The fluid catalytic cracking unit (FCCU) is usually the most profitable unit in the refinery. A systematic approach to optimizing FCCU operations for improving yields and operating efficiency can turn a refinery loss into a profit. Sampling techniques for the riser, reactor, stripper and effluent line help the refiner get a clear picture of current yields and identity potential benefits of new technologies for feed distribution, short contact time systems and catalyst oil separation equipment (i.e., closed cyclones). Methods for selecting the optimum FCC catalyst and operating conditions focus on maximum throughput through the FCCU at maximum severity. In order to accomplish this task, a refiner must develop a strategy to force the FCCU to consistently run up against several operating constraints simultaneously. New technologies will help refiners handle FCC feed metals more efficiently. These include the latest developments in magnetic separation technology and a new FCC feed additive that enhances catalyst activity, selectivities and bottoms cracking activity, especially in the presence of metals.
