Abstract

A method for reducing detrimental nitrogen compounds of a pulp mill. In the method, the ammonia contained in weak odor gases is combusted into nitrogen oxide by supplying the weak odor gases to the combustion zone for strong odor gases in the odor gas combustor, whereby the nitrogen oxide formed reacts under reducing conditions with ammonia separated from black liquor, forming molecular nitrogen and water.
