Abstract:
Process of extracting sulphur-containing compounds from a hydrocarbon cut of the gasoline or LPG type by liquid-liquid extraction with a soda solution employing a unit (2) for pretreatment of the feedstock to be treated placed upstream of the extraction unit (4), the soda being introduced into the extraction column (4) in the form of two circuits operating either in parallel, or in series.
