Abstract
L'invention concerne un procédé de récupération d'acide nitrique à partir d'acide nitrique ou d'un nitrate usé, ainsi qu'un appareil pour la mise en oeuvre de ce procédé. Le procédé selon l'invention consiste à incorporer ou absorber de l'acide nitrique usé et/ou un nitrate usé dans un véhicule inorganique susceptible d'absorber l'huile et formé de granules véhicules de nitrate contenant de l'eau sous forme d'un hydroxyde, d'un hydrate ou d'humidité d'absorption en quantité suffisante pour engendrer une vapeur d'acide nitrique de façon stable, lesdits granules étant pratiquement non collants à la température de décomposition du nitrate, à chauffer les granules formés tout en maintenant l'état pratiquement non collant des granules pour décomposer le nitrate contenu dans les granules en une vapeur d'acide nitrique, et à récupérer la vapeur d'acide nitrique engendrée.
