本文应用吉布斯—杜亨方程对五个二元系13条等温线的加压汽液平衡数据进行了热力学一致性分析。MH(81)状态方程被用来计算汽相逸度系数和液体摩尔体积,其余全部用实验数据进行计算分析。本文还提出了E值分析法。对其中的三个二元系9条等温线的实验数据进行热力学一致性分析。该方法不用状态方程,单凭实验数据就可以进行整体和逐点的分析评价。两种方法的分析结果基本上是一致的。
In this paper, the Gibbs-Dogen equation was used to analyze the thermodynamic consistency of the vapor-liquid equilibrium data of 13 isotherms of five binary systems. The equation of state for MH (81) is used to calculate the vapor phase fugacity coefficient and the liquid molar volume, and the rest is calculated and analyzed using experimental data. This article also proposed the E value analysis. The thermodynamic consistency analysis of the experimental data of nine isotherms of three binary systems was carried out. The method does not use the state equation, the experimental data alone can be carried out overall and point by point analysis and evaluation. The results of the two methods are basically the same.
