Abstract: The present invention relates to the field of extraction of sulphur-containing compounds such as mercaptans, COS, H2S or CS2 from a hydrocarbon cut. This selective extraction is carried out by bringing the hydrocarbon cut in the liquid phase into contact with an alkaline solution, for example caustic soda. The process in accordance with the invention is an improved process for the regeneration of alkaline solution which can be used to reduce the quantity of alkaline solution necessary in the regeneration section.
