I dedicate this book to my late father‐in‐law, Richard Durchholz, for inspiring me as an engineer and a person; to Wayne Ramsey, for mentoring me and giving me the opportunity to design the largest fermenters built by Chemineer up to that point; to Ms. Jian Li, my colleague and friend, for helping me to succeed in managing the China office and understanding Chinese culture, and my wife, Kim Benz, for encouraging me and supporting me in the massive undertaking of writing this book.
Preface
This is a book about fluid agitation, as applied to gas–liquid systems such as fermenters or bioreactors (We will use those terms interchangeably in this text.). The specific focus is on mechanically agitated systems, consisting of a closed vessel with a rotating shaft and impellers, as this is the most common and versatile way to achieve process objectives in a gas–liquid system. Though airlift and bubble columns have also been used, they will not be discussed in any detail here, as that is not the focus of this book.
Many books have been written about fluid agitation. Many books have also been written about fermentation. Much, though not all, of the material in this book has been covered in such books. However, all such books cover much more than agitator design for bioreactors. For example, typical books on agitation cover topics such as solids suspension (almost never an issue in fermentation), highly viscous systems (>50 000 cP), specialized impellers such as helical ribbons, anchors, augers, and others that have no use in fermenters, mixing in high‐yield stress fluids such as paper stock, etc. Likewise, books on fermenter design usually cover some topics on agitator design but also cover feeding strategies, reaction kinetics, cell metabolism, sensitivity to concentration and temperature changes, product recovery, and a whole host of other topics. Little has been published in such books about how to acquire the proper pilot data for agitator design, or how to minimize energy consumption.
The main purpose of this book is to be a single‐source reference on all the major issues related to agitator design for bioreactors. It is intended to save the reader time by avoiding the need to consult multiple references or sift through many pages of text to find what is needed specifically for fermenter agitator design. This book will also cover important related topics such as heat transfer, power cost, basic agitator mechanical design, and vendor bid evaluation.
