由两元数据预计三元气液平衡

Prediction of Three Phases of Gas-liquid Equilibrium from Binary Phases Data

着重介绍Wilson两参数方程,如何从两元汽液平衡数据来求得两两相互作用的两参数,进而求解三元气液相平衡的计算法。推荐实用的计算两个参数的FORTRAN程序,并举例说明其应用。

In this article, Wilson binary parameter equation and the method of obtaining two parameters, which act to each other, from binary gas-liquid equilibrium data were introduced. The method can be further extended to obtain three phases gas-liquid equilibrium. A practical FORTRAN program to calculate two parameters was recommended, and some examples were used to illustrate the application of the method.
