aus nitrosen Gasen.from nitrous gases.
Patentiert im Deutschen Reiche vom 4. Februar 1906 ab. Patented in the German Empire on February 4, 1906.
Die vorliegende Erfindung betrifft die Kondensation sogenannter nitroser Gase, wie sie beispielsweise bei der Behandlung von atmosphärischer Luft mit elektrischen Entladungen erhalten werden, zu Salpetersäure von handelsfähiger Konzentration.The present invention relates to the condensation of so-called nitrous gases, such as them for example in the treatment of atmospheric air with electrical discharges obtained, to nitric acid of marketable concentration.
Das neue Verfahren besteht darin, daß man den Reaktionsgasen nach Verlassen der elektrischen Entladungen Wasser oder Wasser dampf in solcher Menge zusetzt, daß sich bei einer Abkühlung bis auf ioo° noch keine Säure aus den Gasen ausscheiden kann, weil man damit die Möglichkeit gewinnt, bis zur Abkühlung der Gase bis auf etwa ioo° metallene Kühleinrichtungen zu verwenden, welche sehr viel wirksamer und billiger sind· als Kühleinrichtungen aus Steinzeug.The new process consists in that one of the reaction gases after leaving the electrical Discharges Water or water vapor is added in such an amount that, when it cools down to 100 °, none Acid can be eliminated from the gases because it gives you the opportunity to up to Cooling of the gases down to about ioo ° to use metal cooling devices, which are much more effective and cheaper than cooling devices made of stoneware.
Dies ist wegen der geringen Haltbarkeit von Steinzeugapparaten bei TemperaturenThis is because of the low durability of stoneware appliances at temperatures
ao. über ioo° ein ganz wesentlicher Fortschritt, der noch dadurch an Bedeutung gewinnt, daß man bei dieser Arbeitsweise natürlich auch keiner Reaktionsgase von hohem Stickoxydgehalt bedarf. Letzteres hat den doppelten Vorteil, daß erstens diese dünneren Gase bei der elektrischen Luftverbrennung mit bedeutend besserer Wattausbeute hergestellt werden können als höherprozentige, daß aber auch zweitens die Gase bei ihrer Kondensation nur noch so wenig Stickstoffoxyde enthalten, daß die ausgeschiedene Säure kein Stickstoffdioxyd mehr löst, so daß die so gewonnene Säure auch praktisch frei von gelösten Stickstoffoxyden ist.ao. a very significant advance via ioo °, which becomes even more important as a result, that one of course also no reaction gases with a high nitrogen oxide content with this method of operation requirement. The latter has the double advantage that, firstly, these thinner gases are used in electrical air combustion can be produced with significantly better wattage than higher percentage that but also, secondly, the gases condense only so little nitrogen oxides contain that the precipitated acid no longer dissolves nitrogen dioxide, so that the so obtained Acid is also practically free of dissolved nitrogen oxides.
