Abstract

Procédé de dépollution des eaux résiduaires d'une fabrication de nitrate d'ammonium, permettant de récupérer l'ammoniac et le nitrate d'ammonium contenus dans les effluents liquides de cette fabrication en les concentrant dans un évaporateur et en recyclant l'azote ainsi récupéré au réacteur pour former une solution concentrée de nitrate d'ammoniac, caractérisé par le fait que la récupération est effectuée dans un évaporateur à multiple effet chauffé par la vapeur, exédentaire, par rapport aux besoins de la fabrication, et produite par la réaction de l'ammoniac sur la solution d'acide nitrique dans le réacteur.
