CO2 REMOVAL FROM GASES BY MEANS OF AQUEOUS AMINE SOLUTIONS WITH THE ADDITION OF A STERICALLY HINDERED AMINE

摘要

The invention relates to the use of an absorbent for removing acid gases from a fluid flow, comprising an aqueous solution with at least two different amines. Any amine in a proportion of greater than 50 wt.% of the total amine amount in the aqueous solution is the first amine component in the aqueous solution, and a sterically hindered amine in a proportion of less than 50 wt.% is the second amine component in the aqueous solution. The fluid flow is brought into contact with the absorbent at a partial pressure of < 200 mbar.
