ABSTRACT
New experimental results are presented for the solubility of methane in two single solvents (hexane and a petroleum benzine) at temperatures of about (273, 283, and 293) K and pressures up to about 10 MPa. The solubility of methane (in terms of moles of methane per kilogram of solvent at given temperature and pressure) is rather similar in both solvents. The experimental results are evaluated to determine Henry s constant and the partial molar volume of methane in those solvents. A thermodynamic model, based on the extended Henry s law, which accounts for interactions in both liquid and gaseous phases, is applied to correlate the experimental results.
