FCCU Process Fundamentals and Recent Developments

The FCCU is no longer just a fuels producer but is producing petrochemical feedstocks, pretreating tar sands and producing biofuels.

The FCCU can change operations from the production of large volumes of gasoline blending components (up to 70 volume percent of  the pool), to the production of large volumes of diesel blending components (up to 40 volume percent of the pool). The FCCU also  produces approximately 110 barrels of product for every 100 barrels of feed. With this range of demonstrated flexibility and volume  expansion, the FCCU is one of the most valuable process units in the refinery.

You Will Learn

Increase awareness of process fundamentals and operating principles for a broader understanding of the various FCC, RFCC and High Olefin FCC (HOFCC) unit process design differences, operating flexibilities and potential equipment revamp opportunities for more operating mode flexibility and future process development.

Who Should Attend

Unit operators and supervisors, refinery plant engineers, technical service and process engineers, both experienced and new to the FCC.

FCC equipment and process licensors, and service providers who want a better understanding of the FCC process can also benefit.


An understanding of refining processes and petroleum refinery terminology is expected, having some experience with the FCC unit is helpful.

Your Instructor

Christopher DeanChristopher F. Dean is an independent consultant with over 40 years in the refining business with an emphasis on High Olefin Fluid Catalytic Cracking (HOFCC) with petrochemical integration. His worldwide refining background includes the development and commercialization project of the High Severity-FCC Process both as a viable process and enhancements to existing FCC units for producing light olefins from heavy oils and naphtha, the development of the PetroRabigh integrated refinery and petrochemical joint venture complex, catalyst technical service in Europe and the US, process engineering, design and unit operations on a variety of refinery units with several refineries in the U.S., the Caribbean and the Middle East. He also initiated research and commercialization studies in catalytic naphtha cracking utilizing the HS-FCC downer reactor technology.

He has published over 40 papers and articles in technical journals, seminars, and conferences. He was recently granted patents on fluidized catalytic cracking of paraffinic naphtha in a downflow reactor and utilizing a downflow reactor as a revamp to existing FCC units for cracking heavy oil to produce propylene. He also has several patents on FCC gasoline desulfurization and a pending patent on cracking naphtha as a revamp to existing FCC units.

Chris is a graduate of West Virginia University with a BSChE and has completed graduate course work in Business Management, Finance, and Marketing.

He is the founder and principal consultant for High Olefins FCC Technology Services LLC.
