چکیده انگلیسی
In this paper, bubble point pressures and saturated liquid densities of {2,3,3,3-Tetrafluoroprop-1-ene (R1234yf)â¯+â¯propane (R290)} binary mixtures were measured using a compact single-sinker densimeter. Measurements were carried out over temperatures from (255.048 to 300.135)â¯K and mole fractions of R1234yf at (0.113, 0.217, 0.322, 0.422, 0.533, 0.625). The experimental standard uncertainties were estimated to be less than 5â¯mK for the temperature, 2â¯kPa for the pressure, 0.003 for the mole fraction and 0.02% for the density. The experimental bubble point pressures were correlated by the Peng-Robinson equation of state, while the experimental saturated liquid densities were represented with the VDNS and our modified Rackett equations. In addition, saturated liquid densities of azeotropy point at temperatures Tâ¯=â¯(253.150, 263.150, 273.150, 283.150 and 293.150)â¯K were determined based on our previous and present work.
