Description

Im Patent 928 726 wurde ein Verfahren zum Abtrennen von Paraffin aus paraffinhaltigen Kohlenwasserstoffölen beschrieben. Nach diesem Verfahren wird das paraffinhaltige Gemisch mit oder ohne Zusatz von Lösungsmittel in einem Gasraum fein verteilt und die dabei gebildete körnige Masse in Lösungsmittel angemaischt und verrührt, abgetrennt und. aufgearbeitet. .In patent 928 726 a method for separating paraffin from paraffin-containing hydrocarbon oils described. After this procedure, the paraffin-containing mixture with or without the addition of solvent in a gas space finely divided and the resulting granular mass mashed in solvent and stirred, separated and. worked up. .

Das Versprühen des gegebenenfalls Lösungsmittel enthaltenden paraffinhaltigen Ölgemisches kann nun vorteilhaft direkt in einen Sprühregen von Lösungsmittel erfolgen. Dadurch wird einmal die Berührung der körnigen Paraffin-Öl-Masse mit dem Lösungsmittel intensiviert; zum anderen erleichtert eine solche Arbeitsweise die Gewinnung von Paraffinen von ganz bestimmtem Schmelzpunkt, insbesondere auch die Fraktionierung in Hart- und Weichparaffine.The spraying of the paraffin-containing, optionally solvent-containing Oil mixture can now advantageously be done directly in a spray of solvent. This means that the granular paraffin-oil mass comes into contact with the solvent stepped up; on the other hand, such a way of working makes it easier to obtain Paraffins with a very specific melting point, especially fractionation in hard and soft paraffins.

DieMenge desLösurngsmittels, in das hinein das Paraffin-Öl-Gemisrh versprüht wird, kann hierbei ebenso groß oder kleiner sein als das Lösungsmittelvolumen, das zum Anmäischen vorgesehen war; seineTemperatur wird unterhalb .des Schmelzpunktes des gewünschten Paraffins gehalten.The amount of solvent into which the paraffin-oil mixture is sprayed, can be as large or smaller than the solvent volume, that was intended for mucking; its temperature is below the melting point of the desired paraffin held.

Der Brei, bestehend aus Lösungsmittel und der versprühten Paraffin-Öl-Masse, fällt in den entsprechend .eingerichteten, beispielsweise konischen, unteren Teil des Sprühturmes und wird von dort zur Filtriervorrichtdng gefördert. Die Anordnung der Sprühdüsen für Lösungsmittel kann oberhalb oder unterhalb der Sprühdüsen für Paraffinöl oder auch in gleicher Höhe wie diese erfolgen.The pulp, consisting of solvent and the sprayed paraffin-oil mass, falls in the appropriately arranged, for example conical, lower part of the spray tower and is conveyed from there to the filter device. The order the spray nozzles for solvent can be above or below the spray nozzles for Paraffin oil or in the same amount as this.
