Abstract Systems and processes for removing sulfur compounds from a hydrocarbon stream. Sulfur compounds are extracted from a hydrocarbon feed stream with a caustic stream to provide a treated hydrocarbon stream and a rich caustic stream. The sulfur compounds in the rich caustic stream are oxidized in the presence of a catalyst to provide a lean caustic stream. The lean caustic stream is returned to extract sulfur from the hydrocarbon stream. Data such as a concentration of sulfurs species and degree of caustic saturation with the sulfur species in the rich caustic stream may be provided by a sensor, compared against other real-time or historical data and used to provide a recommended adjustment to process conditions associated with an extraction unit, or an oxidation unit, or both. Systèmes et procédés permettant d?éliminer des composés du soufre d?un courant d?hydrocarbures. Des composés du soufre sont extraits d?un courant de charge d?hydrocarbures à l?aide d?un courant caustique pour donner un courant d?hydrocarbures traité et un courant caustique riche. Les composés du soufre dans le courant caustique riche sont oxydés en présence d?un catalyseur pour donner un courant caustique pauvre. Le courant caustique pauvre est renvoyé pour extraire le soufre du courant d?hydrocarbures. Les données telles qu?une concentration en espèces du soufre et le degré de saturation caustique en espèces du soufre dans le courant caustique riche peuvent être fournies par un capteur, par comparaison avec d?autres données en temps réel ou historiques et utilisées pour fournir un ajustement recommandé des conditions du procédé associées à une unité d?extraction, ou à une unité d?oxydation, ou aux deux.
