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.

Aqueous CO2 absorbent comprising 2-amino-2-methyl-1-propanol and 3-aminopropanol

A method with corresponding systems for reducing emission of amines to the atmosphere. The method includes a a) introducing a gas containing COinto 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 COand forming a reduced COcontent gas having a baseline COcontent; and c) washing the reduced COcontent gas in a wash column with a wash solution comprising carbonic acid formed by addition of gaseous COinto the wash solution. In this method, the washing removes the amines from the reduced COcontent gas and produces a reduced amine content gas exiting from the wash column.
