Poultry Plant Reduces Compressed Air Use by 44%

By Don van Ormer, Air Power USA

A major poultry processor and packager spends an estimated $96,374 annually on energy to operate the compressed air system at its plant located in a southern U.S. state.  The current average electric rate, at this plant, is 8 cents per kWh.

Compressed Air System Commissioning Part 1: Why do it?

By Tim Dugan, P.E. President, Compression Engineering Corporation

“Retro-Commissioning” (ReCX) of compressed air systems has become a trendy activity with many utility demand-side-management programs emerging in the last 5-10 years.  This is intended to be the process of “tuning up” a compressed air system, getting low cost savings from mostly adjustments and repairs.  The term was borrowed from the building/HVAC industry, where it means to get a system operating as it was originally “commissioned”.

Regenerative Desiccant Compressed Air Dryers

By Donald White, Chief Engineer, Aircel

Compressed air is dried to prevent condensation and corrosion which can disrupt manufacturing processes and contaminate products. Water is the primary promotor of chemical reactions and physical erosion in compressed air systems. A myriad of desiccant dryer designs have been devised to provide “commercially dry” air, air having a dew point of -40°F or less, to prevent corrosion. Desiccant dryers use solid adsorbents in granule form to reduce the moisture content of compressed air.

Centrifugal Air Compressor Basics Part II - Understanding the Basic Performance Curve

by Hank van Ormer, Contributing Editor

A centrifugal air compressor operates over a range of flows and discharge pressures. The operating performance curve is shaped by the selected individual internal components and affected by operating conditions such as inlet pressure, inlet temperature, and cooling water temperature. The process of dynamic compression, as applied in a centrifugal compressor operating stage, is velocity and kinetic energy converted to pressure and temperature as the flow is restricted.
