Zur Reinigung von Gasen der Kohlendestillation von unerwünschten Verunreinigungen sind mannigfache Verfahren in Benutzung und zur Benutzung vorgeschlagen worden. Insbesondere ist es bekannt, daß der in dem Gas enthaltene Schwefelwasserstoff durch Einleiten in Metallsalzlösungen,, wie z. B. in Form von aufgebrauchten Elektrolytlösungen galvanischer Elemente, gebunden werden kann.For cleaning gases from coal distillation from undesired impurities A variety of methods have been used and proposed for use. In particular, it is known that the in the Gas containing hydrogen sulfide by introducing it into metal salt solutions, such as. B. in shape of used electrolyte solutions of galvanic elements, can be bound.
ίο Ebenso ist es in bezug auf die Reinigung von Metallsalzlaugen bekannt, daß man Kupfer, anstatt dasselbe, wie es in der Regel geschieht, durch Eisen aus der Lauge zu entfernen, durch Schwefelwasserstoff fällen kann. Es ist auch bekannt, daß man aus Laugen, welche nebeneinander Kupfer und Zink enthalten, durch Schwefelwasserstoff das Kupfer allein fällen kann, wenn man dafür sorgt, daß die Lauge sauer gehalten wird, da Zink durch Schwefelwasserstoff aus saurer Lösung nicht niedergeschlagen wird.ίο It is the same with regard to the purification of Metallic brines have been known to use copper, instead of the same thing as is usually done, by removing iron from the lye, by precipitating hydrogen sulfide. It it is also known that alkaline solutions containing copper and zinc together the copper can be precipitated by hydrogen sulfide alone, if one sees to it that the Lye is kept acidic, since zinc cannot be replaced by hydrogen sulfide from acidic solution being knocked down.
Gemäß vorliegender Erfindung wird von diesen bekannten analytischen Methoden in der Weise Gebrauch gemacht, daß zwei Produktionszweige, welche auf Eisenhüttenwerken vielfach nebeneinander herlaufen, miteinander gekuppelt werden, um die lästigen Nebenprodukte des einen Produktionszweiges durch lästige Nebenprodukte eines anderen Produktionszweiges wechselseitig zu beseitigen und dabei außerdem wertvolles Metall zu gewinnen.According to the present invention, of these known analytical methods in the manner made use of that two branches of production, which on iron works often running next to each other, being coupled with each other to avoid the annoying by-products of one branch of production through annoying by-products of another branch of production to eliminate mutually and also to gain valuable metal in the process.
Die beiden Produktionszweige, welche derThe two branches of production which the
Erfindung gemäß miteinander gekuppelt werden sollen, sind der Koksofenbetrieb und der chlorierende Erzröstbetrieb. Beim Koksofenbetrieb entstehen Gase, welche Schwefelwasserstoff in mehr oder weniger großer Menge enthalten. Bei der Behandlung von Kiesabbränden durch ■ chlorierendes · Rösten entstehen sehr verdünnte Laugen, welche zu gleicher Zeit Kupfer- und Zinksalz enthalten, und welche, bevor sie in die Flußläufe geleitet werden dürfen, sowohl vom Kupfer als auch vom Zink befreit werden müssen. Wenn man nun die beim Koksofenbetrieb entstehenden Gase durch die Laugen leitet, so wird gleichzeitig eine Reinigung der Gase vom Schwefelwasserstoff und der Laugen vom Metallsalz erzielt. Es werden also die Produkte beider Betriebe von lästigen Beimengungen befreit. Auch analytisch ist bei diesem Verfahren immerhin das bemerkenswert, daß der in großer Verdünnung im Koksofengas enthaltene Schwefelwasserstoff noch imstande ist, die ebenfalls in großer Verdünnung enthaltenen Metallsalze aus der Lauge zu fällen.Invention to be coupled according to each other, are the coke oven operation and the chlorinating ore roasting plant. When operating the coke oven, gases are produced which contain hydrogen sulfide contained in more or less large quantities. When treating gravel burns due to ■ chlorinating · roasting, very dilute lyes are produced, which at the same time Contain copper and zinc salts, and which ones before they are discharged into the rivers must be freed from both copper and zinc. If you now have the When the coke oven is running through the lye, a Purification of gases from hydrogen sulphide and alkalis from metal salt achieved. It So the products of both companies are freed from annoying admixtures. Also analytically it is at least remarkable in this process that the in great dilution The hydrogen sulfide contained in the coke oven gas is still capable, which is also in great dilution to precipitate the metal salts contained in the lye.
Trotz der großen Verdünnung der Lauge besteht auch die Möglichkeit einer strengen ■ Scheidung des Kupfers vom Zink bei der Fällung. Beim Einleiten der Koksofengase in die Lauge in deren natürlichem sauren Zustande fällt zunächst nur Kupfer aus, wobei sich gleichzeitig die Lauge weiter an Säure anreichert. Die Kupferfällung kann so weit fortgesetzt werden, daß die Lauge schließlich praktisch frei von Kupfer ist. Wenn man die entkupferte Lauge neutralisiert, was beispielsweise mit kohlensaurem Kalk geschehenDespite the great dilution of the lye, there is also the possibility of a strict ■ Separation of copper from zinc during precipitation. When introducing the coke oven gases into the In its natural acidic state, lye initially precipitates only copper, whereby it becomes at the same time, the lye is further enriched in acid. The copper precipitation can go so far continue so that the liquor is finally practically free of copper. If the decuppered lye neutralizes what can happen, for example, with carbonate of lime
kann, und darauf in die neutrale Lauge weiter Koksofengas einleitet, so fällt das Zink als reines Schwefelzink aus. Man muß hierbei dafür Sorge tragen, daß die bei der Fällung des Zinks entstehende Säure im Maße ihres Entstehens abgestumpft wird, wodurch eine vollständige Abscheidung des Zinks ermöglicht wird. Wenn die Lauge noch andere Metalle enthält, wie z. B. Blei, Nickel, Kobalt usw., ίο so werden auch diese ausgefällt und können gewünschtenfalls getrennt abgeschieden werden.can, and then further introduces coke oven gas into the neutral liquor, the zinc falls as pure zinc sulphide. Care must be taken here that the The acid produced by the zinc is blunted to the extent that it is produced, thereby creating a complete Deposition of the zinc is made possible. If the lye also contains other metals, such as. B. lead, nickel, cobalt etc., ίο these are also precipitated and can, if desired, be deposited separately.
