Abstract

In sepn. of oil and plastics, the oil is combined with a solvent in which the plastic is insol. A variant claimed provides for solvent recovery in the system. USE/ADVANTAGE - This is an economical sepn. method that enables both plastic and oil, from the used plastic packaging of oil, to be supplied for recycling. The soln. of the oil in the solvent allows complete cleaning of the plastic including removal of such matter as paper labels. The oil can easily be separated from the solvent by fractionating. The large amts. of this type of used packaging have hitherto been treated as "special" refuse and burned or dumped.

Description

Die Erfindung betrifft ein Verfahren zum Separieren von Kunststoff und Öl aus gebrauchtem Kunststoff Ölverpackungen als vorbereitenden Schritt zum Recycling.The invention relates to a method for separating Plastic and oil from used plastic Oil packaging as a preparatory step for recycling.

Derartige Ölverpackungen fallen in großer Menge an, und müssen bis heute als Sondermüll entsorgt werden. Als solcher werden sie gesondert verbrannt oder deponiert.Such oil packaging is produced in large quantities, and to date have to be disposed of as special waste. As they are burned or deposited separately.

Der Erfindung liegt die Aufgabe zugrunde, ein wirtschaftlich durchführbares Verfahren zu schaffen, das es gestattet, sowohl den Kunststoff als auch das Öl einem Recycling zuzuführen.The invention is based on the object to create economically feasible process that it allowed both the plastic and the oil Recycle.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Patentanspruches 1 angegebene Maßnahme gelöst. Die weitere Ausbildung des Erfindungsgegenstandes geht aus den Unteransprüchen hervor.This object is achieved by the in the license plate of claim 1 specified measure solved. The further development of the subject of the invention starts the subclaims.

Die mit der Erfindung erzielten Vorteile bestehen im wesentlichen darin, daß durch die Lösung des Öles im Lösungsmittel eine vollständige Reinigung des Kunststoffes, auch von anderen Verunreinigungen wie Papieretiketten u. a., erreicht wird. Weiterhin läßt sich das Öl durch Fraktionierung in einfacher Weise von dem Lösungsmittel trennen. Die dadurch erhaltenen Fraktionen sind in dieser Form in herkömmlichen weiteren Aufbereitungsverfahren verarbeitbar. Durch eine geschlossene Kreislaufführung des Lösungsmittels werden Emissionen vermieden und die Wirtschaftlichkeit ist gegeben.The advantages achieved by the invention are essential in that by the solution of the oil in Solvent a complete cleaning of the plastic, also from other contaminants such as paper labels u. a. is achieved. Furthermore, the oil can pass through Fractionation in a simple manner from the solvent separate. The fractions thus obtained are in this Form in conventional further preparation processes processable. Through a closed circuit of the Emissions are avoided and the solvent Economy is given.

Für dieses Separationsverfahren eröffnet sich eine Reihe von Anwendungsmöglichkeiten vor allem auf den Gebieten der Entsorgung und dem Altstoffrecycling.A number opens up for this separation process of applications, especially in the fields of Disposal and recycling of waste.
