The models/thermodynamics.a4l ASCEND code provides methods for calculating vapor-liquid equilibria (VLE).

Details on various group-contribution methods can be found here:

modified UNIFAC: A modified UNIFAC group-contribution model for prediction of phase equilibria and heats of mixing

The predictive Soave-Redlich-Kwong (PSRK) equation of state combines the Soave-Redlich-Kwong cubic equation of state with the Mathias-Copeman equation and the modified UNIFAC group-contribution method:
