Synergistic capture mechanisms for alkali and sulfur species from combustion

Description: This report presents work done on a laboratory combustor in an attempt to identify mechanisms that govern the simultaneous capture of alkali and sulfur species using sorbent injection techniques. The mechanisms of capture fall into two broad categories i.e. Physical transport of alkali species (in vapor or condensed phase) to the sorbent surface and surface reaction between the alkali species and the sorbents. Water solubility, though not specific, has been used to get an indication of relative… more

(Study of flow properties of wet solids using laser induced photochemical anemometry)

Description: Research continues on the flow properties of wet solids. During this period we have made: progress in the analysis of the accuracy of the technique, progress in firming the foundations of LIPA for Solid-Liquid Mixtures, progress in the construction of better prototype skimmers, continued progress in chemically manufacturing both more red europium imbedded CaF{sub 2} and Green liquid Flowlite, and progress in understanding the coupling of LIPA chemicals snd dynamic range and timing.

Fundamental mechanisms in flue gas conditioning

Description: This project is divided into four tasks. Task 1 is the Development of a Management Plan. Task 2, Evaluation of Mechanisms in FGD Sorbent and Ash Interactions, focuses on the characteristics of binary mixtures of these distinct powders. Task 3, Evaluation of Mechanisms in Conditioning Agents and Ash, is designed to examine the effects of various conditioning agents on fine ash particles to determine the mechanisms by which these agents alter the physical properties of the ash. Tasks 2 and 3 bega… more

Supernatant liquid sampling in waste tanks

Description: Savannah River Site supernatant liquid waste samples are periodically taken and analyzed for corrosive and inhibiting species concentrations as part of the waste tank chemistry control program. These samples are taken at or near the surface of the waste. This is the preferred location for sampling since the liquid phase at this location is the most corrosive liquid phase in the tank as a result of the highest nitrate to nitrite ratio and the lowest hydroxide concentration. This report discusses… more

Compatibility of refrigerants and lubricants with motor materials

Description: During this last quarter, evaluations were complete on the motor materials after 500-hr exposures to refrigerants CFC-123, HFC-134a and HCFC-22 at 90{degrees}C. Materials were also evaluated after exposure to nitrogen at 127{degrees}C to determine effect of the thermal exposure. Other exposures were started during this quarter with refrigerants HCFC-124, HFC-125, HFC-143a, HFC-32 and HFC-152a. One 500 hr exposure is set up per week and one is analyzed the same week. This will enable Trane to co… more

Toroidal effects on drift wave turbulence

Description: The universal drift instability and other drift instabilities driven by density and temperature gradients in a toroidal system are investigated in both linear and nonlinear regimes via particle simulation. Runs in toroidal and cylindrical geometry show dramatic differences in plasma behavior, primarily due to the toroidicity-induced coupling of rational surfaces through the poloidal mode number m. In the toroidal system studied, the eigenmodes are seen to possess (i) an elongated, nearly global… more

HEME and HEPA filter element dissolution process

Description: High Efficiency Mist Eliminators (HEME) and High Efficiency Particulate Airfilters (HEPA) are to be used in the Defense Waste Processing Facility (DWPF) at the Savannah River Plant to remove volatile and semi-volatile effluents from the off-gases generated during the vitrification process. When removed, these filters are likely to contain radioactive contaminants, organics, and hazardous materials, which make their disposal by normal methods impractical. Hence, an alternative disposal method is… more

Establishment and maintenance of a Coal Sample Bank and data base

Description: During the period 7/9/92-10/8/92 a total of 80 samples (30 DOE Sample Bank samples and 50 other Penn State samples) of various sizes, not including DECS-17, were distributed. Fifteen of these samples were provided to DOE contractors. Six orders for a total of 80 30-gram bags of DECS-17 have been filled. All of these bags have been distributed to DOE dispersed catalyst contractors or those approved by DOE to receive the samples. A total of 188 data printouts were distributed. In addition, 15 spe… more

Calibration of the LAMPF E-960 polarized target

Description: This note is mainly about the offline corrections for the target polarization measurements of E-960. For the sake of minimizing the number of separate documents, I have also included my recent thoughts about the target constant, in Sec. 6. The E-960 data-taking was done in two separate runs. With respect to having an operative NMR system, the runs dated from 27-AUG-87 to 10-DEC-87 and from 14-AUG-88 to 6-OCT-88.These runs will be referred to as the ``1987`` and ``1988`` runs, respectively.

Fundamental studies of catalytic processing of synthetic liquids. Quarterly progress report, January 1, 1992--March 31, 1992

Description: This project revolves around understanding the fundamental processes involved in the catalytic removal of harmful oxygenated organics present in coal liquids. We are modelling the complex type of sulfided Mo catalyst proposed for these reactions with simple single crystal surfaces. These display a controlled range and number of reaction sites and can be extensively characterized by surface science techniques. We then investigate the reaction pathways for representative simple oxygenates upon th… more

Correlation of fracture toughness with impurity components. Final contract report

Description: This investigation was sponsored by the Los Alamos National Laboratory in an effort to understand better the phenomenon of stress assisted diffusion in cracked structures operating in corrosive environments. Work done on the extension of the existing ``Coupled Thermomechanical Diffusion`` theory to enable the prediction of diffusion of a solute species in stressed solids in the presence of cracks is presented here. Mathematical formalism is provided to support the intuitive notion that a singul… more

Vortex configurations in high-{Tc} superconducting films

Description: This article addresses the Ginzburg-Landau (GL) model for high-temperature superconductivity in thin films (two-dimensional periodic domains). A new gauge is defined to reduce the coupling between the equations for the nonzero components of the vector potential. The GL equations are written in a novel form by means of continuous link variables; this form is symmetric and has particular advantages for numerical analysis. The continuous GL model is approximated by a discrete model, which is shown… more
