摘要

本文提出了一个描述汽液平衡的拟组分模型.作者选取38个恒温二元汽液平衡体系对该模型进行了检验

结果表明:1.在中、低压力范围内

用拟组分模型能够精确地关联二元体系的汽液平衡.其关联精度明显优于UNIQUAC模型.2.拟组分模型适用于各种非理想体系(包括具有恒沸点及存在缔合的体系).

Abstract

For the purpose of precisely correlating the data of vapor-liquid equilibria

the present paper proposes a new model named Pseudo-Component Model. Thirty eight sets of isothermal binary systems were chosen to test the model. The findings are as follows: 1. Under a moderate pressure

isothermal vapor-liquid equilibria of binary systems can be correlated by Pseudo-Component Model

with its correlation precision much better than that of UNIQUAC. 2. Pseudo-Component Model car

be applied to various non-ideal systems

especially it can describe the compositions and pressures of azeotropes rather precisely.
