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 entrainmentPractical discussions of design and operation, including distributors, attrition and erosionComplete treatments of cyclone design and operation, diplegs and standpipes, and pressure-loop calculationsPerfect for chemical engineers and process engineers, Fluidization Processes: Design and Operation will also benefit environmental engineers, catalytic chemists, materials scientists, and industrial chemists.
