Description
Verfahren zum Zerlegen von Gemischen von Stoffen mit verschiedenem Schmelzpunkt Es ist bekannt, daß man mit Hilfe von Zentrifugen, die auf einer bestimmten Temperatur gehalten werden, Gemische von zwei Stoffen oder Fraktionen mit verschiedenen Schmelzpunkten in flüssige und feste Anteile zerlegen kann.Method of breaking down mixtures of substances with various Melting point It is known that one with the help of centrifuges operating on a certain Temperature are maintained, mixtures of two substances or fractions with different Can break down melting points into liquid and solid parts.
Es wurde nun gefunden, daß man Stoffgemische gleichzeitig in mehrere Stoffe oder Fraktionen von verschiedenem Schmelzpunkt zerlegen kann, wenn man eine Zentrifuge benutzt, die auf verschiedene Temperaturen erhitzt ist, und gleichzeitig bei verschiedenen Temperaturen, je nach dem Schmelzpunkt der gewünschten Stoffe oder Fraktionen, flüssige Anteile aus der Zentrifuge entfernt. It has now been found that mixtures of substances can be converted into several at the same time Substances or fractions of different melting points can be broken down if you have a Used centrifuge heated to different temperatures and at the same time at different temperatures depending on the melting point of the desired substances or fractions, liquid components removed from the centrifuge.
Das Erhitzen der Zentrifuge geschieht in üblicher Weise, z. B. direkt durch heiße Luft oder andere Gase im Gegenstrom zu dem zu zentrifugierenden Gemisch. Man kann auch indirekt durch Dampf oder heiße Flüssigkeiten oder durch Zuführung elektrischer Energie die gewünschten Temperaturen einstellen. Besonders vorteilhaft ist es, die Wärme durch Hochfrequenzheizung zuzuführen. Es ist darauf zu achten, daß das Gehäuse keine niedrigere Temperatur hat als der an der betreffenden Stelle abzuziehende flüssige Stoff. The heating of the centrifuge is done in the usual way, for. B. directly by hot air or other gases in countercurrent to the mixture to be centrifuged. It can also be done indirectly by steam or hot liquids or by feeding electrical energy set the desired temperatures. Particularly beneficial is to supply the heat by high frequency heating. It is important to ensure, that the housing has no lower temperature than that at the point in question liquid substance to be withdrawn.
Die Zerlegung kann je nach dem Schmelz- oder Erstarrungspunkt der einzelnen Gemischbestandteile in jedem beliebigen Temperaturgebiet, auch weit unter o°, durchgeführt werden. The decomposition can take place depending on the melting point or the solidification point of the individual mixture components in any temperature range, even well below o °, to be carried out.
Das Verfahren kann dazu dienen, organische Verunreinigungen, z. B. Harz oder Pech, die bei der üblichen Destillation im Rückstand bleiben, im vorliegenden Fall aber in den niedrigerschmelzenden Fraktionen gelöst sind, von den rein zu gewinnenden hochschmelzenden Stoffen zu trennen. The method can serve to remove organic contaminants, e.g. B. Resin or pitch, which remain in the residue in the usual distillation, in the present However, if they are dissolved in the lower-melting fractions, from the pure ones to be recovered to separate high-melting materials.
Eine Ausführungsform des Verfahrens nach der Erfindung zeigt das folgende Beispiel. One embodiment of the method according to the invention shows this following example.
Beispiel Ein aus Erdöl abgeschiedenes Paraffingemisch wird mit einer Temperatur von 470 oben in eine kontinuierlich arbeitende Zentrifuge eingebracht, deren Trommel an der Eintrittsstelle auf der gleichen Temperatur gehalten wird. Der bei 470 schmelzende Teil des Paraffingemisches wird kurz nach der Eintrittsstelle von den festen Bestandteilen, die durch die Zentrifugalkraft an die Trommelwand geschleudert werden, getrennt und abgezogen. Der übrige Teil der Zentrifugentrommel wird auf folgenden Temperaturstufen gehalten: 47, 48, 50, 52, 53, 54, 551/2, 57, 58 und 600. In diesen zehn Temperaturstufen werden flüssige Fraktionen abgezogen, wodurch eine Zerlegung in Paraffine von verschiedenem Schmelzpunkt erreicht wird. Example A paraffin mixture separated from petroleum is mixed with a Temperature of 470 above introduced into a continuously operating centrifuge, whose drum is kept at the same temperature at the point of entry. The part of the paraffin mixture which melts at 470 is shortly after the entry point of the solid constituents that are attached to the drum wall by centrifugal force be thrown, separated and peeled off. The rest of the centrifuge drum is kept at the following temperature levels: 47, 48, 50, 52, 53, 54, 551/2, 57, 58 and 600. In these ten temperature levels, liquid fractions are withdrawn, whereby a breakdown into paraffins with different melting points is achieved.
