    Resumen

    Efficient and robust methods for phase determination in multiphase-multicomponent equilibrium are key tools for chemical processes simulation. The most widely used methods for equilibrium calculations are generally based on Gibbs free energy minimization or on simultaneous solving of the material balance and equilibrium equations. Both techniques exhibit numerical challenges due to the involvement of highly nonlinear functions/equations and their efficiencies depend on initialization procedures since the number and type of phases present are not known a priori.
