Die Erfindung bezweckt, das Paraffin aus seinen Rohölen oder Lösungen zum Zwecke der Reinigung einfacher und zweckmäfsiger abzuscheiden, als dies bis jetzt der Fall ist.The invention aims to use the paraffin from its crude oils or solutions for the purpose the cleaning easier and more expedient to separate than has been the case up to now.
Das gegenwärtig übliche Verfahren besteht darin, dafs das Rohparaffin in einer so concentrirten Lösung zum Erstarren gebracht wird, dafs die erstarrte Masse fest genug ist, um sich in Prefstücher packen und in hydraulischen Pressen unter hohem Druck auspressen zu lassen. Diese nothwendige Concentration der Lösung gestattet aber die Anwendung einer nur geringen Menge Benzin, ungefähr 15 bis 20 pCt., welche geringe Menge nicht alles schwere OeI, welches dem Rohparaffin anhaftet, auf einmal aufnehmen kann, weshalb die Operation öfter wiederholt werden mufs. Dies ist umständlich, wie überhaupt dieses ganze Verfahren bekanntlich kostspielig und zeitraubend ist, und viele Prefstücher, viel Benzin, grofse, kühl zu haltende Räume mit ausgedehnten Wasserflächen'u. s. w. erfordert.The current practice consists in concentrating the raw paraffin in such a way Solution is made to solidify that the solidified mass is firm enough to stand Pack in prefabricated cloths and press out in hydraulic presses under high pressure permit. This necessary concentration of the solution, however, permits the use of a only a small amount of gasoline, about 15 to 20 pct., what a small amount not everything heavy oil, which adheres to the raw paraffin, can absorb at once, which is why the operation must be repeated more often. This is cumbersome, like all of this Procedure is known to be costly and time-consuming, and a lot of cloth, a lot of gasoline, large rooms, to be kept cool, with extensive areas of water. s. w. requires.
Diese Uebelstände werden durch das neue Verfahren beseitigt.These deficiencies are eliminated by the new procedure.
Es wird nämlich das Rohparaffin in einer so großen Menge Benzin gelöst, dafs dieselbe im Stande ist, das dem Paraffin anhaftende schwere OeI auf einmal aufzunehmen. Wird diese dünnere Lösung in geschlossenen Gefäfsen einer möglichst niedrigen Temperatur ausgesetzt, etwa —10 bis 150C, so krystallisirt das reine Paraffin vollständig aus, aber nicht in so festem Zustande, dafs es sich in Prefstücher packen und pressen liefse, und daran scheiterte eben bisher die einmalige Anwendung einer grofsen Menge Benzin, weil die Trennung des Paraffinbreies von der Flüssig-" keit mit Hülfe der üblichen Einrichtungen nicht erfolgen konnte.The raw paraffin is dissolved in such a large quantity of gasoline that it is able to take up the heavy oil adhering to the paraffin at once. If this thinner solution exposed in closed Gefäfsen the lowest possible temperature, about -10 to 15 0 C, the pure paraffin crystallizes completely, but not in such solid state, that it is in Prefstücher grab and squeeze liefse, and failed because just hitherto the single use of a large amount of gasoline, because the separation of the paraffin paste from the liquid could not be carried out with the aid of the usual devices.
Dies gelingt jedoch mittelst einer besonderen Vorrichtung, welche darin besteht, dafs bei Filterpressen zwischen je einer Filterplatte α eine sogenannte Kühltasche (Kammer) b angebracht wird, durchweiche eine Lauge von —10 bis 150 Kälte circulirt. Die Kühltaschen sind durch Gelenke oder biegsame Röhren mit den Zu- und Ableitungsrohren für die Kälteflüssigkeit verbunden, um die Filterkammern öffnen und die Kuchen ablösen zu können. Wird die dünne Masse durch eine so eingerichtete Filterpresse geprefst, so läuft nur das Benzin mit dem in ihm gelösten schweren OeI ab, während man das Paraffin in Form von Kuchen rein erhält.However, this is achieved by means of a special device which is, that at each filter press between a filter plate α a so-called cooling bag (chamber) b is attached, by a soft liquor from -10 to 15 0 refrigerant circulates. The cooling bags are connected by joints or flexible tubes to the inlet and outlet pipes for the cold liquid, so that the filter chambers can be opened and the cakes can be removed. If the thin mass is pressed through a filter press set up in this way, only the gasoline with the heavy oil dissolved in it runs off, while the paraffin is obtained pure in the form of cake.
' In einer gewöhnlichen Filterpresse mit üblichen Kühlungsschlangen innerhalb der Filterplatten läfst sich die Operation nicht ausführen, weil bei dieser Einrichtung in erster Linie die Platten des Filters selbst, an denen die abgeprefste Flüssigkeit abläuft, abgekühlt werden, und zwar stärker als das Prefsgut, dessen Temperatur im Gegentheil durch den Druck etwas erhöht wird. Infolge dessen tritt der Uebelstand auf, dafs sich auskrystallisirtes Paraffin in der grofsen Menge Benzin wieder löst, aber an den Platten des Filters wieder ausscheidet und den Gang der Filtration hemmt. Die Kühltaschen dagegen kühlen in erster Linie das Prefsgut ab;'' The operation cannot be carried out in a normal filter press with normal cooling coils within the filter plates, because with this device primarily the plates of the filter itself, on which the squeezed Liquid runs off, are cooled, and more than the Prefsgut, its temperature on the contrary, it is somewhat increased by the pressure. As a result of this the evil arises point out that crystallized paraffin dissolves again in the great amount of gasoline, but separates again on the plates of the filter and inhibits the process of filtration. The cool bags on the other hand, it is primarily the material to be prepared that cools down;
das Paraffin setzt sich auf beiden Seiten dieser Taschen an, und die Flüssigkeit läuft an den Filterplatten ohne weitere Ausscheidung ab.the paraffin settles on both sides of these pockets and the liquid runs on the Filter plates off without further separation.
Bei der Abscheidung des Rohparaffins aus den Paraffinölen tritt in jeder bisher angewendeten Art Presse der Nachtheil auf, dafs das Prefsgut sich erwärmt, infolge dessen auskrystallisirtes Paraffin sich wieder löst und mit den Oelen abfliefst, weshalb die Anwendung des neuen Verfahrens auch zur Abscheidung von Rohparaffin ebenso vortheilhaft ist, wie zu seiner Reinigung.When separating the raw paraffin from the paraffin oils occurs in each previously used The disadvantage of a kind of press is that the material to be prepared heats up, as a result of which it crystallizes out Paraffin dissolves again and flows off with the oils, which is why the application of the new process for the separation of raw paraffin is just as beneficial as to his purification.
Die Kühltaschen lassen sich bei allen Arten Pressen anwenden.The cool bags can be used with all types of presses.
