Chemical engineering is a branch of engineering that focuses on the production, use, design, transformation, and transportation of energy and materials. It integrates principles from chemistry, physics, biology, economics, and mathematics. Key concepts within this field include process design and analysis, transport phenomena, and plant design and construction. While process design involves determining the type, size, and materials of equipment, plant design and construction deals with the development of plans, specification of equipment, and economic analysis for plant modifications, pilot plants, and the construction of new facilities. Chemical engineering is primarily concerned with the conversion of raw materials into useful products. This book provides comprehensive insights into the field of chemical engineering. It elucidates the concepts and innovative models around prospective developments with respect to the field. In this book, constant effort has been made to make the understanding of the difficult concepts of the subject as easy and informative as possible, for the readers.
