摘要： A flash chamber sized to receive the effluent discharged from a polyolefin reactor during normal operation of the reactor and during a reactor dump, advantageously eliminating a reactor dump tank or alternate flash tank from the equipment outlay of a polyolefin manufacturing process. The flash chamber is sized to hold at least the polyolefin solids discharged from the reactor. A condenser fluidically coupled to an overhead portion of the flash chamber is sized to condense the flow rate of vaporized hydrocarbon (e.g., diluent, monomer, etc.) discharged overhead from the flash chamber during normal operation and during the reactor dump.
摘要翻译：闪蒸室的尺寸适于接收在反应堆的正常操作期间和反应器堆放期间从聚烯烃反应器排出的流出物，有利地从聚烯烃制造过程的设备消耗中消除反应堆倾倒罐或替代闪蒸罐。闪蒸室的尺寸至少保持从反应器排出的聚烯烃固体。流体耦合到闪蒸室的顶部部分的冷凝器的尺寸被设定为在正常操作期间和在反应堆堆放期间冷凝从闪蒸室排出的汽化烃（例如稀释剂，单体等）的流速。

摘要： A polyolefin production system, comprising a polymerization reactor (such as a polyethylene loop slurry reactor) and a fractionation system that receives reactor effluent processed in a diluent/monomer recovery system for recycle to the reactor and to suppliers. A conduit diverts a portion of a reflux flow comprising monomer, such as ethylene, from within the fractionation system to the polymerization reactor, providing for less venting of monomer, such as ethylene, to the supplier. Accordingly, monomer yield is advantageously increased, as the monomer returned to the reactor displaces monomer feedstock to the reactor. The reflux flow may originate from a condensed overhead lights from a diluent recycle column disposed in the fractionation subsystem. The diluent recycle column may receive a stream comprising diluent and monomer as feed from the diluent/monomer recovery subsystem, and may receive the non-diverted portion of the reflux flow as reflux.
摘要翻译：一种聚烯烃生产系统，其包括聚合反应器（例如聚乙烯回路淤浆反应器）和分馏系统，其接收在稀释剂/单体回收系统中处理的反应器流出物，用于再循环至反应器和供应商。导管将包含单体例如乙烯的回流的一部分从分馏系统内转移至聚合反应器，从而向供应商提供较少的单体例如乙烯的排放。因此，单体产率有利地增加，因为返回反应器的单体将单体原料置换到反应器中。回流可以源自设置在分馏子系统中的来自稀释剂再循环塔的冷凝顶灯。稀释剂再循环塔可以接收包含稀释剂和单体的物流作为来自稀释剂/单体回收子系统的进料，并且可以接收回流的非转向部分作为回流。

摘要： A polymerization loop reactor including a loop reaction zone, a continuous takeoff, and a fluid slurry disposed in the reaction zone. A generally cylindrical wall defines the loop reaction zone. The length of the loop reaction zone and the nominal outside diameter of the generally cylindrical wall define a length / diameter ratio greater than 250. The reactor can be charged with a fluid slurry including an olefin monomer reactant, solid olefin polymer particles, and a liquid diluent. The concentration of the solid olefin polymer particles in the slurry can be greater than 40 weight percent based on the weight of polymer particles and the weight of liquid diluent. Also disclosed is a polymerization process carried out by polymerizing, in the loop reaction zone of a reactor as defined above, at least one olefin monomer in a liquid diluent to produce a fluid slurry as defined above.
