Abstract

The simplified perturbed hard chain theory (SPHCT) was applied to correlate the high-pressure vapor-liquid equilibria (VLE) of binary mixtures containing supercritical carbon dioxide. The SPHCT has an advantage because no critical property for high-boiling component, which is hardly obtained by experiment, is necessary to determine the characteristic parameters. The three characteristic parameters required in the SPHCT can be estimated by using the effective carbon number (ECN). The VLE of binary systems; CO2 + paraffin, CO2 + aromatic compound, CO2 + alcohol and CO2+citrus oil component were studied and the correlation performance of the SPHCT was discussed.
