The present application relates to systems and processes for removal of gaseous contaminants from gas streams. In particular, the application relates to a process for removal of gaseous contaminants from a gas stream comprising contacting the gas stream with a wash solution to remove gaseous contaminants from the gas stream by absorption into the wash solution; and regenerating the used wash solution to remove gaseous contaminants from the used wash solution, to provide a regenerated wash solution and a gas comprising removed contaminants, wherein in a first regeneration stage the gas comprising removed contaminants is cooled to minimize loss of water vapor from the regeneration step.

La présente invention a pour objet des systèmes et des procédés pour l'élimination de contaminants gazeux de courants gazeux. En particulier, l'invention concerne un procédé pour l'élimination de contaminants gazeux d'un courant gazeux comprenant la mise en contact du courant gazeux avec une solution de lavage pour éliminer les contaminants gazeux du courant gazeux par absorption dans la solution de lavage ; et la régénération de la solution de lavage usée pour éliminer les contaminants gazeux de la solution de lavage usée, pour fournir une solution de lavage régénérée et un gaz comprenant les contaminants éliminés. Dans une première étape de régénération, le gaz comprenant les contaminants éliminés est refroidi pour minimiser la perte de vapeur d'eau provenant de l'étape de régénération.
