Abstract: front page image
(EN)The invention relates to a method for the recovery of oil from an aqueous solution containing oil and solids, as well as to the use of products obtained by this method. The method of the invention comprises at least the following steps of: Adjusting the oil- and solids-containing aqueous solution to a p H which is acidic, separating an oil- and solids-containing fraction from the acidic aqueous solution with an separation agent which is hydrophilic or assumes a hydrophilic character in response to water, recovering the oil- and solids-containing fraction separated by means of said separation agent, extracting oil away from the solids with a water-insoluble extraction agent, and recovering the oil-containing water-insoluble extraction agent.
(FR)L'invention porte sur un procédé pour la récupération d'huile à partir d'une solution aqueuse contenant de l'huile et des matières solides, ainsi que sur l'utilisation de produits obtenus par ce procédé. Le procédé de l'invention comprend au moins les étapes suivantes consistant à : ajuster la solution aqueuse contenant de l'huile et des matières solides à un pH qui est acide, séparer une fraction contenant de l'huile et des matières solides de la solution aqueuse acide à l'aide d'un agent de séparation qui est hydrophile ou qui prend un caractère hydrophile en réponse à l'eau, récupérer la fraction contenant de l'huile et des matières solides séparée au moyen dudit agent de séparation, extraire l'huile des matières solides à l'aide d'un agent d'extraction insoluble dans l'eau et récupérer l'agent d'extraction insoluble dans l'eau contenant de l'huile.
