摘　　要：处理含有亨利组分的相平衡计算。当选用NRTL模型计算时,需对轻组分如H2、O2、N2、CH4、N2O、CO2、CO、Ar、H2S、SO2、NO等特殊处理,设为亨利组分。对于亨利组分和重组分(溶剂)分别建立相平衡计算式,求取其K值,进而计算气液相组成,最后与Aspen Plus软件计算结果比较。结果表明该模型计算结果与Aspen plus软件计算结果相比气液相组成绝对误差很小,计算精度较好,可用于处理含有亨利组分的相平衡计算。Phase equilibrium calculations with henry components are dealt with. When the NRTL model was elected with calculation, light components such as H2, O2, N2, CH4, N2O, CO2, CO, Ar, H2S, SO2 and NO must be processed specially. They are set as henry components. Phase equilibrium calculation formula is set up for henry components and heavy components （solvent） respectively, calculating the K value, calculating gas and liquid phase composition. In the end the calculation results are compared with Aspen plus software. The results show that the model calculation results compared with Aspen plus software are that absolute error of gas and liquid composition is very small. Calculation accuracy is better. So it can be used for phase equilibrium calculation with henry components.
