Prediction of Vapor-Liquid Equilibrium of Polypropylene Oxide Solution Systems by Cubic Equations of State

Hajir Karimi, Mahmood Reza Rahimi, and Ebrahim Ahmadloo
Abstract—In this research, vapor-liquid equilibrium behavior of Polypropylene oxide (PPO)/solvent and Polypropylene glycol (PPG)/solvent were calculated using cubic equation of states. Eight models containing PRSV and SRK CEOS with four mixing rules namely vdW1, vdW2, Wong-Sandler (WS), and Zhong-Masuoka (ZM) were applied to calculations of bubble point pressure. For the better prediction, the adjustable binary interaction parameters existing in any mixing rule were optimized. The results of absolute average deviations (%AAD) between predicted and experimental bubble point pressure were calculated and presented. The PRSV+vdW2 model was the best predictive model with the highest accuracy (AAD=1.021%) between other models.
