In the present scenario importance of an energy conservation increased day by day. There are various utilities in industries in practice like Chillers, Cooling Towers, Blowers, Fans, Motors, Furnaces, Pumps and Air Compressors in manufacturing industries plays vial role in energy consumption. Energy savings is possible increasing either the efficiency or replacement by efficient utility. It has been found that among all the utilities, Air Compressors are the least efficient utilities. It has been observed that compressed air system installed in early stage and due to ageing effect as well as lack of maintenance an efficiency of compressor is dropped down. In proposed work, Performance analysis of four air compressors has been carried out using “pump up test” (PUT) and losses by “leakage test” at different locations has been calculated large scale gear manufacturing industry. Considerable solution in terms of savings has been provided by providing priority base run of air compressors. Additional solution with variable frequency drive has also been also proposed. It has been proved that alternation of both mentioned test able to provide 5-15% additional amount of energy savings.

Once designed, mine compressed-air systems tend to operate at peak levels throughout the life of the mine, despite there being significant periods when this air quantity is not required. This is mainly due to lack of appropriate compressor controls. Consequently, such compressed-air systems are inefficient and wasteful. A compressed-air system at a South African gold mine was retrofitted with an automatic compressor control system featuring compressor cascading and pressure bandwidth control. The goal was to implement a simple demand-side management (DSM) strategy to afford meaningful electrical energy savings. The automatic control strategy realised a saving of 1.25 MW (on a baseline of 7.22 MW) during Eskom’s evening peak demand window. This represents a reduction of 17.3% in electrical power consumption during the evening peak period, and savings of nearly R2.9 million per year.

Potential Energy Saving

Energy efficiency subject has been gaining importance in maritime sector. The compressed air is a valuable energy source in operational manner, by the reason of intrinsic lack of efficiency in pressurization process. Operational pressure and leakage rate are the major variables which affect operational efficiency of the system. This study aims to reveal potential energy saving for the compressed air system. To this end, several pressure ranges, 29-30 bars to 14-18 bars, and different leakage rates 2.4% to 45% are evaluated. After the data was obtained from ships, thermodynamic calculations had been carried out. Optimization of pressure saves 47.3% in daily power requirement, 58,2% in compressed air unit cost, 18.4 and 57.4 tons of reduction in fuel consumption and CO2 emissions in a year respectively. High leakage rates can cause 2.7 times more power and fuel consumption. Finally, operating load, as an important indicator of compressor, makes imperfections identifiable.

Necessary Evil

It is widely accepted that industrial and commercial electricity users will continue to be increasingly challenged to reduce costs in order to be more competitive in their local, national and international market place. Today’s forward thinking and effective managers are viewing and managing the industrial compressed air system as an asset, not a necessary evil. Paper published with permission.
