CA 2742533

A method for removal of CO2 from a flue gas stream, comprising the steps of : a) contacting (101) a flue gas stream comprising CO2 (102) with a first absorption liquid comprising NH3 (103) such that the flue gas stream is depleted in CO2; b) contacting (106) the flue gas stream depleted in CO2 (105) of step a) with a second absorption liquid (107) such that NH3 from the flue gas stream is absorbed in said second absorption liquid to form a flue gas stream depleted in CO2 and NH3 (109); c) separating (110) NH3 from the second absorption liquid such that a gas stream comprising NH3 (114) is obtained; d) contacting (113) said gas stream comprising NH3 separated in step c) with a third absorption liquid (115) such that NH3 is absorbed in said third absorption liquid. A system for removal of CO2 from a flue gas stream, the system comprising: a CO2 absorption stage; an NH3 absorption stage; and a reabsorption stage.

L'invention concerne un procédé d'élimination du CO2 d'un courant de gaz de combustion, comprenant les étapes consistant à : a) mettre un courant de gaz de combustion comprenant du CO2 (102) en contact (102) avec un premier liquide d'absorption comprenant du NH3 (103) afin que le courant de gaz de combustion soit appauvri en CO2; b) mettre le courant de gaz de combustion appauvri en CO2 (105) de l'étape a) en contact (106) avec un deuxième liquide d'absorption (107) afin que le NH3 du courant de gaz de combustion soit absorbé dans ledit deuxième liquide d'absorption pour former un courant de gaz de combustion appauvri en CO2 et en NH3 (109); c) séparer (110) le NH3 du deuxième liquide d'absorption afin d'obtenir un courant gazeux comprenant du NH3 (114); d) mettre ledit courant gazeux comprenant du NH3 séparé dans l'étape c) en contact (113) avec un troisième liquide d'absorption (115) afin que le NH3 soit absorbé dans ledit troisième liquide d'absorption. L'invention concerne également un système d'élimination du C02 contenu dans un courant de gaz de combustion, le système comprenant un étage d'absorption de C02, un étage d'absorption de NH3, et un étage de réabsorption.
