Apparatuses for processing a hydrocarbonaceous feedstock flows are provided. In one aspect, the method includes providing two or more hydroprocessing stages disposed in sequence, each hydroprocessing stage having a hydroprocessing reaction zone with a hydrogen requirement and each stage in fluid communication with the preceding stage. A hydrogen source is provided substantially free of hydrogen from a hydrogen recycle compressor. The hydrocarbonaceous feedstock flow is separated into an portions of fresh feed for each hydroprocessing stage, and the first portion of fresh feed to the first hydroprocessing stage is heated. The heated first portion of fresh feed is supplied with hydrogen from the hydrogen source in an amount satisfying substantially all of the hydrogen requirements of the hydroprocessing stages to a first hydroprocessing zone. The unheated second portion of fresh feed is admixed with effluent from previous stage to quench the hot reactor effluent before entering a second stage.
