ABSTRACT:
In a process for the removal of sulfur dioxide and nitrogen oxides, the waste gas is cooled and scrubbed with a physical absorbent selective for sulfur dioxide. The nitrogen oxides are catalytically removed from the waste gas by reaction with ammonia, which is added to the waste gas prior to the scrubbing step. The catalyst packing is disposed in the same housing and is at the hot end of a regenerator for cooling the waste gas and is arranged upstream of the regenerator packing. The cooling is conducted to the dew point so as to dissolve residual ammonia, and air is used to remove the ammonia during regeneration, the resultant heated air being primarily used in the combustion zone.
