    摘要： Trays having increased capacity and efficiency are described. The trays have a deck, and downcomers extending through the deck. There are a plurality of bubble promoters on the deck. Each bubble promoter defines a zone on the deck, and the zone has an opening in the deck. The opening is positioned adjacent to a solid support for the tray. The bubble promoters provide areas through which vapor can pass, turning blocked areas of the tray into active areas. Mass transfer columns containing the trays are also described.

    摘要： 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 and reactor pressure drop. More particularly, a scale collection device is in an upper portion of a reactor vessel above a rough liquid distribution tray and a vapor-liquid distribution tray.

    摘要： Multiple downcomer trays having increased active area for vapor-liquid contact and separation are described. The increased active area of the tray is achieved by adding raised bubble promoters surrounded by perforated vertical contactors on the tray deck. The bubble promoters and surrounding vertical contactors are located under the downcomers from the tray above. The bubble promoter and surrounding vertical contactor promote uniform fluid flow and contact.

    摘要： 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.

    摘要： A fluid distribution device is presented for the collection and distribution of fluid between reactor beds. According to various aspects, the device includes a collection tray, a mixing chamber in fluid communication with the collection tray, a rough distribution tray in fluid communication with the mixing chamber, and a fine distribution tray in fluid communication with the rough distribution tray. The rough distribution tray includes a vapor chimney.

    摘要： Separation processes and separation apparatus are described. The process includes introducing a stream of liquid containing dispersed droplets of another liquid into a separation apparatus comprising a vessel having at least one mesh screen covering substantially all of the cross-section of the vessel. The mesh screen is periodically slightly moved so that the wires of the mesh screen contact the dispersed droplets and some of the dispersed droplets coalesce on the wires. The coalesced droplets rise or fall from the wires through the stream of the second liquid. The coalesced droplets are collected in a portion of the vessel. A stream of the second liquid having a reduced level of dispersed droplets is recovered.
