摘　　要： 本文针对膜法回收油井气中CO₂时原料气中二氧化碳浓度波动大,渗透气及尾气中二氧化碳浓度控制要求高的特点,采用平推流全混流模型对多级提浓流程进行切割和模拟,并讨论了膜性能及操作压力对过程的影响。文中还用Chueh-Pransnitz公式计算了二氧化碳/甲烷体系的临界温度及临界压力。 In accordance with the charecteristics of membrane separation process of carbon dioxide recoverying from oil-well gas, such as big fluctuation in feed gas concentration, high reqire-ment in concentration control of carbon dioxide in the permeate stream and tail gas,a multistage process is cut and simulated using plug-mixed model,and the effects of membrane performance and operating pressure on the process are discussed. The upper limit of operating pressure is calculated using Chueh-Prausnitz formulas.
