Plutonium scrap recovery at Savannah River: Past, present, and vision of the future

Description: As a result of the changing requirement, plus environmental and regulatory commitments, SRP now has essentially completed its paradigm shift. SRP has been transformed from primarily a reprocessor of irradiated uranium targets to primarily a reprocessor of non-specification plutonium. This is the mission which will carry SRP into the 21st Century. Accomplishment of the defined goals for the three-pronged RandD program will achieve several objectives: exploit new processes for recovering low-grad… more

Hot gas desulfurization with oxides of zinc, iron, and vanadium

Description: The objective of this study is to develop an improved sorbent which can reduce H{sub 2}S levels up to 1 ppmv or less, which can stabilize zinc, and produce economically recoverable amounts of elemental sulfur during regeneration. For this purpose, the desulfurization performance of sorbents prepared by the addition of various amounts of V{sub 2}O{sub 5} to the zinc ferrite sorbent is investigated.

Recovery of platinum from concentrated sodium chloride brine by electrodeposition on vitreous carbon

Description: The voltammetric characteristics of Pt(II) and Pt(IV) have been examined at a vitreous carbon electrode in slightly acidic 3M (approx. 15 wt %) NaCl solutions. Pt(IV) is reduced to Pt(II) at approx. 0 V and Pt(II) is reduced to Pt(0) at approx. -0.5 V vs Ag-AgCl. The rate of deposition of platinum metal at -0.5 V is very low on bare carbon, but increases as the coverage of platinum increases. The potential at which hydrogen is evolved in this medium is approx. -0.85 V. A technique has been test… more

Economics of microwave plasma dissociation of H sub 2 S

Description: The conventional treatment technology for hydrogen-sulfide is based on Claus chemistry; elemental sulfur is recovered but the hydrogen is lost as water although the fuel value of the hydrogen is recovered as heat. A new waste treatment technology, reported in the Soviet literature, has been validated in an experimental program at Argonne National Laboratory. The new technology uses microwave energy to dissociate hydrogen-sulfide and recovers both elemental sulfur and hydrogen. Recovery of the h… more

Ferrocyanide-containing waste tanks: Ferrocyanide chemistry and reactivity

Description: The complexing constant for hexacyano-iron complexes, both Fe(2) and Fe(3), are exceptionally large. The derived transition metal salts or double salts containing alkali metal ions are only slightly soluble. The various nickel compounds examined in this study, i.e., those predicted to have been formed in the Hanford waste scavenging program, are typical examples. In spite of their relative stability towards most reagents under ambient conditions, they are all thermodynamically unstable towards … more

Recovery and reuse of asphalt roofing waste. Final report

Description: Burning of asphalt roofing waste as a fuel and incorporating asphalt roofing waste in bituminous paving were identified as the two outstanding resource recovery concepts out of ten studied. Four additional concepts might be worth considering under different market or technical circumstances. Another four concepts were rated as worth no further consideration at this time. This study of the recovery of the resource represented in asphalt roofing waste has identified the sources and quantities of … more

Maximizing the life cycle of plastics. Final report

Description: The Plastics Research Institute has conducted a coordinated research program designed to extend the useful life of plastics. Since feedstock for practically all synthetic plastics is derived from fossil fuel, every effort should be made to obtain the maximum useful life from these materials. Eventually, plastic scrap may be used as a fuel supplement, but this disposal route should be followed only after the scrap is no longer reusable in its polymeric form. The extent to which plastic scrap wil… more

Industrial recovered-materials-utilization targets for the textile-mill-products industry

Description: The Congress, in the National Energy Conservation and Policy Act of 1978 (NECPA), directed the Department of Energy to establish materials recovery targets for the metals and metal products, paper and allied products, rubber, and textile-mill-products industries. The targets were developed to provide incentives for using energy-saving recorded materials and to provied a yardstick for measuring progress and improvement in this endeavor. The NECPA indicates that the targets should represent the m… more

Literature search for the non-aqueous separation of zinc from fuel rod cladding. [After dissolution in liquid metal]

Description: This report reviews the literature of processes for the nonaqueous separation of zinc from dissolved fuel assembly cladding. The processes considered were distillation, pyrochemical processing, and electrorefining. The last two techniques were only qualitatively surveyed while the first, distillation, was surveyed in detail. A survey of available literature from 1908 through 1978 on the distillation of zinc was performed. The literature search indicated that a zinc recovery rate in excess of 95… more

Reclaiming sulfur hexafluoride: a system to repurify, store, and recirculate SF/sub 6/

Description: Large quantities of sulfur hexafluoride (SF/sub 6/) gas are used in the operation of electron beam accelerators in Sandia Laboratories Technical Area V. A commercial SF/sub 6/ gas transfer cart has been modified to reclaim this gas by repurification and storage for later use. The system will not be installed and in operation until about March 1978, but it is anticipated it will be much more economical than current and estimated future costs for purchasing replacement SF/sub 6/.

Development of a risk analysis model. Appendix E. 1,000 ton per day anaerobic digestion plant case study, Final report, October 1979

Description: The Department of Energy (DOE) is investigating processes for the recovery of energy from urban wastes, with the intention of determining how the barriers standing in the way of commercialization of these processes can be overcome. Commercialization of any urban waste energy recovery process is constrained by many complex, uncertain components and interactions. Technical, economic, and institutional barriers presently exist which increase both the real and perceived risks of making such a ventu… more

In-plant testing of microbubble column flotation

Description: Microbubble column flotation (MCF) was developed at the Virginia Center for Coal and Minerals Processing (VCCMP) for the selective recovery of fine particles. Bench-scale test work conducted at VCCMP, largely under the sponsorship of the U.S. Department of Energy (DOE), showed that the technology worked well for both coal and mineral applications. For the technology to be commercially successful, however, a full-scale demonstration of the MCF technology was deemed necessary. This report summari… more

Hydrotreating the bitumen-derived hydrocarbon liquid produced in a fluidized-bed pyrolysis reactor

Description: The pyrolysis of bitumen-impregnated sandstone produces three primary product streams: C{sub 1}-C{sub 4} hydrocarbons gases, a C{sub 5}{sup +} total liquid product, and a carbonaceous residue on the spent sand. The bitumen-derived hydrocarbon liquid was significantly upgraded relative to the native bitumen: it had a higher API gravity, lower Conradson carbon residue, asphaltene content, pour point and viscosity and a reduced distillation endpoint relative to the native bitumen. The elemental co… more
