Description
Verfahren zur fraktionierten Destillation, insbesondere von Kohlenwasserstoffen. Eine der Hauptschwierigkeiten bei der fraktionierten Destillation von Flüssigkeitsgemischen, z. B. eines Kohlenwasserstoffgemisches, wie es das rohe Erdöl darstellt, besteht bekanntlich darin, eine wirklich vollständige und reine Scheidung in die den einzelnen Temperaturgrenzen entsprechenden Destillationsprodukte zu erzielen. Erschwert wird die Erreichung dieses Zieles einerseits dadurch, daß dabei in jedem Stadium nicht nur diejenigen Gemischbestandteile übergehen, deren Siedepunkt der bei dem betreffenden Stadium erreichten Temperatur gleich ist oder sie übertrifft, sondern daß jeweils auch noch nicht siedende, schwerer flüchtige Substanzen mitgerissen werden, und daß andererseits in jedem Stadium keineswegs alle Gemischbestandteile, deren Siedetemperatur erreicht oder übertroffen ist, übergehen. Die Folge ist; daß, wenn man auf wirklich reine Scheidung Wert' legt, man gezwungen ist, den Destillationsvorgang und die Temperatursteigerung möglichst langsam vor sich gehen zu lassen. Dadurch wird aber naturgemäß die Wirtschaftlichkeit nachteilig beeinflußt.Process for fractional distillation, especially of hydrocarbons. One of the main difficulties in fractional distillation of liquid mixtures, z. B. a hydrocarbon mixture, as it is the crude petroleum, consists known to be a really complete and pure divorce in the individual To achieve temperature limits corresponding distillation products. Is made more difficult the achievement of this goal on the one hand by not doing so in every stage only those components of the mixture pass over whose boiling point is the same as in the case in question Stage reached temperature is the same or exceeds it, but that in each case also not yet boiling, less volatile substances are entrained, and that on the other hand in every stage by no means all components of the mixture, their boiling point is reached or exceeded. The result is; that when you get on really pure divorce values', one is forced to the distillation process and the Let the temperature increase go as slowly as possible. But this will naturally adversely affects the economy.
Die Erfindung zeigt nun aber einen Weg, auf dem trotz größter Destillationsgeschwindigkeit eine vollständige und reine Trennung zu erreichen ist. Die auf diesem Wege gewonnenen Destillationsprodukte zeichnen sich überdies auch durch weitgehende Freiheit von fremden Verunreinigungen aus. Das neue Verfahren besteht darin, daß den zu destillierenden Gemischen ein Zusatz von Seife im Betrage von etwa 1/4 bis i1/2 Prozent zugesetzt wird. Diese Seife löst sich, wenn z. B. rohes Erdöl destilliert werden soll, in diesem bei etwa ioo bis iio ° C. Ausgedehnte Versuche haben bewiesen, daß durch dieses einfache Mittel scharf abgegrenzte Destülationsstufen erreicht, ein Mitreißen von noch flüssigen Bestandteilen und Schmutzstoffen verhindert und eine vollständige der jeweiligen Temperatur entsprechende Verflüchtigung erzielt wird. Ist -die Destillation vollkommen durchgeführt, so verbleibt die Seife in den Rückständen und löst sich, wenn auf diese neues Öl aufgegeben wird, in letzterem, sobald beim nächsten Destillationsvorgang die Temperatur. wieder die genügende Höhe erreicht hat. Dieselbe Menge Seife ist also solange wiederverwendbar, als die Menge der Rückstände nicht eine unzulässige Größe erreicht hat.However, the invention now shows a way in which a complete and pure separation can be achieved despite the greatest distillation speed. The distillation products obtained in this way are also characterized by their extensive freedom from foreign impurities. The new process consists in adding soap in the amount of about 1/4 to 1/2 percent to the mixtures to be distilled. This soap dissolves when z. B. crude oil is to be distilled, in this at about 100 to 100 ° C. Extensive experiments have shown that this simple means can be used to achieve sharply defined distillation stages, prevent entrainment of still liquid components and contaminants and complete volatilization corresponding to the respective temperature is achieved. Is - the distillation carried out completely, the soap remains in the residues and dissolves when placed in this new oil, in the latter as soon as the next distillation process the temperature. has reached the sufficient height again. The same amount of soap can therefore be reused as long as the amount of residue has not reached an impermissible level.
