Abstract:
The present invention relates to a method of cleaning a carbon dioxide rich flue gas stream containing oxygen. The method includes heating the flue gas stream to a temperature suitable for selective catalytic reduction (SCR) of NOX; and reducing at least some of the NOX in the heated flue gas stream to N2 by SCR. Heating of the flue gas stream includes removal of residual oxygen contained in the flue gas by catalytic oxidation of a suitable carburant. The present invention further relates to a gas processing unit.
