Description

Verfahren zur Herstellung eines hydraulischen Bindemittels aus Ölschiefer und Kalkstein. Zusatz zum Patent q.2780=. Das Patent 427801 betrifft die Herstellung von hydraulischen Bindemitteln aus Ölschiefer, wobei gleichzeitig mit dem Zementbrennen Destillationsprodukte des Ölschiefers erzeugt bzw. gewönnen werden. Es wird dabei mit einem möglichst großen Kalkstein-oder Kalkmergel- o. dgi. Zusatz gearbeitet. Einen Teil der Destillationsprodukte aus dein Ölschiefer bildet ammoniakhaltiges Schwelwasser, dessen wirtschaftliche Gewinnung von nicht zu unterschätzender Bedeutung für <las ganze Verfahren ist.Process for the production of a hydraulic binder from oil shale and limestone. Addition to the patent q.2780 =. The 427801 patent relates to manufacturing of hydraulic binders made from oil shale, taking place simultaneously with the cement burning Distillation products of the oil shale are produced or recovered. It will be there with the largest possible limestone or lime marl o. dgi. Worked addition. Part of the distillation products from your oil shale is ammonia-containing Smoldering water, the importance of which should not be underestimated for economic production for <the whole procedure is.

Die vorliegende Erfindung betrifft eine Ausgestaltung des Verfahrens, bei der das im Schwelwasser enthaltene Ammoniak fast kostenlos gewonnen wird.The present invention relates to an embodiment of the method in which the ammonia contained in the smoldering water is obtained almost free of charge.

Überraschenderweise wurde gefunden, daß. ein plötzliches, schnelles Löschen bei dein nach Patent q.27801 erhaltenen Brenngut nicht vorteilhaft ist. Dieses ist vielleicht darauf zurückzuführen, daß das anfallende Brenngut inhomogen ist und aus nebeneinanderliegenden Kalk- und Silikatstoffen besteht. Im Gegensatz ztc den bisher geltenden Vorschriften erfolgt also die Löschung des gebrannten Kalkes nicht durch reines Wasser, sondern nach der Erfindung wird unmittelbar mit dem aus clen Destillationsprodukteci des ülschiefers stammenden ammoniakhaltigen Schwelwasser gelöscht, und zwar unter solchen Bedingungen, daß gleichzeitig das Ammoniak des Schwelwassers gewonnen wird.Surprisingly, it has been found that. a sudden, quick one Deleting your firing material obtained according to patent q.27801 is not advantageous. This is perhaps due to the fact that the material to be fired is inhomogeneous and consists of adjacent lime and silicate substances. In contrast In accordance with the regulations in force so far, the quick lime is extinguished not by pure water, but according to the invention is made directly with the The distillation products of the ammonia-containing smoldering water originating from the oil slate deleted, under such conditions that at the same time the ammonia des Schwelwassers is obtained.

Das geschieht in der Weise, daß das Löschen in geschlossenen Gefäßen oder Räumen, die mit Gasabführung versehen sind, vorgenommen wird. Durch den Kalk wird das Ammoniak aus seinen Verbindungen freigemacht. Die chemische Reaktion des gebrannten Kalkes mit dem Wasser entzieht einerseits dem freien bzw. frei gewordenen Ammoniak das Lösungswasser, anderseits fördert die bei der Hydratisierung des Kalkes entstehende Wärme die Austreibung des Ammoniaks, so daß letzteres fast restlos gewonnen werden kann. Natürlich geht das Ammoniak mit Wasserdampf gemischt über, es ist jedoch bereits stark konzentriert. Ohne besondere Aufwendungen kann es sodann in bekannter Weise auf verdichtetes Ammoniakwasser oder auf Ammonsulfat verarbeitet werden.This is done in such a way that the extinguishing in closed vessels or rooms that are provided with gas discharge. Through the lime the ammonia is released from its compounds. The chemical reaction of the Burnt lime with the water on the one hand withdraws what is free or what has become free Ammonia the water of solution, on the other hand it promotes the hydration of the lime The resulting heat expels the ammonia, so that the latter is almost completely recovered can be. Of course, the ammonia passes over mixed with water vapor, but it is already highly concentrated. Without any special expenses it can then be used in a well-known manner Way to be processed on compressed ammonia water or on ammonium sulphate.

Das neue Verfahren schließt bedeutsame Vorteile in sich. Einmal sind besondere Apparaturen überflüssig. Ebensowenig wird eine Zuführung von Energie benötigt und trotzdem aus dem sehr verdünnten Ammoniakwasser die Gewinnung des Ammoniaks in wirtschaftlicher Weise, Eermöglicht. Am wichtigsten ist aber, daß das Schwelwasser auf den erbrannten Mörtelbildner infolge seines Teer- und Ammoniakgehaltes verbessernd wirkt. Das Löschgut zeigt ein günstiges Abbindev erhalten, und außerdem besitzt der erhaltene Mörtelbildner wasserabweisende Eigenschaften.The new process has significant advantages. Once are special equipment is superfluous. Neither is there any need for energy to be supplied and still from the very dilute ammonia water the extraction of ammonia in an economical way. Most importantly, that the smoldering water on the burnt mortar former due to its tar and ammonia content has an improving effect. The extinguishing material shows a favorable Abbindev received, and moreover the mortar former obtained has water-repellent properties.
