Paraffin- und Theer-Industrie.Paraffin and tar industry.

Die Abfallschwefelsäure der Paraffin-, Petroleum- und Theerindustrie bildet, obgleich sie noch 50 bis 60 pCt. an wasserfreier Schwefelsäure enthält, ein werthloses und lästiges Abfallproduct, da sie wegen der aufgenommenen übelriechenden Verunreinigungen nur schwierig Verwendung findet.The waste sulfuric acid of the paraffin, petroleum and tar industries does, although it does 50 to 60 pct. of anhydrous sulfuric acid, a worthless and troublesome waste product, because it is difficult to use because of the ingested malodorous impurities.

Das nachstehende Verfahren gestattet es, unter Abscheidung dieser Verunreinigungen diese Säure technisch zu verwerthen.The following procedure allows these impurities to be separated out to utilize this acid technically.

Man füllt die Abfallsäure in eine verbleite Eisenpfanne, vermischt sie mit so viel Natriumoder Kaliumsulfat, dafs sich Bisulfat bilden kann, erhitzt und dampft ab.You fill the waste acid into a leaded iron pan, mix it with as much sodium or Potassium sulphate, which can form bisulphate, is heated and evaporated.

Es bildet sich Bisulfat und bald tritt ein Zeitpunkt ein, wo sich die Unreinigkeiten der Abfallsäure oben als dicker Theer abscheiden, welcher leicht vom Salz getrennt werden kann.Bisulphate is formed and soon there will be a point in time when the impurities of the Separate the waste acid at the top as thick tar, which can easily be separated from the salt.

Man läfst nun entweder das flüssige Bisulfat unten ab oder schöpft den Theer oben ab.Either drain the liquid bisulfate from below or skim off the tar from above.

Das Bisulfat wird alsdann in einem Flammenofen unter leichter Erhitzung bei Ueberschufs von Luft entwässert, wobei zugleich etwaige noch zurückgebliebene Unreinigkeiten zerstört werden, und kann dann beliebig verwendet werden.The bisulfate is then placed in a flame furnace with slight heating if there is an excess dehydrated by air, at the same time destroying any remaining impurities and can then be used as desired.

Fügt man der Abfallsäure aufser dem Natriumoder Kaliumsulfat noch ein anderes lösliches Sulfat, welches specifisch schwerer ist, z. B. Magnesiumsulfat, hinzu, so findet die Abscheidung des Theeres noch leichter statt.If you add another soluble acid to the waste acid in addition to sodium or potassium sulfate Sulfate, which is specifically heavier, e.g. B. magnesium sulfate is added, so the separation takes place the tar even more easily.

Statt der Abfallsäure bereits fertige Sulfate zuzusetzen, kann man auch Chlornatrium oder Chlorkalium anwenden und sich das Bisulfat aus der Abfallsäure selbst bilden lassen, wobei die entstehende Salzsäure in bekannter Weise durch geeignete Vorrichtungen zu gewinnen ist.Instead of adding ready-made sulfates to the waste acid, you can also use sodium chloride or Apply potassium chloride and let the bisulfate form from the waste acid itself, whereby the hydrochloric acid formed can be obtained in a known manner using suitable devices.
