Abstract
The present invention provides a system for capturing COand/or SO, comprising: (a) a COand/or SOabsorber comprising an amine and/or amino acid salt capable of absorbing the COand/or SOto produce a CO- and/or SO-containing solution; (b) an amine regenerator to regenerate the amine and/or amino acid salt; and, when the system captures CO, (c) an alkali metal carbonate regenerator comprising an ammonium catalyst capable catalyzing the aqueous alkali metal bicarbonate into the alkali metal carbonate and COgas. The present invention also provides for a system for capturing SO, comprising: (a) a SOabsorber comprising aqueous alkali metal carbonate, wherein the alkali metal carbonate is capable of absorbing the SOto produce an alkali metal sulfite/sulfate precipitate and CO.
