Practical insights from the leading professionals in the field While process objectives are critical to the successful manufacturing of a product. if the mixing scale-up fails to produce the required results, the costs of manufacturing can increase significantly. Although there are several industrial operations in which mixing requirements are readily scaled up from established correlations, many operations require a more thorough evaluation. This comprehensive handbook presents the latest methods for recognizing these more complex operations and offerrs alternative mixing designs for critical applications. The core mixing design topics discussed are: <ul><li>Homogeneous blending in tanks and in-line mixers</li> <li>Dispersion of gases in liquids with subsequent mass transfer</li> <li>Suspension and distribution of solids in liquids</li> <li>Liquid-liquid dispersions</li><li>Heat transfer</li> <li>Reactions, both homogeneous and heterogeneous</li></ul> Along with focusing on industrial design and the operation of mixing equipment, the Handbook of Industrial Mixing contains summaries of the foundations on which these applications are based. In order to accomplish this, most chapters are written by both an industrialist and an academic. Intended for the practicing engineer who needs to both identify and solve mixing problems, this book also provides concise discussions on theoretical background and uses many illustrative examples when covering applications, and it includes a CD-ROM that contains over fifty video clips and animations of mixing processes. These clips are accompanied by explanatory text.
