FIELD: chemistry.
SUBSTANCE: present invention relates to the field of extraction of sulfur compounds, such as mercaptans, COS or H2S, from hydrocarbon fraction. This selective extraction is carried out by bringing into contact hydrocarbon fraction in a liquid phase with alkaline solution, for example sodium hydroxide.
EFFECT: method, according to the invention, is an improved method for regeneration of alkaline solution that allows for the reduction of alkaline solution amount required in regeneration section.
