Abstract
La présente invention concerne un procédé d'élimination du dioxyde de carbone présent dans un gaz de procédé, ledit procédé d'élimination comprenant les étapes consistant a) à introduire une solution ammoniacale dans un dispositif d'absorption, ledit dispositif d'absorption comprenant au moins un premier absorbeur ; b) à mettre en contact ladite solution ammoniacale avec le gaz de procédé dans ledit premier absorbeur, ladite solution ammoniacale capturant au moins une partie du dioxyde de carbone présent dans le gaz de procédé ; c) à évacuer la solution ammoniacale du dispositif d'absorption ; d) à faire refroidir la solution ammoniacale, cela entraînant la précipitation d'au moins une partie du dioxyde de carbone capturé sous la forme d'un sel solide ; e) à introduire la solution ammoniacale refroidie dans un séparateur dans lequel au moins une partie des particules solides précipitées sont éliminées de la solution ammoniacale, après quoi la solution ammoniacale est évacuée du séparateur ; f) à faire chauffer la solution ammoniacale ; et g) à réintroduire la solution ammoniacale ainsi chauffée dans le dispositif d'absorption. L'invention concerne également un système d'élimination du dioxyde de carbone.
