Cracking of simulated oil refinery off-gas over a coal char, petroleum coke, and quartz  

SciTech Connect (OSTI)

The cracking of oil refinery off-gas, simulated with a gas mixture containing methane (51%), ethylene (21.4%), ethane (21.1%), and propane (6.5%), over a coal char, petroleum coke, and quartz, respectively, has been studied in a fixed bed reactor. The experiments were performed at temperatures between 850 and 1000{sup o}C and at atmospheric pressure. The results show that the conversions of all species considered increased with increasing temperature. Ethane and propane completely decomposed over all three bed materials in the temperature range investigated. However, the higher initial conversion rates of methane and ethylene cracking at all temperatures were observed only over the coal char and not on the petroleum coke and quartz, indicating a significant catalytic effect of the coal char on methane and ethylene cracking. Methane and ethylene conversions decreased with reaction time due to deactivation of the coal char by carbon deposition on the char surface and, in the later stage of a cracking experiment, became negative, suggesting that methane and ethylene had been formed during the cracking of ethane and propane. 16 refs., 13 figs., 2 tabs.

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Propane: Liquefied Petroleum Gas (LPG) Propane: Liquefied Petroleum Gas (LPG) Ford F-150 (Dual-Fuel LPG) Propane or liquefied petroleum gas (LPG) is a clean-burning fossil fuel that can be used to power internal combustion engines. LPG-fueled vehicles can produce significantly lower amounts of some harmful emissions and the greenhouse gas carbon dioxide (CO2). LPG is usually less expensive than gasoline, it can be used without degrading vehicle performance, and most LPG used in U.S. comes from domestic sources. The availability of LPG-fueled light-duty passenger vehicles is currently limited. A few light-duty vehicles-mostly larger trucks and vans-can be ordered from a dealer with a prep-ready engine package and converted to use propane. Existing conventional vehicles can also be converted for LPG use.

Liquefaction of coal in a petroleum fraction under mild conditions  

Science Journals Connector (OSTI)

Experimental studies on a mild coal liquefaction process for extending the petroleum fuel supply are presented. In this process, coal is dissolved in bottoms from fluid catalytic cracking (FCC), a thermally stable, highly aromatic refinery stream, without added hydrogen and under mild conditions. After ash removal, the product mixture of coal liquid and FCC bottoms is a pumpable fluid and can be used as a boiler fuel. Further upgrading to turbine fuel may be possible. At 600–800°F, 0.1 to 5 h, and 0–1000 psig, conversion of a bituminous coal to pyridine soluble, gas and water was about 90%, while that of lignite was about 60%. Improved product quality was favored by increased reaction pressure. The operable solvent to coal ratio can be as low as 1.3. This ratio can be further reduced if provisions are made to recycle part of the solvent. However, the efficiency of the recovered solvent decreases with each recycle due to a gradual replacement of labile ? hydrogen by ? hydrogen.

Coal Beneficiation by Gas Agglomeration  

SciTech Connect (OSTI)

Coal beneficiation is achieved by suspending coal fines in a colloidal suspension of microscopic gas bubbles in water under atmospheric conditions to form small agglomerates of the fines adhered by the gas bubbles. The agglomerates are separated, recovered and resuspended in water. Thereafter, the pressure on the suspension is increased above atmospheric to deagglomerate, since the gas bubbles are then re-dissolved in the water. During the deagglomeration step, the mineral matter is dispersed, and when the pressure is released, the coal portion of the deagglomerated gas-saturated water mixture reagglomerates, with the small bubbles now coming out of the solution. The reagglomerate can then be separated to provide purified coal fines without the mineral matter.

Effect of petroleum coke addition on coal gasification  

Science Journals Connector (OSTI)

The main fuel for power generation is combustion of coal and/or natural gas. Natural gas is expensive but clean and less problematic whereas coal is the reverse of natural gas. Natural gas resources are expected to last until 2020 where else coal has another 200 years expectancy. To replace the natural gas synthetic gas (syngas) can be used as a substitute fuel. Syngas can be produced using coal as fuel. In this study we blend petcoke a cheap solid carboneous fuel as an alternative to coal for the production of syngas using a 30 Kwattheat bubbling fluidized bed gasifier. The equivalent ratio (ER) was set at 2.8 and a gasification temperature was maintained between 680 to 710°C by manipulating between the feed flow rates and fluidizing medium. This condition was chosen as it proved to be the optimum based on the work by the same group. Various blend of coal:petcoke between 0 to 100% was analyzed. It was found that a 20:80 petcoke to coal gives a good correlation with 100% coal gasification.

Structural group composition and thermodynamic properties of petroleum and coal tar fractions  

SciTech Connect (OSTI)

The improved G-L method was developed for determining the structural group composition of petroleum and coal tar fractions by using experimental values of refraction index, density, molecular weight, and S, N, O, and olefinic group content. The method is useful for fractions boiling in the range 30--500 C containing S, N, O and in total up to 10%, not limiting the distribution of the carbon atoms between aromatic, naphthenic, and paraffinic structures. Several correlations are proposed for prediction of the thermodynamic properties of petroleum and coal tar fractions, i.e., molar volume; surface tension; heat capacity in gas, liquid, and solid phases as a function of temperature; and also critical properties standard heat and entropy of formation, and temperature and entropy of melting. The method and these correlations have been tested on hydrocarbons and other organic compounds with satisfactory accuracy.

Chapter 10 - Coal and Coalbed Gas: Outlook  

Science Journals Connector (OSTI)

Abstract The future of coal and coalbed gas future is intertwined as source and reservoir rocks. Coal generates coalbed gas during coalification (e.g. thermogenic gas) and methanogenesis (biogenic gas). These gas types occur as singular and mixed accumulations. Accumulation of biogenic coalbed gas has received worldwide research and development interests on sustaining production. The new coal-to-biogenic coalbed gas technology centers on stimulating indigenous microbes in coal and associated groundwater with bioengineered nutrients and amendments to “farm” gas from abandoned wells and non-gas-producing coals. Coal mainly as a basic fuel for electric power generation since the Industrial Revolution continues to be utilized despite environmental concerns. The outlook of coal is dimmed in the United States where natural gas has replaced power generation. However, in Asia and Europe continued economic growth is going to be fueled by coal and coalbed gas as liquefied natural gas will rely on combustion from more efficient, high-temperature power plants in the future.

Jute fiber composites from coal, super clean coal, and petroleum vacuum residue-modified phenolic resin  

SciTech Connect (OSTI)

Jute fiber composites were prepared with novolac and coal, phenolated-oxidized super clean coal (POS), petroleum vacuum residue (XVR)-modified phenol-formaldehyde (novolac) resin. Five different type of resins, i.e., coal, POS, and XVR-modified resins were used by replacing (10% to 50%) with coal, POS, and XVR. The composites thus prepared have been characterized by tensile strength, hardness, thermogravimetric analysis (TGA), Fourier-transfer infrared (FT-IR), water absorption, steam absorption, and thickness swelling studies. Twenty percent POS-modified novolac composites showed almost the same tensile strength as that of pure novolac composites. After 30% POS incorporation, the tensile strength decreased to 25.84MPa from 33.96MPa in the case of pure novolac resin composites. However, after 50% POS incorporation, the percent retention of tensile strength was appreciable, i.e., 50.80% retention of tensile strength to that of pure novolac jute composites. The tensile strength of coal and XVR-rnodified composites showed a trend similar to that shown by POS-modified novolac resin composites. However, composites prepared from coal and XVR-modified resin with 50% phenol replacement showed 25.4% and 42% tensile strength retention, respectively, compared to that of pure novolac jute composites. It was found that the hardness of the modified composites slightly decreased with an increase in coal, POS, and XVR incorporation in the resin. The XVR-modified composites showed comparatively lower steam absorption than did coal or POS-modified composites. The thermal stability of the POS-modified composites was the highest among the composites studied. The detailed results obtained are being reported.

Advanced coal-fueled gas turbine systems  

SciTech Connect (OSTI)

Several technology advances since the early coal-fueled turbine programs that address technical issues of coal as a turbine fuel have been developed in the early 1980s: Coal-water suspensions as fuel form, improved methods for removing ash and contaminants from coal, staged combustion for reducing NO{sub x} emissions from fuel-bound nitrogen, and greater understanding of deposition/erosion/corrosion and their control. Several Advanced Coal-Fueled Gas Turbine Systems programs were awarded to gas turbine manufacturers for for components development and proof of concept tests; one of these was Allison. Tests were conducted in a subscale coal combustion facility and a full-scale facility operating a coal combustor sized to the Allison Model 501-K industrial turbine. A rich-quench-lean (RQL), low nitrogen oxide combustor design incorporating hot gas cleanup was developed for coal fuels; this should also be applicable to biomass, etc. The combustor tests showed NO{sub x} and CO emissions {le} levels for turbines operating with natural gas. Water washing of vanes from the turbine removed the deposits. Systems and economic evaluations identified two possible applications for RQL turbines: Cogeneration plants based on Allison 501-K turbine (output 3.7 MW(e), 23,000 lbs/hr steam) and combined cycle power plants based on 50 MW or larger gas turbines. Coal-fueled cogeneration plant configurations were defined and evaluated for site specific factors. A coal-fueled turbine combined cycle plant design was identified which is simple, compact, and results in lower capital cost, with comparable efficiency and low emissions relative to other coal technologies (gasification, advanced PFBC).

Chapter 9 - Gas Outbursts in Coal Seams  

Science Journals Connector (OSTI)

Abstract Gas outbursts are sudden, violent blowouts of coal and gas from the solid coal seam into a mine entry. These dangerous incidents have occurred in most coal producing countries, although they have been relatively rare in the U.S., probably due to better mining conditions. Factors affecting the likelihood of a gas outburst are the gassiness and depth of the seam, stress fields in the rock mass, characteristics of the coal such as the permeability, the rate of mining advance, and local geologic structures like faults or clay veins. The most probable location for an outburst is at the working face where the gas pressure gradient, the main driving force, is steepest. Draining gas through boreholes drilled into the seam helps to prevent gas outbursts. This report will highlight the conditions that make a gas outburst likely and the methods used to reduce the chance of an outburst. It will also examine the differences between gas outbursts and coal mine bumps (also called bursts), which are the far more common stress-failure mode in U.S. coal mines.

16, 2008 16, 2008 Innovative Coal-Based Product Bumps Petroleum Out of Equation Synthetic Binder Pitch Uses Hydrocarbons from Coal in Place of Petroleum Feedstocks WASHINGTON, DC - Through a cooperative agreement with the Office of Fossil Energy's National Energy Technology Laboratory (NETL), a team headed by West Virginia University (WVU) has developed and successfully demonstrated a synthetic binder pitch that uses hydrocarbons from coal to supplement or replace petroleum feedstocks. The new binder pitch, and similar coal-derived products, could potentially reduce America's dependence on imported oil. Binder pitch - a carbon-rich, tar-like material - is an important ingredient in making graphite rods used in electric arc furnaces for the manufacture of steel from scrap. Conventional binder pitch usually blends petroleum pitch with standard coal-tar pitch. The new synthetic pitch could replace at least 19,000 tons of conventional pitch needed each year by graphite electrode manufacturers. WVU claims that the same pitch could be used by the aluminum industry; if so, demand for the new product would be close to one million barrels per year.

Comparative analysis of the production costs and life-cycle GHG emissions of FT liquid fuels from coal and natural gas  

SciTech Connect (OSTI)

Liquid transportation fuels derived from coal and natural gas could help the United States reduce its dependence on petroleum. The fuels could be produced domestically or imported from fossil fuel-rich countries. The goal of this paper is to determine the life-cycle GHG emissions of coal- and natural gas-based Fischer-Tropsch (FT) liquids, as well as to compare production costs. The results show that the use of coal- or natural gas-based FT liquids will likely lead to significant increases in greenhouse gas (GHG) emissions compared to petroleum-based fuels. In a best-case scenario, coal- or natural gas-based FT-liquids have emissions only comparable to petroleum-based fuels. In addition, the economic advantages of gas-to-liquid (GTL) fuels are not obvious: there is a narrow range of petroleum and natural gas prices at which GTL fuels would be competitive with petroleum-based fuels. CTL fuels are generally cheaper than petroleum-based fuels. However, recent reports suggest there is uncertainty about the availability of economically viable coal resources in the United States. If the U.S. has a goal of increasing its energy security, and at the same time significantly reducing its GHG emissions, neither CTL nor GTL consumption seem a reasonable path to follow. 28 refs., 2 figs., 4 tabs.

Thermal-destruction products of coal in the blast-furnace gas-purification system  

SciTech Connect (OSTI)

The lean, poorly clinkering coal and anthracite used to replace coke in blast furnaces has a considerable content of volatile components (low-molecular thermaldestruction products), which enter the water and sludge of the blast-furnace gas-purification system as petroleum products. Therefore, it is important to study the influence of coal on the petroleum-product content in the water and sludge within this system. The liberation of primary thermal-destruction products is investigated for anthracite with around 4 wt % volatiles, using a STA 449C Jupiter thermoanalyzer equipped with a QMC 230 mass spectrometer. The thermoanalyzer determines small changes in mass and thermal effects with high accuracy (weighing accuracy 10{sup -8} g; error in measuring thermal effects 1 mV). This permits experiments with single layers of coal particles, eliminating secondary reactions of its thermal-destruction products.

Investigation of Effects of Coal and Biomass Contaminants on the Performance of Water-Gas-Shift and Fischer-Tropsch Catalysts  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Effects of Coal Effects of Coal and Biomass Contaminants on the Performance of Water-Gas-Shift and Fischer-Tropsch Catalysts Background Coal-Biomass-to-Liquids (CBTL) processes gasify coal, biomass, and mixtures of coal/ biomass to produce synthesis gas (syngas) that can be converted to liquid hydrocarbon fuels. Positive benefits of these processes include the use of feedstocks from domestic sources and lower greenhouse gas production than can be achieved from using conventional petroleum-based fuels. However, syngas generated by coal and biomass co-gasification contains a myriad of trace contaminants that may poison the water- gas-shift (WGS) and Fischer-Tropsch (FT) catalysts used in the gas-to-liquid processes. While the effect of coal contaminants on FT processes is well studied, more research

Characterization of fly ashes from circulating fluidized bed combustion (CFBC) boilers cofiring coal and petroleum coke  

SciTech Connect (OSTI)

The chemistry, mineralogy, morphology, and particle size distribution were investigated in fly ashes from the burning of Datong (ShanXi, China) bituminous coal and the cofiring of Mideast high-sulfur petroleum coke (PC) with 30:70 (cal %) and 50:50 (cal %) blends of Datong bituminous coal in two commercial CFBC boilers. With the exception of CaO, the amounts of major oxides in the fly ashes from cofiring PC and coal were close to those of the common coal fly ashes. The PC-coal fly ashes were enriched in Ni, V, and Mo, implying these trace elements were mainly derived from PC. Ni and V, along with several other elements, such as Cr, Cu, Se, Pb, U, Th, and possibly As and Cd, increased in content with a decrease in temperature of the electrostatic precipitator (ESP). The results of chemistry, mineralogy, and morphology studies suggested that the desulfurization rate of the CFBC boilers at current conditions was low, and the PC tends to coarsen the fly ash particles and increase the loss on ignition (LOI) values, making these fly ashes unsuitable for use as a cement additive or a mineral admixture in concrete. Further studies on the combustion status of the CFBC boilers are needed if we want to be able to increase the desulfurization rate and produce high-quality fly ashes for broader and full utilization. 22 refs., 4 figs., 4 tabs.

Coal occurrence, quality and resource assessment, National Petroleum Reserve in Alaska  

SciTech Connect (OSTI)

Field studies of the Cretaceous Torok, Kukpowruk, and Corwin Formations in the western portion of the NPRA (National Petroleum Reserve in Alaska) and Cretaceos Torok, Tuktu, Grandstand, and Chandler Formations in the eastern portion of NPRA indicate that two major delta systems are responsible for most of the coal accumulation in this area. The Corwin delta in the western portion was an early Albian to Cenomanian, north and east prograding system, whereas the slightly younger mid-Albian to Cenomanian Umiat delta system prograded north and northeast in the eastern portion. Investigations of the lightologies, fossils, and primary depositional structures of these formations indicate that the Corwin system was deposited as a large, high-constructional, shaped delta on which thick and numerous coals developed on splay and interdistributary bay platforms away from the influence of the Cretaceous epicontinental sea. The Umiat delta started out as a high-constructional system but in time became wave dominated, and its shape changed to lobate.

Enhanced Prognosis for Abiotic Natural Gas and Petroleum Resources  

E-Print Network [OSTI]

The prognosis for potential resources of abiotic natural gas and petroleum depends critically upon the nature and circumstances of Earth formation. Until recently, that prognosis has been considered solely within the framework of the so-called "standard model of solar system formation", which is incorrect and leads to the contradiction of terrestrial planets having insufficiently massive cores. By contrast, that prognosis is considerably enhanced (i) by the new vision I have disclosed of Earth formation as a Jupiter-like gas giant; (ii) by core formation contemporaneous with raining out from within a giant gaseous protoplanet rather than through subsequent whole-Earth re-melting after loss of gases; (iii) by the consequences of whole-Earth decompression dynamics, which obviates the unfounded assumption of mantle convection, and; (iv) by the process of mantle decompression thermal-tsunami.

Impact of Recent Discoveries on Petroleum and Natural Gas Exploration: Emphasis on India  

E-Print Network [OSTI]

Two discoveries have greatly impacted understanding relevant to the origination and emplacement of petroleum and natural gas deposits. One discovery, pertaining to hydrocarbon formation from methane broadens significantly potential regions where abiotic petroleum and natural gas deposits might be found. The other, discovery of the physical impossibility of Earth-mantle convection, restricts the range and domain of geodynamic behavior, and leads to new insights on the formation of petroleum and natural gas deposits. This article highlights the impact and implications of those discoveries, especially as they relate to petroleum and natural gas exploration in India and throughout the world. From the reasoning developed here, the generality of the considerations involved, the understanding developed with respect to the East African Rift System, and the experience garnered from the larger and older Siberian Traps, the prognosis and potential for the region beneath the Deccan Traps of India to eventually become a major source of petroleum and natural gas seems quite favorable.

Relative permeabilities of gas and water for different rank coals  

Science Journals Connector (OSTI)

Characteristics of gas–water two-phase flow through coal seams play crucial roles in water depletion and gas production associated with coalbed methane (CBM) recovery. One of the most important characteristic is the relative permeability of gas and water which is largely dependent on gas/water saturations in coal, varying with coal ranks. For better understanding of the seepage mechanism of the gas–water flow in coal, the relative permeabilities of gas and water in different rank coals selected from south Qinshui Basin have been investigated under various gas/water saturations through water replacement with methane using an unsteady-state method. The results have shown that the ratio of effective methane permeability and absolute permeability is obviously increasing with rank, implying that the gas slippage of high rank coal has more significant effect than the low rank coal. A series of relative permeability curves for selected coals have been obtained. All of these curves show that the selected coals are featured by smaller methane permeabilities and narrow spans of two-phase flow regions and lower relative permeability, and have low methane permeabilities under irreducible water condition as well. The experiments also revealed that the selected coals exhibit high residual water saturation with low relative permeabilities of gas and water. With increasing of the maximal vitrinite reflectance, the irreducible water saturation exhibits a U-shaped tendency whereas the methane permeability under the irreducible water condition generally increases. The irreducible water saturation slightly increases with increasing of vitrinite and weakly decreases as inertinite increases, while the methane permeability under irreducible water condition is negatively related with vitrinite and positively related to inertinite to some extent. The experimental data were further parameterized to correlate the relative permeabilities of methane and water to gas saturation, showing that a correlation of power function can fit the experiments well. As a result, a permeability model incorporated with coal rank and maceral compositions with gas saturation was developed to predict the relative permeabilities of gas (methane) and water in coals.

Testing for market integration crude oil, coal, and natural gas  

SciTech Connect (OSTI)

Prompted by the contemporaneous spike in coal, oil, and natural gas prices, this paper evaluates the degree of market integration both within and between crude oil, coal, and natural gas markets. Our approach yields parameters that can be readily tested against a priori conjectures. Using daily price data for five very different crude oils, we conclude that the world oil market is a single, highly integrated economic market. On the other hand, coal prices at five trading locations across the United States are cointegrated, but the degree of market integration is much weaker, particularly between Western and Eastern coals. Finally, we show that crude oil, coal, and natural gas markets are only very weakly integrated. Our results indicate that there is not a primary energy market. Despite current price peaks, it is not useful to think of a primary energy market, except in a very long run context.

Fouling in a 160 MWe FBC boiler firing coal and petroleum coke  

Science Journals Connector (OSTI)

The 160 MWe fluidized bed combustor (FBC) boiler owned and operated by the Tennessee Valley Authority (TVA) has recently been co-fired with coal and petroleum coke (up to 50%). However, it has suffered some fouling problems. On examination of the deposits it became clear that, in only a few cases could the fouling be partially attributed to alkali metals, and even in those cases the primarily limestone-derived materials were almost quantitatively sulphated to a level which was sufficient to cause strength development by itself. In other cases, it appeared that the fouling mechanism was carbonation of the free lime component of the deposit followed by sulphation. Finally, in a few deposits which were less sulphated than bed materials and fly ash, strength development appeared to have occurred by conversion of the free lime in the deposits to Ca(OH)2, followed by carbonation. This type of agglomeration has not been reported previously in a FBC.

By contrast, that prognosis is considerably enhanced (i) by the new vision I have disclosed of Earth formation as a Jupiter-like gas giant; (ii) by core formation contemporaneous with raining out from within a giant gaseous protoplanet rather than through subsequent whole-Earth re-melting after loss of gases; (iii) by the consequences of whole-Earth decompression dynamics, which obviates the unfounded assumption of mantle convection, and; (iv) by the process of mantle decompression thermal-tsunami. The latter, in addition to accounting for much of the heat leaving the Earth's surface, for the geothermal gradient observed in the crust, for substantial volcanism, and possibly for earthquake generation as well, also might enhance the prognosis for future abiotic energy supplies by pressurizing and heating the base of the crust, a potential collection point for abiotic mantle methane or other mantle-derived carbon-containing matter.

Evaluation of fly ash from co-combustion of coal and petroleum coke for use in concrete  

SciTech Connect (OSTI)

An investigation of fly ash (FA) produced from various blends of coal and petroleum coke (pet coke) fired at Belledune Generating Station, New Brunswick, Canada, was conducted to establish its performance relative to FA derived from coal-only combustion and its compliance with CSA A3000. The FA samples were beneficiated by an electrostatic separation process to produce samples for testing with a range of loss-on-ignition (LOI) values. The results of these studies indicate that the combustion of pet coke results in very little inorganic residue (for example, typically less than 0.5% ash) and the main impact on FA resulting from the co-combustion of coal and up to 25% pet coke is an increase in the unburned carbon content and LOI values. The testing of FA after beneficiation indicates that FA produced from fuels with up to 25% pet coke performs as good as FA produced from the same coal without pet coke.

Impact of Recent Discoveries on Petroleum and Natural Gas Exploration: Emphasis on India  

E-Print Network [OSTI]

Two discoveries have greatly impacted understanding relevant to the origination and emplacement of petroleum and natural gas deposits. One discovery, pertaining to hydrocarbon formation from methane broadens significantly potential regions where abiotic petroleum and natural gas deposits might be found. The other, discovery of the physical impossibility of Earth-mantle convection, restricts the range and domain of geodynamic behavior, and leads to new insights on the formation of petroleum and natural gas deposits. This article highlights the impact and implications of those discoveries, especially as they relate to petroleum and natural gas exploration in India and throughout the world. From the reasoning developed here, the generality of the considerations involved, the understanding developed with respect to the East African Rift System, and the experience garnered from the larger and older Siberian Traps, the prognosis and potential for the region beneath the Deccan Traps of India to eventually become a m...

Hard truths: facing the hard truths about energy. Topic Paper No. 18: Coal to liquids and gas  

SciTech Connect (OSTI)

The report presents the issues associated with and the potential of coal to liquids (CTL) and coal to gas (CTG) technologies. The other important outcome from this report is to view and understand the inputs and assumptions from various publications and the range of production estimates from CTG and CTL technology. The examination of the publications demonstrates a large uncertainty for CTL, due to various assumptions from petroleum price to technological abilities. Key assumptions are left unexamined, such as product transportation, labor, equipment availability, and environmental risk. Overall, the published CTL production estimates are small in the total global petroleum market perspective; even in the most optimistic scenario the volume from CTL amounts to only 20% of the U.S. petroleum market in the Southern States Energy Board (SSEB) report. The National Coal Council (NCC) saw a 10% market share, whereas the various Energy Information Administration (EIA) scenarios saw 0% to 6% of the U.S market share. The NCC and SSEB both mentioned the added benefit of using the CO{sub 2} for enhanced oil recovery (EOR). It begins by introducing the process, giving a detailed technological understanding, and then outlining each issue with each report from coal availability to oil price assumptions. The incremental gains from CTL and other technology areas, such as oil shale, could have a significant impact on U.S. energy cost and foreign dependency. The use of coal allows the added benefit of relying on a resource that is domestically more plentiful than petroleum, but this reliance must be carefully balanced with the economics of developing the resource, since CTL facilities can cost more than $1 billion per 10,000 days of production, which implicates the competitiveness of the U.S. economy within the global economy. 33 refs.

High temperature alkali corrosion of ceramics in coal gas  

SciTech Connect (OSTI)

High temperature alkali corrosion has been known to cause premature failure of ceramic components used in advanced high temperature coal combustion systems such as coal gasification and clean-up, coal fired gas turbines, and high efficiency heat engines. The objective of this research is to systematically evaluate the alkali corrosion resistance of the most commonly used structural ceramics including silicon carbide, silicon nitride, cordierite, mullite, alumina, aluminum titanate, zirconia, and fireclay glass. The study consists of identification of the alkali reaction products (phase equilibria) and the kinetics of the alkali reactions as a function of temperature and time.

Economical production of transportation fuels from coal, natural gas, and other carbonaceous feedstocks  

SciTech Connect (OSTI)

The Nation`s economy and security will continue to be vitally linked to an efficient transportation system of air, rail, and highway vehicles that depend on a continuous supply of liquid fuels at a reasonable price and with characteristics that can help the vehicle manufacturers meet increasingly strict environmental regulations. However, an analysis of US oil production and demand shows that, between now and 2015, a significant increase in imported oil will be needed to meet transportation fuel requirements. One element of an overall Department of Energy`s (DOE) strategy to address this energy security issue while helping meet emissions requirements is to produce premium transportation fuels from non-petroleum feedstocks, such as coal, natural gas, and biomass, via Fischer-Tropsch (F-T) and other synthesis gas conversion technologies.

Production of coal-based fuels and value-added products: coal to liquids using petroleum refinery streams  

SciTech Connect (OSTI)

We are studying several processes that utilize coal, coal-derived materials, or biomass in existing refining facilities. A major emphasis is the production of a coal-based replacement for JP-8 jet fuel. This fuel is very similar to Jet A and jet A-1 in commercial variation, so this work has significant carry-over into the private sector. We have been focusing on three processes that would be retrofitted into a refinery: (1) coal tar/refinery stream blending and hydro-treatment; (2) coal extraction using refinery streams followed by hydro-treatment; and (3) co-coking of coal blended with refinery streams. 4 figs., 5 tabs.

Solar coal gasification reactor with pyrolysis gas recycle  

DOE Patents [OSTI]

Coal (or other carbonaceous matter, such as biomass) is converted into a duct gas that is substantially free from hydrocarbons. The coal is fed into a solar reactor (10), and solar energy (20) is directed into the reactor onto coal char, creating a gasification front (16) and a pyrolysis front (12). A gasification zone (32) is produced well above the coal level within the reactor. A pyrolysis zone (34) is produced immediately above the coal level. Steam (18), injected into the reactor adjacent to the gasification zone (32), reacts with char to generate product gases. Solar energy supplies the energy for the endothermic steam-char reaction. The hot product gases (38) flow from the gasification zone (32) to the pyrolysis zone (34) to generate hot char. Gases (38) are withdrawn from the pyrolysis zone (34) and reinjected into the region of the reactor adjacent the gasification zone (32). This eliminates hydrocarbons in the gas by steam reformation on the hot char. The product gas (14) is withdrawn from a region of the reactor between the gasification zone (32) and the pyrolysis zone (34). The product gas will be free of tar and other hydrocarbons, and thus be suitable for use in many processes.

Far- and mid-infrared spectroscopy of complex organic matter of astrochemical interest: coal, heavy petroleum fractions, and asphaltenes  

E-Print Network [OSTI]

The coexistence of a large variety of molecular species (i.e., aromatic, cycloaliphatic and aliphatic) in several astrophysical environments suggests that unidentified IR emission (UIE) occurs from small solid particles containing a mix of aromatic and aliphatic structures (e.g., coal, petroleum, etc.), renewing the astronomical interest on this type of materials. A series of heavy petroleum fractions namely DAE, RAE, BQ-1, and asphaltenes derived from BQ-1 were used together with anthracite coal and bitumen as model compounds in matching the band pattern of the emission features of proto-planetary nebulae (PPNe). All the model materials were examined in the mid-infrared (2.5-16.7 um) and for the first time in the far-infrared (16.7-200 um), and the IR bands were compared with the UIE from PPNe. The best match of the PPNe band pattern is offered by the BQ-1 heavy aromatic oil fraction and by its asphaltenes fraction. Particularly interesting is the ability of BQ-1 to match the band pattern of the aromatic-ali...

Coal in National Petroleum Reserve in Alaska (NPRA): framework geology and resources  

SciTech Connect (OSTI)

The North Slope of Alaska contains huge resources of coal, much of which lies within NPRA. The main coal-bearing units, the Corwin and Chandler Formations of the Nanushuk Group (Lower and Upper Cretaceous), underlie about 20,000 mi/sup 2/ (51,800 km/sup 2/) of NPRA. They contain low-sulfur, low-ash, and probable coking-quality coal in gently dipping beds as thick as 20 ft (6.1 m) within stratigraphic intervals as thick as 4500 ft (1370 m). Lesser coal potential occurs in other Upper Cretaceous units and in Lower Mississippian and Tertiary strata. The river-dominated Corwin and Umiat deltas controlled the distribution of Nanushuk Group coal-forming environments. Most organic deposits formed on delta plains; fewer formed in alluvial plain or delta-front environments. Most NPRA coal beds are expected to be lenticular and irregular, as they probably accumulated in interdistributary basins, infilled bays, or inland flood basins, whereas some blanket beds may have formed on broad, slowly sinking, delta lobes. The major controls of coal rank and degree of deformation were depth of burial and subsequent tectonism. Nanushuk Group coal resources in NPRA are estimated to be as much as 2.75 trillion short tons. This value is the sum of 1.42 trillion short tons of near-surface (< 500 ft or 150 m of overburden) bituminous coal, 1.25 trillion short tons of near-surface subbituminous coal, and 0.08 trillion shorts tons of more deeply buried subbituminous coal. These estimates indicate that the North Slope may contain as much as one-third of the United States coal potential.

Geochemistry of coal from Cretaceous Corwin and Chandler formations, National Petroleum Reserve in Alaska (NPRA)  

SciTech Connect (OSTI)

Ninety coal samples from these formations within NPRA were collected and analyzed in order to evaluate coal quality and elemental distribution. Their apparent rank ranges from lignite A in the northern part of NPRA to high-volatile AS bituminous coal in the southern part. Mean vitrinite reflectance values range from 0.65 to 0.74%. Some Corwin Formation coal samples west of NPRA have coking potential with free-swelling indexes between 3.0 and 5.0. Compared to other western United States Cretaceous coal, NPRA coal is significantly lower in ash, volatile matter, O, Si, Al, Ca, Fe, Ti, Cu, F, Li, Mn, Mo, Pb, Sb, Se, Th, and Zn. Statistical comparisons of element concentrations indicate that the mean content of Si, Al, K, Li, Sc, Y, and Yb increases as the mean ash content increases (correlation coefficient at least 0.7). Sulfur values are extremely low (0.1%), and elements that normally show positive correlation with sulfur, such as Fe, As, Cd, Co, Cu, Mo, Pb, and Zn, are also low. Therefore, coal from NPRA can be characterized by low ash and sulfur contents and low contents of elements of environmental concern, such as As, Be, Hg, Mo, Sb, and Se. The elements found to have positive correlations with ash content are probably present as aluminosilicate or stable oxide minerals. Variations in element content and quality of NPRA coal were probably influenced by the geochemical conditions that existed in the Corwin and Umiat delta systems.

Further investigation of the impact of the co-combustion of tire-derived fuel and petroleum coke on the petrology and chemistry of coal combustion products  

SciTech Connect (OSTI)

A Kentucky cyclone-fired unit burns coal and tire-derived fuel, sometimes in combination with petroleum coke. A parallel pulverized combustion (pc) unit at the same plant burns the same coal, without the added fuels. The petrology, chemistry, and sulfur isotope distribution in the fuel and resulting combustion products was investigated for several configurations of the fuel blend. Zinc and Cd in the combustion products are primarily contributed from the tire-derived fuel, the V and Ni are primarily from the petroleum coke, and the As and Hg are probably largely from the coal. The sulfur isotope distribution in the cyclone unit is complicated due to the varying fuel sources. The electrostatic precipitator (ESP) array in the pc unit shows a subtle trend towards heavier S isotopic ratios in the cooler end of the ESP.

Wetland regulations affecting coal mining and oil and gas operations  

SciTech Connect (OSTI)

Although the total acreage of wetlands in Appalachia is relatively small, the impact of wetlands on coal mining and the oil and gas industry can be significant. Wetlands are strongly protected from degradation and diminution under both federal and state regulatory programs, and both environmental protection groups and the public are concerned about the disturbance of natural wetlands. If an owner or operator of site is unable to obtain an appropriate permit, the presence of wetlands may completely preclude energy development. This article strives to provide an insight into the regulatory scheme surrounding wetlands and the risks of wetlands development.

Size exclusion chromatography for the unambiguous detection of aliphatics in fractions from petroleum vacuum residues, coal liquids, and standard materials, in the presence of aromatics  

SciTech Connect (OSTI)

A method has been developed using size exclusion chromatography (SEC) in heptane eluent that can detect aliphatics unambiguously without fractionation to remove aromatics. Spherical molecules such as colloidal silicas elute at the exclusion limit, while alkanes up to C{sub 50} elute through the porosity of the column. Detection of aliphatics was defined by use of an evaporative light scattering (ELS) detector with the simultaneous absence of UV absorbance at 300 nm. Alkanes smaller than C{sub 12} were not detected because the conditions of operation of the ELS caused their evaporation. All aromatics eluted after the permeation limit of about 25 min and were not detected until well after 45 min by their UV absorbance. The SEC method was applied to petroleum vacuum residues and coal liquids, and their fractions were soluble in pentane or heptane. High-temperature (HT) GC-MS confirmed the presence of alkanes in the pentane- and heptane-soluble fractions of petroleum vacuum residues, but did not elute any of the aromatics known to be present from SEC. Alkanes were examined in pentane-soluble fractions of a coal digest and a low-temperature coal tar; alkanes up to C{sub 40} were detected in the low-temperature tar and, although present in the digest, were masked by aromatics. No alkanes were detected by either SEC or HT GC-MS in fractions from a coal tar pitch. Aromatics in coal liquids and one petroleum residue were also examined by SEC using NMP as eluent and by UV fluorescence spectroscopy. The SEC method will find application to pentane- and heptane-soluble fractions of petroleum liquids and coal liquids where the alkanes are concentrated relative to the more abundant aromatics. 43 refs., 10 figs., 2 tabs.

Manganese-based sorbents for coal gas desulfurization  

SciTech Connect (OSTI)

The intent of this study is to perform a preliminary screening on a particular Mn-based sorbent, CST-939 (from Chemetals), for hot gas desulfurization. The purpose of the preliminary screening is to determine which temperature and type of coal gas this sorbent demonstrates the greatest capacity and efficiency for sulfur removal. The following conclusions were made from the data collected on the CST-939 sorbent: The sorbent efficiency and capacity are much greater at 343{degrees}C (650{degrees}F) than at 871{degrees}C (1,600{degrees}F). The sorbent efficiency and capacity are much greater in the presence of the more highly-reducing Shell gas than with the less-reducing KRW gas. The sorbent showed tremendous capacity for sulfur pickup, with actual loadings as high as 21 weight percent. Oxidative regeneration at 871{degrees}C (1,600{degrees}F) appeared to decompose sulfate; however, unusually high SO{sub 2} release during the second sulfidations and/or reductive regenerations indicated incomplete regeneration. The average crush strength of the reacted sorbent did not indicate any loss of strength as compared to the fresh sorbent. Superior sorbent performance was obtained in the presence of simulated Shell gas at 538{degrees}C (1,000{degrees}F).

Development of biological coal gasification (MicGAS Process)  

SciTech Connect (OSTI)

The overall goal of the project is to develop an advanced, clean coal biogasification (MicGAS) Process. The objectives of the research during FY 1993--94 were to: (1) enhance kinetics of methane production (biogasification, biomethanation) from Texas lignite (TxL) by the Mic-1 consortium isolated and developed at ARCTECH, (2) increase coal solids loading, (3) optimize medium composition, and (4) reduce retention time. A closer analysis of the results described here indicate that biomethanation of TxL at >5% solids loading is feasible through appropriate development of nutrient medium and further adaptation of the microorganisms involved in this process. Further understanding of the inhibitory factors and some biochemical manipulations to overcome those inhibitions will hasten the process considerably. Results are discussed on the following: products of biomethanation and enhance of methane production including: bacterial adaptation; effect of nutrient amendment substitutes; effects of solids loading; effect of initial pH of the culture medium; effect of hydrogen donors and carbon balance.

Silica membranes for hydrogen separation from coal gas. Final report  

SciTech Connect (OSTI)

This project is a continuation of a previous DOE-UCR project (DE-FG22- 89PC89765) dealing with the preparation of silica membranes highly permselective to hydrogen at elevated temperatures, suitable for hydrogen separation from coal gas. The membranes prepared in the previous project had very high selectivity but relatively low permeance. Therefore, the general objectives of this project were to improve the permeance of these membranes and to obtain fundamental information about membrane structure and properties. The specific objectives were: (1) to explore new silylation reagents and reaction conditions with the purpose of reducing the thickness and increasing the permeance of silica membranes prepared by chemical vapor deposition (CVD), (2) to characterize the membrane structure, (3) to delineate mechanism and kinetics of deposition, (4) to measure the permeability of silica layers at different extents of deposition, and (5) to mathematically model the relationship between structure and deposition kinetics.

Process for the production of fuel gas from coal  

DOE Patents [OSTI]

An improved apparatus and process for the conversion of hydrocarbonaceous materials, such as coal, to more valuable gaseous products in a fluidized bed gasification reaction and efficient withdrawal of agglomerated ash from the fluidized bed is disclosed. The improvements are obtained by introducing an oxygen containing gas into the bottom of the fluidized bed through a separate conduit positioned within the center of a nozzle adapted to agglomerate and withdraw the ash from the bottom of the fluidized bed. The conduit extends above the constricted center portion of the nozzle and preferably terminates within and does not extend from the nozzle. In addition to improving ash agglomeration and withdrawal, the present invention prevents sintering and clinkering of the ash in the fluidized bed and permits the efficient recycle of fine material recovered from the product gases by contacting the fines in the fluidized bed with the oxygen as it emanates from the conduit positioned within the withdrawal nozzle. Finally, the present method of oxygen introduction permits the efficient recycle of a portion of the product gases to the reaction zone to increase the reducing properties of the hot product gas.

Biological upgrading of coal-derived synthesis gas: Final report  

SciTech Connect (OSTI)

The technical feasibility of the biological conversion of coal synthesis gas to methane has been demonstrated in the University of Arkansas laboratories. Cultures of microorganisms have been developed which achieve total conversion in the water gas shift and methanation reactions in either mixed or pure cultures. These cultures carry out these conversions at ordinary temperatures and pressures, without sulfur toxicity. Several microorganisms have been identified as having commercial potential for producing methane. These include a mixed culture of unidentified bacteria; P. productus which produces acetate, a methane precursor; and Methanothrix sp., which produces methane from acetate. These cultures have been used in mixed reactors and immobilized cell reactors to achieve total CO and H/sub 2/ conversion in a retention time of less than two hours, quite good for a biological reactor. Preliminary economic projections indicate that a biological methanation plant with a size of 5 x 10/sup 10/ Btu/day can be economically attractive. 42 refs., 26 figs., 86 tabs.

Ford Liquefied Petroleum Gas-Powered F-700 May Set Sales Records  

Alternative Fuels and Advanced Vehicles Data Center [Office of Energy Efficiency and Renewable Energy (EERE)]

he introduction in 1992 of an he introduction in 1992 of an American-made truck with a fully factory-installed/war- ranted liquefied petroleum gas (LPG) engine represents another "Ford first" in the alternative fuel arena. Now the company has introduced an LPG- powered F-700, a medium/heavy- duty truck. According to Tom Steckel, Ford's medium-duty marketing man- ager, Ford's latest sales figures already prove the alternative fuel F-700's popularity. With a little more than 10 months of the model year finished, Ford has produced 1600 units and ordered 600 more, for a total of 2200 units. That's triple the number of LPG units produced and ordered at the same time last year. In addition, the possibility of applying federal and state tax credits is being investigated.

Forecast of Geological Gas Hazards for “Three-Soft” Coal Seams in Gliding Structural Areas  

Science Journals Connector (OSTI)

Gas outbursts from “three-soft” coal seams (soft roof, soft floor and soft coal) constitute a very serious problem in the Ludian gliding structure area in western Henan. By means of theories and methods of gas geology, structural geology, coal petrology and rock tests, we have discussed the effect of control of several physical properties of soft roof on gas preservation and proposed a new method of forecasting gas geological hazards under open structural conditions. The result shows that the areas with type III or IV soft roofs are the most dangerous areas where gas outburst most likely can take place. Therefore, countermeasures should be taken in these areas to prevent gas outbursts.

Modeling of gas generation from the Cameo coal zone in the Piceance Basin Colorado  

SciTech Connect (OSTI)

The gas generative potential of the Cretaceous Cameo coal in the Piceance Basin, northwestern Colorado, was evaluated quantitatively by sealed gold tube pyrolysis. The H/C and O/C elemental ratios show that pyrolyzed Cameo coal samples follow the Van Krevelen humic coal evolution pathway, reasonably simulating natural coal maturation. Kinetic parameters (activation energy and frequency factor) for gas generation and vitrinite reflectance (R{sub o}) changes were calculated from pyrolysis data. Experimental R{sub o} results from this study are not adequately predicted by published R{sub o} kinetics and indicate the necessity of deriving basin-specific kinetic parameters when building predictive basin models. Using derived kinetics for R{sub o}, evolution and gas generation, basin modeling was completed for 57 wells across the Piceance Basin, which enabled the mapping of coal-rank and coalbed gas potential. Quantities of methane generated at approximately 1.2% R{sub o} are about 300 standard cubic feet per ton (scf/ton) and more than 2500 scf/ton (in-situ dry-ash-free coal) at R{sub o}, values reaching 1.9%. Gases generated in both low- and high-maturity coals are less wet, whereas the wetter gas is expected where R{sub o} is approximately 1.4-1.5%. As controlled by regional coal rank and net coal thickness, the largest in-place coalbed gas resources are located in the central part of the basin, where predicted volumes exceed 150 bcf/mi, excluding gases in tight sands.

A comparative study of the adsorption of petroleum products by micro- and macroporous carbon sorbents was performed. For this purpose, four carbon sorbent samples prepared from various raw materials by various processing techniques were used. The following raw materials were used: (1) fuel mill from the Mezinoskoe deposit; (2) wood waste, shaving and sawdust in ratio (%) of 50:50; and (3) low-caking gas coal of the 2G group from the mine im.Kirova in the Kuznetsk Basin. The pore structures and adsorption capacities of these sorbents for petroleum products were studied. It was found that the adsorption of petroleum products on porous and nonporous carbon sorbents occurred in different manners. In this case, macroporous sorbents with a weakly developed structure of sorbing micro- and mesopores exhibited a maximum capacity for petroleum products.

The Research and Motor octane numbers of Liquefied Petroleum Gas (LPG)  

Science Journals Connector (OSTI)

This paper presents an experimental study of the Research (RON) and Motor (MON) octane numbers of Liquefied Petroleum Gas (LPG). A comprehensive set of RON and MON data for mixtures of propane, propylene (propene), n-butane and iso-butane are presented, using a method that is consistent with the currently active ASTM Research and Motor test methods for liquid fuels. Empirical models which relate LPG composition to its RON and MON are then developed, such that the simplest relationships between the constituent species’ mole fractions and the mixture octane rating are achieved. This is used to determine the degree of non-linearity between the composition and the RON and MON of different LPG mixtures. Finally, implications for LPG fuel quality standards are discussed briefly, as part of a suggested, more substantial undertaking by the community which also revisits the standard test procedures for measuring the RON and MON of LPG.

Advanced coal-fueled gas turbine systems. Final report  

SciTech Connect (OSTI)

The configuration of the subscale combustor has evolved during the six years of this program from a system using only an impact separator to remove particulates to a system which also included a slagging cyclone separator before the lean-quench combustor. The system also now includes active slag tapping after the impact separator rather than a bucket to collect the slag. The subscale 12 MM Btu/hr (higher heating value, HHV) slagging combustor has demonstrated excellent coal-fired operation at 6 atm. The combustor has fired both coal-water mixtures (CWM) and pulverized coal (PC). Three Wyoming subbituminous coals and two bituminous coals have been successfully fired in the TVC. As a result of this active testing, the following conclusions may be drawn: (1) it was possible to achieve the full design thermal capacity of 12 MM Btu/hr with the subscale slagging combustor, while burning 100% pulverized coal and operating at the design pressure of 6 atm; (2) because of the separate-chamber, rich-lean design of the subscale slagging combustor, NO{sub x} emissions that easily meet the New Source Performance Standards (NSPS) limits were achieved; (3) carbon burnout efficiency was in excess of 99% when 100% coal-fired; (4) ninety percent of the ash can be separated as slag in the impact separator, and a total 98 to 99% removed with the addition of the slagging cyclone separator; (5) Objectives for third-stage exit temperature (1850{degrees}F), and exit temperature pattern factor (14%) were readily achieved; (6) overall pressure loss is currently an acceptable 5 to 6% without cyclone separator and 7 to 9% with the cyclone; and (7) feeding pulverized coal or sorbent into the combustor against 6 atm pressure is achievable.

Environmental trends in Asia are accelerating the introduction of clean coal technologies and natural gas  

SciTech Connect (OSTI)

This paper examines the changing energy mix for Asia to 2020, and impacts of increased coal consumption on Asia`s share of world SO{sub 2} and CO{sub 2} emissions. Stricter SO{sub 2} emissions laws are summarized for eight Asian economies along with implications for fuel and technology choices. The paper compares the economics of different technologies for coal and natural gas in 1997 and in 2007. Trends toward introducing clean coal technologies and the use of natural gas will accelerate in response to tighter environmental standards by 2000. The most important coal conversion technology for Asia, particularly China, in the long term is likely to be integrated gasification combined-cycle (IGCC), but only under the assumption of multiple products.

Combustion of Illinois coals and chars with natural gas. Final technical report, September 1, 1991--August 31, 1992  

SciTech Connect (OSTI)

Combined combustion of coal and natural gas offers advantages compared to burning coal or natural gas alone. For example, low volatile coals (or chars) derived from treatment or gasification processes can be of limited use due to their poor flammability characteristics. However, the use of natural gas in conjunction with the solid fuel can provide the necessary ``volatiles`` to enhance the combustion. Also, natural gas provides a clean cofiring fuel source which can enhance the usefulness of coals with high sulfur content. Addition of natural gas may reduce SO{sub x} emissions through increased sulfur retention in the ash and reduce NO{sub x} emissions by varying local stoichiometry and temperature levels. This research program addresses the contributions and the mechanisms of cofiring natural gas with Illinois coal through studies of particle ignition, burning rates and ash characterization.

Modeling gas displacement kinetics in coal with Maxwell-Stefan diffusion theory  

SciTech Connect (OSTI)

The kinetics of binary gas counter-diffusion and Darcy flow in a large coal sample were modeled, and the results compared with data from experimental laboratory investigations. The study aimed for a better understanding of the CO{sub 2}-sequestration enhanced coalbed methane (ECBM) recovery process. The transport model used was based on the bidisperse diffusion mechanism and Maxwell-Stefan (MS) diffusion theory. This provides an alternative approach to simulate multicomponent gas diffusion and flow in bulk coals. A series of high-stress core flush tests were performed on a large coal sample sourced from a Bowen Basin coal mine in Queensland, Australia to investigate the kinetics of one gas displacing another. These experimental results were used to derive gas diffusivities, and to examine the predictive capability of the diffusion model. The simulations show good agreements with the displacement experiments revealing that MS diffusion theory is superior for describing diffusion of mixed gases in coals compared with the constant Fick diffusivity model. The optimized effective micropore and macropore diffusivities are comparable with experimental measurements achieved by other researchers.

New developments in coal briquetting technology  

SciTech Connect (OSTI)

Briquetting of coal has been with us for well over a century. In the earliest applications of coal briquetting, less valuable fine coal was agglomerated into briquettes using a wide variety of binders, including coal tar, pitch and asphalt. Eventually, roll briquetters came into more widespread use, permitting the process to become a continuous one. Coal briquetting went out of favor during the 1950s in most of the industrialized world. The major reason for this decline in use was the discovery that the coal gas distillates used for binders were harmful to human health. Also, the abundance of cheap petroleum made coal briquettes a less attractive alternative as an industrial or domestic fuel. The re-emergence of coal as a primary industrial fuel and also its increased prominence as a fuel for thermal electric power stations led to a large increase in the annual volume of coal being mined worldwide. Coal preparation technology steadily improved over the years with the general exception of fine coal preparation. The processes available for treating this size range were considerably more expensive per unit mass of coal treated than coarse coal processes. Also, costly dewatering equipment was required after cleaning to remove surface moisture. Even with dewatering, the high surface area per unit mass of fine coal versus coarse coal resulted in high moisture contents. Therefore, little incentive existed to improve the performance of fine coal processes since this would only increase the amount of wet coal fines which would have to be dealt with. With such an ever-increasing volume of coal fines being created each year, there emerged an interest in recovering this valuable product. Several schemes were developed to recover coal fines discarded in abandoned tailings impoundments by previous operations.

Secondary porosity and permeability of coal vs. gas composition and pressure  

SciTech Connect (OSTI)

We have been investigating the sequestration of atmospheric pollutants by injection into coal seams while at the same time enhancing hydrocarbon productivity by displacement of methane with pollutants. We found that changing the composition of the gas sorbed into the coal changes the porosity and permeability of the coal natural-fracture system owing to gas-content changes, which cause matrix swelling or shrinkage due to relative adsorption of different gases. We collected sufficient information to develop a method for predicting the permeability and porosity of a coalbed as a function of the secondary porosity system (SPS) pressure and the gas content and composition of the primary porosity system (PPS). The method uses data from injection/falloff tests with water and/or a weaker adsorbing gas (WAG) than CH{sub 4} and a stronger adsorbing gas (SAG) than CH{sub 4}. Estimates of effective permeability to gas and water obtained from these tests are used with an iterative computation procedure subject to constraints to solve for equivalent SPS porosity and absolute permeability at atmospheric pressure. Once calibrated, the model can be used to predict a coalbed's permeability and porosity as a function of injection pressure and injected-fluid composition, which in turn are used to predict injection performance. The model is applicable to production forecasts to account for SPS permeability and porosity changes as reservoir pressure declines with changes in gas composition. This paper describes the new model and discusses well-test procedures to obtain the data required for model calibration. Also included are coal property estimates resulting from Alberta Medicine River (Manville) coal core and test data and an example model calibration.

Enhancing the use of coals by gas reburning-sorbent injection  

SciTech Connect (OSTI)

Clean Coal Technology implies the use of coal in an environmentally acceptable manner. Coal combustion results in the emission of two types of acid rain precursors: oxides of sulfur (SO{sub x}) and oxides of nitrogen (NO{sub x}). This Clean Coal Technology project will demonstrate a combination of two developed technologies to reduce both NO{sub x} and SO{sub x} emissions: gas reburning and calcium based dry sorbent injection. The demonstrations will be conducted on two pre-NSPS utility boilers representative of the US boilers which contribute significantly to the inventory of acid rain precursor emissions: tangentially and cyclone fired units. Because of cost growth and lack of available funding, no further work has been done after Phase 1 at site B; the wall fired unit.

An evaluation of Substitute natural gas production from different coal gasification processes based on modeling  

Science Journals Connector (OSTI)

Coal and lignite will play a significant role in the future energy production. However, the technical options for the reduction of CO2 emissions will define the extent of their share in the future energy mix. The production of synthetic or substitute natural gas (SNG) from solid fossil fuels seems to be a very attractive process: coal and lignite can be upgraded into a methane rich gas which can be transported and further used in high efficient power systems coupled with CO2 sequestration technologies. The aim of this paper is to present a modeling analysis comparison between substitute natural gas production from coal by means of allothermal steam gasification and autothermal oxygen gasification. In order to produce SNG from syngas several unit operations are required such as syngas cooling, cleaning, potential compression and, of course, methanation reactors. Finally the gas which is produced has to be conditioned i.e. removal of unwanted species, such as CO2 etc. The heat recovered from the overall process is utilized by a steam cycle, producing power. These processes were modeled with the computer software IPSEpro™. An energetic and exergetic analysis of the coal to SNG processes have been realized and compared.

Advanced coal-fueled gas turbine systems: Subscale combustion testing. Topical report, Task 3.1  

SciTech Connect (OSTI)

This is the final report on the Subscale Combustor Testing performed at Textron Defense Systems` (TDS) Haverhill Combustion Laboratories for the Advanced Coal-Fueled Gas Turbine System Program of the Westinghouse Electric Corp. This program was initiated by the Department of Energy in 1986 as an R&D effort to establish the technology base for the commercial application of direct coal-fired gas turbines. The combustion system under consideration incorporates a modular staged, rich-lean-quench, Toroidal Vortex Slogging Combustor (TVC) concept. Fuel-rich conditions in the first stage inhibit NO{sub x} formation from fuel-bound nitrogen; molten coal ash and sulfated sorbent are removed, tapped and quenched from the combustion gases by inertial separation in the second stage. Final oxidation of the fuel-rich gases, and dilution to achieve the desired turbine inlet conditions are accomplished in the third stage, which is maintained sufficiently lean so that here, too, NO{sub x} formation is inhibited. The primary objective of this work was to verify the feasibility of a direct coal-fueled combustion system for combustion turbine applications. This has been accomplished by the design, fabrication, testing and operation of a subscale development-type coal-fired combustor. Because this was a complete departure from present-day turbine combustors and fuels, it was considered necessary to make a thorough evaluation of this design, and its operation in subscale, before applying it in commercial combustion turbine power systems.

Kinetics of Direct Oxidation of H2S in Coal Gas to Elemental Sulfur  

SciTech Connect (OSTI)

Removal of hydrogen sulfide (H{sub 2}S) from coal gasifier gas and sulfur recovery are key steps in the development of Department of Energy's (DOE's) advanced Vision 21 plants that produce electric power and clean transportation fuels with coal and natural gas. These Vision 21 plants will require highly clean coal gas with H{sub 2}S below 1 ppm and negligible amounts of trace contaminants such as hydrogen chloride, ammonia, alkali, heavy metals, and particulate. The conventional method of sulfur removal and recovery employing amine, Claus, and tail-gas treatment is very expensive. A second generation approach developed under DOE's sponsorship employs hot-gas desulfurization (HGD) using regenerable metal oxide sorbents followed by Direct Sulfur Recovery Process (DSRP). However, this process sequence does not remove trace contaminants and is targeted primarily towards the development of advanced integrated gasification combined cycle (IGCC) plants that produce electricity (not both electricity and transportation fuels). There is an immediate as well as long-term need for the development of cleanup processes that produce highly clean coal gas for next generation Vision 21 plants. To this end, a novel process is now under development at several research organizations in which the H{sub 2}S in coal gas is directly oxidized to elemental sulfur over a selective catalyst. Such a process is ideally suited for coal gas from commercial gasifiers with a quench system to remove essentially all the trace contaminants except H{sub 2}S. The direct oxidation of H{sub 2}S to elemental sulfur in the presence of SO{sub 2} is ideally suited for coal gas from commercial gasifiers with a quench system to remove essentially all the trace contaminants except H{sub 2}S. This direct oxidation process has the potential to produce a super clean coal gas more economically than both conventional amine-based processes and HGD/DSRP. The objectives of this research are to measure kinetics of direct oxidation of H{sub 2}S to elemental sulfur in the presence of a simulated coal gas mixture containing SO{sub 2}, H{sub 2}, and moisture, using 160-{micro}m C-500-04 alumina catalyst particles and 400 square cells/inch{sup 2}, {gamma}-Al{sub 2}O{sub 3}-wash-coated monolithic catalyst, and various reactors such as a micro packed-bed reactor, a micro bubble reactor, and a monolithic catalyst reactor, and to develop kinetic rate equations and model the direct oxidation process to assist in the design of large-scale plants. This heterogeneous catalytic reaction has gaseous reactants such as H{sub 2}S and SO{sub 2}. However, this heterogeneous catalytic reaction has heterogeneous products such as liquid elemental sulfur and steam.

Analysis of CO2 Separation from Flue Gas, Pipeline Transportation, and Sequestration in Coal  

SciTech Connect (OSTI)

This report was written to satisfy a milestone of the Enhanced Coal Bed Methane Recovery and CO2 Sequestration task of the Big Sky Carbon Sequestration project. The report begins to assess the costs associated with separating the CO2 from flue gas and then injecting it into an unminable coal seam. The technical challenges and costs associated with CO2 separation from flue gas and transportation of the separated CO2 from the point source to an appropriate sequestration target was analyzed. The report includes the selection of a specific coal-fired power plant for the application of CO2 separation technology. An appropriate CO2 separation technology was identified from existing commercial technologies. The report also includes a process design for the chosen technology tailored to the selected power plant that used to obtain accurate costs of separating the CO2 from the flue gas. In addition, an analysis of the costs for compression and transportation of the CO2 from the point-source to an appropriate coal bed sequestration site was included in the report.

Stable isotope geochemistry of coal bed and shale gas and related production waters: A review  

Science Journals Connector (OSTI)

Abstract Coal bed and shale gas can be of thermogenic, microbial or of mixed origin with the distinction made primarily on the basis of the molecular and stable isotope compositions of the gases and production waters. Methane, ethane, carbon dioxide and nitrogen are the main constituents of coal bed and shale gases, with a general lack of C2+ hydrocarbon species in gases produced from shallow levels and more mature coals and shales. Evidence for the presence of microbial gas include ?13C–CH4 values less than ? 50‰, covariation of the isotope compositions of gases and production water, carbon and hydrogen isotope fractionations consistent with microbial processes, and positive ?13C values of dissolved inorganic carbon in production waters. The CO2-reduction pathway is distinguished from acetate/methyl-type fermentation by somewhat lower ?13C–CH4 and higher ?D–CH4, but can also have overlapping values depending on the openness of the microbial system and the extent of substrate depletion. Crossplots of ?13C–CH4 versus ?13C–CO2 and ?D–CH4 versus ?13C–H2O may provide a better indication of the origin of the gases and the dominant metabolic pathway than the absolute carbon and hydrogen isotope compositions of methane. In the majority of cases, microbial coal bed and shale gases have carbon and hydrogen isotope fractionations close to those expected for CO2 reduction. Primary thermogenic gases have ?13C–CH4 values greater than ? 50‰, and ?13C values that systematically increase from C1 to C4 and define a relatively straight line when plotted against reciprocal carbon number. Although coals and disseminated organic matter in shales represent a continuum as hydrocarbon source rocks, current data suggest a divergence between these two rock types at the high maturity end. In deep basin shale gas, reversals or rollovers in molecular and isotopic compositions are increasingly reported in what is effectively a closed shale system as opposed to the relative openness in coal measure environments. Detailed geochemical studies of coal bed and shale gas and related production waters are essential to determine not only gas origins but also the dominant methanogenic pathway in the case of microbial gases.

Controls of coal fabric on coalbed gas production and compositional shift in both field production and canister desorption tests  

SciTech Connect (OSTI)

The production rates of coalbed gas wells commonly vary significantly, even in the same field with similar reservoir permeability and gas content. The compositional variation in produced gas is also not everywhere predictable, although in most fields produced gas becomes progressively enriched in CO, through the production life of a reservoir, such as parts of the San Juan basin. In contrast, it is generally observed that the ratio of CO{sub 2}:CH{sub 4} declines with time during field and laboratory desorption testing of coal cores. In this study, we investigate numerically the importance of coal fabric, namely cleat spacing and aperture width, on the performance of coalbed gas wells and gas compositional shifts during production. Because of the cubic relationship between fracture permeability and fracture aperture width (and thus fracture porosity) for a given cleat permeability, the production profile of coal seams varies depending on whether the permeability is distributed among closely spaced fractures (cleat) with narrower apertures or more widely spaced fractures (cleat) with wider apertures. There is a lower fracture porosity for coal with widely spaced fractures than for coal with closely spaced fractures. Therefore, the relative permeability to gas increases more rapidly for coals with more widely spaced cleats as less dewatering from fractures is required, assuming that the fractures are initially water saturated. The enrichment of CO{sub 2} in the production gas with time occurs because of the stronger adsorption of coals for CO{sub 2} than CH{sub 4}. However, during desorption of coal cores, CO{sub 2} desorbs more rapidly than methane because desorption rate is governed more by diffusion than by sorption affinity, and CO{sub 2} has much higher effective diffusivity in microporous coals than CH{sub 4}.

Petrochemicals from oil, natural gas, coal and biomass: Production costs in 2030–2050  

Science Journals Connector (OSTI)

Methane, coal and biomass are being considered as alternatives to crude oil for the production of basic petrochemicals, such as light olefins. This paper is a study on the production costs of 24 process routes utilizing these primary energy sources. A wide range of projected energy prices in 2030–2050 found in the open literature is used. The basis for comparison is the production cost per t of high value chemicals (HVCs or light olefin-value equivalent). A Monte Carlo method was used to estimate the ranking of production costs of all 24 routes with 10,000 trials of varying energy prices and CO2 emissions costs (assumed to be within $0–100/t CO2; the total CO2 emissions, or cradle-to-grave CO2 emissions, were considered). High energy prices in the first three quarter of 2008 were tested separately. The main findings are:• Production costs: while the production costs of crude oil- and natural gas-based routes are within $500–900/t HVCs, those of coal- and biomass-based routes are mostly within $400–800/t HVCs. Production costs of coal- and biomass-based routes are in general quite similar while in some cases the difference is significant. Among the top seven most expensive routes, six are oil- and gas-based routes. Among the top seven least expensive routes, six are coal and biomass routes. • CO2 emissions costs: the effect of CO2 emissions costs was found to be strong on the coal-based routes and also quite significant on the biomass-based routes. However, the effect on oil- and gas-based routes is found to be small or relatively moderate. • Energy prices in 2008: most of the coal-based routes and biomass-based routes (particularly sugar cane) still have much lower production costs than the oil- and gas-based routes (even if international freight costs are included). To ensure the reduction of CO2 emissions in the long-term, we suggest that policies for the petrochemicals industry focus on stimulating the use of biomass as well as carbon capture and storage features for coal-based routes.

Porosity of coal and shale: Insights from gas adsorption and SANS/USANS techniques  

SciTech Connect (OSTI)

Two Pennsylvanian coal samples (Spr326 and Spr879-IN1) and two Upper Devonian-Mississippian shale samples (MM1 and MM3) from the Illinois Basin were studied with regard to their porosity and pore accessibility. Shale samples are early mature stage as indicated by vitrinite reflectance (R{sub o}) values of 0.55% for MM1 and 0.62% for MM3. The coal samples studied are of comparable maturity to the shale samples, having vitrinite reflectance of 0.52% (Spr326) and 0.62% (Spr879-IN1). Gas (N{sub 2} and CO{sub 2}) adsorption and small-angle and ultrasmall-angle neutron scattering techniques (SANS/USANS) were used to understand differences in the porosity characteristics of the samples. The results demonstrate that there is a major difference in mesopore (2-50 nm) size distribution between the coal and shale samples, while there was a close similarity in micropore (<2 nm) size distribution. Micropore and mesopore volumes correlate with organic matter content in the samples. Accessibility of pores in coal is pore-size specific and can vary significantly between coal samples; also, higher accessibility corresponds to higher adsorption capacity. Accessibility of pores in shale samples is low.

Enhancing the use of coals by gas reburning-sorbent injection  

SciTech Connect (OSTI)

Clean Coal Technology implies the use of coal in an environmentally acceptable manner. Coal combustion results in the emission of two types of acid rain precursors: oxides of sulfur (sox) and oxides of nitrogen (NO[sub x]). This Clean Coal Technology project will demonstrate a combination of two developed technologies to reduce both NO[sub x] and SO[sub x] emissions. Gas reburning and calcium based dry sorbent injection. The demonstrations will be conducted on two pre-NSPS utility boilers representative of the US boilers which contribute significantly to the inventory of acid rain precursor emissions. Gas reburning is a combustion modification technique that consists of firing 80--85 percent of the fuel (corresponding to the total heat release) in the lower furnace. Reduction of NO[sub x] to molecular nitrogen (N[sub 2]) is accomplished via the downstream injection of the remaining fuel requirement in the form of natural gas (which also reduces the total SO[sub x] emissions). In a third stage, burnout air is injected at lower temperatures in the upper furnace to complete the combustion process without generating significant additional NO[sub x]. Dry sorbent injection consists of injecting calcium based sorbents (such as limestone, dolomite, or hydrated lime) into the combustion products. For sulfation of the sorbent to CaSO[sub 4], an injection temperature of about 1230[degrees]C is optimum, but calcium-sulfur reactions can also take place at lower temperatures. Thus, the sorbent may be injected at different locations, such as with the burnout air, at the exit from the superheater, or into the ducting downstream of the air heater with H[sub 2]O added for humidification. The specific goal of this project is to demonstrate NO[sub x] and SO[sub x] emission reductions of 60 percent and 50 percent, respectively, on two coal fired utility boilers having the design characteristics mentioned above.

Development status of coal-fired gas heaters for Brayton-cycle cogeneration systems  

SciTech Connect (OSTI)

Under contract from the Department of Energy, Rocketdyne is developing the technology of coal-fired gas heaters for utilization in Brayton-cycle cogeneration systems. The program encompasses both atmospheric fluidized bed and pulverized coal combustion systems; and it is directed toward the development of gas heater systems capable of delivering high pressure air or helium at 1550 F, when employing metallic heat exchangers, and 1750 F, when employing ceramic heat exchangers. This paper reports on the development status of the program, with discussions of the completed ''screening'' corrosion/erosion tests of candidate heat exchanger materials, a description and summary of the operating experience with the 6- by 6-foot AFB test facility and a projection of the potential for relatively near term commercialization of such heater systems.

Permeability changes in coal resulting from gas desorption  

SciTech Connect (OSTI)

A high pressure chamber with a microbalance inside was designed and constructed for the purpose of measuring weight changes due to gas sorption at increasing pressure steps from 0 to 1000 psig. The raw weight changes recorded during the experiments had to be corrected for buoyancy and sample swelling. As the pressure in the balance chamber increases, the buoyancy forces tend to increase. The data were corrected and examined on the basis of five different sets of assumptions. At high pressures gas volumes measured have to be corrected for compressibility. The experimental data was analysed using five cases. The different cases were developed with certain assumptions. The five cases and the equations involved in each of them are discussed here.

Assessment of fuel-cycle energy use and greenhouse gas emissions for Fischer-Tropsch diesel from coal and cellulosic biomass.  

SciTech Connect (OSTI)

This study expands and uses the GREET (Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation) model to assess the effects of carbon capture and storage (CCS) technology and cellulosic biomass and coal cofeeding in Fischer-Tropsch (FT) plants on energy use and greenhouse gas (GHG) emissions of FT diesel (FTD). To demonstrate the influence of the coproduct credit methods on FTD life-cycle analysis (LCA) results, two allocation methods based on the energy value and the market revenue of different products and a hybrid method are employed. With the energy-based allocation method, fossil energy use of FTD is less than that of petroleum diesel, and GHG emissions of FTD could be close to zero or even less than zero with CCS when forest residue accounts for 55% or more of the total dry mass input to FTD plants. Without CCS, GHG emissions are reduced to a level equivalent to that from petroleum diesel plants when forest residue accounts for 61% of the total dry mass input. Moreover, we show that coproduct method selection is crucial for LCA results of FTD when a large amount of coproducts is produced.

Comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry of coal liquids produced during a coal liquefaction process  

SciTech Connect (OSTI)

Comprehensive two-dimensional gas chromatography (GC) coupled to time-of-flight mass spectrometry (MS) has been applied to the analysis of coal-derived liquids from the former British Coal Point-of-Ayr coal liquefaction plant. The feed to the hydrocracker and the resulting product were analyzed. The results refer almost exclusively to the plant-derived recycle solvent, known as the liquefaction solvent; the molecular mass range of the GC does not exceed that of the solvent. The method allows for the resolution of the numerous structural isomers of tetralin and methyl indan, one pair of hydrogen-donor (necessary for the dissolution of coal) and isomeric nondonor (that reduce the hydrogen donors) components of the recycle solvent. In addition, the n-alkanes that concentrate in the recycle solvent are easily observed in comparison with the results from one-dimensional GC-MS. 24 refs., 6 figs., 1 tab.

Investigation on Life-cycle Cost of Coal-based Synthetic Natural Gas (SNG)  

Science Journals Connector (OSTI)

Abstract Coal-based synthetic natural gas (SNG) is considered to be a promising alternative of clean energy, especially for urban uses, to response to the insufficient supply of natural gas in China, In this paper, life cycle costing is conducted for SNG in three main urban applications: heating boiler use, residential use, and transit bus use, respectively. The results show that the SNG is competitive for residential use, while it is not as cost- effective as expected when used for heating boiler use or transit bus use. Major shortcoming of SNG is from the large environmental emissions in the production stage.

PRELIMINARY CHARACTERIZATION OF CO2 SEPARATION AND STORAGE PROPERTIES OF COAL GAS RESERVOIRS  

SciTech Connect (OSTI)

An attractive alternative of sequestering CO{sub 2} is to inject it into coalbed methane reservoirs, particularly since it has been shown to enhance the production of methane during near depletion stages. The basis for enhanced coalbed methane recovery and simultaneous sequestration of carbon dioxide in deep coals is the preferential sorption property of coal, with its affinity for carbon dioxide being significantly higher than that for methane. Yet, the sorption behavior of coal under competitive sorptive environment is not fully understood. Hence, the original objective of this research study was to carry out a laboratory study to investigate the effect of studying the sorption behavior of coal in the presence of multiple gases, primarily methane, CO{sub 2} and nitrogen, in order to understand the mechanisms involved in displacement of methane and its movement in coal. This had to be modified slightly since the PVT property of gas mixtures is still not well understood, and any laboratory work in the area of sorption of gases requires a definite equation of state to calculate the volumes of different gases in free and adsorbed forms. This research study started with establishing gas adsorption isotherms for pure methane and CO{sub 2}. The standard gas expansion technique based on volumetric analysis was used for the experimental work with the additional feature of incorporating a gas chromatograph for analysis of gas composition. The results were analyzed first using the Langmuir theory. As expected, the Langmuir analysis indicated that CO{sub 2} is more than three times as sorptive as methane. This was followed by carrying out a partial desorption isotherm for methane, and then injecting CO{sub 2} to displace methane. The results indicated that CO{sub 2} injection at low pressure displaced all of the sorbed methane, even when the total pressure continued to be high. However, the displacement appeared to be occurring due to a combination of the preferential sorption property of coal and reduction in the partial pressure of methane. As a final step, the Extended Langmuir (EL) model was used to model the coal-methane-CO{sub 2} binary adsorption system. The EL model was found to be very accurate in predicting adsorption of CO{sub 2}, but not so in predicting desorption of methane. The selectivity of CO{sub 2} over methane was calculated to be 4.3:1. This is, of course, not in very good agreement with the measured values which showed the ratio to be 3.5:1. However, the measured results are in good agreement with the field observation at one of the CO{sub 2} injection sites. Based on the findings of this study, it was concluded that low pressure injection of CO{sub 2} can be fairly effective in displacing methane in coalbed reservoirs although this might be difficult to achieve in field conditions. Furthermore, the displacement of methane appears to be not only due to the preferential sorption of methane, but reduction in partial pressure as well. Hence, using a highly adsorbing gas, such as CO{sub 2}, has the advantages of inert gas stripping and non-mixing since the injected gas does not mix with the recovered methane.

Next Generation Pressurized Oxy-Coal Combustion: High Efficiency and No Flue Gas Recirculation  

SciTech Connect (OSTI)

The Gas Technology Institute (GTI) has developed a pressurized oxy-coal fired molten bed boiler (MBB) concept, in which coal and oxygen are fired directly into a bed of molten coal slag through burners located on the bottom of the boiler and fired upward. Circulation of heat by the molten slag eliminates the need for a flue gas recirculation loop and provides excellent heat transfer to steam tubes in the boiler walls. Advantages of the MBB technology over other boilers include higher efficiency (from eliminating flue gas recirculation), a smaller and less expensive boiler, modular design leading to direct scalability, decreased fines carryover and handling costs, smaller exhaust duct size, and smaller emissions control equipment sizes. The objective of this project was to conduct techno-economic analyses and an engineering design of the MBB project and to support this work with thermodynamic analyses and oxy-coal burner testing. Techno-economic analyses of GTI’s pressurized oxy-coal fired MBB technology found that the overall plant with compressed CO2 has an efficiency of 31.6%. This is a significant increase over calculated 29.2% efficiency of first generation oxy-coal plants. Cost of electricity (COE) for the pressurized MBB supercritical steam power plant with CO2 capture and compression was calculated to be 134% of the COE for an air-coal supercritical steam power plant with no CO2 capture. This compares positively with a calculated COE for first generation oxy-coal supercritical steam power plants with CO2 capture and compression of 164%. The COE for the MBB power plant is found to meet the U.S. Department of Energy (DOE) target of 135%, before any plant optimization. The MBB power plant was also determined to be simpler than other oxy-coal power plants with a 17% lower capital cost. No other known combustion technology can produce higher efficiencies or lower COE when CO2 capture and compression are included. A thermodynamic enthalpy and exergy analysis found a number of modifications and adjustments that could provide higher efficiency and better use of available work. Conclusions from this analysis will help guide the analyses and CFD modeling in future process development. The MBB technology has the potential to be a disruptive technology that will enable coal combustion power plants to be built and operated in a cost effective way, cleanly with no carbon dioxide emissions. A large amount of work is needed to quantify and confirm the great promise of the MBB technology. A Phase 2 proposal was submitted to DOE and other sponsors to address the most critical MBB process technical gaps. The Phase 2 proposal was not accepted for current DOE support.

Volumetric strain associated with methane desorption and its impact on coalbed gas production from deep coal seams  

SciTech Connect (OSTI)

For deep coal seams, significant reservoir pressure drawdown is required to promote gas desorption because of the Langmuir-type isotherm that typifies coals. Hence, a large permeability decline may occur because of pressure drawdown and the resulting increase in effective stress, depending on coal properties and the stress field during production. However, the permeability decline can potentially be offset by the permeability enhancement caused by the matrix shrinkage associated with methane desorption. The predictability of varying permeability is critical for coalbed gas exploration and production-well management. We have investigated quantitatively the effects of reservoir pressure and sorption-induced volumetric strain on coal-seam permeability with constraints from the adsorption isotherm and associated volumetric strain measured on a Cretaceous Mesaverde Group coal (Piceance basin) and derived a stress-dependent permeability model. Our results suggest that the favorable coal properties that can result in less permeability reduction during earlier production and an earlier strong permeability rebound (increase in permeability caused by coal shrinkage) with methane desorption include (1) large bulk or Young's modulus; (2) large adsorption or Langmuir volume; (3) high Langmuir pressure; (4) high initial permeability and dense cleat spacing; and (5) low initial reservoir pressure and high in-situ gas content. Permeability variation with gas production is further dependent on the orientation of the coal seam, the reservoir stress field, and the cleat structure. Well completion with injection of N2 and displacement of CH{sub 4} only results in short-term enhancement of permeability and does not promote the overall gas production for the coal studied.

Hot coal gas desulfurization with manganese-based sorbents. Final report, September 1992--December 1994  

SciTech Connect (OSTI)

The focus of much current work being performed by the Morgantown Energy Technology Center (METC) of the Department of Energy on hot coal-derived fuel gas desulfurization is in the use of zinc-based sorbents. METC has shown interest in formulating and testing manganese-based pellets as alternative effective sulfur sorbents in the 700 to 1200{degree}C temperature range. To substantiate the potential superiority of Mn-based pellets, a systematic approach toward the evaluation of the desulfurizing power of single-metal sorbents is developed based on thermodynamic considerations. This novel procedure considered several metal-based sorbents and singled out manganese oxide as a prime candidate sorbent capable of being utilized under a wide temperature range, irrespective of the reducing power (determined by CO{sub 2}/CO ratio) of the fuel gas. Then, the thermodynamic feasibility of using Mn-based pellets for the removal of H{sub 2}S from hot-coal derived fuel gases, and the subsequent oxidative regeneration of loaded (sulfided) pellets was established. It was concluded that MnO is the stable form of manganese for virtually all commercially available coal-derived fuel gases. In addition, the objective of reducing the H{sub 2}S concentration below 150 ppMv to satisfy the integrated gasification combined cycle system requirement was shown to be thermodynamically feasible. A novel process is developed for the manufacture of Mn-based spherical pellets which have the desired physical and chemical characteristics required.

Life Cycle Greenhouse Gas Emissions of Coal-Fired Electricity Generation: Systematic Review and Harmonization  

SciTech Connect (OSTI)

This systematic review and harmonization of life cycle assessments (LCAs) of utility-scale coal-fired electricity generation systems focuses on reducing variability and clarifying central tendencies in estimates of life cycle greenhouse gas (GHG) emissions. Screening 270 references for quality LCA methods, transparency, and completeness yielded 53 that reported 164 estimates of life cycle GHG emissions. These estimates for subcritical pulverized, integrated gasification combined cycle, fluidized bed, and supercritical pulverized coal combustion technologies vary from 675 to 1,689 grams CO{sub 2}-equivalent per kilowatt-hour (g CO{sub 2}-eq/kWh) (interquartile range [IQR]= 890-1,130 g CO{sub 2}-eq/kWh; median = 1,001) leading to confusion over reasonable estimates of life cycle GHG emissions from coal-fired electricity generation. By adjusting published estimates to common gross system boundaries and consistent values for key operational input parameters (most importantly, combustion carbon dioxide emission factor [CEF]), the meta-analytical process called harmonization clarifies the existing literature in ways useful for decision makers and analysts by significantly reducing the variability of estimates ({approx}53% in IQR magnitude) while maintaining a nearly constant central tendency ({approx}2.2% in median). Life cycle GHG emissions of a specific power plant depend on many factors and can differ from the generic estimates generated by the harmonization approach, but the tightness of distribution of harmonized estimates across several key coal combustion technologies implies, for some purposes, first-order estimates of life cycle GHG emissions could be based on knowledge of the technology type, coal mine emissions, thermal efficiency, and CEF alone without requiring full LCAs. Areas where new research is necessary to ensure accuracy are also discussed.

Greenhouse gas emissions reduction in China by cleaner coal technology towards 2020  

Science Journals Connector (OSTI)

Abstract The Chinese energy system, a major CO2 emitter, relies heavily on fossil fuels, especially coal. Coal will continue to play a major role in the new installed power generation capacity in the future, which will cause unavoidable environmental problems. Clean coal technologies (CCTs) are essential for emissions reduction in the power sector. In general, \\{CCTs\\} cover coal upgrading, efficiency improvements, advanced technologies and zero emissions technologies. Besides these, \\{CCTs\\} also include other emissions reduction technologies and comprehensive utilization technologies in China. This paper review the complete life cycle modeling of CCTs. The advanced technologies include super-critical (super-C), ultra super-critical (USC) and integrated gasification combined cycle (IGCC). The results show that the higher efficiency technologies have lower potential impacts. Compared with the average level of power generation technology, CO2 emissions reduction is 6.4% for super-C, 37.4% for USC and 61.5% for IGCC. Four coal power scenarios are developed based on the assumption of potential investment power for \\{CCTs\\} in 2020, which are super-C, USC, USC and old low efficiency generation substitution by USC, IGCC and carbon capture and storage (CCS). The CO2 emissions intensity is 1.93 kg/kWh for super-C, 1.69 kg/kWh for USC, 1.59 kg/kWh for USC + replacement and 1.29 kg/kWh for IGCC + CCS. The CO2 emissions intensity was 1.95 kg/kWh in 2010, which had decreased 5.5% compared with the level in 2005. The energy structure is continuously being improved and optimized. The potential carbon reduction will be limited in the power system in 2020 by current commercial \\{CCTs\\} with the generation efficiency increase. The most impressive technology is IGCC with CCS which enables greenhouse gas reduction of 37.6% compared with the level in 2005.

Optimizing heat integration in a flexible coal–natural gas power station with CO2 capture  

Science Journals Connector (OSTI)

Abstract Computational optimization is used to simultaneously determine the design and planned operating profile of a flexible coal–natural gas power station with CO2 capture, under a CO2 emission performance standard. The facility consists of a coal-fired power station undergoing retrofit with CO2 capture. The CO2 capture energy demand is provided by a specially designed combined cycle gas turbine (CCGT). The heat recovery steam generator (HRSG) component of the CCGT is modeled and optimized in detail, with explicit treatment of the discrete aspects of the HRSG configuration, including the number and sequential arrangement of HRSG internal components. Variable facility operations are represented by discrete operating modes selected based on the electricity price–duration curve. Two objectives, the minimization of capital requirement and the maximization of net present value, are considered in a bi-objective mixed-integer nonlinear programming formulation. Pareto frontiers, which define the optimal tradeoffs between these two objectives, are generated for six scenarios constructed from recent historical data from West Texas, the United Kingdom, and India. For a 440 MW coal plant in a scenario based on 2011 West Texas data, the minimum effective net present cost required for the retrofit (which meets the CO2 emission performance standard) varies from $278 to 383 million, and the minimum total capital investment requirement ranges from $346 to 517 million. The variations in these optimized values correspond to the range of the Pareto frontier within the bounds of the problem. The net present cost of the retrofit is less than the present value of the existing coal plant, $476 million, indicating that a retrofit is preferred over decommissioning. In the case of very low energy prices, however, decommissioning is shown to be the preferred option. The UK and India scenarios demonstrate that optimal designs can vary greatly depending upon location-specific economic conditions.

Comparative life-cycle air emissions of coal, domestic natural gas, LNG, and SNG for electricity generation  

SciTech Connect (OSTI)

The U.S. Department of Energy (DOE) estimates that in the coming decades the United States' natural gas (NG) demand for electricity generation will increase. Estimates also suggest that NG supply will increasingly come from imported liquefied natural gas (LNG). Additional supplies of NG could come domestically from the production of synthetic natural gas (SNG) via coal gasification-methanation. The objective of this study is to compare greenhouse gas (GHG), SOx, and NOx life-cycle emissions of electricity generated with NG/LNG/SNG and coal. This life-cycle comparison of air emissions from different fuels can help us better understand the advantages and disadvantages of using coal versus globally sourced NG for electricity generation. Our estimates suggest that with the current fleet of power plants, a mix of domestic NG, LNG, and SNG would have lower GHG emissions than coal. If advanced technologies with carbon capture and sequestration (CCS) are used, however, coal and a mix of domestic NG, LNG, and SNG would have very similar life-cycle GHG emissions. For SOx and NOx we find there are significant emissions in the upstream stages of the NG/LNG life-cycles, which contribute to a larger range in SOx and NOx emissions for NG/LNG than for coal and SNG. 38 refs., 3 figs., 2 tabs.

How international oil and gas companies respond to local content policies in petroleum-producing developing countries: A narrative enquiry  

Science Journals Connector (OSTI)

Abstract This paper uses narrative analysis to critically examine the business practices used by five international oil and gas companies (IOCs) (Chevron, ExxonMobil, Shell, BP and Total) to respond to local content policies in petroleum-producing developing countries (Nigeria, Angola, Venezuela, Kazakhstan, Brazil, Indonesia, Yemen and Indonesia) during the period 2000–2012. The business practices include the formulation of local content strategies that are implemented through programmes and initiatives aimed at developing and using host country suppliers and workforce. Such practices and the narratives used to communicate them implicitly reflect the context in which the effectiveness of local content policies on economic development can be assessed. By comparing and contrasting the narratives across the five \\{IOCs\\} in relation to the wider literature, four emergent narrative strategies justifying the business practices of \\{IOCs\\} are identified and discussed. They include: (1) direct engagement to renegotiate local content requirements with governments, (2) legal compliance framework, (3) the business case for local content strategies, and (4) corporate social responsibility (CSR) initiatives. The conclusion considers the policy implications of these findings for local content development in petroleum-producing developing countries.

With this cofiring configuration, the improved heat distribution and mixing with the stoker combustion products can give reduced opacity, reduced emissions of particulate, NO{sub x} and SO{sub 2}, improved carbon burnout and lower overall ash, reduced excess air, faster load response, cleaner and quicker lightoffs, improved turndown at both lower and upper capacity limits, and improved performance with problematic coals. To develop and validate the cofiring technology, three cofire field experiments have been conducted. A 165,000 lb/hr spreader stoker and mass feed chain grate stokers rated at 40,000 and 75,000 lb/hr have been retrofit with gas burners and tested in the field. The two larger units used dual, opposed burners, while the smaller unit was retrofit with a single burner. With the spreader stoker, the primary benefits of gas cofire was reduction in opacity episodes with coal quality variability and recovery of lost derate. With the larger chain grate unit, the primary benefit was reduction of NO{sub x} and SO{sub 2} to within Title V limits and elimination of opacity episodes during startup and load swings. With the smaller chain grate, the primary benefit was ability to operate at low loads without unacceptable opacity excursions which had previously required a backup boiler. In all cases, the economics justified the capital burner system retrofit cost and incremental fuel costs.

Erosion-corrosion modelling of gas turbine materials for coal-fired combined cycle power generation  

Science Journals Connector (OSTI)

The development of coal-fired combined cycle power generation systems is receiving considerable worldwide interest. The successful development and commercialisation of these new systems require that all the component parts are manufactured from appropriate materials and that these materials give predictable in-service performance. Corrosion and erosion-corrosion, resulting from coal derived particulates, deposition and gaseous species, have been identified as potential life limiting factors for these systems. Models to predict these modes of materials degradation are under active development. This paper outlines the development and testing of models suitable for use in gas turbine environments. The complexity of the corrosion processes means that an empirical approach to model development is required whereas a more mechanistic approach can be applied to erosion processes. For hot corrosion conditions, statistically based corrosion models have been produced using laboratory tests for two coatings and a base alloy at typical type I and type II hot corrosion temperatures (900 and 700°C). These models use the parameters of alkali sulphate deposition flux and \\{SOx\\} partial pressure (at each temperature and for set \\{HCl\\} partial pressures), to predict the rate of the most likely localised damage associated with hot corrosion reactions. For erosion-corrosion modelling, a series of laboratory tests have been carried out to investigate erosion behaviour in corrosive conditions appropriate to coal-fired gas turbines. Materials performance data have been obtained from samples located in the hot gas path of the Grimethorpe PFBC pilot plant, under well characterised conditions, for testing the corrosion and erosion-corrosion models. The models successfully predict the materials damage observed in the pilot plant environments.

High temperature alkali corrosion of ceramics in coal gas. Quarterly progress report No. 3, March 1, 1992--May 31, 1992  

SciTech Connect (OSTI)

High temperature alkali corrosion has been known to cause premature failure of ceramic components used in advanced high temperature coal combustion systems such as coal gasification and clean-up, coal fired gas turbines, and high efficiency heat engines. The objective of this research is to systematically evaluate the alkali corrosion resistance of the most commonly used structural ceramics including silicon carbide, silicon nitride, cordierite, mullite, alumina, aluminum titanate, zirconia, and fireclay glass. The study consists of identification of the alkali reaction products (phase equilibria) and the kinetics of the alkali reactions as a function of temperature and time.

Advanced Acid Gas Separation Technology for the Utilization of Low Rank Coals  

SciTech Connect (OSTI)

Air Products has developed a potentially ground-breaking technology – Sour Pressure Swing Adsorption (PSA) – to replace the solvent-based acid gas removal (AGR) systems currently employed to separate sulfur containing species, along with CO{sub 2} and other impurities, from gasifier syngas streams. The Sour PSA technology is based on adsorption processes that utilize pressure swing or temperature swing regeneration methods. Sour PSA technology has already been shown with higher rank coals to provide a significant reduction in the cost of CO{sub 2} capture for power generation, which should translate to a reduction in cost of electricity (COE), compared to baseline CO{sub 2} capture plant design. The objective of this project is to test the performance and capability of the adsorbents in handling tar and other impurities using a gaseous mixture generated from the gasification of lower rank, lignite coal. The results of this testing are used to generate a high-level pilot process design, and to prepare a techno-economic assessment evaluating the applicability of the technology to plants utilizing these coals.

Effect of steam partial pressure on gasification rate and gas composition of product gas from catalytic steam gasification of HyperCoal  

SciTech Connect (OSTI)

HyperCoal was produced from coal by a solvent extraction method. The effect of the partial pressure of steam on the gasification rate and gas composition at temperatures of 600, 650, 700, and 750{sup o}C was examined. The gasification rate decreased with decreasing steam partial pressure. The reaction order with respect to steam partial pressure was between 0.2 and 0.5. The activation energy for the K{sub 2}CO{sub 3}-catalyzed HyperCoal gasification was independent of the steam partial pressure and was about 108 kJ/mol. The gas composition changed with steam partial pressure and H{sub 2} and CO{sub 2} decreased and CO increased with decreasing steam partial pressure. By changing the partial pressure of the steam, the H{sub 2}/CO ratio of the synthesis gas can be controlled. 18 refs., 7 figs., 2 tabs.

Enahancing the Use of Coals by Gas Reburning - Sorbent Injection Volume 5 - Guideline Manual  

SciTech Connect (OSTI)

The purpose of the Guideline Manual is to provide recommendations for the application of combined gas reburning-sorbent injection (GR-SI) technologies to pre-NSPS boilers. The manual includes design recommendations, performance predictions, economic projections and comparisons with competing technologies. The report also includes an assessment of boiler impacts. Two full-scale demonstrations of gas reburning-sorbent injection form the basis of the Guideline Manual. Under the U.S. Department of Energy's Clean Coal Technology Program (Round 1), a project was completed to demonstrate control of boiler emissions that comprise acid rain precursors, specifically oxides of nitrogen (NOX) and sulfur dioxide (S02). Other project sponsors were the Gas Research Institute and the Illinois State Department of Commerce and Community Affairs. The project involved demonstrating the combined use of Gas Reburning and Sorbent Injection (GR-SI) to assess the air emissions reduction potential of these technologies.. Three potential coal-fired utility boiler host sites were evaluated: Illinois Power's tangentially-fired 71 MWe (net) Hennepin Unit W, City Water Light and Power's cyclone- fired 33 MWe (gross) Lakeside Unit #7, and Central Illinois Light Company's wall-fired 117 MWe (net) Edwards Unit #1. Commercial demonstrations were completed on the Hennepin and Lakeside Units. The Edwards Unit was removed from consideration for a site demonstration due to retrofit cost considerations. Gas Reburning (GR) controls air emissions of NOX. Natural gas is introduced into the furnace hot flue gas creating a reducing reburning zone to convert NOX to diatomic nitrogen (N,). Overfire air is injected into the furnace above the reburning zone to complete the combustion of the reducing (fuel) gases created in the reburning zone. Sorbent Injection (S1) consists of the injection of dry, calcium-based sorbents into furnace hot flue gas to achieve S02 capture. At each site where the techno!o@es were to be demonstrated, petiormance goals were set to achieve air emission reductions of 60 percent for NO. and 50 percent for SO2. These performance goals were exceeded during long term demonstration testing. For the tangentially fired unit, NOX emissions were reduced by 67.2% and S02 emissions by 52.6%. For the cyclone-fired unit, NOX emissions were reduced by 62.9% and SOZ emissions by 57.9%.

Enhancing the use of coals by gas reburning-sorbent injection  

SciTech Connect (OSTI)

The objective of this project is to evaluate and demonstrate a cost effective emission control technology for acid rain precursors, oxides of nitrogen (NO[sub x]) and sulfur (SO[sub x]) on two coal fired utility boilers in Illinois. The units selected are representative of pre-NSPS design practices: tangential and cyclone fired. Work on a third unit, wall fired, has been stopped because of funding limitations. The specific objectives are to demonstrate reductions of 60 percent in NO[sub x] and 50 percent in SO[sub x] emissions, by a combination of two developed technologies, gas reburning (GR) and sorbent injection (SI). With GR, about 80--85 percent of the coal fuel is fired in the primary combustion zone. The balance of the fuel is added downstream as natural gas to create a slightly fuel rich environment in which NO[sub x] is converted to N[sub 2]. The combustion process is completed by overfire air addition. So[sub x] emissions are reduced by injecting dry sorbents (usually calcium based) into the upper furnace. The sorbents trap SO[sub x] as solid sulfates that are collected in the particulate control device. This project is conducted in three phases at each site: (1) Design and Permitting; (2) Construction and Startup; and, (3) Operation, Data Collection, Reporting and Disposition. Technology transfer to industry is accomplished through the formation of an industry panel.

CO2 SEQUESTRATION POTENTIAL OF TEXAS LOW-RANK COALS  

SciTech Connect (OSTI)

The objectives of this project are to evaluate the feasibility of carbon dioxide (CO{sub 2}) sequestration in Texas low-rank coals and to determine the potential for enhanced coalbed methane (CBM) recovery as an added benefit of sequestration. The main tasks for this reporting period were to correlate well logs and refine coal property maps, evaluate methane content and gas composition of Wilcox Group coals, and initiate discussions concerning collection of additional, essential data with Anadarko. To assess the volume of CO{sub 2} that may be sequestered and volume of methane that can be produced in the vicinity of the proposed Sam Seymour sequestration site, we used approximately 200 additional wells logs from Anadarko Petroleum Corp. to correlate and map coal properties of the 3 coal-bearing intervals of Wilcox group. Among the maps we are making are maps of the number of coal beds, number of coal beds greater than 5 ft thick, and cumulative coal thickness for each coal interval. This stratigraphic analysis validates the presence of abundant coal for CO{sub 2} sequestration in the Wilcox Group in the vicinity of Sam Seymour power plant. A typical wellbore in this region may penetrate 20 to 40 coal beds with cumulative coal thickness between 80 and 110 ft. Gas desorption analyses of approximately 75 coal samples from the 3 Wilcox coal intervals indicate that average methane content of Wilcox coals in this area ranges between 216 and 276 scf/t, basinward of the freshwater boundary indicated on a regional hydrologic map. Vitrinite reflectance data indicate that Wilcox coals are thermally immature for gas generation in this area. Minor amounts of biogenic gas may be present, basinward of the freshwater line, but we infer that most of the Wilcox coalbed gas in the deep coal beds is migrated thermogenic gas. Analysis based on limited data suggest that sites for CO{sub 2} sequestration and enhanced coalbed gas recovery should be located basinward of the Wilcox freshwater contour, where methane content is high and the freshwater aquifer can be avoided.

Enhancing the use of coals by gas reburning-sorbent injection. Quarterly report No. 6, October 1--December 31, 1991  

SciTech Connect (OSTI)

Clean Coal Technology implies the use of coal in an environmentally acceptable manner. Coal combustion results in the emission of two types of acid rain precursors: oxides of sulfur (SO{sub x}) and oxides of nitrogen (NO{sub x}). This Clean Coal Technology project will demonstrate a combination of two developed technologies to reduce both NO{sub x} and SO{sub x} emissions: gas reburning and calcium based dry sorbent injection. The demonstrations will be conducted on two pre-NSPS utility boilers representative of the US boilers which contribute significantly to the inventory of acid rain precursor emissions: tangentially and cyclone fired units. Because of cost growth and lack of available funding, no further work has been done after Phase 1 at site B; the wall fired unit.

Enhancing the use of coals by gas reburning-sorbent injection

This Clean Coal Technology project will demonstrate a combination of two developed technologies to reduce both NO[sub x] and SO[sub x] emissions: gas reburning and calcium based dry sorbent injection. The demonstrations will be conducted on two pre-NSPS utility boilers representative of the US boilers which contribute significantly to the inventory of acid rain precursor emissions: tangentially and cyclone fired units. Gas reburning is a combustion modification technique that consists of firing 80--85 percent of the fuel (corresponding to the total heat release) in the lower furnace. Reduction of NO[sub x] to molecular nitrogen (N[sub 2]) is accomplished via the downstream injection of the remaining fuel requirement in the form of natural gas (which also reduces the total SO[sub x] emissions). In a third stage, burnout air is injected at lower temperatures in the upper furnace to complete the combustion process without generating significant additional NO[sub x]. Dry sorbent injection consists of injecting calcium based sorbents (such as limestone, dolomite, or hydrated lime) into the combustion products. For sulfation of the sorbent to CaSO[sub 4], an injection temperature of about 1230[degrees]C is optimum, but calcium-sulfur reactions can also take place at lower temperatures. Thus, the sorbent may be injected at different locations, such as with the burnout air, at the exit from the superheater, or into the ducting downstream of the air heater with H[sub 2]0 added for humidification. The calcium sulfate or sulfite products are collected together with unreacted sorbent fly ash by the electrostatic precipitator. The specific goal of this project is to demonstrate NO[sub x] and SO[sub x] emission reductions of 60 percent and 50 percent, respectively, on two coal fired utility boilers having the design characteristics mentioned above.

On the definition of exergy efficiencies for petroleum systems: Application to offshore oil and gas processing  

Science Journals Connector (OSTI)

Abstract Exergy-based efficiencies are measures of the thermodynamic perfection of systems and processes. A meaningful formulation of these performance criteria for petroleum systems is difficult because of (i) the high chemical exergy of hydrocarbons, (ii) the large variety of chemical components, and (iii) the differences in operating conditions between facilities. This work focuses on offshore processing plants, considering four oil platforms that differ by their working conditions and designs. Several approaches from the scientific literature for similar processes are presented and applied to the four cases. They showed a low sensitivity to performance improvements, gave inconsistent results, or favoured facilities operating under certain conditions. We suggest an alternative formulation, called the component-by-component exergy efficiency, which builds on the decomposition of the exergy flows at the level of the chemical compounds. It allows therefore for sound comparisons of separation systems, while it successfully evaluates their theoretical improvement potentials. The platform displaying the lowest efficiency (1.7%) is characterised by little pumping and compression works, at the opposite of the one displaying the highest performance (29.6%). A more realistic measure of the technical potential for improving these systems can be carried out by splitting further the exergy destruction into its avoidable and unavoidable parts.

SNG Production from Coal: A Possible Solution to Energy Demand  

Science Journals Connector (OSTI)

Abstract In some areas of the world, natural gas demand cannot be fully satisfied either by domestic sources or foreign imports, while abundant coal resources are available. The conversion of coal to Substitute Natural Gas, SNG, by coal gasification and subsequent syngas methanation is one of the possible solutions to solve the problem. Foster Wheeler has developed a simple process for SNG production, named VESTA, utilizing catalysts from Clariant. The process concept has been proven by laboratory tests, and a demonstration unit will soon be completed. The VESTA process is very flexible and can handle syngas coming from several sources such as coal, biomass, petroleum coke and solid waste. In this paper our overview of the technology and its development status will be outlined.

Durable regenerable sorbent pellets for removal of hydrogen sulfide from coal gas  

DOE Patents [OSTI]

Pellets for removing hydrogen sulfide from a coal gasification stream at an elevated temperature are prepared in durable form usable over repeated cycles of absorption and regeneration. The pellets include a material reactive with hydrogen sulfide, in particular zinc oxide, a binder, and an inert material, in particular calcium sulfate (drierite), having a particle size substantially larger than other components of the pellets. A second inert material and a promoter may also be included. Preparation of the pellets may be carried out by dry, solid-state mixing of components, moistening the mixture, and agglomerating it into pellets, followed by drying and calcining. Pellet size is selected, depending on the type of reaction bed for which the pellets are intended. The use of inert material with a large particle size provides a stable pellet structure with increased porosity, enabling effective gas contact and prolonged mechanical durability.

The pellets include a material reactive with hydrogen sulfide, in particular zinc oxide, a binder, and an inert material, in particular calcium sulfate (drierite), having a particle size substantially larger than other components of the pellets. A second inert material and a promoter may also be included. Preparation of the pellets may be carried out by dry, solid-state mixing of components, moistening the mixture, and agglomerating it into pellets, followed by drying and calcining. Pellet size is selected, depending on the type of reaction bed for which the pellets are intended. The use of inert material with a large particle size provides a stable pellet structure with increased porosity, enabling effective gas contact and prolonged mechanical durability.

Gas separation by pressure swing adsorption for producing hydrogen from coal: Final report  

SciTech Connect (OSTI)

This project demonstrated the feasibility of producing high purity hydrogen from a coal gasification product gas mixture by Pressure Swing Adsorption (PSA) using a commercial 5A zeolite as the adsorbent. The major advantage of PSA over conventional hydrogen upgrading processes is associated with lower overall production costs. This is mainly due to the integration of PSA into H/sub 2/ production plants as a single unit operation by replacing the low temperature carbon monoxide shift, carbon dioxide wash and methanation steps. In this way, hydrogen production costs are typically reduced from 7 to 40%. A single bed PSA process was designed to simulate the various steps of commercial multibed PSA plants. A new and very important step, ''Vacuum Purge'', was also investigated. 45 refs., 38 figs., 50 tabs.

The economical production of alcohol fuels from coal-derived synthesis gas: Case studies, design, and economics  

SciTech Connect (OSTI)

This project is a combination of process simulation and catalyst development aimed at identifying the most economical method for converting coal to syngas to linear higher alcohols to be used as oxygenated fuel additives. There are two tasks. The goal of Task 1 is to discover, study, and evaluate novel heterogeneous catalytic systems for the production of oxygenated fuel enhancers from synthesis gas, and to explore, analytically and on the bench scale, novel reactor and process concepts for use in converting syngas to liquid fuel products. The goal of Task 2 is to simulate, by computer, energy efficient and economically efficient processes for converting coal to energy (fuel alcohols and/or power). The primary focus is to convert syngas to fuel alcohols. This report contains results from Task 2. The first step for Task 2 was to develop computer simulations of alternative coal to syngas to linear higher alcohol processes, to evaluate and compare the economics and energy efficiency of these alternative processes, and to make a preliminary determination as to the most attractive process configuration. A benefit of this approach is that simulations will be debugged and available for use when Task 1 results are available. Seven cases were developed using different gasifier technologies, different methods for altering the H{sub 2}/CO ratio of the syngas to the desired 1.1/1, and with the higher alcohol fuel additives as primary products and as by-products of a power generation facility. Texaco, Shell, and Lurgi gasifier designs were used to test gasifying coal. Steam reforming of natural gas, sour gas shift conversion, or pressure swing adsorption were used to alter the H{sub 2}/CO ratio of the syngas. In addition, a case using only natural gas was prepared to compare coal and natural gas as a source of syngas.

Advances of flue gas desulfurization technology for coal-fired boilers and strategies for sulfur dioxide pollution prevention in China  

SciTech Connect (OSTI)

Coal is one of the most important kinds of energy resources at the present time and in the immediate future in China. Sulfur dioxide resulting from combustion of coal is one of the principle pollutants in the air. Control of SO{sub 2} discharge is still a major challenge for environmental protection in developing China. In this paper, research, development and application of technology of flue gas desulfurization (FGD) for coal-fired boilers in China will be reviewed with emphasis on cost-effective technology, and the development trends of FGD technology, as well as the strategy for SO{sub 2} discharge control in China, will be analyzed. A practical technology for middle-small-sized boilers developed by the primary author and the field investigation results will also be presented. At present, there are four major kinds of FGD technologies that are practical to be applied in China for their cost-effectiveness and efficiency to middle-small-sized boilers. An important development trend of the FGD technology for middle-small-sized boilers for the next decade is improvement of the existing cost-effective wet-type FGD technology, and in the future it will be the development of dry-type FGD technology. For middle-sized generating boilers, the development direction of the FGD technology is the spraying and drying process. For large-sized generating boilers, the wet-type limestone-plaster process will still be applied in the immediate future, and dry-type FGD technologies, such as ammonia with electron beam irradiation, will be developed in the future. State strategies for the control of SO{sub 2} discharge will involve the development and popularization of efficient coal-fired devices, extension of gas coal and liquefied coal, spreading coal washing, and centralized heating systems.

DEVELOPMENT OF NOVEL CERAMIC NANOFILM-FIBER INTEGRATED OPTICAL SENSORS FOR RAPID DETECTION OF COAL DERIVED SYNTHESIS GAS  

SciTech Connect (OSTI)

The overall goal of this project is to conduct fundamental studies on advanced ceramic materials and fiber optic devices for developing new types of high temperature (>500{degree}C) fiber optic chemical sensors (FOCS) for monitoring fossil (mainly coal) and biomass derived gases in power plants. The primary technical objective is to investigate and demonstrate the nanocrystalline doped-ceramic thin film enabled FOCS that possess desired stability, sensitivity and selectivity for in-situ, rapid gas detection in the syngas streams from gasification and combustion flue gases. This report summarizes research works of two integrated parts: (1) development of metal oxide solid thin films as sensing materials for detection and measurement of important gas components relevant to the coal- and biomass-derived syngas and combustion gas streams at high temperatures; and (2) development of fiber optic devices that are potentially useful for constructing FOCS in combination with the solid oxide thin films identified in this program.

ADVANCED FLUE GAS CONDITIONING AS A RETROFIT UPGRADE TO ENHANCE PM COLLECTION FROM COAL-FIRED ELECTRIC UTILITY BOILERS  

SciTech Connect (OSTI)

The U.S. Department of Energy and ADA Environmental Solutions are engaged in a project to develop commercial flue gas conditioning additives. The objective is to develop conditioning agents that can help improve particulate control performance of smaller or under-sized electrostatic precipitators on utility coal-fired boilers. The new chemicals will be used to control both the electrical resistivity and the adhesion or cohesivity of the fly ash. There is a need to provide cost-effective and safer alternatives to traditional flue gas conditioning with SO{sub 3} and ammonia. During this reporting quarter, installation of a liquid flue gas conditioning system was completed at the American Electric Power Conesville Plant, Unit 3. This plant fires a bituminous coal and has opacity and particulate emissions performance issues related to fly ash re-entrainment. Two cohesivity-specific additive formulations, ADA-44C and ADA-51, will be evaluated. In addition, ammonia conditioning will also be compared.

Theoretical and experimental investigations into the particular features of the process of converting coal gas hydrocarbons on incandescent coke  

SciTech Connect (OSTI)

The prospects of the use of reducing gases in ferrous metallurgy and the possibilities for using them as a basis for coke production have been presented by the authors of the present article in the past. In the present report, the authors present certain results of theoretical and experimental investigations into the process of converting coal gas hydrocarbons on incandescent coke. The modification of the present-day method of thermodynamically calculating stable compositions of coking products, which was developed by the authors, has made it possible to apply it to specific chemical systems and process conditions not met with before, such as the conversion of hydrocarbons in mixtures of actual industrial gases (coal gas and blast furnace gas) in the presence of carbon and considerable amounts of hydrogen.

REDUCING POWER PRODUCTION COSTS BY UTILIZING PETROLEUM COKE  

SciTech Connect (OSTI)

Petroleum coke, a byproduct of the petroleum-refining process, is an attractive primary or supplemental fuel for power production primarily because of a progressive and predictable increase in the production volumes of petroleum coke (1, 2). Petroleum coke is most commonly blended with coal in proportions suitable to meet sulfur emission compliance. Petroleum coke is generally less reactive than coal; therefore, the cofiring of petroleum coke with coal typically improves ignition, flame stability, and carbon loss relative to the combustion of petroleum coke alone. Although petroleum coke is a desirable fuel for producing relatively inexpensive electrical power, concerns about the effects of petroleum coke blending on combustion and pollution control processes exist in the coal-fired utility industry (3). The Energy & Environmental Research Center (EERC) completed a 2-year technical assessment of petroleum coke as a supplemental fuel. A survey questionnaire was sent to seven electric utility companies that are currently cofiring coal and petroleum coke in an effort to solicit specific suggestions on research needs and fuel selections. An example of the letter and survey questionnaire is presented in Appendix A. Interest was expressed by most utilities in evaluating the effects of petroleum coke blending on grindability, combustion reactivity, fouling, slagging, and fly ash emissions control. Unexpectedly, concern over corrosion was not expressed by the utilities contacted. Although all seven utilities responded to the question, only two utilities, Northern States Power Company (NSP) and Ameren, sent fuels to the EERC for evaluation. Both utilities sent subbituminous coals from the Power River Basin and petroleum shot coke samples. Petroleum shot coke is produced unintentionally during operational upsets in the petroleum refining process. This report evaluates the effects of petroleum shot coke blending on grindability, fuel reactivity, fouling/slagging, and electrostatic precipitator (ESP) fly ash collection efficiency.

Coal: An energy bridge to the future  

SciTech Connect (OSTI)

For years, coal drove the transportation business in this country and it may be poised for a comeback when it comes to moving people and things. A hundred years ago, steam engines burned tons of coal as they pulled trains across the country. Now researchers are looking at converting that coal to liquid fuel that would fill up our gas tanks and move our cars and trucks. The technology already exists to transform coal into a liquid fuel. In fact, Pacific Northwest National Laboratory scientists and engineers have researched forms of coal and hydrocarbon gasification on and off for more than 30 years. But oil has never sustained a high enough price to kick start a coal-to-liquid fuel industry. That may be changing now. In addition to high crude oil prices, experts agree worldwide petroleum resources won’t last forever, and hydrocarbon resources like coal may be the only resource available, at a large enough scale, to off-set oil consumption, in the near term.

Modeling high-pressure adsorption of gas mixtures on activated carbon and coal using a simplified local-density model  

SciTech Connect (OSTI)

The simplified local-density (SLD) theory was investigated regarding its ability to provide accurate representations and predictions of high-pressure supercritical adsorption isotherms encountered in coalbed methane (CBM) recovery and CO{sub 2} sequestration. Attention was focused on the ability of the SLD theory to predict mixed-gas adsorption solely on the basis of information from pure gas isotherms using a modified Peng-Robinson (PR) equation of state (EOS). An extensive set of high-pressure adsorption measurements was used in this evaluation. These measurements included pure and binary mixture adsorption measurements for several gas compositions up to 14 MPa for Calgon F-400 activated carbon and three water-moistened coals. Also included were ternary measurements for the activated carbon and one coal. For the adsorption of methane, nitrogen, and CO{sub 2} on dry activated carbon, the SLD-PR can predict the component mixture adsorption within about 2.2 times the experimental uncertainty on average solely on the basis of pure-component adsorption isotherms. For the adsorption of methane, nitrogen, and CO{sub 2} on two of the three wet coals, the SLD-PR model can predict the component adsorption within the experimental uncertainties on average for all feed fractions (nominally molar compositions of 20/80, 40/60, 60/40, and 80/20) of the three binary gas mixture combinations, although predictions for some specific feed fractions are outside of their experimental uncertainties.

Solvent extraction of bituminous coals using light cycle oil: characterization of diaromatic products in liquids  

SciTech Connect (OSTI)

Many studies of the pyrolytic degradation of coal-derived and petroleum-derived aviation fuels have demonstrated that the coal-derived fuels show better thermal stability, both with respect to deposition of carbonaceous solids and cracking to gases. Much previous work at our institute has focused on the use of refined chemical oil (RCO), a distillate from the refining of coal tar, blended with light cycle oil (LCO) from catalytic cracking of vacuum gas oil. Hydroprocessing of this blend forms high concentrations of tetralin and decalin derivatives that confer particularly good thermal stability on the fuel. However, possible supply constraints for RCO make it important to consider alternative ways to produce an 'RCO-like' product from coal in an inexpensive process. This study shows the results of coal extraction using LCO as a solvent. At 350{sup o}C at a solvent-to-coal ratio of 10:1, the conversions were 30-50 wt % and extract yields 28-40 wt % when testing five different coals. When using lower LCO/coal ratios, conversions and extract yields were much smaller; lower LCO/coal ratios also caused mechanical issues. LCO is thought to behave similarly to a nonpolar, non-hydrogen donor solvent, which would facilitate heat-induced structural relaxation of the coal followed by solubilization. The main components contributed from the coal to the extract when using Pittsburgh coal are di- and triaromatic compounds. 41 refs., 3 figs., 12 tabs.

Coal-fueled diesels for modular power generation  

SciTech Connect (OSTI)

Interest in coal-fueled heat engines revived after the sharp increase in the prices of natural gas and petroleum in the 1970`s. Based on the success of micronized coal water slurry combustion tests in an engine in the 1980`s, Morgantown Energy Technology Center (METC) of the US Department of Energy. initiated several programs for the development of advanced coal-fueled diesel and gas turbine engines for use in cogeneration, small utilities, industrial applications and transportation. Cooper-Bessemer and Arthur D. Little have been developing technology since 1985, under the sponsor of METC, to enable coal water slurry (CWS) to be utilized in large bore, medium-speed diesel engines. Modular power generation applications in the 10--100 MW size (each plant typically using from two to eight engines) are the target applications for the late 1990`s and beyond when, according to the US DOE and other projections, oil and natural gas prices are expected to escalate much more rapidly compared to the price of coal. As part of this program over 7.50 hours of prototype engine operation has been achieved on coal water slurry (CWS), including over 100 hours operation of a six-cylinder full scale engine with Integrated Emissions Control System in 1993. In this paper, the authors described the project cost of the CWS fuel used, the heat rate of the engine operating on CWS, the projected maintenance cost for various engine components, and the demonstrated low emissions characteristics of the coal diesel system.

Systems Study for Improving Gas Turbine Performance for Coal/IGCC Application  

SciTech Connect (OSTI)

This study identifies vital gas turbine (GT) parameters and quantifies their influence in meeting the DOE Turbine Program overall Integrated Gasification Combined Cycle (IGCC) plant goals of 50% net HHV efficiency, $1000/kW capital cost, and low emissions. The project analytically evaluates GE advanced F class air cooled technology level gas turbine conceptual cycle designs and determines their influence on IGCC plant level performance including impact of Carbon capture. This report summarizes the work accomplished in each of the following six Tasks. Task 1.0--Overall IGCC Plant Level Requirements Identification: Plant level requirements were identified, and compared with DOE's IGCC Goal of achieving 50% Net HHV Efficiency and $1000/KW by the Year 2008, through use of a Six Sigma Quality Functional Deployment (QFD) Tool. This analysis resulted in 7 GT System Level Parameters as the most significant. Task 2.0--Requirements Prioritization/Flow-Down to GT Subsystem Level: GT requirements were identified, analyzed and prioritized relative to achieving plant level goals, and compared with the flow down of power island goals through use of a Six Sigma QFD Tool. This analysis resulted in 11 GT Cycle Design Parameters being selected as the most significant. Task 3.0--IGCC Conceptual System Analysis: A Baseline IGCC Plant configuration was chosen, and an IGCC simulation analysis model was constructed, validated against published performance data and then optimized by including air extraction heat recovery and GE steam turbine model. Baseline IGCC based on GE 207FA+e gas turbine combined cycle has net HHV efficiency of 40.5% and net output nominally of 526 Megawatts at NOx emission level of 15 ppmvd{at}15% corrected O2. 18 advanced F technology GT cycle design options were developed to provide performance targets with increased output and/or efficiency with low NOx emissions. Task 4.0--Gas Turbine Cycle Options vs. Requirements Evaluation: Influence coefficients on 4 key IGCC plant level parameters (IGCC Net Efficiency, IGCC Net Output, GT Output, NOx Emissions) of 11 GT identified cycle parameters were determined. Results indicate that IGCC net efficiency HHV gains up to 2.8 pts (40.5% to 43.3%) and IGCC net output gains up to 35% are possible due to improvements in GT technology alone with single digit NOx emission levels. Task 5.0--Recommendations for GT Technical Improvements: A trade off analysis was conducted utilizing the performance results of 18 gas turbine (GT) conceptual designs, and three most promising GT candidates are recommended. A roadmap for turbine technology development is proposed for future coal based IGCC power plants. Task 6.0--Determine Carbon Capture Impact on IGCC Plant Level Performance: A gas turbine performance model for high Hydrogen fuel gas turbine was created and integrated to an IGCC system performance model, which also included newly created models for moisturized syngas, gas shift and CO2 removal subsystems. This performance model was analyzed for two gas turbine technology based subsystems each with two Carbon removal design options of 85% and 88% respectively. The results show larger IGCC performance penalty for gas turbine designs with higher firing temperature and higher Carbon removal.

Interaction of iron-copper mixed metal oxide oxygen carriers with simulated synthesis gas derived from steam gasification of coal  

SciTech Connect (OSTI)

The objective of this work was to prepare supported bimetallic Fe–Cu oxygen carriers and to evaluate their performance for the chemical-looping combustion (CLC) process with simulated synthesis gas derived from steam gasification of coal/air. Ten-cycle CLC tests were conducted with Fe–Cu oxygen carriers in an atmospheric thermogravimetric analyzer utilizing simulated synthesis gas derived from the steam gasification of Polish Janina coal and Illinois #6 coal as fuel. The effect of temperature on reaction rates, chemical stability, and oxygen transport capacity were determined. Fractional reduction, fractional oxidation, and global rates of reactions were calculated from the thermogravimetric analysis (TGA) data. The supports greatly affected reaction performance. Data showed that reaction rates and oxygen capacities were stable during the 10-cycle TGA tests for most Fe–Cu/support oxygen carriers. Bimetallic Fe–Cu/support oxygen carriers showed higher reduction rates than Fe-support oxygen carriers. The carriers containing higher Cu content showed better stabilities and better reduction rates. An increase in temperature from 800 °C to 900 °C did not have a significant effect on either the oxygen capacity or the reduction rates with synthesis gas derived from Janina coal. Oxidation reaction was significantly faster than reduction reaction for all supported Fe–Cu oxygen carriers. Carriers with higher Cu content had lower oxidation rates. Ten-cycle TGA data indicated that these oxygen carriers had stable performances at 800–900 °C and might be successfully used up to 900 °C for coal CLC reaction in the presence of steam.

CO2 Sequestration Potential of Texas Low-Rank Coals  

SciTech Connect (OSTI)

The objectives of this project are to evaluate the feasibility of carbon dioxide (CO{sub 2}) sequestration in Texas low-rank coals and to determine the potential for enhanced coalbed methane (CBM) recovery as an added benefit of sequestration. The primary objectives for this reporting period were to construct a coal geological model for reservoir analysis and to continue acquisition of data pertinent to coal characterization that would help in determining the feasibility of carbon dioxide sequestration. Structural analysis and detailed correlation of coal zones are important for reservoir analysis and modeling. Evaluation of existing well logs indicates local structural complexity that complicates interpretations of continuity of the Wilcox Group coal zones. Therefore, we have begun searching for published structural maps for the areas of potential injection CO{sub 2}, near the coal-fired power plants. Preliminary evaluations of data received from Anadarko Petroleum Corporation suggest that coal properties and gas content and chemical composition vary greatly among coal seams. We are assessing the stratigraphic and geographic distributions and the weight of coal samples that Anadarko has provided to select samples for further laboratory analysis. Our goal is to perform additional isotherm analyses with various pure and/or mixed gases to enhance our characterization model. Additionally, we are evaluating opportunities for field determination of permeability with Anadarko, utilizing one of their wells.

Mann (margaret_mann @nrel.gov; (303) 275-2921) National Renewable Energy Laboratory 1617 Cole Boulevard Golden, CO 80401 INTRODUCTION It is technically feasible to capture CO 2 from the flue gas of a coal-fired power plant and various researchers are working to understand the fate of sequestered CO 2 and its long term environmental effects. Sequestering CO 2 significantly reduces the CO 2 emissions from the power plant itself, but this is not the total picture. CO 2 capture and sequestration consumes additional energy, thus lowering the plant's fuel to electricity efficiency. To compensate for this, more fossil fuel must be

JV Task 5 - Evaluation of Residual Oil Fly Ash As A Mercury Sorbent For Coal Combustion Flue Gas  

SciTech Connect (OSTI)

The mercury adsorption capacity of a residual oil fly ash (ROFA) sample collected form Florida Power and Light Company's Port Everglades Power Plant was evaluated using a bituminous coal combustion flue gas simulator and fixed-bed testing protocol. A size-segregated (>38 {micro}g) fraction of ROFA was ground to a fine powder and brominated to potentially enhance mercury capture. The ROFA and brominated-ROFA were ineffective in capturing or oxidizing the Hg{sup 0} present in a simulated bituminous coal combustion flue gas. In contrast, a commercially available DARCO{reg_sign} FGD initially adsorbed Hg{sup 0} for about an hour and then catalyzed Hg{sup 0} oxidation to produce Hg{sup 2+}. Apparently, the unburned carbon in ROFA needs to be more rigorously activated in order for it to effectively capture and/or oxidize Hg{sup 0}.

Tracking Progress Current and Expected Energy from Coal for California  

E-Print Network [OSTI]

Electricity supplies from existing coal and petroleum coke plants represent about 10 percent of the total energy requirements to serve loads in California load during 2010, and they account for about 29 percent of all greenhouse gas emissions attributed to the electricity sector. Available capacity and energy supplies from these power plants are tied to long-term contracts, some of which have been in place for several decades. Table 1 provides a listing of dependable capacity to California utilities in 2011 from out-of-state coal plants.

Organic substances in produced and formation water from unconventional natural gas extraction in coal and shale  

Science Journals Connector (OSTI)

Abstract Organic substances in produced and formation water from coalbed methane (CBM) and gas shale plays from across the USA were examined in this study. Disposal of produced waters from gas extraction in coal and shale is an important environmental issue because of the large volumes of water involved and the variable quality of this water. Organic substances in produced water may be environmentally relevant as pollutants, but have been little studied. Results from five CBM plays and two gas shale plays (including the Marcellus Shale) show a myriad of organic chemicals present in the produced and formation water. Organic compound classes present in produced and formation water in CBM plays include: polycyclic aromatic hydrocarbons (PAHs), heterocyclic compounds, alkyl phenols, aromatic amines, alkyl aromatics (alkyl benzenes, alkyl biphenyls), long-chain fatty acids, and aliphatic hydrocarbons. Concentrations of individual compounds range from CBM samples) range from 50 to 100 ?g/L. Total dissolved organic carbon (TOC) in CBM produced water is generally in the 1–4 mg/L range. Excursions from this general pattern in produced waters from individual wells arise from contaminants introduced by production activities (oils, grease, adhesives, etc.). Organic substances in produced and formation water from gas shale unimpacted by production chemicals have a similar range of compound classes as CBM produced water, and TOC levels of about 8 mg/L. However, produced water from the Marcellus Shale using hydraulic fracturing has TOC levels as high as 5500 mg/L and a range of added organic chemicals including, solvents, biocides, scale inhibitors, and other organic chemicals at levels of 1000 s of ?g/L for individual compounds. Levels of these hydraulic fracturing chemicals and TOC decrease rapidly over the first 20 days of water recovery and some level of residual organic contaminants remain up to 250 days after hydraulic fracturing. Although the environmental impacts of the organics in produced water are not well defined, results suggest that care should be exercised in the disposal and release of produced waters containing these organic substances into the environment because of the potential toxicity of many of these substances.

Blast furnace coke quality in relation to petroleum coke addition  

SciTech Connect (OSTI)

The incorporation of petroleum coke as an additive in industrial coking coal blends is a practice often used by steel companies. A suitable blast furnace coke produced by replacing part of the coking coal blend with a suitable petroleum coke (addition of 5 to 15%), was made by Great Lakes Carbon Corporation and successfully tested at several blast furnaces. This coke had lower reactivity, less ash and slightly higher sulfur content than coke made without the addition of petroleum coke. In contrast with these results, it has been reported in a BCRA study that additions of petroleum coke to a strong coking coal, above 5 wt%, increased coke reactivity. These differences may be explained on the basis of the coal or blend characteristics to which petroleum coke is added. Petroleum coke addition seems to give better results if the coal/blend has high fluidity. The present situation in Spain is favorable for the use of petroleum coke. So, a study of laboratory and semi-industrial scale was made to assess the possibility of using petroleum coke as an additive to the typical industrial coal blend coked by the Spanish Steel Company, ENSIDESA. The influence of the petroleum coke particle size was also studied to semi-industrial scale.

Preliminary research of health and environmental impacts and greenhouse gas emission from coal-fired power and nuclear power chains in China  

Science Journals Connector (OSTI)

The present paper treats health, environmental impacts and greenhouse gas emission resulting from both the coal-fired power chain and nuclear power chain in China. The nuclear power chain resulted in adverse health impacts 3-4 orders of magnitude lower than those from the coal-fired power chain, also radiological emissions were 1-2 orders of magnitude lower. Estimated greenhouse gas emission factors amount to 40 fold. The coal-fired power chain is considered to be one of the major sources of environmental pollution in China and rapid expansion of nuclear power in the country promises to be one of the primary ways of mitigating environmental pollution and reducing greenhouse gas emission. At the same time, of course, it is also necessary to increase the energy conversion efficiency of coal as a fuel and to minimise pollutant discharge.

ADVANCED FLUE GAS CONDITIONING AS A RETROFIT UPGRADE TO ENHANCE PM COLLECTION FROM COAL-FIRED ELECTRIC UTILITY BOILERS  

SciTech Connect (OSTI)

The U.S. Department of Energy and ADA Environmental Solutions are engaged in a project to develop commercial flue gas conditioning additives. The objective is to develop conditioning agents that can help improve particulate control performance of smaller or under-sized electrostatic precipitators on utility coal-fired boilers. The new chemicals will be used to control both the electrical resistivity and the adhesion or cohesivity of the fly ash. There is a need to provide cost-effective and safer alternatives to traditional flue gas conditioning with SO{sub 3} and ammonia. During this reporting quarter, performance testing of flue gas conditioning was underway at the PacifiCorp Jim Bridger Power Plant. The product tested, ADA-43, was a combination resistivity modifier with cohesivity polymers. This represents the first long-term full-scale testing of this class of products. Modifications to the flue gas conditioning system at Jim Bridger, including development of alternate injection lances, was also undertaken to improve chemical spray distribution and to avoid spray deposition to duct interior surfaces. Also in this quarter, a firm commitment was received for another long-term test of the cohesivity additives. This plant fires a bituminous coal and has opacity and particulate emissions performance issues related to fly ash re-entrainment. Ammonia conditioning is employed here on one unit, but there is interest in liquid cohesivity additives as a safer alternative.

Chapter 3 - Hydrocarbons from Petroleum  

Science Journals Connector (OSTI)

Publisher Summary Petroleum products (in contrast to petrochemicals) are those hydrocarbon fractions that are derived from petroleum and have commercial value as a bulk product. A major group of hydrocarbon products from petroleum (petrochemicals) are the basis of a major industry. They are, in the strictest sense, different to petroleum products insofar as the petrochemicals are the basic building blocks of the chemical industry. The specific gravity of product gases, including liquefied petroleum gas, may be determined conveniently by a number of methods and a variety of instruments. The heat value of gases is generally determined at constant pressure in a flow calorimeter in which the heat released by the combustion of a definite quantity of gas is absorbed by a measured quantity of water or air. A continuous recording calorimeter is available for measuring heat values of natural gases.

CO2 Sequestration Potential of Texas Low-Rank Coals  

SciTech Connect (OSTI)

The objective of this project is to evaluate the feasibility of carbon dioxide (CO{sub 2}) sequestration in Texas low-rank coals and to determine the potential for enhanced coalbed methane (CBM) recovery as an added benefit of sequestration. The main objectives for this reporting period were to further characterize the three areas selected as potential test sites, to begin assessing regional attributes of natural coal fractures (cleats), which control coalbed permeability, and to interview laboratories for coal sample testing. An additional objective was to initiate discussions with an operating company that has interests in Texas coalbed gas production and CO{sub 2} sequestration potential, to determine their interest in participation and cost sharing in this project. Well-log data are critical for defining depth, thickness, number, and grouping of coal seams at the proposed sequestration sites. Therefore, we purchased 15 well logs from a commercial source to make coal-occurrence maps and cross sections. Log suites included gamma ray (GR), self potential (SP), resistivity, sonic, and density curves. Other properties of the coals in the selected areas were collected from published literature. To assess cleat properties and describe coal characteristics, we made field trips to a Jackson coal outcrop and visited Wilcox coal exposures at the Sandow surface mine. Coal samples at the Sandow mine were collected for CO{sub 2} and methane sorption analyses. We contacted several laboratories that specialize in analyzing coals and selected a laboratory, submitting the Sandow Wilcox coals for analysis. To address the issue of cost sharing, we had fruitful initial discussions with a petroleum corporation in Houston. We reviewed the objectives and status of this project, discussed data that they have already collected, and explored the potential for cooperative data acquisition and exchange in the future. We are pursuing a cooperative agreement with them.

Pilot Scale Water Gas Shift - Membrane Device for Hydrogen from Coal  

SciTech Connect (OSTI)

The objectives of the project were to build pilot scale hydrogen separation systems for use in a gasification product stream. This device would demonstrate fabrication and manufacturing techniques for producing commercially ready facilities. The design was a 2 lb/day hydrogen device which included composite hydrogen separation membranes, a water gas shift monolith catalyst, and stainless steel structural components. Synkera Technologies was to prepare hydrogen separation membranes with metallic rims, and to adjust the alloy composition in their membranes to a palladium-gold composition which is sulfur resistant. Chart was to confirm their brazing technology for bonding the metallic rims of the composite membranes to their structural components and design and build the 2 lbs/day device incorporating membranes and catalysts. WRI prepared the catalysts and completed the testing of the membranes and devices on coal derived syngas. The reactor incorporated eighteen 2'' by 7'' composite palladium alloy membranes. These membranes were assembled with three stacks of three paired membranes. Initial vacuum testing and visual inspection indicated that some membranes were cracked, either in transportation or in testing. During replacement of the failed membranes, while pulling a vacuum on the back side of the membranes, folds were formed in the flexible composite membranes. In some instances these folds led to cracks, primarily at the interface between the alumina and the aluminum rim. The design of the 2 lb/day device was compromised by the lack of any membrane isolation. A leak in any membrane failed the entire device. A large number of tests were undertaken to bring the full 2 lb per day hydrogen capacity on line, but no single test lasted more than 48 hours. Subsequent tests to replace the mechanical seals with brazing have been promising, but the technology remains promising but not proven.

JV Task 124 - Understanding Multi-Interactions of SO3, Mercury, Selenium, and Arsenic in Illinois Coal Flue Gas  

SciTech Connect (OSTI)

This project consisted of pilot-scale combustion testing with a representative Illinois basin coal to explore the multi-interactions of SO{sub 3}, mercury, selenium and arsenic. The parameters investigated for SO{sub 3} and mercury interactions included different flue gas conditions, i.e., temperature, moisture content, and particulate alkali content, both with and without activated carbon injection for mercury control. Measurements were also made to track the transformation of selenium and arsenic partitioning as a function of flue gas temperature through the system. The results from the mercury-SO{sub 3} testing support the concept that SO{sub 3} vapor is the predominant factor that impedes efficient mercury removal with activated carbon in an Illinois coal flue gas, while H{sub 2}SO{sub 4} aerosol has less impact on activated carbon injection performance. Injection of a suitably mobile and reactive additives such as sodium- or calcium-based sorbents was the most effective strategy tested to mitigate the effect of SO{sub 3}. Transformation measurements indicate a significant fraction of selenium was associated with the vapor phase at the electrostatic precipitator inlet temperature. Arsenic was primarily particulate-bound and should be captured effectively with existing particulate control technology.

ADVANCED FLUE GAS CONDITIONING AS A RETROFIT UPGRADE TO ENHANCE PM COLLECTION FROM COAL-FIRED ELECTRIC UTILITY BOILERS  

SciTech Connect (OSTI)

The U.S. Department of Energy and ADA Environmental Solutions are engaged in a project to develop commercial flue gas conditioning additives. The objective is to develop conditioning agents that can help improve particulate control performance of smaller or under-sized electrostatic precipitators on utility coal-fired boilers. The new chemicals will be used to control both the electrical resistivity and the adhesion or cohesivity of the fly ash. There is a need to provide cost-effective and safer alternatives to traditional flue gas conditioning with SO{sub 3} and ammonia. During this reporting quarter, installation of a flue gas conditioning system was completed at PacifiCorp Jim Bridger Power Plant. Performance testing was underway. Results will be detailed in the next quarterly and subsequent technical summary reports. Also in this quarter, discussions were initiated with a prospective long-term candidate plant. This plant fires a bituminous coal and has opacity performance issues related to fly ash re-entrainment. Ammonia conditioning has been proposed here, but there is interest in liquid additives as a safer alternative.

Underground coal gasification (UCG) gas to methanol and MTG-gasoline: an economic and sensitivity study, Task B  

SciTech Connect (OSTI)

This report, identified as Task B, examines the technical and economic aspects of the production of methanol and MTG-Gasoline using gas from an underground coal gasification (UCG) facility. The report is a sequel to a previous study performed in 1981 and identified as Task A. The Task A report, titled Cost Saving Concepts on the Production of Methanol from Underground Gasified Coal, examined the economics of producing fuel grade methanol using UCG gas. In this study we examine the economics of producing MTG-Gasoline as well as a number of other aspects of the economics of upgrading UCG gas. Capital and operating costs for three different capacities of MTG-Gasoline plant are presented. These are 1600 BPD, 4800 BPD, and 9600 BPD. These capacities are equivalent to fuel grade methanol plants having capacities of 4000 BPD, 12,000 BPD, and 24,000 BPD - the methanol capacities considered in the previous studies. The economics of the MTG-Gasoline plant were developed using published information and our best estimate of the processing steps in the MTG-Gasoline process. As part of this study, several sensitivity studies were undertaken to examine the sensitivity of both methanol and MTG-Gasoline product cost to changes in technical and economic parameters. Table 1.1 lists the various sensitivity studies undertaken. All cost figures are in first quarter 1982 dollars.

The new chemicals will be used to control both the electrical resistivity and the adhesion or cohesivity of the fly ash. There is a need to provide cost-effective and safer alternatives to traditional flue gas conditioning with SO{sub 3} and ammonia. During this reporting quarter, performance testing of flue gas conditioning was completed at the PacifiCorp Jim Bridger Power Plant. The product tested, ADA-43, was a combination resistivity modifier with cohesivity polymers. The product was effective as a flue gas conditioner. However, ongoing problems with in-duct deposition resulting from the flue gas conditioning were not entirely resolved. Primarily these problems were the result of difficulties encountered with retrofit of an existing spray humidification system. Eventually it proved necessary to replace all of the original injection lances and to manually bypass the PLC-based air/liquid feed control. This yielded substantial improvement in spray atomization and system reliability. However, the plant opted not to install a permanent system. Also in this quarter, preparations continued for a test of the cohesivity additives at the American Electric Power Conesville Plant, Unit 3. This plant fires a bituminous coal and has opacity and particulate emissions performance issues related to fly ash re-entrainment. Ammonia conditioning is employed here on one unit, but there is interest in liquid cohesivity additives as a safer alternative.

REDUCING POWER PRODUCTION COSTS BY UTILIZING PETROLEUM COKE  

SciTech Connect (OSTI)

A Powder River Basin subbituminous coal from the North Antelope mine and a petroleum shot coke were received from Northern States Power Company (NSP) for testing the effects of parent fuel properties on coal-coke blend grindability and evaluating the utility of petroleum coke blending as a strategy for improving electrostatic precipitator (ESP) particulate collection efficiency. Petroleum cokes are generally harder than coals, as indicated by Hardgrove grindability tests. Therefore, the weaker coal component may concentrate in the finer size fractions during the pulverizing of coal-coke blends. The possibility of a coal-coke size fractionation effect is being investigated because it may adversely affect combustion performance. Although the blending of petroleum coke with coal may adversely affect combustion performance, it may enhance ESP particulate collection efficiency. Petroleum cokes contain much higher concentrations of V relative to coals. Consequently, coke blending can significantly increase the V content of fly ash resulting from coal-coke combustion. Pentavalent vanadium oxide (V{sub 2}O{sub 5}) is a known catalyst for transforming gaseous sulfur dioxide (SO{sub 2}[g]) to gaseous sulfur trioxide (SO{sub 3}[g]). The presence of SO{sub 3}(g) strongly affects fly ash resistivity and, thus, ESP performance.

Investigations into coal coprocessing and coal liquefaction  

SciTech Connect (OSTI)

The conversion of coal to liquid suitable as feedstock to a petroleum refinery is dependent upon several process variables. These variables include temperature, pressure, coal rank, catalyst type, nature of the feed to the reactor, type of process, etc. Western Research Institute (WRI) has initiated a research program in the area of coal liquefaction to address the impact of some of these variables upon the yield and quality of the coal-derived liquid. The principal goal of this research is to improve the efficiency of the coal liquefaction process. Two different approaches are currently being investigated. These include the coprocessing of a heavy liquid, such as crude oil, and coal using a dispersed catalyst and the direct liquefaction of coal using a supported catalyst. Another important consideration in coal liquefaction is the utilization of hydrogen, including both externally- and internally-supplied hydrogen. Because the incorporation of externally-supplied hydrogen during conversion of this very aromatic fossil fuel to, for example, transportation fuels is very expensive, improved utilization of internally-supplied hydrogen can lead to reducing processing costs. The objectives of this investigation, which is Task 3.3.4, Coal Coprocessing, of the 1991--1992 Annual Research Plan, are: (1) to evaluate coal/oil pretreatment conditions that are expected to improve the liquid yield through more efficient dispersion of an oil-soluble, iron-based catalyst, (2) to characterize the coke deposits on novel, supported catalysts after coal liquefaction experiments and to correlate the carbon skeletal structure parameters of the coke deposit with catalyst performance as measured by coal liquefaction product yield, and (3) to determine the modes of hydrogen utilization during coal liquefaction and coprocessing. Experimental results are discussed in this report.

Electrochemical, Structural and Surface Characterization of Nickel/Zirconia Solid Oxide Fuel Cell Anodes in Coal Gas Containing Antimony  

SciTech Connect (OSTI)

The interaction of antimony with the nickel-zirconia solid oxide fuel cell (SOFC) anode has been investigated. Tests with both anode-supported and electrolyte-supported button cells were performed at 700 and 800oC in synthetic coal gas containing 10 ppb to 9 ppm antimony. Minor performance loss was observed immediately after Sb introduction to coal gas resulting in ca. 5 % power output drop. While no further degradation was observed during the following several hundred hours of testing, cells abruptly and irreversibly failed after 800-1500 hours depending on Sb concentration and test temperature. Antimony was found to interact strongly with nickel and result in extensive alteration phase formation, consistent with expectations based on thermodynamic properties. Nickel antimonide phases, NiSb and Ni5Sb2, were partially coalesced into large grains and eventually affected electronic percolation through the anode support. Initial degradation was attributed to diffusion of antimony to the active anode/electrolyte interface to form an adsorption layer.

Enhancing the use of coals by gas reburning-sorbent injection. Quarterly report No. 20, July 1--September 30, 1992  

SciTech Connect (OSTI)

The objective of this project is to evaluate and demonstrate a cost effective emission control technology for acid rain precursors, oxides of nitrogen (NO{sub x}) and sulfur (SO{sub x}) on two coal fired utility boilers in Illinois. The units selected are representative of pre-NSPS design practices: tangential and cyclone fired. Work on a third unit, wall fired, has been stopped because of funding limitations. The specific objectives are to demonstrate reductions of 60 percent in NO{sub x} and 50 percent in SO{sub x} emissions, by a combination of two developed technologies, gas reburning (GR) and sorbent injection (SI). With GR, about 80--85 percent of the coal fuel is fired in the primary combustion zone. The balance of the fuel is added downstream as natural gas to create a slightly fuel rich environment in which NO{sub x} is converted to N{sub 2}. The combustion process is completed by overfire air addition. So{sub x} emissions are reduced by injecting dry sorbents (usually calcium based) into the upper furnace. The sorbents trap SO{sub x} as solid sulfates that are collected in the particulate control device. This project is conducted in three phases at each site: (1) Design and Permitting; (2) Construction and Startup; and, (3) Operation, Data Collection, Reporting and Disposition. Technology transfer to industry is accomplished through the formation of an industry panel.

User-Friendly Tool to Calculate Economic Impacts from Coal, Natural Gas, and Wind: The Expanded Jobs and Economic Development Impact Model (JEDI II); Preprint  

SciTech Connect (OSTI)

In this paper we examine the impacts of building new coal, gas, or wind plants in three states: Colorado, Michigan, and Virginia. Our findings indicate that local/state economic impacts are directly related to the availability and utilization of local industries and services to build and operate the power plant. For gas and coal plants, the economic benefit depends significantly on whether the fuel is obtained from within the state, out of state, or some combination. We also find that the taxes generated by power plants can have a significant impact on local economies via increased expenditures on public goods.

Development of a Hydrogasification Process for Co-Production of Substitute Natural Gas (SNG) and Electric Power from Western Coals  

SciTech Connect (OSTI)

This report presents the results of the research and development conducted on an Advanced Hydrogasification Process (AHP) conceived and developed by Arizona Public Service Company (APS) under U.S. Department of Energy (DOE) contract: DE-FC26-06NT42759 for Substitute Natural Gas (SNG) production from western coal. A double-wall (i.e., a hydrogasification contained within a pressure shell) down-flow hydrogasification reactor was designed, engineered, constructed, commissioned and operated by APS, Phoenix, AZ. The reactor is ASME-certified under Section VIII with a rating of 1150 pounds per square inch gage (psig) maximum allowable working pressure at 1950 degrees Fahrenheit ({degrees}F). The reaction zone had a 1.75 inch inner diameter and 13 feet length. The initial testing of a sub-bituminous coal demonstrated ~ 50% carbon conversion and ~10% methane yield in the product gas under 1625{degrees}F, 1000 psig pressure, with a 11 seconds (s) residence time, and 0.4 hydrogen-to-coal mass ratio. Liquid by-products mainly contained Benzene, Toluene, Xylene (BTX) and tar. Char collected from the bottom of the reactor had 9000-British thermal units per pound (Btu/lb) heating value. A three-dimensional (3D) computational fluid dynamic model simulation of the hydrodynamics around the reactor head was utilized to design the nozzles for injecting the hydrogen into the gasifier to optimize gas-solid mixing to achieve improved carbon conversion. The report also presents the evaluation of using algae for carbon dioxide (CO{sub 2}) management and biofuel production. Nannochloropsis, Selenastrum and Scenedesmus were determined to be the best algae strains for the project purpose and were studied in an outdoor system which included a 6-meter (6M) radius cultivator with a total surface area of 113 square meters (m{sup 2}) and a total culture volume between 10,000 to 15,000 liters (L); a CO{sub 2} on-demand feeding system; an on-line data collection system for temperature, pH, Photosynthetically Activate Radiation (PAR) and dissolved oxygen (DO); and a ~2 gallons per minute (gpm) algae culture dewatering system. Among the three algae strains, Scenedesmus showed the most tolerance to temperature and irradiance conditions in Phoenix and the best self-settling characteristics. Experimental findings and operational strategies determined through these tests guided the operation of the algae cultivation system for the scale-up study. Effect of power plant flue gas, especially heavy metals, on algae growth and biomass adsorption were evaluated as well.

Development of a high-performance coal-fired power generating system with pyrolysis gas and char-fired high temperature furnace (HITAF)  

SciTech Connect (OSTI)

A concept for an advanced coal-fired combined-cycle power generating system is currently being developed. The first phase of this three-phase program consists of conducting the necessary research and development to define the system, evaluating the economic and technical feasibility of the concept, and preparing an R D plan to develop the concept further. The power generating system being developed in this project will be an improvement over current coal-fired systems. Goals have been specified that relate to the efficiency, emissions, costs, and general operation of the system. The system proposed to meet these goals is a combined-cycle system where air for a gas turbine is indirectly heated to approximately 1800[degrees]F in furnaces fired with coal-derived fuels and then directly heated in a natural-gas-fired combustor to about 2400[degrees]F. The system is based on a pyrolyzing process that converts the coal into a low-Btu fuel gas and char. The fuel gas is relatively clean, and it is fired to heat tube surfaces that are susceptible to corrosion and problems from ash deposition. In particular, the high-temperature air heater tubes, which will need to be a ceramic material, will be located in a separate furnace or region of a furnace that is exposed to combustion products from the low-Btu fuel gas only.

High-pressure coal fuel processor development  

SciTech Connect (OSTI)

Caterpillar shares DOE/METC interest in demonstrating the technology required to displace petroleum-based engine fuels with various forms of low cost coal. Current DOE/METC programs on mild gasification and coal-water-slurries are addressing two approaches to this end. Engine and fuel processor system concept studies by Caterpillar have identified a third, potentially promising, option. This option includes high-pressure fuel processing of run-of-the-mine coal and direct injection of the resulting low-Btu gas stream into an ignition assisted, high compression ratio diesel engine. The compactness and predicted efficiency of the system make it suitable for application to line-haul railroad locomotives. Two overall conclusions resulted from Task 1. First direct injected, ignition assisted Diesel cycle engine combustion systems can be suitably modified to efficiently utilize low-Btu gas fuels. Second, high pressure gasification of selected run-of-the-mine coals in batch-loaded fuel processors is feasible. These two findings, taken together, significantly reduce the perceived technical risk associated with the further development of the proposed coal gas fueled Diesel cycle power plant concept. The significant conclusions from Task 2 were: An engine concept, derived from a Caterpillar 3600 series engine, and a fuel processor concept, based on scaling up a removable-canister configuration from the test rig, appear feasible; and although the results of this concept study are encouraging, further, full-scale component research and development are required before attempting a full-scale integrated system demonstration effort.

Measurement of gas species, temperatures, coal burnout, and wall heat fluxes in a 200 MWe lignite-fired boiler with different overfire air damper openings  

SciTech Connect (OSTI)

Measurements were performed on a 200 MWe, wall-fired, lignite utility boiler. For different overfire air (OFA) damper openings, the gas temperature, gas species concentration, coal burnout, release rates of components (C, H, and N), furnace temperature, and heat flux and boiler efficiency were measured. Cold air experiments for a single burner were conducted in the laboratory. The double-swirl flow pulverized-coal burner has two ring recirculation zones starting in the secondary air region in the burner. As the secondary air flow increases, the axial velocity of air flow increases, the maxima of radial velocity, tangential velocity and turbulence intensity all increase, and the swirl intensity of air flow and the size of recirculation zones increase slightly. In the central region of the burner, as the OFA damper opening widens, the gas temperature and CO concentration increase, while the O{sub 2} concentration, NOx concentration, coal burnout, and release rates of components (C, H, and N) decrease, and coal particles ignite earlier. In the secondary air region of the burner, the O{sub 2} concentration, NOx concentration, coal burnout, and release rates of components (C, H, and N) decrease, and the gas temperature and CO concentration vary slightly. In the sidewall region, the gas temperature, O{sub 2} concentration, and NOx concentration decrease, while the CO concentration increases and the gas temperature varies slightly. The furnace temperature and heat flux in the main burning region decrease appreciably, but increase slightly in the burnout region. The NOx emission decreases from 1203.6 mg/m{sup 3} (6% O{sub 2}) for a damper opening of 0% to 511.7 mg/m{sup 3} (6% O{sub 2}) for a damper opening of 80% and the boiler efficiency decreases from 92.59 to 91.9%. 15 refs., 17 figs., 3 tabs.

Economic comparison between coal-fired and liquefied natural gas combined cycle power plants considering carbon tax: Korean case  

Science Journals Connector (OSTI)

Economic growth is main cause of environmental pollution and has been identified as a big threat to sustainable development. Considering the enormous role of electricity in the national economy, it is essential to study the effect of environmental regulations on the electricity sector. This paper aims at making an economic analysis of Korea's power plant utilities by comparing electricity generation costs from coal-fired power plants and liquefied natural gas (LNG) combined cycle power plants with environmental consideration. In this study, the levelized generation cost method (LGCM) is used for comparing economic analysis of power plant utilities. Among the many pollutants discharged during electricity generation, this study principally deals with control costs related only to CO2 and NO2, since the control costs of SO2 and total suspended particulates (TSP) are already included in the construction cost of utilities. The cost of generating electricity in a coal-fired power plant is compared with such cost in a LNG combined cycle power plant. Moreover, a sensitivity analysis with computer simulation is performed according to fuel price, interest rates and carbon tax. In each case, these results can help in deciding which utility is economically justified in the circumstances of environmental regulations.

ADVANCED FLUE GAS CONDITIONING AS A RETROFIT UPGRADE TO ENHANCE PM COLLECTION FROM COAL-FIRED ELECTRIC UTILITY BOILERS  

SciTech Connect (OSTI)

The U.S. Department of Energy and ADA Environmental Solutions are engaged in a project to develop commercial flue gas conditioning additives. The objective is to develop conditioning agents that can help improve particulate control performance of smaller or under-sized electrostatic precipitators on utility coal-fired boilers. The new chemicals will be used to control both the electrical resistivity and the adhesion or cohesivity of the fly ash. There is a need to provide cost-effective and safer alternatives to traditional flue gas conditioning with SO{sub 3} and ammonia. This quarterly report summarizes project activity for the period April-June, 2003. In this period there was limited activity and no active field trials. Results of ash analysis from the AEP Conesville demonstration were received. In addition, a site visit was made to We Energies Presque Isle Power Plant and a proposal extended for a flue gas conditioning trial with the ADA-51 cohesivity additive. It is expected that this will be the final full-scale evaluation on the project.

Enhancing the use of coals by gas reburning-sorbent injection. Quarterly report, January 1--March 31, 1996  

SciTech Connect (OSTI)

The objective of this project is to evaluate and demonstrate a cost effective emission control technology for acid rain precursors, oxides of nitrogen (NO{sub x}) and sulfur (SO{sub x}), on two coal fired utility boilers in Illinois. The units selected are representative of pre-NSPS design practices: tangential and cyclone fired. Work on a third unit, wall fired, has been stopped because of funding limitations. The specific objectives are to demonstrate reductions of 60 percent in NO{sub x} and 50 percent in SO{sub x} emissions, by a combination of two developed technologies, gas reburning (GR) and sorbent injection (SI). With GR, about 80--85 percent of the coal fuel is fired in the primary combustion zone. The balance of the fuel is added downstream as natural gas to create a slightly fuel rich environment in which NO{sub x} is converted to N{sub 2}. The combustion process is completed by overfire air addition. SO{sub x} emissions are reduced by injecting dry sorbents (usually calcium based) into the upper furnace. The sorbents trap SO{sub x} as solid sulfates that are collected in the particulate control device. This project is conducted in three phases at each site: (1) Design and Permitting, (2) Construction and Startup, and (3) Operation, Data Collection, Reporting and Disposition. Technology transfer to industry is accomplished through the formation of an industry panel. Phase I of the project commenced on June 5, 1987. Phases I, II and III for the Illinois Power Project have been completed; Phases I and II for the CWLP project have been completed; Phase III is in progress. All site activities have been completed with the exception of restoration at CWLP.

Current status of MHI CO2 capture plant technology, large scale demonstration project and road map to commercialization for coal fired flue gas application  

Science Journals Connector (OSTI)

(1) It is becoming increasingly evident that the prolonged utilization of fossil fuels for primary energy production, especially coal which is relatively cheap and abundant, is inevitable and that Carbon Capture and Storage (CCS) technology can significantly reduce CO2 emissions from this sector thus allowing the continued environmentally sustainable use of this important energy commodity on a global basis. (2) MHI has co-developed the Kansai Mitsubishi Carbon Dioxide Recovery Process (KM-CDR Process™) and KS-1™ absorbent, which has been deployed in seven CO2 capture plants, now under commercial operation operating at a CO2 capture capacity of 450 metric tons per day (tpd). In addition, a further two commercial plants are now under construction all of which capture CO2 from natural gas fired flue gas boilers and steam reformers. Accordingly this technology is now available for commercial scale CO2 capture for gas boiler and gas turbine application. (3) However before offering commercial CO2 capture plants for coal fired flue gas application, it is necessary to verify the influence of, and develop countermeasures for, related impurities contained in coal fired flue gas. This includes the influence on both the absorbent and the entire system of the CO2 capture plant to achieve high operational reliability and minimize maintenance requirements. (4) Preventing the accumulation of impurities, especially the build up of dust, is very important when treating coal fired flue gas and MHI has undertaken significant work to understand the impact of impurities in order to achieve reliable and stable operating conditions and to efficiently optimize integration between the CO2 capture plant, the coal fired power plant and the flue gas clean up equipment. (5) To achieve this purpose, MHI constructed a 10 tpd CO2 capture demonstration plant at the Matsushima 1000 MW Power Station and confirmed successful, long term demonstration following ?5000 hours of operation in 2006–07 with 50% financial support by RITE, as a joint program to promote technological development with the private sector, and cooperation from J-POWER. (6) Following successful demonstration testing at Matsushima, additional testing was undertaken in 2008 to examine the impact of entrainment of higher levels of flue gas impurities (primarily \\{SOx\\} and dust by bypassing the existing FGD) and to determine which components of the CO2 recovery process are responsible for the removal of these impurities. Following an additional 1000 demonstration hours, results indicated stable operational performance in relation to the following impurities; (1) SO2: Even at higher SO2 concentrations were almost completely removed from the flue gas before entering the CO2 absorber. (2) Dust: The accumulation of dust in the absorbent was higher, leading to an advanced understanding of the behavior of dust in the CO2 capture plant and the dust removal efficiency of each component within the CO2 recovery system. The data obtained is useful for the design of large-scale units and confirms the operating robustness of the CO2 capture plant accounting for wide fluctuations in impurity concentrations. (7) This important coal fired flue gas testing showed categorically that minimizing the accumulation of large concentrations of impurities, and to suppress dust concentrations below a prescribed level, is important to achieve long-term stable operation and to minimize maintenance work for the CO2 capture plant. To comply with the above requirement, various countermeasures have been developed which include the optimization of the impurity removal technology, flue gas pre treatment and improved optimization with the flue gas desulfurization facility. (8) In case of a commercial scale CO2 capture plant applied for coal fired flue gas, its respective size will be several thousand tpd which represents a considerable scale-up from the 10 tpd demonstration plant. In order to ensure the operational reliability and to accurately confirm the influence and the behavior of the impurities in coal fired fl

The economical production of alcohol fuels from coal-derived synthesis gas. Sixth quarterly technical progress report, January 1, 1993--March 31, 1993  

SciTech Connect (OSTI)

Preliminary economic investigations have focused on cost reduction measures in the production of syngas from coal. A spread sheet model has been developed which can determine the cost of syngas production based upon the cost of equipment and raw materials and the market value of energy and by-products. In comparison to natural gas derived syngas, coal derived syngas is much more expensive, suggesting a questionable economic status of coal derived alcohol fuels. While it is possible that use of less expensive coal or significant integration of alcohol production and electricity production may reduce the cost of coal derived syngas, it is unlikely to be less costly to produce than syngas from natural gas. Fuels evaluation is being conducted in three parts. First, standard ASTM tests are being used to analyze the blend characteristics of higher alcohols. Second, the performance characteristics of higher alcohols are being evaluated in a single-cylinder research engine. Third, the emissions characteristics of higher alcohols are being investigated. The equipment is still under construction and the measurement techniques are still being developed. Of particular interest is n-butanol, since the MoS{sub 2} catalyst produces only linear higher alcohols. There is almost no information on the combustion and emission characteristics of n-butanol, hence the importance of gathering this information in this research.

Cogeneration of substitute natural gas and power from coal by moderate recycle of the chemical unconverted gas  

Science Journals Connector (OSTI)

Abstract The thermodynamic analysis and the coupling and optimization between chemical synthesis and power generation in a polygeneration system are presented. Unlike full conversion of syngas into chemicals in the traditional SNG (synthetic natural gas) production system, by moderate conversion the sharp increase in energy consumption for SNG synthesis can be avoided in the new system. Also, by recovering the chemical unconverted gas for combined cycle, electricity is cogenerated efficiently. Results show that the overall efficiency of the novel system can be as high as 59%–65%. And compared to single production systems, the (energy saving ratio) ESR of the new system is over 11.0% and the energy consumption for SNG production can be decreased by around 12%. Sensitivity analysis shows that an optimized conversion ratio of SNG, (chemicals to power output ratio) CPOR, recycle ratio of the unconverted gas Ru, and pressure ratio of gas turbine can lead to the maximum of ESR. Abolishing the syngas composition adjustment and improving the inlet temperature of gas turbine both can help to enhance the system efficiency. Under low Ru, improving the H2/CO mole ratio in the syngas helps to improve system efficiency, while under high Ru, an optimized H2/CO can lead to the maximum of ESR.

SciTech Connect (OSTI)

Laboratory and bench scale reactor research carried out during the report period confirms the feasibility of biomethanation of Texas lignite (TxL) and some other low-rank coals to methane by specifically developed unique anaerobic microbial consortia. The data obtained demonstrates specificity of a particular microbial consortium to a given lignite. Development of a suitable microbial consortium is the key to the success of the process. The Mic-1 consortium was developed to tolerate higher coal loadings of 1 and 5% TxL in comparison to initial loadings of 0.01% and 0.1% TxL. Moreover, the reaction period was reduced from 60 days to 14 to 21 days. The cost of the culture medium for bioconversion was reduced by studying the effect of different growth factors on the biomethanation capability of Mic-1 consortium. Four different bench scale bioreactor configurations, namely Rotating Biological Contactor (RBC), Upflow Fluidized Bed Reactor (UFBR), Trickle Bed Reactor (TBR), and Continuously Stirred Tank Reactor (CSTR) were evaluated for scale up studies. Preliminary results indicated highest biomethanation of TxL by the Mic-1 consortium in the CSTR, and lowest in the trickle bed reactor. However, highest methane production and process efficiency were obtained in the RBC.

Laboratory Constraints on the Stability of Petroleum at Elevated Temperatures: Implications for the Origin of Natural Gas  

SciTech Connect (OSTI)

Results of prior DOE supported research conducted at the Woods Hole Oceanographic Institution have demonstrated the participation of sedimentary minerals and water as reactants and catalysts in chemical transformations associated with the degradation of oil and the formation of low molecular weight organic compounds. The occurrence of such processes in natural environments can be difficult to recognize because the composition of organic alteration products may not be substantially different than those produced by thermal cracking. The goals of this study were the development of diagnostic tools based on hydrogen and carbon isotopes that can be used to identify geochemical processes responsible for the formation of thermogenic natural gas. In addition, our activities were expanded to include experimental investigation of CO2 reduction in aqueous systems at elevated temperature and pressures and an assessment of microbial activity in relatively low temperature (<70°C) natural gas reservoirs in southeastern Oklahoma. Specific objectives included: ? A laboratory investigation of geochemical processes that regulate the hydrogen isotope composition of low molecular weight hydrocarbons in natural gas at elevated temperatures and pressures. ? A laboratory investigation of factors that regulate the carbon isotope composition of organic acids in basinal brines. ? A laboratory assessment of the role of methanol during reduction of CO2 to CH4 under hydrothermal conditions. ? Characterization of microbial ecosystems in coproduced fluids from the Potato Hills gas field to assess the role of microbes in the generation of natural gas.

Near-Zero Emissions Oxy-Combustion Flue Gas Purification Task 2: SOx/Nox/Hg Removal for High Sulfur Coal  

SciTech Connect (OSTI)

The goal of this project is to develop a near-zero emissions flue gas purification technology for existing PC (pulverized coal) power plants that are retrofitted with oxy-combustion technology. The objective of Task 2 of this project was to evaluate an alternative method of SOx, NOx and Hg removal from flue gas produced by burning high sulfur coal in oxy-combustion power plants. The goal of the program was not only to investigate a new method of flue gas purification but also to produce useful acid byproduct streams as an alternative to using a traditional FGD and SCR for flue gas processing. During the project two main constraints were identified that limit the ability of the process to achieve project goals. 1) Due to boiler island corrosion issues >60% of the sulfur must be removed in the boiler island with the use of an FGD. 2) A suitable method could not be found to remove NOx from the concentrated sulfuric acid product, which limits sale-ability of the acid, as well as the NOx removal efficiency of the process. Given the complexity and safety issues inherent in the cycle it is concluded that the acid product would not be directly saleable and, in this case, other flue gas purification schemes are better suited for SOx/NOx/Hg control when burning high sulfur coal, e.g. this project's Task 3 process or a traditional FGD and SCR.

A review of potential turbine technology options for improving the off-design performance of direct coal-fired gas turbines in base load service  

SciTech Connect (OSTI)

The January, 1988 draft topical report, entitled An Assessment of Off-Design Particle Control Performance on Direct Coal-Fired Gas Turbine Systems'' (Ref.1.1), identified the need to assess potential trade-offs in turbine aerodynamic and thermodynamic design which may offer improvements in the performance, operational and maintenance characteristics of open-cycle, direct coal-fired, combustion gas turbines. In this second of a series of three topical reports, an assessment of the technical options posed by the above trade-offs is presented. The assessment is based on the current status of gas turbine technology. Several industry and university experts were contacted to contribute to the study. Literature sources and theoretical considerations are used only to provide additional background and insight to the technology involved.

Simulated coal-gas fueled carbonate fuel cell power plant system verification. Final report, September 1990--June 1995  

SciTech Connect (OSTI)

This report summarizes work performed under U.S. Department of Energy, Morgantown Energy Technology Center (DOE/METC) Contract DE-AC-90MC27168 for September 1990 through March 1995. Energy Research Corporation (ERC), with support from DOE, EPRI, and utilities, has been developing a carbonate fuel cell technology. ERC`s design is a unique direct fuel cell (DFC) which does not need an external fuel reformer. An alliance was formed with a representative group of utilities and, with their input, a commercial entry product was chosen. The first 2 MW demonstration unit was planned and construction begun at Santa Clara, CA. A conceptual design of a 10OMW-Class dual fuel power plant was developed; economics of natural gas versus coal gas use were analyzed. A facility was set up to manufacture 2 MW/yr of carbonate fuel cell stacks. A 100kW-Class subscale power plant was built and several stacks were tested. This power plant has achieved an efficiency of {approximately}50% (LHV) from pipeline natural gas to direct current electricity conversion. Over 6,000 hours of operation including 5,000 cumulative hours of stack operation were demonstrated. One stack was operated on natural gas at 130 kW, which is the highest carbonate fuel cell power produced to date, at 74% fuel utilization, with excellent performance distribution across the stack. In parallel, carbonate fuel cell performance has been improved, component materials have been proven stable with lifetimes projected to 40,000 hours. Matrix strength, electrolyte distribution, and cell decay rate have been improved. Major progress has been achieved in lowering stack cost.

In addition, the PMM estimates capacity expansion and fuel consumption of domestic refineries. The PMM contains a linear programming representation of U.S. refining activities in the five Petroleum Area Defense Districts (PADDs) (Figure 9). The model is created by aggregating individual refineries into one linear programmming representation for each PADD. This representation provides the marginal costs of production for a number of conventional and new petroleum products. In order to interact with other NEMS modules with different regional representations, certain PMM inputs and outputs are converted from PADD regions to other regional structures and vice versa. The linear programming results are used to determine

STEO November 2012 - coal supplies  

U.S. Energy Information Administration (EIA) Indexed Site

Despite drop in domestic coal production, U.S. coal exports to reach Despite drop in domestic coal production, U.S. coal exports to reach record high in 2012. While U.S. coal production is down 7 percent this year due in part to utilities switching to low-priced natural gas to generate electricity, American coal is still finding plenty of buyers in overseas markets. U.S. coal exports are expected to hit a record 125 million tons in 2012, the U.S. Energy Information Administration says in its new monthly short-term energy outlook. Coal exports are expected to decline in 2013, primarily because of continuing economic weakness in Europe, lower international coal prices, and higher coal production in Asia. However, U.S. coal exports next year are still expected to top 100 million tons for the third year in a row

Reducing power production costs by utilizing petroleum coke. Annual report  

SciTech Connect (OSTI)

A Powder River Basin subbituminous coal from the North Antelope mine and a petroleum shot coke were received from Northern States Power Company (NSP) for testing the effects of parent fuel properties on coal-coke blend grindability and evaluating the utility of petroleum coke blending as a strategy for improving electrostatic precipitator (ESP) particulate collection efficiency. Petroleum cokes are generally harder than coals, as indicated by Hardgrove grindability tests. Therefore, the weaker coal component may concentrate in the finer size fractions during the pulverizing of coal-coke blends. The possibility of a coal-coke size fractionation effect is being investigated because it may adversely affect combustion performance, it may enhance ESP particulate collection efficiency. Petroleum cokes contain much higher concentrations of V relative to coals. Consequently, coke blending can significantly increase the V content of fly ash resulting from coal-coke combustion. Pentavalent vanadium oxide (V{sub 2}O{sub 5}) is a known catalyst for transforming gaseous sulfur dioxide (SO{sub 2}[g]) to gaseous sulfur trioxide (SO{sub 3}[g]). The presence of SO{sub 3}(g) strongly affects fly ash resistivity and, thus, ESP performance.

Advanced turbine design for coal-fueled engines. Phase 1, Erosion of turbine hot gas path blading: Final report  

SciTech Connect (OSTI)

The investigators conclude that: (1) Turbine erosion resistance was shown to be improved by a factor of 5 by varying the turbine design. Increasing the number of stages and increasing the mean radius reduces the peak predicted erosion rates for 2-D flows on the blade airfoil from values which are 6 times those of the vane to values of erosion which are comparable to those of the vane airfoils. (2) Turbine erosion was a strong function of airfoil shape depending on particle diameter. Different airfoil shapes for the same turbine operating condition resulted in a factor of 7 change in airfoil erosion for the smallest particles studied (5 micron). (3) Predicted erosion for the various turbines analyzed was a strong function of particle diameter and weaker function of particle density. (4) Three dimensional secondary flows were shown to cause increases in peak and average erosion on the vane and blade airfoils. Additionally, the interblade secondary flows and stationary outer case caused unique erosion patterns which were not obtainable with 2-D analyses. (5) Analysis of the results indicate that hot gas cleanup systems are necessary to achieve acceptable turbine life in direct-fired, coal-fueled systems. In addition, serious consequences arise when hot gas filter systems fail for even short time periods. For a complete failure of the filter system, a 0.030 in. thick corrosion-resistant protective coating on a turbine blade would be eroded at some locations within eight minutes.

ADVANCED FLUE GAS CONDITIONING AS A RETROFIT UPGRADE TO ENHANCE PM COLLECTION FROM COAL-FIRED ELECTRIC UTILITY BOILERS  

SciTech Connect (OSTI)

The U.S. Department of Energy and ADA Environmental Solutions are engaged in a project to develop commercial flue gas conditioning additives. The objective is to develop conditioning agents that can help improve particulate control performance of smaller or under-sized electrostatic precipitators on utility coal-fired boilers. The new chemicals will be used to control both the electrical resistivity and the adhesion or cohesivity of the fly ash. There is a need to provide cost-effective and safer alternatives to traditional flue gas conditioning with SO{sub 3} and ammonia. During this reporting quarter, further laboratory-screening tests of additive formulations were completed. For these tests, the electrostatic tensiometer method was used for determination of fly ash cohesivity. Resistivity was measured for each screening test with a multi-cell laboratory fly ash resistivity furnace constructed for this project. Also during this quarter chemical formulation testing was undertaken to identify stable and compatible resistivity/cohesivity liquid products.

SciTech Connect (OSTI)

Several experiments were conducted to study the efficiency of granulated sludge consortium (GSC) on the biomethanation of Texas lignite (TxL). With an aim of obtaining a better culture than Mic-1, GSC was used as inoculum at different concentrations. The first experiment was conducted under anaerobic conditions in 60-mL vials containing 40 mL 0.01% SNTM + 1% TxL + 10% GSC. Methane production was measured periodically in the vial headspace and after 20 days of incubation, methane was found to be up to 67 mole%. The second experiment was conducted to determine whether methane production was from biogasification of coal or from substrates used for growing the GSC. The effect of two different anaerobic conditions on biomethanation of Texas lignite was also studied.

Partitioning of mercury, arsenic, selenium, boron, and chloride in a full-scale coal combustion process equipped with selective catalytic reduction, electrostatic precipitation, and flue gas desulfurization systems  

SciTech Connect (OSTI)

A full-scale field study was carried out at a 795 MWe coal-fired power plant equipped with selective catalytic reduction (SCR), an electrostatic precipitator (ESP), and wet flue gas desulfurization (FGD) systems to investigate the distribution of selected trace elements (i.e., mercury, arsenic, selenium, boron, and chloride) from coal, FGD reagent slurry, makeup water to flue gas, solid byproduct, and wastewater streams. Flue gases were collected from the SCR outlet, ESP inlet, FGD inlet, and stack. Concurrent with flue gas sampling, coal, bottom ash, economizer ash, and samples from the FGD process were also collected for elemental analysis. By combining plant operation parameters, the overall material balances of selected elements were established. The removal efficiencies of As, Se, Hg, and B by the ESP unit were 88, 56, 17, and 8%, respectively. Only about 2.5% of Cl was condensed and removed from flue gas by fly ash. The FGD process removed over 90% of Cl, 77% of B, 76% of Hg, 30% of Se, and 5% of As. About 90% and 99% of the FGD-removed Hg and Se were associated with gypsum. For B and Cl, over 99% were discharged from the coal combustion process with the wastewater. Mineral trona (trisodium hydrogendicarbonate dehydrate, Na{sub 3}H(CO{sub 3}){sub 2}.2H{sub 2}O) was injected before the ESP unit to control the emission of sulfur trioxide (SO{sub 3}). By comparing the trace elements compositions in the fly ash samples collected from the locations before and after the trona injection, the injection of trona did not show an observable effect on the partitioning behaviors of selenium and arsenic, but it significantly increased the adsorption of mercury onto fly ash. The stack emissions of mercury, boron, selenium, and chloride were for the most part in the gas phase. 47 refs., 3 figs., 11 tabs.

Chapter 8 - Coal Seam Degasification  

Science Journals Connector (OSTI)

Abstract The chapter discusses various techniques for coal seam degasification. All coal seams are gassy but they differ in their degree of gassiness. Pre-mining and post-mining techniques for underground coal mines are discussed. With good planning, 50–80% of in-situ gas in coal can be removed before mining improving both safety and productivity. Similarly, 50–80% of gas from mined-out areas (gobs) can be removed to minimize ventilation air requirements. Gas transport in underground mines and economics of coal seam degasification are also discussed.

Enhanced Elemental Mercury Removal from Coal-fired Flue Gas by Sulfur-chlorine Compounds  

SciTech Connect (OSTI)

Oxidation of Hg0 with any oxidant or converting it to a particle-bound form can facilitate its removal. Two sulfur-chlorine compounds, sulfur dichloride (SCl2) and sulfur monochloride (S2Cl2), were investigated as oxidants for Hg0 by gas phase reaction and by surface-involved reactions in the presence of flyash or activated carbon. The gas phase reaction rate constants between Hg0 and the sulfur/chlorine compounds were determined, and the effects of temperature and the main components in flue gases were studied. The gas phase reaction between Hg0 and SCl2 is shown to be more rapid than the gas phase reaction with chlorine, and the second order rate constant was 9.1(+-0.5) x 10-18 mL-molecules-1cdots-1 at 373oK. Nitric oxide (NO) inhibited the gas phase reaction of Hg0 with sulfur-chlorine compounds. The presence of flyash or powdered activated carbon in flue gas can substantially accelerate the reaction. The predicted Hg0 removal is about 90percent with 5 ppm SCl2 or S2Cl2 and 40 g/m3 of flyash in flue gas. The combination of activated carbon and sulfur-chlorine compounds is an effective alternative. We estimate that co-injection of 3-5 ppm of SCl2 (or S2Cl2) with 2-3 Lb/MMacf of untreated Darco-KB is comparable in efficiency to the injection of 2-3 Lb/MMacf Darco-Hg-LH. Extrapolation of kinetic results also indicates that 90percent of Hg0 can be removed if 3 Lb/MMacf of Darco-KB pretreated with 3percent of SCl2 or S2Cl2 is used. Unlike gas phase reactions, NO exhibited little effect on Hg0 reactions with SCl2 or S2Cl2 on flyash or activated carbon. Mercuric sulfide was identified as one of the principal products of the Hg0/SCl2 or Hg0/S2Cl2 reactions. Additionally, about 8percent of SCl2 or S2Cl2 in aqueous solutions is converted to sulfide ions, which would precipitate mercuric ion from FGD solution.

Enhancing the use of coals by gas reburning-sorbent injection. Environmental monitoring quarterly report No. 8, April 1--June 30, 1992  

SciTech Connect (OSTI)

Clean Coal Technology implies the use of coal in an environmentally acceptable manner. Coal combustion results in the emission of two types of acid rain precursors: oxides of sulfur (sox) and oxides of nitrogen (NO{sub x}). This Clean Coal Technology project will demonstrate a combination of two developed technologies to reduce both NO{sub x} and SO{sub x} emissions. Gas reburning and calcium based dry sorbent injection. The demonstrations will be conducted on two pre-NSPS utility boilers representative of the US boilers which contribute significantly to the inventory of acid rain precursor emissions. Gas reburning is a combustion modification technique that consists of firing 80--85 percent of the fuel (corresponding to the total heat release) in the lower furnace. Reduction of NO{sub x} to molecular nitrogen (N{sub 2}) is accomplished via the downstream injection of the remaining fuel requirement in the form of natural gas (which also reduces the total SO{sub x} emissions). In a third stage, burnout air is injected at lower temperatures in the upper furnace to complete the combustion process without generating significant additional NO{sub x}. Dry sorbent injection consists of injecting calcium based sorbents (such as limestone, dolomite, or hydrated lime) into the combustion products. For sulfation of the sorbent to CaSO{sub 4}, an injection temperature of about 1230{degrees}C is optimum, but calcium-sulfur reactions can also take place at lower temperatures. Thus, the sorbent may be injected at different locations, such as with the burnout air, at the exit from the superheater, or into the ducting downstream of the air heater with H{sub 2}O added for humidification. The specific goal of this project is to demonstrate NO{sub x} and SO{sub x} emission reductions of 60 percent and 50 percent, respectively, on two coal fired utility boilers having the design characteristics mentioned above.

CO2 SEQUESTRATION POTENTIAL OF TEXAS LOW-RANK COALS  

SciTech Connect (OSTI)

The objectives of this project are to evaluate the feasibility of carbon dioxide (CO{sub 2}) sequestration in Texas low-rank coals and to determine the potential for enhanced coalbed methane (CBM) recovery as an added benefit of sequestration. The primary objectives for this reporting period were to construct a coal geological model for reservoir analysis and to continue modeling studies of CO{sub 2} sequestration performance in coalbed methane reservoirs under various operational conditions. Detailed correlation of coal zones is important for reservoir analysis and modeling. Therefore, we interpreted and created isopleth maps of coal occurrences, and correlated individual coal seams within the coal bearing subdivisions of the Wilcox Group--the Hooper, Simsboro and Calvert Bluff formations. Preliminary modeling studies were run to determine if gravity effects would affect the performance of CO{sub 2} sequestration in coalbed methane reservoirs. Results indicated that gravity could adversely affect sweep efficiency and, thus, volumes of CO{sub 2} sequestered and methane produced in thick, vertically continuous coals. Preliminary modeling studies were also run to determine the effect of injection gas composition on sequestration in low-rank coalbeds. Injected gas composition was varied from pure CO{sub 2} to pure N{sub 2}, and results show that increasing N{sub 2} content degrades CO{sub 2} sequestration and methane production performance. We have reached a Data Exchange Agreement with Anadarko Petroleum Corporation. We are currently incorporating the Anadarko data into our work, and expect these data to greatly enhance the accuracy and value of our studies.

Abstract The causality relationship between economic growth and coal, natural gas and oil consumption was investigated using the ARDL (autoregressive distributed lag bounds) testing approach for the 1980–2011 period in Brazil, Russian, India, China, Turkey and South Africa. According to long-run and strong causality results, there is bi-directional causality between oil energy consumption and Y for all countries. The long-run causality and strong causality results between coal consumption and economic growth indicated that there is bi-directional causality for China and India. According to long-run causality results and a strong causality result, there are bi-directional causality relationships between NGC (natural gas energy consumption) and Y for Brazil, Russia and Turkey.

Coal dust explosibility  

Science Journals Connector (OSTI)

This paper reports US Bureau of Mines (USBM) research on the explosibility of coal dusts. The purpose of this work is to improve safety in mining and other industries that process or use coal. Most of the tests were conducted in the USBM 20 litre laboratory explosibility chamber. The laboratory data show relatively good agreement with those from full-scale experimental mine tests. The parameters measured included minimum explosible concentrations, maximum explosion pressures, maximum rates of pressure rise, minimum oxygen concentrations, and amounts of limestone rock dust required to inert the coals. The effects of coal volatility and particle size were evaluated, and particle size was determined to be at least as important as volatility in determining the explosion hazard. For all coals tested, the finest sizes were the most hazardous. The coal dust explosibility data are compared to those of other hydrocarbons, such as polyethylene dust and methane gas, in an attempt to understand better the basics of coal combustion.

Coal: the new black  

SciTech Connect (OSTI)

Long eclipsed by oil and natural gas as a raw material for high-volume chemicals, coal is making a comeback, with oil priced at more than $100 per barrel. It is relatively cheap feedstock for chemicals such as methanol and China is building plants to convert coal to polyolefins on a large scale and interest is spreading worldwide. Over the years several companies in the US and China have made fertilizers via the gasification of coal. Eastman in Tennessee gasifies coal to make methanol which is then converted to acetic acid, acetic anhydride and acetate fiber. The future vision is to convert methanol to olefins. UOP and Lurgi are the major vendors of this technology. These companies are the respective chemical engineering arms of Honeywell and Air Liquide. The article reports developments in China, USA and India on coal-to-chemicals via coal gasification or coal liquefaction. 2 figs., 2 photo.
