Designed as a textbook for the undergraduate students of chemical engineering and related disciplines such as biotechnology, polymer technology, petrochemical engineering, electrochemical engineering, environmental engineering and safety engineering, the chief objective of the book is to prepare students to make analysis of chemical processes through calculations and to develop systematic problem-solving skills in them. The text presents the fundamentals of chemical engineering operations and processes in a simple style that helps the students to gain a thorough understanding of chemical process calculations. The book deals with the principles of stoichiometry to formulate and solve material and energy balance problems in processes with and without chemical reactions. With the help of examples, the book explains the construction and use of reference-substance plots, equilibrium diagrams, psychrometric charts, steam tables and enthalpy composition diagrams. It also elaborates on thermophysics and thermochemistry to acquaint the students with the thermodynamic principles of energy balance calculations. The book is supplemented with Solutions Manual for instructors containing detailed solutions of all chapter-end unsolved problems.NEW TO THE SECOND EDITION • Incorporates a new chapter on Bypass, Recycle and Purge Operations • Comprises updations in some sections and presents new sections on Future Avenues and Opportunities in Chemical Engineering, Processes in Biological and Energy Systems • Contains several new worked-out examples in the chapter on Material Balance with Chemical Reaction • Includes GATE questions with answers up to the year 2016 in Objective-type questions KEY FEATURES • SI units are used throughout the book. • All basic chemical engineering operations and processes are introduced, and different types of problems are illustrated with worked-out examples. • Stoichiometric principles are extended to solve problems related to bioprocessing, environmental engineering, etc. • Exercise problems (more than 810) are organised according to the difficulty level and all are provided with answers.

All engineering disciplines have been developed from the basic sciences. Science gives us the information on the reasoning behind new product development, whereas engineering is the application of science to manufacture the product at the commercial level. Biological processes involve various biomolecules, which come from living sources. It is now possible to manipulate DNA to get the desired changes in biochemical processes. This book provides students the knowledge that will enable them to contribute in various professional fields, including bioprocess development, modeling and simulation, and environmental engineering. It includes the analysis of different upstream and downstream processes. The chapters are organized in broad engineering subdisciplines, such as mass and energy balances, reaction theory using both chemical and enzymatic reactions, microbial cell growth kinetics, transport phenomena, different control systems used in the fermentation industry, and case studies of some industrial fermentation processes. Each chapter begins with a fundamental explanation for general readers and ends with in-depth scientific details suitable for expert readers. The book also includes the solutions to about 100 problems.
