摘　　要：分别论述了采用变压吸附法(PSA)和膜分离法回收甲醇合成放空气的特点,对2种回收方法的回收量、回收率和各项技术经济指标进行了对比,结果表明,膜分离技术的有效气体总回收率、惰性气体排放率均高于PSA ,能耗低于PSA。The characteristic for recovering methanol synthesis releasing gas was discussed separately for using pressure shift adsorption(PSA) method and membrane separation method, comparison was made for the recovery quantity, recovery rate, and each technical/economic index for these two kinds of recovery methods, the result indicates that the total recovery rate of the effective gas by membrane separation and the discharge rate of inert gas are higher than PSA, but its energy consume is lower than PSA.

关 键 词：膜分离法 变压吸附法(PSA) 甲醇合成放空气 回收率
