| description | Process for scrubbing out ammonia nitrogen and/or ammonium nitrogen and/or urea nitrogen from exhaust gases enriched with these nitrogen compounds in plants for producing ammonia or urea, wherein the nitrogen compounds first form with a hypochlorite-containing solution in a scrubber an intermediate which under acidic or neutral reaction conditions is reacted to form elemental nitrogen and salt, and the reaction of the nitrogen compounds to form elemental nitrogen and salt proceeds in a pH range of 4 to 6. |
