   Das Verfahren lässt sich auch vorteilhaft mit solchen Gasen ausführen, die man aus Gaswasser, Jauche,   r, efaultem   Harn,   KondenswÅasse1'11   der Torf-, Schlick-, Braunkohlen-, Schiefer-usw. Destillationen, Kondensaten der Sauggasapparate usw. abtreiben kann. Diese Gase liessen sich aus, den oben angeführten Gründen bisher nicht unmittelbar zu reinem Ammoniumnitrat verarbeiten.

   For operational reasons it is sometimes advantageous to remove ammonia from the raw gases

 had settled.



   The process can also be carried out advantageously with gases that are obtained from gas water, liquid manure, r, rotten urine, condensate water, peat, silt, lignite, slate, etc. Can drive off distillations, condensates of the suction gas apparatus, etc. For the reasons given above, these gases could not be processed directly into pure ammonium nitrate so far.

Claims (1)

PATENT-ANSPRUCH : Verfahren zur Herstellung von reinem Ammoniumnitrat aus entleerten Gasen der trockenen Destillation oder den aus Gaswasser und ähnlichen unreinen Ammoniaklösungen abgetriebenen Gasen durch Absorption mit Kalziumnitratlösung, dadurch gekennzeichnet, dass man die Gase unentwässert und unabgekühlt in Kalziumnitratlösung leitet, von dem ausgeschiedenen Kalziumkarbonat trennt und die Lösung, gegebenenfalls nach vorherigem Ansäuern mit Salpetersäure und Erhitzen, weiter verarbeitet. PATENT CLAIM: Process for the production of pure ammonium nitrate from emptied gases of dry distillation or the gases driven off from gas water and similar impure ammonia solutions by absorption with calcium nitrate solution, characterized in that the gases are passed undewatered and uncooled in calcium nitrate solution, from the calcium carbonate which has separated out, and the solution is separated, if necessary, after previous acidification with nitric acid and heating, further processed.
