Abstract A method for separating sulfur species from hydrocarbon streams, particularly cracked naphtha streams, using extractive distillation. The method effectively separates sulfur species from cracked naphtha streams without substantially lowering the olefin content. The process involves passing a feed through inlet (12) and a solvent through inlet (14) into a distillation column (10) in order to produce a solvent bottoms which contains the sulfur species and an overhead product. Cette invention concerne un procédé de séparation des espèces soufre présentes dans des flux d'hydrocarbures, en particulier dans des flux de naphta de craquage, par distillation extractive. Ce procédé permet de séparer efficacement les espèces soufre sans abaisser notablement la teneur en oléfines. Le procédé consiste à faire passer une charge par l'entrée (12) et du solvant par l'entrée (14) dans une colonne de distillation (10) pour produire une queue de solvant renfermant les espèces soufre et un produit de tête.
