Mass Transfer Operations

This updated edition of Mass Transfer Operations is designed for students, engineers, and anyone looking to understand how separation processes work in chemical engineering. Whether used in a classroom or for self-study, the book offers clear explanations and practical design methods for a wide range of mass-transfer equipment and processes. Mass transfer operations—such as distillation, absorption, extraction, and drying—are key to chemical production, pollution control, and environmental protection. This book explains both the theory and real-world applications of these processes in a way that is easy to follow. The new edition includes updated explanations, modern design data, and improved readability. New topics such as surface-stretch theory, transpiration cooling, advanced tray towers, and heatless adsorption systems have been added. You will also find complete design methods for equipment like mixer-settlers, sparged vessels, and adiabatic packed towers. One major improvement is the switch to SI units throughout the book, with almost all equations now usable in any consistent unit system. Helpful conversion tables are included to make the transition easier. With new worked examples and over 1,000 equations, this edition is a valuable tool for learning and applying mass-transfer principles in real situations. The book is written to help you gain both a solid foundation and the confidence to solve practical problems in chemical and environmental engineering. Whether you are studying for a course or working in the field, this book offers the knowledge and tools you need to understand and design effective separation processes.
