Abstract

The invention relates to a process for removing PCBs and other dissolved halogenated organic pollutants from waste oil using a column packed with adsorber resin or with adsorber resin in a cascade-like batch process.

Description

Die Erfindung betrifft ein Verfahren zur Entfernung von PCB und anderen gelösten halogenierten organischen Schadstoffen aus Altölen unter Verwendung einer mit Adsorberharz gefüllten Ko­ lonne oder mit Adsorberharz in einem kaskadenförmigen Batch- Verfahren.The invention relates to a method for removing PCB and other dissolved halogenated organic pollutants Used oils using a Ko filled with adsorber resin lonne or with adsorber resin in a cascade-shaped batch Method.

In vielen Industrienationen, bevorzugt in hoch industrialisier­ ten Ländern der Erde, fallen Millionen Tonnen Altöle an, allein in der Bundesrepublik Deutschland im Jahr ca. 500 000 Tonnen, die zum Teil mit toxischen Stoffen stark belastet sind.In many industrialized nations, preferably in highly industrialized ones In countries around the world, millions of tons of waste oils are produced, alone in the Federal Republic of Germany about 500,000 tons a year, some of which are heavily contaminated with toxic substances.

1. Industriealtöle fallen in relativ großen Chargen und da­ mit homogener Form an, wie z.B. Hydraulik-, Turbinen- oder Transformatorenöle.1. Industrial waste oils fall in relatively large batches and there with a homogeneous shape, e.g. Hydraulic, turbine or Transformer oils.

2. Motorenaltöle stellen die größte und homogenste Gruppe von Altölen dar.2. Used motor oils are the largest and most homogeneous group of Waste oils.

Die größte Gruppe von Altölen bilden die Öle, die infolge ihres Einsatzes mit vielen Fremdstoffen, zum Teil mit persistenten toxischen Chemikalien verunreinigt sind.The largest group of waste oils are the oils that result from their Use with many foreign substances, some with persistent toxic chemicals are contaminated.

Derartige Altöle werden üblicherweise entweder einer mit hohen Kosten verbundenen Verbrennung unterworfen oder auf kostspieli­ ge Weise destilliert. Die beiden oben genannten Entsorgungs­ verfahren stellen für Mensch und Umwelt ein großes Problem dar und sind nach heutiger Sicht unbefriedigend. Such waste oils are usually either high Subject to incidental combustion or at cost distilled in a manner. The above two disposal Processes are a major problem for people and the environment and are unsatisfactory from today's perspective.  

Es ist bekannt, daß Adsorberharze auf der Basis von Polystyrol- Copolymeren ohne funktionellen Endgruppen mit einer bestimmten Porosität in der Lage sind, organische Stoffe aus Wasser mit unterschiedlichem Wirkungsgrad zu adsorbieren. Das beladene Harz kann mit Lösungsmitteln, z.B. Aceton oder Methanol rege­ neriert und dann wiederverwendet werden.It is known that adsorber resins based on polystyrene Copolymers without functional end groups with a certain Porosity are able to use organic substances from water to adsorb different efficiency. The loaded Resin can be mixed with solvents e.g. Acetone or methanol brisk be generated and then reused.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren bereitzustellen, das die umweltbelastenden Nachteile vorbekann­ ter Arbeitsweisen nicht aufweist und trotzdem in der Lage ist, Altöle entsprechend aufzubereiten, und bei dem mit einem vor­ gegebenen Adsorberharzvolumen eine hochbelastete Altölmenge gereinigt werden kann.The invention is therefore based on the object of a method to provide that the environmentally harmful disadvantages is not able to work and is still able to Prepare used oils accordingly, and with one before given adsorber resin volume a highly contaminated amount of waste oil can be cleaned.

Zur Lösung dieser Aufgabe dient zum einen das erfindungsgemäße Verfahren, das dadurch gekennzeichnet ist, daß eine teilweise mit dem Adsorberharz gefüllte Kolonne (siehe Anlage 1) mit dem zu reinigenden Altöl so lange beaufschlagt wird, bis die Adsorbtionskapazität des Harzes erreicht ist.To solve this problem, the process according to the invention is used on the one hand, which is characterized in that a column partially filled with the adsorber resin (see Appendix 1 ) is charged with the waste oil to be cleaned until the adsorption capacity of the resin is reached.

Zum anderen das erfindungsmäßige mehrstufige Verfahren, das dadurch gekennzeichnet ist, daß das Altöl in teilweise mit Adsorberharz gefüllten, kaskadenförmig angeordneten Behäl­ tern (Gefäß) (siehe Anlage 2) eine bestimmte Zeit gerührt wird (ca. 10-20 Minuten) und daß anschließend das jetzt bereits teilweise gereinigte Altöl in den nachfolgenden Behältern weiter gereinigt wird. Die kaskadenförmige Anordnung der Rühr­ behälter wird vom Altöl so lange fortgesetzt durchlaufen, bis das Altöl von halogenierten organischen Schadstoffen ge­ reinigt ist.On the other hand, the inventive multi-stage process, the is characterized in that the waste oil in part with Adsorber resin filled, cascaded containers tern (vessel) (see Appendix 2) is stirred for a certain time (about 10-20 minutes) and that afterwards that is already partially cleaned used oil in the following containers is further cleaned. The cascade arrangement of the stirrer the used oil will continue to run through the container until the waste oil from halogenated organic pollutants is cleaned.

Bevorzugte Ausführungsformen des erfindungsgemäßen Verfah­ rens sind in den Patentansprüchen 2-11 näher beschrieben.Preferred embodiments of the method according to the invention rens are described in more detail in claims 2-11.
