Description

Verfahren zur Gewinnung von reinem Schwefel aus Gasreinigermasse. Bei der bekannten Extraktion des Schwefels und Teeres aus der Gasreinigermasse vermittels Schwefelkohlenstoff und nachherigem Abdestillieren des Schwefelkohlenstoffes mit heißem Wasser gelingt es nicht, den Schwefel vom Teer gesondert zu erhalten. Nach vorliegender Erfindung wird nun die Trennung des Schwefels vom Teer dadurch erzielt, daß man den Schwefelkohlenstoff mit einer Lösung eines gegen Schwefelkohlenstoff, Teer und Schwefel indifferenten Salzes abdestilliert, deren Dichte größer als die des Teeres und kleiner als die des Schwefels ist.Process for the production of pure sulfur from gas cleaning mass. In the known extraction of sulfur and tar from the gas cleaning compound mediated Carbon disulfide and then distilling off the carbon disulfide with hot water fails to separate the sulfur from the tar. To According to the present invention, the separation of the sulfur from the tar is achieved by that the carbon disulfide with a solution of an anti-carbon disulfide, Tar and sulfur indifferent salt distilled off, the density of which is greater than that of tar and is smaller than that of sulfur.

Bei der Durchführung des Verfahrens wird die Extraktion des Teeres und Schwefels aus der Gasreinigermasse am besten in einem liegenden, rotierenden Extraktionsapparat bei entsprechender Temperatur vorgenommen, wobei aller freie Schwefel und der Teer sich im Schwefelkohlenstoff lösen und rlie zurückbleibende Gasreinigermasse nach dem bekannten Entzvanisieren wieder verwendungsfähig ist.When carrying out the process, the extraction of the tar is used and sulfur from the gas cleaning compound is best in a lying, rotating one Extraction apparatus made at the appropriate temperature, with all free The sulfur and tar dissolve in the carbon disulfide and rlie left behind Gas cleaning compound is reusable after the known de-galvanizing.

Die so erhaltene Lösung von Schwefel und Teer im Schwefelkohlenstoff läßt man gemäß der Erfindung in eine Destillierblase laufen, in welche vorher eine geeignete Menge einer wässerigen Lösung des gegenüber Schwefel, Teer und Schwefelkohlenstoff indifferenten und diese nicht lösenden Salzes, beispielsweise Aluminiumsulfat, gebracht worden ist, dessen Dichte größer als die des Teeres und kleiner als die des Schwefels .ist und beispielsweise 1 .3 beträgt. In der Destillierblase wird unter Rühren der Schwefelkohlenstoff abdestilliert, sodann das Rührwerk stillgesetzt und absetzen gelassen. Es bilden sich hierbei drei Schichten; die oberste enthält den Teer, die mittlere besteht aus der Salzlösung und die unterste besteht aus Schwefel, der nahezu teerfrei ist oder nur mehr wenig Teer enthält.The resulting solution of sulfur and tar in carbon disulfide is allowed to run according to the invention in a still into which a previously appropriate amount of an aqueous solution of the opposite to sulfur, tar and carbon disulfide indifferent and this non-dissolving salt, for example aluminum sulfate, brought whose density is greater than that of tar and less than that of sulfur .is and is, for example, 1 .3. In the still, the Carbon disulfide is distilled off, then the agitator is shut down and settled calmly. Three layers are formed here; the top one contains the tar that middle consists of the saline solution and the lowest consists of sulfur, which is nearly is tar-free or contains little tar.

Nach der durch Dekantieren herbeigeführten Trennung der Flüssigkeit vom Sch-,vefel kann derselbe gewünschten Falles durch Umkristallisieren einer weiteren Reinigung unter-,vorfen werden.After the liquid has separated by decanting vom Sch-, vefel can, if desired, by recrystallizing another Cleaning will be carried out.
