    Abstract:
    This paper describes the formulation of vapor-liquid phase equilibrium as a linearly constrained minimization problem. It also describes a second minimization problem designed to test for local phase stability. Vectorized unconstrained minimization techniques can be used to solve this pair of constrained minimization problems. The methods of this paper are applied to liquid-vapor equilibria for mixtures both far from and near to the phase boundary. Significant improvements over the standard successive substitution algorithm are demonstrated.
