Industrial Utility Efficiency

Leaks

Given that compressed air leak management programs are meant to save energy, reduce CO2 emissions, and generate ROI, DENSO’s Maryville, Tennessee, manufacturing facility can definitively say it has scored a trifecta when it comes to results – and reaped benefits beyond hard numbers alone.

Maintenance Saves Energy: Automatic Leak Detection on OEM Machines

Why So Many Air Leaks - Even Today?!

Energy conservation has been much talked about lately, in the media, the government, and at the water cooler. Lean manufacturing is also a popular topic these days, as are any ways to increase productivity, reduce costs, and increase profitability.

 

Advanced Air Leak Detection Services

“Instead of adding supply equipment, we fix air leaks and incorporate high-efficiency air nozzles, blower packages and point-of-use receivers.” These demand-side actions stabilize compressed air system pressure and this ultimately increases production output, reduces production down-time and spoilage costs, and decreases the power costs of the compressed air system.

Compressed Air Leak Measurement Leads to Savings

This Midwestern prepared food company now spends \$269,463 annually on energy to operate their compressed air system. This figure will increase as electric rates are raised from their current average of 6.2 cents per kWh. The set of projects recommended below will reduce these energy costs by \$112,902 or 41%. In addition, these projects will enhance productivity and quality and reduce equipment maintenance costs. Estimated costs for completing the projects total \$146,102, which represents a simple payback of 15.6 months.

Finding and Fixing Leaks

Understanding the supply side of the system is important, but more important is first looking at compressed air demand. One demand that is consistently in need of attention in industrial facilities is the air flow caused by leaks.

Ultrasound Leak Tests on Heat Exchangers

The secret to success is to understand the nature of what type of leak produces a detectible ultrasound and what does not, along with the techniques that can be used for effective leak identification.

Four Action Items Save Money and Energy at a Refinery

This refinery currently spends \$735,757 annually on the electricity required to operate the compressed air system at its plant. The group of projects recommended in the system assessment will reduce these energy costs by an estimated \$364,211 (49% of current use). Estimated costs for completing the recommended projects total \$435,800. This figure represents a simple payback period of 14.4 months. The firm also reduced compressed air demand by 732 scfm allowing them to save \$441,544 by down-sizing the back-up rental diesel air compressors.

Inappropriate-Use Assessment Saves 1,881 scfm

This factory currently spends \$735,757 annually on the electricity required to operate the compressed air system at its plant. The group of projects recommended in the system assessment will reduce these energy costs by an estimated \$364,211 (49% of current use). Estimated costs for completing the recommended projects total \$435,800. This figure represents a simple payback period of 14.4 months.

Compressed Air Leaks: Fact vs. Myth

Compressed air leaks - every system has them.  Is a leak identification and control program economically rewarding and/or necessary? Upper management sometimes doesn’t recognize the true cost of not repairing air leaks.  Knowing the high cost of compressed air, why wouldn’t every facility with a compressed air piping system implement a continuous leak identification and repair program?

Sustainability at RR Donnelley

Sustainability at RRD starts with a philosophy. It is then executed through a global policy and objectives. RRD’s philosophy does not see sustainability as making a choice between being cost-effective and improving environmental impacts. On the contrary, sustainability represents integrating these two factors. This philosophy guides our sustainability objectives and strategies.
