Abstract:
The invention relates to a new method for removing and recovering of acid gases from a gaseous mixture in an absorption plant by adding an organic acid to a stream of the rich absorbent in the desorber in order to release acid gas by shifting the acid gas equilibrium towards the gas side, and the organic acid is subsequently separated from the absorbent. With this method, the energy consumption of the process is substantially reduced. The invention also relates to an apparatus for performing this method.
