| titleOfInvention | Preparation and treatment of hydroxyl ammonium salt solution |
| abstract | The present invention relates to a method for preparing and treating a hydroxylammonium salt solution, wherein an aqueous acidic reaction medium is circulated between a hydroxylammonium salt synthesis zone and an oxime synthesis zone, and is converted to nitrate or nitrate. Is supplied as a nitrogen source for the formation of hydroxylammonium salts to the liquid maintained in circulation, so that the nitrate ions are catalytically reduced to hydrogen, and the ammonium ions produced as a by-product of the reduction of nitrate ions are produced during the catalytic combustion of ammonia. It is removed in contact with a circulating fluid of a stream of nitrogen oxides, wherein 0.01 to 5% by weight of the nitrogen oxides produced during combustion are used to reduce ammonium ions to nitrogen and the rest of the nitrogen oxides are used for the production of nitric acid. do. |
