Harnessing the Potential of Energy Storage

Power Engineering, May 2017, by Richard McMahon and Lola Infante.
http://www.power-eng.com/articles/print/volume-121/issue-5/features/harnessing-the-potential-of-energy-storage.html

"Energy storage has been called a "game changer," a "panacea," and a "disruptor." It has garnered widespread interest from electric companies, residential customers, businesses, manufacturers, regulators, and policymakers. Its potential for growth has been described as "astronomical" and "colossal," and its benefits sometimes touted as incalculable. Indeed, energy storage has the potential to be a true game changer."

All Eyes on Hydropower

Hydro Review, May 2017, by Michael Harris.

"With the legislative framework and public sentiment leaning heavily toward renewable generation around the world, hydropower continues to be a valuable commodity. Data pulled from a number of recent studies shows its growth and provides hints as to where it is going."

"From addressing temporary fixes of the past to preparing existing cooling for the future, take in these 16 tips for successful projects in high-pressure environments."

VSD Chillers Deliver Energy Savings Under Real World Operation

Chiller & Cooling Best Practices, May 2017, by Fred Berry.

"Manufacturers are under continual pressure to control costs without affecting operations or worker comfort and safety. Because energy ranks as one of the largest operating expenses, improving energy efficiency of mechanical cooling systems is one of the best ways to reduce operating costs. In a typical water-cooled chiller plant, the chiller itself accounts for most of the energy consumption. That’s why improving chiller efficiency is critical to controlling operating costs."

A Critical Role: Pumps and Valves are Key to System Efficiency

Water Efficiency, May 2017, by Carol Brzozowski.

"When it comes to moving water efficiently, pumps and valves play a critical role. Some efficiency concerns focus on the wastewater utility sector, where “the EPA state revolving funds are going to fixing failing existing sewers—not so much extending into new service areas as much as they have been, but now repairing the leaky infrastructure,” says George Vorsheim, director of marketing and communications for Environment One Corporation (E/One)."

Choosing a Pump for the Total System

Pumps & Systems, May 2017, by Ray Hardee.

"In this two-part series, we will look at a simple system consisting of a collection tank, a pump, distribution tank and the interconnecting piping as shown in Figure 1. This simple system is often used for distribution of water, bulk materials transfer, industrial waste collection and agricultural irrigation."

Vacuum System Fundamentals for “Compressed Air People”

Blower & Vacuum Best Practices, April 2017, by Tim Dugan.
http://www.blowervacuumbestpractices.com/technology/rough-vac/vacuum-system-fundamentals-compressed-air-people

"If you want to understand vacuum systems, you have to get out of the ruts, and slog through the mud and bounce over the rocks a bit.  If you’re a “compressed air person”, think outside the box for a few pages with me.  I am going to borrow some terms from the “pump people” to explain how vacuum systems are similar, yet different from compressed air systems. There are several ruts to get out of.  Remembering what changes and what doesn’t, what is controlled, and how to design systems for optimal energy consumption."

The Heart of Pneumatic Conveying Systems – Positive Displacement Blower Calculations

Blower & Vacuum Best Practices, April 2017, by Roger E. Blanton.
http://www.blowervacuumbestpractices.com/industries/conveying/heart-pneumatic-conveying-systems-%E2%80%93-positive-displacement-blower-calculations

"The heart of the pneumatic conveying system (air mover, solids feeder, pipeline, and separator) is the air mover. Correctly specifying the volumetric flow rate and pressure levels required to move the material will determine system reliability.  One must also look at pipe size, distance, and the weight of the material being moved. A company specializing in the design requirements of pneumatic conveying systems is best consulted for evaluating these requirements and specifying the required air or gas flow rate for the system."

OSHA Standard 29 CFR 1019.134 Grade D Compressed Breathing Air Requirements

Compressed Air Best Practices, May 2017, by Nancy Aulisa.
http://www.airbestpractices.com/standards/nfpa-99-medical-air/osha-standard-29-cfr-1019134-grade-d-compressed-breathing-air-requirem

"Compressed air, commonly called Industry’s fourth utility, is the most common utility used in a typical industrial facility. Compressed air is used in more than 70 percent of all manufacturing activities including supplying breathing air to personnel using supplied air respirators. Hazardous breathing conditions exist in many routine industrial operations, such as chemical manufacturing, hospitals, abrasive blasting, paint spraying, industrial cleaning, and arc welding. In these and other operations that introduce contaminants into the workplace, supplied-air respirators, air filtration systems and carbon monoxide monitors are frequently used for worker protection."

Making Sense of Compressed Air at a Huge Chemical Plant

Compressed Air Best Practices, May 2017, by Don van Ormer.
http://www.airbestpractices.com/industries/oil-gas/making-sense-compressed-air-huge-chemical-plant

"A chemical plant spends an estimated $587,000 annually on electrical energy to operate their compressed air system. In addition, the plant has an expenditure on rental air compressors of equal or greater size - but this will not be covered in this article. The plant was built in the 1940s and modernized in the 1970s. The plant generates its own power and serves many processes. The average cost per kWh is $0.0359."
