This invention relates to an improved hydrotreating process for removing sulfur from naphtha and distillate feedstreams. This improved process utilizes a hydrotreating zone, an acid gas removal zone, and a pressure swing adsorption zone having a total cycle time of less than about 30 seconds for increasing the concentration of hydrogen utilized in the process.
L'invention concerne un procédé d'hydrotraitement amélioré destiné à supprimer le soufre des charges de naphta et de distillat. Ce procédé amélioré fait appel à une zone d'hydrotraitement, à une zone de suppression de gaz acide, et à une zone d'adsorption modulée en pression, présentant une durée de cycle totale inférieure à 30 secondes environ, pour augmenter la concentration d'hydrogène utilisée dans le procédé de l'invention.
