THEORETICAL DERIVATION AND EXPERIMENTAL STUDIES OF PHASE BEHAVIOR IN TERNARY WATER-SALT SYSTEMS UNDER SUB-AND SUPERCRITICAL CONDITIONS

摘要

Four main types of binary fluid phase diagrams were used as a starting point for derivation of the systematic classification of binary complete phase diagrams by the method of continuous topological transformations. This method and the classification of binary phase diagrams, containing the boundary versions of phase diagrams with ternary nonvariant points, were applied to derive the main types of fluid and complete phase diagrams for ternary systems with one volatile component and immiscibility phenomena in two constituent binary subsystems. Some general conclusions gained from the analysis of derived ternary phase diagrams and the available experimental data are represented.
