Experimental Investigation on Energy Efficiency of Electrical Utilities in Process Industries through Standard Energy Conservation Practices

In this research paper energy uses and energy conservation opportunities for process industry is presented. It has been found that process industries consume a substantial amount of energy. Excessive use of energy is usually associated with many process plants in India. The study is based on the realization that enormous potential exists for cost effective improvements in the existing energy using equipments. Through the method of energy audit power rating, operation time, power factor and other important details of all the machines/equipments were collected for the selected industry. The measured data was analysed to find energy conservation opportunity. Energy saving techniques like, energy efficient pumps, stopping of air leakages, air compressor efficiency improvement was considered for energy conservation. Energy saving details was calculated with cost benefit analysis. Energy conservation implementation program was carried out for Centrifugal pumping system, Air compressor system, as per the management consent and requirement in the the selected industry. It has resulted in total saving of 2,29,369 electric units (kWh/year) and annual energy saving of Rs. 13,43,670 with an investment of Rs 2,45,000.
