Description
Verfahren zur Herstellung von Ammoniumsulfxt. Bekanntlich muss man das synthetisch gewonnene Ammoniak, wenn es für Dünger Verwendung finden soll, an eine Säure bin den, und zwar benutzt man im allgemeinen dazu Schwefelsäure. Die Bindung des Am moniaks würde einfacher werden und durch Vermeidung der Kosten für den Betrieb von Schwefelsäurekammern und Schwefelsäure türmen auch weit billiger, wenn man in be kannter Weise das Ammonium an schweflige Säure binden und das Ammoniumsulfit durch Oxydation in Sulfat verwandeln könnte.
Der Grund, weshalb ein solches Verfahren im Grossbetrieb noch nicht zur Durchführung gekommen ist, liegt an der Umständlichkeit, mit der die Oxydation des Sulfites verbunden ist, die besonders dann in Erscheinung tritt, wenn man die Oxydation bis zur fast voll stündigen Umwandlung in Sulfat treiben will.
Wir haben nun gefunden, dass diese Oxy dation sowohl von lufttrockenem, wie auch von angefeuchtetem und schliesslich auch von in Lösung befindlichem Ammoniumsulfit um ein Mehrfaches schneller geht, die dazu nötigen Anlagen also auch um ein Mehr faches kleiner sein können, wenn man die Oxydation mit konzentriertem Sauerstoff, zum Beispiel mit durch Elektrolyse gewon nenem oder mit Sauerstoff aus Luftverflüs- sigungsanlagen, durchführt.
Besondere Vorteile bietet das Verfahren, wo Wasserkräfte zur Verfügung stehen und wo man infolgedessen die Herstellung des für die Ammoniaksynthese nötigen Wasser stoffes und des für die Oxydation nötigen Sauerstoffes elektrolytisch vornimmt. Für den bei der Elektrolyse anfallenden Sauer stoff hat man bis heute wegen seiner grossen Mengen keinen Verwendungszweck gefunden.
In vorliegendem kombiniertem Verfahren da gegen ermöglicht er die Vermeidung der An lagen zur Umwandlung von S02 in Schwefel säure und verbilligt die Anlagen für den Oxydationsvorgang des Sulfites. Man kann demnach aus synthetischem Ammoniak und schwefliger Säure Ammoniumsulfit her stellen und den bei der elektrolytischen Ge- winnung des für die Ammoniaksynthese nö tigen Wasserstoffes entstehenden Sauerstoff zur Oxydation des Sulfites verwenden.
Process for the production of Ammoniumsulfxt. It is well known that the synthetically obtained ammonia, if it is to be used for fertilizer, has to be bound to an acid, namely sulfuric acid is generally used for this. The binding of the ammonia would be easier and, by avoiding the costs of operating sulfuric acid chambers, and sulfuric acid piling up, it would also be much cheaper if the ammonium could be bound to sulphurous acid in a known manner and the ammonium sulphite could be converted into sulphate by oxidation.
The reason why such a process has not yet been carried out in large-scale operations is due to the inconvenience associated with the oxidation of the sulphite, which is particularly evident when the oxidation is carried out until it is almost completely converted into sulphate want.
We have now found that this oxidation of both air-dry and humidified ammonium sulphite, and finally also of ammonium sulphite in solution, is several times faster, so the necessary systems can also be several times smaller if the oxidation is also carried out concentrated oxygen, for example with oxygen obtained by electrolysis or with oxygen from air liquefaction systems.
The process offers particular advantages where water forces are available and where, as a result, the production of the hydrogen required for ammonia synthesis and the oxygen required for oxidation is carried out electrolytically. The oxygen produced in electrolysis has not yet been used because of its large quantities.
In the present combined process, on the other hand, it enables the avoidance of the systems for converting S02 into sulfuric acid and makes the systems for the oxidation process of the sulfite cheaper. Accordingly, ammonium sulphite can be produced from synthetic ammonia and sulphurous acid and the oxygen produced during the electrolytic production of the hydrogen required for ammonia synthesis can be used to oxidise the sulphite.
