Time Dependent Implementation of Argonne's Model for Universal Solvent Extraction

Oct 18, 2011
Kurt Frey
Argonne’s Model for Universal Solvent Extraction (AMUSE) simulates multi-stage aqueous solvent extraction processes for components of interest to spent nuclear fuel reprocessing. The current work has incorporated time dependency into the simulation; the original AMUSE program was used for steady-...

Evaluation of Alternative Fuels to Replace Coal In Cement Manufacturing

Oct 17, 2011
Steve R. Duke
A multiyear DOE-supported study was completed to identify, determine, and understand fundamental burn characteristics and properties of alternative fuel sources to replace coal for energy generation, with emphasis on impacts in cement processing. Portland cement manufacturing involves the...

An Osmotic Membrane Dehumidifier

Oct 17, 2011
Arthur S. Kesten
OSMOTIC MEMBRANE DEHUMIDIFIER It has long been known that relying on a vapor compression system to cool air down to the dew point in order to dehumidify is expensive to build and uses far too much energy to operate. The ability to dehumidify independently of cooling provides substantial advantage,...

Plasma Assisted Combustion for Environmental Applications

Mar 14, 2011
Young-Hoon Song
In the early part of the presentation, a detailed application of a plasma assisted combustor operated in a diesel exhaust line for regenerating DPF (Diesel Particulate Filter) are introduced. In this plasma assisted combustor, rotating arc is generated by a high voltage AC power and tangentially...

Resin Wafer Electrodeionization for Flue Gas Carbon Dioxide Capture

Mar 14, 2011
Rebecca L. Stiles
Energy efficient capture of CO 2 from coal-fired power plants is one of the grand challenges for the U.S. both to end dependence on imported energy and to reduce greenhouse gas emissions. Nalco Company and Argonne National Laboratory received a Department of Energy ARPA-E award to develop Resin...

Role of Plasma Chemistry In Fuel Reforming Process

Mar 14, 2011
Young-Hoon Song
The purpose of the present study is to investigate role of plasma chemistry in a fuel reforming process. So far, role of plasma chemistry in a fuel reforming process has been a controversial issue, since coupling of plasma chemistry and thermal chemistry in fuel reforming process is inevitable...

Design Enhancements of a High Temperature, Ceramic Micro-Channel Heat Exchanger

Nov 9, 2010
Merrill Wilson
The recent developments in the energy and process industries have lead to more efficient, higher-temperature processes and compact equipment. By using small features such as micro-channels, pin fins or plate fins the length scale for which transport occurs is minimized and thus increases the heat...

Fouling Monitoring Techniques for Water Treatment Membrane Processes

Nov 7, 2010
Kuo-Lun Tung
Membrane fouling and flux decline are undesirable, albeit inevitable, problems in membrane filtration processes for water treatment. The development of low fouling membranes, the design of high efficiency modules, the selection of optimal operational strategies, and several improvements made in...

Hydrogen Production by Reforming of Logistic Diesel Fuel in Supercritical Water

Mar 23, 2010
Carsten Cremers
Compared with other fuels, diesel fuels still have significant advantages in terms of logistic properties such as energy density, availability and ease of handling. However, diesel fuels also have their draw backs. For an example, the only established technology to convert the chemical energy of...
