乙腈法丁二烯装置尾气回收技术改造

Modification of tail gas recovery technology of butadiene plant by acetonitrile process

主要介绍了目前乙腈法丁二烯装置尾气产生和排放情况,结合生产实际,利用现有流程,开展技术改造,对装置产生的尾气进行回收,提高技经指标。

This paper mainly introduces the production and emission of the exhaust gas of the butadiene unit by acetonitrile method.Combining with the production practice,the existing process is used to carry out technical transformation,to recycle the exhaust gas produced by the unit and improve the technical and economic index.
