Industrial Energy Savings    

System Assessment

Since the cost of energy has dramatically increased during the past few years, it seems that energy audit companies have opened shop on more city street corners than coffee shops in Seattle.  In addition to the mass numbers and abundant varieties of these energy savings promoters, there have been an equal number of energy audit articles written for the engineering magazines.  

Compressor Controls

Roxane Laboratories, Inc., a subsidiary of Boehringer Ingelheim Corporation located in Columbus, Ohio, created a world-class air system that generated $61,314 per year in electrical energy cost savings (1,156,868 kWh), improved productivity and quality, and allowed the successful completion of a significant plant expansion.

Piping Storage

Perhaps your facility recently had a compressed air system survey, conducted by an air systems services company, that resulted in a couple of major recommendations, such as:  • Install a new smaller compressor and new control systems on all of the units • Repair the many air leaks (identified as 30% of your system capacity)  

End Uses

A basic element in the Compressed Air Challenge® (CAC) philosophy is that compressed air system optimization should be addressed using the “Systems Approach”. This method recognizes that improving and maintaining peak compressed air system performance requires addressing both the supply and the demand sides of a system and understanding how the two interact. “The road to energy efficiency involves more than just fixing the leaks,” says Ross Orr, an experienced auditor with Scales Industrial Technologies and a certified CAC instructor.

Pressure

The Compressed Air Challenge® (CAC) is a voluntary collaboration of industrial users; manufacturers, distributors and their associations; consultants; state research and development agencies; energy efficiency organizations; and utilities. This group has one purpose in mind - helping you enjoy the benefits of improved performance of your compressed air system. The mission of the Compressed Air Challenge (CAC) is to provide resources that educate industrial users about optimizing their compressed air systems.

Air Treatment/N2

The facility is a plastics injection blowmolder and is a division of a large corporation. The following information was produced from a compressed air system assessment done over seven days in 2008.

Leaks

Understanding the supply side of the system is important, but more important is first looking at compressed air demand. One demand that is consistently in need of attention in industrial facilities is the air flow caused by leaks.

Pneumatics

When it comes to conserving energy in compressed air nothing is sexier than a big, old, oil-free 300 horsepower variable speed drive air compressor coupled with a heat of compression dryer tied to an energy management system with all the trimmings. If you’re like me, it’s hard not to let out a manly grunt after reading that sentence.

Vacuum 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.
A comprehensive compressed air system analysis should include an examination of both air supply and usage and the interaction between the supply and demand. Auditors typically measure the output cfm of a compressed air system and the input kW, calculate energy consumption in kilowatt-hours, and determine the annual cost of operating the system. The auditor may also measure total air losses caused by leaks and locate those that are significant.

With energy cost increasing at 7.5% per annum for the past few years, most facilities managers and maintenance professionals are looking for the best opportunities for excellent return on investment projects, which can drive their operating costs in the opposite direction. Compressed air is an area where significant improvements are readily available.
Large hospitals often use compressed air for important operational related end uses. The systems that produce this air need to supply clean and dry compressed air with a high level of reliability. These systems are not immune to efficiency problems as is the case for any compressed air system.
There is an enormous population of vacuum generators being used successfully by industry. Applications range from pick & place to vapor extraction to bulk material handling and the number of installations is growing. Before proceeding with an installation utilizing these devices, there are two general issues to consider: efficiency and appropriateness.
The roots of our company start with my father, Jan Dekker, who was heavily involved with oil-sealed liquid ring vacuum systems used in the gold mines of South Africa. This was in the mid-1970’s when gold prices were going up. Vacuum systems (in the mines) were optimized by improving vacuum levels using oil instead of water and by adding vacuum boosters.
Sitting on his desk the day Brian began his new job as Plant Engineer for Carbo Ceramics’ McIntyre, GA facility was a proposal to purchase a new 150 HP air compressor as a backup machine. The facility already had six of these machines and, yes, all six ran almost continuously.
Swiss brush company Ebnat-Kappel uses non contact transfer technology from Bosch Rexroth to automate a problematic section of its packaging production process.
