(Oesterr.-Schlesien).(Eastern Silesia).
Das Verfahren besteht wesentlich darin, dafs man den. Schwefelwasserstoff bei gleichzeitiger Einwirkung von Hitze durch Sulfate von Alkalien oder alkalischen Erden streichen läfst, wobei der Sauerstoff dieser Salze sich mit dem Wasserstoff des Schwefelwasserstoffes zu Wasser verbindet, während das betreffende Schwefelmetall zurückbleibt und freier Schwefel abfliefst. Durch darauf folgendes Einblasen von atmosphärischer Luft bei fortdauernder Einwirkung von Hitze kann das Schwefelmetall wieder zu Sulfat oxydirt werden, welches neuerlich Verwendung findet. The main thing is that the Hydrogen sulfide at the same time Can be exposed to heat from sulphates of alkalis or alkaline earths, the oxygen of these salts and the hydrogen of the hydrogen sulphide to form water connects, while the sulfur metal in question remains and free sulfur flows off. By subsequently blowing in atmospheric air with continued exposure The sulfur-metal can be oxidized again by heat to sulfate, which is used again.
Bei der praktischen Durchführung dieses Processes, welcher zur Verwerthung der bei
der Sodafabrikation nach dem Leblanc'schen Verfahren sich ergebenden Rückstände besondere
Vortheile bietet, wird der zu verarbeitende Schwefelwasserstoff durch ein zur Rothglut erhitztes,
vorzugsweise1 mit Gypsstücken gefülltes Röhrensystem geleitet, dessen anderes Ende mit
einem Condensator für den flüssigen Schwefel in Verbindung steht. Die hierbei stattfindende
Reaction wird durch folgende Gleichung ausgedrückt :
Ca S O4 + 4 H2 S — Ca S ■+- 4 H2 O + 4 S. In the practical implementation of this process, which offers particular advantages for the recovery of the residues resulting from the production of soda according to the Leblanc method, the hydrogen sulfide to be processed is passed through a system of pipes, preferably one filled with pieces of gypsum, which is heated to a red ember and preferably filled with pieces of gypsum a condenser for the liquid sulfur is in connection. The reaction that takes place is expressed by the following equation:
Ca S O 4 + 4 H 2 S - Ca S ■ + - 4 H 2 O + 4 S.
Um bei dem Processe'jede Möglichkeit einer Verbindung des freiwerdenden Sauerstoffes mit dem Schwefel hinten anzuhalten, leitet man beständig einen Ueberschufs an Schwefelwasserstoff zu, so dafs jedes Sauerstoffatom in statu nascendi immer eine genügende Menge der gröfsere Affinität besitzenden Wasserstoffatome vorfindet. Der auf diese Weise in die Condensationskammern gelangte Schwefelwasserstoff wird wieder in die zur Production dieses Gases dienende Lauge geleitet und so weiter verarbeitet. In order to prevent any possibility of a connection between the released oxygen and the sulfur in the process, an excess of hydrogen sulfide is constantly supplied, so that every oxygen atom in statu nascendi always finds a sufficient quantity of the hydrogen atoms with greater affinity. The hydrogen sulphide that got into the condensation chambers in this way is fed back into the liquor used for the production of this gas and processed further.
Ist sämmtlicher Gyps zu Schwefelcalcium reducirt, so leitet man das zu zersetzende Schwefelwasserstoffgas durch einen nebenstehenden Apparat gleicher Einrichtung, in welchem sich der Procefs in gleicher Weise vollzieht, während man in den ersten Apparat atmosphärische Luft einbläst, um ■ das Schwefelcalcium wieder zu Calciumsulfat zu oxydiren.When all the gypsum is reduced to calcium sulphide, that which is to be decomposed is passed on Hydrogen sulfide gas through an adjacent apparatus of the same facility in which the process takes place in the same way, while the first apparatus is atmospheric Air is blown in to re-oxidize the calcium sulphate to calcium sulphate.
Behufs Verwerthung der bedeutenden Menge von Wärme, welche bei diesem Oxydationsprocesse frei wird, sind die beiden im Vorstehenden erwähnten zusammengehörigen Röhrensysteme so mit einander verbunden, dafs die in einem Röhrensystem freiwerdende Wärme das Alkali- oder Erdalkalisulfat im anderen Röhrensystem erhitzt.For the purpose of utilizing the considerable amount of heat produced in this process of oxidation becomes free, are the two pipe systems mentioned above that belong together so connected with one another that the heat released in one system of pipes dissolves the alkali or alkaline earth sulphate in the other Tubular system heated.
