Mass transfer phenomena can now be observed in many fields of industry. In particular, separation processes, which make up the vast majority of industrial production procedures, are governed by the physics of mass transfer, and their design and optimization depends heavily on knowledge in this field. This didactic approach to the principles and modeling of mass transfer as it is needed in modern industrial processes is unique in combining a step-by-step introduction to all important fundamentals with the most recent applications. Based upon the renowned author's successful new modeling method as used for the O-18 process, the exemplary exercises included in the text are fact-proven, taken directly from existing chemical plants. From the contents: * Diffusion and Mass Transfer * Governing Equations of Mass Transfer * Mass Transfer in Laminar Boundary Layer along a Flat Plate * Heat and Mass Transfer in Laminar Flow inside a Circular Pipe * Motion, Heat and Mass Transfer of Particles * Mass Transfer of Drops and Bubbles * Turbulent Transport Phenomena * Evaporation and Condensation * Multi-Component Distillation Fascinating reading for chemists, graduate students, chemical and process engineers, as well as thermodynamics physicists.
