Solubility of various gases in Selexol solvent at 70°F (21°C) as a function of partial pressure � For an ideal system, Henry’s law assumes a linear relation between the solubility of gas component i and its partial pressure, � y i.P = H i.x i � where H i is the Henry’s constant.
HENRY’S LAW � P i = H.X i or X i = (Y i / H).P � This implies that acid gas absorbed in liquid phase (X i) is proportional to its gas mole fraction (Y i) and inversely to Henry’s constant (which is constant for a given temperature). � Much more importantly, the solubility is proportional to the total gas pressure (P). � This means that at high pressure, acid gases will dissolve in solvents, and as the pressure is released, the solvent can be regenerated.
