Preface to the Second Edition NEW TO THIS EDITION "Time and tide wait for no man" and most certainly not for engineering textbooks. The seven years since publication of the first edition of "Separation Process Principles" have witnessed: (1) advances in the fundamentals of mass, heat, and momentum transport and wide availability of computer programs to facilitate the application of complex transport mathematical models; (2) changes in the practice of chemical engineering design; and (3) restructuring of the chemical engineering curriculum. In response to what we have noted and what has been pointed out in strong reviews solicited by the publishers, we have included the following revisions and additions to this second edition: A new section on dimensions and units to facilitate the use of the SI, AE, and CGS systems, which permeate applications to separation processes. The addition to each chapter of a list of instructional objectives. Increased emphasis on the many ways used to express the composition of chemical mixtures. New material on the thermodynamics of difficult mixtures, including electrolytes, polymer solutions, and mixtures of light gases and polar organic compounds. Tables of typical diffusivity values. Table of formulae and meanings of dimensionless groups. A subsection on the recent theoretical analogy of Churchill and Zajic. New sections on hybrid systems and membrane cascades. Discussions of the fourth generation of random packings and high-capacity trays. A brief discussion of the rate-based multicell model. New section on optimal control as a third mode of operation for batch distillation. New discussion on concentration polarization and fouling. New sections on ultrafiltration and microfiltration. New subsection on Continuous, Countercurrent Adsorption Systems. Revision of the subsection on the McCabe-Thiele Method for Bulk Separation by adsorption. New subsection on Simulated (and True) Moving Bed Systems for Adsorption. The following three chapters were not in the first edition of the book, but were available in hard copy, as supplemental chapters, to instructors. They are now included in the second edition: Chapter 16 on Leaching and Washing, with an added subsection on the espresso machine. Chapter 17 on Crystallization, Desublimation, and Evaporation. Chapter 18 on Drying of Solids, including Psychrometry. In the first edition, each topic was illustrated by at least one detailed example and was accompanied by at least three homework exercises. This continues to be true for most of the added topics and chapters. There are now 214 examples and 649 homework exercises. In addition, 839 references are cited.
Process Technology provides a general overview about chemical and biochemical process technology. It focuses on the structure and development of production processes, main technological operations and the important aspects of process economics. The theoretical foundations in each chapter are supplemented by case studies and examples in a clear and instructive manner to illustrate the practical aspects. The author highlights operating principles, reasons for application and available industrial equipment of technological operations. Aim is to facilitate those without a process technology background in multi-disciplinary cooperation with (bio-) chemical engineers by providing an overview of this exciting field. The textbook is organized into seven distinct parts: Structure of the chemical industry and (bio-) chemical processes (Bio-) Chemical reaction engineering Molecular separations (distillation, extraction, absorption, adsorption) Mechanical separations (filtration, sedimentation, membranes) Particle and final product manufacturing Development, scale-up, design and safety of processes Major industrial process descriptions
The rising trend towards the operation of packed towers in separation processes was initiated after the energy crisis in the seventies. This book is the first of its kind which treats all the important theoretical and practical aspects for the calculation, design and operation of these packed towers. The main applications of packed towers are in the separation of gas-liquid or vapour-liquid systems. This book considers all features of packed towers for industrial separation plants that can be used in process and environmental technology. It includes a comprehensive treatment of packed-bed technology and the advantages of packed towers, such as the application of improved methods for energy saving purposes, environmental protection measures and the revamping of existing plants, are clearly outlined. The methods presented are based on sound physical and mathematical modelling, the validity of which have been confirmed by numerous experimental investigations performed in laboratories and pilot plants and then scaled up to meet practical, industrial requirements.
Distillation & Hydrocarbon Processing Practices is a practical reference guide to the design and operations of hydrocarbon processing plants (refineries, petrochemical plants, and gas processing plants). Ashis Nag illustrates advanced practices in distillation with examples of process simulation and basic principles. Nag’s extensive knowledge and more than 35 years of experience as an engineer supply the practical examples and design guidelines contained in this text. Its many case studies will assist engineering students as well as practicing engineers in understanding the inner workings at these complex facilities.
