Abstract

Vapor - liquid equilibrium (VLE) of the CO2 + R290 mixture has been measured by the recirculation method. Thirty-three data sets of VLE measurements were obtained in the temperature range between (260 and 290) K and in the pressure range between (408 and 4710) kPa. The experimental uncertainties of the temperature, pressure, and composition measurements are estimated to be within 3 mK, 3 kPa, and 0.11 %, respectively. The present data were compared with the calculation by the REFPROP and correlated well by two cubic equations of state, i.e., the Peng - Robinson equation and the Soave - Redlich - Kwong equation.
