摘要

本文作者之一在文献中曾提出了一个通用四参数对应态方程.本文又从分析分子参数与宏观参数之间的基本关系出发

提出了一个包含适用于极性混合物的新的混合法则.使用该方程和此法则相结合的对应态方法

计算了包含由不同种类组分组成的22个二元系统的高压汽液相平衡

泡点压力与汽相成分计算值和文献实验值进行了比较

计算结果有较高的精度.文中还把本方法和LKP、LKWS方法作了比较.

Abstract

A generalized four-parameter equation of state based on corresponding states principle was proposed in a previous paper by Zhang and Xu (1986).In this work

a new mixing rule was derived by analysing the relationship between molecular parameters and bulk properties of fluids. High-pressure vapor-liquid equilibria of 22 binary systems were calculated using the Zhang and Xu equation with the new mixing rule. The calculated pressures and mole fractions of the vapor phase were compared with the experimental values in the literature and also with the results obtained with the LKP corresponding states method. The comparison indicated that the method described here provided better estimates than the LKP method.
