Technology

UOP licensed Catalytic Cracking Processes include ^[1]

• Fluid Catalytic Cracking (FCC) Process,
• Resid FCC (RFCC) Process (targeted for Residual Feeds greater than 4 Wt% Conradson Carbon).
• MSCC℠ Process (Developed by BARCO and licensed exclusively by UOP).
• PetroFCC℠ Process (converts VGO, HVGO, and hydrocracked gas oil, capable of producing a product slate of 18 wt-% propylene and 5 wt-% ethylene).

All of these Processes convert Gas Oil and Heavier Streams to lighter, more valuable Products via High-Temperature Catalytic Cracking.
A Fluidized Catalyst System is used to facilitate Catalyst and heat transfer between the Reactor and Regenerator. The System is heat-balanced: Combustion of Coke in the Regenerator provides all the heat necessary for the Reactor ^[1].

Based on conventional, proven Technology, the FCC Process features elevated Optimix™ Feed Distributors, the Vortex Separation System℠ (VSS℠) Riser Termination Device and a Bustor Style Regenerator. Catalyst Coolers, the RxCat℠ Design and Selective Recycle can be added to increase flexibility for Feed and Product demands ^[1].
