Abstract
Quench fluids being charged to a hydroprocessing reactor and liquid flowing downward within the reactor are admixed between the catalyst beds located in the reactor by an apparatus comprising three circular trays (16, 21, 22) and a mixing chamber (20). The mixing chamber receives liquid collected by the top tray and the quench material. The liquid effluent of the mixing chamber then falls upon a first distribution tray (21) while the vapor flows through an annular gap (17) between the first distribution tray (21) and the vessel wall (1). The two phases are then recontacted as they pass through a plurality of mixing caps (13) distributed over the surface of a lower second distribution tray (22).
