Abstract

See full text

The present invention relates to methods for recovering a hydroxide based sorbent from carbonate or another salt by electrochemical means involving separation schemes that use bipolar membranes and at least one type of cationic or anionic membrane. The methods can be used in an air contactor that removes carbon dioxide from the air by binding the carbon dioxide into a solvent or sorbent.
