Industrial Utility Efficiency

System Assessments

We asked a hand-selected list of original equipment manufacturers, independent compressed air system sales and service companies, manufacturing plants and independent system auditors to share their thoughts, highlighting the changes they’ve seen over the past 20 years, then predicting what the next 20 years will bring.

An Automotive System Assessment

This stamping plant is a 2.5 million-square-foot facility with over two thousand employees.  At the time of the assessment, the plant was processing approximately 1,600 tons of steel per day into automotive vehicle components and parts such as body parts.

Seven Sustainability Projects: Air Compressors

Reducing energy costs and pollution emissions involves many areas within an industrial facility.  My studies have found seven (7) key (or common) areas where low cost practical projects can be implemented.  Combined, these projects provide savings exceeding 10% of the annual energy spend with an average payback of less than one year.

A Food Processing System Assessment

This facility processes bulk food ingredients into finished packaged food products. The factory belongs to a division of a large corporation and was spending \$732,342 annually on energy to operate their compressed air system. This system assessment detailed twelve (12) project areas where yearly energy savings totaling \$214,907 could be found with a minimal investment of \$68,350. Due to space constraints, this article will detail only the higher impact project areas. The over-all strategy for improving this air system centers on improving specific power performance of the #3 centrifugal air compressor and reducing over-all demand with compressed air savings projects.

Assessment Improves Electroplater Production

Faced with rising energy costs, a large electroplating company sought to improve the efficiency and reliability of its compressed air system. After getting a quote from their vendor on a new 300-hp compressor to replace an existing unit, the company sought a comparison quote due to the significant investment the new compressor represented. Based on a recommendation from one of their customers, they turned to Scales Industrial Technologies.

Explosion-Proof Vacuum Systems for Combustible Dust

In February of 2008, a sugar plant near Savannah, Georgia suffered the ultimate tragedy. Fouteen employees were killed and 40 injured when finely ground motes of sugar dust ignited, setting off a violent blast. If the fatalities and a tarnished reputation weren’t enough, the Occupational Safety and Health Administration (OSHA) then fined the company more than 8 million dollars in workplace violations related to combustible dust.

ISO 8573.1 – Contaminants and Purity Classes

Industry standards serve a very important purpose for the end users of compressed air equipment.  If the standards are well written, they can help to promote the equipment that they govern, as long as the equipment manufacturers properly apply and promote the standards.

Boiler Soot-Blowing in Power Plants

Utilities have been cleaning their boilers for many years using either steam or high-pressure air.  In the past, when air was used, due to the size of the boilers and the reasonable quality of fuel used, a relatively small amount of cleaning was required.
