Abstract
The vapor-liquid equilibria (VLE) for the carbon dioxide + octane, and carbon dioxide + decane systems were measured from (322 to 372) K and (319 to 372) K, respectively. The measurements were carried out with a static-type apparatus connected online to a gas Chromatograph. A good agreement was found between the experimental measurements for the studied systems and those reported in the literature at 348 and 344 K for the carbon dioxide + octane and carbon dioxide + decane systems, respectively. Both systems were correlated using the Peng-Robinson equation of state with classical and Wong-Sandler mixing rules. The best VLE representation was obtained using the Wong-Sandler mixing rule with an absolute average deviation less than 1.8 % and 0.0020 mole fraction for pressure and equilibrium compositions, respectively.
