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: A crude distillation and refining process and apparatus enables modular supply of the crude distillation column. Crude oil may be heated and then separated into only two liquid products in the crude distillation column. The separation between the light and heavy products may be controlled by the overhead product flow rate. Heat is recovered from an overhead stream and a bottoms stream by pre-heating the incoming crude oil stream by heat exchange with overhead stream and the bottoms stream. In an embodiment, a diesel-range distillate fraction may be condensed from an overhead stream in a first heat exchanger and a naphtha-range fraction may be condensed from the gas stream uncondensed by the first heat exchanger in a second heat exchanger.

Abstract: Methods for processing a hydrocarbonaceous feedstock flows are provided. In one embodiment, 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. The hydrocarbonaceous feedstock flow may be separated into 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 may be 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 injected counter current to the process flow as quench at one or more locations in one or more of the reaction zones.

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.
