Process Modelling and Simulation in Chemical, Biochemical and Environmental Engineering

This book explores effective modelling and simulation approaches for solving equations. It provides a clear explanation of how to simplify complex processes at various levels with the help of a 'model sketch'. The second edition covers modelling of multi-stage processes and multi-stage, multi-phase systems with thermodynamic processes, including reactive distillation. Additionally, process intensification is introduced with modelling of electrochemical processes. A chapter on batch processes in filtration, adsorption, drying, distillation and batch reactors is included, backed by case studies. - Presents a systematic approach of model development in view of the simulation need - Discusses modelling techniques to model hydrodynamics, mass and heat transfer, and reactors for single- as well as multi-stage/multi-phase systems - Explores diffusion based on Stefan-Maxwell theory, including principal component analysis - Reviews dynamics models covering process dynamics - Includes enhanced case studies to illustrate simulations, including ANN This book is aimed at senior undergraduate and graduate students in chemical, biochemical and environmental engineering.

Ashok Kumar Verma retired as Professor in the Department of Chemical Engineering and Technology at Indian Institute of Technology (Banaras Hindu University) Varanasi. He holds a B.Sc. degree from Allahabad University, a B.E. degree in Chemical Engineering from University of Roorkee (now Indian Institute of Technology, Roorkee), an M.E degree in chemical engineering from Indian Institute of Sciences, Bangalore and a Ph.D. in Technology from Indian Institute of Technology, Kanpur. Ashok Kumar Verma joined the institute in 1984. He conducted post-doctoral research at Department of Chemical Engineering, University of Illinois, Chicago. His research experience includes modelling of liquid fluidized bed and heat transfer in slurry bubble columns. He has taught courses in modelling and simulation, process engineering, computer aided design, artificial intelligence in chemical engineering, transfer processes, and process control. His current activities include development of virtual lab, based on real time simulation, for chemical engineering courses. Ashok Kumar Verma has authored or coauthored about ten research papers appearing in a range of chemical engineering journals. He also authored or co-authored numerous papers in national and international proceedings and book titled 'Process design for Chemical and Environmental Engineering'. He has made presentations at several conferences and seminars and presented invited lectures at several workshops organised at other universities institutions and industries. Ashok Kumar Verma and his family reside in Varanasi, India.
