Description

Reinigung von Rohölabfallsäure. Es ist bekannt, daß man die Abfallsäure der Rohölreinigung durch Kneten mit Benzin oder Petroleum in Säure und Abfallharz trennen kann (Patentschrift 233517). Dieses Verfahren hat jedoch den Nachteil, daß die durch das Kneten von größeren Mengen Säureteer bzw. Rohölabfallsäure mit Benzin oder Petroleum geschaffene Berührung beider Komponenten nicht so innig ist, daß eine technisch vollkommene Entmischung des Säureteers in Säure und Harz hervorgerufen wird.Purification of waste crude oil. It is known that you can waste acid the cleaning of crude oil by kneading with gasoline or petroleum in acid and waste resin can separate (patent 233517). However, this method has the disadvantage that by kneading large amounts of acid tar or crude oil waste acid with gasoline or petroleum created contact of the two components is not so intimate that technically complete separation of the acid tar into acid and resin will.

Dieses Ziel wird aber erreicht, wenn man die Rohölabfallsäure evtl. nach dem Verdünnen mit Wasser mit Schwerbenzin oder Schwerbenzol oder Tetralin in einer Zentrifuge rührt und ausschleudert. Dadurch wird die für einen Angriff des Entmischungsmittels nötige Berührungsfläche geschaffen und dadurch einesteils eine Säure, andernteils ein Harz von solcher Reinheit gewonnen. wie es nach dem bekannten Verfahren nicht möglich ist.However, this goal is achieved if the crude oil waste acid is removed. after diluting with water with heavy gasoline or heavy benzene or tetralin in a centrifuge stirs and centrifuges. This prevents the Separation means created necessary contact surface and thereby on the one hand a Acid, on the other hand a resin of such purity obtained. as it is according to the known Procedure is not possible.

Um die für das vorliegende Verfahren nötige Flüssigkeit des Säureteers bzw. der Reinigungssäure zu erreichen, ist es nötig, die Säure entweder schwach zu erwärmen oder aber ihr solche Mengen `Vasser zuzusetzen, wie zur Erreichung der gewünschten Flüssigkeit nötig ist.The acid tar liquid required for the present process or to achieve the cleaning acid, it is necessary to make the acid either weak to warm it up or to add such quantities of water to it as to achieve the required liquid.

Des weiteren hat sich gezeigt, daß nicht jede Petroleumfraktion die gleiche Fähigkeit der Entmischung des Säureteers bzw. der Rohölreinigungssäure hat. Das von etwa 12o bis 18o° siedende Schwerbenzin ist dem Leichtbenzin und dem Leuchtpetroleum unbedingt überlegen, wobei gegenüber dem Leichtbenzin die geringere Flüchtigkeit und die höheren Siedegrenzen hervorzuheben sind. Das Petroleum hat den Nachteil, daß es sich nicht vollständig vom Säureharz trennen läßt, sondern ihm eine schmierige Konsistenz verleiht, die der weiteren Verarbeitung des Harzes hinderlich ist.Furthermore it has been shown that not every petroleum fraction the has the same ability to separate the acid tar or the crude oil cleaning acid. The heavy gasoline, which boils from about 12o to 18o °, is the same as light gasoline and kerosene absolutely superior, with the lower volatility compared to light gasoline and the higher boiling limits are to be emphasized. The disadvantage of kerosene is that it cannot be completely separated from the acid resin, but rather a greasy one Lends consistency that hinders the further processing of the resin.

Mit Schwerbenzin wird aber ein nach dem Erkalten brüchiges, dabei umverbranntes Harz gewonnen, das sich leicht mahlen oder stampfen und mit alkalischen Mitteln weiterverarbeiten läßt.With heavy gasoline, however, it becomes brittle after cooling recovered burned resin, which can easily be ground or mashed and with alkaline Can further process funds.

Die gleichen Vorzüge bietet eine Behandlung der Reinigungssäure mit Schwerbenzol oder Tetralin.Treatment with cleaning acid offers the same advantages Heavy benzene or tetralin.
