Description

Verfahren zur elektrischen Entwässerung bzw. Entsalzung von Rohölen und ähnlichen Emulsionen Gegenstand der Erfindung ist ein Verfahren zur elektrischen Entsalzung von Rohölen, z. B. Rohpetroleum. Bei der Erfindung kommt es darauf an, daß die elektrische Behandlung des Öles mit einer Beschallung, insbesondere durch Ultraschall, verbunden wird in der Weise, daß die akustische Behandlung entweder vor oder nach oder aber gleichzeitig mit der elektrischen Behandlung erfolgt.Process for the electrical dewatering or desalination of crude oils and similar emulsions The invention is a process for electrical Desalination of crude oils, e.g. B. crude petroleum. In the case of the invention, it is important that the electrical treatment of the oil with a sonication, in particular by Ultrasound, is connected in such a way that acoustic treatment either takes place before or after or at the same time as the electrical treatment.

Die Entwässerung bzw. Entsalzung von Rohölen, .insbesondere Rohpetroleum. in einem elektrischen Feld nach Art eines zur Reinigung von Gasen dienenden Elektrofilters ist bekannt. Ferner wurde schon vorgeschlagen, Hydrosole, z. B. Ö1-Wasserl:mulsionen, durch Ultraschall zu koagulieren.The dewatering or desalination of crude oils, especially crude petroleum. in an electric field in the manner of an electrostatic precipitator used for cleaning gases is known. It has also been proposed to use hydrosols, e.g. B. Oil-water: emulsions, to coagulate by ultrasound.

Diese beiden an sich bekannten Verfahren üben eine verschiedenartige Wirkung auf die zu trennenden Bestandteile des Hydrosols bzw. des Rohöles aus. Bei der elektrischen Entwässerung bzw. Entsalzung werden die in der Emulsion vorhandenen Wasserteilchen unter dem Einfluß des elektrostatischen Feldes zu größeren Tropfen zusammengeführt und auf diese Weise in dem Öl zum Absinken gebracht. Bei der akustischen Behandlung dagegen sind es die Ölteilchen, die auf die Beschallung reagieren, und zwar in der Weise, daB die koagulierten Ölteilchen in die Höhe steigen und sich so von den Wasserteilchen trennen.These two methods, known per se, practice a different one Effect on the components of the hydrosol or crude oil to be separated. at the electrical dewatering or desalination are those present in the emulsion Water particles turn into larger drops under the influence of the electrostatic field brought together and brought in this way to sink in the oil. With the acoustic Treatment, however, it is the oil particles that react to the sonication, and in such a way that the coagulated oil particles rise up and down so separate from the water particles.

In Erkenntnis dieser Vorgänge wird bei dem Verfahren nach der Erfindung die elektrische mit der akustischen Behandlung des Rohöles kombiniert.In recognition of these processes, the method according to the invention the electrical and acoustic treatment of the crude oil is combined.

Das Verfahren läßt sich ohne Schwierigkeit dem jeweiligen Charakter des zu entwässernden bzw. zu entsalzenden Rohöles anpassen. je nach Überwiegen des einen oder anderen Bestandteiles der Emulsion kann es vorteilhaft sein, die Beschallung entweder vor oder nach der elektrischen Behandlung erfolgen zu lassen. Es können aber auch Umstände vorliegen, die es ratsam erscheinen lassen, gleichzeitig sowohl elektrisch wie akustisch auf das Rohöl einzuwirken. Auf jeden Fall wird durch die kombinierte Behandlung gegenüber der bekannten Einfac lilxliandlung eine gesteigerte Wirkung und damit ein für die Raffinierung einwandfrei benutzbares entwässertes bzw. entsalztes Reinöl erzielt.The procedure can be adapted to the particular character without difficulty of the to be drained or to Adapt desalinating crude oil. depending on It can be advantageous to predominate one or the other constituent of the emulsion the sonication either before or after the electrical treatment allow. However, there may also be circumstances that make it advisable to act both electrically and acoustically on the crude oil at the same time. In any Case is made by the combined treatment compared to the known simple treatment an increased effect and thus one that can be used perfectly for refining dehydrated or desalinated pure oil achieved.

Wie (las Verfahren ausgeführt werden kann, ist für die Erfindung bedeutungslos. lies gilt sowohl für die Einrichtung zur elektrischen wie für die Einrichtung zur akustischen Behandlung des Rohöles.How (the method can be carried out is irrelevant to the invention. lies applies both to the device for electrical as well as to the device for acoustic treatment of crude oil.
