Industrial Utility Efficiency

# Industries

The current cost to operate the compressed air system is \$139,100 annually, and the proposed measures will reduce it by \$50,700 annually. The proposed cost to complete the measures is \$47,600 providing a simple payback of 11 months. The cost included in the Action Plan includes engineering, project assistance, services to maintain the gains, and a 10% contingency.

## Small Piston Air Motors Save Big Energy While Ensuring Safety

Vane motors can run at much higher speeds (2000 rpm and up), but piston motors tend to turn much slower – less than 1000 rpm. For slower speed applications, vane motors are mated with a gear reducer and called a gearmotor. The gearmotor can produce the higher torque and slower speed needed for some applications, but the gear reducer can add some drivetrain loss. While a piston air motor may not be able to replace a vane motor where high speed is needed, it can be a good choice for high torque/low speed applications.

## Air Compressor Control Lessons Learned at Metal Products Company

Their system was designed and built to achieve premium performance, yet in a recent compressed air assessment the numbers showed their system had surprisingly poor performance, and worse, their staff was unaware of the problems. This article discusses some of the challenges faced and some future solutions that could get their system back to higher performance levels.

## DOE Better Plants Partners Get Serious About Compressed Air Systems

Compressed air is used in all the company’s plants and is often the single largest energy end use within them. As a result, compressed air energy-saving measures are often replicable across the company and offer significant positive impacts. One area of focus is with compressed air leaks since they are “the best low hanging fruit to focus on and they always keep popping up and waste energy”.

## Compressed Air System Design for Dust Collectors

The dust is collected on the bag or fingers, and when the cake of dust is of appropriate thickness and structure, a pulse or pulses of compressed air hits or shocks the bag and knocks the cake off. This pulse may sometimes be accompanied by physical shaking and even reverse air flows, depending on design.

## Metal Fabricator Measures Nitrogen Use, Receives a Surprise

Nitrogen is used in many facilities for a variety of purposes. The most common source of N2 is through the use of bulk liquid storage. A plant owner was recently surprised to learn that a large portion of his N2 was disappearing, without ever being used by his production process. This article discusses where it went and what we could do about it.

## Whiskey Distillery Compressed Air Study Saves Energy

A premium whiskey distillery was seeking to renew their compressed air system and meet their corporate mandate in making their production facility more efficient. The first step on the road to improvement was having their compressed air system assessed. This article discusses some of the findings of the system study, which saved significant energy, improved system reliability, and captured a significant utility incentive to help with the study costs and the cost of a new compressor.

## Why A Centrifugal Air Compressor May be the Better Choice

When selecting an air compressor for your manufacturing operation, the common choice is the industry-standard rotary screw compressor. Known as the work horse of compressed air machinery, the rotary screw compressor comes in a multitude of sizes and power levels. However, centrifugal compressors have seen some exciting technological progress in recent years and offer a wide range of pressures, flow and turndown. Long known for their longevity and durability, they offer higher efficiency, even qualifying for energy rebate programs offered by local utilities and all, notably, produce Class 0 oil free air.

## Three Ways To Make Packaging Lines More Sustainable

Sustainability is a high priority for today’s consumer packaged goods (CPG) companies. Driven by environmental responsibility, government regulations and customer preferences, CPGs are actively seeking ways to decarbonize their packaging lines and use eco-friendly packaging materials. Many have started monitoring the energy consumption of their equipment in real time and upgraded critical areas of their packaging processes using two key technologies: pneumatics and ultrasonic welding.

## Show Report: The 2022 International Production & Processing Expo

The 2022 International Production & Processing Expo (IPPE), was held January 25-27, 2022 in Atlanta with more than 500,000 square feet of exhibit space and 1,140-plus exhibitors. Attendee numbers had not been released when this was written. Sponsored by the U.S. Poultry & Egg Association, American Feed Industry Association and the North American Meat Institute, IPPE is the world's largest annual poultry, meat and animal food industry event of its kind.

Growing awareness of the importance of food grade lubricants for consumer safety and Hazard Analysis and Critical Control Point (HACCP) regulations, as well as increasing consciousness about Kosher and Halal registrations triggered an increasing demand for high performance food grade lubricants.
