Description

Verfahren und Vorrichtung zur Herstellung von Acetylen durch partielle Oxydation gasförmiger oder verdampfter Kohlenwasserstoffe Es ist bekannt, Acetylen durch partielle Oxydation gasförmiger oder verdampfter Kohlenwasserstoffe mit Sauerstoff herzustellen, indem die Reaktionsteilnehmer gemeinsam oder vorzugsweise getrennt vorgewärmt, das Gemisch dem Reaktionsraum zugeführt, in einer Flamme umgesetzt und die Reaktionsgase in einem Zeitpunkt rasch abgekühlt werden, in dem die maximale Menge Acetylen auf Grund des Reaktionsverlaufes im Gasgemisch vorhanden ist. Die Abschreckung erfolgt zweckmäßig durch Einspritzen von Wasser in das Gasgemisch nach Verlassen des Reaktionsraumes. Process and apparatus for the production of acetylene by partial Oxidation of gaseous or vaporized hydrocarbons It is known, acetylene by partial oxidation of gaseous or vaporized hydrocarbons with oxygen prepare by bringing the reactants together or, preferably, separately preheated, the mixture fed to the reaction chamber, reacted in a flame and the reaction gases are rapidly cooled at a point in time when the maximum Amount of acetylene is present in the gas mixture due to the course of the reaction. the Quenching is expediently carried out by injecting water into the gas mixture Leaving the reaction space.

Es hat sich nun gezeigt, daß das in einer Ebene senkrecht zur Strömungsrichtung eingespritzte Wasser für das Gas einen erheblichen Strömungswiderstand darstellt, so daß ein Teil des Gases seitlich zwischen der Austrittsöffnung des Reaktionsraumes und der Einspritzebene austritt. Dieser Teil des Gases wird daher nicht rechtzeitig abgekühlt, und die Folge ist, daß sich das in ihm enthaltene Acetylen teilweise unter Rußbildung zersetzt. Die Ausbeute an Acetylen wird dadurch merklich beeinträchtigt, während sich der störende Rußgehalt des Gases erhöht. It has now been shown that this occurs in a plane perpendicular to the direction of flow injected water represents a considerable flow resistance for the gas, so that part of the gas laterally between the outlet opening of the reaction chamber and the injection level exits. This part of the gas is therefore not made on time cooled, and the result is that the acetylene contained in it partially decomposed with soot formation. The acetylene yield is noticeably impaired by this, while the troublesome soot content of the gas increases.

Man hat versucht, diesen Mißstand durch eine Anordnung gemäß Abb. 1 zu beheben. Das vorgewärmte Kohlenwasserstoff-Sauerstoff-Gemisch wird von oben her durch den mit parallelen Kanälen versehenen BrennerblockA in den durch einen wassergekühlten Mantel C begrenzten Reaktionsraum B geleitet, wo unter Flammenbildung die Reaktion vor sich geht. Dicht unterhalb der Austrittsöffnung des Reaktionsraumes ist ein Kranz von Düsen D angeordnet, aus denen feinverteiltes Wasser quer zum Gasstrom eingespritzt wird. Bei dieser Arbeitsweise ist eine sehr genaue Justierung der Düsen erforderlich. Sind die Düsen zu hoch angeordnet, kann dadurch Wasser in den Reaktionsraum geraten, daß die der Düse gegenüberliegende Innenwand vom Strahl getroffen wird, oder es wird ein Teil des Wassers nicht ausgenutzt, weil es gegen die zwischen der - dejustiert gedachten - Düse und dem Gasstrom befindliche Wand des Reaktionsraumes prallt. Bei zu tiefer Anordnung der Düse ist kein wirksamer seitlicher Abschluß mit Wasser gewährleistet. Aber auch bei genauester Einstellung der Düsen läßt es sich mit dieser Anordnung nicht vermeiden, daß ein Teil des Reaktionsgases in noch heißem Zustand aus dem Reaktionsraum entweicht und somit das in diesem Teil enthaltene Acetylen weitgehend zersetzt wird. Attempts have been made to remedy this deficiency by means of an arrangement as shown in Fig. 1 fix. The preheated hydrocarbon-oxygen mixture is from above through the burner block A, which is provided with parallel channels, into the through a water-cooled jacket C directed limited reaction space B, where flame formation the reaction is going on. Just below the outlet opening of the reaction chamber a ring of nozzles D is arranged, from which finely divided water transversely to the gas flow is injected. This mode of operation requires very precise adjustment of the nozzles necessary. If the nozzles are too high, water can get into the reaction chamber advised that the inner wall opposite the nozzle is hit by the jet, or a part of the water is not used because it is against the between the - imagined misaligned - nozzle and the gas flow located wall of the reaction space bounces. If the nozzle is positioned too deeply, there is no effective lateral closure guaranteed with water. But even with the most precise setting of the nozzles, it works With this arrangement do not avoid that part of the reaction gas in still hot state escapes from the reaction chamber and thus the contained in this part Acetylene is largely decomposed.

Es wurde nun gefunden, daß diese Schwierigkeiten dadurch behoben werden können, daß man das Wasser am Ende des Reaktionsraumes parallel zu einer an dem Reaktionsraum senkrecht zum Gas strom angeordneten ebenen Wand einführt, wobei der Abstand zwischen dem Wasser und der Wand so klein gehalten wird, daß das in diesem Zwischenraum befindliche Gas in Richtung des Wassers mitgerissen wird. Auf diese Weise wird mit Sicherheit verhindert, daß ein Teil des Gases seitlich austritt. It has now been found that this overcomes these difficulties can be that the water at the end of the reaction chamber parallel to a introduces a flat wall arranged perpendicular to the gas flow in the reaction chamber, being the distance between the water and the wall is kept so small that the Gas located in this gap is entrained in the direction of the water. In this way it is prevented with certainty that part of the gas sideways exit.

Abb. 2 zeigt schematisch eine zweckmäßige Vorrichtung für die Durchführung dieses Verfahrens. Das Gas strömt wie in der bekannten Vorrichtung gemäß Abb. 1 von oben her durch die Kanäle des Brennerblocks A in den Reaktionsraum B. An dem unteren Ende des Mantels C des Reaktionsraumes B ist eine ebene ringförmige Platte E befestigt, zu der parallel das Abschreckwasser aus einem Ring von Düsen D eingespritzt wird. Fig. 2 shows schematically an expedient device for the implementation this procedure. The gas flows as in the known device according to Fig. 1 from above through the channels of the burner block A into the reaction chamber B. At the lower end of the jacket C of the reaction space B is a flat annular plate E attached, to which the quenching water is injected from a ring of nozzles D in parallel will.

Es hat sich gezeigt, daß sich ein wirksamer seitlicher Abschluß auch dann erzielen läßt, wenn das Wasser nicht genau parallel zu der Wand geführt wird, sondern unter einem kleinen Winkel auf die Wand auftrifft. Eine geringfügige Dejustierung der zum Einspritzen benutzten Düsen, die leicht auftreten kann, ist also bei dieser Anordnung unerheblich. In Abb. 3 ist diese Abänderung dargestellt. It has been shown that an effective side closure is also possible can be achieved if the water is not guided exactly parallel to the wall, but hits the wall at a small angle. A slight misalignment of the nozzles used for injection, which can easily occur, is so with this one Arrangement irrelevant. This modification is shown in Fig. 3.

Als günstigste Dimensionierung der Wand hat sich eine radiale Ausdehnung zwischen 80 und 200 mm, vorzugsweise 100 und 150 mm, von der inneren Öffnung nach außen gerechnet, erwiesen. Diese Abmessung gewährleistet einerseits einen hinreichenden Abschluß für das Gas, andererseits sind die Einspritzdüsen nicht in zu großer Entfernung vom Gasstrom angeordnet. A radial expansion has proven to be the most favorable dimensioning of the wall between 80 and 200 mm, preferably 100 and 150 mm, from the inner opening towards outside calculated, proven. This dimension ensures on the one hand a sufficient Closure for the gas, on the other hand the injection nozzles are not too far away arranged by the gas flow.

Beispiel In einem Vorwärmer werden 800 Nm3/h Methan auf eine Temperatur von 6400 C und in einem zweiten Vorwärmer 450 Nm3/h Sauerstoff ebenfalls auf eine Temperatur von 6400 C erhitzt. Die heißen Gase werden einer Mischvorrichtung zugeführt. Nach vollständiger Durchmischung tritt das Gemisch in der in Abb. 1 dargestellten Vorrichtung durch die parallelen Kanäle des Brennerblocks A in den Reaktionsraum B ein, wo das Methan mit dem Sauerstoff unter Flammenbildung reagiert. Die Realftionsgasewerden in der Weise abgekühlt, daß an der Austrittsöffnung des Reaktionsraumes durch einen Kranz von Düsen D Wasser in feinverteilter Form eingespritzt wird. Man erhält ein Gasgemisch, das 8,3 Volumprozent Acetylen enthält und pro m3 3,0 g Ruß mit sich führt. Example In a preheater, 800 Nm3 / h methane are heated to one temperature of 6400 C and in a second preheater 450 Nm3 / h oxygen also to one Heated to a temperature of 6400 C. The hot gases are fed to a mixing device. After complete mixing, the mixture appears as shown in Fig. 1 Device through the parallel channels of burner block A into the reaction space B a, where the methane reacts with the oxygen to form flames. The Realftionsgas will cooled in such a way that at the outlet opening of the reaction chamber by a Wreath of nozzles D water is injected in finely divided form. One receives a Gas mixture that contains 8.3 percent by volume acetylene and 3.0 g of soot per m3 leads.

Man arbeitet unter gleichen Bedingungen in der in Abb. 2 dargestellten Vorrichtung, in der der Reaktionsraum B an der Austrittsöffnung mit einer ringförmigen Platte E mit einer radialen Ausdehnung von 125 mm versehen ist. Man erhält ein Gasgemisch, das 8,5 Volumprozent Acetylen enthält und pro m8 1,77 g Ruß mit sich führt. One works under the same conditions in the one shown in Fig. 2 Device in which the reaction space B at the outlet opening with an annular Plate E is provided with a radial extension of 125 mm. A gas mixture is obtained which contains 8.5 percent by volume of acetylene and carries 1.77 g of soot per m8 with it.
