Abstract: Hydroprocessing reactor internals height reduction is achieved by placing a mixing chamber above the collection tray. The mixing chamber has spillways on the top (top spillways) and the side of the mixing chamber (side spillways) for fluid entry. The design of the spillways has a significant impact on pressure drop. The pressure drop is reduced by having wide shallow spillways rather than narrow and deep spillways without impacting mixing performance. With both side and top spillways, the height of the mixing chamber can be reduced significantly with minimal impact on fluid mixing and pressure drop.

Abstract: An apparatus in a radial reactor is described. The apparatus comprises a vertically elongated conduit extending around a circumference of an outer wall of the radial reactor, a vertically oriented cylindrical center pipe in the radial reactor, and a catalyst bed. The conduit comprises an inner face and an outer face and a pair of opposing sides. The inner face has a plurality of slots. The pair of opposing sides have a plurality of slots. There is a riser at a top of the vertically elongated conduit. The catalyst bed is defined by the center pipe and the inner face.
