Description

Gewinnung von Schwefel, Thiosulfaten und Sulfhydraten. lach dem Verfahren des Patents 407875 entfernt man Schwefelwasserstoff und Schwefeldioxyd aus den Abgasen der Clausöfen, indem man die Gase zwecks Bindung des Schwefeldioxyds zunächst mit Sulfhy dratlauge und darauf zwecks Bindung des Schwefelwasserstoffs mit Lösungen von Hydroxyden oder Sulfiden der Alkalien oder Erdalkalien wäscht.Production of sulfur, thiosulfates and sulfhydrates. laugh at the procedure of patent 407875 removes hydrogen sulfide and sulfur dioxide from the exhaust gases the Claus furnaces, by initially using the gases in order to bind the sulfur dioxide Sulfhy drate liquor and then for the purpose of binding the hydrogen sulfide with solutions washes from hydroxides or sulphides of alkalis or alkaline earths.

Es wurde nun gefunden, daß man die Gase zwecks Entfernung des Schwefeldioxyds mit Lösungen oder Aufschlemmungen der Sulfide der Alkalien oder Erdalkalien waschen kann, wobei, wie beim Verfahren des obengenannten Patents, gleichfalls eine Lösung von Thiosulfat, welche freien Schwefel in Suspensionen enthält, anfällt, während der Schwefelwasserstoff bei dem nachfolgenden Waschen im Waschsystem TI wie bei dein Verfahren des obengenannten Patents zu Sulfhydrat gebunden wird.It has now been found that the gases can be removed in order to remove the sulfur dioxide wash with solutions or slurries of sulphides of alkalis or alkaline earths can, whereby, as in the method of the above-mentioned patent, also a solution of thiosulfate, which contains free sulfur in suspensions, is obtained while the hydrogen sulfide in the subsequent washing in the washing system TI as in the process of the above patent is bound to sulfhydrate.

Enthalten die Clausöfenabgase Koh lens.äure, was fast immer der Fall ist, wenn der in den Clausöfen zur Verbrennung gelangende Schwefelwasserstoff durch Zersetzung von Schwefelcalcium oder Schwefelbarium mittels Kohlensäure gewonnen ist, so wird der Waschprozeß erheblich gestört. In diesem Falle hat es sich als zweckmäßig erwiesen, den kohlensäurehaltigen Schwefelwasserstoff vor dem Eintritt in die Clausöfen der Einwirkung von Sulfhydratlauge auszusetzen, wodurch die Kohlensäure gebunden wird.Do the Claus furnace exhaust gases contain carbon acid, which is almost always the case is when the hydrogen sulphide in the Claus furnaces is burned through Decomposition of calcium sulfur or barium obtained by means of carbonic acid is, the washing process is significantly disturbed. In this case it turned out to be Proven to be expedient, the carbonated hydrogen sulfide before entering to expose the Claus furnaces to the action of sulfhydrate liquor, which causes the carbonic acid is bound.
