Energy efficient technologies and contribution of industries

The revolution in the field of science led to proliferation of Industries and these industries play a key role in the economic development of the society but the impact on the environment is a devastating one. Release of toxic gases into the atmosphere, soil degradation, and water pollution created global warming and unpredictable climatic changes. The energy, in the form of raw materials, power and other utilities, are consumed without taking into consideration of their importance and in this scenario, conservation of energy becomes significant to protect the environment. To achieve this, industries should adopt the energy efficient technologies to reduce the specific energy consumption and also to act as environment friendly. Such energy efficient technologies [1] have been adopted in a fertilizer industry at Chennai that have a remarkable impact on the protection of environment and lowest energy level among the naphtha based fertilizer industries in India. This study focuses on the various technologies adopted by this industry to reduce energy levels and protection of the environment. CO2 absorption system: Carbon-di-oxide emission to atmosphere is avoided, saving the environment. Hydraulic turbine resulted in energy savings of 0.071Gcal/MT of ammonia. Low temperature super methanation catalyst resulted in energy savings of 0.047Gcal/MT of ammonia. Total heat recovery system in Urea process resulted in the reduction of energy level to 7.9Gcal/MT from 9.9Gcal/MT. York Compressor reduces the ammonia emission to atmosphere. Vaporized naphtha burners for firing system resulted in the energy savings of 2–2.5Gcal/MT of Ammonia and saving the environment. Process air compressor resulting in energy savings of 0.02Gcal/MT of ammonia
