EP2295474A1 Process for recycling product streams separated from a hydrocarbon-containing feed stream. 审中-公开
一种用于回收已经从含烃进料流中分离的产物流的方法

Process for recycling product streams separated from a hydrocarbon-containing feed stream.
摘要：
The present invention relates to a process for recycling product streams that have been separated from a hydrocarbon-containing feed stream comprising olefin monomer, olefin co-monomer, hydrocarbon diluent and components such as H 2 , N 2 , O 2 , CO, CO 2 , and formaldehyde. In accordance with the present process a hydrocarbon-containing feed stream is separated into a) a first side stream comprising hydrocarbon diluent and olefin monomer; b) a second side stream which is substantially hydrogen-free and comprises hydrocarbon diluent and olefin monomer, c) a bottom stream comprising substantially olefin-free hydrocarbon diluent, and d) an overhead vapor stream comprising olefin monomer, hydrocarbon diluent and components such as formaldehyde, H 2 , N 2 , O 2 , CO and CO 2 , The present process further includes recycling said first and said second side streams in a polymerization process for preparing bimodal polyolefin.
摘要（中）：

本发明涉及一种用于回收产品流thathave是来自含烃进料流中分离包含烯烃单体，烯烃共聚单体，烃稀释剂和组件：如H 2，N 2，O 2，CO，CO 2 和甲醛。 在本处理的含烃进料流被分离成雅舞蹈a）第一侧流包含烃稀释剂和烯烃单体; b）第二侧流基本上无氢和包含烃稀释剂和烯烃单体，c）一种塔底物流，其包括塔顶蒸气流的基本上不含烯烃的烃稀释剂，以及d）包含烯烃单体，烃稀释剂和组件：如 甲醛，H 2，N 2，O 2，CO和CO 2，本方法包括回收进一步表示第一和第二侧，所述用于制备双峰聚烯烃的聚合过程流。
