Abstract

A simple method is proposed to determine the Wilson constants from binary vapor-liquid equilibrium data. The method is based on a polynomial description of the variation of G^E/RT with composition and finding the maximum value of the curve. The constants are determined by using a hand scientific calculator or a personal computer. Prediction of vapor compositions is as good or better than that obtained by complex optimization techniques.
