TERNARY LIQUID-LIQUID PHASE-BEHAVIOR BY DECORATED-UNIQUAC

To investigate the applicability of the decorated-UNIQUAC model for mu lticomponent 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 lim ited and more complicated than that of UNIQUAC without disagreement wi th experimental observations on the progressional behavior of tie line s. The binodal predictions were found very sensitive with respect to t he model parameters, as expected in condensed phases. The general feat ures of non-island type of ternary LLE were excellently reproduced by the decorated-UNIQUAC.
