VAPOR-LIQUID EQUILIBRIA AND HENRY'S CON-STANTS FOR TERNARY SYSTEMS CONTAINING HYDROGEN AND LIGHT HYDROCARBONS

[摘要] References(13)Cited-By(4)The vapor-liquid equilibria of hydrogen-methane-propylene, hydrogen-ethylene-propane, and hydrogen-propylene-propane ternary systems were measured at temperatures from -100° to -25°C and at pressures from 20 to 80 atm. The experimental results agreed with those calculated by the BWR equation except for temperatures below the normal boiling point of the heaviest hydrocarbon. By using the vapor-liquid equilibrium data obtained, Henry''s constants for hydrogen in binary hydrocarbon solvents were determined. The nonideality of the solvent mixture was small, so that the regular solution theory was successfully applied to Henry''s constants for hydrogen in these mixed solvents.
