Title (EN) NAPHTHA DESULFURIZATION PROCESS
(FR) PROCEDE DE DESULFURATION DU NAPHTA
Abstract:
(EN) This invention relates to a process for selectively desulfurizing naphtha. More particularly, a low sulfur naphtha feed containing less than 500 wppm sulfur is hydrodesulfurized using a hydrodesulfurization catalyst and a hydrogen treat gas containing at least 50 vppm hydrogen sulfide followed by mercaptan removal or conversion.
(FR) L'invention concerne un procédé permettant la désulfuration sélective du naphta. De manière plus spécifique, ce procédé consiste à hydrodésulfurer une charge de naphta faiblement sulfurée contenant moins de 500 ppm en masse de soufre, au moyen d'un catalyseur d'hydrodésulfuration et d'un gaz de traitement hydrogéné contenant au moins 50 ppm en volume de sulfure d'hydrogène, puis à procéder à l'élimination ou à la conversion des mercaptans.
