Objective functions analysis in the minimization of binary VLE data for asymmetric mixtures at high pressures

JA López, VM Trejos, CA Cardona - Fluid Phase Equilibria, 2006 - Elsevier
Five different objective functions were studied with the purpose of analyzing their
performance for parameters estimation of vapor–liquid equilibrium models for a series of 13
non-polar and 13 polar asymmetric binary mixtures at high pressures. Peng–Robinson
equation of state coupled with the Wong–Sandler mixing rules were used for modeling the
VLE in all cases. The first two objective functions are based on the calculation of the
distribution coefficients for each component in the mixture and the remaining objective …
