WebJan 1, 2024 · An FCC unit is a “pressure balance” operation that behaves similar to a water manometer. Differential pressure between the regenerator and reactor vessels is the … 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.
WebWhen the severity in the FCC reactor was increased, problems were observed in operating the stripper and the debutaniser. The stripper had a higher and fluctuat-ing pressure drop, and the debutan-iser developed issues with boil-up. These symptoms forced the opera-tors to lower the unit capacity.
