ABSTRACT

The solubility of CO2 in the systems of CO2 + benzene, CO2 + n-hexane, and CO2 + toluene was meticulously measured at (293.15, 298.15, and 308.15) K and different pressures using a pressure-volume-temperature (PVT) apparatus. Also the effect of pressure on the solubility of CO2 in the organic solvents used in this work was investigated. The Peng-Robinson equation of state (PR EOS) with only one temperature-independent binary interaction parameter was used in correlating the experimental data. The results showed that the PR EOS can accurately correlate the experimental data for the solubility of CO2 in the organic solvents at high pressure. In case of the systems CO2 + benzene and CO2 + n-hexane at 298.15 K, the experimental results obtained from the PVT apparatus were compared with those reported in the literature. The comparison showed that for such systems the results are in good agreement with those of previously published experimental data.
