Identifying the Root Cause of Afterburn in Fluidized Catalytic Crackers
This paper, first presented at the 2016 AFPM Annual Meeting, provides an overview of general and localized afterburn, and discusses techniques for effective troubleshooting.

In this study by the University of Utah, Barracuda simulations for a chemical looping with oxygen uncoupling system compared well with literature and data.
In this work researchers from SABIC and CPFD investigate the dynamic behavior of a commercial fluidized bed LLDPE reactor and compare with plant data.
Researchers at KiOR LLC working with CPFD Software staff use Barracuda Virtual Reactor to develop a Catalytic Fast Pyrolysis (CFP) technology that emulates the FCC process.
A model using the MP-PIC method was developed to simulate a pilot-scale dual fluidized-bed biomass gasification system and was validated by experimental results; it was then used to investigate the impact of various changes on the producer gas composition.
In this paper, a hybrid model of a gas-solid fluidized bed unit is developed using Barracuda Virtual Reactor and then is validated by experimental data.
Particle attrition can be a major issue in using catalyst particles in fluidized beds and circulating fluidized beds. Particles tend to break down via two mechanisms – abrasion and fragmentation.
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.
This publication demonstrates that pressure fluctuations and local bubble void fraction can diagnose gas bypassing
The hydrodynamics of FCC particles in a bubbling fluidized bed are predicted by both Barracuda Virtual Reactor and by a CFD model, and their results were compared.
