A process for reducing the Mutagenicity Index and/or the PCA content of a lubricating oil extract by re-extracting a lubricating oil extract with a second extraction solvent, different from the first extraction solvent, to form a secondary raffinate and a secondary extract mix; separating the secondary raffinate from the secondary extract mix; and separating the secondary raffinate and the secondary extract from said second extraction solvent.
L'invention concerne un procédé visant à réduire l'indice de mutagénicité et/ou la teneur en hydrocarbures aromatiques polycycliques d'une huile lubrifiante, par réextraction d'un extrait d'huile lubrifiante avec un second solvant d'extraction, différent du premier, de manière à former un raffinat secondaire et un mélange d'extraits secondaire. Ledit procédé consiste ensuite à séparer le raffinat secondaire du mélange d'extraits secondaire, et à séparer le raffinat secondaire et l'extrait secondaire du second solvant d'extraction.
