Description

Verfahren zur Gewinnung von Schwefel--aus Schwefelwasserstoff oder solchen enthaltenden Gasen und Schwefeldioxyd. Durch Patent 30386z -ist ein Verfahren zur Gewinnung von Schwefel aus Schwefelwasserstoff bzw. solchen enthaltenden Gasen geschützt. Es besteht darin, daß man das mit der zur Überführung des Schwefelwasserstoffs in Schwefel erforderlichen Menge Luft oder Sauerstoff vermischte Gas auf poröse Kohle, wie Tier- oder Holzkohle, einwirken läßt.Process for obtaining sulfur - from hydrogen sulfide or such containing gases and sulfur dioxide. By patent 30386z - is a process for the extraction of sulfur from hydrogen sulfide or gases containing such protected. It consists in doing that with the conversion of the hydrogen sulfide in sulfur required amount of air or oxygen mixed gas on porous Allow coal, such as animal or charcoal, to act.

Es wurde nun gefunden, daß man eine vollständige Überführung des Schwefelwasserstoffs in Schwefel auch dadurch erzielen kann, daß man das Gas mit der erforderlichen Menge Schwefeldioxyd 2HZS+SOZ=2H20+3S vermischt auf poröse Kohle, wie Tier- oder Holzkohle, einwirken läßt. Die Reaktion zwischen den beiden Schwefelverbindungen erfolgt ohne äußere Wärmezufuhr so vollständig, daß die Abgase frei von Schwefelverbindungen sind. Der Schwefel scheidet sich unter Erwärmung, deren Höhe sich nach dem Gehalt des Gases an Schwefelverbindungen richtet, in der Kohle ab und kann daraus in bekannter Weise gewonnen werden.It has now been found that a complete conversion of the hydrogen sulfide can be achieved in sulfur can also be achieved by adding the required amount of gas Sulfur dioxide 2HZS + SOZ = 2H20 + 3S mixed on porous coal, such as animal or charcoal, can act. The reaction between the two sulfur compounds takes place without External heat supply so complete that the exhaust gases are free of sulfur compounds are. The sulfur separates under heating, the amount of which depends on the content of the gas aimed at sulfur compounds, in the coal and can from it in known Way to be won.

Die Reaktion zwischen Schwefelwasserstoff und Schwefeldioxyd bei Gegenwart poröser Kohle verläuft in der angegebenen Weise selbst bei geringem Schwefelwasserstoffgehalt des Gases und großer Gasgeschwindigkeit schnell und so vollständig, daß die Abgase vollkommen frei von Schwefelverbindungen sind. Werden die von Schwefelwasserstoff zu befreienden Gase zu Heizzwecken benutzt, wie z. B. Steinkohlengas, so tritt durch die Beimischung von Schwefeldioxyd keine Verminderung des Heizwertes ein.The reaction between hydrogen sulfide and sulfur dioxide in the presence porous coal proceeds in the manner indicated even with a low hydrogen sulfide content of the gas and high gas velocity quickly and so completely that the exhaust gases are completely free of sulfur compounds. Are those of hydrogen sulfide to be liberated gases used for heating purposes, such. B. coal gas, so occurs the addition of sulfur dioxide does not reduce the calorific value.

Es können so Schwefelwasserstoff oder Schwefelwasserstoff enthaltende Gase allgemein entschwefelt werden.It can thus contain hydrogen sulfide or hydrogen sulfide Gases are generally desulfurized.

Beispiel. 0,4 Volumprozent Schwefelwasserstoff enthaltendes Steinkohlengas wird mit 0,2 Volumprozent schwefliger Säure vermischt durch einen mit Holzkohle gefüllten Kessel geschickt. Den sich in der Holzkohle abscheidenden Schwefel gewinnt man dann nach erfolgter Sättigung der Kohle durch Extraktion. Das anhaftende Lösungsmittel wird durch Wasserdampf abgeblasen. Die Holzkohle ist dann wieder für die Entschwefelung weiterer Gasmengen verwendbar.Example. Hard coal gas containing 0.4 percent by volume of hydrogen sulfide is mixed with 0.2 percent by volume of sulphurous acid through one with charcoal sent filled kettle. The sulfur that is deposited in the charcoal is won then after the charcoal has been saturated by extraction. The adherent solvent is blown off by steam. The charcoal is then used again for desulfurization other gas quantities can be used.
