Process Design for Chemical and Environmental Engineering

This book discusses the design methodology for chemical process equipment carrying out heat and mass transfer operations and various types of reactors. Process design is an important step before achieving a mechanical design of chemical process equipment. It requires comprehensive knowledge of thermodynamics, fluid flow, heat, and mass transfer operations, and chemical reaction engineering, which is covered by the various chapters in this book. It covers process design of (1) heat exchangers, condensers, and reboilers; (2) packed and stage columns for distillation and gas absorption in chapter; (3) liquid–liquid extractor and solid–liquid leaching systems; (4) cooling towers; and (5) four different types of catalytic reactors, packed bed, fluidized bed, slurry bubble column, and mechanically agitated slurry reactor.

The book emphasizes using correlations and equations in place of design data available in graphical or tabular forms to make it suitable for solving problems using spreadsheets and other software. It includes new correlations if not available in the literature and references to data available on web resources. The book covers all major topics for the course Chemical Process Engineering for undergraduate students and is also helpful in carrying out process design calculations for undergraduate design projects.

Ashok Kumar Verma retired in 2019 as a professor in the Department of Chemical Engineering and Technology at the Indian Institute of Technology (Banaras Hindu University) Varanasi. He held the post of Head of the Department and Chairman of the Design and Innovation Hub at IIT (BHU).

He holds a B.Sc. degree from Allahabad University, a B.E. degree in chemical engineering from the University of Roorkee (now Indian Institute of Technology, Roorkee), a M.E. degree in chemical engineering from the Indian Institute of Sciences, Bangalore, and a Ph.D. in chemical engineering from the Indian Institute of Technology, Kanpur. He carried out postdoctoral research at the Department of Chemical Engineering, University of Illinois, Chicago. His research experience includes modeling liquid fluidized beds and heat transfer in slurry bubble columns. He has taught courses in process design, process engineering, mass and heat transfer, and a number of other core and elective courses. His research areas include heat and mass transfer in bubble columns, fluidized beds, and development of acoustic and image processing techniques for the measurement of bubble properties in bubble columns.
