von schwefelsaurem Ammoniak.from sulfuric acid ammonia.

In den meisten Gasanstalten wird das Leuchtgas von den darin enthaltenen Ammoniakverbindungen nur unvollständig befreit, weil man zu seiner Reinigung aufser der Waschung bisher fast ausnahmslos Kalk und Eisenoxyd anwendete. Ein Versuch, Schwefelsäure zum Reinigen des Gases anzuwenden, welche man in Form von damit getränktem Sägemehl in die Fabrikation einführte, ist wieder aufgegeben worden, weil das in dem Sägemehl gebildete schwefelsaure Ammoniak zu reich war an humosen und theerigen Substanzen, sowie an Rhodanverbindungen. Auch die Anwendung des Superphosphates zur Aufnahme des Ammoniaks aus dem Leuchtgase, wie sie in jüngster Zeit vorgeschlagen ist, leidet an dem Uebelstande, dafs hierdurch der werthvolle wasserlösliche phosphorsaure Kalk in geringwertigen unlöslichen präcipitirten phosphorsauren Kalk verwandelt wird, sowie daran, dafs das von dem Superphosphat aufgenommene Rhodanammonium daraus ohne weitere Wertriverminderung des Phosphates nicht entfernt werden kann.In most gas stations, the luminous gas is made up of the ammonia compounds it contains only incompletely liberated, because one has hitherto been cleansed besides washing almost without exception used lime and iron oxide. An attempt to use sulfuric acid for cleaning of the gas, which is used in the manufacture in the form of sawdust soaked in it introduced has been abandoned because the sulfuric acid formed in the sawdust Ammonia was too rich in humic and tarry substances and rhodan compounds. Also the use of the superphosphate to absorb the ammonia from the Luminous gases, as it has recently been proposed, suffers from the disadvantage that this results in them valuable water-soluble phosphoric acid lime in insoluble, insoluble, precipitated phosphoric acid Lime is transformed, as well as the fact that the rhodanammonium absorbed by the superphosphate from it without any further reduction in value of the phosphate cannot be removed.

Wir haben beide Uebelstande vermieden durch Anwendung mineralischer Substanzen, welche Schwefelsäure aufsaugen und zu gleicher Zeit, ohne zerlegt zu werden, eine geringe Glühtemperatur aushalten.We have avoided both inconveniences by using mineral substances, which Soak up sulfuric acid and at the same time, without being decomposed, a low annealing temperature endure.

Als solche wendeten wir Infusorienerde und auch Flugasche an; es finden sich aber wahrscheinlich noch sonstige mineralische Stoffe (Infusorienerde nimmt 150 pCt. Schwefelsäure auf, ohne die erforderliche lockere Eigenschaft zu verlieren), welche für unsere Zwecke brauchbar sind.As such, we used infusoric soil and also fly ash; but they are likely to be found other mineral substances (infusor earth takes 150 pCt. sulfuric acid without losing the required loose quality), which are useful for our purposes are.

Die mit Schwefelsäure getränkte mineralische Substanz wird behufs Aufnahme des Ammoniaks aus dem Gase auf Gashorden ausgebreitet. Diese werden vor oder nach den zur Entfernung des Schwefels mit Eisenerz oder dergleichen beschickten Horden eingeschaltet und verbleiben in den Reinigungsapparaten, bis die Schwefelsäure nahezu gesättigt ist.The mineral substance soaked with sulfuric acid is used to absorb ammonia from the gases spread on gas cords. These are placed before or after the Sulfur with iron ore or the like charged hordes switched on and remain in the cleaning equipment until the sulfuric acid is almost saturated.

Sodann wird die Substanz ausgewechselt und, wenn sie rhodanhaltig ist, in einem geschlossenen, -mit Abzug für die entwickelten Gase versehenen eisernen Gefäfs oder Ofen einer gelinden Glühhitze ausgesetzt. Hierbei entweicht, falls Rhodanverbindungen und aufserdem ein geringer Schwefelsäureüberschufs vorhanden sind, Rhodanwasserstoffsäure und die theerigen Producte verkohlen. Bei Auslaugen der Masse und Eindampfen der Lauge erhält man ein sehr reines und schönes schwefelsaures Ammoniak; es kann aber auch unter Umständen die unausgelaugte Masse zur Düngerfabrikation verwendet werden, wenn Rhodangehalt nicht vorhanden ist. Die Leuchtkraft des Gases wird, wie dies die Erfahrung gelehrt hat, durch oben beschriebene Reinigungsmethode nicht beeinträchtigt.The substance is then exchanged and, if it contains rhodan, in a closed, - With a deduction for the evolved gases, iron vessel or furnace of a mild one Exposed to glowing heat. This escapes, if rhodan compounds and also a a slight excess of sulfuric acid are present, hydrothodic acid and the mineral products char. When the mass is leached out and the lye is evaporated, a very pure and beautiful sulfuric acid ammonia is obtained; however, under certain circumstances, the undrained mass can also be used for the manufacture of fertilizer if there is no rhodan content. The luminosity of the gas will be like this experience has taught, is not affected by the cleaning method described above.
