Analysis of a high-temperature heat exchanger for an externally-fired micro gas turbine  

Science Journals Connector (OSTI)

Abstract The externally-fired gas turbine (EFGT) can convert fuels such as coal, biomass, biomass gasification gas and solar energy into electricity and heat. The combination of this technology with biomass gasification gas represents an interesting option for gasification, for which it has been difficult to find a conversion technology. In this system, the heat exchanger deals with the contaminants of biomass derived gas instead of the turbine itself. However, these contaminants can build a deposit layer in the heat exchanger that can affect its performance. The heat exchanger is important in externally fired gas turbines since the turbine inlet temperature is directly dependent on its performance. Several studies on heat exchangers for externally fired gas turbines have been carried out. However, very few detailed studies were found comparing the performance of heat exchangers for externally fired gas turbines considering the effect of deposit materials on the surfaces. In this regard, this work compares the performance of a corrugated plate heat exchanger and a two-tube-passes shell and tube heat exchanger considering the effect of thickness of deposit material with different thermal conductivities on pressure drop and effectiveness. The results show that the effectiveness of the corrugated plate heat exchanger is more influenced at larger thicknesses of deposit materials than the two-tube-passes shell and tube heat exchanger. There is an exponential increase in the pressure drop of the plate heat exchanger while a monotonic increase of pressure drop is seen for the shell and tube heat exchanger. The increase in the thickness of the deposit material has two effects. On one hand, it increases the resistance to heat transfer and on the other hand, it reduces the through flow area increasing the velocity and hence the heat transfer coefficient. Additionally, the effectiveness of the heat exchangers had a stronger influence on the power output than the pressure drop.

Most of the water used in a thermoelectric power plant is used for cooling, and DOE has been focusing on possible techniques to reduce the amount of fresh water needed for cooling. DOE has also been placing emphasis on recovery of usable water from sources not generally considered, such as mine water, water produced from oil and gas extraction, and water contained in boiler flue gas. This report deals with development of condensing heat exchanger technology for recovering moisture from flue gas from coal-fired power plants. The report describes: (1) An expanded data base on water and acid condensation characteristics of condensing heat exchangers in coal-fired units. This data base was generated by performing slip stream tests at a power plant with high sulfur bituminous coal and a wet FGD scrubber and at a power plant firing high-moisture, low rank coals.

Hybrid heat exchange for the compression capture of CO2 from recirculated flue gas  

SciTech Connect (OSTI)

An approach proposed for removal of CO2 from flue gas cools and compresses a portion of a recirculated flue-gas stream, condensing its volatile materials for capture. Recirculating the flue gas concentrates SOx, H2O and CO2 while dramatically reducing N2 and NOx, enabling this approach, which uses readily available industrial components. A hybrid system of indirect and direct-contact heat exchange performs heat and mass transfer for pollutant removal and energy recovery. Computer modeling and experimentation combine to investigate the thermodynamics, heat and mass transfer, chemistry and engineering design of this integrated pollutant removal (IPR) system.

Flue gas carbon dioxide sequestration during water softening with ion-exchange fibers  

SciTech Connect (OSTI)

This study examines the use of ion-exchange fibers (IX fibers) to permanently sequester carbon dioxide present in flue gas into an aqueous phase as calcium or magnesium alkalinity while concurrently softening hard water. The only process inputs besides carbon dioxide (or flue gas) are snowmelt (or rainwater); no other chemicals are required for the regeneration of the IX fibers. Importantly, the process is not energy intensive and carbon dioxide does not need to be compressed to excessive pressures (>150 psi) for efficient use. Sources of carbon dioxide do not require concentration and, therefore, the use of raw flue gas (similar to 17% CO{sub 2}) is feasible with the rate of sequestration governed only by the partial pressure of carbon dioxide. While valid for flue gas obtained from any combustion process (e.g., coal, oil, natural gas, etc.), emissions from oil or gas combustion may be more appropriate for use in the described process due to the absence of mercury and particulates. It should also be noted that the presence of sulfur dioxide in flue gas would not adversely affect the process and may even enhance regeneration efficiency. The only product of the proposed process is an environmentally benign regenerant stream containing calcium and/or magnesium alkalinity. The unique property of IX fibers that makes the proposed process both environmentally sustainable and economically feasible is amenability to efficient regeneration with carbon dioxide and harvested snowmelt. Low intraparticle diffusional resistance is the underlying reason why IX fibers are amenable to efficient regeneration using snowmelt sparged with carbon dioxide; 95% calcium recovery was attained at a CO{sub 2} partial pressure of 6.8 atm. The energy balance for a typical electric utility shows that up to 1% of carbon dioxide emitted during combustion would be sequestered in the softening process.

Effects of cumulus clouds on microclimate and shoot-level photosynthetic gas exchange in Picea engelmannii and Abies lasiocarpa at treeline, Medicine Bow Mountains, Wyoming, USA  

Science Journals Connector (OSTI)

Abstract Here we describe the dynamic effects of cumulus clouds on microclimate and shoot-level photosynthetic gas exchange in saplings of two treeline conifer speciesóPicea engelmannii and Abies lasiocarpa. Measurements were made during both clear-sky and partly cloudy conditions (?10Ė70% cumulus cloud cover) throughout the 2012 growing season within an alpine-treeline ecotone. Cumulus clouds generated dynamic fluctuations in photosynthetically active radiation (PAR), higher maximum PAR (>2500†?mol†m?2†s?1), 2Ė4 fold increases in diffuse PAR, reduced daily mean and cumulative PAR, lower needle temperatures, and reduced leaf-to-air vapor pressure differences relative to clear-sky conditions. Onset of cloud-shade corresponded with declines in photosynthesis, needle temperatures, and evapotranspiration, which were proportional to cloud duration and opacity. Despite increased diffuse light and greater sunlight intensity during cloud-gaps, photosynthesis was never higher on partly cloudy days compared to clear days in either species, during cloud-gaps or cloud-shade. However, reduced transpiration paired with photosynthesis comparable with clear-sky levels during cloud-gaps resulted in greater instantaneous water use efficiency relative to clear-sky measurements. There was no apparent photoinhibition of photosynthesis reflected in gas exchange measurements in response to abrupt and dramatic changes in PAR levels caused by cumulus clouds. We conclude that cumulus clouds reduce instantaneous and daily carbon gain, although lower needle temperatures and associated reductions in transpirational water loss may alleviate daily and seasonal water stress, thereby enhancing carbon gain over the growing season.

We report development and characterization of platinum doped carbon aerogel catalyst for catalytic exchange reactions between water and hydrogen gas. The carbon aerogel with uniformly dispersed platinum nanoparticles was prepared by adding platinum precursor during the sol-gel process. Thereafter colloidal PTFE was mixed with the platinum doped carbon aerogel powder and coated on Dixon rings to obtain hydrophobic catalyst with required mechanical strength. Detailed studies have been carried out to observe the effect of physical characteristics of the catalyst powder (surface area and pore size of aerogels Pt cluster size and its valence state etc) and the different coating parameters (PTFE to Pt-CA ratio and Pt loading on Dixon ring) on volume transfer rate (Ky.a) for H/D reaction. Ky.a values of ?0.8 m3 (STP).s?1. m?3 were obtained for Pt loading of 7% and Pt cluster size of 3 nm at atmospheric pressure.

Study on hydrophobicity degradation of gas diffusion layer in proton exchange membrane fuel cells  

Science Journals Connector (OSTI)

Abstract As one of the essential components of proton exchange membrane fuel cell (PEMFC), gas diffusion layer (GDL) is of importance on water management, as well on the performance and durability of PEMFC. In this paper, the hydrophobicity degradation of GDL was investigated by immersing it in the 1.0†mol†L?1 H2SO4 solution saturated by air for 1200†h. From the measurements of contact angle and water permeability, the hydrophobic characteristics of the pristine and immersed \\{GDLs\\} were compared. To investigate the causes for hydrophobicity degradation, the \\{GDLs\\} were analyzed by scanning electron microscopy, X-ray photoelectron spectroscopy and thermogravimetry. Further, the chemical compositions of H2SO4 solutions before and after immersion test were analyzed with infrared spectroscopy. Results showed that the hydrophobicity of immersed GDL decreased distinctly, which was caused by the damage of physical structure and surface characteristics. Moreover, the immersed GDL showed a worse fuel cell performance than the pristine GDL, especially under a low humidity condition.

Uncertainties in Air Exchange using Continuous-Injection, Long-Term Sampling Tracer-Gas Methods  

SciTech Connect (OSTI)

The PerFluorocarbon Tracer (PFT) method is a low-cost approach commonly used for measuring air exchange in buildings using tracer gases. It is a specific application of the more general Continuous-Injection, Long-Term Sampling (CILTS) method. The technique is widely used but there has been little work on understanding the uncertainties (both precision and bias) associated with its use, particularly given that it is typically deployed by untrained or lightly trained people to minimize experimental costs. In this article we will conduct a first-principles error analysis to estimate the uncertainties and then compare that analysis to CILTS measurements that were over-sampled, through the use of multiple tracers and emitter and sampler distribution patterns, in three houses. We find that the CILTS method can have an overall uncertainty of 10-15percent in ideal circumstances, but that even in highly controlled field experiments done by trained experimenters expected uncertainties are about 20percent. In addition, there are many field conditions (such as open windows) where CILTS is not likely to provide any quantitative data. Even avoiding the worst situations of assumption violations CILTS should be considered as having a something like a ?factor of two? uncertainty for the broad field trials that it is typically used in. We provide guidance on how to deploy CILTS and design the experiment to minimize uncertainties.

Evaluation of stack criteria pollutant gas absorption in the new generation thermoelectric water condenser fitted with laminar impinger type heat exchangers  

SciTech Connect (OSTI)

Title IV of the Clean Air Act Amendments of 1990 authorized the Environmental Protection Agency to establish an Acid Rain Program to reduce the adverse effects of acidic deposition. The Act specifically stipulated that CEMS (continuous emissions monitoring systems) be used to measure the stack emissions under this program. Along with these rules, comes the task of the Stack Tester (Reference Method) to routinely perform RATA (Relative Accuracy Test Audit) tests on the installed CEMS. This paper presents a laboratory and field test sequence to evaluate the signal attenuation through the gas sample conditioning, water condensation removal process, using laminar flow impinger heat exchangers. This method is compared to the EPA CFR 40, Part 60, Appendix A, Method 6, glass impinger train, commonly used by RATA stack testers. CFR 40, Part 75 revisions as of the CAAA 1990, requires more stringent certification and CEMS performance standards. These standards are summarized and related to gas absorption in both the thermoelectric cooler heat exchanger and the Method 6 glass impinger train system. As an incentive to reduce the frequency of RATA tests required per year, emitters are encouraged to achieve relative accuracies of 7.5% or less compared to the reference method. This incentive requires better reference method test apparatus definition. This paper will explore these alternatives and provide test data for comparison to the currently available apparatus. Also discussed is the theory of Electronic Gas Sample Coolers and their practical application to the removal of water from stack gas.

Baseline studies of surface gas exchange and soil-gas composition in preparation for CO{sub 2} sequestration research: Teapot Dome, Wyoming  

SciTech Connect (OSTI)

A baseline determination of CO{sub 2} and CH{sub 4} fluxes and soil-gas concentrations of CO{sub 2} and CH{sub 4} was made over the Teapot Dome oil field in the Naval Petroleum Reserve 3 in Natrona County, Wyoming, United States. This was done in anticipation of the experimentation with CO{sub 2} sequestration in the Pennsylvanian Tensleep Sandstone underlying the field at a depth of 1680 m. The measurements were made in January 2004 to capture the system with minimum biological activity in the soils, resulting in a minimum CO{sub 2} flux and a maximum CH{sub 4} flux. The CO{sub 2} fluxes were measured in the field with an infrared spectroscopic method. The CH{sub 4} fluxes were determined from gas-chromatographic measurements on discrete samples from under the flux chambers. The CO{sub 2} and CH{sub 4} were determined at 30-, 60-, and 100-cm depths in soil gas by gas chromatography. A total of 40 locations had triplicate flux measurements using 1.00-m{sup 2} chambers, and soil gas was sampled at single points at each of the 40 locations. Carbon dioxide fluxes averaged 227.1 CO{sub 2} m{sup -2} day{sup -1}, a standard deviation of 186.9 mg m{sup -2} day{sup -1}, and a range of - 281.7 to 732.9 mg m{sup -2} day{sup -1}, not including one location with subsurface infrastructure contamination. Methane fluxes averaged 0.137 mg CH{sub 4} m{sup -2} day{sup -1}, standard deviation of 0.326 mg m{sup -2} day{sup -1}, and a range of -0.481 to 1.14 mg m{sup -2} day{sup -1}, not including the same contaminated location.

Performance data of a proton exchange membrane fuel cell using H{sub 2}/CO as fuel gas  

SciTech Connect (OSTI)

The performance of a proton exchange membrane fuel cell (PEMFC) was evaluated at 80 C in H{sub 2} with defined amounts of CO (25 to 250 ppm) and pure oxygen. Membrane electrode assemblies (MEAs) were made using Nafion{trademark} 117 with carbon-supported dispersed Pt, Pt{sub 0.7}Ru{sub 0.3}, and Pt{sub 0.5}Ru{sub 0.5} as anode catalysts, and Pt as a cathode catalyst. For comparison the MEAs were first characterized in H{sub 2}/O{sub 2}. In H{sub 2}/CO//O{sub 2} steady-state current-voltage curves were obtained after a poisoning period. It was found that the performance of the cell depends strongly on the CO concentration and the anode catalyst used. For Pt{sub 0.5}Ru{sub 0.5} as anode catalyst, the maximum power density in H{sub 2}/CO//O{sub 2} was enhanced by a factor of four compared with a Pt anode catalyst. Using Pt{sub 0.5}Ru{sub 0.5} no difference in power density was found between pure H{sub 2} and H{sub 2}/100 ppm CO up to current densities of about 0.4 cm{sup {minus}2}.

Variation in soil moisture and N availability modulates carbon and water exchange in a California grassland experiment  

SciTech Connect (OSTI)

Variability in the magnitude and timing of precipitation is predicted to change under future climate scenarios. The primary objective of this study was to understand how variation in precipitation patterns consisting of soil moisture pulses mixed with intermittent dry down events influence ecosystem gas fluxes. We characterized the effects of precipitation amount and timing, N availability, and plant community composition on whole ecosystem and leaf gas exchange in a California annual grassland mesocosm study system that allowed precise control of soil moisture conditions. Ecosystem CO2 and fluxes increased significantly with greater precipitation and were positively correlated with soil moisture. A repeated 10 day dry down period following 11 days of variable precipitation inputs strongly depressed net ecosystem CO2 exchange (NEE) across a range of season precipitation totals, and plant community types. Ecosystem respiration (Re), evapotranspiration (ET) and leaf level photosynthesis (Amax) showed greatest sensitivity to dry down periods in low precipitation plots. Nitrogen additions significantly increased NEE, Re and Amax, particularly as water availability was increased. These results demonstrate that N availability and intermittent periods of soil moisture deficit (across a wide range of cumulative season precipitation totals) strongly modulate ecosystem gas exchange.

3-D agricultural air quality modeling: Impacts of NH3/H2S gasĖphase reactions and bi-directional exchange of NH3  

Science Journals Connector (OSTI)

Abstract Accurately simulating the transport and fate of reduced nitrogen (NHx†=†ammonia (NH3)†+†ammonium (NH4+))- and sulfur-containing compounds emitted from agricultural activities represents a major challenge in agricultural air quality modeling. In this study, the Community Multiscale Air Quality (CMAQ) modeling system is further developed and improved by implementing 22 ammonia (NH3)/hydrogen sulfide (H2S) related gas-phase reactions and adjusting a few key parameters (e.g., emission potential) for bi-directional exchange of NH3 fluxes. Several simulations are conducted over the eastern U.S. domain at a 12-km horizontal resolution for January and July 2002 to examine the impacts of those improved treatments on air quality. The 5th generation mesoscale model (MM5) and CMAQ predict an overall satisfactory and consistent performance with previous modeling studies, especially for 2-m temperature, 2-m relative humidity, ozone (O3), and fine particulate matter (PM2.5). High model biases exist for precipitation in July and also dry/wet depositions. The updated model treatments contribute to O3, NHx, and PM2.5 by up to 0.4†ppb, 1.0†?g†m?3, and 1.0†?g†m?3 in January, respectively, and reduce O3 by up to 0.8†ppb and contribute to \\{NHx\\} and PM2.5 by up to 1.2 and 1.1†?g†m?3 in July, respectively. The spatial distributions of O3 in both months and sulfur dioxide (SO2) in January are mainly affected by inline dry deposition velocity calculation. The spatial distributions of SO2 and sulfate (SO42?) in July are affected by both inline dry deposition velocity and NH3/H2S reactions. The variation trends of NH3, NHx, ammonium nitrate (NH4NO3), PM2.5 and total nitrogen (TN) are predominated by bi-directional exchange of NH3 fluxes. Uncertainties of NH3 emission potentials and empirical constants used in the bi-directional exchange scheme may significantly affect the concentrations of \\{NHx\\} and PM2.5, indicating that a more accurate and explicit treatment for those parameters should be considered in the future work.

Isotopic exchange measurements of the rates of adsorption/desorption and interconversion of CO and CO/sub 2/ over chromia-promoted magnetite: implications for water-gas shift  

SciTech Connect (OSTI)

Isotopic exchange measurements were used to investigate the adsorption/desorption and interconversion of CO and CO/sub 2/ on chromia-promoted magnetite at 565 and 627 K. The interconversion between CO and CO/sub 2/ was shown to take place through surface adsorbed species. Furthermore, the rate of interconversion was limited by the rates of adsorption/desorption, indicating either that adsorbed CO and CO/sub 2/ are in equilibrium on the surface or that the adsorption of CO and CO/sub 2/ leads to the same surface species, e.g., a surface carbonate species. A kinetic model for the water-gas shift over magnetite is proposed, and the results of the isotopic exchange measurements and volumetric adsorption data are used to estimate the rate and equilibrium constants for this model.

Stand-Level Gas-Exchange Responses to Seasonal Drought in Very Young Versus Old Douglas-fir Forests of the Pacific Northwest, USA  

SciTech Connect (OSTI)

This study examines how stand age affects ecosystem mass and energy exchange response to seasonal drought in three adjacent Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) forests. The sites include two early seral stands (ES) (0-15 years old) and an old-growth (OG) ({approx} 450-500) forest in the Wind River Experiment Forest, Washington, USA. We use eddy covariance flux measurements of carbon dioxide (F{sub NEE}), latent energy ({lambda}E) and sensible heat (H) to derive evapotranspiration rate (E{sub T}), bowen ratio ({beta}), water use efficiency (WUE), canopy conductance (G{sub c}), the Priestley-Taylor coefficient ({alpha}) and a canopy decoupling factor ({Omega}). The canopy and bulk parameters are examined to see how ecophysiological responses to water stress, including changes in available soil water ({theta}{sub r}) and vapor pressure deficit ({delta}e) differ among the two forest successional-stages. Despite very different rainfall patterns in 2006 and 2007, we observed distinct successional-stage relationships between E{sub T}, {alpha}, and G{sub c} to {delta}e and {theta}{sub r} during both years. The largest stand differences were (1) higher morning G{sub c} (> 10 mm s{sup -1}) at the OG forest coinciding with higher CO{sub 2} uptake (F{sub NEE} = -9 to -6 {micro}mol m{sup -2} s{sup -1}) but a strong negative response in G{sub c} to moderate {delta}e later in the day and a subsequent reduction in E{sub T}, and (2) higher E{sub T} at the ES stands because midday canopy conductance did not decrease until very low water availability levels (<30%) were reached at the end of the summer. Our results suggest that early seral stands are more likely than mature forests to experience declines in production if the summer drought becomes longer or intensifies because water conserving ecophysiological responses were only observed at the very end of the seasonal drought period in the youngest stands.

Gas Hydrate Storage of Natural Gas  

SciTech Connect (OSTI)

Environmental and economic benefits could accrue from a safe, above-ground, natural-gas storage process allowing electric power plants to utilize natural gas for peak load demands; numerous other applications of a gas storage process exist. A laboratory study conducted in 1999 to determine the feasibility of a gas-hydrates storage process looked promising. The subsequent scale-up of the process was designed to preserve important features of the laboratory apparatus: (1) symmetry of hydrate accumulation, (2) favorable surface area to volume ratio, (3) heat exchanger surfaces serving as hydrate adsorption surfaces, (4) refrigeration system to remove heat liberated from bulk hydrate formation, (5) rapid hydrate formation in a non-stirred system, (6) hydrate self-packing, and (7) heat-exchanger/adsorption plates serving dual purposes to add or extract energy for hydrate formation or decomposition. The hydrate formation/storage/decomposition Proof-of-Concept (POC) pressure vessel and supporting equipment were designed, constructed, and tested. This final report details the design of the scaled POC gas-hydrate storage process, some comments on its fabrication and installation, checkout of the equipment, procedures for conducting the experimental tests, and the test results. The design, construction, and installation of the equipment were on budget target, as was the tests that were subsequently conducted. The budget proposed was met. The primary goal of storing 5000-scf of natural gas in the gas hydrates was exceeded in the final test, as 5289-scf of gas storage was achieved in 54.33 hours. After this 54.33-hour period, as pressure in the formation vessel declined, additional gas went into the hydrates until equilibrium pressure/temperature was reached, so that ultimately more than the 5289-scf storage was achieved. The time required to store the 5000-scf (48.1 hours of operating time) was longer than designed. The lower gas hydrate formation rate is attributed to a lower heat transfer rate in the internal heat exchanger than was designed. It is believed that the fins on the heat-exchanger tubes did not make proper contact with the tubes transporting the chilled glycol, and pairs of fins were too close for interior areas of fins to serve as hydrate collection sites. A correction of the fabrication fault in the heat exchanger fin attachments could be easily made to provide faster formation rates. The storage success with the POC process provides valuable information for making the process an economically viable process for safe, aboveground natural-gas storage.

Recovery of Water from Boiler Flue Gas  

SciTech Connect (OSTI)

This project dealt with use of condensing heat exchangers to recover water vapor from flue gas at coal-fired power plants. Pilot-scale heat transfer tests were performed to determine the relationship between flue gas moisture concentration, heat exchanger design and operating conditions, and water vapor condensation rate. The tests also determined the extent to which the condensation processes for water and acid vapors in flue gas can be made to occur separately in different heat transfer sections. The results showed flue gas water vapor condensed in the low temperature region of the heat exchanger system, with water capture efficiencies depending strongly on flue gas moisture content, cooling water inlet temperature, heat exchanger design and flue gas and cooling water flow rates. Sulfuric acid vapor condensed in both the high temperature and low temperature regions of the heat transfer apparatus, while hydrochloric and nitric acid vapors condensed with the water vapor in the low temperature region. Measurements made of flue gas mercury concentrations upstream and downstream of the heat exchangers showed a significant reduction in flue gas mercury concentration within the heat exchangers. A theoretical heat and mass transfer model was developed for predicting rates of heat transfer and water vapor condensation and comparisons were made with pilot scale measurements. Analyses were also carried out to estimate how much flue gas moisture it would be practical to recover from boiler flue gas and the magnitude of the heat rate improvements which could be made by recovering sensible and latent heat from flue gas.

Heat exchanger for coal gasification process  

DOE Patents [OSTI]

This invention provides a heat exchanger, particularly useful for systems requiring cooling of hot particulate solids, such as the separated fines from the product gas of a carbonaceous material gasification system. The invention allows effective cooling of a hot particulate in a particle stream (made up of hot particulate and a gas), using gravity as the motive source of the hot particulate. In a preferred form, the invention substitutes a tube structure for the single wall tube of a heat exchanger. The tube structure comprises a tube with a core disposed within, forming a cavity between the tube and the core, and vanes in the cavity which form a flow path through which the hot particulate falls. The outside of the tube is in contact with the cooling fluid of the heat exchanger.

Net?exchange analysis of the Earth greenhouse effect increase  

Science Journals Connector (OSTI)

In this paper we propose an analysis of the greenhouse effect on the basis of a net?exchange formulation for clear sky atmospheres. This formulation allows access to exchanges beetwen the differents elements of the atmosphere (gas layers the ground and space). When the greenhouse gas concentration increases we first use a simple configuration to analyse the variations of analytic monochromatic net exchange rates. The same type of analysis is then applied to the Earth atmosphere for a clear?sky middle latitude summer configuration with an increase in water vapour of 20% at all altitudes.

Heat exchanger for fuel cell power plant reformer  

DOE Patents [OSTI]

A heat exchanger uses the heat from processed fuel gas from a reformer for a fuel cell to superheat steam, to preheat raw fuel prior to entering the reformer and to heat a water-steam coolant mixture from the fuel cells. The processed fuel gas temperature is thus lowered to a level useful in the fuel cell reaction. The four temperature adjustments are accomplished in a single heat exchanger with only three heat transfer cores. The heat exchanger is preheated by circulating coolant and purge steam from the power section during startup of the latter.

Full optimized reaction space model for quantum chemical reaction calculations. Definition, applications, and the IntraAtomic correlation correction extension. [H/sub 2/ exchange between ethane and ethylene; gas-phase ozonolysis  

SciTech Connect (OSTI)

The Full Optimized Reaction Space (FORS) model is used for the theoretical calculation of molecular potential energy surfaces involved in chemical reactions. The FORS model is applied to two polyatomic reactions: the dihydrogen exchange between ethane and etylene, and the formation and dissolution of dioxirane and dioxymethane. The former reaction is found to possess a high barrier, in spite of its symmetry allowed nature. The latter reaction involves significant configuration mixing as methylene and oxygen react to form, successively, dioxirane, dioxymethane, and hydrogen and carbon dioxide. Finally, FORS wavefunctions can be expressed in terms of a basis of antisymmetrized products of atomic state functions, using the predominantly atomic projected localized orbitals. The atoms in molecules analysis permits the incorporation of data from atomic spectra into the molecular Hamiltonian to achieve the IntraAtomic Correlation Correction (IACC). The IACC scheme is illustrated for a few small diatomics (H/sub 2/, NH, F/sub 2/), and is shown to yield more accurate results than the uncorrected FORS wavefunctions.

Chemical exchange program analysis.  

SciTech Connect (OSTI)

As part of its EMS, Sandia performs an annual environmental aspects/impacts analysis. The purpose of this analysis is to identify the environmental aspects associated with Sandia's activities, products, and services and the potential environmental impacts associated with those aspects. Division and environmental programs established objectives and targets based on the environmental aspects associated with their operations. In 2007 the most significant aspect identified was Hazardous Materials (Use and Storage). The objective for Hazardous Materials (Use and Storage) was to improve chemical handling, storage, and on-site movement of hazardous materials. One of the targets supporting this objective was to develop an effective chemical exchange program, making a business case for it in FY07, and fully implementing a comprehensive chemical exchange program in FY08. A Chemical Exchange Program (CEP) team was formed to implement this target. The team consists of representatives from the Chemical Information System (CIS), Pollution Prevention (P2), the HWMF, Procurement and the Environmental Management System (EMS). The CEP Team performed benchmarking and conducted a life-cycle analysis of the current management of chemicals at SNL/NM and compared it to Chemical Exchange alternatives. Those alternatives are as follows: (1) Revive the 'Virtual' Chemical Exchange Program; (2) Re-implement a 'Physical' Chemical Exchange Program using a Chemical Information System; and (3) Transition to a Chemical Management Services System. The analysis and benchmarking study shows that the present management of chemicals at SNL/NM is significantly disjointed and a life-cycle or 'Cradle-to-Grave' approach to chemical management is needed. This approach must consider the purchasing and maintenance costs as well as the cost of ultimate disposal of the chemicals and materials. A chemical exchange is needed as a mechanism to re-apply chemicals on site. This will not only reduce the quantity of unneeded chemicals and the amount spent on new purchases, but will also avoid disposal costs. If SNL/NM were to realize a 5 percent reduction in chemical inventory and a 10 percent reduction in disposal of unused chemicals the total savings would be $189, 200 per year.

Microchannel Heat Exchangers with Carbon Dioxide  

SciTech Connect (OSTI)

The objective of the present study was to determine the performance of CO{sub 2} microchannel evaporators and gas coolers in operational conditions representing those of residential heat pumps. A set of breadboard prototype microchannel evaporators and gas coolers was developed and tested. The refrigerant in the heat exchangers followed a counter cross-flow path with respect to the airflow direction. The test conditions corresponded to the typical operating conditions of residential heat pumps. In addition, a second set of commercial microchannel evaporators and gas coolers was tested for a less comprehensive range of operating conditions. The test results were reduced and a comprehensive data analysis, including comparison with the previous studies in this field, was performed. Capacity and pressure drop of the evaporator and gas cooler for the range of parameters studied were analyzed and are documented in this report. A gas cooler performance prediction model based on non-dimensional parameters was also developed and results are discussed as well. In addition, in the present study, experiments were conducted to evaluate capacities and pressure drops for sub-critical CO{sub 2} flow boiling and transcritical CO{sub 2} gas cooling in microchannel heat exchangers. An extensive review of the literature failed to indicate any previous systematic study in this area, suggesting a lack of fundamental understanding of the phenomena and a lack of comprehensive data that would quantify the performance potential of CO{sub 2} microchannel heat exchangers for the application at hand. All experimental tests were successfully conducted with an energy balance within {+-}3%. The only exceptions to this were experiments at very low saturation temperatures (-23 C), where energy balances were as high as 10%. In the case of evaporators, it was found that a lower saturation temperature (especially when moisture condensation occurs) improves the overall heat transfer coefficient significantly. However, under such conditions, air side pressure drop also increases when moisture condensation occurs. An increase in airflow rate also increases the overall heat transfer coefficient. Air side pressure drop mainly depends on airflow rate. For the gas cooler, a significant portion of the heat transfer occurred in the first heat exchanger module on the refrigerant inlet side. The temperature and pressure of CO{sub 2} significantly affect the heat transfer and fluid flow characteristics due to some important properties (such as specific heat, density, and viscosity). In the transcritical region, performance of CO{sub 2} strongly depends on the operating temperature and pressure. Semi-empirical models were developed for predictions of CO{sub 2} evaporator and gas cooler system capacities. The evaporator model introduced two new factors to account for the effects of air-side moisture condensate and refrigerant outlet superheat. The model agreed with the experimental results within {+-}13%. The gas cooler model, based on non-dimensional parameters, successfully predicted the experimental results within {+-}20%. Recommendations for future work on this project include redesigning headers and/or introducing flow mixers to avoid flow mal-distribution problems, devising new defrosting techniques, and improving numerical models. These recommendations are described in more detail at the end of this report.

Recent development and application of several high-efficiency surface heat exchangers for energy conversion and utilization  

Science Journals Connector (OSTI)

Abstract In the present study, the recent research of three kinds of surface heat exchangers, i.e., shell-and-tube heat exchangers with helical baffles, air-cooled heat exchangers used in large air-cooled systems, and primary surface heat exchangers are reviewed. They are used in the energy conversion and utilization for liquid to liquid, gas to gas and liquid to gas heat exchange, respectively. It can be concluded that the helical baffled shell-and-tube heat exchangers (STHXs) should be used to replace the conventional segmental baffled \\{STHXs\\} in industries, despite there are a lot of research work have to be done, especially on the novel combined helical baffles. The primary surface gas to gas heat exchangers are developing towards to the more complex 3D CC primary surfaces, such as the double-wave CC primary surface, offset-bubble primary surface and 3D anti-phase secondary corrugation. The whole performance for the air-cooled heat exchangers in the air cooling system and the multi-objectives optimization for air-cooled heat exchangers should be paid more attention, considering the heat transfer, pumper power, space usage and other economic influence factors.

Exchange rate effect on carbon credit price via energy markets  

Science Journals Connector (OSTI)

Abstract This paper examines the impact of currency exchange rates on the carbon market. We scrutinize this effect through the European Union Emission Trading Scheme (EU-ETS), which primarily uses two substitutable fossil energy inputs for the generation of electricity: coal and natural gas. The European coal market is directly driven by global coal markets that are denominated in USD, whereas, natural gas is mainly imported from Russia and is denominated in Euros. The impulse response functions of a Structural Vector Autoregression (SVAR) model demonstrate†that a shock in the Euro/USD exchange rate can be transmitted through the channel of energy substitution between coal and natural gas, and influence on the carbon credit market.

On the week, the Henry Hub spot price increased 36 cents per MMBtu, or 5.7 percent, to $6.65. At the New York Mercantile Exchange (NYMEX), the story was slightly different with the contract price for August delivery decreasing to $6.600 per MMBtu, which was 1.8 cents lower than last Thursday's (July 5) closing price. EIA's Weekly Natural Gas Storage Report today reported natural gas storage supplies of 2,627 Bcf as of Friday, July 7. This level of working gas in underground storage is 16.6 percent above the 5-year average inventory for this time of year. The spot price for West Texas Intermediate (WTI) crude oil increased $0.77 per barrel on the week to $72.58 per barrel. On a Btu basis, the crude oil price is now nearly double the price of natural gas at $12.51 per MMBtu. The relative difference in pricing can have a large effect on demand (mostly in the industrial sector and power plants).

Easing prices also likely resulted in part from reduced supply uncertainty in response to the amount of natural gas in underground storage (mostly for use during the winter heating season but also available for periods of hot weather in the summer). Supplies from international sources have grown considerably this spring, as imports of liquefied natural gas (LNG) have increased markedly even as natural gas supplies from Canada (transported by pipeline) likely have decreased. On the week, the Henry Hub spot price decreased 23 cents per MMBtu, or 2.9 percent, to $7.60. At the New York Mercantile Exchange (NYMEX), the contract for July delivery decreased 47.2 cents per MMBtu on the week to a daily settlement of $7.608 yesterday (June 13). EIA's Weekly Natural Gas Storage Report today reported natural gas storage supplies of 2,255 Bcf as of Friday, June 8, reflecting an implied net injection of 92 Bcf. This level of working gas in underground storage is 19.3 percent above the 5-year average inventory for this time of year.

Next Release: Thursday, September 1, 2011 Overview Prices Storage Other Market Trends Overview (For the Week Ending Wednesday, August 24, 2011) Even an earthquake on Tuesday could not shake up most gas prices significantly for the week. However, the prospects of some near-term returning cooling load was likely the catalyst boosting overall cash market prices this week. The Henry Hub price increased 13 cents per million Btu (MMBtu) over the week (up 3.2 percent) to close at $4.10 per MMBtu on August 24. At the New York Mercantile Exchange (NYMEX), there was a 10.4 cent per MMBtu price spike on Tuesday following the East Coast earthquake but the September 2011 natural gas contract eventually gave most of the gain back and closed at $3.922 per MMBtu on Wednesday.

Heat exchanger for reactor core and the like  

DOE Patents [OSTI]

A compact bayonet tube type heat exchanger which finds particular application as an auxiliary heat exchanger for transfer of heat from a reactor gas coolant to a secondary fluid medium. The heat exchanger is supported within a vertical cavity in a reactor vessel intersected by a reactor coolant passage at its upper end and having a reactor coolant return duct spaced below the inlet passage. The heat exchanger includes a plurality of relatively short length bayonet type heat exchange tube assemblies adapted to pass a secondary fluid medium therethrough and supported by primary and secondary tube sheets which are releasibly supported in a manner to facilitate removal and inspection of the bayonet tube assemblies from an access area below the heat exchanger. Inner and outer shrouds extend circumferentially of the tube assemblies and cause the reactor coolant to flow downwardly internally of the shrouds over the tube bundle and exit through the lower end of the inner shroud for passage to the return duct in the reactor vessel.

2, 2007 (next release 2:00 p.m. on March 29, 2007) 2, 2007 (next release 2:00 p.m. on March 29, 2007) As the bitter cold has evolved to more moderate temperatures, natural gas spot prices have eased through most of the country. During the report week (Wednesday-Wednesday, March 14-21), the Henry Hub spot price declined 4 cents per MMBtu to $6.82. At the New York Mercantile Exchange (NYMEX), prices for futures contracts were slightly higher, as increases Tuesday and yesterday (March 20 and 21) more than offset decreases that occurred in the 3 previous trading days. The futures contract for April delivery, which is the first contract following the current heating season, increased 7.7 cents per MMBtu on the week to $7.160. Relatively high levels of natural gas in working storage and decreasing prices for competing fuels likely contributed to falling natural gas spot prices this week. Working gas in storage as of Friday, March 16, was 1,533 Bcf, which is 18.5 percent above the 5-year (2002-2006) average. The spot price for West Texas Intermediate (WTI) crude oil decreased $1.17 per barrel on the week to $56.98, or $9.82 per MMBtu.

MULTIPLE POLLUTANT REMOVAL USING THE CONDENSING HEAT EXCHANGER  

SciTech Connect (OSTI)

The Integrated Flue Gas Treatment (IFGT) system is a new concept whereby a Teflon ģ covered condensing heat exchanger is adapted to remove certain flue gas constituents, both particulate and gaseous, while recovering low level heat. The pollutant removal performance and durability of this device is the subject of a USDOE sponsored program to develop this technology. The program was conducted under contract to the United States Department of Energy?s Fossil Energy Technology Center (DOE-FETC) and was supported by the Ohio Coal Development Office (OCDO) within the Ohio Department of Development, the Electric Power Research Institute?s Environmental Control Technology Center (EPRI-ECTC) and Babcock and Wilcox - a McDermott Company (B&W). This report covers the results of the first phase of this program. This Phase I project has been a two year effort. Phase I includes two experimental tasks. One task dealt principally with the pollutant removal capabilities of the IFGT at a scale of about 1.2MWt. The other task studied the durability of the Teflon ģ covering to withstand the rigors of abrasive wear by fly ash emitted as a result of coal combustion. The pollutant removal characteristics of the IFGT system were measured over a wide range of operating conditions. The coals tested included high, medium and low-sulfur coals. The flue gas pollutants studied included ammonia, hydrogen chloride, hydrogen fluoride, particulate, sulfur dioxide, gas phase and particle phase mercury and gas phase and particle phase trace elements. The particulate removal efficiency and size distribution was investigated. These test results demonstrated that the IFGT system is an effective device for both acid gas absorption and fine particulate collection. Although soda ash was shown to be the most effective reagent for acid gas absorption, comparative cost analyses suggested that magnesium enhanced lime was the most promising avenue for future study. The durability of the Teflon ģ covered heat exchanger tubes was studied on a pilot-scale single- stage condensing heat exchanger (CHX ģ ). This device was operated under typical coal-fired flue gas conditions on a continuous basis for a period of approximately 10 months. Data from the test indicate that virtually no decrease in Teflon ģ thickness was observed for the coating on the first two rows of heat exchanger tubes, even at high inlet particulate loadings. Evidence of wear was present only at the microscopic level, and even then was very minor in severity.

7, 2007 (next release 2:00 p.m. on May 24, 2007) 7, 2007 (next release 2:00 p.m. on May 24, 2007) Natural gas spot and futures prices increased slightly this week (Wednesday-Wednesday, May 9-16), despite the usual lull in demand during this shoulder period between the winter heating and summer cooling seasons. The upward price trend likely resulted from a variety of factors, including rising prices for competing petroleum products (as evidenced by an increase in the underlying crude oil price). Additionally, concerns over current and future supplies do not appear to have eased. The official start of the hurricane season is imminent, and the first named tropical storm appeared this week. However, imports of liquefied natural gas (LNG) have increased markedly in the past few months. On the week, the Henry Hub spot price increased 16 cents per MMBtu, or 2 percent, to $7.62. At the New York Mercantile Exchange (NYMEX), the contract for June delivery increased 17.0 cents per MMBtu on the week to a daily settlement of $7.890 yesterday (May 16). EIA's Weekly Natural Gas Storage Report today reported natural gas storage supplies of 1,842 Bcf as of Friday, May 11, reflecting an implied net injection of 95 Bcf. This level of working gas in underground storage is 20.6 percent above the 5-year average inventory for this time of year. The spot price for West Texas Intermediate (WTI) crude oil increased $1.03 per barrel on the week to $62.57 per barrel, or $10.79 per MMBtu.

On the week, the Henry Hub spot price increased 62 cents per MMBtu, or 11.1 percent, to $6.19. At the New York Mercantile Exchange (NYMEX), the futures contract for August delivery expired last Friday (July 27) at $6.11 per MMBtu. Although the price of the expiring contract in the last couple days of trading rose slightly, the expiration price was still the second lowest of the year (the January 2007 contract expired at $5.838). Taking over as the near-month contract, the September 2007 contract increased in price by $0.29 per MMBtu on the week to $6.352. EIA's Weekly Natural Gas Storage Report today reported natural gas storage supplies of 2,840 Bcf as of Friday, July 27. This level of working gas in underground storage exceeds the maximum level of the previous 5 years. The spot price for West Texas Intermediate (WTI) crude oil increased $0.75 per barrel on the week to $76.49 per barrel. On a Btu basis, the crude oil price is now more than double the price of natural gas at $13.19 per MMBtu.

Small gas turbine technology  

Science Journals Connector (OSTI)

Small Gas Turbine Technology: Small gas turbine, in the power range up to 500 kW, requires a recuperated thermodynamic cycle to achieve an electrical efficiency of about 30%. This efficiency is the optimum, which is possible for a cycle pressure ratio of about 4Ė1. The cycle airflow is function of the power requirement. To increase the efficiency, in view to reduce the CO2 emission, it is mandatory to develop a more efficient thermodynamic cycle. Different thermodynamic cycles were examined and the final choice was made for an Intercooled, Recuperated cycle. The advantage of this cycle, for the same final electrical efficiency of about 35%, is the smaller cycle airflow, which is the most dimensional parameter for the important components as the heat exchanger recuperator and the combustion chamber. In parallel with the thermodynamic cycle it is necessary to develop the High Speed Alternator technology, integrated on the same shaft that the gas turbine rotating components, to achieve the constant efficiency at part loads, from 50% up to 100%, by the capacity to adjust the engine speed at the required load. To satisfy the stringent requirement in pollutant emissions of \\{NOx\\} and CO, the catalytic combustion system is the most efficient and this advance technology has to be proven. The major constraints for the small gas turbine technology development are the production cost and the maintenance cost of the unit. In the power range of 0Ė500 kW the gas turbine technology is in competition with small reciprocating engines, which are produced in large quantity for automotive industry, at a very low production cost.

Secondary Heat Exchanger Design and Comparison for Advanced High Temperature Reactor  

SciTech Connect (OSTI)

The goals of next generation nuclear reactors, such as the high temperature gas-cooled reactor and advance high temperature reactor (AHTR), are to increase energy efficiency in the production of electricity and provide high temperature heat for industrial processes. The efficient transfer of energy for industrial applications depends on the ability to incorporate effective heat exchangers between the nuclear heat transport system and the industrial process heat transport system. The need for efficiency, compactness, and safety challenge the boundaries of existing heat exchanger technology, giving rise to the following study. Various studies have been performed in attempts to update the secondary heat exchanger that is downstream of the primary heat exchanger, mostly because its performance is strongly tied to the ability to employ more efficient conversion cycles, such as the Rankine super critical and subcritical cycles. This study considers two different types of heat exchangersóhelical coiled heat exchanger and printed circuit heat exchangeróas possible options for the AHTR secondary heat exchangers with the following three different options: (1) A single heat exchanger transfers all the heat (3,400 MW(t)) from the intermediate heat transfer loop to the power conversion system or process plants; (2) Two heat exchangers share heat to transfer total heat of 3,400 MW(t) from the intermediate heat transfer loop to the power conversion system or process plants, each exchanger transfers 1,700 MW(t) with a parallel configuration; and (3) Three heat exchangers share heat to transfer total heat of 3,400 MW(t) from the intermediate heat transfer loop to the power conversion system or process plants. Each heat exchanger transfers 1,130 MW(t) with a parallel configuration. A preliminary cost comparison will be provided for all different cases along with challenges and recommendations.

Exchange and correlation as a functional of the local density of states  

Science Journals Connector (OSTI)

A functional Exc[?(r,?)] is presented, in which the exchange and correlation energy of an electron gas depends on the local density of occupied states. A simple local parametrization scheme is proposed, entirely from first-principles, based on the decomposition of the exchange-correlation hole in scattering states of different relative energies. In its practical Kohn-Sham-like form, the single-electron orbitals become the independent variables, and an explicit formula for the functional derivative is obtained.

A method of operating a vehicle including an engine, a transmission, an exhaust gas heat recovery (EGHR) heat exchanger, and an oil-to-water heat exchanger providing selective heat-exchange communication between the engine and transmission. The method includes controlling a two-way valve, which is configured to be set to one of an engine position and a transmission position. The engine position allows heat-exchange communication between the EGHR heat exchanger and the engine, but does not allow heat-exchange communication between the EGHR heat exchanger and the oil-to-water heat exchanger. The transmission position allows heat-exchange communication between the EGHR heat exchanger, the oil-to-water heat exchanger, and the engine. The method also includes monitoring an ambient air temperature and comparing the monitored ambient air temperature to a predetermined cold ambient temperature. If the monitored ambient air temperature is greater than the predetermined cold ambient temperature, the two-way valve is set to the transmission position.

Gas-cooled nuclear reactor  

DOE Patents [OSTI]

A gas-cooled nuclear reactor includes a central core located in the lower portion of a prestressed concrete reactor vessel. Primary coolant gas flows upward through the core and into four overlying heat-exchangers wherein stream is generated. During normal operation, the return flow of coolant is between the core and the vessel sidewall to a pair of motor-driven circulators located at about the bottom of the concrete pressure vessel. The circulators repressurize the gas coolant and return it back to the core through passageways in the underlying core structure. If during emergency conditions the primary circulators are no longer functioning, the decay heat is effectively removed from the core by means of natural convection circulation. The hot gas rising through the core exits the top of the shroud of the heat-exchangers and flows radially outward to the sidewall of the concrete pressure vessel. A metal liner covers the entire inside concrete surfaces of the concrete pressure vessel, and cooling tubes are welded to the exterior or concrete side of the metal liner. The gas coolant is in direct contact with the interior surface of the metal liner and transfers its heat through the metal liner to the liquid coolant flowing through the cooling tubes. The cooler gas is more dense and creates a downward convection flow in the region between the core and the sidewall until it reaches the bottom of the concrete pressure vessel when it flows radially inward and up into the core for another pass. Water is forced to flow through the cooling tubes to absorb heat from the core at a sufficient rate to remove enough of the decay heat created in the core to prevent overheating of the core or the vessel.

Multiple pollutant removal using the condensing heat exchanger. Task 3, Long term testing at the ECTC  

SciTech Connect (OSTI)

The objective of this task is to demonstrate long term operation of a condensing heat exchanger for coal-fired conditions. A small condensing heat exchanger will be installed at the Environmental Control Technology Center in Barker, New York. It will be installed downstream of the flue gas particulate removal system. The test will determine the amount of wear, if any, on the Teflon{trademark} covered internals of the heat exchanger. Visual inspection and measurements will be obtained for the Teflon{trademark} covered tubes during the test. The material wear study will conducted over a one year calendar period, and the CHX equipment will be operated to the fullest extent allowable.

Evaluation of fluid bed heat exchanger optimization parameters. Final report  

SciTech Connect (OSTI)

Uncertainty in the relationship of specific bed material properties to gas-side heat transfer in fluidized beds has inhibited the search for optimum bed materials and has led to over-conservative assumptions in the design of fluid bed heat exchangers. An experimental program was carried out to isolate the effects of particle density, thermal conductivity, and heat capacitance upon fluid bed heat transfer. A total of 31 tests were run with 18 different bed material loads on 12 material types; particle size variations were tested on several material types. The conceptual design of a fluidized bed evaporator unit was completed for a diesel exhaust heat recovery system. The evaporator heat transfer surface area was substantially reduced while the physical dimensions of the unit increased. Despite the overall increase in unit size, the overall cost was reduced. A study of relative economics associated with bed material selection was conducted. For the fluidized bed evaporator, it was found that zircon sand was the best choice among materials tested in this program, and that the selection of bed material substantially influences the overall system costs. The optimized fluid bed heat exchanger has an estimated cost 19% below a fin augmented tubular heat exchanger; 31% below a commercial design fluid bed heat exchanger; and 50% below a conventional plain tube heat exchanger. The comparisons being made for a 9.6 x 10/sup 6/ Btu/h waste heat boiler. The fluidized bed approach potentially has other advantages such as resistance to fouling. It is recommended that a study be conducted to develop a systematic selection of bed materials for fluidized bed heat exchanger applications, based upon findings of the study reported herein.

Phonon exchange in dilute Fermi-Bose mixtures: Tailoring the Fermi-Fermi interaction  

Science Journals Connector (OSTI)

We consider a mixture of a single-component Bose gas and a two-component Fermi gas at temperatures where the Bose gas is almost fully condensed. In such a mixture, two fermionic atoms can interact with each other by exchanging a phonon that propagates through the Bose condensate. We calculate the interaction potential due to this mechanism, and determine the effective s-wave scattering length for two fermions that interact, both directly by the interatomic potentials as well as by the above-mentioned exchange mechanism. We find that the effective scattering length is quite sensitive to changes in the condensate density, and becomes strongly energy dependent. In addition, we consider the mechanical stability of these mixtures, and also calculate the dispersion and the damping of the various collisionless collective modes of the gas.

On a cryogenic noble gas ion catcher  

E-Print Network [OSTI]

In-situ purification of the gas used as stopping medium in a noble gas ion catcher by operating the device at low temperatures of 60 to 150 K was investigated. Alpha-decay recoil ions from a 223Ra source served as energetic probes. The combined ion survival and transport efficiencies for 219Rn ions saturated below about 90 K, reaching 28.7(17) % in helium, 22.1(13) % in neon, and 17.0(10) % in argon. These values may well reflect the charge exchange and stripping cross sections during the slowing down of the ions, and thus represent a fundamental upper limit for the efficiency of noble gas ion catcher devices. We suggest the cryogenic noble gas ion catcher as a technically simpler alternative to the ultra-high purity noble gas ion catcher operating at room temperature.

Materials, Turbomachinery and Heat Exchangers for Supercritical CO2 Systems  

SciTech Connect (OSTI)

The objective of this project is to produce the necessary data to evaluate the performance of the supercritical carbon dioxide cycle. The activities include a study of materials compatibility of various alloys at high temperatures, the heat transfer and pressure drop in compact heat exchanger units, and turbomachinery issues, primarily leakage rates through dynamic seals. This experimental work will serve as a test bed for model development and design calculations, and will help define further tests necessary to develop high-efficiency power conversion cycles for use on a variety of reactor designs, including the sodium fast reactor (SFR) and very high-temperature gas reactor (VHTR). The research will be broken into three separate tasks. The first task deals with the analysis of materials related to the high-temperature S-CO{sub 2} Brayton cycle. The most taxing materials issues with regard to the cycle are associated with the high temperatures in the reactor side heat exchanger and in the high-temperature turbine. The system could experience pressures as high as 20MPa and temperatures as high as 650įC. The second task deals with optimization of the heat exchangers required by the S-CO{sub 2} cycle; the S-CO{sub 2} flow passages in these heat exchangers are required whether the cycle is coupled with a VHTR or an SFR. At least three heat exchangers will be required: the pre-cooler before compression, the recuperator, and the heat exchanger that interfaces with the reactor coolant. Each of these heat exchangers is unique and must be optimized separately. The most challenging heat exchanger is likely the pre-cooler, as there is only about a 40įC temperature change but it operates close to the CO{sub 2} critical point, therefore inducing substantial changes in properties. The proposed research will focus on this most challenging component. The third task examines seal leakage through various dynamic seal designs under the conditions expected in the S-CO{sub 2} cycle, including supercritical, choked, and two-phase flow conditions.

Natural Gas Weekly Update  

Gasoline and Diesel Fuel Update (EIA)

10, 2007 (next release 2:00 p.m. on May 17, 2007) 10, 2007 (next release 2:00 p.m. on May 17, 2007) Springtime temperatures in most regions of the country this week and lack of any significant cooling or heating load through much of the Lower 48 States led to an easing of natural gas spot prices since Wednesday, May 2. Furthermore, the formation of the first tropical storm of the 2007 Atlantic Hurricane Season 3 weeks prior to the beginning of the traditional hurricane season appeared to have no impact on the spot markets in the Lower 48 States. On the week (Wednesday-Wednesday, May 2-9), the Henry Hub spot price declined 18 cents per MMBtu, or 2.4 percent, to $7.46. In contrast to spot market activity, trading of futures contracts at the New York Mercantile Exchange (NYMEX) this week resulted in gains for all contracts with the exception of the near-month contract, possibly reflecting an expected tightness in supply over the summer months. While the NYMEX contract for June delivery decreased 1 cent per MMBtu on the week to a daily settlement of $7.720 yesterday (May 9), contracts through the end of the injection season all increased, albeit only by an average of 0.3 percent. Net injections reported in today's release of EIA's Weekly Natural Gas Storage Report brought natural gas storage supplies to 1,747 Bcf as of Friday, May 4, which is 20.5 percent above the 5-year average inventory for the report week. The spot price for West Texas Intermediate (WTI) crude oil decreased $2.24 per barrel on the week to $61.54 per barrel, or $10.61 per MMBtu.

Iodine Loading of NO Aged Silver Exchanged Mordenite  

SciTech Connect (OSTI)

In an off-gas treatment system for used nuclear fuel processing, a solid sorbent will typically be exposed to a gas stream for months at a time. This gas stream may be at elevated temperature and could contain water vapor, gaseous nitrogen oxides (NO{sub x}), nitric acid vapors, and a variety of other constituents. For this reason, it is important to evaluate the effects of long-term exposure, or aging, on proposed sorbents. Silver exchanged mordenite (AgZ) is being studied at Oak Ridge National Laboratory (ORNL) to determine its iodine sorption capacity after long term exposure to increasingly more complex chemical environments. Studies previously conducted at ORNL investigated the effects of aging reduced silver exchanged mordenite (Ag{sup 0}Z) in dry air, moist air, and NO2. This study investigated the effects of extended exposure to nitric oxide (NO) gas on the iodine capture performance of Ag{sup 0}Z. A deep bed of Ag{sup 0}Z was aged in a 1% nitric oxide (NO) air stream, and portions of the bed were removed at pre-determined intervals. After being removed from the NO stream, each sample was loaded with iodine in a thin bed configuration. These samples were analyzed by neutron activation analysis (NAA) to quantify the iodine content in the sample. Samples were removed at one week and one month. A 78% decrease in sample capacity was seen after one week of exposure, with no further decrease observed after 1 month of aging. The observed loss in capacity is larger in magnitude than previous studies exposing Ag{sup 0}Z to dry air, moist air, or NO2 gas. The aging study was terminated after one month and repeated; this successfully demonstrated the reproducibility of the results.

Modeling of temporal behavior of isotopic exchange between gaseous hydrogen and palladium hydride power  

SciTech Connect (OSTI)

A parametric rate-equation model is described which depicts the time dependent behavior of the isotopic exchange process occurring between the solid and gas phases in gaseous hydrogen (deuterium) flows through packed-powder palladium deuteride (hydride) beds. The exchange mechanism is assumed to be rate-limited by processes taking place on the surface of the powder. The fundamental kinetic parameter of the model is the isotopic exchange probability, p, which is the probability that an isotopic exchange event occurs during a collision of a gas phase atom with the surface. Isotope effects between the gas and solid phases are explicitly included in terms of the isotope separation factor, ..cap alpha... Results of the model are compared with recent experimental measurements of isotope exchange in the ..beta..-phase hydrogen/palladium system and, using a literature value of ..cap alpha.. = 2.4, a good description of the experimental data is obtained for p approx. 10/sup -7/. In view of the importance of the isotope effects in the hydrogen/palladium system and the range of ..cap alpha.. values reported for the ..beta..-phase in the literature, the sensitivity of the model results to a variation in the value of ..cap alpha.. is examined.

Gas sensor  

DOE Patents [OSTI]

A gas sensor is described which incorporates a sensor stack comprising a first film layer of a ferromagnetic material, a spacer layer, and a second film layer of the ferromagnetic material. The first film layer is fabricated so that it exhibits a dependence of its magnetic anisotropy direction on the presence of a gas, That is, the orientation of the easy axis of magnetization will flip from out-of-plane to in-plane when the gas to be detected is present in sufficient concentration. By monitoring the change in resistance of the sensor stack when the orientation of the first layer's magnetization changes, and correlating that change with temperature one can determine both the identity and relative concentration of the detected gas. In one embodiment the stack sensor comprises a top ferromagnetic layer two mono layers thick of cobalt deposited upon a spacer layer of ruthenium, which in turn has a second layer of cobalt disposed on its other side, this second cobalt layer in contact with a programmable heater chip.

Assimilation of satellite reflecance dataa into a dynamical leaf model to infer seasonally varying leaf area for climate and carbon models  

SciTech Connect (OSTI)

Leaf area index is an important input for many climate and carbon models. The widely used leaf area products derived from satellite-observed surface reflectances contain substantial erratic fluctuations in time due to inadequate atmospheric corrections and observational and retrieval uncertainties. These fluctuations are inconsistent with the seasonal dynamics of leaf area, known to be gradual. Their use in process-based terrestrial carbon models corrupts model behavior, making diagnosis of model performance difficult. We propose a data assimilation approach that combines the satellite observations of Moderate Resolution Imaging Spectroradiometer (MODIS) albedo with a dynamical leaf model. Its novelty is that the seasonal cycle of the directly retrieved leaf areas is smooth and consistent with both observations and current understandings of processes controlling leaf area dynamics. The approach optimizes the dynamical model parameters such that the difference between the estimated surface reflectances based on the modeled leaf area and those of satellite observations is minimized. We demonstrate the usefulness and advantage of our new approach at multiple deciduous forest sites in the United States.

Prices in Lower 48 market areas in the West and the Midcontinent decreased significantly on the week. Other regions, however, most notably the high-demand areas of the Northeast and the Midwest, as well as Gulf Coast production areas, recorded price increases. The spot price at the Henry Hub gained 16 cents per MMBtu, or about 2 percent, to $7.42 per MMBtu. In contrast to the spot market, prices of futures contracts at the New York Mercantile Exchange (NYMEX) for the next 12 months uniformly decreased, with the futures contract for December delivery at the Henry Hub decreasing about 71 cents since last Wednesday to close yesterday (November 7) at $7.624 per MMBtu. Working gas stocks as of Friday, November 2, again hit a record high with 3,545 Bcf in storage, which is 8.9 percent above the 5-year average. The spot price for West Texas Intermediate (WTI) crude oil increased $2.30 per barrel, or 2.4 percent, since last Wednesday to trade yesterday at $96.46 per barrel or $16.63 per MMBtu.

Ion exchange purification of scandium  

DOE Patents [OSTI]

An improvement in purification of scandium through ion exchange chromatography is disclosed in which the oxidation potential of the eluting solution is altered by the addition of potassium chlorate or ammonium chloride so that removal of contaminants is encouraged. The temperature, pH and concentration of the eluent HEDTA are controlled in order to maintain the scandium in the column while minimizing dilution of the scandium band. Recovery of scandium is improved by pumping dilute scandium over the column prior to stripping the scandium and precipitation. This eliminates the HEDTA ion and other monovalent cations contaminating the scandium band. This method maximizes recovery of scandium while maintaining purity. 2 figs.

Gas Feedback on Stellar Bar Evolution  

E-Print Network [OSTI]

We analyze evolution of live disk-halo systems in the presence of various gas fractions, f_gas less than 8% in the disk. We addressed the issue of angular momentum (J) transfer from the gas to the bar and its effect on the bar evolution. We find that the weakening of the bar, reported in the literature, is not related to the J-exchange with the gas, but is caused by the vertical buckling instability in the gas-poor disks and by a steep heating of a stellar velocity dispersion by the central mass concentration (CMC) in the gas-rich disks. The gas has a profound effect on the onset of the buckling -- larger f_gas brings it forth due to the more massive CMCs. The former process leads to the well-known formation of the peanut-shaped bulges, while the latter results in the formation of progressively more elliptical bulges, for larger f_gas. The subsequent (secular) evolution of the bar differs -- the gas-poor models exhibit a growing bar while gas-rich models show a declining bar whose vertical swelling is driven by a secular resonance heating. The border line between the gas-poor and -rich models lies at f_gas ~ 3% in our models, but is model-dependent and will be affected by additional processes, like star formation and feedback from stellar evolution. The overall effect of the gas on the evolution of the bar is not in a direct J transfer to the stars, but in the loss of J by the gas and its influx to the center that increases the CMC. The more massive CMC damps the vertical buckling instability and depopulates orbits responsible for the appearance of peanut-shaped bulges. The action of resonant and non-resonant processes in gas-poor and gas-rich disks leads to a converging evolution in the vertical extent of the bar and its stellar dispersion velocities, and to a diverging evolution in the bulge properties.

31 (next release 2:00 p.m. on April 7) 31 (next release 2:00 p.m. on April 7) With the traditional heating season coming to a close, temperatures moderated this week and spot price changes were relatively small at most trading locations. For the week (Wednesday-Wednesday, March 23-30), the spot price at the Henry Hub increased 6 cents per MMBtu, or less than 1 percent to $7.17. In contrast to the mixed price patterns on the spot markets, the prices of futures contracts at the New York Mercantile Exchange (NYMEX) for delivery through next heating season all rose on the week. After rising 32.4 cents per MMBtu on Tuesday, March 29, the day of expiration, the April NYMEX contract's monthly settlement price was $7.323. The futures contract for May delivery at the Henry Hub yesterday (Wednesday, March 30) settled at $7.460 per MMBtu, which is 20.5 cents more than last Wednesday's price. Natural gas in storage decreased to 1,239 Bcf as of March 25, which is 19.9 percent above the 5-year average. The spot price for West Texas Intermediate (WTI) crude oil fell $4.53 per barrel or about 9 percent since last Wednesday to $53.96 per barrel or $9.30 per MMBtu.

9, 2004 (next release 2:00 p.m. on February 5) 9, 2004 (next release 2:00 p.m. on February 5) Spot prices in most regional markets ended the week (Wednesday-Wednesday, January 21-28) lower, despite severe cold in the Northeast beginning Friday (January 23) and continuing through the weekend. As a result, prices in the Northeast market proved the major exception to the downward trend, as cash prices moved up sharply at most locations in the region. At the Henry Hub, the spot price was 23 cents per MMBtu lower on the week, or about 4 percent, ending with yesterday's (Wednesday, January 28) level of $6.04. At the New York Mercantile Exchange (NYMEX), the futures contract for February delivery showed a modest gain of nearly 6 cents on its final day of trading, closing out at $5.775 per MMBtu. The contract for March delivery assumes the near-month position beginning today (Thursday, January 29). The Energy Information Administration (EIA) reported that natural gas inventories were 2,063 Bcf as of Friday, January 23, which is 8.6 percent greater than the previous 5-year (1999-2003) average. West Texas Intermediate crude oil on the spot market fell $1.90 per barrel, or $0.26 per MMBtu, since last Wednesday (January 21), ending trading yesterday at $33.63 per barrel, or $5.80 per MMBtu.

Influence of continuous and discontinuous supplemental lighting on the daily variation in gaseous exchange in greenhouse cucumber  

Science Journals Connector (OSTI)

Stomatal conductance, transpiration, net photosynthesis and internal CO2 concentration were measured on the fifth leaf of 36- to 43-day-old cucumber (Cucumis sativus L.) plants. Three series of measurements followed the variations during a diurnal period in gaseous exchange of plants under three light regimes. One group of plants received supplemental lighting split into two periods (04:00Ė08:00 and 16:00Ė22:00) for a continuous 18-h photoperiod. A second group was illuminated between 19:00 and 05:00 for a discontinuous 18-h photoperiod. The last group received only natural light (control). Supplemental lighting increased the stomatal conductance and transpiration. Extending the photoperiod with supplemental lighting increased the net photosynthesis rate and extended the period of CO2 assimilation. The internal CO2 concentration varied inversely with the CO2 assimilation rate. The continuity or discontinuity of the photoperiod did not affect gaseous exchange.

DHE (downhole heat exchangers). [Downhole Heat Exchangers (DHE)  

SciTech Connect (OSTI)

The use of downhole heat exchangers (DHE) for residential or commercial space and domestic water heating and other applications has several desirable features. Systems are nearly or completely passive -- that is, no or very little geothermal water or steam is produced from the well either reducing or completely eliminating surface environmental concerns and the need for disposal systems or injection wells. Initial cost of pumps and installation are eliminated or reduced along with pumping power costs and maintenance costs associated with pumping often corrosive geothermal fluids. Many residential and small commercial systems do not require circulating pumps because the density difference in the incoming and outgoing sides of the loop are sufficient to overcome circulating friction losses in the entire system. The major disadvantage of DHEs is their dependence on natural heat flow. In areas where geological conditions provide high permeability and a natural hydraulic gradient, DHEs can provide a substantial quantity of heat. A single 500-ft (152 m) well in Klamath Falls, Oregon, supplies over one megawatt thermal and output is apparently limited by the surface area of pipe that can be installed in the well bore. In contrast, DHEs used in conjunction with heat pumps may supply less than 8 KW from a well of similar depth. Here output is limited by conductive heat flow with perhaps a small contribution from convection near the well bore. The highest capacity DHE reported to date, in Turkey, supplies 6 MW thermal from an 820-ft (250 m) well. There were two main goals for this project. The first was to gather, disseminate and exchange internationally information on DHES. The second was to perform experiments that would provide insight into well bore/aquifer interaction and thereby provide more information on which to base DHE designs. 27 refs., 31 figs., 3 tabs.

Exchange Fluctuation Theorem for correlated quantum systems  

E-Print Network [OSTI]

We extend the Exchange Fluctuation Theorem for energy exchange between thermal quantum systems beyond the assumption of molecular chaos, and describe the non-equilibrium exchange dynamics of correlated quantum states. The relation quantifies how the tendency for systems to equilibrate is modified in high-correlation environments. Our results elucidate the role of measurement disturbance for such scenarios. We show a simple application by finding a semi-classical maximum work theorem in the presence of correlations.

Nitrogen Removal From Low Quality Natural Gas  

SciTech Connect (OSTI)

Natural gas provides more than one-fifth of all the primary energy used in the United States. It is especially important in the residential sector, where it supplies nearly half of all the energy consumed in U.S. homes. However, significant quantities of natural gas cannot be produced economically because its quality is too low to enter the pipeline transportation system without some type of processing, other than dehydration, to remove the undesired gas fraction. Such low-quality natural gas (LQNG) contains significant concentration or quantities of gas other than methane. These non- hydrocarbons are predominantly nitrogen, carbon dioxide, and hydrogen sulfide, but may also include other gaseous components. The nitrogen concentrations usually exceeds 4%. Nitrogen rejection is presently an expensive operation which can present uneconomic scenarios in the potential development of natural gas fields containing high nitrogen concentrations. The most reliable and widely used process for nitrogen rejection from natural gas consists of liquefying the feed stream using temperatures in the order of - 300{degrees}F and separating the nitrogen via fractionation. In order to reduce the gas temperature to this level, the gas is compressed, cooled by mullet-stream heat exchangers, and expanded to low pressure. Significant energy for compression and expensive materials of construction are required. Water and carbon dioxide concentrations must be reduced to levels required to prevent freezing. SRI`s proposed research involves screening new nitrogen selective absorbents and developing a more cost effective nitrogen removal process from natural gas using those compounds. The long-term objective of this project is to determine the technical and economical feasibility of a N{sub 2}2 removal concept based on complexation of molecular N{sub 2} with novel complexing agents. Successful development of a selective, reversible, and stable reagent with an appropriate combination of capacity and N{sub 2} absorption/desorption characteristics will allow selective separation of N{sub 2} from LQNG.

SoilĖplant nitrogen cycling modulated carbon exchanges in a western temperate conifer forest in Canada  

Science Journals Connector (OSTI)

Nitrogen controls, on the seasonal and inter-annual variability of net ecosystem productivity (NEP) in a western temperate conifer forest in British Columbia, Canada, were simulated by a coupled carbon and nitrogen (C&N) model. The model was developed by incorporating plantĖsoil nitrogen algorithms in the Carbon-Canadian Land Surface Scheme (C-CLASS). In the coupled C&N-CLASS, the maximum carboxylation rate of Rubisco (Vcmax) is determined non-linearly from the modelled leaf Rubisco-nitrogen, rather than being prescribed. Hence, variations in canopy assimilation and stomatal conductance are sensitive to leaf nitrogen status through the Rubisco enzyme. The plantĖsoil nitrogen cycle includes nitrogen pools from photosynthetic enzymes, leaves and roots, as well as organic and mineral reservoirs from soil, which are generated, exchanged, and lost by biological fixation, atmospheric deposition, fertilization, mineralization, nitrification, root uptake, denitrification, and leaching. Model output was compared with eddy covariance flux measurements made over a 5-year period (1998Ė2002). The model performed very well in simulating half-hourly and monthly mean NEP values for a range of environmental conditions observed during the 5 years. C&N-CLASS simulated NEP values were 274, 437, 354, 352 and 253†g†C†m?2 for 1998Ė2002, compared to observed NEP values of 269, 360, 381, 418 and 264†g†C†m?2, for the respective years. Compared to the default C-CLASS, the coupled C&N model showed improvements in simulating the seasonal and annual dynamics of carbon fluxes in this forest. The nitrogen transformation to soil organic forms, mineralization, plant nitrogen uptake and leaf Rubisco-nitrogen concentration patterns were strongly influenced by seasonal and annual temperature variations. In contrast, the impact of precipitation was insignificant on the overall forest nitrogen budget. The coupled C&N modelling framework will help to evaluate the impact of nitrogen cycle on terrestrial ecosystems and its feedbacks on Earth's climate system.

Effect of Channel Configurations for Tritium Transfer in Printed Circuit Heat Exchangers  

SciTech Connect (OSTI)

The Next Generation Nuclear Plant (NGNP), a very High temperature Gas-Cooled Reactor (VHTR) concept, will provide the first demonstration of a closed-loop Brayton cycle at a commercial scale of a few hundred megawatts electric and hydrogen production. The power conversion system (PCS) for the NGNP will take advantage of the significantly higher reactor outlet temperatures of the VHTR to provide higher efficiencies than can be achieved in the current generation of light water reactors. Besides demonstrating a system design that can be used directly for subsequent commercial deployment, the NGNP will demonstrate key technology elements that can be used in subsequent advanced power conversion systems for other Generation IV reactors. In anticipation of the design, development and procurement of an advanced power conversion system for the NGNP, the system integration of the NGNP and hydrogen plant was initiated to identify the important design and technology options that must be considered in evaluating the performance of the proposed NGNP. In the VHTR system, an intermediate heat exchanger (IHX), which transfers heat from the reactor core to the electricity or hydrogen production system is one key component, and its effectiveness is directly related to the system overall efficiency. In the VHTRs, the gas fluids used for coolant generally have poor heat transfer capability, so it requires very large surface area for a given condition. For this reason, a compact heat exchanger (CHE), which is widely used in industry especially for gasto-gas or gas-to-liquid heat exchange is considered as a potential candidate for an IHX replacing the classical shell and tube type heat exchanger. A compact heat exchanger is arbitrary referred to be a heat exchanger having a surface area density greater than 700 m2/m3. The compactness is usually achieved by fins and micro-channels, and leads to the enormous heat transfer enhancement and size reduction. The surface area density is the total heat transfer area divided by the volume of the heat exchanger. In the case of PCHE units, the heat transfer surface area density may be as high as 2,500 m2/m3. This high compactness implies an appreciable reduction in material reducing cost. In this study, heat transfer and tritium penetration analyses have been performed for two different channel configurations of the PCHE; (1) standard and (2) off-set. One of the goals of this study was to determine whether offsetting the hot and cold streams would significantly reduce the tritium flux, and whether or not it would affect the heat transfer significantly.

Long-term corrosion measurements in condensing heat exchangers. Topical report, September 1989-January 1993  

SciTech Connect (OSTI)

Corrosion of metals used in condensing heat exchangers for gas appliances has been correlated most strongly with the chloride content of the condensate. This study presents results of an experimental examination of the long-term corrosion in metals used in condensing heat exchangers. The objective of this work is to develop a rationale for predicting the performance and expected service life of metals in condensing heat exchangers. Long-term exposure tests were conducted using finned-tube condensing heat exchangers containing tubes of 304L, 3161L, 3171L, Sea-Cure, and 29-4C steel, and aluminum. The natural gas was spiked with R-11 to generate chloride ion levels in the condensate of 3 ppm, 26 ppm, and 225 ppm. The aluminum tubes experienced through-the-wall pitting after 1.5 months at 225 ppm chloride, and after 6 months at 26 ppm chloride. At 3 ppm, most of the tubes exhibited no corrosion. At 225 ppm and 26 ppm, the 300-series stainless steels experienced through-the-wall corrosion within 3 months, but at 3 ppm virtually no corrosion was found. Sea-Cure and 29-4C exhibited the best corrosion resistance with some pitting at 225 ppm but none at 26 ppm and 3 ppm.
