Industrial Utility Efficiency

The basic function of vacuum degassing is to remove the vaporized gas and moisture from the extruded material. During the extrusion process, as raw materials melt under heat and pressure inside the extruder. The polymer chains and chemical compositions are going through changes, and a variety of gases are released.

Material Conveying with Pneumatic and Vacuum Systems

In many manufacturing operations, a very significant compressed air use is pneumatic conveying of many types of materials such as cement, fly ash, starch, sugar, salt, sand, plastic pellets, oats, feeds, etc. Often these are systems that use high-pressure air (100 psig class) reduced to lower pressures (15 psig, 45 psig). This creates an air savings opportunity.

A Kroger Company Bakery Saves Energy

Recently, The Kroger Company’s Indianapolis bakery identified the use of compressed air in a blow-off and conveyor gap transfer as a major source of energy loss and cost waste. According to the U.S. Department of Energy, “inappropriate use” of compressed air like blow-off produces high pressure atmosphere bleed leading to significant energy loss and unnecessary operational costs. Carrying a 10-15% efficiency return (according to the Department of Energy), compressed air applications can often be achieved more effectively, efficiently and less expensively with alternative solutions using a high flow rate and moderate pressure.

Water Treatment Plant Receives $1.7 million Energy Grant

A new cogeneration system installed at the Budd Inlet Treatment Plant by the LOTT (Lacey, Olympia, Tumwater, and Thurston County) Clean Water Alliance late last year uses treatment by-products as fuel to generate electricity and heat energy. This renewable energy system, combined with an aeration blower retrofit currently underway at the Budd Inlet Treatment Plant, is expected to save LOTT more than $228,000 per year in utility costs.

Blower Advancements for the Wastewater Industry

"The Numbers Don’t Lie". It’s a popular saying everyone has heard before, applied to a variety of situations – political statistics, figures backing up an athlete’s performance and budget data.

Thirty percent is a big number. Applied to the above scenarios, it could entail a landslide victory or a hitter gaining entry into the Baseball Hall of Fame. But just imagine, if the manager of a wastewater treatment facility were to trim 30 percent from their operating costs, he or she might also consider that a landslide victory of their own.

 

Wastewater Best Practices: Austrian Wastewater Plant is a Net Producer of Energy

Did you know that wastewater contains ten times the energy needed to treat it? Located near Strass im Zillertal, the Strass wastewater treatment plant (WWTP) serves 31 communities in the Achental and Zillertal valleys east of Innsbruck, Austria. It provides wastewater treatment for a population that ranges from approximately 60,000 in the summer to 250,000 during the winter tourist season, and has treatment requirements that include organic and nitrogen removal. An energy-independent facility, the plant produces more electrical energy than it requires for its operation.

 

Soft Drink Bottler Saves Energy With Blowers

A leading soft drink bottling manufacturer’s compressed air needs were threatening to exceed its Michigan plant’s compressed air capacity. Faced with the cost of buying a new compressor, the soft drink bottling manufacturer re-assessed their compressed air use to identify compressor and energy savings opportunities. In the audit, the soft drink bottling manufacturer identified the use of compressed air in a gap transfer as a source of compressed air and energy inefficiency.

An Introduction to WAGD System Implementations

This article will examine in detail four of the five acceptable WAGD implementations under NFPA 99, along with some alternative ways they may be implemented. This article will not deal with passive implementations.

Inappropriate-Use Assessment Saves 1,881 scfm

This factory currently spends \$735,757 annually on the electricity required to operate the compressed air system at its plant. The group of projects recommended in the system assessment will reduce these energy costs by an estimated \$364,211 (49% of current use). Estimated costs for completing the recommended projects total \$435,800. This figure represents a simple payback period of 14.4 months.
