Vapor-liquid equilibrium (VLE) data for the carbon dioxide (CO2) plus 1,1,1,2-tetrafluoroethane (R134a) system at temperatures from 252.95 K to 292.95 K and pressures up to 2 MPa
Isothermal vapor-liquid equilibrium data of the binary mixture of carbon dioxide (CO2)-1,1,1,2-tetrafluoroethane (R134a) at temperatures between 252.95 K and 292.95 K and pressures up to 2 MPa are measured and correlated. To obtain experimental data, we have used the static-analytic method with liquid and vapor phase sampling. The data are correlated using the Peng-Robinson (PR) equation of state and the classical mixing rules.
