摘要
概述了近年来汽液相平衡的测定方法:直接法(蒸馏法、静态法、流动法、循环法、泡露点法),间接法(饱和蒸汽压法、沸点仪法)和汽液相平衡计算方法(状态方程法和基团贡献法)的研究现状及其发展趋势,对其进一步的研究做了展望。
The current situation of many experimental techniques and calculation methods used to investigate vapor-liquid equilibrium in recent years was presented in this paper. The experimental techniques are direct sampling method and indirect sampling method. Direct sampling method can be further separated into distillation method, static method, flow method, circulation method, dew and bubble-point method, while indirect sampling method can be further separated into saturated vapor pressure method and ebulliometer. The calculation methods are separated into EOS and UNIFAC. Its prospect was also given in this article.
