Verfahren zur Behandlung vergorener Sulfitab ! auge vor dem Destillieren.
Wenn zwecks Herstellung von Alkohol ans Sulfitablauge die Lauge in bekannter Weise vergoren wurde, enthält sie eine verhältnismässig geringe Menge von Alkohol und eine viel grössere Menge von in der Lauge gelösten oder suspendierten, gemmiähnlichen oder gelatinösen organischen Stoffen, die der Lauge einen hohen Grad \on Viskosität und eine für die weitere Verarbettang sehr unangenehme Neigung zum Schäumen erf=teilen.
Die vorliegende Erfindung beruht auf der Beobachtung, dass diese Neigung zur Schaumbildung besonders durch den Gehalt der Lauge an Kohlensäure hervorgerufen wird, weshalb es sehr wichtig ist, vor Einbringen der Lauge in die Destillationsapparate die Kohlensäure so gründlich als möglich zu entfernen, um dadurch den Destillationsprozess zu er- leichteren un zu befördern.
EMI1.1
Kohlensäure dadurch entfernt wird, dass man die Lauge fein zerstäubt, z.
B. dadurch, dass sie unter beträchtlichem Druck kräftig gegen eine zweckmässige Prallvorrichtung getrieben oder durch irgend welches andere M) ttf't fein zerteilt wird, so dass die Kohlensäure teils infolge des Stosses und teils durch die Berührung der Flüssigkeitteilchen mit der Luft abgeschieden wird. Die fein zerteilte Flüssigkeit wird dann In einem geeigneten Behälter oder dgl. gesammelt, worin sich die Abscheidung der Kohlensaure fortsetzt, worauf erst-

Eine zur Durchführung des Verfahrens geeignete Vorrichtung kann aus einem Be- kälter \on beliebiger Form und Grosse bestehen, worin die Flüssigkeit belassen wird. nachdem sie vorher möglichst fein zerteilt worden ist. z. B. dadurch, dass sie gegen eine ge-

Method of treating fermented sulfites! eye before distilling.
If the liquor has been fermented in a known manner for the purpose of producing alcohol on the sulphite waste liquor, it contains a relatively small amount of alcohol and a much larger amount of dissolved or suspended, gemmi-like or gelatinous organic substances that give the liquor a high degree Viscosity and a tendency to foam, which is very unpleasant for further processing.
The present invention is based on the observation that this tendency to foam formation is particularly caused by the carbonic acid content of the lye, which is why it is very important to remove the carbonic acid as thoroughly as possible before introducing the lye into the distillation apparatus, in order to thereby stop the distillation process to facilitate and transport.
EMI1.1
Carbon dioxide is removed by finely atomizing the lye, e.g.
B. in that it is driven vigorously against a suitable impact device under considerable pressure or is finely divided by some other M) ttf't so that the carbonic acid is separated partly as a result of the impact and partly due to the contact of the liquid particles with the air. The finely divided liquid is then collected in a suitable container or the like, in which the separation of the carbonic acid continues, whereupon first

is promoted.
A device suitable for carrying out the method can consist of a container of any shape and size, in which the liquid is left. after it has been cut as finely as possible beforehand. z. B. by the fact that they
