Abstract

L'invention concerne un procédé de désacidification d'huile brute consistant a) à mettre en contact l'huile brute et un solvant polaire, de telle façon qu'au moins une partie des acides organiques présents dans l'huile brute soit extraite par le solvant polaire sous forme de phase d'extraction, b) à séparer cette phase d'extraction de l'huile brute traitée dans l'étape a), c) à mettre en contact la phase d'extraction de l'étape b) et un matériau basique, pouvant réagir avec tout acide organique présent dans la phase d'extraction afin de donner un produit de neutralisation sensiblement insoluble dans le solvant polaire ou sensiblement immiscible dans ce solvant, et d) à récupérer le solvant polaire du produit de neutralisation.
