Development of an advanced, continuous mild gasification process for the production of co-products  

Science Conference Proceedings (OSTI)

Research continued on the production of co-products from mild gasification. This quarter, 10 mild gasification tests were conducted in the 8-inch-I.D. process research unit (PRU). Modifications to the PRU were made during this period to improve mixing and to overcome the caking tendency of the Illinois No. 6 coal. Six of the tests resulted in satisfactory operation at steady conditions for 2.25 to 3.25 hours. Samples of char, gas, water, and organic condensables were collected over a one-hour period from each of these successful tests and analyzed. The effects of process temperature over the range of 1025{degree} to 1390{degree} was studied during this quarter. Compositional effects on the oils and tars observed with increased temperature are increased light oil content, decreased pitch content, decreased oxygen content, increased nitrogen and sulfur content, and increasing aromaticity. Char upgrading studies continued during the quarter. Briquettes made in a laboratory press, using either a pitch binder or Illinois No. 6 coal to provide an in-situ binder, were calcined and tested for diametral compression strength. Char was also subjected to steam activation at a variety of conditions to determine the potential for use as a low-cost absorbent for water treatment. 2 refs., 15 figs., 11 tabs.

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

DOE Green Energy (OSTI)

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.

Development of an advanced, continuous mild gasification process for the production of co-products technical evaluation. Final report  

SciTech Connect

The University of North Dakota Energy and Environmental Research Center (EERC) and the AMAX Research and Development Center are cooperating in the development of a Mild Gasification process that will rapidly devolatilize coals of all ranks at relatively low temperatures between 930{degree} and 1470{degree}F (500{degree}and 800{degree}C) and near atmospheric pressure to produce primary products that include a reactive char, a hydrocarbon condensate, and a low-Btu gas. These will be upgraded in a ``coal refinery`` system having the flexibility to optimize products based on market demand. Task 2 of the four-task development sequence primarily covered bench-scale testing on a 10-gram thermogravimetric analyzer (TGA) and a 1 to 4-lb/hr continuous fluidized-bed reactor (CFBR). Tests were performed to determine product yields and qualities for the two major test coals-one a high-sulfur bituminous coal from the Illinois Basin (Indiana No. 3) and the other a low-sulfur subbituminous coal from the Powder River Basin (Wyodak). Results from Task 3, on product upgrading tests performed by AMAX Research and Development (R&D), are also reported. Task 4 included the construction, operation of a Process Research Unit (PRU), and the upgrading of the products. An economic evaluation of a commercial facility was made, based on the data produced in the PRU, CFBR, and the physical cleaning steps.

Development of an advanced continuous mild gasification process for the production of co-products. Final report, September 1987--September 1996  

SciTech Connect

Char, the major co-product of mild coal gasification, represents about 70 percent of the total product yield. The only viable use for the char is in the production of formed coke. Early work to develop formed coke used char from a pilot plant sized mild gasification unit (MGU), which was based on commercial units of the COALITE plant in England. Formed coke was made at a bench-scale production level using MGU chars from different coals. An evolutionary formed coke development process over a two-year period resulted in formed coke production at bench-scale levels that met metallurgical industries` specifications. In an ASTM D5341 reactivity test by a certified lab, the coke tested CRI 30.4 and CSR 67.0 which is excellent. The standard is CRI < 32 and CSR > 55. In 1991, a continuous 1000 pounds per hour coal feed mild coal gasification pilot plant (CMGU) was completed. The gasification unit is a heated unique screw conveyor designed to continuously process plastic coal, vent volatiles generated by pyrolysis of coal, and convert the plastic coal to free flowing char. The screw reactor auxiliary components are basic solids materials handling equipment. The screw reactor will convert coal to char and volatile co-products at a rate greater than 1000 pounds per hour of coal feed. Formed coke from CMGU char is comparable to that from the MGU char. In pilot-plant test runs, up to 20 tons of foundry coke were produced. Three formed coke tests at commercial foundries were successful. In all of the cupola tests, the iron temperature and composition data indicated that the formed coke performed satisfactorily. No negative change in the way the cupola performed was noticed. The last 20-ton test was 100 percent CTC/DOE coke. With conventional coke in this cupola charging rates were 10 charges per hour. The formed coke charges were 11 to 12 charges per hour. This equates to a higher melt rate. A 10 percent increase in cupola production would be a major advantage. 13 figs., 13 tabs.

A 70-pound continuous coke sample was prepared for testing by a major conventional coke producer. Test results were encouraging, but a suggestion was made to produce larger briquettes. Work is underway to produce 6in. {times} 5in. {times} 3.75in. briquettes with plans to crush these briquettes to plus 2-inch {times} minus 3-inch irregular shaped coke. Work continued to provide a coke reactivity test instrument at CTC. A new vessel was fabricated of Haynes HR-160 which will withstand temperatures up to 2300{degree}F. A total of 11 CMGU test runs were completed. Coal feed rates of over 1000 pounds per hour for short periods were obtained. Average feed rates of over 800 pounds per hour were reached for two test runs. The jet burners heating the insides of the screws` shafts made these higher rates possible. Three test runs were made using 28 {times} 100 mesh Penelec filter cake with the objective of upgrading this coal processing byproduct to coke. Improvements to the PDU continued with two condensers` modifications and improved packing gland seals.

Is the solution to the BCS gap equation continuous in the temperature ?  

E-Print Network (OSTI)

One of long-standing problems in mathematical studies of superconductivity is to show that the solution to the BCS gap equation is continuous in the temperature. In this paper we address this problem. We regard the BCS gap equation as a nonlinear integral equation on a Banach space consisting of continuous functions of both $T$ and $x$. Here, $T (\\geq 0)$ stands for the temperature and $x$ the kinetic energy of an electron minus the chemical potential. We show that the unique solution to the BCS gap equation obtained in our recent paper is continuous with respect to both $T$ and $x$ when $T$ is small enough. The proof is carried out based on the Banach fixed-point theorem.

Downward continuation of temperature gradients at MacFarlane's Hot Spring, Northern Nevada  

SciTech Connect

MacFarlane's Hot Spring is located on the eastern margin of the Black Rock Desert of northwest Nevada. Detailed temperature logs from thirty-eight shallow boreholes (500 feet) and six intermediate depth boreholes (1500-2000 feet) have been used to construct a temperature gradient contour map covering approximately 144 square miles, both within and adjacent to the geothermal area. These temperature gradients were then continued downward through a detailed conductivity model to complete the threedimensional thermal picture. The principal results are as follows: The maximum measured temperature is 178/sup 0/F at 2,000 feet, and the maximum projected temperatures at greater depths are not likely to exceed the 250-350/sup 0/F range. The area of hydrothermal activity is confined to the western front of a structural platform bounded by two roughly parallel normal faults. The anomaly is best explained in terms of a simple groundwater flow model. The groundwater flows west through the structural platform and ascends when it intersects the conduit provided by the fault. The faults on the eastern side of the platform permit recharge to the system.

Low-temperature conversion of high-moisture biomass: Continuous reactor system results  

DOE Green Energy (OSTI)

Pacific Northwest Laboratory (PNL) is developing a low-temperature, catalytic process for converting high-moisture biomass feedstocks and other wet organic substances to useful gaseous fuels. This system, in which thermocatalytic conversion takes place in an aqueous environment, was designed to overcome the problems usually encountered with high-water-content feedstocks. The process uses a reduced nickel catalyst at temperatures as low as 350{degree}C and pressures ranging from 2000 to 4000 psig -- conditions favoring the formation of gas consisting mostly of methane. The results of numerous batch tests showed that the system could convert feedstocks not readily converted by conventional methods. Fifteen tests were conducted in a continuous reactor system to further evaluate the effectiveness of the process for high-moisture biomass gasification and to obtain conversion rate data needed for process scaleup. During the tests, the complex gasification reactions were evaluated by several analytical methods. The results of these tests show that the heating value of the gas ranged from 400 to 500 Btu/scf, and if the carbon dioxide is removed, the product gas is pipeline quality. Conversion of the feedstocks was high. Engineering analysis indicates that, based on these results, a tubular reactor can be designed that should convert greater than 99% of the carbon fed as high-moisture biomass to a gaseous product in a reaction time of less than 11 min.

Reversible Hydrogen Storage using CO2 and a Proton-Switchable Iridium Catalyst in Aqueous Media under Mild Temperatures and Pressures  

Science Conference Proceedings (OSTI)

Green plants convert CO{sub 2} to sugar for energy storage via photosynthesis. We report a novel catalyst that uses CO{sub 2} and hydrogen to store energy in formic acid. Using a homogeneous iridium catalyst with a proton-responsive ligand, we show the first reversible and recyclable hydrogen storage system that operates under mild conditions using CO{sub 2}, formate and formic acid. This system is energy-efficient and green because it operates near ambient conditions, uses water as a solvent, produces high-pressure CO-free hydrogen, and uses pH to control hydrogen production or consumption. The extraordinary and switchable catalytic activity is attributed to the multifunctional ligand, which acts as a proton-relay and strong {pi}-donor, and is rationalized by theoretical and experimental studies.

Low-temperature formation of epitaxial graphene on 6H-SiC induced by continuous electron beam irradiation  

Science Conference Proceedings (OSTI)

It is observed that epitaxial graphene forms on the surface of a 6H-SiC substrate by irradiating electron beam directly on the sample surface in high vacuum at relatively low temperature ({approx}670 Degree-Sign C). The symmetric shape and full width at half maximum of 2D peak in the Raman spectra indicate that the formed epitaxial graphene is turbostratic. The gradual change of the Raman spectra with electron beam irradiation time increasing suggests that randomly distributed small grains of epitaxial graphene form first and grow laterally to cover the entire irradiated area. The sheet resistance of epitaxial graphene film is measured to be {approx}6.7 k{Omega}/sq.

Mathematical modeling of MILD combustion of pulverized coal  

SciTech Connect

MILD (flameless) combustion is a new rapidly developing technology. The IFRF trials have demonstrated high potential of this technology also for N-containing fuels. In this work the IFRF experiments are analyzed using the CFD-based mathematical model. Both the Chemical Percolation Devolatilization (CPD) model and the char combustion intrinsic reactivity model have been adapted to Guasare coal combusted. The flow-field as well as the temperature and the oxygen fields have been accurately predicted by the CFD-based model. The predicted temperature and gas composition fields have been uniform demonstrating that slow combustion occurs in the entire furnace volume. The CFD-based predictions have highlighted the NO{sub x} reduction potential of MILD combustion through the following mechanism. Before the coal devolatilization proceeds, the coal jet entrains a substantial amount of flue gas so that its oxygen content is typically not higher than 3-5%. The volatiles are given off in a highly sub-stoichiometric environment and their N-containing species are preferentially converted to molecular nitrogen rather than to NO. Furthermore, there exists a strong NO-reburning mechanism within the fuel jet and in the air jet downstream of the position where these two jets merge. In other words, less NO is formed from combustion of volatiles and stronger NO-reburning mechanisms exist in the MILD combustion if compared to conventional coal combustion technology. (author)

In the first year of the two- year program, char is being treated with mixtures of H{sub 2} and CH{sub 4} at temperatures of 1100{degrees}C to 1550{degrees}F and pressures of 50 to 100 psig. The effects of temperature, pressure, residence time, gas velocity, and gas composition on sulfur removal and carbon gasification are being determined. The batch experiments are being performed in a nominal 2-inch-ID stainless-steel, batch, fluidized-bed reactor. The char to be desulfurized was produced by the IGT mild gasification process research unit (PRU) in a recently completed DOE/METC-sponsored technology development program. The parent coal was Illinois No. 6 from a preparation plant, and the char from the selected test contains 4.58 wt% sulfur. In the first quarter, we have obtained and prepared a char for the desulfurization tests. Ultimate and proximate analyses were performed on this char, and its pore size distribution and surface area were determined. Also this quarter, the fluidized-bed reactor system was constructed and equipped with high pressure mass flow controllers and a high pressure sintered metal filter to remove fines from the effluent gas stream.

Operational characteristics of a parallel jet MILD combustion burner system  

SciTech Connect

This study describes the performance and stability characteristics of a parallel jet MILD (Moderate or Intense Low-oxygen Dilution) combustion burner system in a laboratory-scale furnace, in which the reactants and exhaust ports are all mounted on the same wall. Thermal field measurements are presented for cases with and without combustion air preheat, in addition to global temperature and emission measurements for a range of equivalence ratio, heat extraction, air preheat and fuel dilution levels. The present furnace/burner configuration proved to operate without the need for external air preheating, and achieved a high degree of temperature uniformity. Based on an analysis of the temperature distribution and emissions, PSR model predictions, and equilibrium calculations, the CO formation was found to be related to the mixing patterns and furnace temperature rather than reaction quenching by the heat exchanger. The critical equivalence ratio, or excess air level, which maintains low CO emissions is reported for different heat exchanger positions, and an optimum operating condition is identified. Results of CO and NO{sub x} emissions, together with visual observations and a simplified two-dimensional analysis of the furnace aerodynamics, demonstrate that fuel jet momentum controls the stability of this multiple jet system. A stability diagram showing the threshold for stable operation is reported, which is not explained by previous stability criteria. (author)

CONTINUOUSLY SENSITIVE BUBBLE CHAMBER  

DOE Patents (OSTI)

A radiation detector of the bubble chamber class is described which is continuously sensitive and which does not require the complex pressure cycling equipment characteristic of prior forms of the chamber. The radiation sensitive element is a gas-saturated liquid and means are provided for establishing a thermal gradient across a region of the liquid. The gradient has a temperature range including both the saturation temperature of the liquid and more elevated temperatures. Thus a supersaturated zone is created in which ionizing radiations may give rise to visible gas bubbles indicative of the passage of the radiation through the liquid. Additional means are provided for replenishing the supply of gas-saturated liquid to maintaincontinuous sensitivity.

Mild coal pretreatment to improve liquefaction reactivity  

SciTech Connect

This report describes work completed during the fourth quarter of a three year project to study the effects of mild chemical pretreatment on coal dissolution reactivity during low severity liquefaction or coal/oil coprocessing. The overall objective of this research is to elucidate changes in the chemical and physical structure of coal by pretreating with methanol or other simple organic solvent and a trace amount of hydrochloric acid and measure the influence of these changes on coal dissolution reactivity. This work is part of a larger effort to develop a new coal liquefaction or coal/oil coprocessing scheme consisting of three main process steps: (1) mile pretreatment of the feed coal to enhance dissolution reactivity and dry the coal, (2) low severity thermal dissolution of the pretreated coal to obtain a very reactive coal-derived residual material amenable to upgrading, and (3) catalytic upgrading of the residual products to distillate liquids.

Development of an advanced, continuous mild gasification process for the production of co-products  

SciTech Connect

The principal finding of this study was the high capital cost and poor financial performance predicted for the size and configuration of the plant design presented. The XBi financial assessment gave a disappointingly low base-case discounted cash flow rate of return (DCFRR) of only 8.1% based on a unit capital cost of $900 per ton year (tpy) for their 129,000 tpy design. This plant cost is in reasonable agreement with the preliminary estimates developed by J.E. Sinor Associates for a 117,000 tpy plant based on the FMC process with similar auxiliaries (Sinor, 1989), for which a unit capital costs of $938 tpy was predicted for a design that included char beneficiation and coal liquids upgrading--or about $779 tpy without the liquid upgrading facilities. The XBi assessment points out that a unit plant cost of $900 tpy is about three times the cost for a conventional coke oven, and therefore, outside the competitive range for commercialization. Modifications to improve process economics could involve increasing plant size, expanding the product slate that XBi has restricted to form coke and electricity, and simplifying the plant flow sheet by eliminating marginally effective cleaning steps and changing other key design parameters. Improving the financial performance of the proposed formed coke design to the level of a 20% DCFRR based on increased plant size alone would require a twenty-fold increase to a coal input of 20,000 tpd and a coke production of about 2.6 minion tpy--a scaling exponent of 0.70 to correct plant cost in relation to plant size.

DOE Patents (OSTI)

A reagent gas and a sample gas are chemically combined on a continuous basis in a reaction zone maintained at a selected temperature. The reagent gas and the sample gas are introduced to the reaction zone at preselected. constant molar rates of flow. The reagent gas and the selected gas in the sample mixture combine in the reaction zone to form a product gas having a different number of moles from the sum of the moles of the reactants. The difference in the total molar rates of flow into and out of the reaction zone is measured and indicated to determine the concentration of the selected gas.

ENCOAL mild coal gasification project public design and construction report  

SciTech Connect

This Public Design Report describes the 1000 ton per day ENCOAL mild coal gasification demonstration plant now in operation at the Buckskin Mine near Gillette, Wyoming. The objective of the project is to demonstrate that the proprietary Liquids From Coal (LFC) technology can reliably and economically convert low Btu PRB coal into a superior, high-Btu solid fuel (PDF), and an environmentally attractive low-sulfur liquid fuel (CDL). The Project`s plans also call for the production of sufficient quantities of PDF and CDL to permit utility companies to carry out full scale burn tests. While some process as well as mechanical design was done in 1988, the continuous design effort was started in July 1990. Civil construction was started in October 1990; mechanical erection began in May 1991. Virtually all of the planned design work was completed by July 1991. Most major construction was complete by April 1992 followed by plant testing and commissioning. Plant operation began in late May 1992. This report covers both the detailed design and initial construction aspects of the Project.

Mild coal pretreatment to improve liquefaction reactivity

This report describes work completed during the fifth quarter of a three year project to study the effects of mild chemical pretreatment on coal dissolution reactivity during low severity liquefaction or coal/oil coprocessing. The overall objective of this research is to elucidate changes in the chemical and physical structure of coal by pretreating with methanol or other simple organic solvent and a trace amount of hydrochloric acid and measure the influence of these changes on coal dissolution reactivity. Work this quarter focused on analytical characterization of untreated and treated Wyodak subbituminous coal and Illinois {number sign}6 bituminous coal. Mossbauer spectroscopy and x-ray diffraction techniques were used to study the effect of methanol/HCl pretreatment on the composition of each coal's inorganic phase. Results from these studies indicated that calcite is largely removed during pretreatment, but that other mineral species such as pyrite are unaffected. This finding is significant, since calcite removal appears to directly correlate with low severity liquefaction enhancement. Further work will be performed to study this phenomenon in more detail.

Solvolytic liquefaction of wood under mild conditions  

DOE Green Energy (OSTI)

Conversion of wood to liquid products requires cleavage of bonds which crosslink the wood structure. This study examines a low-severity wood solubilization process utilizing a solvent medium consisting of a small amount of sulfuric acid and a potentially wood-derivable alcohol. In one half hour of reaction time at 250/sup 0/C under 15 psia starting nitrogen pressure, over 95% of the wood (maf) was rendered acetone-soluble. The product is a soft, black, bitumen-like solid at room temperature but readily softens at 140/sup 0/C. Between 25 and 50% of the original wood oxygen, depending on alcohol used, was removed as water. Approximately 2 to 17% of the alcohols were retained in the product. Gel permeation chromatography showed that the product's median molecular weight is around 300. Based on experimental and literature results, a mechanism for wood solubilization is proposed. This involves protonation of the etheric oxygen atoms, leading to subsequent bond scission to form carbonium ions which are stabilized by solvent alkoxylation. At severe conditions, polymerization and condensation reactions result in acetone-insoluble materials.

Use of Electrochemical Noise to Assess Corrosion in Kraft Continuous Digesters  

DOE Green Energy (OSTI)

Electrochemical noise (EN) probes were deployed in two continuous kraft digesters at a variety of locations representative of corrosion throughout the vessels. Current and potential noise, the temperature at each probe location, and the value of up to 60 process parameters (flow rates, liquor chemistry, etc.) were monitored continuously during each experiment. The results indicate that changes in furnish composition and process upsets were invariably associated with concurrent substantial changes in EN activity throughout the vessels. Post-test evaluation of the mild steel electrode materials in both vessels confirmed general corrosion of a magnitude consistent with historical trends in the respective vessels as well as values qualitatively (and semi-quantitatively) related to EN current sums for each electrode pair. Stainless steel electrodes representing 309LSi and 312 overlay repairs exhibited zero wastage corrosion--as did the actual overlays--but the EN data indicated periodic redox activity on the stainless steel that varied with time and position within the vessel. Little or no correlation between EN probe activity and other operational variables was observed in either vessel. Additional details for each digester experiment are summarized.

Global warming continues in 1989  

SciTech Connect

Nineteen eight-nine ranks as one of the warmest years on record despite the chill of unusually cool water in the tropical Pacific. The continued robustness of the warming trend that began in the mid-1970s lends support to claims that an intensifying greenhouse effect is behind it all, although that case has not yet been made definitively. Even at the current rate of global warming it will take another 10 years or so to be confident that the greenhouse effect is with us. Although the global warming trend is consistent with an increasing contribution by the greenhouse effect, direct signs that the greenhouse effect is intensifying are still hard to come by in the temperature record. Greenhouse models agree that if that is happening, the temperature increase should be most pronounced around the Arctic. Alaska, northwestern Canada, and northern Siberia warmed sharply in the 1980s, but the region from eastern Canada through Greenland and into Scandinavia cooled markedly.

Scale-up of mild gasification to a process development unit. Quarterly report, May 21--August 20, 1993  

SciTech Connect

The work performed during the seventh quarterly reporting period on the research program, ``Scale-up of Mild Gasification to a Process Development Unit`` is presented in this report. The overall objective of this project is to develop the IGT Mild-Gasification (MILDGAS) process for near-term commercialization. The specific objectives of the program are to: (1) design, construct, and operate a 24-tons/day adiabatic process development unit (PDU) to obtain process performance data suitable for further design scaleup. (2) Obtain large batches of coal-derived co-products for industrial evaluation. (3) Prepare a detailed design of a demonstration unit. And (4) develop technical and economic plans for commercialization of the MILDGAS process. The MILDGAS process is a continuous closed system for producing liquid and solid (char) co-products at mild operating conditions up to 50 psig and 1300{degree}F. It is capable of processing a wide range of both eastern caking and western noncaking coals. The 1 ton/hr PDU facility is comprised of a 2.5-ft ID adiabatic gasifier for the production of gases, coal liquids, and char; a thermal cracker for upgrading of the coal liquids; a three-stage condensation train to condense and store the liquid products; and coal feeding and char handling equipment. The facility will also incorporate support equipment for environmentally acceptable disposal of process waste.

Autoignited laminar lifted flames of propane in coflow jets with tribrachial edge and mild combustion  

Science Conference Proceedings (OSTI)

Characteristics of laminar lifted flames have been investigated experimentally by varying the initial temperature of coflow air over 800 K in the non-premixed jets of propane diluted with nitrogen. The result showed that the lifted flame with the initial temperature below 860 K maintained the typical tribrachial structure at the leading edge, which was stabilized by the balance mechanism between the propagation speed of tribrachial flame and the local flow velocity. For the temperature above 860 K, the flame was autoignited without having any external ignition source. The autoignited lifted flames were categorized in two regimes. In the case with tribrachial edge structure, the liftoff height increased nonlinearly with jet velocity. Especially, for the critical condition near blowout, the lifted flame showed a repetitive behavior of extinction and reignition. In such a case, the autoignition was controlled by the non-adiabatic ignition delay time considering heat loss such that the autoignition height was correlated with the square of the adiabatic ignition delay time. In the case with mild combustion regime at excessively diluted conditions, the liftoff height increased linearly with jet velocity and was correlated well with the square of the adiabatic ignition delay time.

Method for the continuous production of hydrogen  

DOE Green Energy (OSTI)

The present invention is a method for the continuous production of hydrogen. The present method comprises reacting a metal catalyst with a degassed aqueous organic acid solution within a reaction vessel under anaerobic conditions at a constant temperature of .ltoreq.80.degree. C. and at a pH ranging from about 4 to about 9. The reaction forms a metal oxide when the metal catalyst reacts with the water component of the organic acid solution while generating hydrogen, then the organic acid solution reduces the metal oxide thereby regenerating the metal catalyst and producing water, thus permitting the oxidation and reduction to reoccur in a continual reaction cycle. The present method also allows the continuous production of hydrogen to be sustained by feeding the reaction with a continuous supply of degassed aqueous organic acid solution.

The ENCOAL Mild Coal Gasification Project, A DOE Assessment  

Science Conference Proceedings (OSTI)

This report is a post-project assessment of the ENCOAL{reg_sign} Mild Coal Gasification Project, which was selected under Round III of the U.S. Department of Energy (DOE) Clean Coal Technology (CCT) Demonstration Program. The CCT Demonstration Program is a government and industry cofunded technology development effort to demonstrate a new generation of innovative coal utilization processes in a series of commercial-scale facilities. The ENCOAL{reg_sign} Corporation, a wholly-owned subsidiary of Bluegrass Coal Development Company (formerly SMC Mining Company), which is a subsidiary of Ziegler Coal Holding Company, submitted an application to the DOE in August 1989, soliciting joint funding of the project in the third round of the CCT Program. The project was selected by DOE in December 1989, and the Cooperative Agreement (CA) was approved in September 1990. Construction, commissioning, and start-up of the ENCOAL{reg_sign} mild coal gasification facility was completed in June 1992. In October 1994, ENCOAL{reg_sign} was granted a two-year extension of the CA with the DOE, that carried through to September 17, 1996. ENCOAL{reg_sign} was then granted a six-month, no-cost extension through March 17, 1997. Overall, DOE provided 50 percent of the total project cost of $90,664,000. ENCOAL{reg_sign} operated the 1,000-ton-per-day mild gasification demonstration plant at Triton Coal Company's Buckskin Mine near Gillette, Wyoming, for over four years. The process, using Liquids From Coal (LFC{trademark}) technology originally developed by SMC Mining Company and SGI International, utilizes low-sulfur Powder River Basin (PRB) coal to produce two new fuels, Process-Derived Fuel (PDF{trademark}) and Coal-Derived Liquids (CDL{trademark}). The products, as alternative fuel sources, are capable of significantly lowering current sulfur emissions at industrial and utility boiler sites throughout the nation thus reducing pollutants causing acid rain. In support of this overall objective, the following goals were established for the ENCOAL{reg_sign} Project: Provide sufficient quantity of products for full-scale test burns; Develop data for the design of future commercial plants; Demonstrate plant and process performance; Provide capital and O&M cost data; and Support future LFC{trademark} technology licensing efforts. Each of these goals has been met and exceeded. The plant has been in operation for nearly 5 years, during which the LFC{trademark} process has been demonstrated and refined. Fuels were made, successfully burned, and a commercial-scale plant is now under contract for design and construction.

Encoal mild coal gasification project: Final design modifications report  

Science Conference Proceedings (OSTI)

The design, construction and operation Phases of the Encoal Mild Coal Gasification Project have been completed. The plant, designed to process 1,000 ton/day of subbituminous Power River Basin (PRB) low-sulfur coal feed and to produce two environmentally friendly products, a solid fuel and a liquid fuel, has been operational for nearly five years. The solid product, Process Derived Fuel (PDF), is a stable, low-sulfur, high-Btu fuel similar in composition and handling properties to bituminous coal. The liquid product, Coal Derived Liquid (CDL), is a heavy, low-sulfur, liquid fuel similar in properties to heavy industrial fuel oil. Opportunities for upgrading the CDL to higher value chemicals and fuels have been identified. Significant quantities of both PDF and CDL have been delivered and successfully burned in utility and industrial boilers. A summary of the Project is given.

Investigation of a technique for sulfur reduction of mild gasification char. Technical report, March 1--May 31, 1992  

DOE Green Energy (OSTI)

The object of this program is to investigate the desulfurization of mild gasification char using H{sub 2}:CH{sub 4} mixtures at the laboratory scale. Mild gasification is a coal conversion technique which produces solid, liquid, and gaseous co-products at 1100{degrees}--1500{degrees}F and near-ambient pressure. Char comprises about 60 to 70% of the dry coal yield. Form coke for steelmaking and foundries presents potential high-value markets for chars from eastern bituminous coals. Conventional metallurgical cokes generally contain less than 1 wt% sulfur, and mild gasification char from high-sulfur Illinois coals must be upgraded to meet these criteria. One method to accomplish this is desulfurization with reducing gases derived from the co-product gases. Because form coke has a market value up to $200/ton, it can accommodate desulfurization costs and still be economically attractive. In the first year of the two-year program, granular char is being treated with H{sub 2}:CH{sub 4} blends at temperatures of 1100{degrees}--1600{degrees}F and pressures of 50--200 psig. The effects of temperature, pressure, residence time, gas velocity, and gas composition on sulfur removal and carbon gasification are being determined. During the third quarter, 10 tests were performed with four chars. Fluidized-bed tests were conducted at 1400--1600{degrees}F, 50--200 psig, and 120--240 min residence time. Future tests will focus on determining the key properties that determine the susceptibility of char to hydrodesulfurization with minimal carbon conversion.

Ohno continuous casting  

SciTech Connect

Production of net-shape products directly from the liquid is an attractive manufacturing route for alloys that are difficult to process or that cannot be rolled, drawn, or extruded. Developed at the Chiba Institute of Technology in Japan, the Ohno Continuous Casting (OCC) approach not only provides significant cost savings, but also has the potential to create new products. OCC process equipment includes a melting furnace, crucible, mold level-control block, cooling device, and pinch rolls. OCC is currently used to produce copper rods and wires for audio and video cables, and aluminum alloy welding rods for hard-surfacing applications. For example, Mitsui Engineering and Ship Building Co. has used OCC to produce copper tubing products with internal fins and partitions for applications such as heat exchanger tubes and induction coils.

Nonlinear continuous feedback controllers  

E-Print Network (OSTI)

Packet-switched communication networks such as today's Internet are built with several interconnected core and distribution packet forwarding routers and several sender and sink transport agents. In order to maintain stability and avoid congestion collapse in the network, the sources control their rate behavior and voluntarily adjust their sending rates to accommodate other sources in the network. In this thesis, we study one class of sender rate control that is modeled using continuous first-order differential equation of the sending rates. In order to adjust the rates appropriately, the network sends continuous packet-loss feedback to the sources. We study a form of closed-loop feedback congestion controllers whose rate adjustments exhibit a nonlinear form. There are three dimensions to our work in this thesis. First, we study the network optimization problem in which sources choose utilities to maximize their underlying throughput. Each sender maximizes its utility proportional to the throughput achieved. In our model, sources choose a utility function to define their level of satisfaction of the underlying resource usages. The objective of this direction is to establish the properties of source utility functions using inequality constrained bounded sets and study the functional forms of utilities against a chosen rate differential equation. Second, stability of the network and tolerance to perturbation are two essential factors that keep communication networks operational around the equilibrium point. Our objective in this part of the thesis is to analytically understand the existence of local asymptotic stability of delayed-feedback systems under homogeneous network delays. Third, we propose a novel tangential controller for a generic maximization function and study its properties using nonlinear optimization techniques. We develop the necessary theoretical background and the properties of our controller to prove that it is a better rate adaptation algorithm for logarithmic utilities compared to the well-studied proportional controllers. We establish the asymptotic local stability of our controller with upper bounds on the increase / decrease gain parameters.

Investigation of a sulfur reduction technique for mild gasification char. Technical report, September 1, 1991--November 30, 1991  

DOE Green Energy (OSTI)

The object of this program is to investigate the desulfurization of mild gasification char using hydrogen/methane mixtures in a laboratory-scale experimental study. In the first year of the two- year program, char is being treated with mixtures of H{sub 2} and CH{sub 4} at temperatures of 1100{degrees}C to 1550{degrees}F and pressures of 50 to 100 psig. The effects of temperature, pressure, residence time, gas velocity, and gas composition on sulfur removal and carbon gasification are being determined. The batch experiments are being performed in a nominal 2-inch-ID stainless-steel, batch, fluidized-bed reactor. The char to be desulfurized was produced by the IGT mild gasification process research unit (PRU) in a recently completed DOE/METC-sponsored technology development program. The parent coal was Illinois No. 6 from a preparation plant, and the char from the selected test contains 4.58 wt% sulfur. In the first quarter, we have obtained and prepared a char for the desulfurization tests. Ultimate and proximate analyses were performed on this char, and its pore size distribution and surface area were determined. Also this quarter, the fluidized-bed reactor system was constructed and equipped with high pressure mass flow controllers and a high pressure sintered metal filter to remove fines from the effluent gas stream.

Upgrading mild gasification liquids to produce electrode binder pitch: Final technical report, September 1, 1993--October 31, 1994  

DOE Green Energy (OSTI)

The objective of this program is to investigate the production of electrode binder pitch, valued at $250--$300/ton, from mild gasification liquids. In the IGT MILDGAS process, the 400 C+ distillation residue (crude pitch) comprises up to 20 wt% of maf feed coal. The largest market for pitch made from coal liquids is the aluminum industry, which uses it to make carbon anodes for electrolytic furnaces. In this project, crude MILDGAS pitch is being modified by flash thermocracking to achieve binder pitch specifications. A 1-kg/h continuous unit has been built for operation up to 900 C at 2.5 atm, and parametric tests were conducted in N{sub 2}, H{sub 2} and 50% H{sub 2}/N{sub 2}. In general, thermocracking at 750--850 C in N{sub 2} resulted in a pitch which meets binder pitch requirements for QI, TI, softening point, and C:H ratio. Further improvements in density and sulfur content are required. Test anodes were prepared by Alcoa using the upgraded mild gasification pitch. All of the key anode properties (density, strength, resistivity, thermal properties, permeability, and reactivity) compared very favorably with those of electrodes made from a standard pitch binder.

Mild Catalytic methods for Alkyl-Alkyl Bond Formation  

DOE Green Energy (OSTI)

Overview of Research Goals and Accomplishments for the Period 07/01/06 06/30/07: Our overall research goal is to transform the rapidly emerging synthetic chemistry involving alkyl-alkyl cross-couplings into more of a mechanism-based field so that that new, rationally-designed catalysts can be performed under energy efficient conditions. Our specific objectives for the previous year were 1) to obtain a proper electronic description of an active catalyst for alkyl-alkyl cross-coupling reactions and 2) to determine the effect of ligand structure on the rate, scope, selectivity, and functional group compatibility of C(sp3)-C(sp3) cross-coupling catalysis. We have completed both of these initial objectives and established a firm base for further studies. The specific significant achievements of the current grant period include: 1) we have performed magnetic and computational studies on (terpyridine)NiMe, an active catalyst for alkyl-alkyl cross couplings, and have discovered that the unpaired electron resides heavily on the terpyridine ligand and that the proper electronic description of this nickel complex is a Ni(II)-methyl cation bound to a reduced terpyridine ligand; 2) we have for the first time shown that alkyl halide reduction by terpyridyl nickel catalysts is substantially ligand based; 3) we have shown by isotopic labeling studies that the active catalyst (terpyridine)NiMe is not produced via a mechanism that involves the formation of methyl radicals when (TMEDA)NiMe2 is used as the catalyst precursor; 4) we have performed an extensive ligand survey for the alkyl-alkyl cross-coupling reactions and have found that electronic factors only moderately influence reactivity in the terpyridine-based catalysis and that the most dramatic effects arise from steric and solubility factors; 5) we have found that the use of bis(dialkylphosphino)methanes as ligands for nickel does not produce active catalysts for cross-coupling but rather leads to bridging hydride complexes of varying geometries; 6) we have determined that the geometry of aforementioned bridging hydride complexes is largely determined by external forces such as hydrogen bonding interactions and crystal packing forces; 7) we have found that the rate of reductive elimination of alkane from a (pyridyl-2-pyrrolide)AuMe2 complex is severely inhibited due to the rigid geometry of the pyridyl-2-pyrrolide ligand; 8) we have prepared, structurally characterized, and explored the reactivity of 1-adamantylzinc reagents as model nucleophiles for sterically challenging alkyl-alkyl cross-coupling reactions. The continued success of this work will lead to alkyl-alkyl cross-coupling catalysts with broad scope and selectivities. The work has potential to significantly impact science and technologies of interest to the DOE as the chemistry is focused on developing useful reactions using reagents that can be directly prepared from petroleum and natural gas feedstocks. Moreover, the developing synthetic chemistry can profoundly affect the way materials, fine chemicals, and drugs are made. Since the methodology we are developing can shorten existing synthetic protocols, proceed at room temperature, and operate under environmentally benign conditions, it can greatly reduce energy expenditures, especially considering the contribution of the chemical manufacturing field to the gross domestic product.

Biodesulfurization of mild gasification liquid products. Final technical report, 1 September, 1992--31 August, 1993  

Science Conference Proceedings (OSTI)

The mild gasification of coal, as being developed at IGT and elsewhere, is a promising new technology that can convert coal to multiple products: gas, solid, and liquids. Mild gasification liquids can be used as feedstock to make transportation fuels and chemicals. However, the sulfur content and aromaticity of mild gasification liquids limits their usefulness and biodesulfurization can potentially decrease both sulfur content and aromaticity. The objective of this project is to investigate and feasibility of using biodesulfurization to upgrade the quality of mild gasification liquids. During this project, it was shown that the middle distillate (360--440 F) fraction of liquids derived from the mild gasification of coal, and unfractionated liquids can be biodesulfurized. Moreover, it was demonstrated that lysed cell preparations and freeze-dried cells can be used to biodesulfurize mild coal gasification liquids. The importance of the finding that freeze-dried biocatalysts can be used to biodesulfurize mild coal gasification liquids is that freeze-dried cells can be produced at one location, stored indefinitely, and then shipped (at reduced weight, volume, and cost) to another location for coal biodesulfurization. Moreover, freeze-dried biocatalysts can be added directly to mild coal gasification liquids with only minimal additions of water so that reactor volumes can be minimized.

Continuous Box game  

E-Print Network (OSTI)

The classical positional game Box was introduced by Chvtal and Erd?s in 1978 in their study of the biased connectivity game on the complete graph. Their analysis was subsequently extended by Hamidoune and Las Vergnas. The board of the Box game consists of elements of n disjoint sets (boxes), which might vary in size. The game is played by two players, Maker and Breaker. Maker claims m board elements per move whereas Breaker claims just one. Maker wins this game if and only if he claims all elements of some box by the end of the game. In this paper we introduce the game CBox, a continuous version of the Box game, where the sizes of the boxes need not be integral and in every move Maker puts a nonnegative real weight into each box, such that the weights sum up to the real number m. This new game, while closely related to the original Box game, turns out to be more amenable to analysis we derive explicit and easy to use criteria for determining the winner in every instance of the game. Consequently, establishing a connection between CBox and Box, we also obtain applicable criteria for the Box game. 1

During the year, 23 tests were performed with 10 chars. Fluidized-bed tests were conducted for 120 to 240 minutes with superficial gas velocities from 0.067 to 0.150 ft/s. The desulfurization medium was H{sub 2} gas containing 9 to 24 vol% CH{sub 4}. The data from these tests show sulfur conversions ranging from 6.0 to 92.5 wt%, with carbon conversions from zero to 35.3 wt%. The maximum sulfur conversion was 92.5 wt% at 1400{degree}F and 200 psig in 76% H, for 120 minutes residence time, using IFFR char produced from IBC-106 coal at 1200{degree}F in helium.

Scale-up of mild gasification to a process development unit. Quarterly report, May--August 1993  

SciTech Connect

The overall objective of this project is to develop the IGT Mild-Gasification (MILDGAS) process for near-term commercialization. The specific objectives of the program are to: design, construct, and operate a 24-tons/day adiabatic process development unit (PDU) to obtain process performance data suitable for further design scaleup; obtain large batches of coal-derived co-products for industrial evaluation; prepare a detailed design of a demonstration unit; and develop technical and economic plans for commercialization of the MILDGAS process. The MILDGAS process is a continuous closed system for producing liquid and solid (char) co-products at mild operating conditions up to 50 psig and 1300 F. It is capable of processing a wide range of both eastern caking and western noncaking coals. The 1 ton/hr PDU facility that is to be constructed is comprised of a 2.5-ft ID adiabatic gasifier for the production of gases, coal liquids, and char; a thermal cracker for upgrading of the coal liquids; a three-stage condensation train to condense and store the liquid products; and coal feeding and char handling equipment. The facility will also incorporate support equipment for environmentally acceptable disposal of process waste. This quarter, the authors completed preparation of the draft of the permitting documentation that will be required by the Illinois EPA for the permit to construct the PDU and it is planned to submit it to the State of Illinois early in the next quarter. Also this quarter, a presentation of the project aims and status were presented during a site visit on August 11, 1993 by DOE personnel and Robert Kripowicz, the Staff Assistant, Subcommittee on the Interior, of the US House Committee on Appropriations.

Mercury Continuous Emmission Monitor Calibration  

SciTech Connect

Mercury continuous emissions monitoring systems (CEMs) are being implemented in over 800 coal-fired power plant stacks throughput the U.S. Western Research Institute (WRI) is working closely with the Electric Power Research Institute (EPRI), the National Institute of Standards and Technology (NIST), and the Environmental Protection Agency (EPA) to facilitate the development of the experimental criteria for a NIST traceability protocol for dynamic elemental mercury vapor calibrators/generators. These devices are used to calibrate mercury CEMs at power plant sites. The Clean Air Mercury Rule (CAMR) which was published in the Federal Register on May 18, 2005 and vacated by a Federal appeals court in early 2008 required that calibration be performed with NIST-traceable standards. Despite the vacature, mercury emissions regulations in the future will require NIST traceable calibration standards, and EPA does not want to interrupt the effort towards developing NIST traceability protocols. The traceability procedures will be defined by EPA. An initial draft traceability protocol was issued by EPA in May 2007 for comment. In August 2007, EPA issued a conceptual interim traceability protocol for elemental mercury calibrators. The protocol is based on the actual analysis of the output of each calibration unit at several concentration levels ranging initially from about 2-40 {micro}g/m{sup 3} elemental mercury, and in the future down to 0.2 {micro}g/m{sup 3}, and this analysis will be directly traceable to analyses by NIST. The EPA traceability protocol document is divided into two separate sections. The first deals with the qualification of calibrator models by the vendors for use in mercury CEM calibration. The second describes the procedure that the vendors must use to certify the calibrators that meet the qualification specifications. The NIST traceable certification is performance based, traceable to analysis using isotope dilution inductively coupled plasma/mass spectrometry (ID/ICP/MS) performed by NIST in Gaithersburg, MD. The outputs of mercury calibrators are compared to one another using a nesting procedure which allows direct comparison of one calibrator with another at specific concentrations and eliminates analyzer variability effects. The qualification portion of the EPA interim traceability protocol requires the vendors to define calibrator performance as affected by variables such as pressure, temperature, line voltage, and shipping. In 2007 WRI developed and conducted a series of simplified qualification experiments to determine actual calibrator performance related to the variables defined in the qualification portion of the interim protocol.

LANL continuity of operations plan  

SciTech Connect

The Los Alamos National Laboratory (LANL) is a premier national security research institution, delivering scientific and engineering solutions for the nation's most crucial and complex problems. Our primary responsibility is to ensure the safety, security, and reliability of the nation's nuclear stockpile. LANL emphasizes worker safety, effective operational safeguards and security, and environmental stewardship, outstanding science remains the foundation of work at the Laboratory. In addition to supporting the Laboratory's core national security mission, our work advances bioscience, chemistry, computer science, earth and environmental sciences, materials science, and physics disciplines. To accomplish LANL's mission, we must ensure that the Laboratory EFs continue to be performed during a continuity event, including localized acts of nature, accidents, technological or attack-related emergencies, and pandemic or epidemic events. The LANL Continuity of Operations (COOP) Plan documents the overall LANL COOP Program and provides the operational framework to implement continuity policies, requirements, and responsibilities at LANL, as required by DOE 0 150.1, Continuity Programs, May 2008. LANL must maintain its ability to perform the nation's PMEFs, which are: (1) maintain the safety and security of nuclear materials in the DOE Complex at fixed sites and in transit; (2) respond to a nuclear incident, both domestically and internationally, caused by terrorist activity, natural disaster, or accident, including mobilizing the resources to support these efforts; and (3) support the nation's energy infrastructure. This plan supports Continuity of Operations for Los Alamos National Laboratory (LANL). This plan issues LANL policy as directed by the DOE 0 150.1, Continuity Programs, and provides direction for the orderly continuation of LANL EFs for 30 days of closure or 60 days for a pandemic/epidemic event. Initiation of COOP operations may be required to support an allhazards event, including a national security emergency, major fire, catastrophic natural disaster, man-made disaster, terrorism event, or technological disaster by rendering LANL buildings, infrastructure, or Technical Areas unsafe, temporarily unusable, or inaccessible.

Quantum kinetic theory model of a continuous atom laser  

E-Print Network (OSTI)

We investigate the feasible limits for realising a continuously evaporated atom laser with high-temperature sources. A plausible scheme for realising a truly continuous atom laser is to outcouple atoms from a partially condensed Bose gas, whilst continuously reloading the system with non-condensed thermal atoms and performing evaporative cooling. Here we use quantum kinetic theory to model this system and estimate feasible limits for the operation of such a scheme. For sufficiently high temperatures, the figure of merit for the source is shown to be the phase-space flux. The dominant process limiting the usage of sources with low phase-space flux is the three-body loss of the condensed gas. We conclude that certain double-magneto-optical trap (MOT) sources may produce substantial mean condensate numbers through continuous evaporation, and provide an atom laser source with a narrow linewidth and reasonable flux.

Continuous production of polymethylpentene membranes  

DOE Patents (OSTI)

Gas separation membranes may be prepared in a continuous manner by passing a porous support which may, if so desired, be backed by a fabric through a solution of polymethylpentene dissolved in an organic solvent such as hexane. The support member is passed through the solution while one side thereof is in contact with a roller, thereby permitting only one side of the support member to be coated with the polymer. After continuously withdrawing the support member from the bath, the solvent is allowed to evaporate and the resulting membrane is recovered.

Low temperature hydrothermal processing of organic contaminants in Hanford tank waste  

DOE Green Energy (OSTI)

Batch and continuous flow reactor tests at Pacific Northwest Laboratory (PNL) have shown that organics similar to those present in the single-shell and double-shell underground storage tanks at Hanford can be decomposed in the liquid phase at relatively mild temperatures of 150[degree]C to 350[degree]C in an aqueous process known as hydrothermal processing (HTP). The organics will react with the abundant oxidants such s nitrite already present in the Hanford tank waste to form hydrogen, carbon dioxide, methane, and ammonia. No air or oxygen needs to be added to the system. Ferrocyanides and free cyanide will hydrolyze at similar temperatures to produce formate and ammonia and may also react with nitrates or other oxides. During testing, the organic carbon was transformed first to oxalate at[approximately]310[degree]C and completely oxidized to carbonate at [approximately]350[degree]C accompanied by hydroxide consumption. Solids were formed at higher temperatures, causing a small-diameter outlet tube to plug. The propensity for plugging was reduced by diluting the feed with concentrated hydroxide.

Continuous emission monitor for incinerators  

Science Conference Proceedings (OSTI)

This paper describes the development of Fourier transform infrared (FTIR) spectroscopy to continuous monitoring of incinerator emissions. Fourier transform infrared spectroscopy is well suited to this application because it can identify and quantify selected target analytes in a complex mixture without first separating the components in the mixture. Currently, there is no on-stream method to determine the destruction of hazardous substances, such as benzene, or to continuously monitor for hazardous products of incomplete combustion (PICs) in incinerator exhaust emissions. This capability is especially important because of Federal regulations in the Clean Air Act of 1990, which requires the monitoring of air toxics (Title III), the Resource Conservation and Recovery Act (RCRA), and the Toxic Substances Control Act (TSCA). An on-stream continuous emission monitor (CEM) that can differentiate species in the ppm and ppb range and can calculate the destruction and removal efficiency (DRE) could be used to determine the safety and reliability of incinerators. This information can be used to address reasonable public concern about incinerator safety and aid in the permitting process.

Continuous Precipitation of Ceria Nanoparticles from a Continuous Flow Micromixer  

SciTech Connect

Cerium oxide nanoparticles were continuously precipitated from a solution of cerium(III) nitrate and ammonium hydroxide using a micro-scale T-mixer. Findings show that the method of mixing is important in the ceria precipitation process. In batch mixing and deposition, disintegration and agglomeration dominates the deposited film. In T-mixing and deposition, more uniform nanorod particles are attainable. In addition, it was found that the micromixing approach reduced the exposure of the Ce(OH)3 precipates to oxygen, yielding hydroxide precipates in place of CeO2 precipitates. Advantages of the micro-scale T-mixing approach include shorter mixing times, better control of nanoparticle shape and less agglomeration.

Development of an advanced, continuous mild gasification process for the production of co-products. Task 4.6, Economic evaluation  

SciTech Connect

The principal finding of this study was the high capital cost and poor financial performance predicted for the size and configuration of the plant design presented. The XBi financial assessment gave a disappointingly low base-case discounted cash flow rate of return (DCFRR) of only 8.1% based on a unit capital cost of $900 per ton year (tpy) for their 129,000 tpy design. This plant cost is in reasonable agreement with the preliminary estimates developed by J.E. Sinor Associates for a 117,000 tpy plant based on the FMC process with similar auxiliaries (Sinor, 1989), for which a unit capital costs of $938 tpy was predicted for a design that included char beneficiation and coal liquids upgrading--or about $779 tpy without the liquid upgrading facilities. The XBi assessment points out that a unit plant cost of $900 tpy is about three times the cost for a conventional coke oven, and therefore, outside the competitive range for commercialization. Modifications to improve process economics could involve increasing plant size, expanding the product slate that XBi has restricted to form coke and electricity, and simplifying the plant flow sheet by eliminating marginally effective cleaning steps and changing other key design parameters. Improving the financial performance of the proposed formed coke design to the level of a 20% DCFRR based on increased plant size alone would require a twenty-fold increase to a coal input of 20,000 tpd and a coke production of about 2.6 minion tpy--a scaling exponent of 0.70 to correct plant cost in relation to plant size.

High-bandwidth continuous-flow arc furnace  

DOE Patents (OSTI)

A high-bandwidth continuous-flow arc furnace for stream welding applications includes a metal mass contained in a crucible having an orifice. A power source charges an electrode for generating an arc between the electrode and the mass. The arc heats the metal mass to a molten state. A pressurized gas source propels the molten metal mass through the crucible orifice in a continuous stream. As the metal is ejected, a metal feeder replenishes the molten metal bath. A control system regulates the electrode current, shielding gas pressure, and metal source to provide a continuous flow of molten metal at the crucible orifice. Independent control over the electrode current and shield gas pressure decouples the metal flow temperature and the molten metal flow rate, improving control over resultant weld characteristics. 4 figs.

Investigation of a technique for sulfur reduction of mild gasification char. [Quarterly] report, December 1, 1991--February 29, 1992  

DOE Green Energy (OSTI)

The object of this program is to investigate the desulfurization of mild gasification char using H{sub 2}CH{sub 4} mixtures in a laboratory-scale experimental study. Mild gasification is a coal conversion technique which produces solid, liquid, and gaseous co-products. Char is the major co-product, about 60% of the dry coal yield. Form coke for steelmaking and foundries presents the best potential high-value markets for chars from eastern bituminous coals. Conventional metallurgical cokes generally contain about 1 wt% or less sulfur. Mild gasification char from high-sulfur Illinois coals must be upgraded to meet these criteria. One method to accomplish this is desulfurization with reducing gases derived from the mild gasification co-product gases. Because form coke has a market value up to $200/ton, it can accommodate desulfurization costs and still be economically attractive. The desulfurization can be performed either on the granular char or on formed-briquettes.

Upgrading mild gasification liquids to produce electrode binder pitch. Final technical report, 1 September, 1992--31 August, 1993  

Science Conference Proceedings (OSTI)

The objective of this program is to investigate the production of electrode binder pitch, from mild gasification liquids. The IGT MILDGAS process pyrolyzes coal in a fluidized/entrained bed to produce solid, gas, and liquid co-products. The largest market for pitch made from coal liquids is the aluminum industry, which uses it to make carbon anodes for electrolytic furnaces. In this project, crude pitch from the DOE-sponsored MILDGAS process research programs being modified by a flash thermocracking technique to achieve specifications typical of a binder pitch. Atomization of the pitch at the thermocracker inlet is being examined as a method of optimizing the particle size of polymerized pitch components. Six successful thermocracking tests were performed with a crude Illinois No. 6 pitch from 1,110 F MILDGAS PRU runs. The tests were conducted at 1,200--1,500 F with pitch feed rates of 2.6--12.7 g/min and residence times of 2.6--4.5 seconds. Tests were conducted with and without an atomizing nozzle to evaluate the effects of atomization on the primary quinoline- and toluene-insoluble (QI and TI) content of the pitch. Key pitch properties improved in all cases, with higher temperatures resulting in increased softening point (187--273 F), QI (10--16%), TI (18--41%), coking value (38--55%), C:H ratio (1.17--1.57), and density (1.16--1.26). Higher reactor loading appears to promote more coke and gas production, but atomization promotes higher yield of cracked pitch, oil, and gas and less coke. The products of pitch cracking ranged from 26--54 wt% cracked pitch, 13--44 wt% coke, 16--28 wt% oils, and 3--23 wt% high-Btu gas. The pitch cokes had C:H atomic ratios of 1.95--2.93, which could be increased by calcination for use as a carbon anode filler.

Toxicity studies of mild gasification products. Quarterly report, October--December 1993  

Science Conference Proceedings (OSTI)

The major hypothesis of carcinogenesis is that malignancy is due to an alteration (mutation) of the genetic material in a somatic cell. Reactive electrophilic metabolites are generated from many chemicals by the action of endogenous mixed-function oxidases. These reactive metabolites may bind to cellular macromolecules, such as DNA, and can, therefore, initiate a mutagenic or carcinogenic event. Prokaryotes and non-mammalian eukaryotes are used in mutation assays, while cultured mammalian cells are generally used for mutagenic as well as clastogenic tests examining alterations and damage to the DNA and/or chromosomes of somatic cells. One of the first mammalian cell lines used in genotoxicity studies is V79, which was derived from Chinese hamster lung cells. According to the test plan on toxicity studies of mild gasification products, mammalian cell in vitro assays are to be performed on selected samples displaying mutagenic activity in the Ames assay. The results of the Ames testing of the mild gasification sample Shell Oil PSIS{number_sign}330331 were negative. However, fractionation of the sample and Ames testing of the subfractions were performed per DOE request. None of the subfractions was mutagenic in the Ames assay, as has been previously reported. Assays for the induction of gene mutation, sister chromatid exchange and micronucleus formation in V79 cells have also been carried out for the sample. This paper reports the results of the mammalian cell assay.

Mild coal pretreatment to improve liquefaction reactivity. Quarterly technical progress report, June--August 1991  

SciTech Connect

This report describes work completed during the fourth quarter of a three year project to study the effects of mild chemical pretreatment on coal dissolution reactivity during low severity liquefaction or coal/oil coprocessing. The overall objective of this research is to elucidate changes in the chemical and physical structure of coal by pretreating with methanol or other simple organic solvent and a trace amount of hydrochloric acid and measure the influence of these changes on coal dissolution reactivity. This work is part of a larger effort to develop a new coal liquefaction or coal/oil coprocessing scheme consisting of three main process steps: (1) mile pretreatment of the feed coal to enhance dissolution reactivity and dry the coal, (2) low severity thermal dissolution of the pretreated coal to obtain a very reactive coal-derived residual material amenable to upgrading, and (3) catalytic upgrading of the residual products to distillate liquids.

Facilities engineering is one technical field where lab-based continuing education programs can be delivered in a distance learning format. The widespread use of computer controls for optimizing the efficiency of a building's mechanical and electrical systems has made the "distance" element possible. Rather than traveling to individual buildings to make pressure, temperature, and flow measurements in person, facility engineers routinely access performance data over the Internet. This networking capability has been used in an educational setting to deliver interactive technical training to large numbers of undergraduate students and professional facilities engineers. Many students can access real time data from a single piece of HVAC equipment over the Internet.

Alpha-environmental continuous air monitor inlet  

DOE Patents (OSTI)

A wind deceleration and protective shroud that provides representative samples of ambient aerosols to an environmental continuous air monitor (ECAM) has a cylindrical enclosure mounted to an input on the continuous air monitor, the cylindrical enclosure having shrouded nozzles located radially about its periphery. Ambient air flows, often along with rainwater flows into the nozzles in a sampling flow generated by a pump in the continuous air monitor. The sampling flow of air creates a cyclonic flow in the enclosure that flows up through the cylindrical enclosure until the flow of air reaches the top of the cylindrical enclosure and then is directed downward to the continuous air monitor. A sloped platform located inside the cylindrical enclosure supports the nozzles and causes any moisture entering through the nozzle to drain out through the nozzles.

Characterizing and modeling combustion of mild-gasification chars in pressurized fluidized beds  

Science Conference Proceedings (OSTI)

Performance estimates for the UCC2, IGTP1, and IGTP2 chars were made for a typical utility PFBC boiler having nominal characteristics similar to those of the American Electric Power 75 MW(e) Tidd PFBC demonstration facility. Table 2 summarizes the assumed boiler operating conditions input to the PFBC simulation code. Input fuel parameters for the chars and reference fuels were determined from their standard ASTM analyses (Table 1) and the results of the bench-scale characterization tests at B&W`s Alliance Research Center. The required characterization information for the reference fuels was available from the B&W data base, and the combustion reactivity information for the mild-gasification chars was generated in the pressurized bench-scale reactor as described earlier. Note that the combustion reactivity parameters for Beulah lignite are those previously measured at low-pressure conditions. It was necessary to use the previous values as the new parameters could not be accurately measured in the pressurized bench-scale facility. Based on very limited measurements of particle size attrition in paste-type feed systems, it was assumed that all of the fuels (including the chars) would have a very small (essentially negligible) degree of attrition in the feed system. Char devolatilization parameters were assumed to be equal to those of anthracite because of the very low levels of volatiles present in UCC2, IGTP1, and IGTP2. Major fuel input parameters and higher heating values are summarized in Table 3.

Low-Cost Solar Domestic Hot Water Systems for Mild Climates  

DOE Green Energy (OSTI)

In FY99, Solar Heating and Lighting set the goal to reduce the life-cycle cost of saved-energy for solar domestic hot water (SDHW) systems in mild climates by 50%, primarily through use of polymer technology. Two industry teams (Davis Energy Group/SunEarth (DEG/SE) and FAFCO) have been developing un-pressurized integral-collector-storage (ICS) systems having load-side heat exchangers, and began field-testing in FY04. DEG/SE?s ICS has a rotomolded tank and thermoformed glazing. Based upon manufacturing issues, costs, and poor performance, the FAFCO team changed direction in late FY04 from an un-pressurized ICS to a direct thermosiphon design based upon use of pool collectors. Support for the teams is being provided for materials testing, modeling, and system testing. New ICS system models have been produced to model the new systems. A new ICS rating procedure for the ICS systems is undergoing testing and validation. Pipe freezing, freeze protection valves, and overheating have been tested and analyzed.

Action principle for continuous quantum measurement  

E-Print Network (OSTI)

We present a stochastic path integral formalism for continuous quantum measurement that enables the analysis of rare events using action methods. By doubling the quantum state space to a canonical phase space, we can write the joint probability density function of measurement outcomes and quantum state trajectories as a phase space path integral. Extremizing this action produces the most-likely paths with boundary conditions defined by preselected and postselected states as solutions to a set of ordinary differential equations. As an application, we analyze continuous qubit measurement in detail and examine the structure of a quantum jump in the Zeno measurement regime.

Investigation of a sulfur reduction technique for mild gasification char. [Quarterly] technical report, March 1--May 31, 1993  

DOE Green Energy (OSTI)

The objective of this program is to investigate the desulfurization of mild gasification char using H{sub 2}:CH{sub 4} mixtures. Mild gasification of coal produces char, liquids, and gases at 1000{degrees}--1500{degrees}F and near-ambient pressure. Char, comprising 60--70% of the product, can be used to make high-value form coke for steel making and foundries. However, a sulfur content below 1 wt% is desirable, and char from high-sulfur Illinois coals must be upgraded to meet this criterion. Illinois No. 6 chars were treated in a batch fluidized bed with H{sub 2}:CH{sub 4} blends containing 9--24 vol% CH{sub 4} at 1100{degrees}--1600{degrees}F and 50--200 psig. Sulfur removal up to 92.5 wt% were obtainer, and the char desulfurization susceptibility was related to porosity, density, and crystallite size. The relationships among mild gasification parameters, char properties, and char desulfurization susceptibility are being studied. Acid washing of coal to remove Ca and Fe is being explored for its effect on subsequent sulfur removal, and secondary desulfurization of form coke produced from the desulfurized chars is also being studied. Desulfurization tests of entrained and fluidized-bed reactor chars from IBC-105 coal (4.1--4.3 wt% sulfur) were completed. Desulfurization conditions were 1400{degrees}F, 100--200 psig and reactant gas compositions of 15-49 vol% CH{sub 4} in H{sub 2}. Sulfur removal ranged from 28 to 95%, with carbon losses from 5 to 29%. Acid-washing of the coal prior to mild gasification or the char prior to desulfurization increased its susceptibility to desulfurization, with sulfur content reduced to as low as 0.10 wt% dry char. Fluidized-bed chars were easier to desulfurize than entrained chars, and were less affected by acid-washing.

A fast algorithm for Antoine and Vandergheynst's (1998) directional continuous spherical wavelet transform (CSWT) is presented. Computational requirements are reduced by a factor of O(\\sqrt{N}), when N is the number of pixels on the sphere. The spherical Mexican hat wavelet Gaussianity analysis of the WMAP 1-year data performed by Vielva et al. (2003) is reproduced and confirmed using the fast CSWT. The proposed extension to directional analysis is inherently afforded by the fast CSWT algorithm.

Continuous Circulation System: a new enabling technology  

E-Print Network (OSTI)

Wellbore problems have existed since the very first oil well was drilled. These problems have cost the oil industry millions of dollars because they lead to substantial loss of valuable rig time, or even loss of the well. Some of these problems are caused by the interruption of the drilling-fluid circulation. This interruption normally occurs when making drillpipe connections. Interruption of circulation causes wellbore problems like ballooning of the well, gelation of drilling mud, and settling of drilled cuttings. It also causes some operating problems in underbalanced drilling. A new technology in drilling has been introduced through a joint industry project to overcome problems caused by interruption of circulation. This technology is the Continuous Circulation System (CCS). The CCS is capable of achieving continuous circulation while making/breaking drillpipe connections. This research highlights the significance of the new technology by investigating the problems caused by interruption of circulation. It presents some potential operational problems regarding the new system and discusses the possibility to achieve continuous drilling. The economics of the new technology is presented. This study found that the CCS would prevent significant wellbore problems from occurring, hence saving valuable rig time and money. It also showed that CCS would be a valuable addition to the equipment used in underbalanced drilling. Continuous drilling while making connections can be achieved using mud-motors. On the other hand, it is not feasible through rotation of the drillstring under the current technology. Finally, the suitable marketing strategy for this phase of the new technology is to offer it for lease rather than for sale.

Continuous-time quantum error correction  

E-Print Network (OSTI)

Continuous-time quantum error correction (CTQEC) is an approach to protecting quantum information from noise in which both the noise and the error correcting operations are treated as processes that are continuous in time. This chapter investigates CTQEC based on continuous weak measurements and feedback from the point of view of the subsystem principle, which states that protected quantum information is contained in a subsystem of the Hilbert space. We study how to approach the problem of constructing CTQEC protocols by looking at the evolution of the state of the system in an encoded basis in which the subsystem containing the protected information is explicit. This point of view allows us to reduce the problem to that of protecting a known state, and to design CTQEC procedures from protocols for the protection of a single qubit. We show how previously studied CTQEC schemes with both direct and indirect feedback can be obtained from strategies for the protection of a single qubit via weak measurements and weak unitary operations. We also review results on the performance of CTQEC with direct feedback in cases of Markovian and non-Markovian decoherence, where we have shown that due to the existence of a Zeno regime in non-Markovian dynamics, the performance of CTQEC can exhibit a quadratic improvement if the time resolution of the weak error-correcting operations is high enough to reveal the non-Markovian character of the noise process.

Establishing a rodent (Fischer 344 rat) model of mild cognitive impairment in aging  

E-Print Network (OSTI)

Mild Cognitive Impairment is characterized by age-related decline in a variety of cognitive domains, including reference and working memory and olfactory function. Importantly, declining age-related mnemonic abilities is not inevitable; learning and memory deficits emerge in some people by middle-age while others remain largely cognitively-intact even at advanced chronological ages. The goal of this thesis is to establish a Fischer 344 (F344) rat model with some features of human cognitive aging which can then be utilized to undercover the neurobiological underpinnings of age-related cognitive deficits. Young (6 mo), middle-aged (11 mo), and aged (22 mo) F344 rats were behaviorally characterized in a well-established reference memory version of the Morris water maze task. Indeed, age-related impairments did occur across the lifespan. Moreover, the reference memory protocol used here was sufficiently sensitive to detect a difference in individual abilities among aged F344 rats such that approximately half of the rats performed on par with young while the other half performed outside this range, demonstrating impairment. These data mimic individual differences in declarative memory among aged humans. Subsequently, subsets of rats initially characterized on the reference memory version of the water maze were tested on either a spatial working memory water maze task or an olfactory discrimination task. Despite detecting an age-related delay-dependent decline in spatial working memory, this impairment was not correlated with spatial reference memory. In contrast, a strong and significant relationship was observed among aged rats in the odor discrimination task such that aged rats with the worst spatial reference memory were also the most impaired in their ability to discriminate odors for a food reward. Importantly, this subset of cognitively-impaired rats was not impaired on digging media discrimination problems with identical task demands, nor were they anosmic. These data are among the first to demonstrate a cross-domain cognitive deficit in a rodent model of human aging. Together, the current study both confirms the use of the naturalistic F344 rat model for the study of cognitive deficits within the context of aging and provides the most comprehensive cognitive profile of this rat population to date.

High-temperature helium-loop facility  

Science Conference Proceedings (OSTI)

The high-temperature helium loop is a facility for materials testing in ultrapure helium gas at high temperatures. The closed loop system is capable of recirculating high-purity helium or helium with controlled impurities. The gas loop maximum operating conditions are as follows: 300 psi pressure, 500 lb/h flow rate, and 2100/sup 0/F temperature. The two test sections can accept samples up to 3.5 in. diameter and 5 ft long. The gas loop is fully instrumented to continuously monitor all parameters of loop operation as well as helium impurities. The loop is fully automated to operate continuously and requires only a daily servicing by a qualified operator to replenish recorder charts and helium makeup gas. Because of its versatility and high degree of parameter control, the helium loop is applicable to many types of materials research. This report describes the test apparatus, operating parameters, peripheral systems, and instrumentation system.

Dynamical paths and universality in continuous variables open systems  

E-Print Network (OSTI)

We address the dynamics of quantum correlations in continuous variable open systems and analyze the evolution of bipartite Gaussian states in independent noisy channels. In particular, upon introducing the notion of dynamical path through a suitable parametrization for symmetric states, we focus attention on phenomena that are common to Markovian and non-Markovian Gaussian maps under the assumptions of weak coupling and secular approximation. We found that the dynamical paths in the parameter space are universal, that is they do depend only on the initial state and on the effective temperature of the environment, with non Markovianity that manifests itself in the velocity of running over a given path. This phenomenon allows one to map non-Markovian processes onto Markovian ones and it may reduce the number of parameters needed to study a dynamical process, e.g. it may be exploited to build constants of motions valid for both Markovian and non-Markovian maps. Universality is also observed in the value of Gaussian discord at the separability threshold, which itself is a function of the sole initial conditions in the limit of high temperature. We also prove the existence of excluded regions in the parameter space, i.e. of sets of states which cannot be linked by any Gaussian dynamical map.

E-Print Network (OSTI)

The quantum noise is calculated based on the description of imprecise measurement theory, which is used to analyse the general detector's quantum limit in continuous quantum measurement. Different from the traditional description of the linear-response theory, we don't introduce the hypotheses on the properties of the susceptibilities of the detector, and first show a rigorous result: The minimum noise added by the detector in quantum measurement is precisely equal to the zero-point noise. We also discuss the statistic characters of the back-action force in quantum measurement and show how to reach the quantum limit.

Distillation by repeated measurements: Continuous spectrum case  

Science Conference Proceedings (OSTI)

Repeated measurements on one part of a bipartite system strongly affect the other part that is not measured, the dynamics of which is regulated by an effective contracted evolution operator. When the spectrum of this operator is discrete, the nonmeasured system is driven into a pure state, irrespective of the initial state, provided that the spectrum satisfies certain conditions. We show here that, even in the case of continuous spectrum, an effective distillation can occur under rather general conditions. We confirm it by applying our formalism to a simple model.

Investigation of a sulfur reduction technique for mild gasification char. Technical report, December 1, 1992--February 28, 1993  

DOE Green Energy (OSTI)

The objective of this program is to investigate the desulfurization of mild gasification char using H{sub 2}:CH{sub 4} mixtures. Mild gasification of coal produces char, liquids, and gases at 1000{degrees}--1500{degrees}F (538{degrees}-816{degrees}C) and near-ambient pressure. Char, comprising 60--70% of the product, can be used to make high-value form coke for steelmaking and foundries. However, a sulfur content below 1 wt% is desirable, and char from high-sulfur Illinois coals must be upgraded to meet this criterion. Illinois No. 6 chars were treated in a 2-inch batch fluidized-bed reactor with H{sub 2}:CH{sub 4} blends containing 9--24 vol % CH{sub 4} at 1100{degrees}-1600{degrees}F (538{degrees}-871{degrees}C) and 50--200 psig (0.35--1.38 Mpa). The data from these tests show sulfur removal of 6.0--92.5 wt % and carbon losses of 0.0--25.6 wt %, with the desulfurization susceptibility of char related to porosity, density, and crystallite size. The relationships among mild gasification parameters, char properties, and char desulfurization susceptibility are being studied. Acid washing of char to remove Ca and Fe is being explored for its effect on subsequent sulfur removal. Secondary desulfurization of form coke produced from the desulfurized chars is also being studied, and a final recommendation will be made for integration of char desulfurization into the IGT MILDGAS process.

D81(2010)125003 for the scalar $\\phi^4$ theory, consists in substitution of the local fields $\\phi(x)$ by those dependent on both the position $x$ and the resolution $a$. The substitution of the action $S[\\phi(x)]$ by the action $S[\\phi_a(x)]$ makes the local theory into nonlocal one, and implies the causality conditions related to the scale $a$, the region causality C. Christensen and L. Crane, J.Math. Phys 46 (2005) 122502. These conditions make the Green functions $G(x_1,a_1,..., x_n,a_n)= $ finite for any given set of regions by means of an effective cutoff scale $A=\\min (a_1,...,a_n)$.

Widespread penetration of renewable energy and increasing demands on reliability/security of the electrical grid require extensive advances in Widespread penetration of renewable energy and increasing demands on reliability/security of the electrical grid require extensive advances in energy storage technologies that are modular and scalable (kW-MW). Among the most promising technologies is the sodium-beta battery (NBB) based on Na+ conducting beta-alumina (ȕƎ-Al2O3) electrolytes and operated at elevated temperatures (300-350oC). These batteries have demonstrated round-trip efficiencies >90%, storage capacity up to MWhs for hours of duration, and millisecond response times. However, current (NBB), constructed with 1-3 millimeter thick, tubular, electrolytes, have high capital cost, performance/safety issues, and high temperature operation (300-350°C) that limit widespread adoption of this technology into the market. Here we propose to develop and demonstrate a modular

Cooled, temperature controlled electrometer  

DOE Patents (OSTI)

A cooled, temperature controlled electrometer for the measurement of small currents. The device employs a thermal transfer system to remove heat from the electrometer circuit and its environment and dissipate it to the external environment by means of a heat sink. The operation of the thermal transfer system is governed by a temperature regulation circuit which activates the thermal transfer system when the temperature of the electrometer circuit and its environment exceeds a level previously inputted to the external variable temperature control circuit. The variable temperature control circuit functions as subpart of the temperature control circuit. To provide temperature stability and uniformity, the electrometer circuit is enclosed by an insulated housing.

Range Selectivity Estimation for Continuous Attributes  

E-Print Network (OSTI)

Many commercial database systems maintain histograms to efficiently estimate query selectivities as part of query optimization. Most work on histogram design is implicitly geared towards discrete or categorical attribute value domains. In this paper, we consider approaches that are better suited for the continuous valued attributes commonly found in scientific and statistical databases. We propose two methods based on spline functions for estimating the selectivity of range queries over univariate and multivariate data. These methods are more accurate than histograms. As the results from our experiments on both real and synthetic data sets demonstrate, the proposed methods achieved substantially better (up to 5.5 times) estimation error than the state-of-the-art histograms, at exactly the same storage space and with comparable CPU runtime overhead; moreover, the superiority of the proposed spline methods is amplified when applied to multivariate data. 1 Introduction Selectivity esti...

Quantifying decoherence in continuous variable systems  

E-Print Network (OSTI)

We present a detailed report on the decoherence of quantum states of continuous variable systems under the action of a quantum optical master equation resulting from the interaction with general Gaussian uncorrelated environments. The rate of decoherence is quantified by relating it to the decay rates of various, complementary measures of the quantum nature of a state, such as the purity, some nonclassicality indicators in phase space and, for two-mode states, entanglement measures and total correlations between the modes. Different sets of physically relevant initial configurations are considered, including one- and two-mode Gaussian states, number states, and coherent superpositions. Our analysis shows that, generally, the use of initially squeezed configurations does not help to preserve the coherence of Gaussian states, whereas it can be effective in protecting coherent superpositions of both number states and Gaussian wave packets. 1

DOE Patents (OSTI)

A blood separation centrifuge rotor having a generally parabolic core disposed concentrically and spaced apart within a housing having a similarly shaped cavity. Blood is introduced through a central inlet and into a central passageway enlarged downwardly to decrease the velocity of the entrant blood. Septa are disposed inside the central passageway to induce rotation of the entrant blood. A separation chamber is defined between the core and the housing wherein the whole blood is separated into red cell, white cell, and plasma zones. The zones are separated by annular splitter blades disposed within the separation chamber. The separated components are continuously removed through conduits communicating through a face seal to the outside of the rotor.

Continuous Emission of A Radiation Quantum  

E-Print Network (OSTI)

It is in accordance with such experiments as single photon self-interference that a photon, conveying one radiation energy quantum "$ h \\times$ frequency", is spatially extensive and stretches an electromagnetic wave train. A wave train, hence an energy quantum, can only be emitted by its source gradually. In both the two processes the wave and "particle" attributes of the radiation field are simultaneously prominent, where an overall satisfactory theory has been lacking. This paper presents a first principles treatment, in a unified framework of the classical and quantum mechanics, of the latter process, the emission of a single radiation quantum based on the dynamics of the radiation-emitting source, a charged oscillator which is itself extensive across its confining potential well. During the emission of one single radiation quantum, the extensive charged oscillator undergoes a continuous radiation damping and is non-stationary. This process is in this work treated using a quasi stationary approach, whereby the classical equation of motion, which directly facilitates the correspondence principle for a particle oscillator, and the quantum wave equation are established for each sufficiently brief time interval. As an inevitable consequence of the division of the total time for emitting one single quantum, a fractional Planck constant $h$ is introduced. The solutions to the two simultaneous equations yield for the charged oscillator a continuously exponentially decaying Hamiltonian that is at the same time quantised with respect to the fractional-$h$ at any instant of time; and the radiation wave field emitted over time stretches a wave train of finite length. The total system of the source and radiation field maintains at any time (integer $n$ times) one whole energy quantum, $h \\times$ frequency, in complete accordance with the notion of quantum mechanics and experiment.

DEVELOPMENT OF CONTINUOUS SOLVENT EXTRACTION PROCESSES FOR COAL DERIVED CARBON PRODUCTS  

Science Conference Proceedings (OSTI)

The purpose of this DOE-funded effort is to develop continuous processes for solvent extraction of coal for the production of carbon products. These carbon products include materials used in metals smelting, especially in the aluminum and steel industries, as well as porous carbon structural material referred to as ''carbon foam'' and carbon fibers. A process has been developed which results in high quality binder pitch suitable for use in graphite electrodes or carbon anodes. A detailed description of the protocol is given by Clendenin. Briefly, aromatic heavy oils are hydro-treated under mild conditions in order to increase their ability to dissolve coal. An example of an aromatic heavy oil is Koppers Carbon Black Base (CBB) oil. CBB oil has been found to be an effective solvent and acceptably low cost (i.e., significantly below the market price for binder pitch, or about $280 per ton at the time of this writing). It is also possible to use solvents derived from hydrotreated coal and avoid reliance on coke oven recovery products completely if so desired.

Continuous variable tangle, monogamy inequality, and entanglement sharing in Gaussian states of continuous variable systems  

E-Print Network (OSTI)

For continuous-variable systems, we introduce a measure of entanglement, the continuous variable tangle ({\\em contangle}), with the purpose of quantifying the distributed (shared) entanglement in multimode, multipartite Gaussian states. This is achieved by a proper convex roof extension of the squared logarithmic negativity. We prove that the contangle satisfies the Coffman-Kundu-Wootters monogamy inequality in all three--mode Gaussian states, and in all fully symmetric $N$--mode Gaussian states, for arbitrary $N$. For three--mode pure states we prove that the residual entanglement is a genuine tripartite entanglement monotone under Gaussian local operations and classical communication. We show that pure, symmetric three--mode Gaussian states allow a promiscuous entanglement sharing, having both maximum tripartite residual entanglement and maximum couplewise entanglement between any pair of modes. These states are thus simultaneous continuous-variable analogs of both the GHZ and the $W$ states of three qubits: in continuous-variable systems monogamy does not prevent promiscuity, and the inequivalence between different classes of maximally entangled states, holding for systems of three or more qubits, is removed.

Black hole solutions are shown to exist for a phantom scalar field whose kinetic energy is negative. These ``scalar black holes'' have an infinite horizon area and zero Hawking temperature and are termed ``cold black holes'' (CBHs). The relevant explicit solutions are well-known in the massless case (the so-called anti-Fisher solution), and we have found a particular example of a CBH with a nonzero potential $V(\\phi)$.

Continuous Time Group Discovery in Dynamic Graphs  

Science Conference Proceedings (OSTI)

With the rise in availability and importance of graphs and networks, it has become increasingly important to have good models to describe their behavior. While much work has focused on modeling static graphs, we focus on group discovery in dynamic graphs. We adapt a dynamic extension of Latent Dirichlet Allocation to this task and demonstrate good performance on two datasets. Modeling relational data has become increasingly important in recent years. Much work has focused on static graphs - that is fixed graphs at a single point in time. Here we focus on the problem of modeling dynamic (i.e. time-evolving) graphs. We propose a scalable Bayesian approach for community discovery in dynamic graphs. Our approach is based on extensions of Latent Dirichlet Allocation (LDA). LDA is a latent variable model for topic modeling in text corpora. It was extended to deal with topic changes in discrete time and later in continuous time. These models were referred to as the discrete Dynamic Topic Model (dDTM) and the continuous Dynamic Topic Model (cDTM), respectively. When adapting these models to graphs, we take our inspiration from LDA-G and SSN-LDA, applications of LDA to static graphs that have been shown to effectively factor out community structure to explain link patterns in graphs. In this paper, we demonstrate how to adapt and apply the cDTM to the task of finding communities in dynamic networks. We use link prediction to measure the quality of the discovered community structure and apply it to two different relational datasets - DBLP author-keyword and CAIDA autonomous systems relationships. We also discuss a parallel implementation of this approach using Hadoop. In Section 2, we review LDA and LDA-G. In Section 3, we review the cDTM and introduce cDTMG, its adaptation to modeling dynamic graphs. We discuss inference for the cDTM-G and details of our parallel implementation in Section 4 and present its performance on two datasets in Section 5 before concluding in Section 6.

The organic solvent or solvents are chosen so as to melt at a specific temperature or in a specific temperature range. When the temperature of the indicator is elevated above the chosen, or critical temperature, the solid organic solvent support will melt, and the enzymatic reaction will occur, producing a visually detectable product which is stable to further temperature variation.

Continuous Air Monitor Operating Experience Review  

Science Conference Proceedings (OSTI)

Continuous air monitors (CAMs) are used to sense radioactive particulates in room air of nuclear facilities. CAMs alert personnel of potential inhalation exposures to radionuclides and can also actuate room ventilation isolation for public and environmental protection. This paper presents the results of a CAM operating experience review of the DOE Occurrence Reporting and Processing System (ORPS) database from the past 18 years. Regulations regarding these monitors are briefly reviewed. CAM location selection and operation are briefly discussed. Operating experiences reported by the U.S. Department of Energy and in other literature sources were reviewed to determine the strengths and weaknesses of these monitors. Power losses, human errors, and mechanical issues cause the majority of failures. The average all modes failure rate is 2.65E-05/hr. Repair time estimates vary from an average repair time of 9 hours (with spare parts on hand) to 252 hours (without spare parts on hand). These data should support the use of CAMs in any nuclear facility, including the National Ignition Facility and the international ITER experiment.

Continuous chain bit with downhole cycling capability  

DOE Patents (OSTI)

A continuous chain bit for hard rock drilling is disclosed which is capable of downhole cycling. A drill head assembly moves axially relative to a support body while the chain on the head assembly is held in position so that the bodily movement of the chain cycles the chain to present new composite links for drilling. A pair of spring fingers on opposite sides of the chain hold the chain against movement. The chain is held in tension by a spring-biased tensioning bar. A head at the working end of the chain supports the working links. The chain is centered by a reversing pawl and piston actuated by the pressure of the drilling mud. Detent pins lock the head assembly with respect to the support body and are also operated by the drilling mud pressure. A restricted nozzle with a divergent outlet sprays drilling mud into the cavity to remove debris. Indication of the centered position of the chain is provided by noting a low pressure reading indicating proper alignment of drilling mud slots on the links with the corresponding feed branches.

Yeast and Temperature Yeast and Temperature Name: Alyssaaum Location: N/A Country: N/A Date: N/A Question: How does temperature affect yeast? Replies: Dear Alyssa, At low temperatures (0-10 C) yeast will not grow, but not die either. At temperatures 10-37 C yeast will grow and multiply, faster at higher temperatures with an optimal growth at 30 or 37 C (that depends on the species). At higher temperature the cells become stressed, meaning that their content becomes damaged and which can be repaired to some degree. At high temperatures (>50 C) the cells die.

High coefficient of performance thermoelectrics with a figure of merit (ZT) exceeding 1, can potentially harness approximately 4.3% of this waste heat and add 23% to the current electricity production at zero additional carbon or noise emission. Inspired by the preliminary demonstration of silicon nanowires with ZT of 0.6 at room temperature, we propose using an economic and highly scalable non-lithographic approach to fabricate size-controllable, waferscale arrays of rough-surface, one-dimensional concentric nanotubes of silicon to increase surface scattering, followed by transfer printing to manufacture flexible thermoelectric junctions.

RTDS: A continuous, rapid, thermal synthesis mode  

SciTech Connect

The Rapid Thermal Decomposition of precursors in Solution (RTDS) Process is a flow-through hydrothermal powder synthesis method capable of producing nanophase oxide and oxyhydroxide catalysts and catalyst precursors. The RTDS technique utilizes a brief exposure of dissolved precursors to high pressure/high temperature aqueous conditions to initiate crystallite nucleation. The resulting nanocrystalline suspension is removed from the hydrothermal environment through a pressure let-down device before significant crystallite growth can occur. The RTDS process is discussed as a method to produce nanocrystalline iron oxide and oxyhydroxide powders that exhibit high activity as carbon-carbon bond cleavage catalyst precursors. Nanocrystalline TiO{sub 2} and ZrO{sub 2} powders having prospective catalytic applications are also produced by the RTDS process.

Development of high energy density fuels from mild gasification of coal. Final report  

SciTech Connect

METC has concluded that MCG technology has the potential to simultaneously satisfy the transportation and power generation fuel needs in the most cost-effective manner. MCG is based on low temperature pyrolysis, a technique known to the coal community for over a century. Most past pyrolysis developments were aimed at maximizing the liquids yield which results in a low quality tarry product requiring significant and capital intensive upgrading. By properly tailoring the pyrolysis severity to control the liquid yield-liquid quality relationship, it has been found that a higher quality distillate-boiling liquid can be readily ``skimmed`` from the coal. The resultant liquids have a much higher H/C ratio than conventional pyrolytic tars and therefore can be hydroprocessed at lower cost. These liquids are also extremely enriched in l-, 2-, and 3-ring aromatics. The co-product char material can be used in place of coal as a pulverized fuel (pf) for power generation in a coal combustor. In this situation where the original coal has a high sulfur content, the MCG process can be practiced with a coal-lime mixture and the calcium values retained on the char can tie up the unconverted coal sulfur upon pf combustion of the char. Lime has also been shown to improve the yield and quality of the MCG liquids.

Synergetic effects of double laser pulses for the formation of mild plasma in water: Toward non-gated underwater laser-induced breakdown spectroscopy  

Science Conference Proceedings (OSTI)

We experimentally study the dynamics of the plasma induced by the double-laser-pulse irradiation of solid target in water, and find that an appropriate choice of the pulse energies and pulse interval results in the production of an unprecedentedly mild (low-density) plasma, the emission spectra of which are very narrow even without the time-gated detection. The optimum pulse interval and pulse energies are 15-30 {mu}s and about {approx}1 mJ, respectively, where the latter values are much smaller than those typically employed for this kind of study. In order to clarify the mechanism for the formation of mild plasma we examine the role of the first and second laser pulses, and find that the first pulse produces the cavitation bubble without emission (and hence plasma), and the second pulse induces the mild plasma in the cavitation bubble. These findings may present a new phase of underwater laser-induced breakdown spectroscopy.

Synthesis of graphene-based Pt nanoparticles by a one-step in situ plasma approach under mild conditions  

Science Conference Proceedings (OSTI)

Herein, a one-step in situ plasma approach to synthesize the highly dispersed Pt nanoparticles on graphene under mild conditions is reported. The graphene oxide (GO) was transformed into graphene and H{sub 2}PtCl{sub 6} was simultaneously transformed into Pt nanoparticles under argon plasma conditions. The synthesized graphene-based Pt nanoparticles were characterized by scanning electron microscopy, atomic force microscopy, x-ray diffraction, and Fourier transform infrared spectroscopy. The analysis showed that the Pt nanoparticles were deposited on graphene as a form of face-centered cubical structure and the oxygen groups on graphene oxide were partially removed. The results of x-ray photoelectron spectroscopy analysis further confirmed the results.

Review of corrosion in 10- and 14-ton mild steel depleted UF{sub 6} storage cylinders  

Science Conference Proceedings (OSTI)

A literature review was conducted to determine the type, extent and severity of corrosion found in the 10- and 14-ton mild steel depleted UF{sub 6} storage cylinders. Also discussed in this review is corrosion found in the valves and plugs used in the cylinders. Corrosion of the cylinders is a gradual process which occurs slowly over time. Understanding corrosion of the cylinders is an important concern for long term storage of the UF{sub 6} in the cylinder yards, as well as the final disposition of the depleted UF{sub 6} tails inventory in the future. The following conclusions are made from the literature review: (1) The general external corrosion rate of the cylinders is about 1 to 2 mils per year (1 mil = 0.001{double_prime}). The highest general external corrosion rate was over 5 mpy on the 48G type cylinders. (2) General internal corrosion from the depleted UF{sub 6} is negligible under normal storage conditions. Crevice corrosion can occur at the cylinder/saddle interface from the retention of water in this area. Crevice corrosion can occur at the cylinder/skirt interface on the older skirted cylinders due to the lack of water drainage in this area. Crevice corrosion can occur on cylinders that have been in ground contact. Crevice corrosion and galvanic corrosion can occur where the stainless steel I.D. nameplates are attached to the cylinder. The packing nuts on the bronze one-inch valves used in the cylinders are susceptible to stress corrosion cracking (SCC). Mechanical damage from routine handling can lead to a breach in a cylinder with subsequent accelerated corrosion of the mild steel due to attack from HF and other UF{sub 6} hydrolysis by-products.

Completing Pre-Pilot Tasks To Scale Up Biomass Fractionation Pretreatment Apparatus From Batch To Continuous  

DOE Green Energy (OSTI)

PureVision Technology, Inc. (PureVision) was the recipient of a $200,000 Invention and Innovations (I&I) grant from the U. S. Department of Energy (DOE) to complete prepilot tasks in order to scale up its patented biomass fractionation pretreatment apparatus from batch to continuous processing. The initial goal of the I&I program, as detailed in PureVision's original application to the DOE, was to develop the design criteria to build a small continuous biomass fractionation pilot apparatus utilizing a retrofitted extruder with a novel screw configuration to create multiple reaction zones, separated by dynamic plugs within the reaction chamber that support the continuous counter-flow of liquids and solids at elevated temperature and pressure. Although the ultimate results of this 27-month I&I program exceeded the initial expectations, some of the originally planned tasks were not completed due to a modification of direction in the program. PureVision achieved its primary milestone by establishing the design criteria for a continuous process development unit (PDU). In addition, PureVision was able to complete the procurement, assembly, and initiate shake down of the PDU at Western Research Institute (WRI) in Laramie, WY during August 2003 to February 2004. During the month of March 2004, PureVision and WRI performed initial testing of the continuous PDU at WRI.

The heart of the AOS CO2 Airborne Rack Mounted Analyzer System is the AOS Manifold. The AOS Manifold is a nickel coated aluminum analyzer and gas processor designed around two identical nickel-plated gas cells, one for reference gas and one for sample gas. The sample and reference cells are uniquely designed to provide optimal flushing efficiency. These cells are situated between a black-body radiation source and a photo-diode detection system. The AOS manifold also houses flow meters, pressure sensors and control valves. The exhaust from the analyzer flows into a buffer volume which allows for precise pressure control of the analyzer. The final piece of the analyzer is the demodulator board which is used to convert the DC signal generated by the analyzer into an AC response. The resulting output from the demodulator board is an averaged count of CO2 over a specified hertz cycle reported in volts and a corresponding temperature reading. The system computer is responsible for the input of commands and therefore works to control the unit functions such as flow rate, pressure, and valve control.The remainder of the system consists of compressors, reference gases, air drier, electrical cables, and the necessary connecting plumbing to provide a dry sample air stream and reference air streams to the AOS manifold.

Continuous Control in Buildings with Bond Graphs  

E-Print Network (OSTI)

Global warming caused by CO2 emissions as a result of energy consumption, shows its growing effects on the average temperatures worldwide. Office buildings are responsible for a major share of the 40% of the energy consumption of the built environment. We look at a way to minimize the environmental load of office buildings and at the same moment improve indoor air quality and comfort for the occupants of offices. Therefore the end-users behavior of building occupants needs to be taken into account. New design approaches are needed to implement the behavior of occupants of buildings. Improvement of the energy consumption is made possible by agent-based systems for energy management in buildings. Human-in-the-loop Technology: a technology to implement user behavior is developed. By starting from the human perspective and use available and new technology, the outcome was focused on the ability to provide improved individual comfort for the end user. As the end-users become more important within energy infrastructure of buildings, the focus is on the occupant and therefore a bottom-up design approach has been developed. In the final article an example on the level of workplace will be presented.

Catalyst dispersion and activity under conditions of temperature- staged liquefaction  

DOE Green Energy (OSTI)

The general objectives of this research are (1) to investigate the use of highly dispersed catalysts for the pretreatment of coal by mild hydrogenation, (2) to identify the active forms of the catalysts under reaction conditions and (3) to clarify the mechanisms of catalysis. The ultimate objective is to ascertain if mild catalytic hydrogenation resulting in very limited or no coal solubilization is an advantageous pretreatment for the transformation of coal into transportable fuels. The experimental program will focus upon the development of effective methods of impregnating coal with catalysts, evaluating the conditions under which the catalysts are most active and establishing the relative impact of improved impregnation on conversion and product distributions obtained from coal hydrogenation. Liquefaction experiments of solvent-treated and untreated Blind Canyon (DECS-6) and Texas lignite (DECS-1) have been performed using ammonium tetrathiomolybdate (ATTM) and bis (dicarbonylcyclopentadienyl) iron (CPI) as catalyst precursors using temperature-staged conditions (275{degrees}C, 30 min; 425{degrees}C, 30 min). Solid state {sup 13}C NMR analysis was carried out for each coal and for selected residues. 12 refs., 14 figs., 9 tabs.

APPLICATIONS OF CURRENT TECHNOLOGY FOR CONTINUOUS MONITORING OF SPENT FUEL  

Science Conference Proceedings (OSTI)

Advancements in technology have opened many opportunities to improve upon the current infrastructure surrounding the nuclear fuel cycle. Embedded devices, very small sensors, and wireless technology can be applied to Security, Safety, and Nonproliferation of Spent Nuclear Fuel. Security, separate of current video monitoring systems, can be improved by integrating current wireless technology with a variety of sensors including motion detection, altimeter, accelerometer, and a tagging system. By continually monitoring these sensors, thresholds can be set to sense deviations from nominal values. Then alarms or notifications can be activated as needed. Safety can be improved in several ways. First, human exposure to ionizing radiation can be reduced by using a wireless sensor package on each spent fuel cask to monitor radiation, temperature, humidity, etc. Since the sensor data is monitored remotely operator stay-time is decreased and distance from the spent fuel increased, so the overall radiation exposure is reduced as compared to visual inspections. The second improvement is the ability to monitor continuously rather than periodically. If changes occur to the material, alarm thresholds could be set and notifications made to provide advanced notice of negative data trends. These sensor packages could also record data to be used for scientific evaluation and studies to improve transportation and storage safety. Nonproliferation can be improved for spent fuel transportation and storage by designing an integrated tag that uses current infrastructure for reporting and in an event; tracking can be accomplished using the Iridium satellite system. This technology is similar to GPS but with higher signal strength and penetration power, but lower accuracy. A sensor package can integrate all or some of the above depending on the transportation and storage requirements and regulations. A sensor package can be developed using off the shelf technology and applying it to each specific need. There are products on the market for smart meters, industrial lighting control and home automation that can be applied to the Back End Fuel Cycle. With a little integration and innovation a cost effective solution is achievable.

High temperature refrigerator  

SciTech Connect

A high temperature magnetic refrigerator which uses a Stirling-like cycle in which rotating magnetic working material is heated in zero field and adiabatically magnetized, cooled in high field, then adiabatically demagnetized. During this cycle said working material is in heat exchange with a pumped fluid which absorbs heat from a low temperature heat source and deposits heat in a high temperature reservoir. The magnetic refrigeration cycle operates at an efficiency 70% of Carnot.

External vs. body temperature  

NLE Websites -- All DOE Office Websites (Extended Search)

External vs. body temperature External vs. body temperature Name: jacqui Location: N/A Country: N/A Date: N/A Question: If one's internal body temperature is approximately 98.6, WHY when the external temperature is 98.6 do we feel hot? Since both temperatures are "balanced", shouldn't we feel comfortable? I am assuming here that humidity levels are controlled, and play no factor in the external temperature. Replies: First of all, skin temperature is lower than 98.6F; 98.6F is internal body temperature, so air at 98.6F is hotter than skin. But more important, it is the nervous system, and the cells in your skin that your brain uses to detect temperature that determine whether you "feel" hot or not, not whether the air is hotter than your skin. These are set so that you feel hot when the air is actually colder than your skin. Why? They are probably set to make you feel hot whenever the air is warm enough so that your body has some trouble getting rid of the excess heat it produces through metabolism. This insures that you take some actions to help your body cool off. Like drinking cool water, or reducing exercise

Fiber optic temperature sensor  

SciTech Connect

Our fiber optic temperature measurement sensor and system is a major improvement over methods currently in use in most industrial processes, and it delivers all of the attributes required simplicity, accuracy, and cost efficiency-to help improve all of these processes. Because temperature is a basic physical attribute of nearly every industrial and commercial process, our system can eventually result in significant improvements in nearly every industrial and commercial process. Many finished goods, and the materials that go into them, are critically dependent on the temperature. The better the temperature measurement, the better quality the goods will be and the more economically they can be produced. The production and transmission of energy requires the monitoring of temperature in motors, circuit breakers, power generating plants, and transmission line equipment. The more reliable and robust the methods for measuring these temperature, the more available, stable, and affordable the supply of energy will become. The world is increasingly realizing the threats to health and safety of toxic or otherwise undesirable by products of the industrial economy in the environment. Cleanup of such contamination often depends on techniques that require the constant monitoring of temperature in extremely hazardous environments, which can damage most conventional temperature sensors and which are dangerous for operating personnel. Our system makes such monitoring safer and more economical.

Influence of microstructure on stress corrosion cracking of mild steel in synthetic caustic-nitrate nuclear waste solution  

DOE Green Energy (OSTI)

The influence of alloy microstructure on stress corrosion cracking of mild steel in caustic-nitrate synthetic nuclear waste solutions was studied. An evaluation was made of the effect of heat treatment on a representative material (ASTM A 516 Grade 70) used in the construction of high activity radioactive waste storage tanks at Savannah River Plant. Several different microstructures were tested for susceptibility to stress corrosion cracking. Precracked fracture specimens loaded in either constant load or constant crack opening displacement were exposed to a variety of caustic-nitrate and nitrate solutions. Results were correlated with the mechanical and corrosion properties of the microstructures. Crack velocity and crack arrest stress intensity were found to be related to the yield strength of the steel microstructures. Fractographic evidence indicated pH depletion and corrosive crack tip chemistry conditions even in highly caustic solutions. Experimental results were compatible with crack growth by a strain- assisted anodic dissolution mechanism; however, hydrogen embrittlement also was considered possible. (auth)

Design of a continuous-flow reactor for in situ x-ray absorption spectroscopy of solids in supercritical fluids  

Science Conference Proceedings (OSTI)

This paper presents the design and performance of a novel high-temperature and high-pressure continuous-flow reactor, which allows for x-ray absorption spectroscopy or diffraction in supercritical water and other fluids under high pressure and temperature. The in situ cell consists of a tube of sintered, polycrystalline aluminum nitride, which is tolerant to corrosive chemical media, and was designed to be stable at temperatures up to 500 deg. C and pressures up to 30 MPa. The performance of the reactor is demonstrated by the measurement of extended x-ray absorption fine structure spectra of a carbon-supported ruthenium catalyst during the continuous hydrothermal gasification of ethanol in supercritical water at 400 deg. C and 24 MPa.

Fever and Body Temperature  

NLE Websites -- All DOE Office Websites (Extended Search)

Fever and Body Temperature Fever and Body Temperature Name: Ying Location: N/A Country: N/A Date: N/A Question: Hi, I have a few questions that I want to ask you: Why does your body chose to raise its temperature when you have a fever? Replies: Most bacteria and viruses that live in your body grow best at body temperature. They don't grow very well when the temperature is raised. When there are bacteria in your body they give off chemicals that signal white blood cells to come to try to eat them and also affect an area in your brain called the hypothalamus. This part of the brain controls alot of the automatic functions in your body and is also the site of your body's "thermostat". When the chemicals from the bacteria circulate through the hypothalamus it sets the body's temperature higher. This is called a fever. Your body kind of tries to "sweat out" the bacteria and kill them with a higher temperature. Some scientists question whether trying to bring down a fever is the best thing to do. If it isn't too high, some believe we should just let it work

Maintaining body temperature  

NLE Websites -- All DOE Office Websites (Extended Search)

Maintaining body temperature Maintaining body temperature Name: Jeff Location: N/A Country: N/A Date: N/A Question: What keeps the human body at a constant temperature of 98.6? Replies: Maintaining body temperature is very complex. It also takes a lot of energy. About 80% of the energy from the food you eat goes to maintaining body temperature. Basically, the chemical reactions of metabolism of stored food, especially fats, generate heat as a by product. This heat warms the body. The brain reads temperature and controls to some extent the rate of this metabolism. There are also many other mechanisms triggered by the brain to keep the core of your body warm, even if the periphery (skin) is cold. Blood vessels to the fingers and toes constrict, so that the cold air doesn't cool the blood too much, so that cooled blood doesn't cool down the heart and brain when it returns. In severe cases, your body will sacrifice a finger or a toe to keep you from dying of cold core temperature (frostbite: it saves your life!). Also the brain can order a lot of muscles to contract rapidly. This generates a lot of heat quickly, a response called shivering. There's much more to this exciting field of research.

High Temperature Capacitor Development  

Science Conference Proceedings (OSTI)

The absence of high-temperature electronics is an obstacle to the development of untapped energy resources (deep oil, gas and geothermal). US natural gas consumption is projected to grow from 22 trillion cubic feet per year (tcf) in 1999 to 34 tcf in 2020. Cumulatively this is 607 tcf of consumption by 2020, while recoverable reserves using current technology are 177 tcf. A significant portion of this shortfall may be met by tapping deep gas reservoirs. Tapping these reservoirs represents a significant technical challenge. At these depths, temperatures and pressures are very high and may require penetrating very hard rock. Logistics of supporting 6.1 km (20,000 ft) drill strings and the drilling processes are complex and expensive. At these depths up to 50% of the total drilling cost may be in the last 10% of the well depth. Thus, as wells go deeper it is increasingly important that drillers are able to monitor conditions down-hole such as temperature, pressure, heading, etc. Commercial off-the-shelf electronics are not specified to meet these operating conditions. This is due to problems associated with all aspects of the electronics including the resistors and capacitors. With respect to capacitors, increasing temperature often significantly changes capacitance because of the strong temperature dependence of the dielectric constant. Higher temperatures also affect the equivalent series resistance (ESR). High-temperature capacitors usually have low capacitance values because of these dielectric effects and because packages are kept small to prevent mechanical breakage caused by thermal stresses. Electrolytic capacitors do not operate at temperatures above 150oC due to dielectric breakdown. The development of high-temperature capacitors to be used in a high-pressure high-temperature (HPHT) drilling environment was investigated. These capacitors were based on a previously developed high-voltage hybridized capacitor developed at Giner, Inc. in conjunction with a unique high-temperature electrolyte developed during the course of the program. During this program the feasibility of operating a high voltage hybridized capacitor at 230oC was demonstrated. Capacitor specifications were established in conjunction with potential capacitor users. A method to allow for capacitor operation at both ambient and elevated temperatures was demonstrated. The program was terminated prior to moving into Phase II due to a lack of cost-sharing funds.

Continuous Severe Plastic Deformation Processing of Aluminum Alloys  

SciTech Connect

Metals with grain sizes smaller than 1-micrometer have received much attention in the past decade. These materials have been classified as ultra fine grain (UFG) materials (grain sizes in the range of 100 to 1000-nm) and nano-materials (grain size <100-nm) depending on the grain size. This report addresses the production of bulk UFG metals through the use of severe plastic deformation processing, and their subsequent use as stock material for further thermomechanical processing, such as forging. A number of severe plastic deformation (SPD) methods for producing bulk UFG metals have been developed since the early 1990s. The most promising of these processes for producing large size stock that is suitable for forging is the equal channel angular extrusion or pressing (ECAE/P) process. This process involves introducing large shear strain in the work-piece by pushing it through a die that consists of two channels with the same cross-sectional shape that meet at an angle to each other. Since the cross-sections of the two channels are the same, the extruded product can be re-inserted into the entrance channel and pushed again through the die. Repeated extrusion through the ECAE/P die accumulates sufficient strain to breakdown the microstructure and produce ultra fine grain size. It is well known that metals with very fine grain sizes (< 10-micrometer) have higher strain rate sensitivity and greater elongation to failure at elevated temperature, exhibiting superplastic behavior. However, this superplastic behavior is usually manifest at high temperature (> half the melting temperature on the absolute scale) and very low strain rates (< 0.0001/s). UFG metals have been shown to exhibit superplastic characteristics at lower temperature and higher strain rates, making this phenomenon more practical for manufacturing. This enables part unitization and forging more complex and net shape parts. Laboratory studies have shown that this is particularly true for UFG metals produced by SPD techniques. This combination of properties makes UFG metals produced by SPD very attractive as machining, forging or extrusion stock, both from the point of view of formability as well as energy and cost saving. However, prior to this work there had been no attempt to transfer these potential benefits observed in the laboratory scale to industrial shop floor. The primary reason for this was that the laboratory scale studies had been conducted to develop a scientific understanding of the processes that result in grain refinement during SPD. Samples that had been prepared in the laboratory scale were typically only about 10-mm diameter and 50-mm long (about 0.5-inch diameter and 2-inches long). The thrust of this project was three-fold: (i) to show that the ECAE/P process can be scaled up to produce long samples, i.e., a continuous severe plastic deformation (CSPD) process, (ii) show the process can be scaled up to produce large cross section samples that could be used as forging stock, and (iii) use the large cross-section samples to produce industrial size forgings and demonstrate the potential energy and cost savings that can be realized if SPD processed stock is adopted by the forging industry. Aluminum alloy AA-6061 was chosen to demonstrate the feasibility of the approach used. The CSPD process developed using the principles of chamber-less extrusion and drawing, and was demonstrated using rolling and wire drawing equipment that was available at Oak Ridge National Laboratory. In a parallel effort, ECAE/P dies were developed for producing 100-mm square cross section SPD billets for subsequent forging. This work was carried out at Intercontinental Manufacturing Co. (IMCO), Garland TX. Forging studies conducted with the ECAE/P billets showed that many of the potential benefits of using UFG material can be realized. In particular, the material yield can be increased, and the amount of material that is lost as scrap can be reduced by as much as 50%. Forging temperatures can also be reduced by over 150C, resulting in energy savings in the ope

Continuous cryopump with a device for regenerating the cryosurface  

DOE Patents (OSTI)

A high throughput continuous cryopump is provided. The cryopump incorporates an improved method for regenerating the cryopumping surface while the pump is in continuous operation. The regeneration of the cryopumping surface does not thermally cycle the pump, and to this end a small chamber connected to a secondary pumping source serves to contain and exhaust frost removed from the cryopumping surface during such regeneration. The frost is exhausted at a rate substantially independent of the speed of the cryopump which enhances the capability of the pump to achieve a high compression ratio and allow the pump to operate continuously while the cryopumping surface is being regenerated. 8 figs.

Absorber Materials at Room and Cryogenic Temperatures  

Science Conference Proceedings (OSTI)

We recently reported on investigations of RF absorber materials at cryogenic temperatures conducted at Jefferson Laboratory (JLab). The work was initiated to find a replacement material for the 2 Kelvin low power waveguide Higher Order Mode (HOM) absorbers employed within the original cavity cryomodules of the Continuous Electron Beam Accelerator Facility (CEBAF). This effort eventually led to suitable candidates as reported in this paper. Furthermore, though constrained by small funds for labor and resources, we have analyzed a variety of lossy ceramic materials, several of which could be usable as HOM absorbers for both normal conducting and superconducting RF structures, e.g. as loads in cavity waveguides and beam tubes either at room or cryogenic temperatures and, depending on cooling measures, low to high operational power levels.

The high temperature phosphor is in contact with an article whose temperature is to be determined. The article having the phosphor in contact with it is placed in the environment for which the temperature of the article is to be determined. The phosphor is excited by a laser causing the phosphor to fluoresce. The emission from the phosphor is optically focused into a beam-splitting mirror which separates the emission into two separate emissions, the emission caused by the dysprosium dopant and the emission caused by the europium dopent. The separated emissions are optically filtered and the intensities of the emission are detected and measured. The ratio of the intensity of each emission is determined and the temperature of the article is calculated from the ratio of the intensities of the separate emissions.

Monte Carlo tools in SCALE are commonly used in criticality safety calculations as well as sensitivity and uncertainty analysis, depletion, and criticality alarm system analyses. Recent improvements in the continuous-energy data generated by the AMPX code system and significant advancements in the continuous-energy treatment in the KENO Monte Carlo eigenvalue codes facilitate the use of SCALE Monte Carlo codes to model geometrically complex systems with enhanced solution fidelity. The addition of continuous-energy treatment to the SCALE Monaco code, which can be used with automatic variance reduction in the hybrid MAVRIC sequence, provides significant enhancements, especially for criticality alarm system modeling. This paper describes some of the advancements in continuous-energy Monte Carlo codes within the SCALE code system.

We construct the gravity background which describes the dual field theory with aging invariance. We choose the decay modes of the bulk scalar field in the internal spectator direction to obtain the dissipative behavior of the boundary correlation functions of the dual scalar fields. In particular, the two-time correlation function at zero temperature has the characteristic features of the aging system: power law decay, broken time translation and dynamical scaling. We also construct the black hole backgrounds with asymptotic aging invariance. We extensively study characteristic behavior of the finite temperature two-point correlation function via analytic and numerical methods.

A method for determining the temperature of a surface upon which a coating is grown using optical pyrometry by correcting Kirchhoff's law for errors in the emissivity or reflectance measurements associated with the growth of the coating and subsequent changes in the surface thermal emission and heat transfer characteristics. By a calibration process that can be carried out in situ in the chamber where the coating process occurs, an error calibration parameter can be determined that allows more precise determination of the temperature of the surface using optical pyrometry systems. The calibration process needs only to be carried out when the physical characteristics of the coating chamber change.

Fluorescent temperature sensor  

Science Conference Proceedings (OSTI)

The present invention is a fluorescent temperature sensor or optical thermometer. The sensor includes a solution of 1,3-bis(1-pyrenyl)propane within a 1-butyl-1-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ionic liquid solvent. The 1,3-bis(1-pyrenyl)propane remains unassociated when in the ground state while in solution. When subjected to UV light, an excited state is produced that exists in equilibrium with an excimer. The position of the equilibrium between the two excited states is temperature dependent.

The continuity of the output entropy of positive maps  

SciTech Connect

Global and local continuity conditions for the output von Neumann entropy for positive maps between Banach spaces of trace-class operators in separable Hilbert spaces are obtained. Special attention is paid to completely positive maps: infinite dimensional quantum channels and operations. It is shown that as a result of some specific properties of the von Neumann entropy (as a function on the set of density operators) several results on the output entropy of positive maps can be obtained, which cannot be derived from the general properties of entropy type functions. In particular, it is proved that global continuity of the output entropy of a positive map follows from its finiteness. A characterization of positive linear maps preserving continuity of the entropy (in the following sense: continuity of the entropy on an arbitrary subset of input operators implies continuity of the output entropy on this subset) is obtained. A connection between the local continuity properties of two completely positive complementary maps is considered. Bibliography: 21 titles.

Performance assessment on continuous air monitors under real operating conditions  

Science Conference Proceedings (OSTI)

In the nuclear industry, workers may be exposed to artificial radioactive aerosols. These aerosols are generally composed of particles with a diameter measuring between 0.1 {mu}m and 10 {mu}m. To protect workers in nuclear facilities, monitors that continuously measure radioactivity in the air are used. The main function of the monitor is to provide real-time measurement of activity concentration. Measurement of aerosol activity concentration can be affected by a number of factors specific to the aerosols and the instrument. The first part of the article will present the general operating principles of continuous air monitors (CAMs) and inherent measurement difficulties, as well as the main standard tests. The second section describes the experimental ICARE facility The ICARE facility generates standard artificial and natural radioactive aerosols for calibrating continuous air monitors under real operating conditions.

Autoignited laminar lifted flames of methane, ethylene, ethane, and n-butane jets in coflow air with elevated temperature  

Science Conference Proceedings (OSTI)

The autoignition characteristics of laminar lifted flames of methane, ethylene, ethane, and n-butane fuels have been investigated experimentally in coflow air with elevated temperature over 800 K. The lifted flames were categorized into three regimes depending on the initial temperature and fuel mole fraction: (1) non-autoignited lifted flame, (2) autoignited lifted flame with tribrachial (or triple) edge, and (3) autoignited lifted flame with mild combustion. For the non-autoignited lifted flames at relatively low temperature, the existence of lifted flame depended on the Schmidt number of fuel, such that only the fuels with Sc > 1 exhibited stationary lifted flames. The balance mechanism between the propagation speed of tribrachial flame and local flow velocity stabilized the lifted flames. At relatively high initial temperatures, either autoignited lifted flames having tribrachial edge or autoignited lifted flames with mild combustion existed regardless of the Schmidt number of fuel. The adiabatic ignition delay time played a crucial role for the stabilization of autoignited flames. Especially, heat loss during the ignition process should be accounted for, such that the characteristic convection time, defined by the autoignition height divided by jet velocity was correlated well with the square of the adiabatic ignition delay time for the critical autoignition conditions. The liftoff height was also correlated well with the square of the adiabatic ignition delay time. (author)

Research Article Continuous Production of Lipase-Catalyzed Biodiesel in a Packed-Bed Reactor: Optimization and Enzyme Reuse Study  

E-Print Network (OSTI)

Copyright 2011 Hsiao-Ching Chen et al. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. An optimal continuous production of biodiesel by methanolysis of soybean oil in a packed-bed reactor was developed using immobilized lipase (Novozym 435) as a catalyst in a tert-butanol solvent system. Response surface methodology (RSM) and Box-Behnken design were employed to evaluate the effects of reaction temperature, flow rate, and substrate molar ratio on the molar conversion of biodiesel. The results showed that flow rate and temperature have significant effects on the percentage of molar conversion. On the basis of ridge max analysis, the optimum conditions were as follows: flow rate 0.1 mL/min, temperature 52.1 ? C, and substrate molar ratio 1: 4. The predicted and experimental values of molar conversion were 83.31 2.07 % and 82.81 .98%, respectively. Furthermore, the continuous process over 30 days showed no appreciable decrease in the molar conversion. The paper demonstrates the applicability of using immobilized lipase and a packed-bed reactor for continuous biodiesel synthesis. 1.

LSA large area silicon sheet task continuous liquid feed Czochralski growth. Quarterly report, July-September 1979  

DOE Green Energy (OSTI)

This project, currently in its second phase, is directed toward the design and development of equipment and processes to demonstrate continuous growth of crystals by the Czochralski method, suitable for producing single silicon crystals for use in solar cells. Continuous is defined as the growth of at least 150 kg of monosilicon crystal, 150 mm in diameter, from one growth container. The approach to meeting this goal is to develop a furnace with continuous liquid replenishment of the growth crucible, accomplished by a meltdown system with a continuous solid silicon fedd methanism and a liquid transfer system, with associated automatic feedback controls. In order to establish process parameters for conventional CZ growth of 150 mm ingots, several runs with 12-kg charges were performed, and solidification rates of 2.7 to 3.5 kg/hr were achieved. Significant progress has been made in the development of a new melt transfer system. Basic material problems relating to the high temperature environment were solved. The cost of the new transfer mechanism is lowered substantially through multiple use of the major system components. Manufacturing of parts and installation of the polyrod feed mechanism for continuous recharging of the meltdown chamber were completed together with the feedback control system which uses the melt level sensor belonging to the growth crucible as input. The design for a continuous particle feeder into the meltdown chamber has been completed, and the fabrication of this system is currently in progress. Several short melt replenishment runs with 5 to 8 kg of continuous melt transfer were performed in an effort to develop feedback control systems for solid rod and particle feeding as well as to establish the permissible pressure region in which melt transfer can be assured.

It is found that thermal plumes are not emitted periodically, but randomly and continuously, from the top and bottom plates. We further found that the oscillation of the temperature field does not originate from the boundary layers, but rather is a result of the horizontal motion of the hot ascending and cold descending fluids being modulated by the twisting and sloshing motion of the bulk flow field.

LOW TEMPERATURE CATHODE SUPPORTED ELECTROLYTES  

DOE Green Energy (OSTI)

This project has three main goals: Thin Films Studies, Preparation of Graded Porous Substrates and Basic Electrical Characterization and testing of Planar Single Cells. This period has continued to address the problem of making dense 1/2 to 5 {micro}m thick dense layers on porous substrates (the cathode LSM). Our current status is that we are making structures of 2-5 cm{sup 2} in area, which consist of either dense YSZ or CGO infiltrated into a 2-5 {micro}m thick 50% porous layer made of either nanoncrystalline CGO or YSZ powder. This composite structure coats a macroporous cathode or anode; which serves as the structural element of the bi-layer structure. These structures are being tested as SOFC elements. A number of structures have been evaluated both as symmetrical and as button cell configuration. Results of this testing indicates that the cathodes contribute the most to cell losses for temperatures below 750 C. In this investigation different cathode materials were studied using impedance spectroscopy of symmetric cells and IV characteristics of anode supported fuel cells. Cathode materials studied included La{sub 0.8}Sr{sub 0.2}Co{sub 0.2}Fe{sub 0.8}O{sub 3} (LSCF), La{sub 0.7}Sr{sub 0.2}MnO{sub 3} (LSM), Pr{sub 0.8}Sr{sub 0.2}Fe{sub 0.8}O{sub 3} (PSCF), Sm{sub 0.8}Sr{sub 0.2}Co{sub 0.2}Fe{sub 0.8}O{sub 3} (SSCF), and Yb{sub .8}Sr{sub 0.2}Co{sub 0.2}Fe{sub 0.8}O{sub 3} (SSCF). A new technique for filtering the Fourier transform of impedance data was used to increase the sensitivity of impedance analysis. By creating a filter specifically for impedance spectroscopy the resolution was increased. The filter was tailored to look for specific circuit elements like R//C, Warburg, or constant phase elements. As many as four peaks can be resolved using the filtering technique on symmetric cells. It may be possible to relate the different peaks to material parameters, like the oxygen exchange coefficient. The cathode grouped in order from lowest to highest ASR is LSCF < PSCF < SSCF < YSCF < LSM. The button cell results agree with this ordering indicating that this is an important tool for use in developing our understanding of electrode behavior in fuel cells.

Operation of a Pressurized System for Continuous Reduction of CO2  

Science Conference Proceedings (OSTI)

A Ag-based pressurized electrochemical system equipped for continuous reduction of CO2 is presented. At elevated pressures the quantity of CO which can be generated is 5 times that observed at ambient pressure with faradaic efficiencies as high as 92% observed at 350 mA cm-2. For operation at 225 mA cm-2 and 60 degrees C the cell voltage at 18.5 atm was 0.4 V below that observed at ambient pressure. Increasing the temperature further to 90 degrees C led to a cell voltage below 3 V (18.5 atm and 90 degrees C), which equates to an electrical efficiency of 50%.

General purpose dynamic Monte Carlo with continuous energy for transient analysis  

SciTech Connect

For safety assessments transient analysis is an important tool. It can predict maximum temperatures during regular reactor operation or during an accident scenario. Despite the fact that this kind of analysis is very important, the state of the art still uses rather crude methods, like diffusion theory and point-kinetics. For reference calculations it is preferable to use the Monte Carlo method. In this paper the dynamic Monte Carlo method is implemented in the general purpose Monte Carlo code Tripoli4. Also, the method is extended for use with continuous energy. The first results of Dynamic Tripoli demonstrate that this kind of calculation is indeed accurate and the results are achieved in a reasonable amount of time. With the method implemented in Tripoli it is now possible to do an exact transient calculation in arbitrary geometry. (authors)

Continuous variable quantum teleportation with non-Gaussian resources  

E-Print Network (OSTI)

We investigate continuous variable quantum teleportation using non-Gaussian states of the radiation field as entangled resources. We compare the performance of different classes of degaussified resources, including two-mode photon-added and two-mode photon-subtracted squeezed states. We then introduce a class of two-mode squeezed Bell-like states with one-parameter dependence for optimization. These states interpolate between and include as subcases different classes of degaussified resources. We show that optimized squeezed Bell-like resources yield a remarkable improvement in the fidelity of teleportation both for coherent and nonclassical input states. The investigation reveals that the optimal non-Gaussian resources for continuous variable teleportation are those that most closely realize the simultaneous maximization of the content of entanglement, the degree of affinity with the two-mode squeezed vacuum and the, suitably measured, amount of non-Gaussianity.

Continuous measurement of a microwave-driven solid state qubit  

E-Print Network (OSTI)

We analyze the dynamics of a continuously observed, damped, microwave driven solid state charge qubit. The qubit consists of a single electron in a double well potential, coupled to an oscillating electric field, and which is continuously observed by a nearby point contact electrometer. The microwave field induces transitions between the qubit eigenstates, which have a profound effect on the detector output current. We show that useful information about the qubit dynamics, such as dephasing and relaxation rates, and the Rabi frequency, can be extracted from the DC detector conductance and the detector output noise power spectrum. We also demonstrate that these phenomena can be used for single shot electron \\emph{spin} readout, for spin based quantum information processing.

Steiner Symmetrization Is Continuous In W 1,P  

E-Print Network (OSTI)

We study the continuity, smoothing, and convergence properties of Steiner symmetrization in higher space dimensions. Our main result is that Steiner symmetrization is continuous in W 1;p (1 p ! 1) in all dimensions. This implies that spherical symmetrization cannot be approximated in W 1;p by sequences of Steiner symmetrizations. We also give a quantitative version of the standard energy inequalities for spherical symmetrization. 1 Introduction Steiner symmetrization was invented as a tool for a geometric proof of the isoperimetric inequality. The isoperimetric inequality says that among all bodies of a given volume, the ball has the smallest perimeter; or, in the language of rearrangements, that the perimeter of a body can only decrease under spherical symmetrization. Steiner observed that the perimeter of a body is generally larger than the perimeter of a related body of the same volume which is symmetric at a hyperplane; or, as we would say, that the perimeter of the body decr...

Continuous variable entanglement distillation of Non-Gaussian Mixed States  

E-Print Network (OSTI)

Many different quantum information communication protocols such as teleportation, dense coding and entanglement based quantum key distribution are based on the faithful transmission of entanglement between distant location in an optical network. The distribution of entanglement in such a network is however hampered by loss and noise that is inherent in all practical quantum channels. Thus, to enable faithful transmission one must resort to the protocol of entanglement distillation. In this paper we present a detailed theoretical analysis and an experimental realization of continuous variable entanglement distillation in a channel that is inflicted by different kinds of non-Gaussian noise. The continuous variable entangled states are generated by exploiting the third order non-linearity in optical fibers, and the states are sent through a free-space laboratory channel in which the losses are altered to simulate a free-space atmospheric channel with varying losses. We use linear optical components, homodyne mea...

Using Whole-Building Electric Load Data in Continuous or Retro-Commissioning  

SciTech Connect

Whole-building electric load data can often reveal problems with building equipment or operations. In this paper, we present methods for analyzing 15-minute-interval electric load data. These methods allow building operators, energy managers, and commissioning agents to better understand a building's electricity consumption over time and to compare it to other buildings, helping them to 'ask the right questions' to discover opportunities for electricity waste elimination, energy efficiency, peak load management, and demand response. For example: Does the building use too much energy at night, or on hot days, or in the early evening? Knowing the answer to questions like these can help with retro-commissioning or continuous commissioning. The methods discussed here can also be used to assess how building energy performance varies with time. Comparing electric load before and after fixing equipment or changing operations can help verify that the fixes have the intended effect on energy consumption. Analysis methods discussed in this paper include: ways to graphically represent electric load data; the definition of various parameters that characterize facility electricity loads; and a regression-based electricity load model that accounts for both time of week and outdoor air temperature. The methods are illustrated by applying them to data from commercial buildings. We demonstrate the ability to recognize changes in building operation, and to quantify changes in energy performance. Some key findings are: 1) Plotting time series electric load data is useful for understanding electricity consumption patterns and changes to those patterns, but results may be misleading if data from different time intervals are not weather-normalized. 2) Parameter plots can highlight key features of electric load data and may be easier to interpret than plots of time series data themselves. 3) A time-of-week indicator variable (as compared to time-of-day and day-of-week indicator variables) improves the accuracy of regression models of electric load. 4) A piecewise linear and continuous outdoor air temperature dependence can be derived without the use of a change-point model (which would add complexity to the modeling algorithm) or assumptions about when structural changes occur (which could introduce inaccuracy). 5) A model that includes time-of-week and temperature dependence can be used for weather normalization and can determine whether the building is unusually temperature-sensitive, which can indicate problems with HVAC operation.

We describe an iterative optimization algorithm developed for continuous contour phase plate design. With the help of this algorithm, a kinoform plate was designed to transform the square supergaussian beam into round supergaussian one. The phase function derived by the proposed method is smooth, has analytical representation, and has no singularities. Drawback is that this function does not provide smoothing of the incoming intensity distribution like random phase plates do and output intensity should be sensitive to variations of the illuminating light amplitude.

Continuous Control and the Algebraic L-theory Assembly Map.  

E-Print Network (OSTI)

In this work, the assembly map in L-theory for the family of finite subgroups is proven to be a split injection for a class of groups. Groups in this class, including virtually polycyclic groups, have universal spaces that satisfy certain geometric conditions. The proof follows the method developed by Carlsson-Pedersen to split the assembly map in the case of torsion free groups. Here, the continuously controlled techniques and results are extended to handle groups with torsion.

Dephasing and collapse in continuous measurement of a single system  

E-Print Network (OSTI)

We show that long standing debates on the collapse and the role of the observer in quantum mechanics can be resolved experimentally via a nondistructive continuous monitoring of a single quantum system. An example of such a system, coupled with the point-contact detector is presented. The detailed quantum mechanical analysis of the entire system (including the detector) shows that under certain conditions the measurement collapse would generate distinctive effects in the detector behavior, which can be experimentally investigated.

Quantification and scaling of multipartite entanglement in continuous variable systems  

E-Print Network (OSTI)

We present a theoretical method to determine the multipartite entanglement between different partitions of multimode, fully or partially symmetric Gaussian states of continuous variable systems. For such states, we determine the exact expression of the logarithmic negativity and show that it coincides with that of equivalent two--mode Gaussian states. Exploiting this reduction, we demonstrate the scaling of the multipartite entanglement with the number of modes and its reliable experimental estimate by direct measurements of the global and local purities.

Continuous production of ethanol by use of flocculent Zymomonas mobilis  

DOE Patents (OSTI)

Improved means and process for producing ethanol by fermentation are provided. Another object of the invention is to produce ethanol in a continuous-flow process by means of a biological catalyst that can be retained in a continuous-flow reactor vessel without being bonded to or held within a support material. An additional object of the invention is to provide a fermentation reactor vessel wherein disturbance of the desirable plug flow of sugar solution is minimized. These objects are attained by the preferred apparatus and process of the invention which utilize a newly-discovered flocculent strain of Zymomonas mobilis for converting sugar to ethanol in a continuous flow-type reactor vessel. The flow rate of a sugar-containing solution through a column containing the floc-forming strain of Z. mobilis is adjusted so that a sufficient conversion of sugar to ethanol is achieved in the column and the flocculent Z. mobilis is not washed away in effluent from the column. Carbon dioxide gas generated by the fermentation process is vented from a plurality of points spaced along an inclined column in which the process is conducted, thus minimizing disturbance of the plug flow of liquid by this gas.

Large-Scale Continuous Subgraph Queries on Streams  

SciTech Connect

Graph pattern matching involves finding exact or approximate matches for a query subgraph in a larger graph. It has been studied extensively and has strong applications in domains such as computer vision, computational biology, social networks, security and finance. The problem of exact graph pattern matching is often described in terms of subgraph isomorphism which is NP-complete. The exponential growth in streaming data from online social networks, news and video streams and the continual need for situational awareness motivates a solution for finding patterns in streaming updates. This is also the prime driver for the real-time analytics market. Development of incremental algorithms for graph pattern matching on streaming inputs to a continually evolving graph is a nascent area of research. Some of the challenges associated with this problem are the same as found in continuous query (CQ) evaluation on streaming databases. This paper reviews some of the representative work from the exhaustively researched field of CQ systems and identifies important semantics, constraints and architectural features that are also appropriate for HPC systems performing real-time graph analytics. For each of these features we present a brief discussion of the challenge encountered in the database realm, the approach to the solution and state their relevance in a high-performance, streaming graph processing framework.

Norm continuous unitary representations of Lie algebras of smooth sections  

E-Print Network (OSTI)

We give a complete description of the bounded (i.e. norm continuous) unitary representations of the Fr\\'echet-Lie algebra of all smooth sections, as well as of the LF-Lie algebra of compactly supported smooth sections, of a smooth Lie algebra bundle whose typical fiber is a compact Lie algebra. For the Lie algebra of all sections, bounded unitary irreducible representations are finite tensor products of so-called evaluation representations, hence in particular finite-dimensional. For the Lie algebra of compactly supported sections, bounded unitary irreducible (factor) representations are possibly infinite tensor products of evaluation representations, which reduces the classification problem to results of Glimm and Powers on irreducible (factor) representations of UHF C*-algebras. The key part in our proof is the classification of irreducible bounded unitary representations of Lie algebras that are the tensor product of a compact Lie algebra and a unital real continuous inverse algebra: every such representation is a finite product of evaluation representations. On the group level, our results cover in particular the bounded unitary representations of the identity component of the group of smooth gauge transformations of a principal fiber bundle with compact base and structure group, and the connected component of the group of special unitary n times n matrices with values in an involutive commutative continuous inverse algebra.

Commercialization of a high-performance continuous reforming catalyst  

Science Conference Proceedings (OSTI)

In 1971, the first CCR Platforming process was started up in the US on the Gulf Coast. Twenty-two years later, more than 108 continuous reforming units are operating worldwide. Another 50 CCR Platforming units are in various stages of design, construction, or start-up. Continuous catalytic reforming now represents more than 25% of the world's reforming capacity. Throughout these three decades, the UOP CCR Platforming technology continuously improved in terms of catalyst and process in response to changing industry requirements. Processing conditions in 1993 place tremendous demands on the catalyst in the reforming unit. This paper reviews the challenges and needs of the changing refining industry and the development of a new generation of CCR Platforming catalyst, R-132, and focuses on the first commercial operation of this high-activity, surface-stable catalyst. Case studies show how a refiner can improve margins by using the high activity, yield stability, longer life, and improved chloride retention benefits of this new R-132 Platforming catalyst.

Extremal entanglement and mixedness in continuous variable systems  

E-Print Network (OSTI)

We investigate the relationship between mixedness and entanglement for Gaussian states of continuous variable systems. We introduce generalized entropies based on Schatten $p$-norms to quantify the mixedness of a state, and derive their explicit expressions in terms of symplectic spectra. We compare the hierarchies of mixedness provided by such measures with the one provided by the purity (defined as ${\\rm tr} \\varrho^2$ for the state $\\varrho$) for generic $n$-mode states. We then review the analysis proving the existence of both maximally and minimally entangled states at given global and marginal purities, with the entanglement quantified by the logarithmic negativity. Based on these results, we extend such an analysis to generalized entropies, introducing and fully characterizing maximally and minimally entangled states for given global and local generalized entropies. We compare the different roles played by the purity and by the generalized $p$-entropies in quantifying the entanglement and the mixedness of continuous variable systems. We introduce the concept of average logarithmic negativity, showing that it allows a reliable quantitative estimate of continuous variable entanglement by direct measurements of global and marginal generalized $p$-entropies.

Continuous multi-phase feeding of broiler chickens  

E-Print Network (OSTI)

Continuous multi-phase feeding of broiler chickens was evaluated to optimize broiler nutrition and minimize environmental impact related to excess nitrogen in poultry manure. Four experiments were conducted. Experiments 1 and 2 studied effects of continuous multi-phase feeding during a 3-week starting period using battery brooders while experiments 3 and 4 evaluated multi-phase feeding during a traditional 7-week growing period using both battery brooders and floor pens. In the first and second experiments, the nutrient content of the multi-phase diets was changed every 24 hours in comparison to single-phase feeding. Results indicated that during the starter period, continuous multi-phase feeding had no significant influence on feed consumption, daily gain, feed to gain ratio or fecal nitrogen. In the third and fourth experiments, a four phase industry type broiler feeding program was compared to intensive multi-phase feeding programs created by linearly blending three different diets based on typical industry nutrient values and a commercial nutrient modeling computer program (EFG Natal). In both intensive multi-phase feeding programs, the diets were changed every three days over a 7-week growth period. Broilers in experiment 3 were raised in Petersime battery brooders to primarily access nitrogen balance while birds in experiment 4 were raised in a floor pen on pine shaving litter to resemble commercial broiler production. The results indicated that intensive multi-phase feeding improved body weight gain and feed to gain ratio only in weeks 5 and 6 but not during the overall 7-week period. Nitrogen excretion and nitrogen retention were unaffected by the intensive multi-phase feeding systems. Economic analysis indicated that intensive multi-phase feeding programs could potentially lower feed costs per kilogram of gain. However, the high cost of implementing a continuous multi-phase feeding system may not justify the relatively small gain in lower feed cost per kilogram of gain. In conclusion, continuous multi-phase feeding of broiler chickens using corn-soy diets does not appear to be justified by either increased performance or reduced nitrogen excretion.

High temperature interfacial superconductivity  

DOE Patents (OSTI)

High-temperature superconductivity confined to nanometer-scale interfaces has been a long standing goal because of potential applications in electronic devices. The spontaneous formation of a superconducting interface in bilayers consisting of an insulator (La.sub.2CuO.sub.4) and a metal (La.sub.1-xSr.sub.xCuO.sub.4), neither of which is superconducting per se, is described. Depending upon the layering sequence of the bilayers, T.sub.c may be either .about.15 K or .about.30 K. This highly robust phenomenon is confined to within 2-3 nm around the interface. After exposing the bilayer to ozone, T.sub.c exceeds 50 K and this enhanced superconductivity is also shown to originate from a 1 to 2 unit cell thick interfacial layer. The results demonstrate that engineering artificial heterostructures provides a novel, unconventional way to fabricate stable, quasi two-dimensional high T.sub.c phases and to significantly enhance superconducting properties in other superconductors. The superconducting interface may be implemented, for example, in SIS tunnel junctions or a SuFET.
