Book Description

Batch chemical processes, so often employed in the pharmaceutical and agrochemical fields, differ significantly from standard continuous operations in the emphasis upon time as a critical factor in their synthesis and design.

With this inclusive guide to batch chemical processes, the author introduces the reader to key aspects in mathematical modeling of batch processes and presents techniques to overcome the computational complexity in order to yield models that are solvable in near real-time. This book demonstrates how batch processes can be analyzed, synthesized, and designed optimally using proven mathematical formulations. The text effectively demonstrates how water and energy aspects can be incorporated within the scheduling framework that seeks to capture the essence of time. It presents real-life case studies where mathematical modeling of batch plants has been successfully applied.

His main research interest is batch chemical process integration, where he has made significant scientific contributions that have earned him international recognition. Some of these contributions have been adopted by industry. Prior to joining Wits, he spent almost 10 years at the University of Pretoria, initially as an associate professor and later as a full professor of chemical engineering. He was also an associate professor in computer science at the University of Pannonia in Hungary from 2005 to 2009. Majozi completed his PhD in Process Integration at the University of Manchester Institute of Science and Technology in the United Kingdom. He is a member of Academy of Sciences of South Africa and a Fellow for the Academy of Engineering of SA. He has received numerous awards for his research including the Burianec Memorial Award (Italy), S2A3 British Association Medal (Silver) and the South African Institution of Chemical Engineers Bill Neal-May Gold Medal. He is also twice a recipient of the NSTF Award and twice the recipient of the NRF President’s Award. Majozi is author and co-author of more than 150 scientific publications, including 2 books in Batch Chemical Process Integration published by Springer and CRC Press in 2010 and 2015, respectively.

"The authors develop the key aspects of batch processes – modeling, scheduling, heat integration, and water optimization systematically. Each topic is covered in detail with excellent illustrations and case studies. This will provide a strong foundation to senior undergraduate and graduate students wishing to learn about batch systems."
— Rajagopalan Srinivasan, Indian Institute of Technology Gandhinagar, USA

"Taking in consideration that batch processes are often neglected in training of chemical engineers, especially from the perspective of process integration, this book is a valuable aid in knowledge transfer to the industry. The book is focused on mathematical methods giving an excellent review of their strengths and limitations with special attention on problem complexity which greatly contributes toward high computational cost, a major concern in industrial scale application. Detailed illustrative examples and industrial case studies presente
