有机蒸气分离膜在乙烯回收中的应用

Application of organic vapor separating membrane in the ethylene recovery

介绍了有机蒸气分离膜的分离原理和膜法乙烯回收装置应用于环氧乙烷／乙二醇装置循环排放气中取得的显著效果．该回收装置实现了节能降耗，大大降低了乙烯的消耗和甲烷的消耗，乙烯回收率高达90％以上．

The separating principle of organic vapor membrane and the application in the ethylene recovery of EO/EG unit tail gas are introduced. By using this process the energy can be reserved, the ethylene and methane consumption decrease, and the ethylene recovery rate exceeds 90 %.
