Phase behaviour of the pseudo-ternary system carbon dioxide + ethanol + fish oil at high pressures Melgosa Gómez, Rodrigo Sanz Díez, Mª Teresa García Solaesa, Ángela Beltrán Calvo, Sagrario Phase equilibrium Supercritical carbon dioxide Ethanol Fish oilThermodynamic modelling Peng-Robinson equation of state This work provides experimental fluid phase equilibrium data of the pseudo-ternary mixture CO2 + ethanol + fish oil, a system of interest in pharmaceutical and food-industry applications such as the production of omega-3-enriched lipid derivatives at mild, non-oxidative conditions. Experimental tie-lines were obtained by means of an analytical isothermal method with recirculation of the vapour phase. Measurements were carried out in the temperature range 323.15 K–343.15 K and at pressures from 10 MPa to 30 MPa. The Peng-Robinson equation of state coupled with the conventional van der Waals mixing rules with two adjustable parameters was used for experimental data correlation. 2017-12 info:eu-repo/semantics/article 0021-9614 http://hdl.handle.net/10259/4566 10.1016/j.jct.2017.07.032 eng The Journal of Chemical Thermodynamics. 2017, V. 115, p. 106-113 https://doi.org/10.1016/j.jct.2017.07.032 http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Attribution-NonCommercial-NoDerivatives 4.0 International Elsevier
