Patent

CA 2726383

Disclosed herein is a method and system for separating carbon dioxide (CO2) from a C02 containing gas stream containing water vapor and additional impurities, for example, nitrogen, oxygen, sulfur oxides, nitrogen oxides, and mercury. The C02 is captured by subjecting the CO2 gas feed stream to a temperature swing adsorption step. The temperature swing adsorption step comprises an adsorption step for producing a substantially dry carbon dioxide-depleted stream, and an adsorbent regeneration step comprising heating the adsorbent bed to produce a substantially water vapor-free carbon dioxide stream. Moisture from the gas stream containing CO2 is optionally removed by pressure swing adsorption, temperature swing adsorption, membrane separation, or absorption prior to CO2 capture.

L'invention porte sur un procédé et un système pour séparer du dioxyde de carbone (CO2) à partir d'un courant de gaz contenant du CO2 et contenant de la vapeur d'eau et des impuretés additionnelles, par exemple, de l'azote, de l'oxygène, des oxydes de soufre, des oxydes d'azote et du mercure. On capture le CO2 en soumettant le courant d'alimentation de gaz contenant du CO2 à une étape d'adsorption modulée en température. L'étape d'adsorption modulée en température comprend une étape d'adsorption pour produire un courant appauvri en dioxyde de carbone, sensiblement sec, et une étape de régénération d'adsorbant, comprenant un chauffage du lit d'adsorbant pour produire un courant de dioxyde de carbone sensiblement exempt de vapeur d'eau. L'humidité provenant du courant de gaz contenant CO2 est facultativement éliminée par adsorption modulée en pression, adsorption modulée en température, séparation sur membrane ou absorption avant la capture de CO2.
