摘　　要：使用Aspen P1us软件平台,通过用户自定义模块方法,对简化的两步法甲醇制丙烯(MTP)工艺流程包括反应工段、压缩工段和分离精制工段进行了全流程稳态模拟。通过动力学集总模型建立了用户自定义反应模块,模拟了MTP三段绝热固定床反应器内反应物轴向温度分布和浓度分布。通过用户自定义模块与其他内置模块的衔接,嵌入了自定义动力学模型,扩充了模拟范围。在稳态模拟基础上,优化了分离精制工段工艺操作参数,能耗降低约3%,为MTP工艺灵敏度分析和过程强化等提供参考。The total flow simulation and optimization were carried out by means of using user＇ s module on Aspen Plus software for simplifying two-step process of methanol to propylene （MTP）, including reaction, compression and separation reactants were analyzed by estab units. The axial temperature profile and concentration distribution of the lishing user＇ s module based on the lumping kinetics model of MTP reaction. The operating parameters for separation unit were optimized and 3% energy consumption could be saved.
