Description
Verfahren zur Entfernung von Schwefelwasserstoff und anderen Schwefelverbindungen aus Kohlendestillationsgasen u. dgl. Die Erfindung bezieht sich auf die Entfernung von Schwefelwasserstoff und anderen Schwefelverbindungen und Verunreinigungen aus Gasen, insbesondere Kohlendestillationsgasen, mittels Waschflüssigkeiten, die Metalle der Zinngruppe der qualitativen Analyse enthalten, beispielsweise einer alkalischen Lösung von Arsen-Schwefel-Sauerstoff-Verbindungen.Process for removing hydrogen sulfide and other sulfur compounds from coal distillation gases and the like The invention relates to removal of hydrogen sulfide and other sulfur compounds and impurities Gases, in particular coal distillation gases, by means of washing liquids, the metals of the tin group of the qualitative analysis, for example an alkaline one Solution of arsenic-sulfur-oxygen compounds.
Das eingangs kurz gekennzeichnete Waschverfahren ist in neuerer Zeit allgemein mit dem Namen Thylox-Verfahren bezeichnet worden.The washing process briefly identified at the beginning is more recent generally known as the Thylox process.
Es wurde gefunden, daß die Durchführung des Thylox-Verfahrens wesentlich dadurch erleichtert werden kann, daß der Waschlösung geringe Mengen von Mangan- oder Kupfersalzen zugesetzt werden. Die durch Zusatz derartiger Verbindungen erreichte Verbesserung des Waschverfahrens wirkt sich sowohl hinsichtlich der Auswaschung der Schwefelverbindungen aus dem Gas wie hinsichtlich der Regenerierung der ausgebrauchten Waschlösung durch Oxydation (Einblasen von Luft) unter Bildung von wertvollem e1& mentarem Schwefel günstig aus.It has been found that performing the Thylox process is essential this can be facilitated by adding small amounts of manganese to the washing solution or copper salts are added. The one achieved by adding such compounds Improvement of the washing process affects both in terms of leaching the sulfur compounds from the gas as with regard to the regeneration of the exhausted ones Washing solution through oxidation (blowing in air) with the formation of valuable e1 & mentary sulfur.
Bei der praktischen Anwendung des den Gegenstand der Erfindung bildenden Verfahrens, der Waschflüssigkeit beim Thylox-Verfahren Mangan- oder Kupfersalze zuzusetzen, wurde beispielsweise festgestellt, daß in einer Thylox-Anlage, in der etwa 350 cbm Waschflüssigkeit im Umlauf war, durch Zusatz von 25 kg Manganchlorür die Auswaschung des Schwefelwasserstoffs aus dem Gase von etwa 9o °/a auf praktisch roo °/o stieg.In the practical application of the method forming the subject of the invention of adding manganese or copper salts to the washing liquid in the Thylox process, it was found, for example, that in a Thylox plant in which about 350 cbm of washing liquid was in circulation, by adding 25 kg Manganese chloride for the leaching of hydrogen sulphide from the gas rose from about 90 per cent. To practically 100 per cent.
Die Anwendung des Verfahrens gemäß der Erfindung gibt die Möglichkeit, die Wasch-und Regenerierapparatur des Thylox-Verfahreis ganz erheblich zu verkleinern, wodurch gleichzeitig sowohl die Anlagekosten wie auch die für das Umwälzen der Waschlösung und für die Verdichtung der Oxydationsluft aufzuwendenden Betriebskosten wesentlich sinken.The application of the method according to the invention gives the possibility to significantly reduce the size of the washing and regeneration equipment of the Thylox process, which at the same time both the plant costs and those for circulating the washing solution and operating costs to be expended for the compression of the oxidizing air sink.
Anstatt den Waschlösungen Mangan- oder Kupfersalze, beispielsweise Manganchlorür, zuzusetzen, kann man auch die Bildung der anscheinend als Katalysatoren wirkenden Metallverbindungen in der Waschlösung dadurch hervorbringen, daß gewisse, mit der Waschflüssigkeit in Berührung kommende Teile der Waschapparatur aus Kupfer- bzw. kupfer- oder manganhaltigen Legierungen hergestellt werden. Es wurde gefunden, daß beispielsweise die unvermeidbare geringe Auflösung von Monelmetall genügt, um in die Waschlösung eine als Katalysator hinreichende Menge Kupfer einzuführen. Wie aus dem Obigen ersichtlich, ist die zur Durchführung des Verfahrens gemäß der Erfindung erforderliche Menge Mangan- oder Kupferverbindungen außerordentlich gering. Infolgedessen tritt auch eine merkbare Verunreinigung des bei der Regenerierung der Waschflüssigkeit entstehenden elementaren Schwefels durch gleichieitig gebildete unlösliche Metallverbindungen praktisch nicht ein, . wie auch der Zusatz frischer Metallverbindungen -zu der Lösung zum Zwecke, den Gehalt der Lösung an wirksamen Katalysatoren zu erhalten, sehr gering ist.Instead of the washing solutions manganese or copper salts, for example Manganese chloride, adding one can also apparently act as a catalyst effective metal compounds in the washing solution by the fact that certain, parts of the washing apparatus made of copper that come into contact with the washing liquid or alloys containing copper or manganese. It was found, that, for example, the inevitable low dissolution of Monel metal is sufficient to to introduce a sufficient amount of copper as a catalyst into the washing solution. As from the above it can be seen that for carrying out the method according to the invention required amount of manganese or copper compounds extremely small. Consequently There is also noticeable contamination of the washing liquid when the washing liquid is regenerated elemental sulfur formed by insoluble metal compounds formed at the same time practically not a,. as well as the addition of fresh metal compounds to the solution for the purpose of maintaining the effective catalyst content of the solution, very low is.
