摘要： An improved polymerization process includes withdrawing a portion of a fluid slurry through a plurality of active continuous take off mechanisms, monitoring the pressure of feed material fed to the reactor, and adjusting the continuous take off mechanisms in response to the monitored feed line pressure.

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 manufacturing system for producing polyolefin includes a polymerization reactor, a flash chamber, and a purge column. In certain embodiments, the purge column may receive a solids stream directly from the flash chamber. Further, the purge column may function as a feed tank for an extruder within an extrusion/loadout system. According to certain embodiments, the manufacturing system may be configured to consume less than 445 kilowatt-hours of energy per metric ton of polyolefin produced based on consumption of electricity, steam, and fuel gas.

摘要： Multiple components are selected, conveyed, and measured in a polymerization system. A control system adjusts the system variables to the desired values. Portions of the components can be fed to a pre-contactor before introduction into the polymerization reactor. The catalyst component concentrations and residence times are tightly controlled in the pre-contactor to affect product properties. The pre-contactor can be a single or multiple combinations of a CSTR or plug flow pre-contactors.
