Prediction of Vapor-Liquid Equilibrium Properties for the Mixture of Propylene+Propane from the Combined Use of Peng-Robinson Equation of State and COSMO-RS Model

Xinyun Pu, Lehuan Wu, and Yansheng Liu
Abstract—In this research, the prediction of vapor-liquid equilibrium (VLE) of the binary mixture of propylene+propane from the combined use of the Peng-Robinson equation of state (PR-EOS) and the COSMO-RS model is examined. Following the Van der Waals mixing rule (VdW), the average deviations in both the pressure and vapor phase composition from the method are no more than 0.32% and 0.57%, respectively. Based on the results, it has been shown that PR-EOS+VdW+COSMO-RS is a promising approach for propylene+propane VLE predictions over a wide range of temperatures. This method introduces only one adjustable parameter. Assuming the adjustable parameter as a function of temperature, this method is used as a straight forward process without any iteration to estimate VLE data.

Index Terms—COSMO-RS, Peng-Robinson equation of state, propane, propylene, vapor-liquid equilibrium.
