Description

Verfahren zur Verarbeitung roher Ammoniakwässer. Das Hauptpatent 397466 bezieht sich auf die Reinigung roher Ammoniakwässer mittels organischer Lösungsmittel, die die im Wasser suspendierten und gelösten Stoffe, z. B. Phenole und Basen, herauslösen und so ein reines Ammoniakwasser erzielen; im besonderen besteht die Erfindung darin, die Wirtschaftlichkeit des Verfahrens in quantitativer und qualitativer Weise zu erhöhen, einmal, indem die beim Abtreiben mitübergegangenen Lösungsmittelreste zurückgewonnen werden, und zum anderen, indem eine vorherige Teerscheidung vorgesehen wird.Process for processing raw ammonia water. The main patent 397466 refers to the purification of raw ammonia water using organic solvents, the suspended and dissolved substances in the water, e.g. B. phenols and bases, dissolve and thus achieve a pure ammonia water; in particular, the invention consists in the economic efficiency of the process in quantitative and qualitative manner Increase, once, by recovering the residual solvent that was carried over during the stripping process and on the other hand, by providing for a prior tar separation.

Gemäß der vorliegenden Weiterbildung wird nun der Gedanke der Hauptanmeldung noch dadurch vervollkommnet, daß die Behandlung des Rohwassers mit den organischen wasserunlöslichen Lösungsmitteln bei erhöhter Temperatur vorgenommen wird, womit ebenfalls der Gedanke der möglichst vollkommenen Rückgewinnung des Lösungsmittels eine Verbesserung erfährt. Zunächst geht bei der Erwärmung die Lösung selbst rascher vor sich, was bei den großen zu verarbeitenden Wassermengen, die verhältnismäßig wenig Verunreinigungen enthalten, von größter Bedeutung ist. Ferner ist die anteilige Auslösung der Stoffe günstiger, und zwar trotz der Tatsache, daß bei gesteigerter Temperatur auch die Lösefähigkeit des Wassers wächst. Schließlich erfolgt die Trennung des Lösungsmittels vom Wasser rascher, womit die Lösungsmittelverluste auf ein Mindestmaß herabgesetzt werden.According to the present development, the idea of the main application is now still perfected by the fact that the treatment of the raw water with the organic water-insoluble solvents is made at elevated temperature, with which also the idea of the most complete possible recovery of the solvent experiences an improvement. First of all, the solution itself goes faster when it is heated in front of you, what with the large quantities of water to be processed, the proportionate contain few impurities, is of the utmost importance. Furthermore, the pro rata Triggering the substances more favorable, despite the fact that with increased Temperature also increases the solvency of the water. Finally the separation takes place the solvent from the water more quickly, so that the solvent losses to a minimum be reduced.

:Ein weiterer Vorteil besteht darin, daß Emulsionen, zu denen fast alle Lösungsmittel neigen, und die natürlich größere Verluste bedingen, rasch verschwinden. Es können somit auch hier Lösungsmittel zur Anwendung kommen, die bisher wegen zu großer Emulgierbarkeit ausgeschlossen waren. Damit betragen die Verluste an Lösungsmitteln sowohl durch wirkliche Lösung als auch durch Emulsionen nach dem Gesamtverfahren nur noch einen kleinen Bruchteil der bisherigen, womit die Wirtschaftlichkeit des Verfahrens verbürgt erscheint.: Another advantage is that emulsions to which almost all solvents tend, and which naturally cause greater losses, quickly disappear. Solvents can therefore also be used here, which were previously due to great emulsifiability were excluded. This increases the loss of solvents both by real solution and by emulsions according to the overall process only a small fraction of the previous one, which means that the Proceedings appear guaranteed.
