This book is written as a guide to industrial professionals, young engineers, entrepreneurs, and industrialists, and other stakeholders who need a huge energy in process industries in different forms through industrial/process equipment for several human needs. But the performance and efficiency of the equipment are not really taken care of during the operations and processes, which may be due to the dearth of proper knowledge or ignorance. Because of that, a large quantity of energy remains unutilized or wastage causing excess energy costs and subsequently generation of a huge quantity of carbon footprint indirectly which could be saved by proper performance and efficient management, and hence our Nature earth could be sustainable. In this book, the authors highlighted the performance and loss of efficiency of such industrial equipment during running. This attempt has been made to disseminate their sound, in-depth knowledge, and long experience achieved from several industries while working in different fields. The book explains the actual energy needed for performance, the reason for energy loss, and the scope of energy savings which can be possible by proper energy management. This book will also be apprehensible for all students of diploma, undergraduate & post graduate in the stream of electrical, mechanical, chemical, power, and all other engineering courses as a textbook as well as a reference book.
