Patent

CA 2528205

A process for recovering CO2 from a feed gas stream comprises treating the feed gas stream with a regenerated absorbent comprising at least one tertiary amine absorbent having a pKa for the amino function of from about 6.5 to about 9 in the presence of an oxidation inhibitor to obtain a CO2 rich stream and subsequently treating the CO2 rich stream to obtain the regenerated absorbent and a CO2 rich product stream. The feed gas stream may also include SO2 and/or NOx.

L'invention concerne un procédé de récupération de CO¿2? dans un flux gazeux d'entrée. Ce procédé consiste : à traiter ledit flux gazeux au moyen d'un absorbant régénéré contenant au moins un absorbent amine tertiaire dont le pK¿a? pour la fonction amino est compris entre environ 6,5 et environ 9, en présence d'un inhibiteur d'oxydation, de sorte à obtenir un flux riche en CO¿2? ; puis à traiter ledit flux riche en CO¿2? afin d'obtenir l'absorbant régénéré et un flux de produit riche en CO¿2?. Le flux gazeux d'entrée peut également contenir du SO¿2? et/ou du NO¿x?.
