Abstract

L'invention concerne un procédé de séparation inverse dans des systèmes de chambres d'hydrotraitement, qui comprend les étapes suivantes: a) envoi d'hydrocarbure (1) dans une zone de dénitrification et de désulfuration; b) envoi des effluents issus de ladite zone de dénitrification et de désulfuration dans une zone (20) de purification/refroidissement pour éliminer NH¿3? et H¿2?S et refroidissement, et récupération, à partir de ladite zone de purification/refroidissement, d'un courant (30) d'hydrogène/hydrocarbure léger et d'un courant liquide contenant des gaz dissous (35); c) envoi du dit courant liquide contenant des gaz dissous dans une zone (40) de séparation, et récupération d'un produit léger (45), de dépôts liquides (50) et d'au moins un produit latéral (52); d) envoi desdits dépôts liquides (50), dudit produit latéral (52) et dudit courant hydrogène/hydrocarbure léger (30) de l'étape b) dans une zone d'hydrocraquage ou d'hydrotraitement; e) évacuation des effluents (65) issus de ladite zone d'hydrocraquage ou d'hydrotraitement dans ladite zone (10) de dénitrification ou désulfuration.
