionization), CI (chemical ionization), ESI (electrospray ionization), APCI (atmospheric pressure chemical ionization), TCD (thermal conductivity detector), FID (flame ion detector), or CCD (catalytic combustion detector). Further examples of analysis apparatuses include NMR, IR, UV-VIS, or PDA (photo diode array) in tandem or in parallel with chromatography. The sample analysis apparatus may be operable to receive at least a portion of the sample of the product, and analyze the sample. For example, the sample collection vessel 406 may be transferred to sample analysis apparatus (for example by the robot), so that the sample analysis apparatus may withdraw a portion of the sample therefrom and analyze the portion. In a further example, a portion of the sample may be transferred from the sample collection vessel 406 to another vessel, which may be received by the sample analysis apparatus. In a further example, the sample collection assembly 400 may be configured to carry out various processing steps on the sample prior to forwarding a portion of the sample to the sample analysis apparatus. For example, various components, such as a solvent and/or a reactant, may be added to or removed from the sample (for example to concentrate the sample).
Data derived from the analyses of the sample analysis apparatus can be provided to a platform of a system control manager platform (not shown) to rationally alter parameters of the fluid processing assembly (e.g., process temperature, flow-rate, stoichiometry, pressure, extracted sample volume, dilution volume, concentration, choice of dilutant, chemical contributors (e.g., reagents, catalysis, solvent, promoter) and any other factors that may influence the process). This may be done, for example, to optimize efficiency and/or minimize safety-related risks. The system control manager may be capable of controlling the fluid processing assembly with built-in artificial intelligence, using basic system algorithms as well as user-defined parameter boundaries. The system control manager platform may also be amenable to manual intervention, either on-site or from a remote location.
Various valves or other components may be positioned in the sample stream 402 between the inlet end portion 408 and the outlet end portion 410. For example a valve may be positioned in the sample stream 402 for diverting the contents thereof to waste.
In alternate examples, the automatic actuator may be without a vessel grip. In some such examples, the frame may be positioned above the vessel, without gripping the vessel, and the various needles may pierce the stopper from this position. In other examples, a vessel guide may be provided instead of a vessel grip. The vessel guide may aid in positioning aligning the frame above the vessel without gripping the vessel.
Referring now to FIGS. 10 and 11, an alternate example product collection assembly 1000 is shown, in which like reference numerals, incremented by 700, are used to refer to like features to the product collection assembly 300. The product collection assembly 1000 includes a primary product collection assembly 1002 configured to continuously receive the pressurized primary product stream 214 from the reactor assembly (not shown), and to continuously dispense a bulk product at atmospheric pressure to the bulk product collection assembly 1005, while maintaining the pressure in the lumen 201.
Referring to FIG. 10, the primary product collection assembly 1002 includes a first primary product collection vessel 1004a, and a second primary product collection vessel 1004b. A stream selector valve 1018 is downstream of the lumen 201 and upstream of the first 1004a and second 1004b primary product collection vessels. The stream selector valve 1018 is movable between a first position, shown in FIG. 10, where the primary product stream 214 is directed to the first primary product collection vessel 1004a, and a second position, shown in FIG. 11, where the primary product stream 214 is directed to the second primary product collection vessel 1004b. 
Referring still to FIG. 10, a pressurized gas source 1008 is connected to the first primary product collection vessel 1004a via a first pressure line 1020a and a first pressure valve 1022a, and to the second primary product collection vessel 1004b via a second pressure line 1020b and a second pressure valve 1022b. The pressurized gas source 1008 is operable to selectively supply pressurized gas to the first primary product collection vessel 1004a, and/or the second primary product collection vessel 1004b, to pressurize the first primary product collection vessel 1004a, and/or the second primary product collection vessel 1004b, as well as the lumen 201 and the primary product stream 214. Other suitable valving and hardware may be provided in the lines between the product collection vessel 1004a (or 1004b). For example, control valves 1023a and 1023b may be provided between primary collection vessels 1004a and 1004b and the valve 1018. Providing control valves 1023a and 1023b may allow the primary collection vessels 1004a and 1004b to be isolated from the system, which may allow the primary collection vessels 1004a and 1004b to be emptied into the bulk collection vessels 1016a and 1016b without significantly depressurizing the system upstream from the control valves 1023a and 1023b, including portions of the lines provided between the control valves 1023a and 1023b and the valve 1018. This may help prevent pressure surges in the system when the control valves 1023a and 1023b are opened and closed.
Referring still to FIG. 10, the bulk product collection assembly 1005 includes a first bulk product collection vessel 1016a and a second bulk product collection vessel 1016b, both of which are at atmospheric pressure. The first bulk product collection vessel 1016a receives bulk product from the first primary product collection vessel 1004a via a first bulk product stream 1014a, and the second bulk product collection vessel 1016b receives a bulk product from the second primary product collection vessel 1004b via a second bulk product stream 1014b. A first outlet valve 1017a is provided between the first primary product collection vessel 1004a and the first bulk product collection vessel 1016a, and a second outlet valve 1017b is provided between the second primary product collection vessel 1004b and the second bulk product collection vessel 1016b. The first 1017a and second 1017b outlet valves may be selectively opened or closed to control the flow of the bulk product between the first primary product collection vessel 1004a and the first bulk product collection vessel 1016a, and the second primary product collection vessel 1004b and the second bulk product vessel 1016b, respectively. Alternatively, instead of providing two separate vessels 1016a and 1016b, a single bulk product collection vessel 1016 (shown using dashed lines in FIG. 11) may be provided to collection the product from both primary collection vessels. This may be advantageous during production when the product is to be produced and collected as defined batches.
Referring still to FIG. 10, in operation, the stream selector valve 1018 may be positioned in the first position, so that primary product stream 214 is directed to the first primary product collection vessel 1004a, and is in fluid isolation of the second primary product collection vessel 1004b. Further, the first pressure valve 1022a may be positioned so that pressurized gas is supplied to the first primary product collection vessel 1004a, and the first outlet valve 1017a may be closed, so that the first primary product collection vessel 1004a, the lumen 201, and the primary product stream 214 are pressurized. The reactor assembly 200 may be continuously operated, and the primary product stream 214 may flow into the primary product collection vessel 1004a. 
Referring now to FIG. 11, when a desired volume of product is reached within the first primary product collection vessel 1104a, the second pressure valve 1022b may be positioned so that pressurized gas is supplied to the second primary product collection vessel 1004b, and the second outlet valve 1017b may be closed, so that the second primary product collection vessel 1004b is pressurized. The stream selector valve 1018 may then be moved to the second position, so that the primary product stream 214 is directed to the second primary product collection vessel 1004b, and the pressure in the lumen 201 is maintained. The reactor assembly 200 may continue to be operated, and the primary product stream 214 will flow into and be contained within the second primary product collection vessel 1004b. 
Referring still to FIG. 11, when the stream selector valve 1018 is in the second position and the primary product stream 214 is in fluid isolation of the first primary product collection vessel 1004a, the first pressure valve 1022a may be positioned so that the supply of pressurized gas to the first primary product collection vessel 1004a is stopped. The first outlet valve 1017a may then be opened, so that the product in the first primary product collection vessel 1004a flows into the first bulk product stream 1014a and is collected in the first bulk product collection vessel 1016a. 
When a desired volume of product is reached within the second primary product collection vessel 1004b, the various valves may be switched back to the positions shown in FIG. 10, so that the lumen 201 remains pressurized and directs the primary product stream 214 to the first primary product collection vessel 1004a, and the product in the second primary product collection vessel 1004b flows through the second bulk product stream 1014b and is collected in the second bulk product collection vessel 1016b. 
By operating the product collection assembly as described above with respect to FIGS. 10 and 11, the primary product collection assembly 1002 may continuously receive the pressurized primary product stream 214 from the reactor assembly 200, and continuously dispense a bulk product at atmospheric pressure to the bulk product collection assembly 1005, while the pressure in the lumen 201 is maintained.
Referring now to FIGS. 12 and 13, an alternate example product collection assembly 1200 is shown, in which like reference numerals, incremented by 900, are used to refer to like features to the product collection assembly 300. The primary product collection assembly 1202 includes a valve 1224 downstream of the lumen 201 and the sample valve 102 for receiving the primary product stream 214. The valve 1224 may also be referred to as primary product collection valve 1224. Similarly to the example of FIGS. 10 and 11, the primary product collection assembly 1202 is configured to continuously receive the pressurized product stream 214 from the reactor assembly 200, and to continuously dispense a bulk product at atmospheric pressure to the bulk product collection assembly 1205, while maintaining the pressure in the lumen 201.
Referring to FIG. 12, the valve 1224 may be a multi-port multi-position valve. In the example shown, the valve is an eight-port two-position valve, having ports 1226, 1228, 1230, 1232, 1234, 1236, 1238, and 1240. The valve 1224 includes a first loop 1242, between ports 1228 and 1236, and a second loop 1244, between ports 1232 and 1240. Further, port 1226 is connected in fluid communication with the lumen 201 and the primary product stream 214, port 1230 is connected in fluid communication with a bulk product collection vessel 1216 at atmospheric pressure, port 1234 is connected in fluid communication with a pressurized gas source 1208, and port 1238 is connected to a pump 1246.
The valve 1224 is movable between a first position, shown in FIG. 12, and a second position, shown in FIG. 13. Referring to FIG. 12, when in the first position, port 1226 is connected to port 1228, port 1230 is connected to port 1232, port 1234 is connected to port 1236, and port 1238 is connected to port 1240. In this configuration, the first loop 1242 is in fluid communication with the lumen 201 via the primary product stream 214, as well as the pressurized gas source 1208. The second loop 1244 is in fluid communication with the pump 1246 and the bulk product collection vessel 1216. If the reactor assembly 200 is operated, the pressurized gas source will pressurize the first loop 1242, and re-establishes the fluid communication between the primary product stream 214, and the lumen 201, and the primary product stream 214 will flow into the first loop 1242. If the pump 1246 is operated, the contents of the second loop 1244 will flow towards the bulk product collection vessel 1216 of the bulk product collection assembly 1205.
When the contents of the first loop reach port 1236, the valve may be moved to the second position, shown in FIG. 13. When in the second position, port 1226 is connected to port 1240, port 1228 is connected to port 1230, port 1232 is connected to port 1234, and port 1236 is connected to port 1238. In this configuration, the first loop 1242 is in fluid communication with the pump 1246 and the bulk product collection vessel 1216, and the second loop 1244 is in fluid communication with the lumen 201 via the primary product stream 214, as well as the pressurized gas source 1208. If the reactor assembly 200 continues to operate, the pressurized gas source 1208 will pressurize the second loop 1244 and the lumen 201, and the primary product stream 214 will flow into the second loop 1244. If the pump 1246 continues to operate, the contents of the first loop 1242, which was filled with product from the primary product stream 214 when the valve 1224 was previously in the first position, will be pumped towards bulk product collection vessel 1216.
As can be seen in FIGS. 12 and 13, by repeatedly actuating the valve 1224 between the first position and the second position, the first loop 1242 and second loop 1244 are alternately pressurized, and the primary product stream 214 is alternately directed to the one of the first loop 1242 and the second loop 1244 that is pressurized. Further, when not pressurized, the first loop 1242 and second loop 1244 are connected to the pump 1246, so that their contents are directed to the bulk product collection vessel 1216. By operating the product collection assembly in this manner, the primary product collection assembly 1202 may continuously receive and pressurize the primary product stream 214 from the reactor assembly 200, and continuously dispense a bulk product at atmospheric pressure to the bulk product collection assembly 1205, while the pressure in the lumen 201 is maintained.
In some examples, the actuation of the valve 1224 may be automatically controlled, for example by a computer, and the timing of the actuation may be determined by the computer based on the size of the loop.
In the particular example shown in FIGS. 12 and 13, the primary product collection assembly does not include a primary product collection vessel.
In the example of FIGS. 12 and 13, the first loop and second loop are external to the body of the valve 1224, and may be variable in size. In alternate examples, the first loop and second loop may be internal to the body of the valve 1224.
Optionally, as indicated by the use of dashed lines in FIGS. 12 and 13, while the system is in use some or all of the solvent or any other suitable inert fluid used by the pump 1246 to drive product out of the product filling loop 1244 in FIG. 12 or loop 1242 in FIG. 13 and into vessel 1216 can be temporarily accumulated and/or held in a portion of the pressurized gas source 1208. Optionally, the accumulated fluid can be intermittently or continuously withdrawn from the pressurized gas source 1208. Optionally, the solvent collected in the pressurized gas source 1246 may be removed from the system and discarded, or alternatively at least a portion of the accumulated fluid may be recycled back into the system. The recycled fluid may be reintroduced in to the system at any suitable location and/or using any suitable means.
In the example illustrated, the pressurized gas source 1208 is in fluid communication with a multistage pressure controlling device 1211 via an exit line 1219. Device pressure controlling device 1211 is capable of accepting and momentarily isolating the inert liquid from 1208 before draining the liquid into a collection vessel 1221. This may help facilitate removal of fluid from the system without causing significant depressurization of the system. The collection vessel 1211 can also help facilitate this process with the aid of any suitable back-pressure generating barrier. Alternatively, or in addition to removing some of the fluid via exit line 1219, at least a portion of the accumulated solvent can be reintroduced to the system, for example via a recycling line 1217 which is connected to the pump 1246 (either upstream or downstream from the pump 1246) stream either manually or through valves. In the illustrated example, the system includes an optional recycle stream carried in recycle line 1217 (shown using dashed lines) that is configured to facilitate unidirectional flow. This may help prevent fluid from flowing from the pump 1246 to the pressurized gas source 1208 via the recycle line 1217. To facilitate unidirectional flow the system may be provided with any suitable flow regulating apparatus, including, for example, a check valve 1213.
In any of the examples described above, various additional valves can be included in various positions in the assembly. For example, one or more additional valves may be positioned in the primary product stream or in the bulk product stream for diverting a second sample of the product to the sample collection assembly, or for diverting a portion of the product to waste.
While the above description provides examples of one or more processes or apparatuses, it will be appreciated that other processes or apparatuses may be within the scope of the accompanying claims.
