Verfahren zum Absorbieren von nitrosen Gasen.
Zur Absorption von nitrosen Gasen, wie solche z. B. im elektrischen Ofen erzeugt worden, mit suspendierten Basen bedient man sich bisher der Rieseltürme. Dieser Methode haftet indessen der technisch bedeutende Mangel an, dass sich in Zwischenräumen das Füllmaterials allmählich ein Schlamm absetzt, der eine wirksame Absorption zunehmend erschwert und schliesslich eine vollständige Verstopfung des Turmes herbeiführen kann.
Es wurde nun gefunden, dass sich die Absorption der nitroson Gase mittels Suspensionen
EMI1.1
im Dauerbetriebe Störungen eintreten, wie sie bei der Absorption mittels Kalkmilch in Rieseltürmen unvermeidlich sind. ausführen lässt, wenn man Apsorptionsmittel der ge- nannten Art in tropfbarer Form in feiner Verteilung dem Gasgemisch zuführt. Man erzielt bei dieser Arbeitsweise selbst bei Verwendung einer relativ wenig umfangreichen Apparatur eine ausserordentlich wirksame und glatte Absorption und kommt mit einer verhältnismässig
EMI1.2
Als Basen, die bei dem vorliegenden Verfahren Verwendung finden können, nennen wir insbesondere die Oxyde, Ilydroxyde oder Karbonate der alkalischen Erden oder der Magnesia usw.
Zur Herstellung der Absorptionsapparate können die billigsten Materialien, wie Eisen, Zement usw. dienen. Selbstverständlich kann man das vorliegende Verfahren sowohl zur Absorption der Gesamtmenge der z. B. aus dem elektrischen Ofen stammenden Stickoxyde verwenden, wie auch zur Bindung der letzten Anteile, welche nach Absorption der Hauptmenge derselben, z. H. durch Wasser in Form von Salpetersäure, in dem Gasgemisch zurückgeblieben sind.

Process for absorbing nitrous gases.
For the absorption of nitrous gases, such as such. B. has been generated in an electric furnace, with suspended bases one uses the trickle towers. However, this method has the technically significant deficiency that a sludge gradually settles in the gaps between the filling material, which makes effective absorption increasingly difficult and can ultimately lead to complete blockage of the tower.
It has now been found that the absorption of the nitrosone gases by means of suspensions
EMI1.1
In continuous operation disturbances occur, as they are unavoidable with the absorption by means of milk of lime in trickle towers. can be carried out when absorbent of the type mentioned is supplied to the gas mixture in fine distribution in drip form. With this method of operation, even when using a relatively small amount of equipment, an extremely effective and smooth absorption is achieved and a comparatively high level of absorption is achieved
EMI1.2
As bases which can be used in the present process, we mention in particular the oxides, Ilydroxides or carbonates of alkaline earths or magnesia, etc.
The cheapest materials such as iron, cement, etc. can be used to manufacture the absorption apparatus. Of course, you can use the present method both to absorb the total amount of z. B. from the electric furnace used nitrogen oxides, as well as to bind the last fractions, which after absorption of the main amount of the same, z. H. by water in the form of nitric acid in the gas mixture.
