The solubility data of methane in sixthteen alkanes, ranging from methane to hexadecane, were studied at higher pressures. Henry抯 constants were gotten by correlating the data of different pressures in the same temperature. It was proved that Henry抯 law was applicable at the pressures studied. Meanwhile, the graphs for Henry抯 constants of methane in alkanes for different temperatures were gotten. The effects of solvent carbon atoms, and structure of alkanes on Henry抯 constant of methane were also studied. The temperature coefficients of Henry抯 constant equation were correlated. A method was proposed to estimate Henry抯 constants of methane in alkanes by using the critical volume of the alkane solvent at given temperature. The above data and calculation methods are helpful for the application of liquefied natural gas.
