UNIFAC基团贡献法是目前流行的一种重要的推算汽液平衡的方法,可用以预测化工生产中遇到的许多非电解质液体混合物的活度系数。本文对一百三十三个体系应用UNIFAC 模型在微机上进行了计算,并对该模型的活度系数计算结果与文献实验值作了比较,从而对模型的实际应用作出了估计。
The UNIFAC Group Contribution Method is an impor- tantly popular method for predicting vapor-liquid equilibrium and can be used to predict the activity coefficients of many non-electrolyte liquid mixtures encountered in chemical production. In this paper, the calculation of the UNIFAC model for one hundred and thirty-three systems is carried out on a microcomputer. The calculation of the activity coefficient of the model is compared with the experimental data. The practical application of the model is estimated.
