Industrial Utility Efficiency

Technology

Conventionally when we talk about oil lubricated screw air compressor maintenance, it is mostly about replacing consumables such as filters and lubricant on time. While these consumables have a defined usable life and have a direct effect on the efficiency and the life of the air compressor itself when not replaced on time, there are a few critical valves in the air compressor that require maintenance as well. 

Understanding and Treating an Industrial Static Problem

In this article, we discuss problems associated with static electricity in industrial manufacturing operations and how to effectively address them. At the atomic level, materials have a balance of positively charged protons in the nucleus and negatively charged electrons in the shell. Balance requires the same number of each.  A static charge occurs when that balance shifts due to the loss or gain of one or more electrons from the atom or molecule. The primary mechanism for this loss or gain, among several possibilities, is friction.

Show Report: 2019 AEE World Energy Conference and Expo

The 2019 AEE World Energy Conference and Expo was held September 25-27 at the Walter E. Washington Convention Center in Washington D.C. The event featured 14+ tracks, 56 sessions, over 260 individual speakers, and 62 exhibitors.  Both Chiller & Cooling Best Practices and Compressed Air Best Practices® Magazines were pleased to be in the literature bins at the 2019 AEE World!

How to Keep Reverse Pulse Dust Collectors Operating Efficiently and Reliably

Reverse pulse type dust collectors often represent a challenge to compressed air energy efficiency, and sometimes throw a wrench into the works by causing huge air pressure fluctuations, high transient flows and just plain large leaks. This article discusses this type of dust collector, often installed in food processing plants, and gives some real-life examples of problematic installations. Some suggested measures are mentioned to ensure your dust collectors keep running in a trouble-free manner.

Integration: Should Compressed Air Monitoring be Combined with Control?

Maintenance is the customer of controls and energy engineering is the customer of monitoring. And I discussed potential problems that can occur when combining monitoring and control in the same system. In this article, I will get more specific about building practical systems that address both controls and monitoring.

Control Strategies for Efficiently Operating Multiple VFD Air Compressors

By far the most important development in the world of screw type air compressors has been the introduction of variable speed control using electronic variable frequency drives (VFD’s). Systems that run with at least one air compressor at part load can almost always operate more efficiently if a well-controlled VFD is added to the system. But what if a system has two or more VFD units? This article discusses the challenges in controlling multiple VFD air compressors with some suggested solutions.

Show Report: The 2019 AICD Conference & Exhibition

The members of the AICD (Association of Independent Compressor Distributors) send owners and senior management to the event. AICD member companies are independent companies selling and servicing air compressors in North America. “The AICD Board is pleased to announce we have added 18 member companies in the past year alone,” said AICD President Lisa Lewis (Michigan Air Solutions). “Vendor participation is at an all-time high as we’ve added 13 new exhibitors and special networking events for vendors to interact with AICD members.”

Fayetteville Wastewater Treatment Plant Lowers Operational Costs, Increases Efficiencies

The plant upgrades, in combination with a progressive management strategy, allows the plant to consume less energy and reduce its reliance on outside contractors for biosolids removal, resulting in total operational savings of approximately \$60,000 per year.  The plant is also positioned to efficiently manage the area’s wastewater for decades to come.

Don’t Overlook Tubing Volume with Manifold-Mounted Pneumatic Valves To Conserve Energy

The advent of manifold-mounted, plug-in pneumatic valves has been a boon for machine builders. It allows them to mount complete valve packages in a safe and secure location on a machine. Using a D-sub connector, serial interface module, or similar single-point wiring system, all of the electrical control outputs can feed into one location on the manifold, greatly simplifying the wiring.

The Hydraulic Air Compressor: An Old Idea Made New

The team is building on engineering concepts that were used to develop the first hydraulic air compressor at Dominion Cotton Mills, Magog, Quebec, Canada, over 100 years ago. The basic principles of the HAC were then used to produce compressed air at 17 locations worldwide, including the last at Ragged Chutes near Cobalt, Ontario, Canada, over 100 years ago.  This article discusses the development the HAC in this decade and the continuing work at Laurentian University, Ontario, to modernize the concept.
