Combined hydrotreating process and configurations for same

摘要

At least two feedstocks ( 210 A) ( 210 B) with different boiling point ranges are hydrotreated in an integrated hydrogenation plant ( 200 ) using an interbed separator ( 240 ) that is fluidly coupled between two hydrogenation reactors ( 230 A) ( 230 B). Contemplated configurations and methods will significantly reduce construction and operating cost by integration of at least two hydrogenation processes of two different feedstocks into one process, and/or by providing process conditions that reduce use of catalyst in at least one of the reactors.
