Abstract

L'invention concerne un procédé de réduction de la concentration en oxyde nitrique des gaz résiduaires par irridiation desdits gaz par un rayonnement ultraviolet Les gaz residuaires sont mélangés avec de l'ammoniac avant ladite irraditation pour réduire l'oxygène présent dans lesdits gaz. Procédé simple pouvant être mis en oeuvre de manière intermittente.
