Vorliegeride Erfindung betrifft ein Verfahren zur Abscheidung von Wasser aus Rohöl, Rohöldestillaten, Teeren (Gasteeren) o. dgl., besonders aus schweren Fraktionen. Das_Rohöl ist bekanntlich in seinem natürlichen Zustande eine Emulsion von Petroleum o. dgl. mit Wasser, Salz und Schmutz. Aber auch bei der Destillation des bereits entwässerten Rohöls mit Wasserdampf entsteht besonders bei denThe present invention relates to a method for separating water from crude oil, crude oil distillates, Tars (gasteeren) or the like, especially from heavy fractions. The_crude oil is as is well known, in its natural state, an emulsion of petroleum or the like with Water, salt and dirt. But also with the distillation of the already dehydrated crude oil with water vapor occurs especially with the
ίο schweren Fraktionen eine Emulsion, aus der sich ebenso wie aus dem natürlichen Rohöl das Wasser durch bloßes Wärmen nur sehr schwer und unvollkommen oder auch gar nicht abscheiden läßt. Dies hängt mit der starken Oberflächenspannung der suspendierten Teilchen der schweren Öle zusammen, die das Zusammenfließen derselben verhindert. Wird nun diese Oberflächenspannung durch mechanische Einwirkung von scharfgekörnten Materialienίο heavy fractions an emulsion that makes up just like water from natural crude oil is very difficult and imperfect by mere warming or can not be deposited at all. This is due to the strong surface tension the suspended particles of heavy oils together causing the confluence the same prevented. This surface tension is now due to mechanical action of sharp-grained materials
(z. B. scharfem Sand, feinen Glassplittern, abgeschreckter Schlacke, Eisenspänen u. dgl.) zerstört, so fließen die suspendierten Ölkügelchen zusammen, wodurch eine Trennung der beiden Flüssigkeiten, Öl und Wasser, erzielt wird. Dies kann entweder durch mechanische Mischung der erwärmten Emulsion mit scharfgekörnten Materialien vermittels Luft oder Rührwerk erfolgen, die Mischung kann aber auch in einem mit scharfgekörnten Materialien gefüllten erwärmten Filter stattfinden.(e.g. sharp sand, fine glass splinters, quenched slag, iron filings, etc.) destroyed, the suspended oil globules flow together, causing a separation of the both liquids, oil and water, is achieved. This can either be mechanical Mixing the heated emulsion with sharp-grained materials by means of air or Agitator done, but the mixture can also be done in one with sharp-grained materials filled heated filter take place.
Körnige Materialien sind wohl in der Ölindustrie ' verschiedentlich verwendet worden, doch immer nur zu dem Zweck, leichtere Verunreinigungen, wie insbesondere Schwebestoffe, einzuhüllen und zu Boden zu reißen. Weiter sind ähnliche Materialien, z. B. Sand, Ton, Mehl u. dgl., als Klärmittel verwendet worden, um beim Reinigen von Petroleum mittels Schwefelsäure die Teerprodukte mitzureißen und das Waschen des Petroleums mit Lauge und Wasser zu erleichtern oder ganz zu vermeiden. Granular materials were probably used in the oil industry 'several times, but only for the purpose lighter impurities, in particular suspended particles, wrap and tear down. Next are similar materials, e.g. B. sand, clay, flour and the like., Has been used as a clarifying agent in order to carry away the tar products when cleaning petroleum with sulfuric acid and to facilitate or avoid completely washing the petroleum with lye and water.
Demgegenüber wird nach vorliegendem Verfahren ausschließlich die Absonderung von Wasser aus wässerigen Emulsionen von Ölen, öldestillaten u. dgl. bezweckt und dieser Zweck durch Zerstörung der Oberflächenspannung der suspendierten Teilchen mittels scharfgekörnter Materialien erzielt.In contrast, according to the present procedure, only the segregation of Water from aqueous emulsions of oils, oil distillates and the like is intended and this purpose by destroying the surface tension of the suspended particles by means of sharp-grained Materials achieved.
