Description
Den Gegenstand der vorliegenden Erfindung bildet ein Verfahren zur Gewinnung von Ammonsalzen beim Betriebe von Generatoren. Es ist bekannt, die Ausbeute an Ammoniak durch die Anwesenheit von Wasserdampf zu beeinflussen. In Gemäßheit der vorliegenden Erfindung kann man die Wirkung des im Vergasungsgut bereits vorhandenen Wassers und des während des ProzessesThe subject of the present invention is a method of extraction of ammonium salts when operating generators. It is known the yield of ammonia due to the presence of water vapor to influence. In accordance with the present invention, the effect of what is already present in the gasification material can be used Water and during the process
ίο eingeblasenen Dampfes oder Wassers dadurch erhöhen, daß man dem Vergasungsgut solche Salze zusetzt, welche Wasser binden und es erst bei hoher Temperatur wieder abgeben. Dadurch wird die Ausbeute an Ammoniak günstig beeinflußt. In erster Linie dient der Generatorbetrieb zur Erzeugung von Gas, und die Nebenproduktengewinnung muß sich deshalb im wesentlichen diesem Hauptzweck anpassen. Durch den Zusatz der Hydratwasser bindende Salze wird eine größere Unabhängigkeit der Ammoniakgewinnung von den Bedingungen der Gaserzeugung im allgemeinen erreicht. Insbesondere empfiehlt es sich, die als Abfallprodukte billig erhältlichen Wasser anziehenden Chloride, wie Chlorcalcium, Chlormagnesium u. dgl., zu verwenden. Hierbei ergibt sich der besondere Vorteil, daß praktisch aller Stickstoff der Kohle sich mit dem entsprechend bemessenen Chlorgehalt der Beschickung verbindet, sobald die Bildungstemperatur erreicht ist und in einheitlicher Form als Chlorammonium frei wird; es kann beispielsweise durch fraktionierte Kondensation leicht gewonnen werden, da sich Chlorammonium schon bei 450° in fester Form abscheidet.ίο blown steam or water through it increase that one adds such salts to the gasification, which bind water and it release again at a high temperature. This will reduce the yield of ammonia favorably influenced. The generator operation is primarily used to generate gas and to extract by-products must therefore essentially adapt to this main purpose. By adding the Salts that bind water of hydration make ammonia production more independent achieved by the conditions of gas generation in general. In particular, it is recommended to use the cheap as waste products available water-attracting chlorides such as calcium chloride, magnesium chloride and the like. This has the particular advantage that practically all of the nitrogen in the coal is appropriately sized Chlorine content of the feed connects as soon as the formation temperature is reached and in uniform form when chlorammonium is released; it can for example by fractional Condensation can be easily obtained, since chlorammonium is already at 450 ° in solid form separates.
Man hat bereits vorgeschlagen, den Stickstoffgehalt der aus irgendeiner Feuerung, insbesondere aus Koksöfen herkommenden Verbrennungsgase in Form von Chlorammonium zu gewinnen. Dieser Vorschlag ist unausführbar, weil, der gebundene Stickstoff bei der Verbrennung des Brennstoffes zu freiem Stickstoff mitverbrennt, wenn er nicht sofort in der Feuerzone an Chlor gebunden wird. Ebenso hat man bereits vorgeschlagen, den Luftstickstoff unter Anwendung von Wärme in Form von Chlorammon zu gewinnen.It has already been suggested that the nitrogen content of any furnace, in particular Combustion gases from coke ovens in the form of chlorammonium to win. This suggestion is impracticable because, the bound nitrogen in the Combustion of the fuel to free nitrogen, if it does not burn immediately is bound to chlorine in the fire zone. It has also already been proposed that Obtain atmospheric nitrogen in the form of chlorammon using heat.
Anderseits hat man, ohne an die Bildung von Chlorammon zu denken, zu allen mögliehen Zwecken den Brennstoffen schon Chloride zugesetzt.On the other hand, without thinking about the formation of chlorammon, one has the possibility to get to all of them Chlorides have already been added to the fuels for purposes of this.
Das bei anderen Verfahren übliche Abtreiben mit Kalk gelangt bei dem vorliegenden Verfahren in Wegfall, weil man den Stickstoff der Kohle in einheitlicher Form direkt als Chlorammonium erhält. Man spart also die Aufwendungen für Schwefelsäure zur Bindung des Ammoniaks. Ein weiterer Vorteil besteht darin, daß bei der Gewinnung des Stickstoffs in der einheitlichen Form des Chlorammoniums die Temperatur des Waschwassers bis zur Siedetemperatur gesteigert werden kann, während bei der DarstellungLime wiping, which is common in other methods, is applied to the present one Process in elimination, because the nitrogen of the coal is obtained in a uniform form directly as chlorammonium. You save So the expenses for sulfuric acid to bind the ammonia. Another advantage consists in the fact that in the production of nitrogen in the uniform form of the Chlorammonium increases the temperature of the wash water up to the boiling point can be while in the display
