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.
L'invention concerne un nouveau procédé d'élimination et de capture de gaz acides à partir d'un mélange gazeux dans une unité d'absorption en ajoutant un acide organique au flux riche en absorbant dans le désorbeur, de manière à relâcher des gaz acides en déplaçant l'équilibre des gaz acides du côté du gaz, l'acide organique étant par la suite séparé de l'absorbant. En utilisant ce procédé, la consommation d'énergie est réduite de manière substantielle. L'invention concerne également un appareil utilisé pour mettre en oeuvre ce procédé.
