Although batch processing has existed for a long time, designing these processes and unit operations has been considered an onerous task that required computational efforts. Design of these processes is made more complex because of the time dependent nature of the process and the allowable flexibility. More often than not, every unit encounters optimal control problems. Therefore, traditional design books have not covered batch processing in detail. Filling this void, Batch Processing: Modeling and Design describes various unit operations in batch and bio-processing as well as design methods for these units.
Topics include:
- Batch distillation operating modes and configurations
- Batch absorption operations based on the solubility difference
- Batch adsorption based on differential affinity of various soluble molecules to solid absorbents
- Batch chromatography for measuring a wide variety of thermodynamic, kinetic, and physico-chemical properties
- Batch crystallization where a phase is used to find the supersaturation at which point material crystallizes
- Batch drying that stresses the phase diagram of water to describe this operation
- Batch filtration using a porous medium or screen to separate solids from liquids
- Batch centrifugation where centrifugal force is used for separation
Batch processes are widely used in pharmaceutical, food, and specialty chemicals where high value, low volume products are manufactured. Recent developments in bio-based manufacturing also favor batch processes because feed variations can be easily handled in batch processes. Further, the emerging area of nanomaterials manufacturing currently uses batch processes as they are low volume, high energy intensive processes. With examples, case studies, and more than 100 homework problems, this book describes the unit operations in batch and bioprocessing and gives students a thorough grounding in the numerical methods necessary to solve these design problems.

"…is very timely as there are only very few texts dealing with the subject in a unified manner. The book provides a good overview of batch reaction and separation processes. In particular there is a comprehensive treatment of batch separation processes that extents over nine chapters."
––Dominique Bonvin, École polytechnique fédérale de Lausanne, Switzerland"The selection of topics is quite comprehensive… a comprehensive coverage of batch processing. A book dedicated to this topic could become a 'standard text'."
––Richard Turton, West Virginia University, Morgantown"My impression is that many students and practitioners will find this book to be very helpful – especially those that have little experience in modeling and optimizing batch processes. To these people, the coverage in specific separation areas is likely to be attractive – depending on its comprehensiveness."
