Process synthesis nonideal mixtures

This tutorial paper is a review of recent advances in the synthesis of ideal and nonideal distillation-hased separation systems. We start hy showing that the space of alternative. separation processes is enormous. We discuss. simple methods to classify a mixture either as nearly ideal or as nonideal, in which case it displays azeotropic and possibly liquid/liquid behavior. 

Yet another topic involves the extension of the synthesis methods to processes with multiple solutes. Here, the impact of concentration on the slope of phase equilibrium Eq. (11.4) may become a factor for highly nonideal solutions at high concentrations. The analysis techniques presented herein can be extended when the slopes of the equilibrium curves can be approximated as constant, independent of mixture composition. Also, the analyses are simplified when the minimum external MSA for the principal solute is capable of removing the other solutes as well (El-Halwagi and Manousiouthakis, 1989).
