摘要
应用膜分离技术,回收聚丙烯装置排空不凝气中的丙烯,回收率在85%以上。在原有丙烯回收的基础上,只需增加膜分离回收系统,每天可多回收2～4t丙烯,可以在短期内收回投资。
Propylene recovery at a rate above 85% from the non-condensable gas released from polypropylene plant was carried out with membrane separation technique. Additional 2-4 tons of propylene could be collected per day with the membrane recovery system equipped on the existing plant. The investment for the innovation could be recouped in a very short term.
