AbstractThis paper reports measurements of the solubility of water in liquid and supercritical fluid mixtures of dimethyl ether and carbon dioxide. The measurements were made by extracting water under saturation conditions using premixed liquid dimethyl ether-carbon dioxide mixtures. Results are reported for temperatures of 313.8. K and 333.3. K at 9.0. MPa and 15.0. MPa. Results are fitted to the Peng-Robinson cubic equation of state with mixing rules according to Wong and Sandler, using binary interaction parameters fitted to the literature data for the respective binary systems: dimethyl ether-water; dimethyl ether-carbon dioxide; and carbon dioxide-water. Liquid densities for dimethyl ether-carbon dioxide mixtures, measured using a coriolis flow instrument, are also reported. © 2010 Elsevier B.V.
