ABSTRACT:
A description is given of an absorption medium for removing carbon dioxide from a gas stream, which comprises an aqueous solution of at least one amine and at least one aminocarboxylic acid and/or aminosulfonic acid. The concomitant use of an aminocarboxylic acid or aminosulfonic acid reduces the energy required for regeneration of the absorption medium.
