Modélisation des équilibres L-S par un modelé Prédictif base sur le concept de contribution de groupes

Abstract

The main objective of this work consists of the prediction of phase diagrams of liquid-solid equilibria for sixteen binary systems by the GC-NRTL and UNIFAC models. The comparison of these results showed us that the solubilities predicted by GC-NRTL are in very good agreement with those experimental ones whose average absolute relative deviation AAD is equal to 5.3601%, unlike those obtained by UNIFAC whose AAD is 8.3617 %.
