Description
Verfahren zur Reinigung von Roherdölen. In dem Patent 403134 ist ein Verfahren, zur Reinigung von Roherdölen u. dgl. mittels Alkalien beschrieben, welches darin besteht, daß man Salze bzw. Salzlösungen in einer solchen Konzentration anwendet, daß die Ver-, unreinigungen ausgeschieden bzw. ausgefällt und niedergeschlagen werden. Nach einer Ausführungsform werden außerdem Seifen bzw. seifenbildende Stoffe zur Reinigung benutzt.Process for cleaning raw oils. In the 403134 patent is a Process for cleaning crude oils and the like by means of alkalis described, which consists in using salts or salt solutions in such a concentration that that the impurities, impurities are excreted or precipitated and knocked down. According to one embodiment, soaps or soap-forming substances are also used Cleaning used.
Es hat sich nun gezeigt, daß man bei dieser Ausführungsform, die sich als besonders zweckmäßig erwiesen hat, die Salze entbehren kann, wenn die Alkalien in solcher Menge und in solcher Konzentration angewandt werden, daß unter Mitwirkung von Seifen hierdurch eine Ausscheidung bzw. Ausfällung und Niederschlagen der Verunreinigungen erfolgt. Man erzielt hierbei die Abscheidung eines praktischen, seifenfreien, gereinigten öles.It has now been shown that in this embodiment, the has proven to be particularly useful, the salts can be dispensed with, if the alkalis in such an amount and in such a concentration that with cooperation of soaps, this causes the impurities to be eliminated or precipitated and deposited he follows. This results in the separation of a practical, soap-free, purified one oils.
Praktisch verwendet man größere Alkalimengen von starker Konzentration. Man setzt das Alkali zweckmäßig nach der Behandlung mit Seifen zu. Man kann aber auch das Alkali ganz oder teilweise zusammen mit der Seife verwenden. Ausführungsbeispiel: i oo kg Mineralöldestillat werden bei Zimmerwärme mit i o kg einer i oproz. stark alkalischen Monopolseifenlösung innig vermengt und sodann unter ständigem Rühren nach und nach mit io 1 starker Natronlauge (39° B6) versetzt. Man fügt sodann zwecks tunlichst scharfer Trennung der Schichten noch 5 bis i o kg Wasser hinzu, rührt um und überläßt das Gemisch der Ruhe, wobei sich unten klare Lauge, in der Mitte die Verun= reinigungen und oben gereinigtes Öl absetzt. Letzteres wird nötigenfalls von etwa noch anhaftendem freien Alkali und Seifen durch Waschen befreit.In practice, larger amounts of high concentration alkali are used. The alkali is expediently added after the treatment with soaps. But you can also use the alkali in whole or in part together with the soap. Embodiment: i oo kg of mineral oil distillate are produced at room temperature with i o kg of an i oproz. strong alkaline monopole soap solution intimately mixed and then with constant stirring little by little 10 1 strong sodium hydroxide solution (39 ° B6) was added. One then adds for the purpose As sharp as possible separation of the layers, 5 to 10 kg of water are added and the mixture is stirred around and leaves the mixture to rest, with clear lye at the bottom, in the middle the impurities and the oil cleaned above settles. The latter will if necessary freed of any free alkali and soaps still adhering by washing.
Die Lauge kann wieder verwendet werden, die mittlere seifenhaltige Schicht dient als wasserlösliches öl, oder die darin enthaltenen Seifen werden regeneriert und für neue Raffin.ationen benutzt.The lye can be used again, the middle one can be used with soap Layer serves as a water-soluble oil, or the soaps contained in it are regenerated and used for new refinements.
Als Rohstoffe für das Verfahren kommen, außer Roherdölen auch Erzeugnisse der Erdöl-, Braunkohlen- und Paraffinindustrie in Frage.In addition to crude oils, products are also used as raw materials for the process the oil, lignite and paraffin industries in question.
Das Verfahren läßt sich natürlich auch auf solche Erzeugnisse anwenden, die bereits nach .anderen Methoden vorgereinigt sind, z. B. auch für die mit Schwefelsäure behandelten Öle. Als Zusätze für die Raffination kommen Seifen, seifenartige bzw. seifenbildende Stoffe und ähnliche Erzeugnisse in; Betracht.The process can of course also be applied to such products which have already been pre-cleaned according to other methods, e.g. B. also for those with sulfuric acid treated oils. Soaps, soap-like or soap-like additives are used as additives for refining. soap-forming substances and similar products in; Consideration.
