摘要：
A generalized approach for the calculation of complex chemical and phase equilibria is presented which is based on the simulation of the dynamic evolution of a mixture from arbitrary nonequilibrium initial composition towards the final equilibrium composition. The proposed method is able to deal with pure chemical or pure phase equilibria as well as with simultaneous chemical/phase equilibria. The unique advantage of our approach, compared to conventional equilibrium calculations, is the fact that the simulation algorithm always converges towards the thermodynamic equilibrium state regardless which initial composition is chosen.
