  • Process for the regeneration of an alkaline solution utilized in a process for the extraction of sulphur-containing compounds comprising a washing step
    Patent number: 10808182
    Abstract: The present invention relates to the field of the extraction of sulphur-containing compounds such as the mercaptans, COS or H2S 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.
    Type: Grant

  • Process for the regeneration of an alkaline solution used in a process for the extraction of sulphur-containing compounds not comprising a washing step
    Patent number: 10780398
    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.
