A Novel Method for the Removal of Trace Concentration of Elemental Mercury From Utility Emissions

Description: A new technique for removal of elemental mercury from emissions of coal-fired utilities was investigated. The key idea is to selectively photo ionize the mercury atoms. A strong electric field gradient then drags them to the negative plate where they can be collected and removed.

A TECHNICAL, ECONOMIC AND ENVIRONMENTAL ASSESSMENT OF AMINE-BASED CO2 CAPTURE TECHNOLOGY FOR POWER PLANT GREENHOUSE GAS CONTROL

Description: Capture and sequestration of CO{sub 2} from fossil fuel power plants is gaining widespread interest as a potential method of controlling greenhouse gas emissions. Performance and cost models of an amine (MEA)-based CO{sub 2} absorption system for post-combustion flue gas applications have been developed, and integrated with an existing power plant modeling framework that includes multi-pollutant control technologies for other regulated emissions. The integrated model has been applied to study t… more

MONITORING POWER PLANT EFFICIENCY USING THE MICROWAVE-EXCITED PHOTOACOUSTIC EFFECT TO MEASURE UNBURNED CARBON

Description: Three test instruments are being evaluated to determine the feasibility of using photo-acoustic technology for measuring unburned carbon in fly ash. The first test instrument is a single microwave frequency system previously constructed to measure photo-acoustic signals in an off-line configuration. This system was assembled and used to begin testing parameters thought to be influential in the resulting photo-acoustic signal output. A standard modulation frequency was chosen based upon signal t… more

ADVANCED FLUE GAS CONDITIONING AS A RETROFIT UPGRADE TO ENHANCE PM COLLECTION FROM COAL-FIRED ELECTRIC UTILITY BOILERS

Description: The U.S. Department of Energy and ADA Environmental Solutions are engaged in a project to develop commercial flue gas conditioning additives. The objective is to develop conditioning agents that can help improve particulate control performance of smaller or under-sized electrostatic precipitators on utility coal-fired boilers. The new chemicals will be used to control both the electrical resistivity and the adhesion or cohesivity of the fly ash. There is a need to provide cost-effective and saf… more

RECOVERY AND SEQUESTRATION OF CO2 FROM STATIONARY COMBUSTION SYSTEMS BY PHOTOSYNTHESIS OF MICROALGAE

Description: Most of the anthropogenic emissions of carbon dioxide result from the combustion of fossil fuels for energy production. Photosynthesis has long been recognized as a means, at least in theory, to sequester anthropogenic carbon dioxide. Aquatic microalgae have been identified as fast growing species whose carbon fixing rates are higher than those of land-based plants by one order of magnitude. Physical Sciences Inc. (PSI), Aquasearch, and the Hawaii Natural Energy Institute at the University of H… more

Energy payback and CO{sub 2} gas emissions from fusion and solar photovoltaic electric power plants. Final report to Department of Energy, Office of Fusion Energy Sciences

Description: A cradle-to-grave net energy and greenhouse gas emissions analysis of a modern photovoltaic facility that produces electricity has been performed and compared to a similar analysis on fusion. A summary of the work has been included in a Ph.D. thesis titled ''Life-cycle assessment of electricity generation systems and applications for climate change policy analysis'' by Paul J. Meier, and a synopsis of the work was presented at the 15th Topical meeting on Fusion Energy held in Washington, DC in … more

INTEGRATED SYSTEM TO CONTROL PRIMARY PM 2.5 FROM ELECTRIC POWER PLANTS

Description: The initial round of Advanced ElectroCore performance tests was conducted at what LSR believed to be the best test condition. Most of the data were taken with the unit running at a specific separating area (SSA) of 100 ft{sup 2}/kacfm and a bleed flow ratio of 10 percent. Some data were taken with the separator electrode energized and some without energization. Analysis of the data from the first two set of tests showed that there was probably an optimum electrode voltage to produce a maximum e… more

Carbon reduction emissions in South Africa

Description: This project is a feasibility study for a control system for existing backup generators in South Africa. The strategy is to install a system to enable backup generators (BGs) to be dispatched only when a large generator fails. Using BGs to provide ''ten minute reserve'' will save energy and reduce emissions of greenhouse gases by an estimated nearly 500,000 tons of carbon dioxide per year.
