Description

Verbesserung in der Ausführung des Edeleanuverfahrens. Bei der Behandlung von Kohlenwasserstoffen mit verflüssigter schwefliger Säure nach dem sogenannten Edeleanuv erfahren erleidet man sehr geringe Verluste an schwefliger Säure, teils durch gelegentliche kleine Undichtigkeiten an der geschlossenen Apparatur, teils dadurch, daß die mit der schwefligen Säure behandelten Öle noch Bruchteile von Prozenten derselben enthalten, wenn sie die Apparatur verlassen.Improvement in the execution of the Edeleanu process. In the treatment of hydrocarbons with liquefied sulphurous acid according to the so-called Edeleanuv experienced very little losses of sulphurous acid, partly due to occasional small leaks in the closed apparatus, in part in that the oils treated with the sulphurous acid are still fractions of a percent the same when they leave the apparatus.

Um diese kleinen Verluste wieder zu ergänzen, führt man dem Prozeß immer wieder die entsprechenden Mengen an reiner flüssiger, schwefliger Säure zu. Auf nachstehend beschriebene Weise gelingt es indessen, die Einführung frischer verflüssigter Säure in den Kreislauf des Verfahrens zu vermeiden und die unvermeidlichen Verluste unmittelbar aus den Verbrennungsgasen der Schwefel- bzw. Schwefelkiesöfen zu ergänzen.The process is carried out to make up for these small losses again and again the corresponding amounts of pure liquid, sulphurous acid. In the following way, however, it is possible to make the introduction fresher Avoid liquefied acid in the process cycle and the inevitable Losses directly from the combustion gases of the sulfur and sulfur gravel stoves to complete.

Man läßt die Öle, welche der Behandlung mit schwefliger Säure unterzogen werden sollen, über einen mit Raschigringen oder einem sonstigen geeigneten Füll- und Verteilungsmaterial gefüllten oder mit passenden Einbauten versehenenTurm rieseln, an dessen unterem Ende die Verbrennungsgase eines Schwefel- oder Schwefelkiesofens eintreten und der Flüssigkeit entgegenströmen. Sowohl Kerosene wie Gasöl- und Schmieröldestillate nehmen mit Leichtigkeit % Prozent und mehr schweflige Säure aus den Verbrennungsgasen auf, und zwar um so mehr, je niedriger die Temperatur ist. Da indessen die Verluste an schwefliger Säure bei guter Führung des Edeleanuprozesses kaum % Prozent, meistens sehr erheblich weniger betragen, so kann man selbst da, wo man mit tropischen Temperaturen zu rechnen hat, sicher sein, daß diejenige Menge schwefliger Säure absorbiert wird, welche nachher im Laufe der Verarbeitung wieder verlorengeht.The oils are left which have undergone the treatment with sulphurous acid should be, via a with Raschig rings or another suitable filling tower filled with distribution material or fitted with suitable internals trickle, at its lower end the combustion gases from a sulfur or pebble furnace enter and flow counter to the liquid. Kerosene as well as gas oil and lubricating oil distillates easily remove% percent and more sulphurous acid from the combustion gases the lower the temperature, the more so. Meanwhile the losses of sulphurous acid with good management of the noble anup process hardly% percent, mostly be very considerably less, so you can even there, where you have tropical temperatures has to reckon, be sure that the amount of sulphurous acid is absorbed which is then lost again in the course of processing.

Die Erfindung bewirkt also, daß man bei Inbetriebsetzung einer Anlage nur einmal dasjenige Quantum von flüssiger schwefliger Säure anzuschaffen braucht, welches zum Arbeiten nötig ist, während alle eintretenden Betriebsverluste in der vorstehend geschilderten Weise gutgemacht werden. Die Quelle, aus der man sich die S02 Gase beschafft, berührt die Erfindung und deren Ausführung nicht, für die kennzeichnend ist, daß man die Absorptionsfähigkeit der Erdölkohlenwasserstoffe gegenüber S02 Gasen benutzt, um dadurch die Kosten und Verluste zu vermeiden, die mit deren Verflüssigung unbedingt einhergehen. Je reiner die Gase sind, die man zur Absorption verwendet, desto einfacher gestaltet sich die Durchführung des neuen Verfahrens, das in der Benutzung von Verbrennungsgasen des Schwefels in Sauerstoff gipfelt.The invention thus has the effect that when a system is put into operation only needs to purchase that quantity of liquid sulphurous acid once, which is necessary to work, while all operating losses occurring in the be made good in the manner described above. The source from which you can get the S02 gases procured does not affect the invention and its implementation, for which it is characteristic is that the absorption capacity of petroleum hydrocarbons against SO2 Gases are used, thereby avoiding the costs and losses associated with liquefying them necessarily go hand in hand. The purer the gases that are used for absorption, the easier it is to carry out the new procedure, which is included in the Use of combustion gases of sulfur culminates in oxygen.
