Geothermal waste treatment biotechnology: Progress and advantages to the utilities

Description: Development of biotechnology for treatment of geothermal residual waste is aimed at the application of low-cost biochemical processes for the surface treatment and disposal of residual geothermal sludges. These processes, in addition to the lowering of disposal cost, are designed to be environmentally acceptable. Recent studies at Brookhaven National Laboratory (BNL) have shown that optimization of several process variables results in fast rates (<24h) of metal removal from residual sludges at … more

Investigation of Celotex trademark charring depths in the DT-18 shipping container

Description: Celotex {trademark}, the insulating material used between the outer and inner containers of the DT-18 shipping package, undergoes decomposition, combustion, or both when heated to temperatures exceeding 150{degrees}C. Several DT-18 packages that had previously undergone hypothetical thermal accident testing were opened and Celotex {trademark} charring depths ranging from {1/2} to 1 {1/2} in. were recorded. The majority of char depth data taken was between 3/4 and 1 {1/4} in. One-dimensional HEA… more

Chemical Technology Division, Unit Operations Section Monthly Progress Report, August 1961

Description: Engineering studies of a 6-in.-ID countercurrent foam column were started. The capacity of Mark II Stacked Clone Contactor was found to be limited by gradually increasing entrainment. Thoria sols were prepared from trough denitrator products in a conical bottom tank agitated by circulation through an external centrifugal pump. Experimental results agreed favorably with predicted results for the reaction of CO with CuO and fur the simultaneous reactions of H/ sub 2/ and CO with CuO. In a 2-in. d… more

Hydrogen-Transfer and Charge Transfer in Photochemical and High Energy Radiation Induced Reactions: Effects of Thiols. Final Report, February 1, 1960-January 31, 1979

Description: Absorption of ultraviolet or visible light, or high energy radiation, may lead to highly reactive free radicals. Thiols affect the reactions of these radicals in the following ways: (1) transfer of hydrogen from sulfur of the thiol to a substrate radical, converting the radical to a stable molecule, and the thiol to a reactive thiyl radical; and (2) transfer of hydrogen from a substrate radical or molecule to thiyl, regenerating thiol. The thiol is thus used repeatedly and a single molecule may… more

Effect of acidity on microbial processes in a forest soil

Description: The objective of this study is to obtain comprehensive baseline information on the microbial activity in a forest soil in order to begin an evaluation of the impact of pollutants resulting from energy related activities. Since most of the soils on Long Island, New York, are poorly buffered and may respond to acid precipitation more quickly, it was decided to study the effect of acidity on various microbial processes. A Riverhead sandy loam soil collected from an oak-pine forest with a pH of 4.6… more

Immobilization of high-level defense wastes in SYNROC-D: recent research and development results on process scale-up

Description: SYNROC is a titanate-based ceramic waste form being developed to immobilize high-level nuclear reactor wastes. SYNROC-D is a unique variation of SYNROC designed to contain high-level defense wastes, particularly those in storage at the Savannah River Plant (SRP). We review recent research and development on SYNROC-D processing options and report on work in progress on various unit operations. The overall immobilization process can be divided into three general parts: (1) slurry preparation (for… more

Thermal cycling tests on surface-mount assemblies

Description: The capability of surface-mount (SM) solder joints to withstand various thermal cycle stresses was evaluated through electrical circuit resistance changes of a test pattern and by visual examination for cracks in the solder after exposure to thermal cycling. The joints connected different electrical components, primarily leadless-chip carriers (LCCs), and printed wiring-board (PWB) pads on different laminate substrates. Laminate compositions were epoxy-glass and polyimide-glass with and without… more

Office of Technology Development's integrated program for development of in situ remediation technologies

Description: The In-Situ Remediation Integrated Program (ISR IP) was initiated in FY 1991 and is progressing through the planning stages. The ISR IP currently plans to invest in the development of in situ bioremediation for the cleanup of volatile organics in the vadose zone and in groundwater, and in R D activities to support the development of electrokinetics. Additional investment decisions will be made as a result of convening technical support groups to evaluate and recommend R D activities for other i… more

Biomass gasification: yesterday, today, and tomorrow

Description: The solid fuels, biomass and coal, can be converted by gasification into clean gaseous fuels that are easier to distribute and required for many technical processes. The simplest method of conversion is air gasification, producing a low-energy gas well suited for direct-heat or engine applications but unsuitable for pipeline use. Oxygen gasification produces a medium-energy gas composed primarily of CO and H/sub 2/, which can be used industrial pipelines for operation of turbines for power and … more

Electron Transfer Reactions of Excited Dyes With Metal Complexes. Progress Report, March 1, 1978-February 28, 1979. [Iron-Methylene Blue]

Description: An intense absorption band of /sup 3/MBH/sup 2 +/ at 700nm was characterized in several media and its pK/sub A/ was measured to be 7.17 +- .1 in water. Flash photolysis show that semiethylene blue, MBH/sup +/, formed by quenching /sup 3/MBH/sup 2 +/ with Fe/sub II/(H/sub 2/O)/sub 6//sup 2 +/, decays by disproportionation at a diffusion-controlled rate. Rates of decay of the photostationary state of solutions of MB/sup +/ and Fe/sup II/(H/sub 2/O)/sub 6//sup 2 +/ in acidic media were measured us… more

Enzymatic desulfurization of coal

Description: Our experimental approach focuses on the use of enzymes which catalyze the addition of oxygen to organic compounds. In tailoring the application of these enzymes to coal processing, we are particularly interested in ensuring that oxidation occurs at sulfur and not at carbon-carbon bonds. Previous studies with DBT have shown that the reaction most frequently observed in microbial oxidative pathways is one in which DBT is oxidized at ring carbons. These reactions, as we have said, are accompanied… more
