TWO STAGE HYDROTREATING OF DISTILLATES WITH IMPROVED HYDROGEN MANAGEMENT

摘要

An improved hydrotreating process for removing sulfur from distillate boilin g range feedstreams. This improved process utilizes a two stage hydrotreating process scheme, each stage associated with an acid gas removal zone wherein one of the stages utilizes a rapid cycle pressure swing adsorption zone to increase the concentration of hydrogen in the process.
