Abstract

Phase equilibrium calculations constitute a significant percentage of computational time m compositional simulation, especially as the number of components and phases increase Reduced methods address this problem by carrying out phase equilibrium calculations using a reduced number of independent parameters These methods have shown to speed up flash calculations, decrease simulation times, and also improve convergence behavior In this paper, we present new reduced parameters using the two-parameter binary interaction parameter formula originally proposed by LI and Johns [1] The new reduced parameters are applied to solve twophase flash calculations for five different fluid descriptions The results show a significant reduction in the number of iterations required to achieve convergence compared to the LI and Johns original approach The improved method Is also more robust than all previous reduced methods We also compare computational times with the new reduced approach to conventional flash calculations based on the minimization of Gibbs energy using optimized software.
