COMPRESSED AIR

Compressed air efficiency: beyond leak repair

"Are You Wasting Money Fixing Compressed Air Leaks" was written by Ron Marshall and Bill Scales for the Compressed Air Challenge, and appears in the September 2011 issue of Maintenance Technology. The article explains inaccuracies common to the calculation of savings from compressed air leak repairs, and suggests changes to compressor controls to maximize efficiency and reduce costs.

ENERGY MANAGEMENT

Cement plant energy savings

"Reduce Energy Consumption: Cement Production," written by Patrick Murray of Rockwell Automation and published in the September 2011 issue of Control Engineering, provides an overview of the steps necessary to reduce manufacturing plant energy consumption, using cement plants as a study subject. The basics of energy assessment, monitoring, load profile, power quality monitoring, and cost allocation are summarized, and a typical audit scope and timeline are presented.

Incorporating ISO 14001 into a sustainability management plan

A three-part series of articles from Sustainable Plant, "How Sustainability Dovetails with ISO 14001," outlines how manufacturing facilities can incorporate the international environmental management standard ISO 14001 into a comprehensive facility-wide sustainability management system. Part I, Energy and Waste, focuses on energy savings and solid waste recycling. Part II, Safety, covers plant safety management and preventative maintenance. Part III, Clean and Profitable, discusses how to set, meet, and keep track of clean energy and sustainability measures across the supply chain.

HEAT RECOVERY

Heat recovery from gas compression

When gas is compressed, some of the energy is inevitably converted into heat rather than pressure. "Recover Heat from Compressors," written by Ben Sliwinski and published September 20, 2011, in Sustainable Plant, discusses methods for recovering much of this heat for space and water heating inside the plant. The author shows that heat recovery from compressors can save energy and make financial sense, especially when planning begins early so that expensive retrofits can be avoided.

HVAC/R (Heating, Ventilation, Air Conditioning, and Refrigeration)

Chilled water system efficiency

"7 Steps to Optimizing a Central Plant" was written by Dave Klee, LEED AP, Johnson Controls; it was published in the August 2011 issue of HPAC Heating/Piping/AirConditioning Engineering. It shows that modern chilled-water plants lose efficiencies because they are not maintained as a unit, but as a series of separate components. The author presents seven steps which treat the entire chilled-water plant as a unified system. Each of the seven is described in useful detail.

Fan belt tension optimization

"Ensuring Proper Fan-Belt Tension," by Brian Mleziva, Greenheck Fan Corp., was published in the July 2011 issue of HPAC Heating/Piping/AirConditioning Engineering. It shows how to measure fan-belt tension so the tension is appropriate for the application, thus ensuring performance and long-life for both the fan and its motor. The focus of the article is on V-belts. The article includes a table showing recommended minimums for belt-deflections, another table showing recommended belt-tensioning slots and several illustrations.

PUMPS

Tips for efficient pump operation

Opportunities for increasing the energy efficiency of pump systems are discussed in "Don’t Overwork Pumps and Fans: Part 1," written by V. Venkatesan and published September 23, 2011, in Sustainable Plant. The article outlines steps for optimizing the energy efficiency of pump systems, including methods for switching to variable speed operation, identifying and eliminating double pumping, and others.

SOLAR ENERGY

Solar energy for metalworking

A pilot project being conducted at a German metal processing plant is using solar parabolic panels to create saturated steam. The pilot was designed to investigate the applications of solar parabolic steam for industrial uses, and so far the results have been encouraging. "Solar-Powered Metalworking," published September 13, 2011 at CleanTechnica.com, provides an overview. Further details can be found in "The Sunny Side of Saturated Steam" (published in German in 2011 by BINE Information Services).

Oregon winery powered by solar

Powers Winery/Badger Mountain Vinyard in Kennewick, Washington, recently installed a 2200 sq. ft. solar array to help power its winemaking and bottling operations. The array is expected to provide 18% of the winery’s energy needs, and should pay for itself in about four years. For details, see "Powers Winery, Vinyard Embraces the Sun," published September 3, 2011, in the Bellingham Herald.

NEWS

Training dollars for energy efficient manufacturing

On September 13, 2011, The U.S. Department of Energy (DOE) announced over $30 million in funding for the training of undergraduate and graduate level engineering students to conduct energy assessments in manufacturing facilities. As part of the training process, each university will complete about 20 energy assessments per year in local manufacturing plants. To learn more, read the DOE press release.

ITP State Activities website updated

The DOE Industrial Technologies Program (ITP) released an update to the State Activities website in September 2011. The site contains a plethora of statistics about industry, industrial energy use, and economic indicators for each state, and now includes an interactive map with details about state ITP activities, a comprehensive list of partner projects, and local contact information for industrial energy efficiency assistance.
