摘　　要：针对聚丙烯装置中丙烯回收过程,通过理论推导和HYSYS模拟,探讨了压缩冷凝膜分离(CCM)工艺中膜分离系统对原有压缩冷凝(CC)工艺中的气柜系统、压缩系统和冷凝系统的影响。通过气柜中丙烯质量衡算确定了气柜内丙烯浓度随气柜内气体体积减少而降低,在此基础上,确定了膜分离系统循环渗透气对压缩和冷凝系统的影响。针对膜系统对其他系统的影响,提出了调节控制CCM工艺的措施,并对实际生产中遇到的季节变化、膜性能变化、不凝气累积等问题提出了解决方案。The purpose of this paper is to investigate the effects of membrane separation on the other systems such as gas tank,compression, and condensation system for propylene recovery in compression/condensation/membrane process （CCM）. Propylene concentration decreases with the decrease of gas volume according to mass balance in gas tank system. On this basis, the effect of the circular permeable gas on the compression and condensation systems is analyzed by theoretic analysis and HYSYS simulation. Strategies for controlling CCM process are raised and solutions to frequently noted practical problems such as seasonal variation, membrane leaking and non-condensed gas accumulation are suggested.
