Abstract

The critical properties of 75 binary systems have been correlated by use of a modified two-parameter Wilson equation. The great advantage of using the Wilson equation is that its generalization to multicomponent systems is straightforward and requires binary parameters only. Extensive tables of binary parameters are given in this work. Comparisons between experimental and predicted critical properties for 61 multicomponent systems are shown. The new method is accurate, it is simple to use, and it requires considerably less computational effort than rigorous methods which solve the equations for the Gibbs criteria at the critical point.
