Solid-Solid, Fluid-Solid, Fluid-Fluid Mixers, part of the Industrial Equipment for Chemical Engineering set, presents an in-depth study of a variety of aspects within the field of chemical engineering. This volume is both theoretical and practical, focusing on emulsions of one liquid into another, the dispersal of a divided solid into a liquid, and a gas into a liquid. The book includes examples of mixtures of two powders, the process of dissolution of a powder in a liquid, and the homogenization of a pasty product. The types of devices needed, the criterion for homogeneity, the expended mechanical power, the flow processed, and the time required for the operation are also discussed. The author provides methods needed for understanding the equipment used in applied thermodynamics in the hope of encouraging students and engineers to self build the programs they need. Chapters are complemented with appendices that provide additional information and associated references. Presents advanced study on the dispersion of a gas in a liquid and the dispersion of a liquid insoluble in another liquid (emulsification) Includes specific cases of dispersion and dissolution of powders Provides criteria for evaluating the homogeneity of a mixture

Liquid-Solid Separators, part of the Industrial Equipment for Chemical Engineering set, presents detailed information on the filtration parameters that are used to calculate and measure the properties of filters that separate a divided solid from a liquid. Well-known equations are used to describe the passing of a solution through a membrane, deducing the expression of membrane rejection for solutes. Biological membranes are used as examples, and their ionic flows and involvement in reactions within the membrane are discussed. The author also provides information on the methods needed for understanding the equipment used in applied thermodynamics in the hope of encouraging students and engineers to self build the programs they need. Chapters are complemented with appendices that provide additional information and associated references.

Fluid Transport: Pipes, part of the Industrial Equipment for Chemical Engineering set, provides a description and calculation of the essential equipment used for fluid transport. Gas-liquid flows are studied with regard to the nature of this type of flow, along with the pressure drop that they may trigger. Many numerical examples are offered, and the calculation of a fluid transport line is detailed. The vacuum technique and the behavior of non-Newtonian liquids is thoroughly presented, and the author also provides the methods needed for understanding the equipment used in applied thermodynamics to encourage students and engineers to self build the programs they need. Chapters are complemented with appendices that provide additional information and associated references. Contains practical applications of ejectors and thermo-compressors Establishes pipe diameter thickness Includes studies in general and other types of valves Presents process parameters and the calculation of a control Provides a theoretical study of control valves and gas pipelines

This book is a compilation of the engineering data on mixing, which have appeared in the major technical journals of chemical engineering and bioengineering since 1975. That year marked the beginning of a period of rapid advancement in the science and technology of mixing, with rather reliable results for both theoretical and experimental studies. In addition, some important earlier articles which have been, and still are being referred to, are included. Designs of both agitators and tanks still depend primarily on art and experience. In light of this it was felt that the data on mixing should be compiled and presented in a systematic manner to assist in design and analysis of agitated tanks, and to provide easier access to mixing data for various engineering activities. Although computer-aided searches of pertinent data bases can be of assistance to chemical engineers and bioengineers in their studies, they are sometimes time-consuming and often costly. Furthermore inadequate selection of key words can jeopardize the searches. This book offers an alternative method of surveying mixing data which interests readers. The first chapter presents a variety of results for the experimental measurements of flow patterns in stirred tanks. Most of the measurements were made by using modern Laser-Doppler techniques. This chapter is useful for the prediction of flow patterns in tanks with many different geometries, various types of agitators, and fluids of diverse physical and rheological properties, plus valuable data for the validation of results obtained by CFD simulations. Chapters 2 through 5 deal with data for traditional chemical engineering subjects and Chapter 6 summarizes a number of scale-up relations developed over the years for various systems. These include liquid, solid-liquid, liquid-liquid, gas-liquid, and solid-liquid-gas systems. Chapter 7 provides data related to multiphase processes, and most importantly, drop size and drop-size distributions and bubble-size distributions. These two subjects have not been treated systematically either in text books or in handbooks on stirred-tank mixing, although the results of both experimental and theoretical investigations have been reported on many occasions. Finally gas-inducing mechanically agitated systems are dealt with. The applications of this type of agitation system will become increasingly attractive from the standpoint of rationalization of stirred-tank operations as well as environmental protection.

This text allows instructors to teach a course on heat and mass transfer that will equip students with the pragmatic, applied skills required by the modern chemical industry. This new approach is a combined presentation of heat and mass transfer, maintaining mathematical rigor while keeping mathematical analysis to a minimum. This allows students to develop a strong conceptual understanding, and teaches them how to become proficient in engineering analysis of mass contactors and heat exchangers and the transport theory used as a basis for determining how critical coefficients depend upon physical properties and fluid motions. Students will first study the engineering analysis and design of equipment important in experiments and for the processing of material at the commercial scale. The second part of the book presents the fundamentals of transport phenomena relevant to these applications. A complete teaching package includes a comprehensive instructor's guide, exercises, case studies, and project assignments.

This long awaited second edition of a popular textbook has a simple and direct approach to the diversity and complexity of food processing. It explains the principles of operations and illustrates them by individual processes. The new edition has been enlarged to include sections on freezing, drying, psychrometry, and a completely new section on mechanical refrigeration. All the units have been converted to SI measure. Each chapter contains unworked examples to help the student gain a grasp of the subject, and although primarily intended for the student food technologist or process engineer, this book will also be useful to technical workers in the food industry
