Eliminating FCC Regenerator Afterburn
This presentation by Ray Fletcher is part one of a two-part presentation that explores how to extract key data from Barracuda Virtual Reactor simulation results.
Hydrodynamics of High Velocity Circulating Fluidized Bed Risers
In this research the solids flux measurements showed the risers having different shapes of radial profiles. The net solids flow direction at all radial locations was found to be upward for the conditions used in this study.
Ray Fletcher, FCC Technology Specialist at Johnson Matthey, describes some of the challenges faced when attempting to troubleshoot FCC regenerators and how Barracuda Virtual Reactor helps him to overcome those obstacles.
