Description

Verfahren zur Auswaschung von Schwefelwasserstoff aus Gasen. Im Hauptpatent ist ein Verfahren zum Auswaschen von Schwefelwasserstoff aus Gasen mittels alkalischer Eisenoxydlösungen beschrieben, das dadurch gekennzeichnet ist, daß man solche Lösungen verwendet, die als die Lösung vermittelnde organische Substanz Abfallstoffe von der Aufschließung von Holz, Stroh u. dgl. sowie Umw-andlhingsprodukte, namentlich Oxydationsprodukte dieser Abfälle, enthalten. Es hat sich nun gezeigt, daß man, bei diesem Verfahren statt der genannten Abfallstoffe der Pflanzenfasern verarbeitenden Industrien andere, gelöste Kohlehydrate enthaltende Abfall- oder Nebenprodukte von der Verarbeitung von Pflanzen oder Pflanzenteilen bzw. Umwandlungs-, wie Hydrolyse-und namentlich Oxydationsprodukte solcher Abfälle bzw. Gemische derartiger Produkte verwenden kann; als Beispiele seien Melasse und Schlempe bzw. deren Oxydationsprodukte genannt. Auch die mit Hilfe dieser Produkte erhaltenen alkalischen Eisenoxydlösungen können mit großem Vorteil zur Entschweflung verwendet werden, da sie sehr beständig und %virksam sind, wobei jedenfalls auch hier die vorhandenen Eiweißstoffe durch ihre Schutzkolloidwirku:rng oder sonstwie eine wichtige Rolle spielen. Beispielsweise verwendet man eine Lösung, die wie folgt hergestellt ist. In i cbm Wasser werden 2o kg zähflüssige Melasse und io kg Soda gelöst. Man leitet langsam Chlor ein, bis stärkere Schaumentwicklung eintritt und gibt hierauf 2 kg Eisenchlorid und etwa 30 kg Soda gelöst hinzu.Process for scrubbing hydrogen sulfide from gases. The main patent describes a process for scrubbing hydrogen sulfide from gases by means of alkaline iron oxide solutions, which is characterized in that such solutions are used which, as the solution-imparting organic substance, contain waste materials from the decomposition of wood, straw and the like, as well as conversion products , namely oxidation products of this waste. It has now been shown that, in this process, instead of the above-mentioned waste materials from the plant fiber processing industries, other waste or by-products containing dissolved carbohydrates from the processing of plants or plant parts or conversion products, such as hydrolysis and, in particular, oxidation products of such waste or Can use mixtures of such products; Examples are molasses and stillage and their oxidation products. The alkaline iron oxide solutions obtained with the help of these products can also be used with great advantage for desulphurisation, since they are very stable and effective, with the proteins present also playing an important role here due to their protective colloid effect or in some other way. For example, a solution is used which is prepared as follows. 20 kg of viscous molasses and 10 kg of soda are dissolved in 1 cbm of water. Chlorine is slowly introduced until more foam develops, and 2 kg of iron chloride and about 30 kg of dissolved soda are then added.
