A method for removing oil from oil-contaminated material comprising the steps of : a) reducing the particle size of oil-contaminated material using shearing means (112) to form reduced particle size material; b) mixing the reduced particle size material with a solution comprising a surfactant (20), wherein the surfactant (20) absorbs oil from the reduced particle size material; and c) separating the surfactant containing the absorbed oil from the reduced particle size material (34).
La présente invention concerne un procédé d'extraction d'hydrocarbures dans des substances contaminées par des hydrocarbures, consistant a) à réduire la taille des particules des substances contaminées par des hydrocarbures au moyen d'éléments de cisaillement (112) de manière à former des substances dont la taille des particules est réduite; b) à mélanger les substances dont la taille des particules est réduite à une solution contenant un tensioactif (20), le tensioactif (20) absorbant des hydrocarbures à partir des substances dont la taille des particules est réduite; et c) à séparer le tensioactif contenant les hydrocarbures des substances dont la taille des particules est réduite (34).
