开发了一种名为“MemCal”的关键工具，以支持使用Aspen HYSYS进行膜基气体分离过程的模拟。通过将“MemCal”与模拟器集成，用户可以模拟复杂的多组件/多阶段过程，进行灵敏度研究，并利用默认的HYSYS功能来成本和优化过程。工业上，“MemCal”可用于模拟空气、沼气、天然气、烯烃-石蜡等气体的分离。本文演示了CO2/ ch4二元混合物的分离是“MemCal”的第一个也是最简单的应用。对多阶段工艺的模拟表明，通过优化各阶段间的分离负荷分配，可以降低处理成本。对于CO2/ ch4分离，模拟结果表明，优化后的两阶段工艺加循环的分离成本最小。当采用相当于或优于醋酸纤维素的膜时，发现安装第三级以提高碳氢化合物的采收率是不合理的。
A key tool called “MemCal” is developed to support the simulation of membrane-based gas separation processes using Aspen HYSYS. By integrating “MemCal” with the simulator, users can simulate complex multi-component/multi-stage processes, perform sensitivity studies, and utilize the default HYSYS features to cost and optimize processes. Industrially, “MemCal” can be used to simulate the separation of air, biogas, natural gas, olefins-paraffins and other gases. The CO2/CH4binary mixture separation was demonstrated in this manuscript as the first and the simplest application of “MemCal”. The simulation of various multi-stage processes suggested that the treatment cost can be dropped by optimizing the separation load distribution among the stages. For CO2/CH4separation, the simulations suggested that the optimized two-stage process plus recycle resulted in the least separation cost. The installation of a third stage for boosting hydrocarbons recovery was found unjustified when membranes equivalent to or better than cellulose acetate are adopted.
