Abstract

This short communication reports phase equilibrium data (cloud points), employing the synthetic static method, for the system [grape seed oil (GSO) + carbon dioxide (CO2) + ethanol] up to T = 343.15 K and 22.53 MPa. Experimental results were modelled using the Peng-Robinson equation of state with the classical van der Waals quadratic mixing rule (PR-vdW2). It is shown that the thermodynamic model is able to represent satisfactorily the phase behaviour of the system investigated. (C0 2013 Elsevier Ltd. All rights reserved. (AU)
