Abstract

L'invention fournit un procédé de production d~un flux de gaz dépourvu de RSH à partir d'un flux de gaz d'alimentation comprenant du gaz naturel, RSH et des composés aromatiques choisis dans le groupe constitué par le benzène, le toluène, le o-xylène, le m-xylène et le p-xylène, le procédé comprenant les étapes consistant à : (a) mettre en contact le flux de gaz d'alimentation avec un liquide absorbant comprenant un solvant physique dans une zone d~élimination de composés aromatiques pour obtenir un liquide absorbant chargé comprenant des composés aromatiques choisis dans le groupe constitué par le benzène, le toluène, le o-xylène, le m-xylène et le p-xylène et un flux de gaz dépourvu de ces composés aromatiques ; (b) mettre en contact le flux de gaz obtenu dans l~étape (a) avec un adsorbant solide dans une zone d~élimination de mercaptans pour obtenir un adsorbant solide chargé de RSH et le flux de gaz dépourvu de RSH.
