摘　　要：通过把自行开发的膜分离数学模拟软件嵌入HYSYS,形成了膜分离计算模块(M-100),成功实现对商业化工计算软件进行二次开发.与其它类似软件的对比显示,该模块用于多组分气体膜分离过程模拟时具有较高的可靠性.在此基础上运用该软件对含CO2多组分气体膜分离过程进行了模拟计算.计算结果显示:采用单级膜分离过程,渗透气循环工艺的分离效率高于尾气循环工艺,但能耗较高;采用多级膜分离过程,串联工艺分离产物中CO2的浓度较高,而并联工艺渗透气流量较高,通过串/并联组合可获得较理想的分离效果.HYSYS simulation system is one of the most popular chemical engineering simulation software. It has many merits such as easy to operate, strong function, precise simulation. Self-designed membrane module software was embedded into HYSYS to form a simulation module （M-100）, and the secondary development for this commercial chemical software was successfully carried out. Compared with other simulation results, it exhibited good reliability. The software was applied to simulate the CO2-containing multi-component gas separation process by membrane. The results showed that in a single-stage membrane process the separation efficiency of permeate recycle was higher than retentate recycle but with a higher energy cost. For a multi-stage membrane process, the parallel mode could bring a higher permeation gas flow rate while series mode can get a higher CO2 concentration in the permeate side. Optimal separation performance could be obtained by a parallel/series combined process.
