Description

Nutzbarmachung der Endgase von Schwefeisäurekonzentrationsanlagen. Schwefelsäurekonzentrationsanlagen, bei denen die Eindampfung der Kammersäure durch direkte Feuerung erfolgt, z. B. die Anlage nach System Gaillard, liefern ein Endgas, das Stickstoff, Sauerstoff, Kohlensäure, Wasserdampf, Schwefelsäure und unter Umständen auch schweflige Säure enthält. Die Wiedergewinnung = der -durch die Endgase mitgeführten Schwefelsäure läßt sich nach %-erschiedenen Verfahren bewerkstelligen, welchen gemeinsam ist, daß sie nur die kondensierbaren Bestandteile der Endgase, nämlich Wasserdampf und Schwefelsäure, zurückhalten und auch diese nicht vollständig. Man erhält so die mitgerissene Schwefelsäure als mehr oder weniger wasserhaltige Kondensatsäure zurück, die zur Weiterverwendung unter neuem Heizmaterialaufwand eingedampft werden muß.Utilization of the end gases from sulfuric acid concentration systems. Sulfuric acid concentration systems, in which the evaporation of the chamber acid by direct firing takes place, e.g. B. the system according to the Gaillard system, deliver an end gas, the nitrogen, oxygen, carbonic acid, water vapor, sulfuric acid and possibly also contains sulphurous acid. The recovery = that entrained by the tail gases Sulfuric acid can be done by% different processes, some of which are common is that they only contain the condensable components of the end gases, namely water vapor and sulfuric acid, hold back and also not completely. You get so the entrained sulfuric acid as a more or less water-containing condensate acid back, which are evaporated for further use using new heating material got to.

Im Gegensatz hierzu bewirkt das vorliegende Verfahren die quantitative Wiedergewinnung der Schwefelsäure und schwefligen Säure in Form von Kammersäure sowie außerdem die Ausnutzung des Wasserdampfes zur Schwefelsäureherstellung, ohne daß hierzu eine besondere Apparatur oder ein zusätzlicher Kraftaufwand erforderlich wäre. Um dies zu erreichen, werden die Endgase auf dem kürzestmöglichen Wege in geeigneter Weise in die Kammern einer Schwefelsäureanlage eingeleitet, woselbst Schwefelsäure, schweflige Säure und Wasserdampf restlos in den Kammerprozeß eingehen, während der Rest der Konzentrationsendgase mit den -Kamanerendgasen abgeführt wird.In contrast, the present method effects the quantitative one Recovery of sulfuric acid and sulphurous acid in the form of chamber acid as well as the use of steam for sulfuric acid production, without that this requires special equipment or additional effort were. In order to achieve this, the end gases are in the shortest possible way in suitably introduced into the chambers of a sulfuric acid plant, where it is itself Sulfuric acid, sulphurous acid and water vapor enter the chamber process completely, while the rest of the concentration end gases are discharged with the -Kamaner end gases.
