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 + scCO(2), palm oil + scCO(2), and palm kernel oil + scCO(2).
