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.

Tate & Lyle’s sustainability actions involve countless initiatives worldwide to minimize its environmental impact by reducing emissions and using water sustainably. Whether it’s the use of a low-pressure blower instead of a high-pressure compressed air system to save energy, or a $75 million natural gas-fired Combined Heat and Power (CHP) system to replace coal as a power source at its corn wet mill in Lafayette, Indiana, Tate & Lyle is on a mission to protect the planet.

Medical

The air is delivered through a distribution piping system that ends with a medical air outlet within the room. Outlet requirements per room are governed by American Institute of America (AIA) Guidelines for Design and Construction of Hospitals and Healthcare Facilities. Equipment is plugged into the medical air outlet to treat the patient. Many studies have been done determining the load required for medical air compressors. The sizing can be calculated using several methods. 

Metals

Manufacturers familiar with the U.S. Environmental Protection Agency (EPA) ENERGY STAR® Energy Treasure Hunts initiative know it’s a great way to save energy and natural resources – as long as it’s done right – which is why some are turning to perhaps their best asset to achieve success: their unionized workforce.

Paper

The facility has a compressed air system consisting of four, 200-horsepower (hp) two-stage water-cooled lubricant-free reciprocating air compressors. The air compressors are controlled individually with local pressure switch controls connected to a common pressure sensing point. These air compressors have been operating since the mid-1960s and are very difficult and expensive to maintain because parts are scarce and service companies with experience servicing this type of air compressor are difficult to find.

This article is intended to show the relationships between risks and specifications, opportunities and responsibility in validation, and in particular, the use of modern and calibrated measurement technology in the sample chain.

Plastics

By making changes primarily focused on compressed air uses, Winpak, an international plastics products manufacturer based in Winnipeg, Manitoba, Canada, increased compressed air production capacity and reduced annual energy consumption by 33%. These benefits have been accomplished while the company was making the switch to lubricant-free compressed air to support product quality goals. This article discusses some of these changes and addresses measures that could be implemented in any compressed air system.

A newly constructed ethanol plant experienced control gap issues shortly after comissioning.  This article discusses the cause of the issue and how the problem was solved.

Printing

The Trinity Mirror Group print works on Oldham is one of the UK’s largest newspaper printers. The nine presses in the facility produce around 1million papers every day, including the Independent, the Daily Mirror and a range of local, regional and sports titles. Printing on this scale does not come cheap in energy terms, however. The plant’s annual electricity bill is in the order of £1.5millon. With energy prices on the rise, and a strong desire to improve environmental performance and reduce its carbon footprint, the plant’s management has recently embarked on a project to cut energy use substantially.

Transit

When the New York City Transit Authority (NYCT) set out to comply with local regulations calling for reductions in energy usage, it leveraged new air compressors for use in transit bus maintenance and repair – and took things to another level by recovering air compressor waste heat to provide hot potable water for the bus depot. The air compressor and heat recovery system, installed in spring 2017, is on its way to helping NYCT achieve the best energy savings possible.

Wastewater

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.
Power Smart® efficiency measures for compressed air systems at Tolko’s paper mill and sawmill at The Pas are saving the company more than $125,000 a year.  
Pneumatic air cylinders play a major role in allowing a modern sawmill to produce at the high-speed production rates required. Stable air pressure is critical to allow the air cylinders to respond in a timely manner and avoid any production delays.
Recently, this major pulp & paper mill made compressed air optimization a mill-wide priority. At the request of the utility company providing energy to the mill, Compression Energy Services performed a comprehensive energy analysis that outlined the following four energy efficiency measures (EEM’s) for the mill to consider.
“We are close to becoming a zero-landfill facility. Zero-waste is the goal,” Mike explained. Company literature on the Green Factory initiative, coordinated in North America by Karen Heyob, Associate Chief Engineer for Honda of America Mfg., Inc. , says the initiative is designed to reduce the impact of Honda’s manufacturing operations on the environment. This includes efforts to reduce the energy intensity of production, as well as initiatives to reduce waste generation, air emissions, and water use at all of the company’s manufacturing facilities in North America.
“First there are the old conventions. The majority of compressor houses still employ fixed speed compressors and a cascaded pressure switch control system. This arrangement will be familiar to many, but it is outdated and inefficient, and needs to be changed. There is a comfort factor with familiar technology, which is exacerbated by constant time pressure due to other day-today responsibilities and a lack of information and good advice on what can be achieved.”  
A Tier 1 automotive plant was spending $364,259 annually on electricity to operate their compressed air system. This figure was expected to increase as electric rates were forecasted to rise from their current average of 7.16 cents per kWh. Our firm, Air Power USA, conducted a full supply and demand-side compressed air system assessment. The set of projects recommended by the assessment, would reduce these energy costs by $218,670 or 60%.
The new paint specification, for Mercedes Benz Collison Repair Centers like Compact Kars, is for waterborne paints. “The new waterborne paints contain only two (2) pounds of volatile organic compounds (VOC) compared to 5.65 pounds per gallon of VOC’s present in solvent-based paints,” according to Mr. Elder. “For this reason, Mercedes Benz is asking all certified facilities to convert to waterborne paints.”
This automotive assembly facility has tremendous peaks and valleys in compressed air demand. Our audit using flow meters and pressure transducers with calibrated gauges has proven this. Our Phase 1 audit recommends the use of storage tanks and flow meters to reduce air consumption while stabilizing pressure.
Kneeling modules are quickly becoming the centerpiece of accessible vehicle equipment. This trend began with passage of the Americans with Disabilities Act (ADA) in 1991. Prior to the ADA, about 40% of all transportation vehicles were accessible to persons with disabilities.
We conducted a comprehensive compressed air system assessment. Opportunities to improve the system were found in the main piping system, in reducing pressure losses in the mold machine piping, and with the high ambient temperatures found in the compressor room. We estimated energy savings of 403,500 kWh per year for a power savings of $65,000 per year. The total projects costs were $48,000 for a simple ROI of nine (9) months.
