Description

Verfahren zur Herstellung von hochwertigem Paraffin Es ist bekannt, aus paraffinhaltigem Öl, aus dem -durch Abkühlen das Paraffin abgeschieden ist, durch Zentrifugieren ölhaltiges Rohparaffin zu gewinnen. Es ist ferner bekannt, ölhaltiges Paraffin unter Erwärmen auf etwa io° unter dem Erstarrungspunkt des Paraffins zu schleudern und auf diese Weise höherwertiges Paraffin zu erzielen.Process for the production of high quality paraffin It is known from paraffin-containing oil, from which the paraffin is separated by cooling, to obtain oil-containing raw paraffin by centrifugation. It is also known Oil-containing paraffin with heating to about 10 ° below the solidification point of the paraffin to spin and in this way to achieve higher quality paraffin.

Es wurde nun gefunden, daß man in sehr guter Ausbeute und in ganz kurzer Zeit hochwertiges Paraffin herstellen kann, wenn man Rohparaffin, das in geeigneter Weise, z. B. mit Hilfe von Zentrifugen, Drehfiltern, Filterpressen usw., aus Ölen abgeschieden -,vorden ist, unter gleichzeitigem allmählichen Erwärmen bis zum Erstarrungspunkt des zu gewinnenden Reinparaffins, z. B. in einer Zentrifuge, schleudert. Durch dieses allmähliche Erwärmen wird gegenüber den bekannten Verfahren eine neue, besondere technische Wirkung erzielt. Je wärmer das 01 beim Abschleudern ist, desto mehr Paraffin nimmt es gelöst mit fort. Wenn man beim Schleudern schnell, wie bei dem bekannten Verfahren, aufwärmt, wird die Ausbeute an reinem Paraffin geringer als bei allmählichem Aufwärmen. Bei niedrigeren Wärmegraden nimmt das Öl weniger Paraffin mit fort. Die Ausbeute an reinem Paraffin wird durch das allmähliche Erwärmen beim Schleudern bedeutend erhöht.It has now been found that in very good yield and in whole high-quality paraffin can be produced in a short time if you use raw paraffin that is in suitable way, e.g. B. with the help of centrifuges, rotary filters, filter presses, etc., deposited from oils -, vorden is, while at the same time gradually heating up to the freezing point of the pure paraffin to be obtained, e.g. B. in a centrifuge, flings. As a result of this gradual heating, compared to the known processes achieved a new, special technical effect. The warmer the 01 when throwing it off is, the more paraffin dissolved it takes away with it. If you spin fast, as in the known method, warming up, the yield is pure paraffin less than with gradual warm-up. At lower degrees of warmth, the oil decreases less paraffin with go. The yield of pure paraffin is due to the gradual Heating during spinning increased significantly.

Das beim Erwärmen zuerst ablaufende Öl hat einen Erstarrungspunkt von etwa 3o° und enthält etwa 2o°/, Paraffin; es kann mit dein Ausgangsöl zusammen wieder verarbeitet werden. Das später ablaufende Öl, das bei richtiger Durchführung nur in geringer Menge anfällt, hat einen Erstarrungspunkt von etwa 45 bis 5o° und enthält etwa 70°/0 Paraffin; -es kann nochmals auf die gleiche Weise geschleudert werden. Durch das Erwärmen bis 5o°, bis zum Erstarrungspunkt des Paraffins, erreicht man, daß als Rückstand in der Zentrifuge besonders hochweniges Paraffin verbleibt, das nach Behandeln mit Entfärbungs- oder Raffinationsmitteln einem guten Handelsparaffin entspricht. Das vorliegende Verfahren gestattet gleichzeitig, Paraffin zu fraktionieren.The oil that drains off first when it is heated has a solidification point of about 30 ° and contains about 20% paraffin; it can be related to your starting oil can be processed again. The later draining oil, if done correctly is only obtained in small quantities, has a freezing point of about 45 to 50 ° and contains about 70% paraffin; -It can be spun again in the same way will. Reached by heating up to 50 °, until the paraffin solidifies that the residue in the centrifuge is particularly low in paraffin, after treatment with decolorizing or refining agents, a good commercial paraffin is equivalent to. The present process allows paraffin to be fractionated at the same time.

Das Abschleudern des Öls verläuft besonders glatt, wenn man das Rohparaffin vorher zuerst schmilzt und dann wieder erstarren läßt. Wesentlich für die Durchführung der Behandlung ist es, die Hauptmenge des dem Rohparaffin anhaftenden Öles bei niedriger Temperatur abzuschleudern.The spinning off of the oil is particularly smooth if you use the raw paraffin first melts and then solidifies again. Essential for the implementation the treatment is to reduce the bulk of the oil adhering to the slack wax at a lower level Throwing off temperature.

Beispiel i ioo Teile Rohparaffin aus Braunkohlenhvdrierun.gspr:odukten mit einem Gehalt an Paraffin von 61,4°i" werden in einer Siebzentrifuge, die einen Durchmesser von 1,20 m hat und goo Umdrehungen in der Minute macht, unter ganz allmählichem Erwärmen geschleudert. Wenn nur noch wenig Öl abläuft, wird die Zentrifuge noch etwas stärker erwärmt, am zweckmäßigsten durch Einblasen von Dampf. Nach 85 Minuten hat das Ablauföl einen Stockpunkt an q.6°. In der Zentrifuge, verbleiben 3g: Teile 96°J°.igen Paraffins.Example 100 parts of raw paraffin from brown coal mining products with a paraffin content of 61.4 ° i "are in a sieve centrifuge, the one Has a diameter of 1.20 m and makes goo revolutions per minute, under very gradual Heating centrifuged. If only a little oil is draining, the centrifuge will still work a little bit stronger heated, most expediently by blowing in steam. After 85 minutes the drain oil has a pour point of q.6 °. Remain in the centrifuge 3g: parts of 96 ° C.igen paraffin.

Beispiel e Zoo Teile Rohparaffin aus Braunkohlenhydrierungsprodukten mit einem Gehalt an Paraffin von 61,d.°/0 werden, geschmolzen, nach dem Erkalten zerkleinert und dann in der in Beispiel i beschriebenen Weise behandelt. Nach 45 Minuten hat das Ablauföl einen Stockpunkt von 50°. Es hinterbleiben 44 Teile 98,2°J°igen Paraffins.Example e zoo parts slack wax from brown carbohydrate products with a paraffin content of 61, i.e. ° / 0, are melted after cooling crushed and then treated in the manner described in example i. After 45 Minutes, the drain oil has a pour point of 50 °. There remain 44 parts 98.2 degrees Paraffins.

Beispiel 3 In eine Zentrifuge von 2 m Durchmesser, die 350 Umdrehungen in der Minute macht, Nverden 5oo kg Rollparaffin mit einem Beingehalt von 7o°/° eingebracht. Die Aufwärmung erfolgt -durch Wasser, das während des Laufens der Zentrifuge eingebracht -wird und dessen Temperatur allmählich gesteigert wird, bis .der Erstarrungspunkt des mit dem Wasser abgehenden Paraffins 5o° beträgt. Es werden 225 kg 9%'J°iges Paraffin erhalten.Example 3 In a centrifuge with a diameter of 2 m, which rotates 350 revolutions per minute, 500 kg of rolling paraffin with a leg content of 70 ° / ° are introduced. The heating is done by water that is introduced while the centrifuge is running and the temperature of which is gradually increased until the solidification point of the paraffin leaving with the water is 50 °. 225 kg of 9% paraffin are obtained.
