Claims (3)

  1. Verfahren zur Regeneration gebrauchter Schmieröle, dadurch gekennzeichnet, dass es nacheinander die folgenden Behandlungsschritte umfasst:
    a) Homogenisieren der gesammelten Öle und Eliminierung derselben, wenn sie einen der folgenden Tests nicht bestehen:
    Chlorflammentest (Chlortest);
    Test auf Anwesenheit von Heizöl durch Fleckentest (Tropfentest);
    Test auf Anwesenheit von Fettsäure mit Soda (Fett-Test);
    b) Vorerhitzen, wobei die zu regenerierenden Öle auf eine Temperatur zwischen 140 und 160 °C gebracht werden;
    c) Hinzufügen von Natriumhydroxid in wässriger Lösung in einer Menge von 1 bis 3% reine Base, bezogen auf die Masse des Schmieröls;
    d) Entwässern und Entfernen leichter Kohlenwasserstoffe durch Entspannung (Flashverdampfen);
    e) Entfernen und Rückgewinnen von Dieselöl (Strippen);
    f) Entfernen von Verunreinigungen durch fraktionierende Destillation im Vakuum, die eine Auftrennung einerseits in rohe Schmieröle und andererseits in einen Rückstand, in dem alle Verunreinigungen konzentriert sind, gewährleistet.
  2. Verfahren zur Regeneration gebrauchter Schmieröle gemäß Anspruch 1, dadurch gekennzeichnet, dass die Kolonne bei der Destillation im Vakuum mit einem Kolonnenboden-Absaugverdampfer zusammenarbeitet.
  3. Vorrichtung zur Regeneration gebrauchter Öle, umfassend:
    einen Vorratsbehälter (2) für gebrauchte Öle;
    Einrichtungen zum Mischen und Homogenisieren der anfangs in dem Vorratsbehälter (2) enthaltenen Öle;
    Einrichtungen (3) zum Vorerhitzen, die die aus dem Vorratsbehälter (2) entnommenen gebrauchten Öle auf eine Temperatur zwischen 140 °C und 160 °C bringen;
    Einrichtungen (4) zur Aufbewahrung von reinem Natriumhydroxid;
    Einrichtungen (5) zum Zumischen von Natriumhydroxid in einem vorbestimmten Anteil zwischen 1 und 3 Massen-% zu den vorerhitzten gebrauchten Ölen;
    eine Einheit (6) zum Entfernen von Wasser und leichten Kohlenwasserstoffen durch Entspannung (Flashverdampfen) aus den gebrauchten Ölen, die auf eine erhöhte Temperatur gebracht und mit reinem Natriumhydroxid versetzt wurden;
    eine Einheit (8) zum Entfernen von Dieselöl (Strippen); und
    Einrichtungen (10, 14) zum Entfernen von Verunreinigungen, die eine Einheit (10) zur Destillation im Vakuum umfassen.
