  • AQUEOUS CO2 ABSORBENT COMPRISING 2-AMINO-2-METHYL-1-PROPANOL AND 3-AMINOPROPANOL OR 2-AMINO-2-METHYL-1-PROPANOL AND 4-AMINOBUTANOL
    Publication number: 20230321589
    Abstract: An aqueous CO2 absorbent comprising a combination of 2-amino-2-methyl-1-propanol (AMP) and 3-aminopropanol (AP), or AMP and 4-aminobutanol (AB), is described. A method for capturing CO2 from a CO2 containing gas using the mentioned absorbent, and the use of a combination of AMP and AP, or a combination of AMP and AB are also described.

  • Methods and systems for emissions control in solvent-based CO2 capture processes using CO2
    Patent number: 11413572
    Abstract: A method with corresponding systems for reducing emission of amines to the atmosphere. The method includes a a) introducing a gas containing CO2 into an absorber; b) flowing the flue gas through an absorber having an absorbent with a water-lean solution having less than 50% water and one or more amines, with the absorbent capturing the CO2 and forming a reduced CO2 content gas having a baseline CO2 content; and c) washing the reduced CO2 content gas in a wash column with a wash solution comprising carbonic acid formed by addition of gaseous CO2 into the wash solution. In this method, the washing removes the amines from the reduced CO2 content gas and produces a reduced amine content gas exiting from the wash column.
