Abstract: A process is disclosed for reversibly absorbing acid gases from gaseous mixtures wherein a salt hydrate is heated to a temperature above its melting point and exposed to an acid gas which is absorbed by the salt hydrate to form a salt hydrate melt. This melt is thereafter cooled to a temperature sufficient to solidify the melt and to desorb the acid gas from the solidified salt hydrate. Preferred salt hydrates include tetramethylammonium fluoride tetrahydrate and tetraethylammonium acetate tetrahydrate.

Abstract: The present invention is a membrane and a process for separating at least one component from at least one other component in a gas mixture. A gaseous mixture is passed over a membrane having a thin film of a molten salt hydrate which is selectively permeable to at least one component in the gaseous mixture.

Abstract: Acid gases are separated from a gas stream by bringing the gas stream into contact with a multilayer composite membrane comprising a nonselective polymeric support layer and an active separating layer comprising a polyelectrolyte polymer which contains cationic groups which are electrostatically associated with anions for which the pK.sub.a of the conjugate acid is greater than 3.
