Description

Verfahren zur kontinuierlichen VacÜumdestillation von Rohölen unter Verwendung eines Röhrenerhitzers und einer Verdampferkolonne Die Erfindung bezieht sich auf ein Verfahren zur kontinuierlichen V acuumdestillation von Rohölen unter Verwendung eines Röhrenerhitzers und einer * Verdampferkolonne.Process for the continuous vacuum distillation of crude oils under Use of a tubular heater and an evaporator column The invention relates refers to a process for the continuous vacuum distillation of crude oils Use of a tube heater and an * evaporator column.

Gemäß Erfindung wird das aus dem Röhrenerhitzer kommende .Gemisch von flüssigem und dampfförmigem 01 in fein verteiltem Zustand, z. B. mittels einer Verteilerspinne, in den Rückstandssumpf der Verdampferkolonne eingeleitet, tun eine gute Ausrüfirung des Rückstandes zu bewirken.According to the invention, the mixture coming from the tube heater is of liquid and vaporous 01 in a finely divided state, e.g. B. by means of a Distributor spiders, introduced into the residue sump of the evaporation column, do one to effect good equipment of the residue.

Man hat bereits beim Destillieren von Mineralölen leichte Mineralöldämpfe (Benzindämpfe) in die Destillationsrückstände .eingeleitet.Even when distilling mineral oils, one has light mineral oil vapors (Petrol vapors) in the distillation residues .introduced.

Hierbei wurden aber die zur Einleitung in das Rohöl benötigten leichten' Kohlenwasserstoffe zunächst in einem besonderen Kanal verdampft und alsdann dem zu behandelnden Rohöl, das in einem Kessel erwärmt wurde, zugeführt, und es wurden diese leichten Mineralöldämpfe nach dem Kondensieren wieder im Kreislauf von neuem verwendet.Here, however, the light ' Hydrocarbons first evaporated in a special channel and then the crude oil to be treated, which was heated in a kettle, was supplied, and it was these light mineral oil vapors are recirculated again after condensation used.

Die hierbei immer wieder erforderliche Anwärmung der leichten Mineralöldämpfe und der hierzu erforderliche Kessel fallen gemäß Erfindung fort.The repeatedly required heating of the light mineral oil vapors and the boiler required for this are omitted according to the invention.

Auch hat man bereits das Rohöl in einer Destillationsblase auf etwa 40o° erhitzt und die hierbei entstehenden flüchtigen Kohlenwasserstoffe über vier hintereinandergeschaltete Dephleagnatoren geleitet, wobei die im Schlußkühler noch nicht kondensierten Gase vorgewärmt und im Kreislauf durch die Destillationsblase geschickt wurden. Gegenüber diesem bekannten Verfahren wird gemäß Erfindung das der fraktionierten Destillation zu unterwerfende Rohöl im Röhren-, erhitzer auf eine Temperatur von 3oo bis ¢0o° C'gebracht, bei der alle im- Rohöl enthaltenen leichten Kohlenwasserstoffe bereits in Dampfform übergegangen sind, so daß sie mit den noch in flüssiger Form sich befinden-' den schweren Kohlen-vasserstoffen in den Rückstandssumpf des Verdampfers geleitet werden können.You also have the crude oil in a still to about 40o ° heated and the resulting volatile hydrocarbons over four series-connected Dephleagnatoren passed, with those in the final cooler still non-condensed gases are preheated and circulated through the still were sent. Compared to this known method, according to the invention crude oil to be subjected to fractional distillation in the tube heater brought a temperature of 300 to ¢ 0o ° C ', at which all contained in the crude oil light hydrocarbons have already gone into vapor form, so that they with which are still in liquid form - the heavy hydrocarbons in the residue sump of the evaporator can be passed.

In weiterer Ausbildung der Erfindung kann mari gleiglizeitig überhitzten Wasserdampf in den Rückstandssumpf einleiten, um das Ausrühren zu begünstigen. .In a further embodiment of the invention, mari can overheat at the same time Introduce steam into the residue sump to encourage stirring. .

In- der Zeichnung ist ein Ausführungsbei-.- spiel -einer zur _ Ausübung des Verfahrens dienenden Vorrichtung dargestellt, und zwar ist i eine Pumpe, z ein Röhrenerhitzer und 3 ein Verdampfer. 4 ist die Zuleitung des Dampfes und 5 die Ableitung zu den Kondensationskolonnen und zur Vacuumpumpe. 6 ist die Verteilerspinne.In the drawing is an exemplary embodiment -.- game -one for exercise the device serving the method shown, namely i is a pump, z a Tube heater and 3 an evaporator. 4 is the inlet of the steam and 5 is the discharge to the condensation columns and to the vacuum pump. 6 is the distributor spider.
