A useful model, Group-Contribution method based Modified Wilson equation (GC-MW) previously developed, has been extensively adopted to calculate liquid–liquid equilibria (LLE) for quaternary systems consisting of alkane, methanol and aromatics (type I and type II) from pure-component properties alone. Further, its applicability has been evaluated in comparison with UNIFAC widely applied.
