Book excerpt: Packed bed columns are largely employed for absorption, desorption, rectification and direct heat transfer processes in chemical and food industry, environmental protection and also processes in thermal power stations like water purification, flue gas heat utilization and SO2 removal. These Separation processes, are estimated to account for 40%-70% of capital and operating costs in process industry. Packed bed columns are widely employed in this area. Their usage also for direct heat transfer between gas and liquid, enlarge their importance. They are the best apparatuses, from thermodynamical point of view, for mass and heat transfer processes between gas and liquid phase. Their wide spreading is due to low capital investments and operating costs. Since 1995 there has not been published a specialised book in this area, and this is a period of quick development of packed columns. Packed Bed Columns reflects the state of this field including the author's experience on creating and investigating of new packings, column internals and industrial columns. - Considers the theories of mass transfer processes and shows how they help the construction of highly effective packings - Complete information about the performance characteristics of different modern types of highly effective packings - Considers the models for calculation and areas of their application

Book excerpt: Gas Treating: Absorption Theory and Practice provides an introduction to the treatment of natural gas, synthesis gas and flue gas, addressing why it is necessary and the challenges involved. The book concentrates in particular on the absorption–desorption process and mass transfer coupled with chemical reaction. Following a general introduction to gas treatment, the chemistry of CO2, H2S and amine systems is described, and selected topics from physical chemistry with relevance to gas treating are presented. Thereafter the absorption process is discussed in detail, column hardware is explained and the traditional mass transfer model mechanisms are presented together with mass transfer correlations. This is followed by the central point of the text in which mass transfer is combined with chemical reaction, highlighting the associated possibilities and problems. Experimental techniques, data analysis and modelling are covered, and the book concludes with a discussion on various process elements which are important in the absorption–desorption process, but are often neglected in its treatment. These include heat exchange, solution management, process flowsheet variations, choice of materials and degradation of absorbents. The text is rounded off with an overview of the current state of research in this field and a discussion of real-world applications. This book is a practical introduction to gas treating for practicing process engineers and chemical engineers working on purification technologies and gas treatment, in particular, those working on CO2 abatement processes, as well as post-graduate students in process engineering, chemical engineering and chemistry.

This book was released on 2017 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This thesis studies the mass transfer performance and presents a unified approach in process modeling of a randomly packed column useful for controlling industrial scale CO2 emissions. A case study was conducted on the carbon dioxide absorption with aqueous sodium hydroxide in the packed column. The case study conducted helped in evaluating the mass transfer by using the method of transfer units, which involves the estimation of the height of transfer unit, number of transfer units, and overall gas-phase mass transfer coefficients. The process model developed was an automatic online control and uses a feedback Proportional-Integral-Derivative (PID) Controller. Internal Model Control (IMC) and Ziegler-Nichols (Z-N) tuning methods were used to tune the PID controller based on the process dynamic model and model parameters obtained from the step tests. The overall gas-phase mass transfer coefficient (K Ga) values obtained from the experimental data are comparable to the published data in the literature.
Download or read book Absorption written by Roman Zarzycki and published by Pergamon. This book was released on 1993 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paperback. This book gives a practical account of the modern theory of calculation of absorbers for binary and multicomponent physical absorption and absorption with simultaneous chemical reaction. The book consists of two parts: the theory of absorption and the calculation of absorbers. Part I covers basic knowledge on diffusion and the theory of mass transfer in binary and multicomponent systems. Significant stress is laid on diffusion theory because this forms the basis for the absorption process. In the next chapters the fundamentals of simultaneous mass transfer and chemical reaction, the theory of the desorption of gases from liquids and the formulation of differential mass balances are discussed. Part II is devoted to the calculation of absorbers and the classification of absorbers. The chapters present calculation methods for the basic types of absorber with a detailed analysis of the calculation methods for packed, plate and bubble columns. The a

Available in PDF, EPUB and Kindle. Book excerpt: Process Intensification: Engineering for Efficiency, Sustainability and Flexibility is the first book to provide a practical working guide to understanding process intensification (PI) and developing successful PI solutions and applications in chemical process, civil, environmental, energy, pharmaceutical, biological, and biochemical systems. Process intensification is a chemical and process design approach that leads to substantially smaller, cleaner, safer, and more energy efficient process technology. It improves process flexibility, product quality, speed to market and inherent safety, with a reduced environmental footprint. This book represents a valuable resource for engineers working with leading-edge process technologies, and those involved research and development of chemical, process, environmental, pharmaceutical, and bioscience systems. - No other reference covers both the technology and application of PI, addressing fundamentals, industry applications, and including a development and implementation guide - Covers hot and high growth topics, including emission prevention, sustainable design, and pinch analysis - World-class authors: Colin Ramshaw pioneered PI at ICI and is widely credited as the father of the technology

Available in PDF, EPUB and Kindle. Book excerpt: In conjunction with the work on interfacial area and contact time, an investigation was carried out to study the factors affecting mass transfer coefficients in vapor-liquid contacting. Measurements of point efficiency on the distillation of a systems of acetone and water determined both the liquid and vapor mass transfer coefficients under various operating conditions. The study was conducted on a 4" diameter column using the same type of single-slotted 1.5" diameter cap employed in the previous work. The range of physical properties and operating variables included: vapor rate: G=5000 to 25,000 lbs./sq.ft.(hr.); liquid rate: L=500 to 3,600 lbs./sq.ft.(hr.) ; vapor Reynolds number: 6400 to 24,100; liquid Reynolds number: 35 to 800 ; vapor Schmidt number: 0.27 to 0.42; liquid Schmidt number: 50 to 330. Both vapor and liquid mass transfer coefficients were correlated as "jD" factors, with their respective Reynolds numbers. The equations developed were: [....]. In combination with the results on interfacial area and contact time, a generalized correlation for point efficiency data reported in the literature (30,53) and found it to be in excellent agreement. Based upon analysis of this and other studies reported in the literature (21,22) an explanation of the mechanisms involved in bubble plate mass transfer operations was presented. Since the efficiencies measured in this study were uniformly high, even in the absence of a froth zone, it was indicated that a substantial portion of the mass transfer occurring on a bubble cap plate takes place in the bubble formation region.
