Book Description
Simultaneous Mass Transfer and Chemical Reactions in Engineering Science A comprehensive look at the basic science of diffusional process and mass transfer Mass transfer as a principle is an essential part of numerous unit operations in biomolecular, chemical, and process engineering; crystallization, distillation, and membrane separation processes, for example, use this important method. Given this significance – particularly in engineering design where these processes occur – understanding the design and analysis of such unit operations must begin with a basic understanding of how simultaneous mass transfer and the chemical reactions that influence these occurrences. It is also vital to be aware of the most up-to-date technologies for analyzing and predicting the phenomena. Given the significance of this process, Simultaneous Mass Transfer and Chemical Reactions in Engineering Science is an important resource as it introduces the reader to the complex subject of simultaneous mass transfer with biochemical and chemical reactions and gives them the tools to develop an applicable design. Analyzing the systems of simultaneous mass transfer and reactions is at the core of this book, as all known design approaches are carefully examined and compared. The volume also provides the reader with a working knowledge of the latest technologies – with a special focus on the open-sourced computer programming language R – and how these tools are an essential resource in quantitative assessment in analysis models. Simultaneous Mass Transfer and Chemical Reactions in Engineering Science provides a working knowledge of the latest information on simultaneous mass transfer and reactions by focusing on the analysis of this process, as well as discussing the existence and distinctive quality of the solutions to the Simultaneous Mass Transfer and Chemical Reactions in Engineering Science readers will also find: A theoretical basis of each design model that is carefully stated, compared, and assessed Carefully developed and established Existence and Uniqueness Theorems for a general design model Comprehensive coverage of how the programming language R may be used to analyze models Numerous examples and case studies that provide a working knowledge of simultaneous mass transfer and reactions Simultaneous Mass Transfer and Chemical Reactions in Engineering Science is a useful reference for students in chemical engineering, biotechnology, or chemistry, as well as professional process and chemical engineers.

Book Description
The surface renewal rate from Danckwerts' theory and the effective interfacial area between gas and liquid per unit packing volume in a packed absorption tower were evaluated for the absorption of carbon dioxide into carbonate/bicarbonate buffer solution accompanied by a pseudo-first order chemical reaction. The rate of chemical reaction in the liquid phase was controlled by varying the buffer ratios. A small absorption tower was constructed, which had a packing section, 30 cm high with 10.2 cm inside diameter. Two kinds of packing, 1/2-inch Rasehig ring for one part of the experiment and 1/2 inch Ben saddle for the other part of the experiment, were used in the investigation. Sodium carbonate/bicarbonate buffer solutions, with buffer ratios varying from 0.4 to 3.0, were used. Glycerine-water solutions were also used to investigate the effect of density and viscosity on the physical absorption of carbon dioxide; the content of glycerine varied from 0 to 40 % wt. Pure carbon dioxide was used to eliminate the gas side resistance in the mass transfer operation. The results of this investigation suggested the following conclusions: The surface renewal rate, s, and the effective interfacial area per unit packing volume, a, for each packing can be expressed as functions of Reynolds Number of the liquid flow. The comparison of values from this study with those of Danckwerts showed discrepancies; these discrepancies could be due to different flow patterns, packing densities, and the apparently more uniform distribution of liquid over the packing. The mass transfer coefficient for physical absorption into glycerine solution was expressed as a function of Reynolds number and Schmidt number. The mass transfer coefficient calculated from Danckwerts' model equation, kL*a = [Ds divided by a*] for absorption of carbon dioxide into water seemed to be larger than those measured in this experiment.

Book Description
This book is a comprehensive collection of chemical engineering terms in a single volume. The book is a useful reference material for the people both at the schools and the industry. Our experience of teaching and research over the years has made us to realize a must book of this kind. Better understanding of the terms helps in better understanding the relevant literature and in communicating with more assurance and less use of words. The book is easy to use as the terms are written in an alphabetical order. Where a term deserves more elaboration, a rather detailed description is provided. The book also contains a number of labeled diagrams which are extremely helpful in comprehending some important terms.

Book Description
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
