An algorithm to identify vapor-liquid-liquid equilibria of binary mixtures from vapor-liquid equilibria
Ian Bell, Ulrich Deiters, Andreas Jaeger
In this work, we demonstrate that tracing the vapor–liquid equilibria for binary mixtures also includes all the information needed to obtain the three-phase line if one is present. This simple observation serves as a launching point for calculation of the liquid–liquid equilibrium and three-phase equilibria, even when one component is supercritical. We close with the demonstration of the automatic construction of an isothermal pressure–composition figure, a capability enabled by solving for the three-phase state. The scripts in the Supporting Information demonstrate in detail how the method is applied.
