The reliable prediction of liquid- liquid equilibrium (LLE) plays an important role for many kinds
of separation technologies. In this work, predictions of Liquid- Liquid Equilibria (LLE) for three
binary mixtures at 0.1 MPa have been done using the equations of state-excess Gibbs energy
model (EoS-GE). The Peng–Robinson EoS modified by Stryjek and Vera (PRSV), and two mixing
rules, MHV1 and MHV2, with UNIQUAC model have been applied to three binary systems
including Nonane+Methanol, MethylCyclohexane+Methanol and Phenol+Hexane. The interaction
parameters of UNIQUAC GE model have been optimized for these three binary systems from LLE
data. The MHV2 excess Gibbs mixing rule shows more reliable agreement with experimental data.
