Abstract: Heat exchangers (also referred to as exchangers herein) are provided that fit within a bottom sump of a distillation column. These heat exchangers may be at least partially submerged in the bottoms fluid of the distillation column so that the exterior surface of the heat exchanger can contribute to the total area of the heat exchanger. The internal configuration of the exchanger allows for annular coaxial flow of the hot fluid (condensing vapor stream) and eliminates the need for top and bottom channel heads.

Abstract: A high capacity and high efficiency vapor-liquid contacting apparatus and process is useful in distillation columns and other vapor-liquid contacting processes. The apparatus is characterized by a half module comprising a downcomer against a shell of a vessel for transporting liquid to a subjacent stage which utilizes a demister to effect vapor-liquid separation at the downcomer outlet.

Abstract: Distillation trays having improved efficiency and capacity are described. The improvement is accomplished with unique downcomer spout arrangements and bubble promoters which provide equal liquid distribution to all areas of the tray. The ratio of the open area of a contacting zone including part of a bubble promoter and associated deck zone over the open area of the downcomer spout zone on the adjacent tray for distributing liquid to the zone is essentially the same across the tray.

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 contacting device and method are presented for the collection, contacting, and distribution of fluids between particulate beds of a downflow vessel, which may operate in co-current flow. By one approach, the contacting device includes a liquid collection tray, a mixing channel in fluid communication with the liquid collection tray, and a liquid distribution zone.

Abstract: The hydroprocessing reactor internals (HRI) have reduced height compared to standard HRI designs. The HRI height reduction is achieved by a more open design of a rough liquid distribution tray so that the required spaces above and below the tray for vapor flow are reduced. The hydroprocessing reactor quench zone internals comprise a collection tray, a rough liquid distribution tray, and a vapor-liquid distribution tray. Fluid mixing occurs above both the collection tray and the rough liquid distribution tray.

Abstract: The hydroprocessing reactor internals (HRI) have reduced height compared to standard HRI designs. In this design, HRI height reduction is achieved by placing a mixing chamber above the collection tray. A ring quench distributor is located around the fluid collection tray between the mixing chamber and reactor shell to eliminate the vertical space occupied by the distributor. The hydroprocessing reactor quench zone internals comprise a collection tray, a mixing chamber, a ring distributor, a rough liquid distribution tray, and a vapor-liquid distribution tray. Fluid mixing occurs in the mixing chamber and above the rough liquid distribution tray.

Abstract: The invention involves a scale collection device that is located within downflow reactor head for removing solids from feed streams to increase reactor operating cycle time without impact on effective reactor space for catalyst loading. More particularly, a filtering zone is located in an upper portion of a reactor vessel above a rough liquid distribution tray and a distribution tray.
