Aspen Plus模拟计算甲醇合成的平衡组成

Simulation of Methanol Synthesis Equilibrium Composition with Aspen Plus

采用Aspen Plus模拟软件,对甲醇合成系统中纯组分H2、CO、N2、CO2等的密度值、纯组分甲醇容积值以及不同温度、不同压力下三组分混合物CH3OH-CO-H2容积值进行了计算,在此基础上分别模拟计算了5MPa和15MPa、不同温度下甲醇合成系统的平衡组成。将上述计算值与应用SHBWR状态方程计算值进行比较,结果表明,模拟计算结果与文献值较为接近,误差在工程允许的范围之内,可以用Aspen Plus软件模拟计算甲醇合成系统的平衡组成。

The density of pure H2, CO, N2, CO2; the volume of pure methanol and the volume of three mixers CH3OH-CO-H2 at different temperatures are calculated with Aspen Plus. And then calculate the equilibrium composition of methanol synthesis unit under 5MPa and 15MPa respectively and with different temperatures. The above-mentioned results are also compared with the calculation results of SHBWR .The results illustrate that the simulated data is similar to the reference data, and the errors are within the engineeri...
