Understanding Batch Chemical Processes

Thokozani Majozi is a full professor in the School of Chemical and Metallurgical Engineering at Wits University where he also holds the NRF/DST Chair in Sustainable Process Engineering. 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. Esmael Seid obtained his B.Sc. in Chemical Engineering from Bhair Dar University, Ethiopia. He then worked in process industry for three years after his B.Sc. before joining University of Pretoria, South Africa, in 2009, where he obtained his MScEng and PhD degrees in Chemical Engineering. Dr Seid has several publications in international refereed journals on design, synthesis, scheduling, and resource conservation, with particular emphasis on water and energy for multipurpose batch plants. He is currently a visiting

"Without a doubt, I would recommend this useful book to students and professionals alike who are interested in analysis, synthesis and design of batch processes because of the well-organized chapters, clear explanations, and industry-based case studies."— Hongguang Dong, Dalian University of Technology, China"This is a much needed and timely contribution that covers the fundamentals and applications of batch process modeling and design. The authors are very well recognized for excellent contributions in related areas. The book is ideal for educational purposes and for researchers and process engineers interested in the important field of batch processes."— Mahmoud El-Halwagi, Texas A&M University, USA"The book provides detailed discussion on mathematical modelling approaches for analyzing, synthesizing and design of batch processes. Heat and water integration of batch processes have been well presented in the book."— Denny K. S. Ng, University of Nottingham, Malaysia"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 presented in the material are important in this process as they are giving information about the flexibility of the mathematical formulation and guide the readers through the obtained results and potential alternatives."— Hella Tokos, Ynsect, Évry, Essonne, France"This book fills a major gap and provides a detailed and expansive resource for comprehensively modelling, integration and optimization of batch processes. Examples and case studies are well integrated into the book and support the methods outlined. The focus on water optimization and multi-purpose batch plants is a welcome addition. The clear presentation of state-of-the-art models and methods will make this book an indispensable resource for both the researcher and the practicing engineer."— Martin Atkins, University of Waikato, Hamilton, New Zealand"This book can be a good guideline for practicing engineers as well as graduate students interested in process systems engineering."— Santanu Bandyopadhyay, Indian Institute of Technology Bombay, India"This book presents a comprehensive and authoritative introduction of batch chemical process in scheduling, heat integration and water optimization. Emphasis is given to complex issues such as scheduling and optimization of energy and water use in multipurpose batch plants. Methods to reduce binary variables and computational time are presented in detail. In addition to covering the fundamentals of batch chemical process, the book also includes numerous case studies to illustrate the application and effectiveness of the proposed method. The book is a must read for process engineers, senior-level undergraduate students and first-year graduate students, and researchers in the area of process systems engineering."— Du Jian, Dalian University of Technology, China
