摘要
用ＰＲ方程模型（ＰＲ１）、修正了混合规则的ＰＲ方程模型（ＰＲ２）以及基团贡献状态方程模型（ＧＣ－ＥＯＳ），分别计算了超临界丙烷－乙醇－水体系的二元汽液相平衡数据结果表明：ＰＲ２和ＧＣ－ＥＯＳ模型显示了良好的关联精度，ＰＲ１模型的关联精度欠佳同时，用ＰＲ２和ＧＣ－ＥＯＳ模型能较好地关联该体系的三元汽液相平衡数据。
The PR,modified PR equation and group contribution equation of state (GC-EOS) model were used to calculate the binary vapor-liquid equilibrium data for a propane-ethanol-water system.The good agreements with experimental data were obtained by the PR2 and GC-EOS model,but the inaccurate result was got from the PR1 model.For this ternary system ,both GC-EOS and PR2 model gave the more accurate estimation.It was proved that GC-EOS model was the most practicable one for the C 3H 8-C 2H 5OH-H 2O ternary system.
