A process separates a mixture of water, solids or sludges, non-volatile hydrocarbons, and other accompanying substances by means of solvent extraction. Mixtures that consist primarily of solids or sludge with non-volatile hydrocarbons are especially suited for application of this process, if they occur as a concentrated sludge from a settling pond of bitumen production from tar sands. However, it is also possible to use the process to decontaminate soil contaminated by crude oil spillage. The process makes it possible to process, and to break down to its primary constituents, the oil-bearing sludge that has accumulated during the production of bitumen from tar sands using the hot water method, and which is stored in settling ponds and constitutes a permanent danger to the environment. The recycled water is then free of hydrocarbons. This environmentally compatible process can be carried out with low energy and operation costs.
Procédé de séparation de mélanges d'eau, de matières solides ou de boues, d'hydrocarbures non volatils et d'autres matières au moyen d'un solvant. Le procédé visé convient particulièrement bien pour traiter des mélanges composés surtout de matières solides ou de boues et d'hydrocarbures non volatils si ces éléments se présentent sous forme de boue concentrée provenant d'un bassin de décantation de résidus de production de bitume d'une installation d'exploitation de sables bitumineux. Le procédé permet de traiter et de décomposer en ses composants primaires la boue à teneur de pétrole qui s'est accumulée au cours de la production de bitume dans des installations d'exploitation de sables bitumineux. Cette boue est stockée dans des bassins de décantation et constitue un danger permanent pour l'environnement. Après traitement, l'eau recyclée est exempte d'hydrocarbures. D'application peu coûteuse, ce procédé compatible avec l'environnement nécessite peu d'énergie.
