Patentiert im Deutschen Reiche vom 7. August 1912 ab.Patented in the German Empire on August 7, 1912.
Bei der Abscheidung von Ammoniak aus unter Druck stehenden Gasgemischen, z. B. solchen, wie sie bei der synthetischen Herstellung von Ammoniak aus seinen Elementen gewonnen werden, mittels flüssiger Absorptionsmittel tritt, besonders wenn es sich um große Gasmengen handelt, der Übelstand auf, daß bei Verwendung der- üblichen Absorptionsapparate (Türme, Wäschapparate usw.) ίο sehr umfangreiche Vorrichtungen nötig sind, die mit Rücksicht auf die erforderliche Druckbeständigkeit nur mit großen Kosten oder bei sehr hohen Drucken überhaupt kaum mehr zu beschaffen sind.When separating ammonia from pressurized gas mixtures, e.g. B. such as those used in the synthetic production of ammonia from its elements Be obtained by means of liquid absorbent occurs, especially if it is large amounts of gas are involved, the disadvantage that when using the usual absorption apparatus (Towers, washing machines, etc.) ίο very extensive devices are required, those with regard to the required pressure resistance only at great cost or at very high pressures can hardly be obtained at all.
ki5 Es hat sich nun gezeigt, daß man solche ammoniakhaltige, unter Druck stehende Gasgemische, die man als schwer kondensierbar bezeichnen kann, vorteilhaft in der Weise mit flüssigen Absorptionsmitteln, insbesondere Wasser, behandelt, daß man die Gase gemeinsam mit den Absorptionsmitteln im Gleichstrom durch Rohre hindurchführt. Die Absorption von Ammoniak, speziell auch unter Druck, ist bisher noch nicht mittels von außen eingeführter, flüssiger Absorptionsmittel im Gleichstrom bewirkt worden. Man hat vielmehr bisher lediglich bei einer unter gewöhnlichem Druck arbeitenden kombinierten Ammoniakdestillation und -konzentration die durch Kongo densation der wasserhaltigen Ammoniakdämpfe gebildete Flüssigkeit zur Absorption des nach-35 It has now been shown that such ammonia-containing, pressurized gas mixtures, which can be described as difficult to condense, are advantageously treated with liquid absorbents, especially water, that the gases are co-current with the absorbents through pipes leads through. The absorption of ammonia, especially under pressure, has not yet been brought about by means of liquid absorbents introduced from the outside in cocurrent. It has rather been only at an operating under ordinary pressure combined ammonia distillation and concentration by Congo-condensation of the hydrous ammonia vapors formed liquid to absorb the post-35
strömenden wasserdampfhaltigen Ammoniaks benutzt.flowing ammonia containing water vapor is used.
Man kann vorteilhaft, wenn es sich darum handelt, die Gase von Ammoniak zu befreien und gleichzeitig konzentrierte Ammoniaklösung zu erhalten, so verfahren, daß man die Gase in der beschriebenen Weise mehrmals mit dem Absorptionsmittel behandelt, derart, daß zunächst eine bereits angereicherte Lösung mit dem Gasstrom in Berührung gebracht wird, worauf man die Flüssigkeit vom Gas trennt und letzteres z. B. in einer zweiten oder eventuell noch weiteren Apparatur mit weniger konzentrierter Lösung bzw. frischem Absorptionsmittel behandelt.It can be advantageous when it comes to removing ammonia from the gases and at the same time to obtain concentrated ammonia solution, proceed in such a way that the gases treated in the manner described several times with the absorbent, such that initially an already enriched solution is brought into contact with the gas flow, whereupon the liquid is separated from the gas and the latter z. B. in a second or possibly still further equipment with less concentrated solution or fresh absorbent treated.
