Industrial Applications of Fluidized Beds and Fluidization of Fine Particles (Invited Talk)

Multiphase flow and fluidization of fine particles has a wide application in the industry. The industrial fluidized bed process ranges from simple applications like drying, cooling, pneumatic transport of powders, etc. to more complex chemical reactors such as FCC for oil cracking, CVD coating of solids in a fluidized bed, combustion or gasification of coal or biomass, etc. The list of the fluidized bed application is long, along with the challenges the industry is facing with fluidization of such fine powders. Understanding the physical properties and flow characteristic of particles is key when designing and operating such fluidized bed units. In this session, the selected papers will mainly address the approach and tools used to understand the particle flow behavior in an industrial process and also the steps taken to address and troubleshoot the industrial scale problems.
