The mixture of physical solvents and alkanol amines as hybrid solvents are a new class of solvents that are used in the sweetening industry of natural gases (C1 and C2) and condensed gas (C3 and C4). In order to have a physical solvent with a very high efficiency as a medium for chemical reactions and separation of gases, it is necessary to have accurate information about the solubility and diffusion coefficient of gases in them. In this study, the experimental method of measuring the solubility and diffusivity of propane gas in sulfolane was carried out in detail and based on the available materials, the isochoric saturation methods for measuring solubility and the infinite volume method for measuring the diffusivity were selected. The obtained results show that the solubility and diffusivity of propane gas in sulfolane decrease and increase, respectively, with increasing temperature. Then, the solubility data were modeled and correlated with the Ping-Robinson-Stergic-Veira with the Panagiotopolous-Reid mixing rule. Correlation results of experimental pressure data with the above model show respectively, 2.30% and 7.07% average and maximum error.
