Abstract

A numerical scheme has been developed for the solution of equations of state for the prediction of multiphase equilibria. The scheme is applied to a thermodynamic model which employs a modified version of the Peng-Robinson equation for all phases except the water phase. The Henry's constant approach is used for computation of solute fugacities in the water phase. The numerical scheme makes ″optimum″ use of first and second order iterative schemes and circumvents the problems reported by previous investigators. An outline of the scheme is presented with reference to other sources where complete details are available. Examples of two-, three- and four-phase separating are presented to demonstrate the robustness of the proposed scheme. Limited comparison with experimental data is also provided.
