Abstract
The invention pertains to a system for purification of a carbon dioxide rich flue gas generated in a boiler combusting a fuel in the presence of a gas containing oxygen, and being contaminated by NOx gases, wherein the system comprising one or more gas drier(s) comprising desiccants for removal of at least a portion of water content of the further compressed carbon dioxide rich flue gas; and a closed loop connected to the drier(s) for regeneration of desiccants of the drier(s) wherein the NOx gases are removed substantially separately from the water vapor. The invention pertains also to a method for removing the NOx gases substantially separately from the water vapor.
