Industrial Utility Efficiency

Technology

In late October 2023, professionals from around the world gathered at the Best Practices 2023 EXPO & Conference at McCormick Place in Chicago, Illinois to source and learn about Sustainable, Safe and Reliable On-Site Utilities Powering Automation including compressed air, blowers, vacuum, pneumatics, motors and cooling water systems. 

Pharmaceutical Deploys Flow-based System to Control Centrifugal and Screw Air Compressors

A large pharmaceutical company needed huge flow rates of 30 psig air to aerate multiple fermentation processes which create food-grade materials.  Flow could vary from about 12,000 scfm to 35,000 scfm.  There were a variety of batch processes, mostly running independently.  An hour-by-hour schedule for anticipated air flow is developed every afternoon for the next day.  Based on that schedule, the boiler operators run the air compressors that can handle the load range for the whole day. In reality, the peak flow can be higher than anticipated.

NMR Spectroscopy Lab Requires a -112°F Dew Point and Pure Nitrogen

Compressed Air Best Practices® Magazine interviewed Mr. Warwick Rampley, the National Sales Manager for Sydney (Australia) based, Basil V.R. Greatrex Pty Ltd.

It’s not every day one is asked to deliver a system able to provide both a reliable compressed air dew point of -80°C (-112°F) and high purity nitrogen.  We work with some excellent technology suppliers and have engineered a rather interesting system.  Although our firm was founded in 1919, this application is one of the most demanding we’ve encountered. Basil V.R. Greatrex is a unique company as we focus only on compressed air measurement, compressed air quality and compressed air efficiency.

Low-Pressure Air Compressors Deliver Savings for Lafarge Cement Distribution

The Lafarge Cement Distribution terminal located in Winnipeg, Canada has significantly reduced the site electrical demand and energy charges by changing the way they transport their cement.  Two new low-pressure rotary screw air compressors have replaced two large high-pressure air compressors that previously powered their dense phase transport system.  The resulting power reduction has saved the company 46 percent in transport operating costs.

Centrifugal Air Compressor Basics Part II - Understanding the Basic Performance Curve

A centrifugal air compressor operates over a range of flows and discharge pressures. The operating performance curve is shaped by the selected individual internal components and affected by operating conditions such as inlet pressure, inlet temperature, and cooling water temperature. The process of dynamic compression, as applied in a centrifugal compressor operating stage, is velocity and kinetic energy converted to pressure and temperature as the flow is restricted. Another term for this process is mass flow – the power requirement to deliver the rated cfm of flow at the rated pressure (psig) is determined by the weight of the air.

Regenerative Desiccant Compressed Air Dryers

Compressed air is dried to prevent condensation and corrosion which can disrupt manufacturing processes and contaminate products. Water is the primary promotor of chemical reactions and physical erosion in compressed air systems. A myriad of desiccant dryer designs have been devised to provide “commercially dry” air, air having a dew point of -40°F or less, to prevent corrosion.  Desiccant dryers use solid adsorbents in granule form to reduce the moisture content of compressed air.

Compressed Air Central Controller Delivers 5 KPI’s

Quite often the typical variability in compressed air flow demand does not proportionately translate into power reductions at the air compressors. This can be a result of numerous problems with the compressed air supply system. It is important to understand the supply-side’s ability to respond to the demand-side of the compressed air system. If the air compressors, on the supply-side, are not able to translate flow reductions into energy savings, implementation of demand reduction projects should be re-evaluated.

 

Permanent Compressed Air System Metering and Monitoring

Optimal compressed air system performance, defined by efficiency, reliability and air quality, has now become the main goal when operating, installing, purchasing or designing compressed air products. Whether you are the air compressor manufacturer, distributor or end user - everyone in the compressed air industry needs to be aware and work towards these goals.

BEKO USA Celebrates 25 Years

Earlier this year, BEKO Technologies completed the third renovation of its eight-year-old facility, which provided perfect timing for the company’s 25th Anniversary Event held on September 22, 2016 in Atlanta, GA.  The celebration marked 25-years of operating in the American markets after the German parent company, BEKO Technologies GmbH, first set up shop in the Tulsa, OK area in mid-December of 1990.  This important milestone was celebrated with a guided tour at the newly renovated American headquarters that included new product introductions and live demonstrations.

Selecting Purity Levels with Onsite Nitrogen Generators

The useful and various properties of nitrogen (N2) in industrial applications rank it as one of the most specified gases in industry. For the manufacturer, nitrogen options exist in the choice of delivery system, compliance with clean air standards, safety and purity. In researching these choices, manufacturers can accurately select the optimum nitrogen supply required, often at a considerable savings. Selecting purity levels of 99.99% or higher in many industries and applications ads a variety of costs, both financial and efficiency, which may be needlessly incurred.
