Compressed Air Challenge: Maintaining Peak Compressed Air Efficiency

Maintenance Technology, Sept. 2014, by Ron Marshall.
http://www.maintenancetechnology.com/2014/09/compressed-air-challenge-maintaining-peak-compressed-air-efficiency/

"A well-maintained [compressed air] system will provide an uninterrupted supply of cool, clean and dry compressed air at a stable and appropriate pressure in the most efficient manner possible. Poorly maintained systems have frequent system shutdowns, heat or moisture problems, exhibit system pressures that fluctuate wildly at levels that are too high to produce efficiently, and typically waste air due to leakage.  ...here are several key maintenance-related points to consider for trouble-free compressed air system operation."

Energy Efficiency Advocates Optimistic About PACE Program [Texas]

The Texas Tribune, Oct. 7, 2014, by Jim Malewitz.
http://www.texastribune.org/2014/10/07/pace-loan-program-energy-efficiency-gains-momentum/

"PACE [Property Assessed Clean Energy] allows commercial and industrial property owners to use a property tax lien to finance energy efficiency upgrades like solar panels and water recycling systems. PACE programs bill an owner through the lien and forward payments to a private lender. Under a smooth-running program, property owners pay less than what they save on their energy bills. If a property is sold, the new owner inherits the debt — a rule meant to further reduce the risks of investment."

Evaluating Farm Slurry Extends Life & Performance [Pumps]

Pumps & Systems, Sept. 2014, by Paul Davies.
http://www.pump-zone.com/pumps/september-2014-evaluating-farm-slurry-extends-life-performance-0

"Pump manufacturers know that the engineering phrase “fit and forget” never holds true for rotating equipment. For all its reliability and longevity, a slurry pump that has been operating in a pit for several years will eventually fail. Several pumps can handle farming applications at a tenth of the initial cost for an application-specific slurry pump. However, replacing a cheaper, less effective pump every six months becomes a tiresome—and expensive—hassle for many farmers. This article features several examples of how selecting the right pump ensured worry-free operation in harsh pit service."

Energy Department Recognizes 11 Manufacturers for Energy Efficiency Achievements

Pre-Screening Unlocks Savings Potential in Large Pump Systems

Pumps & Systems, Sep. 2014, by Ray Hardee.
http://www.pump-zone.com/pumps/september-2014-pre-screening-unlocks-savings-potential-large-pump-systems

"When facilities—whether paper mills, refineries, or chemical or waste treatment plants—decide to implement pump system improvements, the first question is always the same: Where to begin? This month’s column looks at the pre-screening process, when plant management teams decide which system to tackle first. The pre-screening process quickly identifies which pump system has a high probability of improving plant operations, reducing total cost and increasing system uptime."

A 2014 ASHRAE Technology Award Case Study: 1st Place, Industrial Facilities or Processing Existing.

"The Fromagerie des Basques family cheese factory in Trois Pistoles, Quebec, Canada, transforms about 800,000 gallons (3 million L) of milk into cheese each year.... In 2011, a project was developed that included building a mechanical room, constructing a treatment plant to turn whey and white water into biogas to produce heat for cheese production, and modifying the high-temperature, short-time pasteurizer to use rejected heat to preheat milk. The projects reduced the amount of heating oil used by 64%, even with the addition of several buildings increasing the total square footage by 8,100 ft2 (753 m2)."  

The Fine Art of Making Energy Visible

Business Energy, Jul/Aug 2014, by Mark Scott Lavin.

/Energy_Visible_26497.aspx


"One of the boldest experiments in energy efficiency collaboration in the US is now well underway in Vermont, where cold winters and other factors drive some of the highest energy costs in the country. It’s spearheaded by a new kind of utility known as Efficiency Vermont and run by the non-profit Vermont Energy Investment Corporation (VEIC). This new utility is the first of its kind, though similar initiatives have emerged in Oregon, Washington DC, and the Ohio region. Efficiency Vermont provides electricity to stakeholders, not by building power plants, but by helping existing consumers use less energy and use it wisely."

Customized Pumping System Brings New Efficiencies to Mineral Processing

Maintenance Technology, Aug. 2014, by Grundfos Engineered Systems (GES) team.
http://www.maintenancetechnology.com/2014/08/customized-pumping-system-brings-new-efficiencies-mineral-processing/

"Energy-efficient pumps, intelligent pump-control logic and variable-frequency drives help the company process more minerals and cut energy use."

Evaluating Air Compressor Cooling Systems

Compressed Air Best Practices, Aug. 2014, by Nitin G. Shanbhag.
http://www.airbestpractices.com/sustainability-projects/cooling-systems/evaluating-air-compressor-cooling-systems

"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."
