Meat Processing Plant Drops Compressed Air Costs 60%

Compressed Air Best Practices, Jan/Feb 2016, by Ron Marshall.

"One of the statements made in the Compressed Air Challenge’s Fundamentals of Compressed Air Systems seminar is that improvements can always be made to every compressed air system, including new ones. The statement definitely applies to a Canadian pork processing facility built a few years ago. This article is based on a compressed air audit performed two years into the life of a brand new plant. The audit found numerous problems and made recommendations that helped reduce plant compressed air operating costs by 60 percent."

Hydraulic Institute Supports the Pump Industry as the DOE Issues Final Rules on Test Procedures and Energy Conservation Standards For Commercial And Industrial Pumps

Water Online, Jan.. 6, 2016.

"The Hydraulic Institute, North America’s largest pump trade association, announces the release of two final rules (1) The Energy Conservation Standard and (2) The Test Procedure for Commercial and Industrial Pumps by the United States Department of Energy (DOE). The rulings are now available through the HI website. The compliance date for the Energy Conservation Standard will be 2020 and DOE estimates it will save 0.29 quadrillion BTUs (2020 – 2050)."

A Systems Approach Helps Rockline Industries Retrofit a Compressed Air System

Compressed Air Best Practices, Jan/Feb 2016, by Andrew Chase Harding and Darin Nutter.

"Rockline Industries is one of the largest global producers of consumer products, specializing in wet wipes and coffee filters. The company contacted the Arkansas Industrial Energy Clearinghouse after identifying that the compressed air system in their Springdale, Arkansas facility was a potential source of significant savings. Experts from the Clearinghouse then began working with Rockline Industries, representatives of the electric utility, and a local compressed air vendor to perform a complete evaluation of the system."

Choosing the Proper VFD can Limit Harmonics

Pumps & Systems, Dec. 2015, by Jeffery Lovelace.

"Facilities predominantly using these drives may face concern from power utility companies. Variable frequency drives (VFDs) have vastly evolved during the last 25 years.

Pumps: State of Global Efficiency Standards (Part 2 of 2)

Pumps & Systems, Dec. 2015, by Lev Nelik.

"Part 1 of this series discussed the lack of a formal, comprehensive global standard on pump efficiency and the importance of understanding the difference between actual field efficiencies of installed pumps and the initial original equipment manufacturer (OEM) efficiencies. As noted in part 1, studies show that the efficiencies of installed pumps are commonly reduced by 10, 20 and often close to 50 percent below the OEM-quoted (rated point). Several factors can contribute to this trend...."

8 Reasons Pumps Operate Off Their Curves

Flow Control, Oct. 30, 2015, by Randy Riddell.

"The plant is having process issues, and the culprit appears to be a process centrifugal pump. The area production manager has asked you to check the pump to see if it is operating on its curve. “Pump won’t pump, make pump pump,” he says. Sounds like a reasonable request. However, other questions need to be answered, such as: Where is the pump running on its curve? If it is not running on its curve, why?"

Calibrate Faster, Smarter & More Accurately [Pump Systems]

Pumps & Systems, Oct. 2015, by Jim Shields.

"As the price of raw materials fluctuates, industries must minimize costs and maximize profit margins. One way to control costs is to become leaner and more efficient. Every time companies remove waste in their processes, they save money. That includes maintenance and efficiency of pumps that move materials through a facility."

Aluminum Plant Meters Compressed Air Flow to Solve Capacity Issues

Compressed Air Best Practices, Oct. 2015, by Jack Sine.

"A major Midwestern aluminum plant was experiencing dwindling compressed air capacity, primarily due to air leaks. If those capacity issues went unresolved, the facility would have needed rental compressors to keep up with demand. Instead, they turned to flow metering to identify and fix the leaks. In this article, they share their solutions with others who may be having similar difficulties."

What Boiler MACT Means to an Energy Engineer

Hudson Technologies, Oct. 15, 2015.

"Boiler MACT [Maximum Achievable Control Technology] is one of the first federal environmental regulations that have specifically called for conducting an energy assessment as a compliance activity. Energy assessments are nothing new; but how does integrating them into an environmental compliance activity impact the assessment process? As energy engineers, what can we learn from this new frontier?"

Steel Mill Energy Audits Include Air Compressor Performance Testing

Compressed Air Best Practices, Oct. 2015, by Eric Lee.

"EnSave, an energy auditing company based in Richmond, Vermont, recently performed compressed air audits at two facilities of a leading U.S. steel manufacturer. Both plants are mills that melt, cast, and roll steel to produce a variety of products, including: rebar, merchant bar, steel flats, rounds, fence posts, channel bar, steel channels, steel angles, structural angles and structural channels."
