Advanced Flue Gas Desulfurization (AFGD) demonstration project: Volume 2, Project performance and economics. Final technical report
The project objective is to demonstrate removal of 90--95% or more of the SO{sub 2} at approximately one-half the cost of conventional scrubbing technology; and to demonstrate significant reduction of space requirements. In this project, Pure Air has built a single SO{sub 2} absorber for a 528-MWe power plant. The absorber performs three functions in a single vessel: prequencher, absorber, and oxidation of sludge to gypsum. Additionally, the absorber is of a co- current design, in which the flue gas and scrubbing slurry move in the same direction and at a relatively high velocity compared to conventional scrubbers. These features all combine to yield a state- of-the-art SO{sub 2} absorber that is more compact and less expensive than conventional scrubbers. The project incorporated a number of technical features including the injection of pulverized limestone directly into the absorber, a device called an air rotary sparger located within the base of the absorber, and a novel wastewater evaporation system. The air rotary sparger combines the functions of agitation and air distribution into one piece of equipment to facilitate the oxidation of calcium sulfite to gypsum. Additionally, wastewater treatment is being demonstrated to minimize water disposal problems inherent in many high-chloride coals. …

Advanced Thermometrics for Fossil Power Plant Process Improvement
Improved temperature measurements in fossil power plants can reduce heat rate and uncertainties in power production efficiencies, extend the life of plant components, reduce maintenance costs, and lessen emissions. Conventional instruments for measurement of combustion temperatures, steam temperatures, and structural component temperatures can be improved by better specification, in situ calibration, signal processing, and performance monitoring. Innovative instruments can enhance, augment, or replace conventional instruments. Several critical temperatures can be accessed using new methods that were impossible with conventional instruments. Such instruments include high temperature resistance temperature detectors (RTDs), thermometric phosphors, inductive thermometry, and ultrasonic thermometry.

Agricultural Marketing and Regulatory Provisions of the 1996 Farm Bill
The Federal Agricultural Improvement and Reform Act of 1996 (P.L. 104-127), signed into law on April 4, for the first time grants the U.S. Department of Agriculture (USDA) broad-based authority to establish national generic promotion ("check-off") programs for virtually any agricultural commodity. Formerly, individual programs first had to be authorized expressly by Congress. The new law also explicitly authorizes the establishment of new check-off programs for rapeseed and canola, kiwifruit, and popcorn. Other provisions require USDA to establish a new meat and poultry inspection advisory committee; deal with the collection of user fees for the inspection of agricultural imports; and authorize new guidelines to protect horses being transported to slaughter facilities, among other things.

Application of advanced reservoir characterization, simulation, and production optimization strategies to maximize recovery in slope and basin clastic reservoirs, West Texas (Delaware Basin). Technical progress report
The objective of this project is to demonstrate that detailed reservoir characterization of slope and basin clastic reservoirs in sandstones of the Delaware Mountain Group in the Delaware Basin of West Texas and New Mexico is a cost effective way to recover a higher percentage of the original oil in place through strategic placement of infill wells and geologically based field development. Project objectives are divided into two major phases. The objectives of the reservoir characterization phase of the project are to provide a detailed understanding of the architecture and heterogeneity of two fields, the Ford Geraldine unit and Ford West field, which produce from the Bell Canyon and Cherry Canyon Formations, respectively, of the Delaware Mountain Group and to compare Bell Canyon and Cherry Canyon reservoirs. Reservoir characterization will utilize 3-D seismic data, high-resolution sequence stratigraphy, subsurface field studies, outcrop characterization, and other techniques. One the reservoir-characterization study of both field is completed, a pilot area of approximately 1 mi{sup 2} in one of the fields will be chosen for reservoir simulation. The objectives of the implementation phase of the project are to: (1) apply the knowledge gained from reservoir characterization and simulation studies to increase recovery from the …

A data analysis routine to protect confidential information during GC-MS analysis
The Chemical Weapons Convention allows for the collection and analysis of samples at inspection sites, including demilitarization facilities, to verify compliance with treaty obligations. The Preparatory Commission to the OPCW, through its Expert Group on Inspection Procedures, PC-VIII/B/WP.2, has determined that the Technical Secretariat must have analytical equipment that among other things, allows {open_quotes}identification and recording of the detection of chemicals relevant to the purpose of the inspection, but the suppression of the indication and recording of the detection of chemicals and other information unrelated to the purpose of the inspection.{close_quotes} This paper describes unfinished work at the Lawrence Livermore National Laboratory (LLNL) to satisfy this requirement for GC-MS instrumentation.

Determination of the Forms of Nitrogen Released in Coal Tar During Rapid Devolatilization. Semi-Annual Report, November 1, 1995--April 30, 1996
Control of emissions of nitrogen oxides (NO{sub x}) from coal combustion systems is becoming a major design and retrofit consideration. Most NO{sub x} in coal combustion systems comes from nitrogen in the fuel, rather than from nitrogen in the air. Practical emission control strategies include burner design strategies (e.g., low NO{sub x} burners), overfire air, reburning, selective non-catalytic reduction (SNCR) using reduction agents such as NH{sub 3} or urea, and selective catalytic reduction (SCR). The order listed also reflects the order of increasing costs for implementation. It is therefore most economically desirable to perform burner modifications to reduce NO{sub x} emissions rather than other control measures. Low-NO{sub x} burners work on the principle that devolatilized nitrogen species will form N{sub 2} rather than NO{sub x} under locally fuel-rich conditions with sufficient residence time at appropriate temperatures. The amount and form of nitrogen released during devolatilization influence the degree of NO{sub x} reduction attainable using burner design strategies for a given coal. Nitrogen in the char following devolatilization is released by heterogeneous oxidation, and may not be controlled by aerodynamic burner modifications. The objectives of this work are to perform detailed chemical measurements of the nitrogen in coal, tar, and char.

Engineering development of advanced physical fine coal cleaning for premium fuel applications. Quarterly technical progress report 14, January--March 1996
The primary goal of this project is the engineering development of two advanced physical fine coal cleaning processes, column flotation and selective agglomeration, for premium fuel applications. The project scope includes laboratory research and bench-scale testing on six coals to optimize these processes, followed by the design, construction, and operation of a 2-t/hr process development unit (PDU). The project began in October, 1992, and is scheduled for completion by June 1997. During Quarter 14 (January--March 1996), parametric testing of the 30-inch Microcel{trademark} flotation column at the Lady Dunn Plant continued under Subtask 3.2. Subtask 3. 3 testing, investigating a novel Hydrophobic Dewatering process (HD), continued this quarter with parametric testing of the batch dewatering unit. Coal product moistures of 3 to 12 percent were achieved, with higher percent solids slurry feeds resulting in lower product moistures. For a given percent solids feed, the product moisture decreased with increasing butane to dry coal ratios. Stirring time, stirring rate, and settling time were all found to have little effect on the final moisture content. Continuing Subtask 6.4 work, investigating coal-water-fuel slurry formulation for coals cleaned by selective agglomeration, indicated that pH adjustment to 10 resulted in marginally better (lower viscosity) slurries for …

Engineering study of the potential uses of salts from selective crystallization of Hanford tank wastes
The Clean Salt Process (CSP) is the fractional crystallization of nitrate salts from tank waste stored on the Hanford Site. This study reviews disposition options for a CSP product made from Hanford Site tank waste. These options range from public release to onsite low-level waste disposal to no action. Process, production, safety, environment, cost, schedule, and the amount of CSP material which may be used are factors considered in each option. The preferred alternative is offsite release of clean salt. Savings all be generated by excluding the material from low-level waste stabilization. Income would be received from sales of salt products. Savings and income from this alternative amount to $1,027 million, excluding the cost of CSP operations. Unless public sale of CSP products is approved, the material should be calcined. The carbonate form of the CSP could then be used as ballast in tank closure and stabilization efforts. Not including the cost of CSP operations, savings of $632 million would be realized. These savings would result from excluding the material from low-level waste stabilization and reducing purchases of chemicals for caustic recycle and stabilization and closure. Dose considerations for either alternative are favorable. No other cost-effective alternatives that were considered …

Final Report: Theoretical Studies on Radiation-Induced Transformations in Nucleic Acid Bases, May 1, 1993 - April 30, 1996
In the proposal we identified several elemental molecular properties related to the effects observed in genetic material exposed to ionizing irradiation, and we studied them by means of the ab-initio quantum chemistry. The chemistry of irradiation is complex and biological consequences are significant. This includes cell death, mutations, carcinogenic transformations, etc. In the proposal we theoretically modeled several elemental processes related to the radiolysis of components of the nucleic acids, i.e., the pyrimidine nucleobases cytosine, uracine and thymine. Based on the state-of-the-art ab-initio calculations, we obtained information on the structural and spectroscopic properties of transition intermediate reactants.

Fingerprinting of ground water by ICP-MS. Final report
Geochemical investigations of groundwater sources and mixing have relied heavily on the major solutes (Na{sup +}, K{sup +}, Ca{sup 2+}, Mg{sup 2+}, Cl{sup -}, SO{sub 4}{sup 2-}, HCO{sub 3}{sup -}, CO{sub 3}{sup 2-}, {plus_minus}F{sup -}, Br{sup -} , PO{sub 4}{sup 3-}), stable isotopes of hydrogen and oxygen ({delta}D and {delta}{sup 18}O), and, occasionally, radionuclides such as tritium ({sup 3}H) and carbon-14 ({sup 14}C). Problems with geochemical interpretations of such analyses arise from the low number of major solutes (typically between 7 and 8 are reported) which results in insufficient information for definitive interpretations. Moreover, isotopic analyses can be very costly. We present an alternative approach using numerous trace elements that occur naturally in all ground waters and that can now be measured rapidly and routinely using the inductively coupled plasma-mass spectrometer (ICP-MS) at the Harry Reid Center for Environmental Studies (HRC) at a fraction of the cost of isotopic analysis. The tremendous number of solutes that can be measured by ICP-MS necessitates the examination of each data set by multivariate statistical techniques that help to reduce the data and illuminate correlations between trace elements and, therefore, ground waters of similar and/or different origins.
