| 摘 要： | 基于基团贡献法的思想,本文采用改进的SRK状态方程和修正的MHV1混合规则,将UNIFAC基团贡献法扩展用于HFC HC二元混合物气液相平衡性质的描述,给出了基团划分表和基团间的相互作用参数,使用该方法可以较好地再现HFC HC二元混合物的气液相平衡性质,并且具有良好的预测效果.

| Abstract: | Based on the group contribution theory,the UNIFAC group contribution method,with modified SRK equation of state and MHV1 mixing rule,were used to describe the vapor-liquid equi- librium for HFC HC binaries.Group assignments and interaction parameters between groups for the binary mixtures were presented.The method can precisely represent experimental data of vapor-liquid equilibrium for HFC HC systems,and has well performance in prediction. |
