This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Slurry bubble columns and gas-solid fluidized bed reactors are some of the most commonly used industrial processes. Considerable interests have been recognized in the field of physical, chemical, petrochemical, electrochemical, and biochemical operations (Fan, 1989). In these reactor systems, large axial dispersion of phases and high flow patterns can be achieved by the excellent macromixing characteristics. It also provides excellent heat and mass transfer without the aid of external mechanisms and relatively easy operation. Despite the advantages of operations, the transport behavior in these systems is very complex and a comprehensive knowledge of the hydrodynamics, heat and mass transfer and mixing are required for successful application of these systems. Some aspects of the fundamental characteristics of evaporative liquid jets in gas-liquid-solid flows are studied and some pertinent literature is reviewed. It is found that the injection of an evaporative liquid jet decreases the minimum fluidization velocity at a high pressure due to the additional gas flow generated from liquid evaporation. Fluidizing gas velocities have no significant effect on the jet penetration length in a dense phase fluidized bed while it reduces the radial dispersed distance of the evaporative liquid. The tomographic images of liquid nitrogen injection in a dense phase fluidized bed indicate a distribution of reduced bubble sizes compared to a dry bed. The hydrodynamics, gas-liquid mass transfer properties and liquid entrainment phenomena in a high pressure and high temperature bubble column is investigated. Effects of pressure on hydrodynamics and mass transfer properties are mainly through the change in gas and liquid physical properties, which in turn changes the bubble dynamics that govern the transport phenomena. Experimental results show that liquid velocities have a direct influence on kl while other factors have a dominant effect on the interfacial area over kl. Liquid entrainment in bubble columns is controlled by the droplet formation during bubble bursting at interface. Effect of pressure on liquid entrainment is to due to the higher drag force exerted on the liquid droplet with higher gas density and the formation of smaller droplet by the smaller bubbles at high pressure.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive mechanistic interpretation of the transport phenomena involved in various basic modes of gas-liquid-solid fluidization. These modes include, for example, those for three-phase fluidized beds, slurry columns, turbulent contact absorbers, and three-phase fluidized beds, slurry columns, turbulent contact absorbers, and three-phase transport. It summarizes the empirical correlations useful for predicting transport properties for each mode of of operation.Gas-Liquid-Solid Fluidization Engineering provides a comprehensive account of the state-of-the-art applications of the three-phase fluidization systems that are important in both small-and large-scale operations. These applications include fermentation,biological wastewater treatment, flue gas desulfurization and particulates removal, and resid hydrotreating. This book highlights the industrial implications of these applications. In addition, it discusses information gaps and future directions forresearch in this field.

This book was released on 1989 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transport Processes in Engineering is a new multidisciplinary series of books intended to provide, in an integrated fashion, authoritative and timely coverage of selected topics in fluid mechanics, heat and mass transfer. The series will publish edited works on coherent themes of current and potential application as well as monographs and advanced reference works for researchers, advanced students, practicing engineers and applied scientists. This first volume covers transport processes in several major areas of application of fluidized-bed contactors. It does not attempt to achieve an exhaustive treatment of its subject, rather it includes areas which constitute important non-conventional applications of fluidized-bed systems, offering something new even to those already well-versed in fluidization technology. The book will be of interest to engineers and technologists in the chemical, agricultural, food, mechanical, metallurgical, mineral processing and energy engineering areas with an interest in current or potential applications involving conventional and/or modified fluidized beds.

It has a wide range of applications in chemical & process engineering. The gas hold- Up (Eg) & the volumetric liquid phase mass transfer coefficient (KLa) were studied experimentally in the present work by using ethanol - water mixture as liquid phase & air as a gas phase. The study was developed to express the effects of the process variables on Eg & KLg the exponential work was designed for this purpose in the following experimental range: 1.Weight percent of ethanol in water (0- 0.8) Wt%. 2.Superficial gas velocity of air (0.01-0.11) m/s. 3.Operation temperature (26-27) C. 4.Operating pressure (1x 105 - 6x105) N/m2"

Available in PDF, EPUB and Kindle. Book excerpt: Two-phase and three-phase fluidized beds have been applied successfully to many industrial processes such as in the H-oil process for hydrogenation and hydrodesulfurization of residual oil, the H-coal process for coal liquefaction, Fischer-Tropsch process, and the bio-oxidation process for wastewater treatment. A semi-fluidized bed has the advantages of both the packed and the fluidized beds as it can partly over come the disadvantages of a fluidized bed, namely back-mixing of solids, attrition of particles and erosion of surfaces, and those of a packed bed, such as non-uniformity in bed temperatures, segregation of solids and channeling. Semi-fluidized beds have been applied successfully to many industrial processes (physical, chemical and biochemical)such as in the filtration, adsorption, catalytic reactions, heavy metal removal and recovery, coal pyrolysis, bio-oxidation, ethanol fermentation, granule tablet manufacturing etc.
