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.
Claims8
An aqueous CO2 absorbent comprising a combination of 2-amino-2-methyl-1-propanol (AMP) and 3-aminopropanol (AP).
A method for capturing CO2 from an CO2 containing gas, where the CO2 containing gas is brought in countercurrent flow to a CO2 absorbent in an absorber to give a CO2 depleted gas that is released into the surroundings, and a CO2 rich absorbent that is collected in the bottom of the absorber, regenerated and recycled into the absorber, wherein the CO2 absorbent is an aqueous CO2 absorbent comprising a combination of 2-amino-2-methyl-1-propanol (AMP) and 3-aminopropanol (AP).
A method of using an aqueous solution of a combination of AMP and AP as an absorbent for CO2 in a method for capturing CO2 from a CO2 containing gas, said method comprising contacting the CO2 containing gas with the aqueous solution.
