Industrial Utility Efficiency    


For Imerys S.A. there’s little question about the importance of managing dust collection systems it uses to control and reduce harmful particulates in its worldwide minerals processing facilities. And now there’s zero doubt about the tremendous energy savings it stands to save by reducing the amount of compressed air needed for these same dust collectors.
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.
