摘　　要：介绍了采用膜分离技术回收乙酸乙烯酯生产中工艺排放气所含乙烯的基本原理,对渗透／残余比、放空量、温度、乙烯回收率等工艺参数进行了优化,乙烯回收率达到56％,经济效益和社会效益显著。This paper introduced the basic principle of ethylene recovery from the vent gas of vinyl acetate plant with membrane separation technology, and optimized the process parameters like permeate/residue ratio, the flowrate of inert purge stream, temperature, and ethylene recovery rate. The ethylene recovery rate of 56% was achieved ,which brought notable economic and social benefits.
