Modeling of Isobaric Vapor-Liquid Equilibrium Data for Ionic Liquid-Containing Ternary Systems

The object of this work focuses, on the one hand, on the development of the Wilson model for electrolytes, temperature-dependent parameters, and, on the other, tests the model and its accuracy in the prediction of ternary VLE data from few experimental data points. The experimental data reported in the literature are used to determine the model parameters proposed in this work for the ethanol-water binary system. The obtained interaction parameters are then used for the correlation and prediction of VLE data for five ternary systems composed of ethanol, water and different ionic liquids with different percentages at atmospheric pressure (101.32 kPa). We have made the prediction of ternary VLE data, ionic liquid-containing ternary systems, from temperature-dependent binary interaction parameters, adjusted by using some ternary VLE data coupled with binary VLE data. The obtained results are in good agreement with the data reported in the literature.
