Calculating PSD at a Flux Plane using flux2psd
In Barracuda simulations, the particle size distribution (PSD) of particles crossing a flux plane is often of interest. This post shows how to calculate the PSD when the “Bin by…
CO2 Capture Using Chemical Looping Combustion from a Biomass-Derived Syngas Feedstock: Simulation of a Riser–Downer Scaled-up Unit
This simulation study the University of Western Ontario demonstrates the scalability of chemical looping combustion (CLC) to achieve efficient capture of biomass-derived CO2.
Calculating PSD at a Flux Plane using Flux2PSD.tcl
In Barracuda simulations, the particle size distribution (PSD) of particles crossing a flux plane is often of interest. This post shows how to calculate the PSD when the “Subdivide by…
Improved Distribution of Spent Catalyst
Application of a newly designed spent catalyst distributor improves spent catalyst distribution, coke combustion and bed temperatures in the FCC in this article by Raj Singh, Paul Marchant and Steve Shimoda of TechnipFMC Process Technology.
Analyzing Heat Transfer through Thermal Wall BCs
Thermal Wall BCs in Barracuda allow heat transfer to and from the system, depending on the relative temperatures of the walls and fluid in computational cells. This post discusses how…
TRI Scales Up Novel Waste-to-Fuels Technology
TRI’s technology was deployed at Fulcrum BioEnergy’s Sierra BioFuels Plant, which converts ~175,000 tons of landfill waste into renewable, transportation fuels with 80% lower carbon emissions.
MULTIFRAME.tcl
Combining multiple views of simulation results into a single animation is a commonly used technique during post-processing of Barracuda results. The MULTIFRAME.tcl script was written to make this task easier,…
Improving Circulating Fluidized Bed Dehydrogenation Technology through Optimization of Fluidization
This publication by SABIC provides insights into improving fluidization behavior by way of a systematic approach to determine the underlying root causes of issues in a commercial dehydrogenation reactor.
Installing Extra Packages for Cygwin
The default Cygwin installation included with Barracuda VR includes a minimal set of packages to support the operation of GMV on Windows. For some tasks, it is necessary to install…
Avoid Nasty Surprises
Surprises are not always a good thing, especially during plant turnarounds. This article, from the September 2019 issue of Hydrocarbon Engineering, discusses how simulations can be a critical turnaround risk reduction tool.
