Carbon dioxide-containing feed stream such as flue gas is treated to produce a high-purity carbon dioxide stream by a series of steps including removing SOx and NOx with activated carbon, carrying out subambient- temperature processing to produce a product stream and a vent stream, and treating the vent stream by pressure swing adsorption or by physical or chemical absorption to produce a product stream which is recycled to the feed stream.
Un flux d'alimentation contenant du dioxyde de carbone tel que du gaz de carneau est traité pour produire un flux de dioxyde de carbone à haute pureté à l'aide d'une série d'étapes consistant à éliminer le SOx et le NOx avec du charbon actif, à mettre en oeuvre un traitement à température sub-ambiante pour produire un flux de produit et un flux d'évent, et à traiter le flux d'évent par adsorption modulée en pression ou par absorption physique ou chimique afin de produire un flux de produit qui est recyclé vers le flux d'alimentation.
