ABSTRACT

A visual and volume-variable high-pressure phase equilibrium analyzer (PEA) was used for measuring the isothermal vapor-liquid equilibrium (VLE) phase boundaries of CO2 + ethanol and CO2 + acetone at temperatures from (291.15 to 313.15) K over a wide composition range. The isothermal phase equilibrium properties obtained from this work were compared with literature values to clarify the inconsistency of the VLE data taken from different sources. The new VLE data were correlated with the Soave-Redlich-Kwong, the Peng-Robinson, and the Patel-Teja equations of state incorporating with the one-parameter and the two-parameter van der Waals one-fluid mixing rules, respectively.
