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.
Claims16
An aqueous CO2 absorbent comprising:
- 2-amino-2-methyl-1-propanol (AMP);
- and
- one of:
- 3-aminopropanol (AP);
- and
- 4 aminobutanol (AB).
A method for capturing CO2 from a 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), or AMP and 4-aminobutanol (AB).
