ABSTRACT
In this work, the (vapor + liquid) equilibria (VLE) data of the {trifluoroiodomethane (CF3I) + carbon dioxide (CO2)} system was measured at (243.150, 253.150, 263.150 and 273.150) K. The uncertainties of the temperature, pressure and composition were estimated to be less than +-5 mK, +-0.0013 MPa and +-0.005, respectively. PR vdW model and PR HV NRTL model were used to correlate the experimental data. Both models can give satisfied results. This work will supply essential data for (CF3I + CO2) gas mixture using in the gas insulated switchgear (GIS) and gas insulated transmission line (GIL).
