New Technologies and Potential Opportunities for FCC Revamps

Resid UnitThe FCC unit is one of the most flexible operating processes in a refinery to produce a variety of products from gasoline and olefins to large quantities of diesel blending stocks from various opportunity feedstocks. Different process unit designs for various product modes of maximum gasoline, maximum distillate, and high olefin production all have a certain degree of operating flexibility to produce a variety of products from various feedstocks.

Key areas for determining potential opportunities are a detailed understanding of the process variable effects on unit severities and product selectivities and what unit hardware changes are needed to provide maximum product flexibilities from various opportunity feedstocks.

The New Technologies and Potential Revamp Opportunities (One Day Course), offered at RefComm® Budapest on 6 October 2017, will focus on the detail operating variables and potential key equipment hardware changes that would be required for existing units to gain the maximum benefits from potential revamp opportunities. Additional discussions will include different catalysts and catalyst systems, main column fractionation and gas concentration recovery plant changes and one area that is routinely ignored in revamp studies, the treating section for the final products.Second Reaction Zone

Christopher 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.
