Acoustic Monitor for Liquid-Solid Slurries Measurements at Low Weight Fractions

The principal objective of the project is to develop an acoustic probe for determining the weight fraction of particles in a flowing suspension. The suspension can be solid-liquid (S-L) or solid-gas-liquid (S-G-L). The work will include testing the theory of acoustic wave propagation in suspensions and demonstrating the application of the probe by installing it on a flow loop through which a suspension is flowing and determining the particle weight fraction. The signal from the probe must be processed such that the noise arising from the presence of gas bubbles is removed to yield an accurate estimate of the particle weight fraction. Particular attention will be given to testing suspensions with low particle weight fractions since slurries to be transported in nuclear waste processing will have low particle weight fractions. Originally, the probe was to be developed and tested at Syracuse University (SU) then installed and tested at Oak Ridge National Laboratories (ORNL) for surrogate slurries from the Hanford Nuclear site. However, after discussions between SU and ORNL in June 2002 it was agreed that all tests would be conducted at SU.

Active flow control for maximizing performance of spark ignited stratified charge engines. Final report

Reducing the cycle-to-cycle variability present in stratified-charge engines is an important step in the process of increasing their efficiency. As a result of this cycle-to-cycle variability, fuel injection systems are calibrated to inject more fuel than necessary, in an attempt to ensure that the engines fire on every cycle. When the cycle-to-cycle variability is lowered, the variation of work per cycle is reduced and the lean operating limit decreases, resulting in increased fuel economy. In this study an active flow control device is used to excite the intake flow of an engine at various frequencies. The goal of this excitation is to control the way in which vortices shed off of the intake valve, thus lowering the cycle-to-cycle variability in the flow field. This method of controlling flow is investigated through the use of three engines. The results of this study show that the active flow control device did help to lower the cycle-to-cycle variability of the in-cylinder flow field; however, the reduction did not translate directly into improved engine performance.

Advanced Catalytic Hydrogenation Retrofit Reactor

Industrial hydrogenation is often performed using a slurry catalyst in large stirred-tank reactors. These systems are inherently problematic in a number of areas, including industrial hygiene, process safety, environmental contamination, waste production, process operability and productivity. This program proposed the development of a practical replacement for the slurry catalysts using a novel fixed-bed monolith catalyst reactor, which could be retrofitted onto an existing stirred-tank reactor and would mitigate many of the minitations and problems associated with slurry catalysts. The full retrofit monolith system, consisting of a recirculation pump, gas/liquid ejector and monolith catalyst, is described as a monolith loop reactor or MLR. The MLR technology can reduce waste and increase raw material efficiency, which reduces the overall energy required to produce specialty and fine chemicals.

Advanced Modeling and Materials in Kraft Pulp Mills

This CRADA provided technical support to the Weyerhaeuser Company on a number of issues related to the performance and/or selection of materials at a number of locations in a pulp and paper mill. The studies related primarily to components for black liquor recovery boilers, but some effort was directed toward black liquor gasifiers and rolls for paper machines. The purpose of this CRADA was to assist Weyerhaeuser in the evaluation of materials exposed in various paper mill environments and to provide direction in the selection of alternate materials, when appropriate.

Advances in Low-Defect Multilayers for EUVL Mask Blanks

Low-defect multilayer coatings are required to fabricate mask blanks for Extreme Ultraviolet Lithography (EUVL). The mask blanks consist of high reflectance E W multilayers on low thermal expansion substrates. A defect density of 0.0025 printable defects/cm{sup 2} for both the mask substrate and the multilayer is required to provide a mask blank yield of 60%. Current low defect multilayer coating technology allows repeated coating-added defect levels of 0.05/cm{sup 2} for defects greater than 90 nm polystyrene latex sphere (PSL) equivalent size for lots of 20 substrates. Extended clean operation of the coating system at levels below 0.08/cm{sup 2} for 3 months of operation has also been achieved. Two substrates with zero added defects in the quality area have been fabricated, providing an existence proof that ultra low defect coatings are possible. Increasing the ion source-to-target distance from 410 to 560 mm to reduce undesired coating of the ion source caused the defect density to increase to 0.2/cm{sup 2}. Deposition and etching diagnostic witness substrates and deposition pinhole cameras showed a much higher level of ion beam spillover (ions missing the sputter target) than expected. Future work will quantify beam spillover, and test designs to reduce spillover, if it is confirmed …

Advancing Technology and Methodology to Streamline Environmental Compliance

By early 2000, fifteen oil and gas State Agencies were using RBDMS or a RBDMS utility to handle a significant amount or all of their data management needs. There are three additional State slated to begin implementation this year. There are an additional twelve State agencies that are not utilizing this technology that have proven to be very useful for so many other States. This project will allow for the base RBDMS install in all State oil and gas agency that desire it.

Air Force Aircraft: Preliminary Information on Air Force Tanker Leasing

Correspondence issued by the General Accounting Office with an abstract that begins "GAO addressed the Air Force's plan to replace a portion of its KC-135 aerial refueling tanker fleet with leased Boeing 767 aircraft. Although the Air Force has a long term requirement to replace its aging fleet of KC-135 tankers, the urgency of the need in the short term is unclear. The Air Force stated that the leasing arrangement would allow it to acquire new tankers three years earlier than through its most recent procurement plan. This would allow the Air Force to retire old, less capable KC-135s, thus saving maintenance costs on those aircraft. Because the Air Force is still negotiating the lease details, it could not provide information on the cost effectiveness of leasing aircraft instead of purchasing them. Although GAO has not taken a position on the overall policy of leasing versus purchasing defense equipment, it found that, from a cost standpoint, leasing is more expensive in the long run. Because the 767 aircraft is larger than the KC-135, there will be some infrastructure improvement costs, such as for building or modifying hangars, taxiways, and runway aprons. Additional costs would likely include simulators and project management. …

Airport Finance: Using Airport Grant Funds for Security Projects Has Affected Some Development Projects

A letter report issued by the General Accounting Office with an abstract that begins "The events of September 11, 2001 created several new challenges for the aviation industry in ensuring the safety and security of the national airport system. Chief among them is deciding to what extent Airport Improvement Program (AIP) grant funds should be used to finance the new security requirements at the nation's airports. Although many in the aviation industry believe that funding security projects has become even more important in the aftermath of September 11, they also recognize the need to continue funding other airport development projects, such as those designed to enhance capacity in the national airport system. During fiscal year 2002, the Federal Aviation Association (FAA) awarded a total of $561 million, 17 percent of the $3.3 billion available for grants, in AIP grant funds to airports for security projects related to the events of September 11, 2001. This amount is the largest amount awarded to airports for security projects in a single year since the program began in 1982. Based on data provided by FAA, all of the security projects funded with AIP grants since the events of September 11, 2001, met the legislative …

AISI/DOE Technology Roadmap Program: A Technology of Low Coal Rate and High Productivity of RHF Ironmaking

An economical and environment-friendly ironmaking process based on heating the chemiexecy self-sufficient green balls of iron ore and coal in a hearth furnace is being developed with financial support from AISI members and DOE. DRI, which is hot (1400 C), dense (3.2 g/cm) and of high degree of metallization (95%), has been produced in laboratory and in a pilot plant in Genoa, Italy. Products of such quality have been made from American and Brazilian ores, BOF sludge, EAF dust/BOF sludge mixtures and millscale. The removal of zinc and lead from green balls by this process is essentially complete. In comparison with typical blast furnace operation, the new technology with a melter would have a lower total coal rate by 200kg.THM. The elimination of cokemaking and high temperature agglomeration steps, and a simpler gas handling system would lead to lower capital and operating costs. In comparison with commercial RHF practice it is different in atmosphere (fully oxidized at 1600 to 1650 C), in bed height (120 mm instead of 20-25 mm) and in pellet composition (much less coal but of higher VM). The combined effect leads to three times higher furnace productivity, lower coal consumption and superior DRI quality. The risk …

ALARA Analysis of Radiological Control Criteria Associated with Alternatives for Disposal of Hazardous Wastes

This ALARA analysis of Radiological Control Criteria (RCC) considers alternatives to continued storage of certain DOE mixed wastes. It also considers the option of treating hazardous wastes generated by DOE facilities, which have a very low concentration of radionuclide contaminants, as purely hazardous waste. Alternative allowable contaminant levels examined correspond to doses to an individual ranging from 0.01 mrem/yr to 10 to 20 mrem/yr. Generic waste inventory data and radionuclide source terms are used in the assessment. Economic issues, potential health and safety issues, and qualitative factors relating to the use of RCCs are considered.
