Abstract
In this work Vidal equation of state formulation (EOS-qE) was evaluated for vapor/liquid equilibria (VLE) isothermal calculations of binary and ternary mixtures, using NRTL model with 2 and 3 parameters for qE representation in the low to high pressure range, resulting at least as convenient and accurate in application as the gamma/phi formulation and Redlich–Kister expansion; and better than using Huron/Vidal and Wong/Sandler mixing rules EOS-GE formulation. Compared with referenced models, satisfactory predictions of VLE at temperatures different than that, at what correlation was obtained. Finally, isobaric VLE was correlated in the experimental error precision range.
