Gas-Liquid Equilibrium Prediction of Ternary System (CO2-Ethanol-Water) at Moderate Pressures and Different Temperatures Using SRK-EOSKeywords: Gas-Liquid Equilibrium, Moderate Pressure, Mixing Rules, SRK-EOS Abstract: In this work, a thermodynamic model for the prediction of gas-liquid equilibrium at moderate pressures (up to 6 bar) and different temperatures (288-323 K) for the ternary system of carbon dioxide (1)-(2) mixture (ethanol-water) is established using Soave/Redlich/Kwong equation of state (SRK-EOS). Two different mixing rules were used to show the effect of the type of mixing rule. A comparison of experimental phase equilibrium data in the literature with the predicted results showed very good representation for one mixing rule and good for the other.
