Book excerpt: Mass transfer from single rising gas bubbles is generally studied by taking motion pictures of the rising bubbles and analyzing the film for the instantaneous mass transfer coefficient. In this study, a different approach was taken for the analysis of mass transfer. This analysis solved the simultaneous differential equations describing mass transfer by numerical techniques. The computer model developed is restricted to pure single gas bubbles in water, with diameters in the size range 0.01 ≤ diameter ≤ 0.30 cm. Given a bubble's initial diameter and height of water over the bubble, the model predicts the bubble's position and moles of gas present in the bubble at any other time. The bubble rise velocity was calculated by considering a force balance on a spherical bubble and used theoretical values of drag coefficients based on a sphere. Correlations presented by Hamerton and Garner, Frossling, and Weiner were used to solve for KL, the convective mass transfer coefficient. The time dependent behavior of KL, attributed to the accumulation of surface active agents at the rising bubble's interface, was accounted for by the development of a bubble age parameter, termed critical time. The differential equations were solved by a Runge-Kutta-Merson routine, and the model applied to a carbon dioxide-water system. The results were compared to data collected in the investigations of Deindoerfer, Garbarini, and Datta. The computer predictions, with the inclusion of the critical time parameter, corresponded closely to data presented by the three investigators. The model, without the critical time parameter, predicted mass transfer rates much higher than those presented in the three investigations. The model was extended to pure oxygen-water and air-water systems to aid in the modeling of gas dispersion equipment used in aeration ponds. Predictions indicate that the initial bubble diameter has a significant role on the overall mass transfer.

Book excerpt: This book introduces the fundamental principles of the mass transfer phenomenon and its diverse applications in process industry. It covers the full spectrum of techniques for chemical separations and extraction. Beginning with molecular diffusion in gases, liquids and solids within a single phase, the mechanism of inter-phase mass transfer is explained with the help of several theories. The separation operations are explained comprehensively in two distinct ways—stage-wise contact and continuous differential contact. The primary design requirements of gas–liquid equipment are discussed. The book provides a detailed discussion on all individual gas–liquid, liquid–liquid, solid–gas, and solid–liquid separation processes. The students are also exposed to the underlying principles of the membrane-based separation processes. The book is replete with real applications of separation processes and equipment. Problems are worked out in each chapter. Besides, problems with answers, short questions, multiple choice questions with answers are given at the end of each chapter. The text is intended for a course on mass transfer, transport and separation processes prescribed for the undergraduate and postgraduate students of chemical engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Chemical Reactor Design and Operation K. R. Westerterp, W. P. M. van Swaaij and A. A. C. M. Beenackers Chemical Reaction Engineering Laboratories, Twente University of Technology, Enschede, The Netherlands This is a comprehensive handbook on the design and operation of chemical reactors which are vital elements in every manufacturing process. The book offers an introduction to the modern literature and covers in depth the relevant theory of chemical reactors. The theory is illustrated by numerous worked examples typical to chemical reaction engineering practice in research, development, design and operation. The examples range from fine chemicals to large scale production and from water purification to metallurgical processes, commencing with simple homogenous model reactors and then moving to the complicated, multi-phase, heterogeneous reactors met with in reality. All the examples are based on the industrial experience of the authors. Much effort is dedicated to the behaviour of reactors in practice and to the capacity, yield and selectivity of the reactor. The book is thoroughly indexed and cross-referenced. This edition will be particularly useful to undergraduate and graduate students studying chemical reactors. Contents Fundamentals of chemical reactor calculations Model reactors: single reactions, isothermal single phase reactor calculations Model reactors: multiple reactions, isothermal single phase reactors Residence time distribution and mixing in continuous flow reactors Influence of micromixing on chemical reactions The role of the heat effect in model reactors Multi-phase reactors, single reactions Multi-phase reactors, multiple reactions Heat effects in multi-phase reactors The authors: The authors have accumulated a long experience both in fine chemicals and in the petrochemicals industry, in Europe as well as abroad. Currently they are jointly responsible for the research work in chemical reaction engineering and process development at Twente University. Several new reactor types and new processes have been developed at their institute and present research interests include gasification, fluidization and gas--liquid reactors, three-phase reactors, high-pressure technology in chemical reaction engineering, thermal behaviour of heterogeneous reactors and computer design and economic evaluation of reaction units and chemical plants.

Available in PDF, EPUB and Kindle. Book excerpt: This overview of diffusion and separation processes brings unsurpassed, engaging clarity to this complex topic. Diffusion is a key part of the undergraduate chemical engineering curriculum and at the core of understanding chemical purification and reaction engineering. This spontaneous mixing process is also central to our daily lives, with importance in phenomena as diverse as the dispersal of pollutants to digestion in the small intestine. For students, Diffusion goes from the basics of mass transfer and diffusion itself, with strong support through worked examples and a range of student questions. It also takes the reader right through to the cutting edge of our understanding, and the new examples in this third edition will appeal to professional scientists and engineers. Retaining the trademark enthusiastic style, the broad coverage now extends to biology and medicine.

This book was released on 1983 with total page 700 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of "mass transfer with chemical reaction" takes place whenever one phase is brought into contact with one or more other phases not in chemical equilibrium with it. This phenomenon has industrial, biological and physiological importance. In chemical process engineering, it is encountered in both separ ation processes and reaction engineering. In some cases, a chemical reaction may deliberately be employed for speeding up the rate of mass transfer and/or for increasing the capacity of the solvent; in other cases the multiphase reaction system is a part of the process with the specific aim of product formation. Finally, in some cases, for instance "distillation with chemical reaction," both objectives are involved. Although the subject is clearly a chemical engineering undertakin, it requires often a good understanding of other subjects, such as chemistry and fluid mechanics etc., leading to publications in diversified areas. On the other har.d, the subject has always been a major field and one of the most fruitful for chemical engineers."
