By making sustainability a requirement and a core element of its growth strategy, Eastman has improved the energy efficiency of manufacturing operations by 13% since its baseline year of 2008 (the year Eastman became an ENERGY STAR® Partner). By 2018, Eastman had decreased its greenhouse gas intensity by 20%, two years ahead of its goal. Additionally, Eastman received the 2019 ENERGY STAR® Partner of the Year Award for Sustained Excellence, marking the company’s eighth consecutive ENERGY STAR award: two years as Partner of the Year and six years of Sustained Excellence recognition.
Products manufactured at the 100,000-square-foot plant in Kentucky include columns, I-shafts, covers, keylocks, and other dressings, along with shifter applications, such as straight, tap-up/tap-down and gated shifters. In all, the facility supplies automakers with products used in more than 100 different applications, all of which are designed keep vehicles operating safely, smoothly and reliably.
While many businesses strive to plan, install and maintain a compressed air system that fulfils the company’s specific needs, I’ve found that implementing compressed air best practices not only accomplishes specific goals, but also results in time-tested advantages that aid in the overall business and production goals of the organization.
There is usually a deep feeling of pride welling up inside the designers and installers after completing the installation of a new compressed air system, especially if it starts up and works perfectly. But what happens after a few years, are things as perfect as at the start? This is a question with an answer that very few people know for their system. This article describes some interesting experiences with a food products company at two plants where compressed air assessments of optimized systems done a few years after the system upgrades showed problems.
“A single ¼-inch leak in a compressed air line can cost a facility from \$2,500 to more than \$8,000 per year. Locating and fixing leaks will result in significant savings depending on pressure requirements and energy costs.”
One topic up for discussion in the metal fabrication industry is the assist gas used for laser cutting. The assist gas is fed into the laser head, and surrounds the laser as it cuts the work piece. The assist gas is intended to facilitate a smoother cut, increase cutting speeds and productivity, and to prevent discoloration, oxidation, scale, burred edges and other defects that can arise from the hot cutting temperatures. Since Nitrogen is an inert gas, it is used as an assist gas on many laser cutting systems to prevent oxygen from coming into contact with the metal while it’s being cut. Nitrogen is supplied to users in traditional cylinders, and with on-site nitrogen generation.
Outsourcing maintenance agreements for compressed air systems is commonplace in the food and beverage industry. The maintenance programs are often performed by air compressor distributors, who are experts in the specifics of the air compressors and compressed air systems they sell and service.
According to the United States Department of Agriculture, more than 30,000 food and beverage processing plants across the United States employ more than 1.5 million workers.1 Each of those plants applies a wide range of processes to raw agricultural goods to produce consumable food and beverage products.
A food processor was having compressed air problems, so they invited a compressed air auditor into their plant for an assessment and to help them size future permanent air compressors. The plant was experiencing low air pressure and detecting water in the compressed air lines despite having a desiccant air dryer. The auditor thoroughly analyzed the compressed air system production equipment and did end-use assessment and leakage detection. This article discusses the findings leading to a potential cost savings of 52% of the current level.
Blood plasma is an indispensable resource in the production of life-saving medicines. It is also in high demand on global markets. To make more efficient use of this valuable commodity, Biotest AG developed a new large-scale production plant in Dreieich, Germany, for plasma fractionation capable of obtaining five instead of the previous three products from a single liter of blood plasma. As part of its strategy, Biotest AG worked with Festo to standardize automation components used at the plant, resulting in simplified installation and maintenance.
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.
