Abstract: If your company is looking at energy management as part of its overall strategy to reduce costs and improve profits, it is not alone. While energy prices have increased at a shocking rate, so has interest in environmental responsibility. Progressive organizations are exploring ways to conserve energy and reduce greenhouse gases. Some are even creating new positions for these issues, placing someone in charge of corporate social responsibility (CSR). The CSR's job is to help a company be more socially responsible and reduce harmful emissions. Energy management can accomplish both conservation and emission goals- plus, it lowers utility costs and strengthens your bottom line! In the past, reasonably priced energy made it difficult to justify new conservation projects. It was hard to meet the standard criteria of 2-3 years payback. However, natural gas prices have tripled in the last five years from $2 to over $6 per Dekatherm (Dth). Electric prices also have increased dramatically-by more than 100% in some parts of the country. These increased energy costs have made conservation projects more desirable. A natural gas improvement project that had a six-year payback five years ago may have less than a two-year payback today. New technologies also have helped drive down the payback of projects and opened up new areas for potential savings. The following paper looks at how the new market offers opportunities to reduce overall energy costs.

Abstract: In January 1994, 3M began the task of optimizing the electric motor systems at 3M Center, a 26 building, 7 million square foot corporate campus. A cross-functional, cross-company team was established which included four 3M employees representing two different departments within 3M, an engineer specializing in demand side management programs from Northern States Power Company, and a sales engineer from General Electric Supply Company. The team was later joined by an engineering specialist from Landis & Staefa, Inc., a building automation controls supplier. The team began the task of identifying the projects that could save energy and provide a reasonable return on 3M's investment on a building by building approach. As surveys were completed, proposals were prepared and presented to management requesting funding. The team continued the process of identifying projects in remaining buildings and took on the responsibility of designing, contracting and implementing projects as funding was approved for those already studied. Follow-up measurements to ascertain that the savings predicted was actually achieved are done before project close-out. This project was submitted and accepted as a Motor Challenge Showcase Demonstration Project. The Motor Challenge is a U.S. Department of Energy initiative to promote the efficient use of energy in electric motor systems. Showcase Demonstration Projects are used to exemplify the benefits that motor system optimization can provide. This Showcase Project is different from most as it emphasizes the process that was developed to carry out a project of this magnitude rather than any single specific technologies or applications. The team has completed the project at 3M Center. Measured savings are $823,000 per year. This paper will discuss the Motor Challenge Showcase Demonstration project that was completed at 3M Center, the motor systems survey methodology the team developed, analysis tools and techniques and the results that have been attained.

Abstract: Economic industrial heat pumping to temperatures above 500°F (260°C) is promised in the near future. A new absorption fluid is the key. Tested under DOE sponsorship, the new fluid has proven to be thermally stable and noncorrosive to austenitic stainless steel up to 500°F, or mild steel up to 430°F. Heat transfer properties are comparable to those of the conventional LiBr-H20 system. Paired with water as the working fluid, laboratory tests have shown that useful temperature lifts of over 162°F (90°C) ∆T can be achieved allowing 10°F heat exchangers. The fluid is nontoxic and noncombustible. Good economics for the system should stem from (1) high temperature capabilities for wider and more highly valued uses, (2) high internal temperature lifts for low heat exchanger surface areas, (3) predominantly carbon steel components, and (4) better COP in the heat amplifier mode than current absorption heat pumps. Recent laboratory results are presented including temperature applicability maps.

Abstract: The absorption cycle offers one of the most economic and widely applicable technologies for waste heat upgrading. It can use off-the-shelf hardware that is available now, at any required capacity rating. Fractional distillations, as a class of applications, embody characteristics that inherently make them economic candidates for absorption cycle heat upgrading. Practical applications to current U.S. distillations could save 30 trillion BTU per year, at payback periods ranging from 1 to 3 years. So, if the absorption cycle is so great, why isn't it more in use? There are three reasons: (1) lack of understanding of the basic principles and operation; (2) lack of guidelines for readily identifying attractive applications, and (3) lack of a commercial U.S. demonstration in the highly cost-effective distillation area. This paper presents absorption cycle fundamentals and applications guidelines, and announces a government-backed search for a site for commercial demonstration of the distillation energy savings. The guidelines provide a new tool for identifying attractive absorption cycle applications. They require only knowledge of process source and sink temperatures, and they show at a glance approximate component characteristics and payback period for the absorption cycle which would serve the application.

Abstract: The concept of a thermal powered absorption heat pump is not a new or revolutionary idea. It has been successfully demonstrated in the lab and prototypes have been installed in the field. Units have been successfully applied in a number of industrial and commercial installations. Even more has been written about absorption heat pumping and many presentations have been made at energy symposiums and technical seminars. In fact, there have been more written and spoken words about absorption heat pumping than actual field installations. If absorption heat pumping is so great, then why haven’t more end users elected to take advantage of the benefits of absorption heat pumping? In this paper we will look at various types of absorption heat pumping and the associated economics and performance characteristics. We will also discuss some possible reasons why the absorption heat pumping concept, which looks great on paper, has yet to find a sustained niche in the industrial marketplace. And lastly, we will discuss some possible steps that could be taken by all parties to make absorption heat pumping a truly visible and viable alternative for conserving energy and reducing energy costs.

Abstract: When the heat source available to a distillation process is at a significantly higher temperature than the reboiler temperature, there is unused availability (ability to perform work) in the heat supplied to the reboiler. Similarly, if the reflux condenser operates above ambient temperature, the rejected heat also contains unused availability. By incorporating an absorption heat pump (AHP) into the distillation process, these sources of unused availability can be tapped so as to recycle (and hence, conserve) up to 50% of the required distillation energy. In contrast to compressor driven heat pumps, this savings is accomplished without need for a separate substantial input of mechanical power. A different AHP configuration is used depending on whether the excess availability is in the source heat or reject heat. In the excessive source temperature case, the higher temperature source heat is applied to the AHP, which then supplies the total reboiler requirement and recycles half the reject heat, with the remainder being rejected conventionally. In the excessive reject temperature case, all the reject heat is supplied to a reverse absorption heat pump (HAHP) which recycles half to reboiler temperature while reducing the remainder to ambient temperature.

Abstract: Energy management is dependent on the ability to accurately measure all energy sources so controls can take place. A survey fifteen years ago in Great Britian showed that the primary elements used for flow measurement of steam and gases were square law devices, with limited turndown and high sensitivity to velocity profile. This showed the need for a primary device able to give accurate readings over a wide turndown; long life handling hostile fluids; presenting the fewest possible installation problems. A variable differential pressure device producing a differential directly proportional to flow rate is the result.

Abstract: Over 100,000 electric motors drive the production equipment throughout a large chemical company. The energy-efficiency and reliability of these motors during their entire life have a decided impact on the company's manufacturing costs and production capability. The Corporate Motor Technology Team (CMTT) conceived and led a program to optimize the cost effectiveness and reliability of new motors and developed criteria to determine whether to repair or replace motors that fail. The higher energy efficiency of the electric motors offered by vendors today plays a crucial role in these decisions. The company's current motor specification, procurement, maintenance, repair and replacement practices are vastly improved and consistent across the corporation. The 1995 savings attributed to the higher energy efficiency of over 2000 motors installed the prior year amount to $570,000 and will continue to accrue year after year. So will the savings stemming from lower maintenance cost and reduced downtime.

Abstract: After years of attempting to streamline operations in an effort to reduce operational costs, many industrial manufacturers are turning to strategic energy management as a potential money-saving strategy. In their efforts, managers face a number of significant barriers such as low awareness and expertise, elevated financial hurdle rate, lack of capital allocation and procurement constraints. In addition, energy efficiency efforts may be hampered by traditional single point energy reduction methods such as reviewing utility bills, getting equipment upgrade suggestions from vendors or one-time energy audits. Research demonstrates that these techniques have neither the visibility nor continuity to achieve energy reductions that are consistent and persistent. With the right Best Practices, however, using new methodologies and technologies unavailable only a few years ago, enterprises can achieve dramatic energy reductions and their resulting cost savings. These Best Practices are founded on 1) application of a systematic methodology for understanding where energy is used and how to reduce it; and 2) achieving visibility into sufficiently granular real-time information on key performance indicators; 3) integrating new technology into overall corporate strategy and processes to change behavior.

Abstract: Large amounts of sodium sulfate are produced as a by-product of many diverse industries. Some of this material is recycled internally. Some is upgraded and sold as a product. Most is disposed of as waste in landfills, or discharged to deep-wells, or bodies of water. Electrolytic regeneration of by-product sodium sulfate can profitably exploit this valuable internal resource. ELTECH has a proven record in the development of long-life anodes for use in acid sulfate solutions, and in providing high performance electrolytic generators.
