Title: Representation of Electrolyte Solution Properties by Means of the Peng−Robinson−Stryjek−Vera Equation of State
Abstract: The Peng−Robinson−Stryjek−Vera equation of state (Stryjek, R.; Vera, J. H. Can. J. Chem. Eng. 1986, 64, 334−340) was used with the Wong−Sandler mixing rule (1992) and the activity coefficient model of Chen et al. (AIChE J. 1982, 28, 588−596) to calculate osmotic coefficients and vapor−liquid equilibrium (VLE) values of electrolyte solutions. The osmotic coefficients calculated by this approach agree with those calculated from the original Chen model. The approach was also used to represent VLE for three ethanol−water−salt systems. The average absolute deviations of the calculated temperatures were around 1 K, and those of the calculated vapor-phase compositions were between 0.01 and 0.02 mole fraction.
