Industrial Utility Efficiency
When the design capabilities of an installed compressed air system didn’t align with real-world production needs at its ore processing mill in northern Michigan, Eagle Mine decided to move beyond theoretical compressed air concepts and deal in reality. After thorough analyses of its compressed air challenges and implementing a variety of solutions, the team at the mill bolstered the operation’s ability to efficiently mill approximately 2,200 metric tons of ore per day.
Sitting on his desk the day Brian began his new job as Plant Engineer for Carbo Ceramics’ McIntyre, GA facility was a proposal to purchase a new 150 HP air compressor as a backup machine. The facility already had six of these machines and, yes, all six ran almost continuously.
A compressed air system assessment saved this building materials manufacturer over \$518,000 per year in energy costs, with a simple ROI of 11 months.
Compressed Air Best Practices® Magazine spoke with Mr. Ed McGovern (VP Sales & Business Development) of PIAB North America.
This facility processes bulk food ingredients into finished packaged food products. The factory belongs to a division of a large corporation and was spending \$732,342 annually on energy to operate their compressed air system. This system assessment detailed twelve (12) project areas where yearly energy savings totaling \$214,907 could be found with a minimal investment of \$68,350. Due to space constraints, this article will detail only the higher impact project areas. The over-all strategy for improving this air system centers on improving specific power performance of the #3 centrifugal air compressor and reducing over-all demand with compressed air savings projects.
