Description
A comprehensive and up-to-date look at fluidization processes
Fluidization Processes: Design and Operation delivers a thorough, practical guide to the design and operation of gas-solid fluidized-bed systems. It grounds readers in the critical concepts that underpin industrial performance, including jets, bubbles, entrainment, heat transfer, particle cohesion, attrition, and fluidization regimes.
With a strong emphasis on application, the book explains key design calculations and modeling approaches used in industry. It also provides scale-up methodologies and essential design considerations, along with discussions of bubbling and turbulent fluidized-bed hydrodynamics, circulating fluidized bed (CFB) riser hydrodynamics, and the major components of fluidized-bed units.
Readers will also find:
- Thorough introductions to core fluidization concepts and particle properties, including Geldart particle classifications
- Comprehensive coverage of fluidization regimes, including particle elutriation and entrainment
- Practical discussions of design and operation, including distributors, attrition and erosion
- Complete treatments of cyclone design and operation, diplegs and standpipes, and pressure-loop calculations
Perfect for chemical engineers and process engineers, Fluidization Processes: Design and Operation will also benefit environmental engineers, catalytic chemists, materials scientists, and industrial chemists.
