Some Industrial Fluid-Bed Applications

The fluidised bed is only one of the many reactors employed in industry for gas-solid reactions, as reported by Kunii and Levenspiel.25 Whenever a chemical reaction employing a particulate solid as a reactant or as a catalyst requires reliable temperature control, a fluidised bed reactor is often the choice for ensuring nearly isothermal conditions by a suitable selection of the operating conditions. The use of gas-solid fluidised beds 

Heat and/or mass transfer between gas/ particle Solids drying Absorption of solvents Food freezing 

Heat and mass transfer between particle/ particle or particle/surface Coating of pharmaceutical tablets Granulation Mixing of solids Plastic coating of surfaces 

Heat transfer between bed/surface Heat treatment of glasses, rubber, textile fibres 

Qas/gas reaction in which solid acts as catalyst Oil cracking Manufacture of Acrylonitrile Polyethylene
