摘要
整理了已公开发表的氢氟烃(HFC)/烷烃(HC)二元混合物气液相平衡实验数据,对实验数据进行了热力学一致性检验。采用PR方程加van der Waals混合规则描述该类混合物的气液相平衡性质,优化得到了11种混合物的二元交互作用系数,经比较表明采用优化结果能够高精度再现气液相平衡实验数据,比k_(ij)取0的计算结果有很大改善.
Vapor-liquid equihbrium data for the binary hydrofluorocarbon(HFC)/Hydrocarbon(HC) system were collected,and thermodynamic consistency test was performed.The binary interaction parameters for 11 kinds of these systems were fitted to the experimental VLE data using PR equation of states together with the van der Waals mixing rule.Comparison showed that VLE properties could be represented much better with the optimized binary interaction parameters than merely taking k_(ij)=0.
