Abstract

Vapor-liquid equilibria of the binary supercritical carbon dioxide (scCO2)+oleic acid, scCO2+palm oil, and scCO2+palm kernel oil were measured at a wide range of temperatures from 333.2 to 373.2K and pressures from 8.5 to 35MPa in a circulation-type phase equilibrium apparatus. The samples from liquid and vapor phases were analyzed using UV-vis spectrometer and a liquid hold-up equipment. The phase equilibrium data were correlated with Peng-Robinson Equation of State (PR-EOS) using Wong-Sandler mixing rule and optimum values of binary interaction parameters were determined. The relative deviation between experimental data and predicted data was in the range of 6.9-8.7%, suggesting that the PR-EOS with Wong-Sandler mixing rule is capable of predicting the vapor-liquid equilibria of oleic acid + scCO2, palm oil+scCO2, and palm kernel oil + scCO2.

N2 - Vapor-liquid equilibria of the binary supercritical carbon dioxide (scCO2)+oleic acid, scCO2+palm oil, and scCO2+palm kernel oil were measured at a wide range of temperatures from 333.2 to 373.2K and pressures from 8.5 to 35MPa in a circulation-type phase equilibrium apparatus. The samples from liquid and vapor phases were analyzed using UV-vis spectrometer and a liquid hold-up equipment. The phase equilibrium data were correlated with Peng-Robinson Equation of State (PR-EOS) using Wong-Sandler mixing rule and optimum values of binary interaction parameters were determined. The relative deviation between experimental data and predicted data was in the range of 6.9-8.7%, suggesting that the PR-EOS with Wong-Sandler mixing rule is capable of predicting the vapor-liquid equilibria of oleic acid + scCO2, palm oil+scCO2, and palm kernel oil + scCO2.
