Abstract
Isothermal-vapor-liquid equilibrium data of the rapeseed oil-carbon dioxide system were measured with a vapor-recirculation apparatus at 313.15, 333.15, 353.15, and 373.15 K at pressures between 10 and 85 MPa. The solubilities of rapeseed oil in carbon dioxide were compared with solubility data of other vegetable oils from the literature. A lattice model equation of state (EOS) is used to describe the rapeseed oil-carbon dioxide system. The lattice EOS was improved by introducing a more accurate EOS for carbon dioxide (Bender EOS) into the model. With the Kumar-Bender model and a tree-binary-parameter, composition- and density-dependent combining rule proposed by Wilczek-Vera and Vera, a quantitative description of phase equilibrium is obtained. The temperature dependence of the binary parameters has been evaluated for interpolation or extrapolation purposes.
