Hydrogen Generation Rate Scoping Study of DOW Corning Antifoam Agent

Description: The antifoam agent DOW Corning Q2-3183A will be added to waste streams in the Hanford River Protection Program-Waste Treatment and Immobilization Plant (RPP-WTP) to prevent foaming. It consists mostly of polydimethylsiloxane (PDMS) and polypropylene glycol (PPG). These and other minor constituents of the antifoam have organic constituents that may participate in radiolytic and chemical reactions that produce hydrogen in Hanford waste. It has been recommended by The WTP R&T Department recommended personnel to treat the organic compounds of the antifoam like the in a similar manner as other organic compounds that are native to the Hanford waste with respect to hydrogen production. This testing has investigated the radiolytic and thermal production of hydrogen from antifoam added to simulant waste solutions to determine if the organic components of the antifoam produce hydrogen in the same manner as the native organic species in Hanford waste. Antifoam additions for this testing were in the range of 4 to 10 wt% to ensure adequate hydrogen detection. Test conditions were selected to bound exposures to the antifoam agent in the WTP. These levels are higher than previously recommended values of 350 mg/L for actual applications in WTP tanks containing air spargers and pulse jet mixers. Limited degradation analyses for the organic components of the antifoam were investigated in this study. A more detailed study involving analyses of antifoam degradation and product formation is in progress at SRNL and results from that study will be reported at a later time. The total organic carbon (TOC) content of the Q2-3183A antifoam was measured to be 39.7 {+-} 4.9 wt% TOC. This measurement was performed in triplicate with on three different dilutions of the pure antifoam liquid using a TOC combustion analyzer instrument with catalytic oxidation, followed by CO{sub 2} quantification using an infrared detector.

Development of an Experimental Database and Theories for Prediction of Thermodynamic Properties of Aqueous Electrolytes and Nonelectrolytes of Geochemical Significance at Supercritical Temperatures and Pressures

Description: The reactions that cause transformations in organic compounds in the Earth’s crust remain mysterious despite decades of research into how fossil fuel resources form. A major reason for this persistent mysteriousness is the failure of many researchers to realize the intimate involvement of water in those transformations. Our goal was to overcome this staggering ignorance by developing the means to calculate the consequences of reactions involving organic compounds and water. We pursued this research from 1989 through 2006, and this report focuses on progress between 2002 and 2006. There were two major obstacles that we overcame in the course of this research. On the one hand, we developed new theoretical equations that allow researchers to make these calculations. On the other hand, we critiqued available data and provided sound means to make estimates in the absence of experimental data for hundreds of organic compounds dissolved in water. Finally, we merged these two lines of research into an interactive web site that allows users to do the calculations with the equations and data. We call the web site ORCHYD for: “ORganic Compounds HYDration properties database,” but it is far more than a database since it allows users to make extremely accurate predictions of data that may never have been measured. Our progress greatly exceeded our anticipations, and has permitted many new research investigations that were previously impossible. Despite the abrupt termination of funding for this project by the Department of Energy, we are maintaining the web site for the international scientific community. Major research results were published in eleven scientific papers, so they are all in the public domain. Benefits to the public include a new, rigorous, quantitative approach to testing ideas about the fate of organic compounds dissolved in water. These tests can be applied to geochemistry or to industrial ...

Description: The Hanford Site is a decommissioned nuclear productions complex located in south eastern Washington and is operated by the Department of Energy (DOE). From 1955 to 1973, carbon tetrachloride (CCl{sub 4}), used in mixtures with other organic compounds, was used to recover plutonium from aqueous streams at Z Plant located on the Hanford Site. The aqueous and organic liquid waste that remained at the end of this process was discharged to soil columns in waste cribs located near Z Plant. Included in this waste slurry along with CCl{sub 4} were tributyl phosphate, dibutyl butyl phosphate, and lard oil. (Truex et al., 2001). In the mid 1980's, CCl{sub 4} was found in the unconfined aquifer below the 200 West Area and subsequent ground water monitoring indicated that the plume was widespread and that the concentrations were increasing. It has been estimated that approximately 750,000 kg (826.7 tons) of CCl{sub 4} was discharged to the soil from 1955 to 1973. (Truex et al., 2001). With initial concentration readings of approximately 30,000 parts per million by volume (ppmv) in one well field alone, soil vapor extraction began in 1992 in an effort to remove the CCl{sub 4} from the soil. (Rohay, 1999). Since 1992, approximately 78,607.6 kg (86.65 tons) of CCl{sub 4} have been extracted from the soil through the process of soil vapor extraction and 9,409.8 kg (10.37 tons) have been removed from the groundwater. (EPA, 2006). The success of this environmental cleanup process benefited not only the environment but also workers who were later involved in the retrieval of solid waste from trenches that were in or near the CCl{sub 4} plume. Solid waste was buried in trenches near Z Plant from 1967 to 1990. The solid waste, some of which was chemically and/or radioactively contaminated, was buried in trenches in ...

Evaluation of the effects of long-term-storage in salt caverns on the physical and chemical properties of certain crude oils and distillate fuel oils. Final report

Description: The effects of long-term storage of crude oil and fuel oil in salt caverns were investigated. Fifty oil and brine samples from three caverns in West Germany were analyzed. Results show that: (a) mixing has taken place but variation in properties such as density and viscosity are negligible; (b) some primary theoretical layers are still recognizable, based on the concentration of sulfur, mercaptans, salt, as well as by neutralization number; and (c) mixing occurs more readily when a heavy crude oil is stored above a light crude. It is concluded that crude and fuel oil have not undergone any deleterious changes. (DC)

Three-phase permeabilities and other characteristics of 260-mD fired Berea

Description: A laboratory investigation was conducted to determine relative permeabilities and other characteristics of a 260-mD fired Berea sandstone. The mineralogical and physical characteristics of the sample were characterized by XRD tests, thin section analyses, mercury injection tests, and centrifuge capillary pressure and wettability tests. Two-phase oil/water relative permeabilities were measured under several stress conditions. Resistivity characteristics of the sample were also evaluated during several of the oil/water tests. Oil/gas and gas/water relative permeabilities were measured during steady-state tests. Three-phase steady-state oil/gas/water tests were performed for six DDI saturation trajectories (decreasing brine and oil saturations, increasing gas saturation) in which the sample was not cleaned between saturation trajectories.

The effects of viscous forces on three-phase relative permeability

Description: The overall objective of Three-Phase Relative Permeability Project (BE9) is to develop guidelines for improving the accuracy of three-phase relative permeability determinations. This report summarizes previous studies and explains the progress made at NIPER on studying the effect of variations in viscous forces on three-phase relative permeabilities by changing the viscosity of both wetting and nonwetting phases. Significant changes were observed due to viscosity variations. An increase in oil viscosity reduced the relative permeability to gas; an increase in brine/(wetting-phase) viscosity reduced the relative permeability to brine. A slight increase in gas relative permeability was also observed. These observations suggest that the viscosities of both oil and water influence three-phase permeability data. During this study, data scatter was sometimes encountered which was comparable to that of published results. The causes of this scatter are outlined in this report and remedial attempts are discussed. 20 refs., 16 figs., 5 tabs.

Chemistry and structure of coal derived asphaltenes and preasphaltenes. Quarterly progress report, October-December 1979

Description: The solvent refined coal liquid from the Pittsburg and Midway Coal Mining Company pilot plant located at Fort Lewis, Washington, has been received and separated reproducibly by the standard solvent fractionation method into three fractions. The coal liquid received is so-called stripper bottom product from SRC-II mode. Table I shows the coal liquefaction reaction conditions and the composition of the products. The 300 cc autoclave system equipped with injection loading, withdrawal systems, and the temperature controller, described before, was used as the reaction vessel. In most reaction studies, tetralin was used as a transport vehicle oil. It was used also for donating hydrogen to the acceptor compounds. Nitrogen gas, instead of hydrogen, has been used for the pressure system, since this simplifies the reaction and gives a clearer picture for the reaction between reactants and solvent. The conversion results on the pentane-soluble (PS) fraction at different conditions are shown in Table III, while the isothermal reaction results on it are in Table IV. With tetralin as a vehicle oil, the results show that only small or negligible amounts of PS are converted into A and BI fractions. However, when PS is pyrolyzed, 26% is polymerized into A and BI fractions. This indicates that tetralin can suppress the formation of A and BI fractions from PS. It is also noted that the composition of coal liquid may change during distillation because of polymerization.

Development of an advanced, continuous mild gasification process for the production of coproducts

Description: Research continued on the production of coproducts from continuous mild gasification. During the third quarter of 1990, work focused on start-up and operation of the 50 pound/hour char-to-carbon (CTC) process research unit (PRU). Start-up procedures have been finalized for the methane production reactor, and the design temperature has been achieved. Flows and pressures for the overall process have been balanced and optimized. We have achieved temperatures above 1500{degree}F in the carbon formation reactor. Upgrading experiments on mild gasification pitch have also continued on a pitch produced in run MG-122. Results of heat treating and catalytic treating tests are reported.

Short and long-term tests of elastomers with hot hostile fluids. Environmental Compatibility Test Program final report

Description: Equipment manufacturers and elastomer houses were called to find the best currently available high-temperature elastomers. Tensile specimens of 46 such compounds were immersion tested for five days in six 190C fluids of interest: isobutane, brine, ASTM No. 1 oil, ASTM No. 3 oil, Pacer DHT-185M synthetic oil, and Chevron Cylinder Grade 460X oil. The best eight were selected based upon the least change in mechanical properties. These eight were then simultaneously tested (a) by immersion in five 190C fluids for six months and (b) as 0-rings for 46 hours at 190C, 230C, and 265C (accelerated ageing) in three fluids and at a differential pressure of 21 MPa. Based upon these 0-ring tests, four compounds were selected for testing as 0-rings in three 204C fluids at 21 MPa differential pressure. The data were evaluated and conclusions were drawn. Conclusions and recommendations are provided. There was immersion testing of primarily L'Garde compounds in brine and CL3 mineral oil for 6 months at 190C. L'Garde had formulated several compounds specifically for 260C brine, and their applicability to a specific problem was assessed early in the program.

Aging test results of an asphalt membrane liner

Description: The objective of the asphalt aging study described in this report was to determine the expected performance lifetime of a catalytically airblown asphalt membrane as a seepage barrier for inactive uranium mill tailings. The study, conducted by Pacific Northwest Laboratory for the Department of Energy's Uranium Mill Tailings Remedial Action Program, showed through chemical compatibility tests that the asphalt membrane is well suited for this purpose. The chemical compatibility tests were designed to accelerate the aging reactions in the asphalt and to determine the accelerated aging effect. Higher temperatures and oxygen concentrations proved to be effective acceleration parameters. By infrared spectral analysis, the asphalt was determined to have undergone 7 years of equivalent aging in a 3-month period when exposed to 40/sup 0/C and 1.7 atm oxygen pressure. However, the extent of aging was limited to a maximum penetration of 0.5% of the total liner thickness. It was concluded that the liner could be expected to be effective as a seepage barrier for at least 1000 years before the entire thickness of the liner would be degraded.

Selection of fluids for tritium pumping systems

Description: The degradation characteristics of three types of vacuum pump fluids, polyphenyl ethers, perfluoropolyethers and hydrocarbon oils were reviewed. Fluid selection proved to be a critical factor in the long-term performance of tritium pumping systems and subsequent tritium recovery operations. Thermal degradation and tritium radiolysis of pump fluids produce contaminants which can damage equipment and interfere with tritium recovery operations. General characteristics of these fluids are as follows: polyphenyl ether has outstanding radiation resistance, is very stable under normal diffusion pump conditions, but breaks down in the presence of oxygen at anticipated operating temperatures. Perfluoropolyether fluids are very stable and do not react chemically with most gases. Thermal and mechanical degradation products are inert, but the radiolysis products are very corrosive. Most of the degradation products of hydrogen oils are volatile and the principal radiolysis product is methane. Our studies show that polyphenyl ethers and hydrocarbon oils are the preferred fluids for use in tritium pumping systems. No corrosive materials are formed and most of the degradation products can be removed with suitable filter systems.

Megavolt pulse transformer powered by a fast plate generator

Description: A compact air-core transformer is described that has been used to produce megavolt pulses across resistive impedances > 20 ..cap omega.. when powered by fast explosive plate generators. The step-up transformer features many of the techniques employed in the tape-wound transformers of Martin and Smith. The primary winding of the transformer is a discrete, single-turn coil. The multi-turn secondary coil is fabricted separately, encapsulated in a thin-walled container, and vacuum impregnated with dielectric grading fluid. Once assembled, the transformer is immersed in oil. This transformer has a 0.8 coupling coefficient. Transformers of this type are especially attractive for single-shot applications because of their simplicity and ease of construction.

Obligate autotrophy in the ammonia oxidizing bacterium Nitrosomonas europaea.

Description: Closing report for project DOE-FG02-03ER15436. The project studied obligate autotrophy in the ammonia oxidizing bacterium Nitrosomonas europaea. Nitrosomonas europaea can obtain all of its energy and reductant for growth from the oxidation of ammonia to nitrite and is, therefore, classified as a chemolithotroph. This bacterium is also an autotroph, which can derive all cellular carbon from carbon dioxide. N. europaea seems incapable of growth with other carbon or energy sources. This restricted capability is surprising given that ammonia is a poor energy source. The main goal of the project was to examine the basis of autotrophy in N. europaea or, thought of another way, to determine the barriers to heterotrophy. The approach was enabled by the N. europaea genome sequence, stimulating new ways of thinking about this physiological paradox—an insistence on a single, albeit poor, energy source. Objective 1 was to examine the expression and regulation of the genes coding for alpha-ketoglutarate dehydrogenase, determine if the enzyme’s activity is present, and determine whether alteration of the expression levels influences autotrophic growth. Although Nitrosomonas europaea lacks measurable alpha-ketoglutarate dehydrogenase activity, the genome sequence revealed the presence of the genes encoding the enzyme. A knockout mutation was created in the sucA gene encoding the E1 subunit. Compared to wild-type cells, the mutant strain showed an accelerated loss of ammonia monooxygenase and hydroxylamine oxidoreductase activities upon entering stationary phase. In addition, unlike wild-type cells, the mutant strain showed a marked lag in the ability to resume growth in response to pH adjustments in late stationary phase. The results were published in Hommes N.G., Kurth E. G., Sayavedra-Soto L.A., and Arp D.J. (2006) Disruption of sucA, which encodes a subunit of alpha-ketoglutarate dehydrogenase, affects the survival of Nitrosomonas europaea in stationary phase. Journal of Bacteriology 188:343-347.

Development of an advanced continuous mild gasification process for the production of coproducts: Task 4. 6, Technical and economic evaluation

Description: Morgantown Energy Technology Center (METC) of DOE has sponsored, and continues to sponsor, programs for the development of technology and market strategies which will lead to the commercialization of processes for the production of coproducts from mild gasification of coal. It has been recognized by DOE and industry that mild gasification is a promising technology with potential to economically convert coal into marketable products, thereby increasing domestic coal utilization. In this process, coal is devolatilized under non- oxidizing conditions at mild temperature (900--1100{degrees}F) and pressure (1--15psig). Condensation of the vapor will yield a liquid product that can be upgraded to a petroleum substitute, and the remaining gas can provide the fuel for the process. The residual char can be burned in a power plant. Thus, in a long-term national scenario, implementation of this process will result in significant decrease of imported oil and increase in coal utilization.

Emulsified industrial oils recycling

Description: The industrial lubricant market has been analyzed with emphasis on current and/or developing recycling and re-refining technologies. This task has been performed for the United States and other industrialized countries, specifically France, West Germany, Italy and Japan. Attention has been focused at emulsion-type fluids regardless of the industrial application involved. It was found that emulsion-type fluids in the United States represent a much higher percentage of the total fluids used than in other industrialized countries. While recycling is an active matter explored by the industry, re-refining is rather a result of other issues than the mere fact that oil can be regenerated from a used industrial emulsion. To extend the longevity of an emulsion is a logical step to keep expenses down by using the emulsion as long as possible. There is, however, another important factor influencing this issue: regulations governing the disposal of such fluids. The ecological question, the respect for nature and the natural balances, is often seen now as everybody's task. Regulations forbid dumping used emulsions in the environment without prior treatment of the water phase and separation of the oil phase. This is a costly procedure, so recycling is attractive since it postpones the problem. It is questionable whether re-refining of these emulsions - as a business - could stand on its own if these emulsions did not have to be taken apart for disposal purposes. Once the emulsion is separated into a water and an oil phase, however, re-refining of the oil does become economical.

Low severity upgrading of F-T waxes with solid superacids

Description: We have discovered that the isomerization and hydrocracking of a long chain paraffin, n-hexadecane, with a solid superacid such as ZrO{sub 2}/SO{sub 4} gives very high selectivities, (i.e., > 90% to hydrocracked isoparaffins, C{sub 4}-C{sub 13}) in the presence of platinum and a low pressure of hydrogen. Undesirable light gases (methane and ethane) are not produced during these reactions. In addition, a high multi-branched to monobranched ratio of long chain hydrocarbons is produced. We have written the formula for this catalyst as Pt/ZrO{sub 2}/SO{sub 4}. Early attempts during this first quarter to reproduce this catalyst for the hydrocracking and isomerization of n-hexadecane gave results which were not reproducible, conversion varying from a few percent to 70%. It was, therefore, of utmost importance to devise a procedure that could be depended upon to synthesize a reproducible catalyst would give high conversions and high selectivities to cracked and isomerized products of high fuel and lubricating oil values. The catalysts should be active under mild conditions, i.e., below 170{degrees}C and hydrogen pressures below 350 psi. Conventional heavy end cracking catalysts (modified zeolites) are active at 300--400{degrees}C.

An analysis of heating fuel market behavior, 1989--1990

Description: The purpose of this report is to fully assess the heating fuel crisis from a broader and longer-term perspective. Using EIA final, monthly data, in conjunction with credible information from non-government sources, the pricing phenomena exhibited by heating fuels in late December 1989 and early January 1990 are described and evaluated in more detail and more accurately than in the interim report. Additionally, data through February 1990 (and, in some cases, preliminary figures for March) make it possible to assess the market impact of movements in prices and supplies over the heating season as a whole. Finally, the longer time frame and the availability of quarterly reports filed with the Securities and Exchange Commission make it possible to weigh the impact of revenue gains in December and January on overall profits over the two winter quarters. Some of the major, related issues raised during the House and Senate hearings in January concerned the structure of heating fuel markets and the degree to which changes in this structure over the last decade may have influenced the behavior and financial performance of market participants. Have these markets become more concentrated Was collusion or market manipulation behind December's rising prices Did these, or other, factors permit suppliers to realize excessive profits What additional costs were incurred by consumers as a result of such forces These questions, and others, are addressed in the course of this report.

Bench-scale co-processing

Description: The objective of this contract is to extend and optimize UOP's single-stage, slurry-catalyzed co-processing scheme. The current task is to complete a long-term operability run using a 0.05 wt-% Mo-based catalyst at approximately 460{degrees}C. The objectives of this run are to demonstrate that high-severity conditions can be run for an extended period of time (at least one month) and to collect enough product sample to do a complete Hempel fractionation and detailed characterization of the individual naphtha, distillate, and VGO cuts. This information will be used to reevaluate the engineering design and product upgrading scheme that was developed under the first co-processing contract (DE-AC22-84PC70002). During the current two quarters, the long-term operability study was unsuccessfully attempted several times. This report discusses these attempts.

Development and application of a permit information system for shale oil (PERMISSO). Final report appendix: summary sheets of regulations required for oil shale development, June 1978--May 1979

Description: This appendix is comprised of summaries of various governmental permits, licenses and other approvals required for oil shale development. The summaries were completed during the period June--October 1978, and are current as of July 1, 1978, although more recent authority was cited in some cases. One of the major purposes of Phase II of the project will be to update these summaries as statutes and regulations are added, changed or eliminated. This updating will be particularly important in the case of environmental permits and approvals. Many legislative and regulatory changes affecting environmental requirements are pending at this time and will alter many of the summaries herein. In addition, many regulatory proposals have been or likely will be challenged in the courts. When such conflicts are resolved further changes may be in order.

Analysis of organic sulfur and nitrogen in coal via tandem degradation methods

Description: With the recent increase in concern for environmental issues and the implication of sulfur and nitrogen in coal combustion products as prime causes of acid rain, it has become clear that there is an urgent need for alternative methods for determining the nature of organic sulfur and nitrogen compounds in coal. The present study couples mold oxidative and reductive procedures to enhance the depolymerization of coal and its constituent macerals and the quantities of produces amenable to analysis. The study also seeks to apply the degradative techniques to coal asphaltenes, since they are believed to be polymeric structures similar to the whole coal, but smaller and more readily analyzed. While the research effort will focus on Illinois coal, additional samples with even higher sulfur contents will also used, allowing for much easier detection and characterization of organic sulfur structures. A preliminary tests of this hypothesis indicates that many of the same sulfur compounds are present in both the Illinois and in an extremely sulfur-rich coal and that the more complex sulfur compounds are indeed more concentrated in the sulfur-rich sample.
