Calculation of Vapor Liquid Equilibrium and Excess Enthalpy With the Uniquac Equation

Multi-criteria optimization for parametrizing excess Gibbs energy models

“…A well-known example is that the simultaneous description of vapor-liquid equilibria (VLE) and liquid-liquid equilibria (LLE) with G E -models often yields only poor results [3][4][5][6][7]. Also difficulties in describing both excess enthalpy and phase equilibrium data have been reported [8][9][10][11][12]. Hence, the task of describing different data sets with a G E -model is often a multi-criteria optimization (MCO) problem with conflicting objectives.…”
