Energy Newsbriefs Blog

This current awareness service is prepared by the WSU Energy Program Library with funding from the U.S. Department of Energy State Energy Program. This information is provided for energy professionals and interested members of the public to highlight recent energy-related news, articles, and reports that discuss energy efficiency, energy conservation, and renewable sources of energy in engineering and policy circles.

Evaluating Air Compressor Cooling Systems

Compressed Air Best Practices, Aug. 2014, by Nitin G. Shanbhag.

"As the population continues to grow in the United States, industrial water use will need to continue to fall to help offset the increases in public-supply water use. Water-cooled compressed air systems provide an opportunity for sustainability managers to reduce associated cooling water consumption and costs. If switching to air-cooled air compressors is not possible, understanding the costs and the alternative types of liquid cooling systems is important."

Compressed Air System Simulation Software

"Over the years and many compressed air audits later, one thing has become clear: continuous monitoring is a key factor for efficient compressed air systems. Similarly, the only constant in a compressed air system is change. When new air applications are added, a line is down, air leaks grow or if maintenance is done to repair leaks in the system, the whole system is affected and responds accordingly. Due to the nature of compressed air systems, improvements may be quickly lost shortly after implementation and go unnoticed. System monitoring allows operators and facilities maintenance to see real time effects of changes to the system and respond with appropriate adjustments when necessary."

ASME EA-4-2010 - Energy Assessment for Compressed Air Systems. What’s it all about?

"The ASME EA-4 standard takes the same system approach that is taught in the Compressed Air Challenge® Fundamentals and Advanced Compressed Air System Management courses and provides a prescriptive but scalable process that can be tailored to each facility. Along with system definition, it sets requirements for organizing and conducting the assessment, analyzing the data, and reporting and documenting of the findings."

Energy-Efficient Compressed Air Piping Systems

Compressed Air Best Practices, May 2014, by Paul Johnson.

"A properly designed and maintained compressed air system that is energy efficient could save the user thousands of dollars each year. It will also minimize the risk of lost production by increasing the reliability of supply and improve the strength and safety aspect of operating a pressurized system. Every dollar saved on energy goes straight to the bottom line and is a very effective way to increase profits."

Four Action Items Save Money and Energy at a Refinery

Compressed Air Best Practices, May 2014, by Hank Van Ormer.

"This case study shows just how a large facility, which grows over time, is the right situation for a compressed air system assessment. Most optimization opportunities are present and the potential for quick wins and very attractive project ROI’s is very high. Piping systems, upgrading air compressors and air dryers, leak surveys, end uses, are all areas which were improved in the compressed air system at this refinery."

With Minimized Compressed Air Usage, AODDPs Provide an Energy-Efficient Solution

Pumps & Systems, May 2014, by Paul McGarry.

"A redesigned air-operated double diaphragm pump (AODDP) allows end users to reduce their energy costs."

Compressed Air System Design Recommendations for Food Processors

Compressed Air Best Practices, Mar. 2014, by Roderick Smith.
http://www.airbestpractices.com/industries/food/compressed-air-system-design-recommendations-food-processors

"The codes and recommendations put forth by the BCAS/BRC and by the VDMA provide the compressed air user and specifier in the food industry with some VOLUNTARY guidelines to consider when designing a compressed air system. The key word here is “voluntary”. These recommendations do not recommend the involvement of any inspectors or the creation of new regulations. The compressed air industry has simply shared very solid, unbiased, and practical recommendations to the food industries in their respective countries."
