摘　　要：以国内某煤化工企业为实例,应用Aspen Plus工业系统流程软件对HT-L粉煤气化合成甲醇工艺中CO变换反应进行模拟,应用RK-SOAVE和ELECNTL的物性方法计算在特定条件下经过变换反应后CO含量.计算结果显示:在设定温度为210℃,压力为3.6MPa的条件下,CO变换反应前后CO气体的摩尔分数由69.578%降为19.700%,此时符合后续合成甲醇工艺条件的要求;同时与实验结果相比,提出模型能很好地模拟CO变换反应.In this paper,CO shift reaction which is a section of the methanol synthesis process using the HT-L pulverized coal gasification is simulated by Aspen Plus industrial systems flower software,which is based on a domestic coal chemical industry.The content of CO after shift reaction is investigated by RK-ASPEN and ELECNTL physical property methods under the given conditions.The computational results show that the molar content of CO decreases to 19.700% from original 69.578% under the given temperature of 210 ℃ and pressure of 3.6 MPa,and which is suit for the requirement of methanol synthesis process.At the same time,compared with the experimental data,the present model can simulate the CO shift reaction very well.
