Process for the continuous production of hydroxylammonium |
摘要 |
Process and equipment for the continuous production of hydroxyl ammonium by reduction of nitrate ions or nitrogen oxides with hydrogen in the presence of a catalyst whereby the hydroxyl ammonium is produced in 2 or more parallel placed hydroxyl ammonium production units which process is optionally part of a process for the production of cyclohexanone oxime in which an inorganic process liquid is cycled from a hydroxyl ammonium synthesis zone (A) to a cyclohexanone oxime synthesis zone (B) and back to the hydroxyl ammonium synthesis zone for example through an extraction zone (C) and a nitric acid production zone (D), in which hydroxyl ammonium synthesis zone hydroxyl ammonium is formed by reduction of nitrate ions or nitrogen oxides with hydrogen in the presence of a catalyst, and in which cyclohexanone oxime synthesis zone hydroxyl ammonium is reacted with cyclohexanone to form cyclohexanone oxime.
