Bottoms product from fluidized catalytic cracking (FCC) is typically one of the least valuable products from a refinery.
Refiners are continually challenged to maximize economic gain in the face of cost pressures and plant operating constraints. The fluidized catalytic cracking unit (FCCU) plays an integral role in the optimization of the facility. FCC catalyst is often one of the largest budget items in the refinery. Therefore, the balance between FCCU performance and catalyst costs has a significant impact on refinery profitability.
