Abstract

To investigate the applicability of the decorated-UNIQUAC model for multicomponent multiphase liquid mixtures, equilibrium calculations were carried out for a variety of model ternary systems, and some typical predictions were introduced. The predicted phase behavior was less limited and more complicated than that of UNIQUAC without disagreement with experimental observations on the progressional behavior of tie lines. The binodal predictions were found very sensitive with respect to the model parameters, as expected in condensed phases. The general features of nonisland type of ternary LLE were excellently reproduced by the decorated-UNIQUAC.
