"Slurry bubble column reactors are intensively used as a multiphase reactor in the chemical, biochemical, and petrochemical industries for carrying out reactions and mass transfer operations in which a gas, made up of one or several reactive components, comes into contact or reacts with a liquid. This new volume, Hydrodynamics and Mass Transfer in Downflow Slurry Bubble Columns, describes the hydrodynamics of three-phase gas-liquid-solid flow in a downflow slurry bubble column. The efficiency of the downflow gas interacting system is characterized by the self-entrainment of secondary gas. The book covers the gas entrainment phenomena, gas holdup characteristics, pressure drop, gas-liquid mixing characteristics, bubble size distribution, interfacial phenomena, and the mass transfer phenomena in the downflow slurry system. Gas holdup has been analyzed by different models. A model for pressure drop in the system based on mechanical energy balance within the framework of dynamic interaction of the phases has been formulated and described.

This volume will be useful in chemical and biochemical industries and in industrial research and development sectors, as well as in advanced education courses in this area. The book will be helpful for further understanding the multiphase behavior in gas interacting multiphase systems for research and development. The hydrodynamic and mass transfer characteristics discussed will be useful in the design and installation of the modified slurry bubble column in industry for specific applications. Content: Gas distribution -- Gas hold-up characteristics -- Frictional pressure drop -- Bubble size distribution -- Dispersion phenomena -- Mass transfer phenomena.
