    • ­Apparatus (202) for olefin polymerization includes a plurality of shell and tube olefin polymerization reactors (202a, 202b), each of which has an olefin polymerization reaction mixture inlet connection and a crude polyolefin product outlet connection (55a, 55b). Each reactor (202a, 202b) is equipped with a recirculation system including a pump (25a, 25b) arranged to circulate a reaction mixture through the tube side of the reactor (202a, 202b) independently of the introduction of olefin polymerization reaction mixture into the reactor (202a, 202b). The apparatus (202) also includes an inlet reaction mixture distribution manifold (215, 15a, 15b) and an outlet polymerization reaction mixture collection manifold (255, 55a, 55b) interconnecting the reactors (202a, 202b) for operation in parallel. The apparatus (202) also includes catalyst composition and catalyst modifier inlets (16a, 16b, 30a, 30b) for each reactor (202a, 202b) arranged such that a catalyst modifier to may be introduced into each reactor (202a, 202b) at a rate which is independent of the introduction of catalyst composition. The apparatus (202) further incorporates a crude polyolefin product catalyst removal and wash system including a plurality of settler vessels (302, 306, 308), associated piping and an inlet (318) for a catalyst killing agent. This crude polyolefin product catalyst removal and wash system operates to receive crude polyolefin product from the crude polyolefin product outlet (255) and remove residual catalyst therefrom.
    • 用于烯烃聚合的设备(202)包括多个壳管式烯烃聚合反应器(202a,202b),每个反应器具有烯烃聚合反应混合物入口连接和粗聚烯烃产物出口连接(55a,55b)。 每个反应器(202a,202b)配备有再循环系统,其包括泵(25a,25b),泵(25a,25b)布置成使反应混合物循环通过反应器(202a,202b)的管侧,而不管将烯烃聚合反应混合物引入 反应器(202a,202b)。 装置(202)还包括入口反应混合物分配歧管(215,15a,15b)和与反应器(202a,202b)相互并联操作的出口聚合反应混合物收集歧管(255,55a,55b)。 装置(202)还包括用于每个反应器(202a,202b)的催化剂组合物和催化剂改进剂入口(16a,16b,30a,30b),其布置成使得可以在一个反应​​器(202a,202b) 速率与引入催化剂组成无关。 装置(202)还包括粗聚烯烃产物催化剂去除和洗涤系统,其包括多个沉降器容器(302,306,308),相关联的管道和用于催化剂杀死剂的入口(318)。 该粗聚烯烃产物催化剂去除和洗涤系统用于从粗聚烯烃产物出口(255)接收粗聚烯烃产物并从其中除去残留的催化剂。
