Hydrodynamics and Mass Transfer in Downflow Slurry Bubble Columns

Hydrodynamics and Mass Transfer in Downflow Slurry Bubble Columns PDF Author: Subrata Kumar Majumder
Publisher: CRC Press
ISBN: 1351249843
Category : Science
Languages : en
Pages : 168

Book Description
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 volume 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, gasliquid mixing characteristics, bubble size distribution, interfacial phenomena, and the mass transfer phenomena in the downflow slurry system. 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.

Spouted and Spout-Fluid Beds

Spouted and Spout-Fluid Beds PDF Author: Norman Epstein
Publisher: Cambridge University Press
ISBN: 1139492721
Category : Technology & Engineering
Languages : en
Pages : 363

Book Description
Since the pioneering text by Mathur and Epstein over 35 years ago, much of the work on this subject has been extended or superseded, producing an enormous body of scattered literature. This edited volume unifies the subject, pulling material together and underpinning it with fundamental theory to produce the only complete, up-to-date reference on all major areas of spouted bed research and practice. With contributions from internationally renowned research groups, this book guides the reader through new developments, insights and models. The hydrodynamic and reactor models of spouted and spout-fluid beds are examined, as well as such topics as particle segregation, heat and mass transfer, mixing and scale-up. Later chapters focus on drying, particle-coating and energy-related applications based on spouted and spout-fluid beds. This is a valuable resource for chemical and mechanical engineers in research and industry.

Book Description
Fluidized beds have gained prominence in many process in dustries (including chemicals, petroleum, metallurgy, food and pharmaceuticals) as a means of bringing particulate solids into contact with gases and/or liquids. Many fluidized bed operations are physical in nature (e.g. drying, coating, classification, granulation, and rapid heat transfer as in quenching or annealing). Other operations involve chemical reactions including the cata lytic cracking of hydrocarbons, the manufacture of acry10nitrite and phthalic anhydride, the roasting of metallurgical ores, and the regeneration of spent catalysts. In recent years fluidized beds have been of special interest because of their potential as the central component in new processes for utilizing coal as a source of energy, notably in coal combustion and gasification processes. The fluidized bed offers a number of advantages over most other methods of contacting, in particular high rates of heat transfer, temperature uniformity and solids mobility. Among the disadvantages are particle losses by entrainment, attrition of solids, limited reactor efficiency due to gas bypassing and gas and solids backmixing, and difficulties in design and scale-up due to the complexity of fluidized beds. The International Fluidization Conference held in Henniker, New Hampshire, U.S.A. from 3-8 August 1980 was the fifth inter national congress devoted to the entire field of fluidization.
