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

By Rod Smith, Compressed Air Best Practices® Magazine

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.

Fine Tuning Oil-Free Air Compressors and Purification at a Pharmaceutical Plant

By Don van Ormer, Air Power USA

A pharmaceutical product manufacturer spends an estimated $137,443 annually on electricity to operate the oil-free air compressors in its compressed air system. The compressed air system operates well and is providing the level of purification required.  Our team visited the plant and identified a group of projects which could reduce compressed air demand and reduce energy costs by $42,248 – or 31% of current use.

Compressed Air Savings with Nozzles or Blowers

By Jerry Zolkowski, P.E. CEM, Senior Engineer, Consumers Energy Business Solutions

Compressed air is used as a convenient and often necessary source of air flow to perform blow-offs, cooling, or drying.  And since compressed air is a costly utility, a frequent recommendation in this magazine and audits is to reduce the compressed air use by using high efficiency engineered nozzles. Using these nozzles is a good practice as they are designed in a way that uses the compressed air to accelerate the surrounding air to deliver the same mass transfer effect as a standard nozzle (or tube) with a much larger orifice.

Show Report: Compressed Air Technology at Record-Setting 2017 IPPE

By Rod Smith, Compressed Air Best Practices® Magazine

At a Midwest window manufacturing plant, the cooling process for the plastic frame pieces, after leaving the extruder, was critical to process productivity and quality. Too much cooling air (or not enough cooling air) would generate scrap and rejected product.

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

By Tim Dugan, P.E., Compression Engineering Corporation

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.

Low-Pressure Air Compressors Deliver Savings for Lafarge Cement Distribution

By Ron Marshall, Compressed Air Challenge®

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.
