Abstract:
A process for the elimination of ammonia in waste waters from a coke oven battery wherein ammonia-containing waste water or ammonia-containing vapor obtained by means of ammonia separation from the waste water are mixed with flue gas from the coke oven battery and sprayed into a NO.sub.x reactor at an elevated temperature with the resulting mixture being subjected to a catalytic redox reaction.
