Patent ID: 7485275

Claim:
A method for removing acid gases and ammonia from a fluid stream comprising: an absorption step wherein the fluid stream comprising the acid gases and ammonia is brought into contact with an aqueous absorption medium, and the absorption step further comprises obtaining a fluid stream which is depleted of acid gases and ammonia, and also an absorption medium stream which is charged with acid gases and ammonia and a desorption step, wherein the acid gases and the ammonia are stripped out of the absorption medium and the condensable fractions thereof are condensed, and the desorption step further comprises obtaining a condensate and also a purified absorption medium stream, wherein the method further comprises ejecting in part or completely the condensate from the desorption step, or feeding it in part or completely to a distillation column in which ammonia is separated off overhead as aqueous solution or in the pure state and an aqueous bottom stream is obtained which is recycled to the absorption step or the desorption step.
