Compressed Air Best Practices - March 2009 - (Page 22) ® | 03/09 Focu Industry ENERGY MANAGEMENT ocus ndust stry NE ANAGEMENT | ASSESSMENT IMPROVES ELECTROPLATER PRODUCTION AND SAVES ENERGY The Project The primary demand for compressed air in the plant was from a series of compressed air-driven nozzles that atomized water to rinse away chemicals used during the plating process. Working with a nozzle manufacturer, Scales designed a process change that enabled the strip washing nozzles to use water alone instead of in conjunction with compressed air. Eliminating the air-driven strip washing sharply reduced the plant’s compressed air requirements. The assessment also found that a filter press was being fed an unneeded, constant supply of compressed air. Scales’ engineers worked with the plant employees to install high-pressure, off-line air storage supplied by a 5-hp reciprocating compressor to accommodate the high-volume, intermittent demand of the filter press. This further reduced the load on the main compressor. Finally, a leak detection and repair campaign led to additional compressed air energy savings. The combination of all these measures reduced the plant’s air demand to where it could be met with a smaller compressor. The plant was able to replace their 300-hp compressor with a 75-hp variable displacement compressor and a new, energy-efficient dryer. Project p Replaced 300-hp centrifugal unit with 75-hp rotary screw compressor Added 5-hp reciprocating compressor package with compressed air storage Added 75-hp compressor for back-up Converted compressed air-driven strip washing nozzles to water-driven nozzles Identified and repaired leaks Costs after utility rebate: $72,500 p p p p p Benefits p p p p Annual energy savings of $153,000 and 1,631,000 kWh Production benefits of $50,000 annually Other annual savings of $49,000 Simple payback of less than 4 months 22 www.airbestpractices.com http://www.airbestpractices.com
