Abstract

The process for recovering highly viscous products from dumps or other storage areas (P4438269.3-24) comprises using an alkaline soln. as an additive. Reactive lime is pref. used as an additive, in an amt. of 0.1-22 wt.%

Description

Die Erfindung betrifft ein verbessertes Verfahren zur Bergung hochviskoser Produkte gemäß Patentanmeldung P 44 269.3-24
In der Patentanmeldung P 44 38 269.3-24 wird ein Verfahren zur Bergung hochviskoser Produkte, die insbesondere bei der Verarbeitung von Mineralölen, Hydroraffinaten, Altölen, Teeren und anderen Kohlenwasserstoffen entstehen und als Abfallprodukte in Becken, Gruben, Behältern u. a. deponiert oder gelagert werden, beschrieben, bei dem durch Einbringung von Zusatzmittel eine pumpfähige Konsistenz dieser Produkte erreicht wird. Als Zusatzmittel werden dazu flüssige Kohlenwasserstoffgemische mit einer Viskosität von mindestens 4 mm²/s bei 20°C oder Wasser vorgeschlagen, die bis zu 10 Ma.-Teile Tenside oder andere geeignete oberflächenaktive Stoffe enthalten können.The invention relates to an improved method for recovering highly viscous products according to patent application P 44 269.3-24
Patent application P 44 38 269.3-24 describes a process for recovering highly viscous products, which are produced in particular when processing mineral oils, hydroraffinates, waste oils, tars and other hydrocarbons and are deposited or stored as waste products in basins, pits, containers and others , in which a pumpable consistency of these products is achieved by adding additives. Liquid hydrocarbon mixtures with a viscosity of at least 4 mm² / s at 20 ° C. or water are proposed as additives, which may contain up to 10 parts by weight of surfactants or other suitable surface-active substances.

Bei der Durchführung des Verfahrens gemäß Patentanmeldung P 4438269.3-24 hat es sich nun erfindungsgemäß als vorteilhaft erwiesen, zur Verbesserung der Pumpfähigkeit insbeson­ dere hochviskoser säurehaltiger Produkte mit Säuregehalten zwischen 10 und 40 Ma.-% als Zusatzmittel eine wäßrige alkalische Lösung bzw. Suspension zu verwenden. Besonders vor­ teilhaft hat sich dabei die Verwendung einer calciumhydroxidhaltigen wäßrigen Suspension mit Calciumhydroxidgehalten von 0,1 bis zu 22 Ma.-% erwiesen.When carrying out the method according to patent application P 4438269.3-24, it was now proven to be advantageous according to the invention, in particular to improve pumpability their highly viscous acidic products with acid contents between 10 and 40% by mass as Additive to use an aqueous alkaline solution or suspension. Especially before The use of an aqueous suspension containing calcium hydroxide has also been of some benefit Calcium hydroxide contents from 0.1 to 22% by mass have been proven.

Dabei hat sich gezeigt, daß bei der Anwendung des erfindungsgemäßen Verfahrens deponierte hochviskose säurehaltige Produkte im Rahmen der angegebenen Säurekonzentrationen überraschend gut in eine pumpfähige Konsistenz unter Vermeidung von Klumpenbildung überführt werden können. Darüber hinaus hat es sich als vorteilhaft erwiesen, daß bei der Anwendung der Erfindung ein Zusatz von Tensiden gegenüber der im Hauptpatent vorge­ schlagenen Verfahrensvarianten nicht mehr erforderlich ist.It has been shown that when using the method according to the invention deposited highly viscous acidic products within the specified acid concentrations surprisingly good in a pumpable consistency while avoiding clumping can be transferred. In addition, it has proven to be advantageous in that Application of the invention an addition of surfactants compared to that in the main patent proposed process variants is no longer required.

Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden:The invention will be explained in more detail below using an exemplary embodiment:

1000 kg Säureharz mit einem Schwefelsäuregehalt von 29,5 Ma.-% und einer Viskosität von 10300 mm²/s werden gemäß Patentanmeldung P 44 38 269.3-24 geborgen, wobei als Löse- Trägerflüssigkeit eine alkalische Flüssigkeit bestehend aus 3000 kg Wasser und 230 kg techn. Kalkhydrat verwendet wird. Es entsteht eine dünnflüssige, wäßrige Suspension, die eine gut pumpbare Konsistenz aufweist.1000 kg of acid resin with a sulfuric acid content of 29.5 mass% and a viscosity of 10300 mm² / s are recovered in accordance with patent application P 44 38 269.3-24.  Carrier liquid an alkaline liquid consisting of 3000 kg water and 230 kg techn. Hydrated lime is used. The result is a thin, aqueous suspension that is good has pumpable consistency.
