vapour liquid equilibria of fluoromethane Tetrafluoromethane at the temperature 130 46 k
The Journal of Chemical Thermodynamics, 1998Co-Authors: I.m.a. Fonseca, G G Sardinha, Lelio Q LoboAbstract:Abstract The total vapour pressure of binary liquid mixtures of (fluoromethane+Tetrafluoromethane) has been measured at the temperature 130.46 K. Two partially miscible liquid phases were found. The excess molar Gibbs energy was calculated in the region where the two liquids are mutually soluble. For the hypothetical equimolar mixture, G E m 01 ( x =0.5)=846 J mol −1 .

investigation on vapor liquid equilibrium for strongly zeotropic ternary mixture of 2 3 3 3 tetrafluoroprop 1 ene r1234yf trifluoromethane r23 Tetrafluoromethane r14
International Journal of Heat and Mass Transfer, 2017Co-Authors: Yanbin Qin, Zilong Wang, Hua ZhangAbstract:Abstract The cubic equation of state/excess Gibbs free energy ( CEoS / G E ) model is a new idea to predict non-ideal systems. In this study, the Peng-Robinson (PR) EoS combined with the Wong-Sandler (WS) mixing rule and the modified UNIFAC group contribution activity model was used to calculate the vapor liquid equilibrium (VLE) data. The average absolute relative deviations (AARD) of pressure and the average absolute deviations (AAD) of the vapor phase mass fraction between the calculated results and experimental data are 0.87% and 0.005 for fluoroethane (R161) + 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) over the temperature range of (283.15–323.15 K) and at pressures varying from 0.4 MPa to 1.8 MPa, respectively. The liquid and vapor phase mass fraction deviations are within ±0.028 and ±0.025 for difluoromethane (R32) + pentafluoroethane (R125) + 1,1,1,2-tetrafluoroethane (R134a) system at temperatures of (205–350 K), respectively. The VLE behavior for the strongly-zeotropic mixture of 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) + trifluoromethane (R23) + Tetrafluoromethane (R14) which is suitable for the three-stage auto cascade refrigeration system was calculated at pressures of (0.2–2.2 MPa) and the corresponding three-dimensional phase diagrams were constructed. It was found that the sliding temperature increases with the decrease of pressure and the maximum predicted sliding temperature reached 73 K.
