Abstract
Using fugacity coefficient of a cubic equation of state, Henry’s law constant of a solute in a solvent isincorporated into binary interaction parameter of the classical attractive parameter mixing rule. Thedeveloped equation is a function of temperature. The binary interaction parameter is evaluated by purecomponent critical properties and acentric factors of the solute and the solvent and the Henry’s lawconstant of the solute in the solvent. The developed model accurately describes the solubility of gasesincluding methane, ethane, nitrogen, carbon dioxide and hydrogen sulphide in heavy n-alkanes from lowto high pressure for wide range of temperature. The solubility of methane and carbon dioxide in wateris also predicted adequately.
