Abstract: In early 1989, Central Power and Light Company received a request from the Coastal Corporation to wheel power from an affiliate (Coastal Refining) cogeneration facility to 28 remote installations owned by other affiliates. CPL then requested through Docket No. 8650 that the PUCT review the applicability of certain parts of the wheeling rules, and in April the Commission appointed a task force composed of representatives from affected industries, utilities, and regulatory staff to review the wheeling rules and suggest whether, or what, changes might be necessary. The task force expects to have final recommendations by the end of October.

Abstract: Meeting the Quality of Work-Life goals often involves programs that greatly increase the need for energy, such as providing large quantities of ventilated air during the heating season. This requirement by itself would increase total energy use by 20%. This seems contradictory to the corporate goal of 2% actual energy reduction per year, for the period of 1985 through 1990. However, integration of several concepts and utilizing waste energy from available sources provides the opportunity to meet and exceed both goals in a cost effective manner, with an excellent payback. The presentation quantifies the excess energy available, the equipment to utilize the energy, and the cost, savings, and payback data. Of particular interest is that the requirement of a 250% ventilation increase is met, and yet an actual total plant energy decrease of 23% is obtained.

Abstract: Industries have added sensitive electrical loads such as computers and electronic equipment to improve efficiency, lower costs and to raise the overall quality of the product being manufactured. With this new technology there is a requirement for a quality of power that has not been available by the electric utility. Sensitive loads cannot tolerate electrical disturbances such as harmonic distortions, overvoltage, undervoltage, momentary interruptions and transients that are inherent in the utility distribution system. The industrial customer turns to the power supplier to provide technical support, monitoring and assistance to upgrade the quality of power into the plant. Even though studies have shown only 20% of the problems identified are actually utility generated it is the responsibility of the utility to help the customer isolate and solve the problem. The motto of the Oklahoma Gas and Electric Quality of Power program is "If a customer perceives he has a problem, we have a problem." The commitment has been made to assist the customer until he is satisfied the problem is in fact solved.

Abstract: On/off operation and excess combustion air reduce boiler energy efficiency. This paper presents methods to quantify energy savings from switching to modulation control mode and reducing excess air in natural gas fired boilers. The methods include calculation of combustion temperature, calculation of the relationship between internal convection coefficient and gas flow rate, and calculation of overall heat transfer assuming a parallel-flow heat exchanger model. The method for estimating savings from changing from on/off to modulation control accounts for purge and drift losses through the boiler and the improved heat transfer within the boiler due to the reduced combustion gas flow rate. The method for estimating savings from reducing excess combustion air accounts for the increased combustion temperature, reduced internal convection coefficient and increased residence time of combustion gasses in the boiler. Measured boiler data are used to demonstrate the accuracy of the methods.

Abstract: In late 2004, Eastman Chemical Company’s Kingsport Site Utilities Division embarked on a project to investigate operations in one of the large refrigeration systems serving one of the process areas. The intent of this effort was to develop a methodical process to identify primarily behavioral or procedural opportunities to improve energy efficiency. A key component of this process was to put control plans in place to maintain any gains that were achieved. The project resulting in finding opportunities in both the supply an demand sides of the system that were worth on the order of 10% improvement in energy efficiency (MMBtu/klb produced). The project also developed control plans that included optimization routines to provide guidance for day to day operations.

Abstract: WHAT IS HUMIDITY? Humidity is water vapor in air. Water covers over two thirds of the earths surface. It affects everything we do in some way. Under normal atmospheric conditions water is the third largest component of air, but the amount of water in the air can vary widely. These factors make it very important to measure humidity in our environment. Because humidity has always been important many ways have developed to express the level of humidity. Probably the most common is the term RELATIVE HUMIDITY which is based on a combination of humidity and temperature. Terms based on humidity per unit weight or volume are PPM (parts per million), grains per pound, and others. Vapor pressure and dew point are measures of humidity alone. These are all terms used to quantify the question how humid is it?

Abstract: The overall goal of the DOE Industrial Heat Pump Program is to foster research and development which will allow more efficient and economical recovery of waste energy in industry. Specifically, the program includes the identification of appropriate heat pump applications within the industrial sector and the subsequent development of heat pump technologies to meet the industrial requirements. The initial phases of the program were directed towards extending the technology of the more conventional heat pump systems, such as, Rankine and Brayton cycles so as to provide near-term results. In addition to system studies, material and component developmental programs were undertaken that would potentially result in enhanced performance and reduced costs. Research in more sophisticated and higher risk heat pump systems are being pursued on a longer term schedule. Novel mechanical systems, such as sterling cycles and magnetic heat pumps and advanced chemical systems, such as zeolite-water absorption cycles and heat of reaction systems are currently being investigated. This paper provides the program rationale and details the logic employed in designing a sound and cost-effective R&D program. A R&D flow diagram is structured with a series of major milestones or go/no go decision points. The paper traces the systematic progress of a technology from conception, through the various developmental phases until final prototype tests.

Abstract: Radiance Services Company manages a new technology called the Radiance Process®, a dry non-toxic technology for surface cleaning. The Radiance Process received the National Pollution Prevention Roundtable's 1997 Most Valuable Pollution Prevention Award. It employs quantum mechanical effects of laser light and a flowing inert gas, ordinarily nitrogen, to clean surfaces. The light lifts the contaminant from the surface and the flowing gas sweeps it away. There is no pollution and no waste besides the removed contaminant itself. The Process is inexpensive and readily adaptable to many manufacturing products ranging from computer chips, hard disks, and night vision goggles to tire molds. The Process is covered by 29 patents issued in the U.S. and overseas and 189 patent applications pending internationally.

Abstract: Electro-Magnetic Energy has finally made its way into the Petro-Chemical market twenty-five years after market acceptance in the Food Processing Industry. Major factors influencing this change are tighter environmental regulations, price competition and increased production requirements. The main barriers are primarily due to perception of high costs and safety issues coupled with the fact that neither industry had a strategic reason to market their products to each other. The speed at which these changes can take place is impeded by the lack of industry information sharing brought on by the need to gain a competitive edge. These barriers are beginning to break down now that the Petro-Chemicals engineering and management are requiring their processes be reviewed to meet the challenges.

Abstract: Comparisons are made of the performance and installation costs of Rankine and Brayton power cycles when applied to waste heat recovery from a 350 ton/day container glass furnace. The power cycles investigation included: a) a conventional steam Rankine cycle, b) an organic Rankine cycle, c) an indirectly heated positive pressure Brayton cycle and d) a directly heated subatmospheric Brayton cycle. For the specified flue gas temperatures considered, the organic Rankine cycle produced the most electric power. If, however, reduction in fuel cost is of primary importance, then simple heat recuperation is the most effective method of heat recovery. Except for the subatmospheric Brayton cycle, typical payback periods are on the order of three to four years. The subatmospheric Brayton cycle was found not to be an attractive heat recovery alternative for this particular application.

Abstract: Combined Heat and Power (CHP) has been identified as a significant opportunity for greater energy efficiency and decreased environmental impacts of energy consumption. Despite this, the regulatory and policy landscape for CHP is often quite discouraging to the deployment of these systems, despite their many benefits to customers and society at large. That the landscape changes considerably from state to state only confuses the matter. Of all the various types of distributed generation, CHP systems encompass technologies particularly hard hit by policies and regulations that do not actively support their deployment. Given the large size of some CHP systems, interconnection standards that clearly delineate interconnection processes for multi-megawatt systems are necessary. In addition, since many CHP technologies emit incremental criteria pollutants as part of their operation, the manner in which emissions are regulated by a state can significantly impact the financial realities of running a CHP system. In the absence of strong federal guidance, interconnection standards, tax incentives, tariff designs, environmental regulations and other policy measures that dramatically impact the attractiveness of CHP projects can only be significantly addressed by state lawmakers and regulators. State activity is essential to creating a policy framework that encourages CHP. Within the past several years, a number of states have made significant strides in implementing more “CHP-friendly” policies. Some states have worked to develop these policies at an accelerated rate while others have done little. In many cases the difference between states that are proactively encouraging CHP and states that are ignoring it all together is stark. This paper will identify which states are leading the way, which states are following, and what the policies of all states look like at this current point in time. It will define what “CHP-friendly” policies are, what makes a good policy better, and discuss the manners in which a variety of states have chosen to approach CHP. CHP system developers will come away with a clearer picture of each state’s unique CHP barriers, potential CHP customers will understand how their current CHP climate compares to that of other locations, and state lawmakers and CHP advocates will be able to learn about best practices in policy creation that already exist in the field.

Abstract: Until the present there has been no effective way to rapidly scan thermally insulated refinery or process piping for corrosion or thin wall. Such defects, if left unattended, can lead to wasteful losses of time, energy and money. To date the most common means of locating such defects has been random spot measurement of suspect regions using ultrasonic or radiographic techniques. The obvious weakness of such an approach is the low probability of selecting the region of most severe corrosion in a long expanse of insulated piping. PA Incorporated has developed an electromagnetic inspection device which rapidly scans nearly 100 percent of an insulated pipeline (flanges and tees excluded) and provides a quantitative (2 percent) measurement of average wall thickness and qualitative evaluation of external and internal corrosion. The value of the device lies in its ability to quickly locate major problem areas through thermal insulation which can then be examined in more detail by removing insulation and using other techniques. This paper describes the device, the inspection results to date, and the unique advantages of this new inspection tool.

Abstract: This paper considers three related questions: 1) What are the primary economic driving forces which determine the rate of industrial energy conservation? 2) How much industrial energy conservation has been achieved over 1972-1973 levels? 3) What are the goals and expectations for decreases in industrial energy use during the next 10-20 years? The specific energy consumption (SEC) of a plant or industry, measured in BTU of fuel used/ton of product produced, can be used to monitor the energy conserved. The rate of SEC reduction is a function of five primary variables: the potential for reduction of the SEC, the unit cost of fuel, the capital available for implementation of conservation measures, the quantity of fuel available, and the availability: of equipment to implement needed conservation measures. A mathematical-economic model is proposed for the decrease in energy use, and permits calculation of dollars saved also. Conclusions from the study are: 1) Potential savings were estimated as 20-31% of 1972 levels; through 1978 a 13-20% actual reduction in energy use has been achieved. 2) The additional can be realized by; 1982 by "strong action", or by 1987 by "moderate action". To date moderate action has been taken. 3) Overall energy conservation pays out rapidly - dollars saved return dollars invested many fold!

Abstract: Through its Industries of the Future (IOF) strategy, the US DOE's Office of Industrial Technologies (OIT) seeks to develop and deploy advanced technologies and practices that will increase energy efficiency, environmental performance, and productivity for manufacturers in nine energy-intensive and waste-intensive industries. OIT helps establish state IOF Partnerships in order to expand the benefits of the national IOF strategy to many manufacturers on the local level. By supporting an IOF Partnership, states mitigate factors that inhibit effective response to challenges faced by their industries and also provide a coordinated framework for state-level industrial programs. The state optimizes its intellectual capital by coordinating efforts of universities, industrial leaders and state officials. The resulting benefits are especially evident in the areas of environmental policy and economic development.

Abstract: A Tie Line Control System maintains the purchase quantity of electrical energy an industrial facility buys from a utility company. Implementing an advanced Tie Line Control system automates the buy versus make decision process for an industrial facility in order to optimize the use of energy by either a supply-side method or a demand-side method. If a facility possesses supply-side resources, such as self-generation, the user can choose to maximize on-site energy generation, when it is less expensive than the price offered by the utility. Conversely, when the price to buy energy is less expensive than it is to produce it, a facility may choose to back off on self-generation and buy more energy. One such Advanced Tie Line Control system, designed by Automation Applications, Incorporated (AAI) and installed at a pilot facility, utilizes a real-time pricing utility contract and provides savings approaching one million dollars per year. This paper is a case study of this system implementation and the results achieved.
