Physical Solution. In this type of process the component being absorbed is more soluble in the liquid absorbent than other components of the gas stream, but does not react chemically with the absorbent. The equilibrium concentration of the absorbate in the liquid phase is strongly dependent on the partial pressure in the gas phase. An example is the absorption of hydrogen sulfide and carbon dioxide in the dimethyl ether of polyethylene glycol (Selexol Process). Relatively simple analytical techniques have been developed for designing systems of this type. [Pg.6]
