Patent EP-0001787-A1 (EP)
Inventor: KOFF FRED W
IPC: B01J39/04
Filed: 1978-10-19
Abstract: A process for separating hydroxylamine from an aqueous solution containing hydroxylammonium salts in mixture with salts of predominantly monovalent cations whose corresponding free bases have base , dissociation constants greater than 10 -7 . Said solution is passed through a bed of cation exchange resin loaded predominantly with monovalent cations hereby hydroxylammonium and the other cations in solution substantially displace said cations from the resin. A second aqueous solution containing a monovalent amine or hydroxide base of at least 0.5 molar concentration having a dissociation constant greater than 10 -7  is passed through the resin bed whereby hydroxylamine is preferentially released to the solution and the resin is correspondingly loaded with the cation of said base. Hydroxylammonium salts can be crystallized from the solution after addition of a stoichiometric amount of an appropriate acid.

Abstract: Beim Aufschluss von Rohphosphaten mit Schwefelsäure fällt verdünnte Phosphorsäure an, die für eine Düngemittel-herstellung aufkonzentriert werden muss. Die Aufkonzentrierung erfolgt in mehreren hintereinandergeschalteten Vakuum-Verdampferstufen (2, resp. 13) mit separater Kreislaufführung (3,4,5,7,9) und (3,4,6,8,9) resp. (14,15,16,17,18) der Phosphorsäuren. Die Phosphorsäuren (1) resp. (12) werden ausserhalb der Verdampfer indirekt aufgeheizt. Diese Aufheizung soll in Verbindung mit einer Schwefelsäureanlage möglichst einfach und unter weitgehender Vermeidung des Einsatzes von wertvoller Energie erfolgen. Dies geschieht dadurch, dass die Aufheizung mittels der Wärme erfolgt, die in den Schwefelsäuren (27) und (32) der SO3-Absorptionssysteme der Schwefelsäurekontaktanlage anfallt und aus diesen abgeführt werden muss.
