Tests were conducted in 0.6-m and 0.9-m-diameter units to determine the effect of imposed solids flux and system pressure on gas bypassing in deep beds of FCC catalyst particles.
CPFD Software and Anellotech, Inc. (Pearl River, NY) announce their software licensing agreement. Anellotech aims to use CPFD’s Barracuda Virtual Reactor® as part of the design process for a commercial-scale fluidized bed reactor for its cutting-edge Plas-TCat™ process.
In this paper, computational modeling of fluidized beds is used to predict the operation of biomass gasifiers after extensive validation with experimental data, and hydrodynamic results from the simulations were compared with X-ray flow visualization computed tomography studies of a similar bed.
This paper presents new capabilities and proof-testing of a collisional model previously presented in O’Rourke, Zhao, and Snider (2009) applied to liquid injection into a dense-phase fluidized bed.
CPFD Software’s joint entry with Encina Development Group, entitled “Converting Plastic Waste into Circular Chemicals” is a finalist for the 2022 Process Automation and Digitalisation Award as well as the 2022 Sustainability Award for demonstrating excellence in chemical, biochemical and process engineering.
Researchers from CPFD and Cristal Global present a solution of ozone decomposition in a bubbling bed using the CPFD numerical scheme. Results compared well with the experimental data reported by Fryer and Potter (1976).
This work presents a new methodology, based on the maximum entropy method, to obtain bubble characteristics in fluidized beds.
CPFD is sponsoring the Particle Technology Forum (PTF) Student Poster Awards by continuing its longstanding support of the American Institute of Chemical Engineers (AIChE) Annual meeting. Additionally, Peter Blaser, VP of Operations will be co-chairing the Fluidization: Modeling session on November 14’22 at Phoenix Convention Center.
A new model is presented by O’Rourke, Zhao, and Snider for numerical simulations of collisional transfer of mass, momentum and energy in gas/liquid/solid fluidized beds.
Most investigations of fluidization parameters take place at ambi- ent temperature and pressure. Yet, nearly all processes operate at elevated temperature, and many at elevated pressure.
