A new cubic EoS is proposed for the modeling of methanol-hydrocarbons mixtures.
This EoS enables the simultaneous prediction of LLE, VLE and hE.
It is based on the EoS/GE approach and it is totally predictive.
The EoS excess Gibbs energy accounts for the self-association of methanol.
Satisfactory predictions of phase equilibria and excess enthalpies are obtained.
