Trotz der bedeutenden Ausdehnung, welche die Ammoniak-Soda-Fabrikation in den letzten Jahren genommen, wird dieselbe bei dem heutigen Stande dieser Fabrikationsmethode doch nicht im Stande sein, den Leblanc-Soda-Procefs überall mit Erfolg zu verdrängen, da die Nebenproducte des Leblanc-Processes je nach der Oertlichkeit der Fabrikationsanlage bald geringere, bald bedeutendere Werthe repräsentiren. Andererseits mufs wieder anerkannt werden, dafs der Ammoniak-Soda-Procefs eine so reine Soda liefert, wie sie durch den Leblanc-Procefs nur schwierig zu erhalten ist, weshalb dieselbe von einzelnen Consumenten der Leblanc-Soda vorgezogen wird. Es können also beide Fabrikationsmethoden neben einander bestehen, und darum bemühten sich die Erfinder, ein Verfahren aufzusuchen, durch welches beide Fabrikationsmethoden mit einander combinirt werden können, so dafs also ein Theil der Sodaproduction nach dem Leblanc'sehen Verfahren, ein anderer Theil nach dem Ammoniakverfahren dargestellt wird, und zwar unter gleichzeitiger Regenerirung von Schwefel und Ammoniak aus den bei diesen beiden Fabrikationsmethoden entstehenden Nebenproducten.In spite of the significant expansion that the ammonia-soda production took in the last Years ago, it is still used at the current level of this manufacturing method not be able to displace the Leblanc-Soda-Procefs with success everywhere, since the by-products of the Leblanc process, depending on the location of the manufacturing plant, soon lower, soon to represent more important values. On the other hand, it must be recognized again that the ammonia-soda process produces as pure a soda as it does through the Leblanc process is difficult to obtain, which is why it is used by individual consumers of Leblanc soda is preferred. So both manufacturing methods can coexist, and so the inventors endeavored to find a method by which both Manufacturing methods can be combined with one another, so that a part of the Soda production according to the Leblanc process, another part is prepared by the ammonia process, with simultaneous regeneration of sulfur and Ammonia from the by-products resulting from these two manufacturing methods.
Das Verfahren ist folgendes:The procedure is as follows:
Die Sodarückstände der Leblanc-Soda-Fabrikation werden in der Wärme mit Chlormagnesium behandelt, genau so wie dies in dem Verfahren für die Regeneration des Sodarückstandes mittelst Chlormagnesium angegeben wurde, D. R. P. No. 4610.The soda residues from Leblanc soda production are treated in the heat with magnesium chloride, just like in the process for the regeneration of the soda residue was given by means of chloromagnesium, D. R. P. No. 4610.
Durch die Einwirkung von Chlormagnesium auf Schwefelcalcium entsteht einerseits Schwefelwasserstoff, welcher weiter auf Schwefel oder Schwefelsäure verarbeitet wird (wie dies in dem oben angeführten Patent näher beschrieben), andererseits bildet sich Magnesia und Chlorcalcium. Da aber zur vollständigen Zersetzung des Schwefelcalciums ein kleiner Ueberschufs von Chlormagnesium angewendet werden mufs, so wird nun so viel gebrannter Kalk oder Dolomit zugesetzt, um sämmtliche Magnesia zu fällen. Der Niederschlag wird filtrirt und gewaschen und das erhaltene magnesiahaltige Product im feuchten oder getrockneten Zustande mit entsprechenden Mengen von chlorammonmmhaltigen Laugen von der Ammoniak-Soda-Fabrikation in geeigneten Gefäfsen vermischt und erhitzt. Hierbei setzt sich die Magnesia mit dem Chlorammonium um in Ammoniak, welches wieder zur Ammoniak-Soda-Fabrikation dient, und in Chlormagnesium, welches zur Zersetzung neuer Mengen von Rückständen der Leblanc-Soda-Fabrikation verwendet wird.On the one hand, the action of magnesium chloride on calcium sulphide produces hydrogen sulphide, which is further processed on sulfur or sulfuric acid (as in the patent cited above), on the other hand magnesia and calcium chloride are formed. But there is a small excess for the complete decomposition of the calcium sulfur of magnesium chlorine must be used, so much quick lime or dolomite will be used added to precipitate all of the magnesia. The precipitate is filtered and washed and the resulting magnesia-containing product in the moist or dried state with corresponding Quantities of alkaline solutions containing chlorine ammonia from the ammonia-soda factory are mixed in suitable vessels and heated. Here, the magnesia and the chlorammonium are converted into ammonia, which again for the production of ammonia and soda, and in chlorine magnesium, which is used to decompose new Quantities of residues from Leblanc soda production are used.
