Description

Verfahren und Vorrichtung zur alleinigen oder zusätzlichen Temperaturregelung von Hochdrucksynthesereaktoren durch kaltgaseinspeisung Die ereindung betrifft ein Verfahren und eine Vorrichtung zur alleinigen oder zusätzlichen Temperaturregelung von Hochdruck synthesereaktoren durch Kaltgaseinspeisung. Method and device for sole or additional temperature control of high pressure synthesis reactors through cold gas injection The invention concerns a Method and device for sole or additional temperature control of high pressure synthesis reactors through cold gas feed.

Bei solchen Reaktoren ist es wichtig, die Katalysatortemperatur dem durch den Jeweiligen Reaktionsgrad gegebenem Optimu anzu passen und den Druckverlust klein zu halten.In such reactors it is important to know the catalyst temperature to adjust the given Optimu by the respective degree of reaction and the pressure loss to keep it small.

Zum Regeln der Temperatur sind verschiedene Verfahren z Vorrichtungen bekannt geworden. Eines davon besteht in der Zuführung von kaltem, noch nicht reagiertem Frischgas zwischen die cinzelnen Kontaktschlisse eines Ofens. Hiebei ist es zur Brreichung einer optimalen Reaktionsführung von großer Bedeutung. das aus der vorhergehenden Schicht austretende eiße Gas mit dem kalten Synthesegas so gut zu mischen. daß das Gemsisch über den ganzen Reakrorquerschnitt einheitliche Temperatur aufweist; bisher wurde dies dadurch bewirk@. daß man das gesamte Gemisch durch eine enge Blende Pührte, wobei es intensiv gemischt wrde ("Quench-gas converter" oder "Blendenofen"). Der Druckverlust solcher Vorrichtungen ist hoch, Sieht man dagegen Durchmischung durch eine praktisch verlustlose Mischstrecke vor, so geht baulich teurer Rochdruckraum des Reaktors verloren, Die Ereindung bezweckt eine Vermeidung der genannten Nach teile mit möglichst einfachen Mitteln, Uberraschenderweise wurde gefunden, daß die gleiche Wirkung ohne Druckverlust auP kleinstem Raum durch Mischdüsen erreicht werden kann, die das kalte Synthesegas mit entsprechender Geschwindigkeit senkrecht zur Strömungsrichtung in den heißen Gasstrom einführen. Da das kalte Synthesegas gegenüber dem heißen Gas nach der rontaktschicht mit dem ursprünglichen Druck zur Verfügung steht bedingt das Verfahren keinen zusätzlichen Druckverlust. Ein ganz besonderer Vorteil der Erfindung liegt in ihrem geringen Platzbedarf.Various methods are available for regulating the temperature known. One of these is the addition of cold, unreacted material Fresh gas between the individual contact closures of a furnace. Here it is for Achieving an optimal reaction procedure is of great importance. that from the previous one Layer escaping hot gas to mix so well with the cold synthesis gas. that this Gemsisch has a uniform temperature over the entire reactor cross-section; until now was this caused @. that he the entire mixture through one narrow aperture, whereby it is intensively mixed ("quench gas converter" or "Aperture oven"). The pressure loss of such devices is high, if you look at it Mixing through a practically lossless mixing section is how structurally works expensive pressure chamber of the reactor lost, the purpose of the installation is to avoid it the after-mentioned parts with the simplest possible means, surprisingly became found that the same effect without pressure loss in the smallest of spaces thanks to mixing nozzles can be achieved that the cold synthesis gas with appropriate speed Introduce into the hot gas stream perpendicular to the direction of flow. Because the cold synthesis gas compared to the hot gas after the contact layer with the original pressure The process does not require any additional pressure loss. A very A particular advantage of the invention is its small footprint.

Die Erfindung betrifft also ein Verfahren zur alleinigen oder zusätzlichen Temperaturregelung on Hochdruck synthese reaktoren, vorzugsweise für die Ammoniaksynthese, durch Zumischen von kaltem Frischgas, gekennzeichnet dadurch, daß das kalte Frischgas annähernd senkrcht zur Strömungsrichtung des heißen Gases mit einer Geschwindigkeit von wenigstens 0,5 m/sec., vorzugsweise aber von 2 m/sec., eingeblasen wird.The invention thus relates to a method for the sole or additional Temperature control of high pressure synthesis reactors, preferably for ammonia synthesis, by admixing cold fresh gas, characterized in that the cold fresh gas approximately perpendicular to the direction of flow of the hot gas with a velocity at least 0.5 m / sec., but preferably 2 m / sec., is blown in.
