Description

Verfahren zur Gewinnung eines angereicherten, fließbaren Schwefelbreies Es ist bekannt, Schwefelwasserstoff oder solchen enthaltende Gase mit wäßrigen alkalischen Lösungen zu behandeln, die gewisse, Schwefelwasserstoff bindende Stoffe enthalten, und daß man durch eine Behandlung der Lösung mit Luft den aufgenommenen Schwefelwasserstoff zu elementarem Schwefel oxydieren kann. Dabei kann die Waschlösung noch Zusätze enthalten, welche die Einwirkung des Sauerstoffes bzw. die Oxydation des Schwefelwasserstoffes oder dessen Bindung verbessern. Als solche Zusätze haben sich z. B. Oxybenzole bewährt.Process for obtaining an enriched, flowable sulphurous pulp It is known to treat hydrogen sulfide or gases containing such with aqueous alkaline To treat solutions that contain certain substances that bind hydrogen sulfide, and that by treating the solution with air, the absorbed hydrogen sulfide can oxidize to elemental sulfur. The washing solution can also contain additives which contain the action of oxygen or the oxidation of hydrogen sulfide or improve its bond. As such additives z. B. Oxybenzenes proven.

Bei. dem genannten Verfahren entsteht eine wäßrige Suspension von feinverteiltem elementarem Schwefel. Um den Schwefel aus der Reaktionslösung zu entfernen, wurde bisher die Lösung filtriert. Dabei entsteht ein mehr oder weniger fest zusammenhängender Filterkuchen, der wegen seiner zähen tonähnlichen Struktur schwierig zu handhaben ist.At. the process mentioned results in an aqueous suspension of finely divided elemental sulfur. To get the sulfur out of the reaction solution remove, the solution was previously filtered. This creates a more or less firmly coherent filter cake, which because of its tough clay-like structure difficult to use.

Gemäß der Erfindung wird nun die Gewinnung des feinverteilten Schwefels aus den genannten Flüssigkeiten dadurch verbessert, daß man den beim Filtrieren der Flüssigkeit anfallenden Filterkuchen in Gegenwart eines Netzmittels (Emulgator) mechanischen Einwirkungen, etwa mittels eines Rührers, unterwirft, wobei der zähe Filterkuchen in eine leicht fließende Suspension ohne Wasserzugabe umgewandelt wird.According to the invention, the extraction of the finely divided sulfur is now from the liquids mentioned improved by the fact that the filtering process the filter cake produced by the liquid in the presence of a wetting agent (emulsifier) mechanical influences, for example by means of a stirrer, subject to the tough Filter cake is converted into an easily flowing suspension without the addition of water.

Der bei der Filtration der Schwefelsuspension anfallende Filterkuchen enthält in der Regel zwischen 40 und 60% elementaren Schwefel. Innerhalb dieses Bereichs braucht bei der Verflüssigung des Filterkuchens Wasser nicht zugesetzt zu werden, um den Kuchen in eine leicht bewegliche Flüssigkeit umzuwandeln, die durch Rohrleitungen unter Vermittlung von Pumpen od. dgl. weitertransportiert werden. kann. Die Behandlung des Filterkuchens wird durch die Verflüssigung erheblich erleichtert, so daß man beispielsweise den Schwefel leicht in einen Autoklav einfüllen kann, um geschmolzenen Schwefel bzw. Blockschwefel zu erzeugen.The filter cake resulting from the filtration of the sulfur suspension usually contains between 40 and 60% elemental sulfur. Inside this Area does not need water added to liquefy the filter cake to be able to transform the cake into an easily agile liquid that through pipelines with the mediation of pumps or the like. can. The treatment of the filter cake is made much easier by the liquefaction, so that, for example, the sulfur can easily be poured into an autoclave, to produce molten sulfur or block sulfur.

Andererseits ist es auch leicht möglich, den verflüssigten Schwefel durch Düsen zu zerstäuben in Gegenwart von heißen Gasen, die eine Verdampfung des Wassers bewirken, so daß ein stäubefähiges Schwefelpulver entsteht. Zur Verflüssigung des Schwefelkuchens bedient man sich vorteilhaft eines schnell laufenden Rührwerkes.On the other hand, it is also easily possible to use the liquefied sulfur atomized through nozzles in the presence of hot gases that cause evaporation of the Cause water, so that a powdery sulfur powder is produced. For liquefaction of the sulfur cake it is advantageous to use a fast-running agitator.
