Method for removing carbon dioxide from fluid flows, in particular combustion exhaust gases

摘要

A method for removing carbon dioxide from a fluid flow, wherein a) the fluid flow is brought into contact with an absorption agent, which contains a solution of ammonia and at least one amino carboxylic acid and/or amino sulfonic acid, a charged absorption agent being obtained, and b) the charged absorption agent is regenerated while releasing carbon dioxide. The additional use of the amino carboxylic acid and/or amino sulfonic acid increases the circulation absorption capacity of the absorption agent.
