Description
von Schwefelsäure.of sulfuric acid.
Patentiert im Deutschen Reiche vom 10. Januar 1913 ab.Patented in the German Empire on January 10, 1913.
Es hat sich gezeigt, daß bei der Herstellung von Schwefelsäure mit Hilfe des Turmsystems durch Einschaltung eines mit Füllmaterialien versehenen Turmes zwischen denjenigen Türmen, die als Reaktionstürme dienen, und denjenigen, die als Gay-Lussac-Apparate arbeiten, Verbesserungen in der Arbeitsweise des betreffenden Systems entstanden sind. Der Zweck des eingeschalteten Turmes ist die Vermehrung der Kondensationsgelegenheit für die von dem Gasstrom mitgerissenen Schwefelsäur enebel, besonders bei sehr schneller Gasbewegung, also bei verstärktem Betriebe. Die Kondensationswirkung des Turmes kann durch Berieselung mit gewöhnlicher, d. h. in diesem Falle schwächerer als in den Gay-Lussac-Türmen verwendeter Schwefelsäure wesentlich erhöht werden. Die Vorteile eines solchen eingeschalteten Turmes bestehen in der Ersparnis an Salpetersäure und in der Erhöhung der Produktion, ganz einerlei, ob das Turmsystem ganz oder teilweise. Koks oder Prismensteine, Gloverringe o. dgl. als Füllmaterial hat. Unter Umständen kann es zweckmäßig sein, den Turm auch mit nitroser Schwefelsäure zu berieseln, um letzte Reste von Schwefeldioxyd zu oxydieren.It has been shown that in the production of sulfuric acid with the help of the tower system by the inclusion of a filling material provided tower between those towers that serve as reaction towers and those that serve as Gay-Lussac apparatus work, improvements have been made in the operation of the system in question. Of the The purpose of the activated tower is to increase the condensation opportunity for the sulfuric acid mist entrained by the gas flow, especially with very rapid gas movement, so with reinforced operations. The condensation effect of the tower can be achieved by sprinkling with ordinary, i.e. H. in this Case of weaker sulfuric acid than that used in the Gay-Lussac Towers is significantly increased will. The advantages of such an activated tower are the savings in nitric acid and in increasing production, it doesn't matter whether the tower system completely or partially. Coke or prism stones, glover rings or the like. Has as filler material. Under In some circumstances it may be useful to sprinkle the tower with nitrous sulfuric acid, to oxidize the last remains of sulfur dioxide.
