| | OPTIMIZING PULP & PAPER MILL COMPRESSED AIR SYSTEMS |
 | | An investment-grade compressed air audit, analysis, design, and upgrade in an industrial facility requires a thorough understudying of original design basis, current problem definition, goal settings, load assessment, base case model development, and an ability to conduct unlimited "what if" analysis to determine the cost-effective efficiency improvement measures. |
 | | As usual, the compressed air utility was expanded on as-needed basis, but without optimizing electrical energy consumption of various compressor units that were partly loaded, under utilized and poorly designed as an integrated utility system. |
 | | The total design capacity of six compressors was 4,137 ACFM at 100 psig, the compressed air load was estimated to be 3,675 ACFM and the upgrade plan was based on the average compressed air use of 3,300 ACFM. |
