The bubble point pressures of (carbon dioxide + benzene), (carbon dioxide + methylbenzene), (carbon dioxide + n -hexane), and (carbon dioxide + n -heptane) have been measured at CO 2 mole fractions ranging from 0.502 to 0.91 and at temperatures in the range (293.15 to 313.15) K using a pressure−volume−temperature (PVT) apparatus. Also, the effect of temperature and CO 2 concentration on bubble point pressure was investigated. The Peng−Robinson equation of state (PR EOS) with only one 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 bubble point pressure.
