ABSTRACT

Vapor-liquid equilibrium (VLE) property measurements Page 2 of 25 for 2,3,3,3-tetrafluoroprop-1-ene (HFO-1234yf) + butane (HC-600) were carried out. The range of temperature is from 283.15 K to 323.15 K, and the corresponding range of pressure is from 0.148 MPa to 1.30 MPa. The experimental uncertainties in pressure, temperature, and mole fraction are estimated within 0.5 kPa, 5 mK, and 0.003, respectively. Peng-Robinson (PR) equation of state coupling with Wong-Sandler (WS) mixing rule and van der Waals (vdW) mixing rule were used to correlate the experimental VLE data of HFO-1234yf/HC-600. Both the two models reproduce the VLE property of HFO-1234yf/HC-600 with high accuracy, and PR-WS-NRTL model gave slightly more accurate VLE calculations. Azeotropic behavior was found at high mole fraction of HFO-1234yf.
