Industrial energy conservation contributes to solution of the global issues such as energy security and possible future exhaustion of oil. Industrial energy efficiency is a key ingredient in any national energy efficiency programme. Energy is one of the most important building block in human development, and, as such, acts as a key factor in determining the economic development of all countries. There is, therefore, an urgent need to conserve energy and reduce energy requirements by demand-side management and by adopting more efficient technologies in all sectors. In fact, energy is one of the pillars that support the entire superstructure of the modern civilization. This two-volume set summarizes various aspects of industrial energy consumption and conservation and is divided in two volumes. It discusses: energy efficiency technologies related to boiler, steam distribution and waste heat recovery, energy conservation in chemical process and allied industries, petroleum refineries and petrochemicals, plastic and rubber, tannery, textile, electrical, mechanical, cement, ceramic and glass, metallurgical and mining industries. A unique feature of the book is the chapter on nanotechnology in energy conservation.
