Title (EN) REMOVAL OF SULFUR CONTAMINANTS FROM HYDROCARBONS USING N-HALOGENO COMPOUNDS
(FR) ELIMINATION DES POLLUANTS A BASE DE SOUFRE CONTENUS DANS DES HYDROCARBURES PAR UTILISATION DE COMPOSES N-HALOGENO
Abstract:
(EN) The present invention is directed to a process for removal of sulfur contaminants from hydrocarbons using processes which rely upon the reaction of organosulfur compounds with N-halogeno compounds. The sulfur removal may be effected by using liquid/liquid extraction processes or one of two reactive adsorption processes involving injecting a stoichiometric amount of N-halogeno compounds into hydrocarbon and then passing the stream through an adsorbent column to adsorb the N-halogeno-sulfur compounds and any unreacted N-halogeno compounds; or using adsorbents which are pre-loaded with N-halogeno compounds which are placed in a fixed-bed column for sulfur removal.
(FR) L'invention se rapporte à un procédé qui sert à éliminer les polluants à base de soufre contenus dans des hydrocarbures grâce à l'utilisation de procédés qui se fondent sur la réaction des composés d'organosoufre avec des composés N-halogéno. On peut procéder à l'élimination du soufre en utilisant des procédés d'extraction liquide/liquide ou l'un des deux procédés d'adsorption réactive qui consistent à injecter une quantité st÷chiométrique de composés N-halogéno dans les hydrocarbures, puis à faire passer le flux d'hydrocarbures à travers une colonne adsorbante, afin d'adsorber les composés N-halogéno-soufre et tous les composés N-halogéno n'ayant pas réagi; ou en utilisant des adsorbants qui sont préalablement chargés des composés N-halogéno, lesquels sont alors placés dans une colonne à lit fixe pour l'élimination du soufre qu'ils contiennent.
