Abstract
Energy audit is an inspection, survey and analysis of energy flows for energy conservation to reduce the amount of energy input into the system without negatively affecting the output. Energy audit is thus a reliable and systematic approach in the industrial sector. Indirectly energy conservation activity reduces greenhouse gas emissions. By considering these points resent work was carried out in production plant of Phosphate India Pvt. Ltd. Jamarkotda Road, Udaipur, Rajasthan (India) to evaluate energy consumption pattern and energy saving in plant. This study presents the electrical and thermal energy auditing in chemical industry. The study aimed to find energy saving opportunity in lighting system, induction motors, spin flash dryer, hot air generator and suggest possible application of renewable energy sources.
The individual energy consumption was evaluated by efficiency calculations of utilities according to BEE standards and simultaneously pointed out energy saving opportunities. The annual wastage of energy in plant through lighting system was found 528.24 kWh. Efficiency test of induction motors were showing low power factor. An efficiency of spin flash dryer (for drying chemicals) was 32.20 per cent. The hot air generator (HAG) efficiency calculations were performed by direct and indirect method, which was found 36.44 per cent and 40.27 per cent respectively. Suggested application of 2 kW SPV system which could save Rs 45900 annually with approximate payback period of 63 months compared to conventional electricity and gave suggestions for efficiency improvement in existing systems. Also suggested to make insulation to dryer and supply excess air to HAG which can save 0.6 and 5.4 kg/h of coal respectively.
