More Information
Summary:NO 2 may be removed from a carbon dioxide feed gas comprising NO x and at least one "non-condensable" gas as contaminants by passing the feed gas at a first elevated pressure through a first adsorption system that selectively adsorbs at least NO 2 to produce at least substantially N0 2 -free carbon dioxide gas. The adsorption system is at least partially regenerated using a carbon dioxide-rich gas recovered from the substantially NO 2 -free carbon dioxide gas after purification. The invention has particular application in removing NO x and water from flue gas generated by oxyfuel combustion.
