MULTICOMPONENT SYSTEMS WITH THREE-PHASE SPLITTING REGION

Abstract

A review of scientific publications that describe systems with a three-phase splitting region is presented. Mechanisms of a three-phase splitting region formation are shown. All the suggested classifications of diagrams with a three-phase splitting region are presented. Methods for studying the evolution of a three-phase splitting region are described. Problems connected with the mathematical modeling of liquid - liquid - liquid equilibrium are considered. The ability of mixtures to form three-phase splitting regions and opportunities of separating such mixtures by special methods is analyzed. A list of known systems with three and more liquid phases is presented.
