Abstract
The present invention relates to the field of the extraction of sulphur-containing compounds such as the mercaptans, COS or HS from a hydrocarbon-containing cut. This selective extraction is carried out by bringing the hydrocarbon-containing cut in liquid phase into contact with an alkaline solution, for example soda. The process according to the invention is an improved process for the regeneration of the alkaline solution, making it possible to reduce the quantity of alkaline solution required in the regeneration section.
