Description
Verfahren zur Herstellung von hochwertigen technischen Ölen aus minderwertigen Abfallfetten und Ölen. Bekannt ist die Herstellung heller Öle aus dunklen Abfallfetten durch Destillation mit oder ohne überhitzten Wasserdampf. Die hierfür üblichen Verfahren haben jedoch den großen Nachteil, daß sich durch die Destillation unverseifbare und übelriechende Bestandteile von dunkler Farbe - Kohlenwasserstoffe - bilden, die die Qualität des Produktes ungünstig beeinflussen. Der diesen Produkten weiter anhaftende Nachteil des Nachdunkelns hat seinen Grund entweder in dem Umstand, daß das Destillat in Gegenwart des Kondensats mit der Luft in Berührung kommt, oder daß das Kondenswasser nach erfolgter Abkühlung bei gewöhnlicher Temperatur durch Absetzenlassen vom Fett getrennt wird. Ein weiterer Übelstand dieser Verfahren ist das Auftreten lästiger und schwer zu trennender Emulsionen, welche das destillierte Produkt mit dem Kondenswasser bildet, wenn es in Gegenwart von überhitztem Wasserdampf destilliert wird.Process for the production of high quality technical oils from inferior ones Waste fats and oils. The production of light-colored oils from dark waste fats is known by distillation with or without superheated steam. The usual procedures for this however, have the major disadvantage that the distillation results in unsaponifiable and form malodorous components of dark color - hydrocarbons - which adversely affect the quality of the product. Of these products further The inherent disadvantage of darkening has its reason either in the fact that the distillate comes into contact with the air in the presence of the condensate, or that the condensation water through after cooling at normal temperature Settling is separated from the fat. Another drawback of these procedures is the appearance of troublesome and difficult-to-separate emulsions which distilled it Product forms with the condensation water when in the presence of superheated water vapor is distilled.
Gegenstand der vorliegenden Erfindung ist nun ein Zerfahren, welches unter Vermeidung der vorstehend beschriebenen Mängel in einem einzigen Arbeitsgange sowohl die verseifbaren Bestandteile von den unverseifbaren trennt als auch die schlecht riechenden Stoffe abscheidet und außerdem noch durch sofortige Trennung der unverseifbaren und schlecht riechenden Bestandteile und des kondensierten Wassers von dem Produkt dieses, also den voll verseifbaren Teil, am Dunkelwerden bzw. Nachdunkeln verhindert, ihm also eine helle Färbung sichert. Der im selben Arbeitsgang vor sich gehende Dampfprozeß dient auch noch zur Beseitigung von entweder schon im Rohstoff, also vor der Destillation vorhandenen, oder sich nachher während der Destillation durch Abspaltung bildenden schlecht riechenden Stoffen.The present invention is now a disintegration, which while avoiding the defects described above in a single operation separates both the saponifiable constituents from the unsaponifiable and the separates bad smelling substances and also by immediate separation the unsaponifiable and bad-smelling components and the condensed water of the product of this, i.e. the fully saponifiable part, of darkening or darkening prevents it, so it ensures a light color. The one in front of you in the same operation going steam process also serves to remove either already in the raw material, that is present before the distillation, or afterwards during the distillation by splitting off bad smelling substances.
Zur Darstellung des Arbeitsvorganges diene folgendes Ausführungsbeispiel.The following exemplary embodiment is used to illustrate the working process.
In einem Kessel werden etwa rooo kg Abfallöl, z. B. Tallöl, in Gegenwart von überhitztem Wasserdampf auf etwa 29o° C erwärmt und die übergehenden Dämpfe in einem zweiten emaillierten Kessel aufgefangen. Im Innern dieses zweiten Kessels herrscht eine Temperatur von etwa 2oo° C. In beiden Kesseln ist ein starkes Vakuum vorhanden. Der zweite Kessel ist an einen Kataraktkondensator angeschlossen, der «-feder in Verbindung mit einer Luftpumpe steht.In a boiler about rooo kg of waste oil, z. B. tall oil, in the present warmed by superheated steam to about 29o ° C and the passing vapors collected in a second enamelled kettle. Inside this second cauldron the temperature is around 2oo ° C. There is a strong vacuum in both tanks available. The second boiler is connected to a cataract capacitor, the «-Spring is in connection with an air pump.
Die nicht v erseifbaren, dunklen, und die schlecht riechenden Stoffe werden mit den Wasserdämpfen durch den Kataraktkondensator fortgerissen und kondensieren mit den Wasserdämpfen auf dem Wege durch den Kataraktkondensator. Auf diesem Wege «erden diese Körper, welche brennbare Kohlenwasserstoffe darstellen, vorn Wasser getrennt.The unsaponifiable, dark and bad-smelling substances are carried away with the water vapors through the cataract capacitor and condense with the water vapors on the way through the cataract condenser. On this way «These bodies, which are flammable hydrocarbons, earth from the water separated.
In dem zweiten Kessel sammelt sich das helle, nicht riechende, fast voll verseifbare Öl, welches, ohne mit der Luft in Berührung zu kommen, in einen dritten emaillierten, evakuierten Kessel abdestilliert wird. Dieser dritte Kessel ist gleichzeitig als Kühler ausgebildet. Beim Abdestillieren hat dieser Kessel ein stärkeres Vakuum als der von ihm zu entleerende Kessel. In diesem dritten Kessel, dem Kühler, wird das Öl abgekühlt, ehe es mit der Luft in Berührung kommt, und dann in einen Vorratstank gelassen.In the second cauldron, the light, non-smelling, almost collects fully saponifiable oil, which, without coming into contact with the air, in a third enamelled, evacuated Kettle is distilled. This third boiler is also designed as a cooler. When distilling off this has Boiler a stronger vacuum than the boiler to be emptied. In this third Kettle, the cooler, the oil is cooled before it comes into contact with the air, and then left in a storage tank.
