Description

Die Erfindung betrifft ein verbessertes Verfahren zur Bergung hochviskoser Produkte gemäß Patent 44 38 269.The invention relates to an improved method for Recovery of highly viscous products according to the patent 44 38 269.

In dem Patent 44 38 269 wird ein Ver­ fahren zur Bergung hochviskoser Produkte, die insbe­ sondere bei der Verarbeitung von Mineralölen, Hydro­ raffinaten, Altölen, Teeren und anderen Kohlenwasser­ stoffen entstehen und als Abfallprodukte in Becken, Gruben, Behältern u. a. deponiert oder gelagert werden, beschrieben, bei dem durch Einbringung von Zusatzmit­ tel eine pumpfähige Konsistenz dieser Produkte er­ reicht wird. Als Zusatzmittel werden dazu flüssige Koh­ lenwasserstoffgemische mit einer Viskosität von minde­ stens 4 mm2/s bei 20°C oder Wasser vorgeschlagen, die bis zu 10 Ma.-Teile Tenside oder andere geeignete ober­ flächenaktive Stoffe enthalten können.In the patent 44 38 269 a method for the salvage of highly viscous products, which arise in particular in the processing of mineral oils, hydro raffinates, waste oils, tars and other hydrocarbons and are deposited or stored as waste products in basins, pits, containers, etc. described, in which a pumpable consistency of these products is achieved by introducing additives. Liquid carbohydrate mixtures with a viscosity of at least 4 mm 2 / 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 Patent 44 38 269 hat es sich nun erfindungsge­ mäß als vorteilhaft erwiesen, zur Verbesserung der Pumpfähigkeit insbesondere hochviskoser säurehaltiger Produkte mit Säuregehalten zwischen 10 und 40 Ma.-% als Zusatzmittel eine wäßrige alkalische Lösung bzw. Suspension zu verwenden. Besonders vorteilhaft hat sich dabei die Verwendung einer calciumhydroxidhalti­ gen wäßrigen Suspension mit Calciumhydroxidgehalten von 0,1 bis zu 22 Ma.-% erwiesen.When performing the process according to patent 44 38 269 it has now fiction Moderately proven to improve Pumpability especially high-viscosity acidic Products with acid contents between 10 and 40% by mass as an additive an aqueous alkaline solution or Suspension to use. Has particularly advantageous the use of a calcium hydroxide content against aqueous suspension with calcium hydroxide contents from 0.1 to 22% by mass.

Dabei hat sich gezeigt, daß bei der Anwendung des erfindungsgemäßen Verfahrens deponierte hochviskose säurehaltige Produkte im Rahmen der angegebenen Säurekonzentrationen überraschend gut in eine pump­ fähige Konsistenz unter Vermeidung von Klumpenbil­ dung überführt werden können. Darüber hinaus hat es sich als vorteilhaft erwiesen, daß bei der Anwendung der Erfindung ein Zusau von Tensiden gegenüber der im Hauptpatent vorgeschlagenen Verfahrensvarianten nicht mehr erforderlich ist.It has been shown that when using the The inventive method deposited highly viscous acidic products within the specified Acid levels surprisingly well in a pump capable consistency while avoiding clumping can be transferred. It also has proved to be advantageous in the application the invention a view of surfactants against the process variants proposed in the main patent is no longer required.

Die Erfindung soll nachstehend an einem Ausfüh­ rungsbeispiel näher erläutert werden:
1000 kg Säureharz mit einem Schwefelsäuregehalt von 29,5 Ma.-% und einer Viskosität von 10300 mm2/s werden gemäß Patent 44 38 269 ge­ borgen, 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 pumpba­ re Konsistenz aufweist.The invention will be explained in more detail below using an exemplary embodiment:
1000 kg of acid resin with a sulfuric acid content of 29.5% by mass and a viscosity of 10,300 mm 2 / s are borrowed according to patent 44 38 269, whereby an alkaline liquid consisting of 3000 kg water and 230 kg techn. Hydrated lime is used. The result is a thin, aqueous suspension with a good pumpable consistency.
