CO 2 REMOVAL FROM GASES BY MEANS OF AQUEOUS AMINE SOLUTIONS WITH THE ADDITION OF A STERICALLY HINDERED AMINE
First Claim
1. Use of an absorbent for the removal of sour gases from a fluid stream, the absorbent consisting of an aqueous solution with at least two different amines, withany arbitrary amine with a share of more than 50 wt. % in the total amine content of the aqueous solution constituting the first amine component in the aqueous solution, and witha sterically hindered amine with a share of less than 50 wt. % in the total amine content constituting the second amine component in the aqueous solution.the fluid stream being brought into contact with the absorbent at a partial pressure of <
- 200 mbar.

Abstract
A method for removing acid gases from a fluid flow using an absorbent including an aqueous solution with at least two different amines. An 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.
