摘要
以Ｃｈｅｎ（１９８６）提出的扩展ＮＲＴＬ活度系数模型为基础，重新应用实验数据将原模型中的固定交互作用参数关联为温度的函数，以ＮＨ３－Ｈ２Ｓ－Ｈ２Ｏ体系的汽液平衡计算为例，将本文修正的模型与其它通用的Ｐｉｔｚｅｒ模型及Ｃｈｅｎ模型的计算结果相比较。
Based on the model of extended NRTL by Chen (1986),modification was made by using experimental data to correct some fixed parameters as function of temperature.By calculating the VLE of NH 3 H 2S H 2O system,we found the calculated results were in good agreement with experimental data in the literature.We also compared the results of modified model with those of other models such as Edwands,Beutier,Chen,et al.
