“…By definition,Henry'sconstant of a gas solute (1) in a hydrocarbonsolvent (2) is given as: In a typical application, we used data acquired at OSU on the solubility of hydrogen, methane,ethane, CO and CO2 in n-paraffins,along with data from the literature,to develop parameter generalizations of both cubic (SILK) and simplified-perturbed-hard-chain-theory (SPHCT) [16] equations of state [12,14,41,42]. These results, illustrated by the methane and CO evaluations in Table X, demonstrate the relative abilities of the two equations of state.…”
