In this work, VLE data for binary mixture of carbon dioxide (CO2) + 1, 1-difluoroethane (HFC-152a) were measured at five temperatures of (273.15, 283.15, 293.15, 303.15 and 313.15) K respectively by using a circulation-type equilibrium apparatus in which both vapor and liquid phases were recirculated. The experimental data were correlated with the Peng-Robinson equation of state (PR-EoS) using the Wong-sandler mixing rule combines with the NRTL excess Gibbs free energy model and the CarnahanStarlingDe Santis equation of state (CSD EoS). Almost all the calculated values with this model give good agreement with the experimental data. |
