  • Method and system for capturing carbon dioxide and/or sulfur dioxide from gas stream
    Patent number: 8771403
    Abstract: The present invention provides a system for capturing CO2 and/or SO2, comprising: (a) a CO2 and/or SO2 absorber comprising an amine and/or amino acid salt capable of absorbing the CO2 and/or SO2 to produce a CO2- and/or SO2-containing solution; (b) an amine regenerator to regenerate the amine and/or amino acid salt; and, when the system captures CO2, (c) an alkali metal carbonate regenerator comprising an ammonium catalyst capable catalyzing the aqueous alkali metal bicarbonate into the alkali metal carbonate and CO2 gas. The present invention also provides for a system for capturing SO2, comprising: (a) a SO2 absorber comprising aqueous alkali metal carbonate, wherein the alkali metal carbonate is capable of absorbing the SO2 to produce an alkali metal sulfite/sulfate precipitate and CO2.
