The investigations presented show that electrodialysis with alternating bipolar and anion-exchange membranes can be used for low-temperature regeneration of aqueous monoethanolamine- (MEA) based sorbents in gas purification systems not intended for a high degree of CO/sub 2/ removal from gases, when complete decarbonization of the sorbent is not needed. Independent use of this type of electrodialyzer in systems for a high degree of CO/sub 2/ removal is restricted by mass transfer through anion-exchange membranes in weakly carbonated MEA solutions.
