Abstract: A method for removing NOx from flue gas by SCR includes supplying a reagent for the SCR reaction of NOx into the flue gas, then contacting the flue gas with a catalyst. Supplying the reagent includes supplying a less than stoichiometric amount of reagent, and after contacting the flue gas with a catalyst a final NOx removal step is provided.
