摘要
针对聚丙烯装置回收丙烯尾气资源工艺剩余大量低浓度烯烃,采用有机蒸气膜法回收系统,使低浓度的烯烃得以富集回收,有效降低聚丙烯装置丙烯单耗,提高了装置的整体经济效益。该工艺先进可靠,节能且环保。
Membrane process for organic vapor recovery is adopted to realize concentration and recovery of low concentration olefins,effec- tively reduce the consumption of propylene in polypropylene unit,and improve the overall economic benefit of the unit.
