Continuous-Phase Equilibrium Problem:  Quadrature Compositional Characterization and Asymptotic Convergence

Abstract

In this paper, the authors examine the fluid-phase and solid-fluid-phase equilibrium problems in order to determine whether there is an inherent resistance to the convergence of quadraturebased computations in general for phase equilibrium problems. Our findings suggest that convergence can be expected for fluid-phase equilibria in general. For the less familiar solidfluid-phase equilibrium problem, convergence can depend on the postulated description of the solid phase.
