WebNov 23, 1998 · The nozzles are designed for pressure drops of 2-5 bar (30-75 psi) and atomization steam rates of 1-3 wt % on feed. Higher atomization steam rates may be used for very heavy feeds. The low... WebThe FCCU WGC is generally centrifugal and discharges to a relatively fixed downstream pressure at all operating capacities. For compressors with steam turbine drivers, speed is varied to maintain the MF overhead pressure. For motor-driven compressors, this overhead pressure is controlled by throttling the WGC’s suction pressure.
WebThe FCC main fractionator was a traditional design with heavy cycle oil (HCO) pumparound, HCO wash, and slurry pumparound sections in the lower half of the fractionator. Successful operation of the HCO wash section became challenging due to requirements for heat removal when processing LTO feedstocks. WebDec 14, 2024 · There are three energy usage levels for wet scrubbers. A low energy wet scrubber utilizes pressure drops less than 5 inches of water column and are capable of efficiently removing particles greater than about 5-10 micrometers in diameter. A medium energy scrubber has a pressure drop from 5 to 25 inches of water column and is …
WebFCC unit operators must control the reactor-regenerator differential pressure Understanding unit pressure balance key to cost-effective FCC revamps PROCESSING Christopher F.Dean Saudi Arabian Oil Co. Dhahran Scott W.Golden Daryl W.Hanson Process Consulting Services Inc. Houston Refining WebThese simple process units basically consist of a large furnace that heats the feedstock to the range of 450 to 500 °C (840 to 930 °F) at an operating pressure of about 10 bars (1 MPa), or about 150 psi. The residence time in the furnace is carefully limited to prevent much of the reaction from taking place and clogging the furnace tubes.
