A New Mixing Model for Calculating the Solubilities of Solids in Supercritical Fluids

摘要

A new excess local-composition mixing model (ELC) based on both the thermodynamic excess property concept and local-composition concept was proposed. The solubilities of solids in supercritical fluids for 37 binary systems and 36 ternary systems were calculated by RK equation with the ELC mixing rule. The accuracies of correlation are quite satisfactory.
