Mathematical modelling of vapor-liquid equilibrium in system of products of propylene oxide synthesis in a methanol medium

Abstract

Comparison of literature and calculated data on vapor-liquid equilibrium for systems formed by products of propylene oxide synthesis was carried out. On the basis of models NRTL and UNIQUAC the literature data on vapor-liquid equilibrium for the investigated systems were optimized. The values of model parameters and their deviations were estimated. The corresponding phase diagrams were calculated and plotted.
