Abstract A new method for phase equilibrium calculation has been proposed in subregular solution model based on the concept of equality of two-phase equilibrium criterion of both the effective chemical potential and the grand potential. Comparing with the optimization for minimum free energy, it seems to be simpler in calculation and no more convergence problem.

Key words: subregular solution model phase equilibrium grand potential
