Abstract
Abstract The solubilities of carbon dioxide, CO 2 , in a reference semi-synthetic oil and in a developed vegetable-sunflower-based oil for two stroke engines have been measured from 283 K to 348 K and pressures up to 9 MPa in a high pressure gas solubility apparatus that works in isochoric conditions. The densities of the developed vegetable oil from 293 K to 353 K and pressures up to 60 MPa were also measured by using a vibrating tube technique. It was found that the solubility of CO 2 in the vegetable oil is higher than in the reference semi-synthetic oil. The solubility of CO 2 in both lubricants decreases when the temperature increases. In addition, we have found that the solubilities of O 2 in these lubricants are between 7 and 10 times lower than those of CO 2 . Furthermore, PC-SAFT EoS was employed to model the solubility behavior of CO 2 in both lubricants and the goodness of Carvalho and Coutinho model for prediction of CO 2 solubility in low volatile solvents was checked for these lubricants.
