The branch of engineering which deals with producing, using, designing, transforming and transporting energy and materials is known as chemical engineering. It utilizes principles of chemistry, physics, biology, economics and mathematics. Some of the key concepts within this field are process design and analysis, transport phenomena, and plant design and construction. Process design deals with defining the type and size of equipment, and the materials of construction. Plant design and construction involves creating plans, specifying and providing economic analyses for plant modifications, pilot plants and new plants. Chemical engineering is primarily applied in the transformation of raw materials into usable products. This book covers in detail some existent theories and innovative concepts revolving around chemical engineering. It presents this complex subject in the most comprehensible and easy to understand language. Those in search of information to further their knowledge will be greatly assisted by this book.
