FCCU operational and mechanical problems can be very widely due to the complexity and the dynamics of the process. There are common threads that link almost all units together such as Riser Cracking, full or complete combustion regeneration, stripping, reaction catalyst and fluidisation. The majority of the problems encountered are typically central to these shared elements. In most instances, problem resolution can be accomplished by a fundamental understanding of critical aspects in FCCU and application of some basic responses.
