We Cherish All Interactions
Fluidized bed reactors are widely used in the petrochemical (catalytic cracking) and chemical process industries (phthalic and maleic anhydride, oxychlorination of ethylene, .
A fluidized bed reburning system is illustrated in Fig. 6.6. Ender's fluidized bed lime calciner is a two-stage fluidized bed reactor; the upper compartment is the dryer and the lower compartment is the calciner (). Lime mud is pumped into the drying stage where it is dried with the hot gases which flow through the bed .
This book puts forward the concept of the Diameter-Transformed Fluidized Bed . Covers fundamental research as well as process development and practice in petrochemical industry . for Chinese vehicles. Currently, 84% of FCC units in Sinopec facilities utilise the diameter-transformed fluidised bed reactor.
An integrated fluidized bed reactor (FBR) has been employed as the treatment for petrochemical industry wastewaters with high organic matter and aromatic compounds, under anaerobic and aerobic conditions. The system was operated at hydraulic residence time (HRT) of 2.7 and 2.2 h in the anaerobic and aerobic reactor, respectively.
Additionally, fluidized beds are used to produce other products and chemicals downstream of the FCCU, such as polyethylene, polypropylene, and acrylonitrile, to name a few. Since 2006, the team at CPFD has utilized our Barracuda Virtual Reactor® software to optimize the design and operation of fluidized processes for the Oil, Gas and .
One of the first United States fluidized bed reactors used in the petroleum industry was the Catalytic Cracking Unit, created in Baton Rouge, LA in 1942 by the Standard Oil Company of New Jersey (now ExxonMobil). This FBR and the many to follow were developed for the oil and petrochemical industries.
Current Applications for Fluidized Bed Reactors FBRs are everywhere in the Process Industries. They find broad use in the petroleum and petrochemical industries, as well as numerous chemical industries.
The Industrial Thermochemical Conversion (ITC) Group provides expertise in thermochemical conversion processes that involve multiphase particulate flows and fluidized bed systems. The group provides novel designs, problem solving expertise, system optimization, and integration strategies for a variety of industrial processes and clients.
In the past thirty years, although petrochemical enterprises all over the world have invested heavily in developing reactor technology, the petroleum and chemical industries still mainly used the slurry bed, fixed bed, moving bed, and fluidized bed reactors. Upgrading of the petrochemical industry technology must rely on the integration and .
A fluidized-bed reactor was designed and constructed for practical demonstration of the fluidization of solid particles at different fluid flow rates. The bed of this reactor was sand particles of .
