阅读说明：本技术 改进气相聚合的方法 (Process for improving gas phase polymerization ) 是由 B·J·萨瓦特斯凯 B·R·格林哈尔希 J·A·穆巴斯 A·C·麦克金尼斯 R·W·艾默尔曼 于 2020-03-04 设计创作，主要内容包括：本发明的公开内容涉及在气相反应器中使用一种或多种冷凝剂(CAs),和实时计算CA组合物内一类CA对另一CA之比生产聚烯烃的方法。本发明的公开内容提供在聚合烯烃所使用的气相反应器内控制冷凝相冷却的方法。该聚合可使用一种或多种聚合催化剂以聚合一种或多种烯烃单体,且可包括以第一冷凝剂对第二冷凝剂之比引入第一冷凝剂和第二冷凝剂,该比值通过下述步骤计算：确认第一冷凝剂的粘附极限,计算涉及第一冷凝剂和第二冷凝剂的当量因子,确认总体可允许冷凝剂组合物,和计算被移除且被第二用量的第二冷凝剂替代的第一冷凝剂的第一用量。(The present disclosure relates to a method of producing polyolefins using one or more Condensing Agents (CAs) in a gas phase reactor, and calculating the ratio of one type of CA to another CA within a CA composition in real time. The present disclosure provides a method for controlling condensed phase cooling in a gas phase reactor used to polymerize olefins. The polymerization may use one or more polymerization catalysts to polymerize one or more olefin monomers, and may include introducing a first condensing agent and a second condensing agent in a ratio of the first condensing agent to the second condensing agent, the ratio being calculated by: the method includes identifying an adhesion limit of a first condensing agent, calculating an equivalence factor related to the first condensing agent and a second condensing agent, identifying an overall allowable condensing agent composition, and calculating a first amount of the first condensing agent that is removed and replaced with a second amount of the second condensing agent.)
