丁苯装置苯乙烯回收系统改造

Recycling system modification of phenylethylene of butylbenzene device

齐鲁石油化工股份有限公司橡胶厂丁苯装置苯乙烯回收系统,塔底胶乳中残留苯乙烯量控制指标为0.1±0.02%,废水中苯乙烯含量控制指标为200～400ppm,塔的使用周期要求3个月。实际生产中这些指标很难达到。本文介绍了改造后塔底胶乳残留苯乙烯合格率100%,废水中苯乙烯含量合格率100%,塔的使用周期达到3个月的要求。经济效益、社会效益显著。 关键词:苯乙烯回收;使用周期;苯乙烯含量;

Introduced the recycling system of phenylethylene,further presented the qualified rate of the remained phenylethylene at bottom of the tower to reach 100% after modificadtion, the pheyletlylene content of qualified rate in the wast water is 100%,the service life of the tower is 3 monthes. For the economic benefit and social benefit is obvious.
