Abstract


This work experimentally investigated the solubility and miscibility of Propylene (R-1270) and Dimethyl Ether (R-E170) in polyalkylene glycol (PAG) oil. The solubility experimental data were used to fit different local composition models from the literature, the Wilson and Heil equations, and the Non-Random Two-Liquid (NRTL) model. A new empirical correlation decreased the average deviation between experiments and the models. Furthermore, the developed correlation was used to compare the solubility of Propylene and Dimethyl Ether (DME) with the solubility of Propane (R-290). At the same conditions, Propane showed the lowest solubility while DME was the highest. The relative difference between the solubility of refrigerants increases at higher pressures. While the solubility values between Propane and Propylene are similar, DME has a discrepant behavior when compared to Propane, reaching a difference in solubility of more than 50 % at a saturation temperature of 60 ◦C.
