摘要
利用正构烷烃模型分子法,采用分子量一个参数确定石油窄馏分的基团组成,在实测数据基础上,对UNIFAC基团贡献型饱和蒸汽压模型即Jensen模型参数进行修正,利用文献[1]数据对饱和蒸汽压模型参数修正后,Kikic和Larsen模型预测闪蒸温度的平均相对偏差分别为0.79%和0.79%;汽化率的平均相对偏差分别为7.69%和7.77%,可满足工程计算要求。
With the experimental data, we examine the group contribution method in predicting V-L equilibrium, and the results are not satisfactory. By modifing Larsen model or modifing the parameter in saturate pressure model, we can get the satisfactory results in the predicting of heavy oil V-L equilibrium.
