Description

Verfahren zur Umsetzung von Ammankarbonat mit Gips zu Ammansulfat. Nach dem Hauptpatent erfolgt die Umsetzung von Ammankarbonat mit Gips zu Ammensulfat in mit kreisendem Einbau versehenen Reaktionskolonnen, denen von oben die Aufschlämmung von .Gips in Wasser bzw. Sulfatlösung und von unten Ammoniak- und Kohlensäuredämpfe zugeführt werden. Bei diesem Verfahren ist angenommen, daß die Ammoniakdämpfe in Destillierapparaten aus ammoniakhaltigem Wasser abgetrieben sind und die Kohlensäure irgendeiner verfügbaren Quelle entnommen wird. Das ammoniakhaltige Wasser wird durch Auskühlung oder Auswaschung des Ammoniaks aus den Destillationsgasen von Brennstoffen erhalten.Process for converting ammonium carbonate with gypsum to amman sulfate. According to the main patent, ammane carbonate is converted with gypsum to form ammensulfate in reaction columns provided with a circular installation, to which the slurry from above of .gypsum in water or sulphate solution and from below ammonia and carbonic acid vapors are fed. This procedure assumes that the ammonia vapors in Distillers are driven from ammonia-containing water and the carbonic acid taken from any available source. The ammonia-containing water is through Cooling down or washing out of ammonia from the distillation gases of fuels obtain.

Nach der vorliegenden Neuerung sollen nun die entteerten Destillationsgase selbst mit ihrem Gehalt an Ammoniak und Kohlensäure durch den Kolonnenapparat geführt werden. Dieses ist besonders deshalb vorteilhaft, da in den meisten Fällen der Kohlensäuregehalt der Gase vollständig zur Bindung des Ammoniaks als Karbonat ausreicht. Auch das Ammoniak des bei der- Teerscheidung etwa ausfallenden Kondensats läßt sich leicht in das Verfahren wieder einführen, indem .man das Kondensat. mit Kalk abtreibt und das Ammoniak-Wasserdampf-Gemisch vor der Einführung in den Gasstrom und in die Reaktionskolonnen durch eitlen Kühler streichen läßt, um es von Wasser zu befreien. Auch dieses Ammoniak wird genug Kohlensäure in dem Gase finden, um bei der Behandlung mit Gips in schwefelsaures Ammoniak übergeführt zu werden. Die Umsetzung zwischen Ammankarbonat - und Gips erfolgt zweckmäßig bei niedriger Temperatur; eine Erhitzung des Destillationsgases vor dem Kolonnenapparat ist deshalb unnötig, selbst bei kalter Teerscheidung. Ebenso kann ein Dampfzusatz für die Umsetzung in der Reaktionskolonne unterbleiben.According to the present innovation, the tarred distillation gases should now even with their ammonia and carbonic acid content passed through the column apparatus will. This is particularly advantageous because in most cases the carbon dioxide content of the gases is completely sufficient to bind the ammonia as carbonate. That too Ammonia in the condensate which precipitates out during tar separation can easily be removed reintroduce into the process by removing the condensate. drives off with lime and the ammonia-water vapor mixture before introduction into the gas stream and into the reaction columns can be passed through a vain cooler to rid it of water. This ammonia too will find enough carbonic acid in the gases to turn into sulfuric acid when treated with gypsum To be transferred to ammonia. The implementation between Amman carbonate - and plaster of paris takes place expediently at low temperature; a heating of the distillation gas in front of the column apparatus is therefore unnecessary, even with cold tar separation. as well an addition of steam for the reaction in the reaction column can be omitted.
