Abstract
A premix is described for producing an absorption medium for removing acid gases from fluid streams. The premix comprises at least one alkanolamine, piperazine and water, the premix having a total amine content of more than 65% by weight, the molar ratio of water to piperazine in the premix being 1.6 to 4.8. The premix is characterized by a low solidification point. It is diluted with water and/or alkanolamine to give the ready-to-use absorption medium.
