ABSTRACT:
At least two feedstocks (210A) (210B) 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 (230A) (230B). 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.
