摘要: Abstract Using fugacity coefficient of a cubic equation state, Henry's law constant solute in solvent is incorporated into binary interaction parameter the classical attractive mixing rule. The developed function temperature. evaluated by pure component critical properties and acentric factors solvent. model accurately describes solubility gases including methane, ethane, nitrogen, carbon dioxide hydrogen sulphide heavy n -alkanes from low to high pressure for wide range methane water also predicted adequately.
