  Verfahren zur Abscheidung von Wasser oder wässerigen Lösungen aus Erdöl-oder anderen Ölemulsionen. 



   Die Schwierigkeiten der Abscheidung von Wasser aus Erdö'-oder anderen Ölemulsionen suchte man bis jetzt dadurch zu überwinden, dass man die Emulsionen längere Zeit erwärmte, wodurch jedoch in den meisten Fällen, sogar bei sehr langem Abstehen, nur eine unvollständige Abscheidung der wässerigen Phasen erreicht wurde. 



   Der Gegenstand der vorliegenden Erfindung beruht auf der Erkenntnis, dass erst bei höherer Temperatur, die nur bei   Überdruck   zu erzielen ist, eine solche Verminderung 
 EMI1.1 
 der wässerigen Phase ermöglicht. 



   Dieser Zustand verminderter Viskosität wird dadurch erreicht, dass die Emulsion in geschlossenen Gefässen auf die Temperaturen über   ioo"C   unter mindestens   I   Atm. 



  Überdruck erwärmt, einige Zeit in diesem Zustand unterhalten, hierauf abgekühlt wird, worauf die getrennten Phasen nacheinander abgelassen werden können. 



   Die Erwärmung kann entweder durch Erhitzen in der Blase oder dadurch erfolgen, dass Wasserdampf unter Überdruck in das Reaktionsgefäss eingeführt wird. Die zur Trennung erforderliche Zeit ist von der Beschaffenheit der Emulsion und von der Grösse der suspen-   dierten Wassertei1chen abhängig.   Die Zeit des Abscheidens kann man verkürzen, wenn bei verminderter Viskosität die Emulsion durchgerührt und hierauf der Inhalt des Behälters absetzen gelassen wird. 



   Ausführungsbeispiel : Eine frisch aus dem Schachte gewonnene Rohölemulsion wird durch vier Stunden bei 8 Atm. Überdruck ohne Rühren erwärmt. Nach dieser Zeit ist die Trennung der Rohölemulsion in   56"/,) Salzlösung   und 440/0 Rohöl vollzogen. Ein Erwärmen auf 5-6 Atm. führt auch zum Ziele, erfordert aber zur Trennung unter   Riihren   eine Arbeitszeit von etwa 10 Stunden.

  Process for separating water or aqueous solutions from petroleum or other oil emulsions.



   The difficulties of separating water from petroleum or other oil emulsions have hitherto been attempted by heating the emulsions for a longer period of time, which in most cases, even when standing for a very long time, only achieves incomplete separation of the aqueous phases has been.



   The subject matter of the present invention is based on the knowledge that such a reduction is only achieved at a higher temperature, which can only be achieved at overpressure
 EMI1.1
 the aqueous phase allows.



   This state of reduced viscosity is achieved by bringing the emulsion in closed vessels to temperatures above 100 "C below at least 1 atm.



  Heated overpressure, maintained in this state for some time, then cooled, whereupon the separate phases can be drained off one after the other.



   The heating can take place either by heating in the bubble or by introducing steam into the reaction vessel under excess pressure. The time required for separation depends on the nature of the emulsion and the size of the suspended water particles. The separation time can be shortened if the emulsion is stirred through at a reduced viscosity and the contents of the container are then allowed to settle.



   Exemplary embodiment: A crude oil emulsion freshly obtained from the shaft is heated for four hours at 8 atm. Heated overpressure without stirring. After this time, the separation of the crude oil emulsion into 56% salt solution and 440/0 crude oil is complete. Heating to 5-6 atm. Also works, but requires a working time of about 10 hours for separation with stirring.
