Marathon Petroleum Co.’s (MPC’s) Catlettsburg fluid catalytic cracking unit (FCCU) experienced a catalyst circulation constraint due to partial blockage of an intra-regenerator standpipe. The unit was initially debottlenecked by introducing torch oil, along with increased catalyst addition, to maintain unit activity. The refinery then introduced a high-activity co-catalyst into the FCCU. 1 The co-catalyst solution allowed removing the torch oil while maintaining catalyst activity, thus optimizing the FCCU’s profitability within the catalyst circulation limit. The cost of the co-catalyst is minor, while the direct measured value creation at the Catlettsburg refinery was over $1/bbl.
