Description

Verfahren zum Raffinieren von Erdölen Durch (las Patent 4C)2 840 ist ein Verfahren zum Raffinieren von Erdölen geschützt. Es besteht darin, daß man dieselben mit Fluorwasserstoff behandelt, dem man Metallhalogenide zusetzen kann.Process for Refining Petroleum Is Through (read Patent 4C) 2,840 a process for refining petroleum protected. It consists in being able to do the same treated with hydrogen fluoride to which metal halides can be added.

Es wurde nun gefunden, daß man an Stelle von Metallhalogeniden auch Metalloidhalogenicle vorteilhaft verwenden kann. Das Öl wird mit Flußsäure, der geringe Mengen eines Metalloidhalogenids zugesetzt sind, zur Reaktion gebracht. Nach etwa 2 Stunden ist der Reinigungsprozeß beendet und die Öle können destilliert werden. Da die Flußsäure bereits bei 2o° siedet, kann der Hauptteil der Flußsäure leicht abgetrieben und gleich für eine neue Raffination verwendet werden. Wird ein gasförmiges Metalloidhalogenid zugesetzt, so wird auch dieses im selben Arbeitsgang wiedergewonnen. Der Rest der Flußsäure bildet mit den ungesättigten Bestandteilen des Öles und den Pol_vmerisationsprodukten Doppelverbindungen, die erst bei der Destillation der- Öle wieder zerfallen. Um auch diesen Teil der Flußsäure wieder zu gewinnen, kann es sich als vorteilhaft erweisen, das Öl durch haliumfluorid zu destillieren. Die freie Flußsäure wird dann quantitativ gebunden, und es resultieren neutrale Öle, die nicht mehr nachgewaschen zu werden brauchen. Beispiel I Erdöl wird 4 Stunden bei Zimmertemperatur mit 4 °(" Flußsäure und 2 °/, Borfluorid behandelt. Die Bromzahl des Öls sinkt dabei von 2,2 auf o,oi. Beispiel e Eine Erdölfraktion 5o bis 225° bei 3 min wird bei Zimmertemperatur 2 Stunden mit d. % Flußsäure und i °/" PF, behandelt. Die Bromzahl sinkt von 2,2 auf o,od..It has now been found that, instead of metal halides, metalloid halides can also advantageously be used. The oil is reacted with hydrofluoric acid to which small amounts of a metalloid halide have been added. After about 2 hours the cleaning process is finished and the oils can be distilled. Since the hydrofluoric acid already boils at 20 °, most of the hydrofluoric acid can easily be driven off and used immediately for a new refining process. If a gaseous metalloid halide is added, this is also recovered in the same operation. The rest of the hydrofluoric acid forms double compounds with the unsaturated constituents of the oil and the polymerisation products, which only disintegrate again when the oils are distilled. In order to recover this part of the hydrofluoric acid, it can prove to be advantageous to distill the oil with halium fluoride. The free hydrofluoric acid is then bound quantitatively, and the result is neutral oils that no longer need to be washed. Example I Petroleum is treated with 4 ° ("hydrofluoric acid and 2 ° /, boron fluoride for 4 hours at room temperature. The bromine number of the oil drops from 2.2 to oi Treated at room temperature for 2 hours with d. % Hydrofluoric acid and 100% PF. The bromine number drops from 2.2 to o, or

Das Verfahren kann zweckmäßig auch bei höheren Temperaturen oder erhöhtem Druck oder gleichzeitig unter beiden Bedingungen ausgeführt werden, wobei -der Druck stets in Abhängigkeit von der Temperatur ist und sich aus dem Partialdruck des Öles und dem der Flußsäure zusammensetzt.The process can also expediently take place at higher or higher temperatures Print or at the same time under both conditions, with -the print is always dependent on the temperature and is derived from the partial pressure of the oil and that of hydrofluoric acid.
