Comprehensive guide to the design, installation, selection, and maintenance of agitators in the biofuels and renewable chemicals industries
Agitator Design Technology for Biofuels and Renewable Chemicals is a single-source reference on all the major issues related to agitator design for biofuel, written with the intention of saving the reader time by avoiding the need to consult multiple references or sift through many pages of text to find what is needed for agitator design in specific industries. The work presents a brief introduction of basic principles and relevant theory, then goes on to cover the real-world applications of these principles, including economic evaluations of alternatives as well as supplier evaluation principles.
To aid in quick and seamless reader comprehension, each chapter has the symbols used in that chapter listed and defined at the end. Overall, the work is written more as a how-to book than an academic treatise. The highly qualified author has included plenty of brevity throughout the pages with the hopes that readers go through the entire book as a single unit, rather than just skimming an occasional page or chapter as is common with other resources in similar fields.
Sample topics covered in the work include: - Avoiding common problems, such as using impeller diameters and speeds that would not result in even minimal solids suspension or liquid motion - Choosing the right impellers for the job, understanding how power draw and pumping are calculated, and becoming familiar with biofuel/biomass agitator sizing guidelines - The principles and limitations of scale-up and the most common non-Newtonian rheology applicable to biofuel applications - Designing lab tests and scale-up cellulosic hydrolysis agitation, plus the uses and limitations of Computational Fluid Dynamics (CFD)
As an easy-to-read and completely comprehensive resource to the subject, Agitator Design Technology for Biofuels and Renewable Chemicals is immensely valuable for professionals tasked with selecting agitation equipment or troubleshooting existing equipment, as well as those involved in planning activities and allocating resources related to project management.
