Dynamic Simulation of a Fluid Catalytic Cracking Unit. Predicting the Operation Using a Hydrotreated Feed

E-mail Print

Fluid Catalytic Cracking (FCC) has been used for more than 60 years in order to convert straight-run atmospheric gas oils, vacuum gas oils, atmospheric residues, and heavy stocks recovered from other refinery operations into high-octane gasoline, light fuel oils and olefin-rich light gases. Due to the complexity of the process itself, and the need for efficient ways of handling various feedstock, a rigorous dynamic model that predicts the reactor yields and the unit dynamics is becoming a crucial tool in determining and achieving the optimum operating conditions. This includes determining potential bottlenecks in the design and “what-if” scenarios evaluation.
