摘　　要：采用膜分离技术对中国石油兰州石化公司气相法聚乙烯装置的脱气回收系统进行了改造。结果表明,膜分离系统投用后,1-丁烯和异戊烷回收率均大于70%,二者单耗分别降低了0.631%,44.510%,装置改造效果显著。The degassing- recovery system was revamped by membrane separation technology in the gas phase process polyethylene unit of Lanzhou Pet- rochemical Company. The results showed that after the membrane separation technology was applied to the recovery system, both the recovery rates of 1 -butene and isopentane were more than 70% , and the unit consumption of 1 - butene and isopentane was reduced by O. 631% ,44.510% respectively.
