Abstract: A separation column and a process for using same to separate a hydrocarbon or chemical mixture into at least a vapor stream and a liquid stream. The separation column includes an internal heat exchanger. The heat exchanger has a plurality of fins which allow for heat and mass transfer by including apertures. The fins may include louvers or perforations associated with the apertures to increase radial flow and permit fluids to flow through the fins. The heat exchanger may be used to supply heat to the column, remove heat from the column, or both.

Abstract: A high capacity and high efficiency co-current and cross-flow vapor-liquid contacting apparatus and process is useful in distillation columns and other vapor-liquid contacting processes. The apparatus is characterized by an arrangement of contacting modules and perforated receiving pans in horizontal stages. The modules define a co-current contacting volume and in an exemplary configuration the modules include a liquid distributor and a demister. Liquid dispensed from the modules on a perforated receiving pan are contacted with upflowing vapor through perforations therein.

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.
