摘　　要：本文用数学模型借助计算机对一个一次加压二段气体膜分离流程进行研究,得到了上作循环气浓度与流程操作参数之间的关系。用此流程可得到高浓度不易渗透气体的高回收率,同时得到高浓度的易渗透气体。The relationships between the concentration of cycle working gas and operating parameters of process that is a one-pressure-stage two-separation-stage membrane system have been studied with the help of a computer using a mathematical model for evaluating the membrane separation performance. Results computed indicate that not only high percentage recovery of high concentration nonpermeate gas but also high concentration of permeate gas were ob tained by this system.
