Abstract (en)
[origin: WO2013076383A1] The invention relates to a method for extracting sulphur compounds from an LPG- or petrol-type hydrocarbon fraction, by means of liquid-liquid extraction with a soda solution, using a pre-treatment unit (2) for pre-treating the feedstock to be treated, placed upstream of the soda-based extraction unit (4), said pre-treatment unit being formed by a first non-continuous pre-treatment reactor followed by a second piston-type continuous reactor operating in piston mode.
