Description

Anlage zur Gewinnung von Nebenerzeugnissen aus Destillationsgasen Bei der Gewinnung der Nebenerzeugnisse aus Destillationsgas wurde zur Beförderung des Gases bisher immer ein einziges, allerdings oft in mehrere Stufen unterteiltes Gebläse verwendet, durch das das Gas in den meisten Fällen vor dem Eintritt in die Ammoniakwäscher angesaugt wurde (vgl.Gluud, Handbuch der Kokerei 1928, Bd. 2, S. 49/5o). Die einmalige Saugung des Gases an der bezeichneten Stelle bringt einen starken Überdruck in den Ammoniak- und Benzolwäschern hervor; dadurch, daß .die Verdichtung an einer einzigen Stelle stattfindet, muß vor den Ammoniakwäschern, .die mit verhältnismäßig niedriger Temperatur laufen, ein besonderer Schlußkühler zur Aufnahme der Kompressionswärme angeordnet werden.Plant for the extraction of by-products from distillation gases In the extraction of the by-products from distillation gas was used for transportation of the gas has always been a single one, albeit often divided into several stages Blower is used, through which the gas in most cases before entering the Ammonia scrubber was sucked in (see Glud, Handbuch der Kokerei 1928, Vol. 2, p. 49 / 5o). The one-time suction of the gas at the designated point brings you strong overpressure in the ammonia and benzene washers; in that .the Compression takes place at a single point, must be before the ammonia scrubbers, .which run at a relatively low temperature, a special final cooler to absorb the compression heat.

Gemäß der Erfindung sollen zur Beförderung des Gases zwei Gebläse vorgesehen sein: in das eine soll das Gas geführt werden, nachdem es die Teerabscheider verlassen hat und bevor es in die Ammoniakfabrik eintritt. Der zweite Sauger befördert das Gas, unmittelbar nachdem es durch Waschen mit Teeröl von Benzol befreit ist. Durch diese Anordnung werden eine Reihe bedeutender Vorteile erreicht. Zunächst ist der Gasüberdruck in den Ammoniak- und Benzolwäschern bedeutend geringer. Da die heute in allgemeinen Gebrauch gekommenen Turbosauger im Gase enthaltene Teer- und Ölteilchen ausschleudern und in besonderen unterhalb der Laufräder angebrachten Teerabläufen sammeln, so macht sich, falls das Gas nach Verlassen der Benzolwäscher hinter der zweiten Saugstufe zur Befreiung des Gases von Schwefel durch Reinigerkästen geschickt wird, in diesen keine so starke Verschmutzung durch Teerteilchen bemerkbar. Es kann sich daher erübrigen, an dieser Stelle besondere Ölreiniger, die ein 'beträchtliches Druckgefälle aufnehmen, anzubringen. Der sogenannte Schlußkühler vor der Ammoniakfabrik kann kleiner dimensioniert oder auch ganz fortgelassen werden. Die Endtemperatur des weitergeleiteten, beispielsweise zur Beheizung der Öfen bestimmten Gases wird durch die Kompressionswärme der zweiten Saugstufe erhöht. Dies ist mit Rücksicht auf die Gefahr von Teer-und COlabscheidungen in den Verteilungsleitungen, insbesondere in den zu den Starkgasbrennern der Koksöfen führenden Düsen, ebenfalls von Vorteil.According to the invention, two fans are to be used for conveying the gas be provided: the gas is to be fed into one after it has passed the tar separator and before it enters the ammonia factory. The second sucker promotes the gas immediately after benzene is removed from it by washing with tar oil. A number of important advantages are achieved by this arrangement. First the gas overpressure in the ammonia and benzene washers is significantly lower. There the turbo vacuums that are now in common use in the gases and throw out oil particles and attached in special below the impellers Collect tar drains, so if the gas leaves the benzene scrubber behind the second suction stage to remove sulfur from the gas by means of cleaning boxes is sent, in these no so strong pollution by tar particles is noticeable. It may therefore be unnecessary to use special oil cleaners at this point, which have a 'considerable Record pressure gradient, apply. The so-called final cooler in front of the ammonia factory can be made smaller or omitted entirely. The final temperature of the forwarded gas, for example intended for heating the ovens increased by the heat of compression of the second suction stage. This is with consideration at the risk of tar and CO deposits in the distribution lines, in particular in the nozzles leading to the high-gas burners of the coke ovens, also an advantage.

Eine besonders einfache Leitungsführung kann trotz der Verwendung zweier getrennter Stufen des Gebläses dann erreicht werden, wenn sich die Gebläse ebenso wie die Vorrichtungen zum Umpumpen der Waschflüssigkeiten (Wasser für Ammoniak, Teeröl für Benzol) in einem Raum befinden, der unterhalb der Waschtürme liegt. In .diesem Falle können wie bisher die beiden Stufen des Gebläses zu einer Maschineneinheit zusammengef.aßt werden, beispielsweise indem beide Saugstufen durch auf der gleichen Welle laufende Flügel gebildet «erden.A particularly simple line routing can despite the use two separate stages of the fan can then be achieved when the fan as well as the devices for pumping the washing liquids (water for ammonia, Tar oil for benzene) in a room below the washing towers. In .In this case, as before, the two stages of the fan can become one machine unit be summarized, for example by having both suction levels through on the same Wave moving wings formed «ground.
