The objective of this paper is to show the viability of using thermodynamics models of activity coefficients (Wilson, NRTL, UNIQUAC) programmed with matrixes, instead of being programmed with cycles. The vapor-liquid equilibrium relation of mixtures Methanol-Ethanol-Benzene and Acetone-Chloroform-Methanol, represented with residue curve maps and distillation lines maps, was calculated. To obtain better solutions and objectives conclusions, the study was been supported with statistical design of experiments. The matrix programming showed to be faster than the conventional cyclic model, independent of the activity coefficient model used.
