摘要
Phase equilibria and saturated densities were measured at 291.15 K and at high pressures with a static-circulation apparatus for carbon dioxide + ethanol. An experimental apparatus, equipped with Anton Paar DMA 512S vibrating tube density meters, was used in the experiments for phase-separation properties at high pressures. Coexisting phase compositions and the saturated density of each phase were measured up to a maximum temperature of 400 K and a maximum pressure of 20 MPa. The experimental data obtained were correlated with the conventional Soave-Redlich-Kwong (SRK) equation.
