- this video shows the model of a full-scale fluidized catalytic cracking (FCC) regenerator using the Eulerian-Lagrangian CPFD method in Barracuda VR. This is a simulation of an actual operating unit in at a U.S. refinery. This is the first simulation of its kind known to exist for an entire FCC regenerator with the coke-burning chemistry included. The purpose of the simulation was to determine root causes for afterburn in the unit (undesirable temperature rise between the top of the bed and the discharge), which has been present in unit for over 70 year and has never before successfully been addressed.
