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.
Incorporating Oxygen Uncoupling Kinetics into Computational Fluid Dynamic Simulations of a Chemical Looping System
In this study by the University of Utah, Barracuda simulations for a chemical looping with oxygen uncoupling system compared well with literature and data.
Dynamic Behavior of Fluidized Bed Reactors for Gas Phase LLDPE Polymerization
In this work researchers from SABIC and CPFD investigate the dynamic behavior of a commercial fluidized bed LLDPE reactor and compare with plant data.
Experimental Validation of CFD Hydrodynamic Models for Catalytic Fast Pyrolysis (CFP)
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.
CPFD Joins Altair Partner Alliance
CPFD Software is thrilled to announce that we have joined the Altair Partner Alliance (APA). APA-enabled Altair customers can now enjoy instant-access to Barracuda Virtual Reactor, expanding Altair’s modeling capabilities and directly complementing their EDEM discrete element method software.
CFD Studies on Biomass Gasification in a Pilot-Scale Dual Fluidized-Bed System
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.
CPFD Modeling and Experimental Validation of Gas–Solid Flow in a Down Flow Reactor
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.
CPFD Releases Barracuda Virtual Reactor 23.0
CPFD announces the release of Barracuda Virtual Reactor® 23.0 which provides users with more control over drag models and material properties with more enhanced features.
Particle Attrition: Mechanisms and Methods to Determine Attrition Indices
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.
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.
