Assessment of energy-saving opportunities of cement industry in Iran

Abstract:- Growing concerns arise about energy consumption and its adverse environmental impact in recent years in Iran in which cause manufactures to establish energy management groups. Cement production has been one of the most energy intensive industries in the world. Focusing on energy consumption reduction efforts through process improvement, production management and introducing new technologies can achieve significant results. This study, based on conducting on-site energy audits of over 30 cement firms in Iran during 2004–2005, discovered the following energy-saving potentials: electricity savings of 223.5*106 KWh equivalent to 11.3M$, fuel oil savings of 168*106 Lit equivalent to 39.4M $ in FOB prices. The present paper will study the energy consumption in cement industry in Iran through real auditing and identify technological opportunities in order to decrease energy consumption of the relevant factories, increase the productivity, and improve the production process. Relevant standards planned by government that can provide significant potentials, are discussed too. Key-words:- cement industry, energy auditing, energy conservation, heat recover
