Available in PDF, EPUB and Kindle. Book excerpt: This advanced textbook covering the fundamentals and industry applications of process intensification (PI) discusses both the theoretical and conceptual basis of the discipline. Since interdisciplinarity is a key feature of PI, the material contained in the book reaches far beyond the classical area of chemical engineering. Developments in other relevant disciplines, such as chemistry, catalysis, energy technology, applied physics, electronics and materials science, are extensively described and discussed, while maintaining a chemical engineering perspective. Divided into three major parts, the first introduces the PI principles in detail and illustrates them using practical examples. The second part is entirely devoted to fundamental approaches of PI in four domains: spatial, thermodynamic, functional and temporal. The third and final part explores the methodology for applying fundamental PI approaches in practice. As well as detailing technologies, the book focuses on safety, energy and environmental issues, giving guidance on how to incorporate PI in plant design and operation -- safely, efficiently and effectively.

This book was released on 2014-01 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas-liquid-solid (catalysts) reactive systems encountered in trickle bed reactors are common in chemical engineering related cocurrent gas and liquid downflow systems. Among these processes relying on trickle beds, hydrodynamics of foaming systems are less prominently explored subject despite the formation of foaming is very often in the petroleum industries. This study's aim was to demonstrate experimentally the effects of liquid and gas flow velocities, and liquid surface tension for key phenomenon like regime transition change, two-phase pressure drop, dynamic liquid hold-up and liquid axial dispersion. More than 240 experimental points for the trickle flow (GCF) and foaming pulsing flow (PF/FPF) regime were obtained for present study, revealed significant evaluations for sustainable process design especially for industrial applications.

Available in PDF, EPUB and Kindle. Book excerpt: The design of chemical reactors and their safety are as critical to the success of a chemical process as the actual chemistry taking place within the reactor. This book provides a comprehensive overview of the practical aspects of multiphase reactor design and operation with an emphasis on safety and clean technology. It considers not only standard operation conditions, but also the problems of runaway reaction conditions and protection against ensuing over-pressure. Hydrodynamics of Multiphase Reactors addresses both practical and theoretical aspects of this topic. Initial chapters discuss various different types of gas/liquid reactors from a practical viewpoint, and later chapters focus on the modelling of multiphase systems and computational methods for reactor design and problem solving. The material is written by experts in their specific fields and will include chapters on the following topics: Multiphase flow, Bubble columns, Sparged stirred vessels, Macroscale modelling, Microscale modelling, Runaway conditions, Behaviour of vessel contents, Choked flow, Measurement techniques.

This book was released on 2019 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The impacts of the packing characteristics on the hydrodynamics od a trickle bed reactor (TBR) have been investigated using advanced measurements techniques of Gamma-ray densitometry (GRD) and Optical fiber probe and conventional measurement techniques of high-frequency differential pressure transducer and load cell. Two different reactor sizes of bench and pilot plant scale were used. Bench-scale TBR carried out the experiments to assess phase distribution and catalyst utilization with 1.18 cm inside diameter and 72 cm length at ambient pressure and temperature. The mixture of catalyst and fine particles displayed considerable improvements in the phase distribution, liquid holdup profile, and catalyst utilization efficiency. In the pilot plant scale reactor, the catalyst shape showed a significant impact on the hydrodynamics, pressure drop, local gas and liquid velocities, and flow regime transition. The currently used trilobe and quadrilobe in hydrotreating processes showed lower pressure drop, increased liquid holdup, enhanced local gas and liquid saturation and velocities, and lower flow regime transition compared with spherical and cylindrical shapes of catalysts. Meanwhile, mechanistic model named slit model predicted the pressure drop and liquid holdup better than selected correlations where equivalent diameter is used and the bed characteristic is quantitated properly by measured Ergun constants"--Abstract, page iv.

Available in PDF, EPUB and Kindle. Book excerpt: In this study we develop the computational and experimental tools to assist us in performance evaluation of trickle bed reactors (TBRs). The study focuses on experimental characterization of the flow distribution, and development of computational fluid dynamics (CFD) model of trickle flow. The experimental study has been performed to examine the quality of liquid phase distribution in a high pressure system. The results were provided in terms of distribution of the effluent liquid fluxes and cross-sectional liquid holdups. Their individual trends, but also their relation with respect to operating conditions was examined. Characterization of bed porosity distribution has been performed and used as the input to the computational model. The experimental study of the dependence of the extent of hysteresis on operating parameters in a high pressure TBR was performed. The extent of hysteresis was found uniquely determined by the pressure drop in the Levec prewetting mode. This fact and developed CFD model were then used to deduce conditions leading to operation with negligible hysteresis effects. Three-dimensional Eulerian CFD model is developed. Phase interaction closures are based on the film flow model, principles of statistical hydrodynamics and relative permeability concept. Model has been assessed against experimental data for liquid holdup, wetting efficiency and pressure drop hysteresis. Hydrodynamic Eulerian CFD model is then used together with species balance to examine the TBR performance for gas and liquid reactant limited systems. For each case a closed form approach of coupling bed and particle scale solution within CFD framework was presented.
