KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es hat sich bei der Gewinnung von Cyan nach dem Bueb'schen Verfahren oder ähn- _, liehen Methoden, welche neuerdings mit der Leuchtgaserzeugung meistens Hand in Hand geht, als zweckmäßig erwiesen, das Cyan bei hoher Temperatur aus dem Gase abzuscheiden, weil dadurch die Ausbeute nicht unerheblich erhöht wird. Da aber die nachträgliche Ausscheidung der noch in dem Gase befindlichen Ammoniakmengen bei hoher Temperatur nicht durchführbar ist, so wird durch die in vorgenannter Weise erfolgende Cyangewinnung eine nochmalige Kühlung des Gases zwischen dem Cyanabscheider und dem Ammoniakwäscher erforderlich gemacht, wie bereits in der das vorgenannte Bueb'sehe Verfahren betreffenden Patentschrift 122280, letztem Absatz, vorgeschlagen ist.In the extraction of cyan according to the Bueb's process or similar _, borrowed methods, which lately with the Light gas generation mostly goes hand in hand, which has proven to be useful, with the cyan to be separated from the gases at a high temperature, because this means that the yield is not insignificant is increased. But there is the subsequent elimination of those still in the gas Ammonia is not feasible at high temperature, so is by the in the aforementioned Wise cyan recovery takes place a further cooling of the gas between the cyano separator and the ammonia scrubber made necessary, as already in the above-mentioned Bueb'sehe process Patent 122280, last paragraph, is proposed.
Diese Nachkühlung in rationeller Weise mit der Abscheidung des in dem Gase befindlichen Naphtalins zu verbinden, ist der Zweck des vorliegenden Verfahrens.This after-cooling in a rational manner with the deposition of what is in the gases Joining naphthalene is the purpose of the present process.
Hiernach wird das Naphtalin nicht durch (-■ einen vor dem Cyanabscheider angeordnetenAccording to this, the naphthalene is not (- ■ arranged in front of the cyan separator
Ölwäscher abgeschieden, sondern erst nach der Cyanabscheidung entfernt, und zwar durch einen zwischen dem Cyanabscheider und dem Ammoniakwäscher eingeschalteten, gleichzeitig als Nachkühler und Naphtalinwäscher wirkenden Kolonnenapparat, der beispielsweise aus einem zweiräumigen Behälter bestehen kann, in welchem immer je eine Schicht wagerechter Waschhorden mit einer darunter liegenden Gruppe wagerechter Kühlrohre abwechseln, wenn nicht letztere gleichzeitig als Waschflächen dienen. Die aus mit Benzol gesättigtem Anthracenöl bestehende Waschflüssigkeit wird aus einem Hochbehälter in geeigneter Weise in den Kolonnenapparat derartig eingeführt, daß sie die in letzterem befindlichen Wrascbhorden und Kühlrohre berieselt. Nachdem die Waschflüssigkeit genügend mit Naphtalin gesättigt ist, wird sie aus dem Kolonnenapparat abgeführt und kann hiernach zweckmäßig in den hinter der Teervorlage, also vor dem Cyanwäscher, befindlichen Vorkühler geleitet werden, um die Kühlfläche desselben zu bespülen und dadurch von Naphtalinabscheidungen freizuhalten.Separated oil scrubber, but only removed after the cyan separation, namely by a column apparatus connected between the cyan separator and the ammonia scrubber, which simultaneously acts as an aftercooler and naphthalene scrubber, which can consist, for example, of a two-room container in which there is always a layer of horizontal washing trays with an underneath Alternate lying group of horizontal cooling tubes, if the latter do not serve as washing areas at the same time. Comprising saturated with benzene anthracene washing liquid is introduced from a high-level tank in a suitable way into the column apparatus, such that the r ascbhorden in the latter located W and sprayed cooling tubes. After the washing liquid is sufficiently saturated with naphthalene, it is discharged from the column apparatus and can then conveniently be passed into the precooler located behind the tar reservoir, i.e. in front of the cyan washer, in order to flush the cooling surface of the same and thereby keep it free of naphthalene deposits.
Durch das beschriebene Verfahren werden folgende Vorteile erzielt.The following advantages are achieved by the method described.
Zunächst wird durch die Berieselung der in dem Naphtalinwäscher befindlichen Kühlflächen ein stetes Reinhalten der letzteren und dadurch eine wesentliche Erhöhung der Kühlwirkung bedingt. Der gleiche Erfolg wird aber durch die Überführung der mit Naphtalin gesättigten Waschflüssigkeit in den Vorkühler auch in diesem erzielt, da das gesättigte Anthracenöl, welches zwar kein Naphtalin mehr absorbieren kann, doch noch zur Beseitigung der sich sonst auf den Kühlflächen des Vorkühlers absetzenden flüssigen oder festen Naphtalinabscheidungen verwendbar ist, welche die Kühlwirkung stets mehr oder wehiger beeinträchtigen. ίFirst, the cooling surfaces located in the naphthalene washer are sprinkled a constant cleanliness of the latter and thereby a significant increase in the cooling effect conditional. The same success is achieved with the transfer of the naphthalene saturated washing liquid in the pre-cooler is also achieved in this, since the saturated anthracene oil, which can no longer absorb naphthalene, but still to eliminate the otherwise on the cooling surfaces of the pre-cooler settling liquid or solid naphthalene deposits can be used, which always impair the cooling effect more or more. ί
An Stelle eines zweiräumigen Nachkühlärs und Naphlalinwäschers können natürlich auchInstead of a two-room aftercooler and naphlalin washers can of course also
mehrere voneinander getrennte Kolonnenapparate verwendet werden, die in der beschriebenen Weise zusammenwirken.several separate column apparatuses are used, which are described in the Cooperate in a way.
