Abstract
In this work, the PVTx properties of carbon dioxide + 2,3,3,3-tetrafluoroprop-1-ene were measured by an isochoric apparatus. The experiment covered both two-phase and superheated vapor regions and have been performed a total of eight isochores within a temperature range that spanned from (223 to 373) K and within a pressure range from (62 to 2292) kPa. Our experimental results were correlated with the Carnahan–Starling–DeSantis equation of state (CSD EoS) and predicted with REFPROP 9.0. Coefficients for the CSD EoS were derived from the experimental data. Results in the two-phase region showed a good agreement with the CSD equation and a strong disagreement with the REFPROP 9.0. Data in the superheated vapor region were also predicted by extrapolating coefficients for the CSD EoS at higher temperatures. The agreement with CSD EoS for the superheated vapor region experimental data was also good. The vapor–liquid equilibrium (VLE) behavior of the studied binary system from the experimental data was also der...
