Fluid Catalytic Cracking Units

Fluid Catalytic Cracking FractionatorAlthough we do not service the FCCU reactor-regenerator, Process Consulting Services’ distillation expertise has led to many successful revamp and grassroots projects within the scope of the FCC main fractionator and gas plant. Our projects have included several FCC units with feed rates over 100 Mbpd.


The FCCU main fractionator and gas plant is usually designed by a licensor based on standard design procedures. Often these designs fail to maximize diesel recovery from lower value products. Losing diesel boiling range material to the naphtha, slurry, or HCGO products lowers refinery profitability. Process Consulting Services’ designs target maximum profitability rather than blindly adhering to standard practices.


Revamps can maximize gas plant performance with existing equipment. For example, a revamp may make use of structured packing to reduce fractionator pressure drop. The result is a higher compressor suction pressure that significantly increases gas handling without the need for an expensive compressor replacement. Gas plant C3+ recovery can materially influence overall refinery liquid volume recovery.
