The water contents of compressed methane gas in equilibrium with water and diethylene glycol-water solutions of 0.156, 0.472, and 0.662 mole fraction water were measured at 298.15 and 323.15 K and pressures of 3, 5, and 8 MPa. The solubilities of methane in the diethylene glycol, water, and diethylene glycol-water solutions were also measured under the same conditions of the water content measurement. The methane solubility data were analyzed with the Krlchevsky-Kasarnovsky equation to obtain the Henry constant of methane in the diethylene glycol-water solutions.
