Greater efciency, Safeguard Reactor Products Upgrades to FCC units typically increase catalyst circulation which elevates stripper catalyst ux rates. This increase signicantly reduces stripper efciency by entraining hydrocarbon product gases into the regenerator. Once entrained, regenerator temperatures rise requiring the stripper to use additional combustion air while more hydrocarbon product is burned and lost. Managing Flux Rates KBR DynaFlux™ stripping technology addresses two challenges seen in conventional strippers: high local catalyst ux and poor lateral mixing. Developed jointly by KBR and ExxonMobil, DynaFlux technology allows the FCC stripper to effectively manage elevated ux rates. DynaFlux
