Patentiert im Deutschen Reiche vom 10. Dezember 1913 ab.Patented in the German Empire on December 10, 1913.
Die Gewinnung des gebundenen Ammoniaks aus ammoniakhaltigen Flüssigkeiten, insbesondere aus den bei der trockenen Destillation der Steinkohle und anderer Brennstoffe entstehenden Gaswässern sowie den Waschwässern der Generator- und Gichtgase geschieht bisher in der Weise, daß das Gaswasser, eventuell nach geeigneter Vorwärmung, mit Kalkmilch behandelt und das in FreiheitThe recovery of bound ammonia from liquids containing ammonia, in particular from the dry distillation of coal and other fuels Gas water as well as the washing water of the generator and furnace gases happens so far in such a way that the gas water, possibly after suitable preheating, treated with milk of lime and that in freedom
ίο gesetzte Ammoniak mittels Dampf abdestilliert wird. Das Verfahren hat aber den Nachteil, daß die Klärung des abgetriebenen Wassers und die Fortschaffung des sich absetzenden Kalkschlammes umständlich und schwierig ist.ίο set ammonia is distilled off by means of steam will. However, the process has the disadvantage that the clarification of the expelled water and the removal of the settling water Lime sludge is cumbersome and difficult.
Die vorliegende Erfindung vermeidet diese Mängel dadurch, daß die Austreibung des gebundenen Ammoniaks nicht mehr wie bisher durch Kalk oder andere Alkalien erfolgt, sondem ^ daß die Zersetzung des im Gaswasser enthaltenen gebundenen Ammoniaks durch die mineralischen Bestandteile fester Brennstoffe, wie Holz, Torf, Braunkohle, Steinkohle, An-The present invention avoids these shortcomings by allowing the expulsion of the bound Ammonia no longer takes place as before through lime or other alkalis, but rather that the decomposition of the in the gas water bound ammonia contained by the mineral components of solid fuels, such as wood, peat, lignite, hard coal,
'■ thrazit usw., erfolgt, welche zweckmäßig in Form von Asche, Schlacke usw. oder auch in •Form von" Koksgrus zur Anwendung gelangen. '■ thrazit, etc., takes place, which is expedient in In the form of ash, slag, etc. or in the form of "coke breeze".
Da die Schlacke bzw. Asche von Torf, Braunkohle und Steinkohle entweder gar keine oder nur geringe Mengen von Kalium- bzw. Natriumkarbonat enthält, so ist die Zersetzung der Ammoniaksalze in der Hauptsache auf die Wirkung der an Kieselsäure oder Tonerde gebundenen Basen, wie Eisenoxyd, Magnesia und Kalk, zurückzuführen. Dies beweist auch der Umstand, daß der wässerige Auszug der Schlacke nur etwaSince the slag or ashes of peat, brown coal and hard coal either none at all or contains only small amounts of potassium or sodium carbonate, the decomposition occurs the ammonia salts mainly on the action of the silica or alumina bound bases such as iron oxide, magnesia and lime. This also proves the fact that the aqueous extract of the slag is only about

denes Ammoniak frei macht als die Schlacke selbst.releases more ammonia than the slag itself.
Das Verfahren kann in der Weise ausgeführt werden, daß das rohe oder zuvor von flüchtigem Ammoniak befreite Wasser in Berührung mit Schlacke, Asche usw. gebracht wird und das in Freiheit gesetzte Ammoniak in bekannter Weise durch Dampf, Luft usw. ausgetrieben und gewonnen wird. Es hat sich nämlich gezeigt, daß die Schlacken- undAschenbestandteile der Kohle imstande sind, die Gesamtmenge des gebundenen Ammoniaks aus dem durch diese Stoffe geleiteten Ammoniakwasser in Freiheit zu setzen und gewinnbar zu machen. Die Schlacke selbst erleidet dabei keine äußerlich erkennbare Veränderung und kann gegebenenfalls ihrer bisher üblichen Verwendung zugeführt werden, während das ablaufende ammoniakfreie Wasser vollkommen klar ist.The process can be carried out in such a way that the raw water or water previously freed from volatile ammonia is brought into contact with slag, ash, etc., and the ammonia liberated is expelled and recovered in a known manner by steam, air, etc. It has been shown that the slag and ash constituents of coal are capable of releasing the total amount of bound ammonia from the ammonia water passed through these substances and making it recoverable. The slag itself does not undergo any externally noticeable change and can, if necessary, be used for its hitherto customary use, while the ammonia-free water that runs off is completely clear.
Zur Ausführung des Verfahrens kann man so verfahren, daß man die Schlacke in einen Destillierapparat bekannter Art bringt, so daß das Abwasser in dem einen Teile der Kolonne seines flüchtigen Ammoniaks und im anderen Teile durch Behandlung mit Schlacke seines gebundenen Ammoniaks beraubt wird.To carry out the process, one can proceed in such a way that the slag is in a Distillation apparatus of known type brings so that the waste water in one part of the column of its volatile ammonia and in the other part by treatment with slag of its bound ammonia is deprived.
Man kann aber auch die Abtreibung des flüchtigen und des gebundenen AmmoniaksBut you can also abort volatile and bound ammonia
nacheinander so vornehmen, daß das von der Destillierkolonne kommende, von flüchtigem Ammoniak freie Wasser einem mit Schlacke usw. beschickten geschlossenen Gefäß zugeführt wird, wo es sein gebundenes Ammoniak verliert, worauf das in Freiheit gesetzte Ammoniak entweder durch die vorerwähnte Destillierkolonne mit dem flüchtigen Ammoniak gemeinsam entweicht, oder dem ausgetriebenenone after the other so that the coming from the distillation column is of volatile Ammonia-free water is supplied to a closed vessel filled with slag, etc. where it loses its bound ammonia, whereupon the ammonia set free either through the aforementioned distillation column together with the volatile ammonia escapes, or the expelled

Man kann aber auch das flüchtige und das gebundene Ammoniak getrennt gewinnen und weiter verarbeiten.ίο volatile ammonia behind the aforementioned The distillation column is fed to a suitable point and is obtained with this. Man but can also extract the volatile and the bound ammonia separately and process them further.
Zur Erzielung eines kontinuierlichen Betriebes ist es vorteilhaft, mehrere Schlackengefäße, wie vorgeschrieben, zu verwenden und nach- oder nebeneinander einzuschalten, wenn eines derselben zwecks Neubeschickung mit Schlacke aus dem Fabrikationsgange ausgeschaltet wird. Das Schlackenfilter kann dabeiTo achieve continuous operation, it is advantageous to have several slag vessels, To be used as prescribed and to be switched on one after the other or next to one another if one of these switched off for the purpose of refilling with slag from the manufacturing process will. The slag filter can thereby
' - vorteilhaft mit einer oberen und einer unteren Öffnung zur leichteren Beschickung mit neuer Schlacke bzw. zur schnelleren Entfernung der ausgebrauchten Schlacke versehen sein.'- advantageously with an upper and a lower Opening for easier loading with new slag or for faster removal of the spent slag be provided.
Das vorbeschriebene Verfahren vermeidet die umständliche Bereitung von Kalkmilch und deren Zuführung durch Pumpen in die Kolonne sowie die Wiederabscheidung des Kalkes aus dem Abwasser und verwendet vorteilhaft im eigenen oder in anderen Betrieben erzeugte, sonst wertlose Abfallprodukte, wie Schlacke, Asche, Koksgrus usw.The method described above avoids the laborious preparation of milk of lime and their feeding by pumps into the column as well as the re-separation of the lime from the wastewater and used advantageously Otherwise worthless waste products produced in-house or in other companies, such as Slag, ash, coke breeze, etc.
An Stelle der vorbeschriebenen mineralisehen Bestandteile fester Brennstoffe, wie Schlacke, Asche usw., kann auch ein wässeriger Auszug aus diesen Stoffen in geeigneter Weise zur Austreibung des gebundenen Ammoniaks Verwendung finden.Instead of the above-described mineral components of solid fuels, such as Slag, ash, etc., can also be an aqueous extract from these substances in a suitable manner Way to drive out the bound ammonia use.
