Beschreibung
Zusammenfassung:	The present disclosure relates to a process for reducing the sulphur content of hydrocarbon feedstocks such as Natural Gas Condensate, Kerosene, Jet Fuel, Diesel, Vacuum Gas Oil and Fuel Oil. The process uses a tailored oxidation process comprising one or two oxidation steps to produce sulphoxides and/or sulphones. These sulphoxides and sulphones, while being still present in the liquid hydrocarbon streams, are subsequently extracted thereby producing a low sulphur hydrocarbon stream and optionally following further treatment of the sulphoxides and/or sulphones, produce a low sulphur aromatic hydrocarbon stream and an aqueous stream of sodium sulphite or sulphuric acid. The low sulphur hydrocarbon stream and low sulphur aromatic hydrocarbon stream may be individually recycled or combined for recycling.
