    This paper is intended to provide an overview of some of the recent developments in MTBE demand growth worldwide and the impact of these developments on MTBE demand in the future. It provides a perspective of the influence of developments in the US on the worldwide MTBE markets. The public`s outcry regarding oxygenates in gasoline, and specifically MTBE, that has been evolving in the US during the past several months is in response to a politically mandated requirement for a fuel that contains oxygen that is provided by MTBE or ethanol. This public unrest had negatively impacted the market price for MTBE at the time this paper was being prepared. However, the author believes that MTBE, because of its clean octane capabilities, will continue to be used as an octane blendstock for gasoline in increasing quantities worldwide as we move through lead phasedown in West Europe and other countries that are experiencing pollution problems relating to exhaust emissions from internal combustion engines. The objectives of this paper are as follows: review developments in MTBE demand 1990--2000; identify regions where MTBE demand growth will occur; review production growth for MTBE, both historical and forecast; examine world trade patterns during the period; assess methanol demand growth during the period; analyze MTBE`s regional price bias; and provide a forecast of future MTBE price trends.

    Isothermal pyrolysis studies have been conducted on a Green River Formation oil shale from Colorado and a New Albany oil shale from Kentucky. The conversion of kerogen to bitumen, oil, gas, and residue products was obtained for different isothermal reaction times in the temperature range of 375/degree/C to 440/degree/C (707/degree/ to 824/degree/F) using a heated sand bath reactor system. Particular attention was paid to the formation of the bitumen intermediate during decomposition of the two shales. The maximum amount of extractable bitumen in the New Albany shale was 14% or less of the original kerogen at any given temperature, indicating that direct conversion of kerogen to oil, gas, and residue products is a major pathway of conversion of this shale during pyrolysis. In contrast, a significant fraction of the Colorado oil shale kerogen was converted to the intermediate bitumen during pyrolysis. The bitumen data imply that the formation of soluble intermediates may depend on original kerogen structure and may be necessary for producing high yields by pyrolysis. 24 refs., 14 figs., 8 tabs.

    Methyl-tertiary-butyl-ether (MTBE) has become the leading oxygenate in use in the petroleum industry. Since its introduction several years ago there has been premature deterioration of nonmetallic materials in both neat MTBE and MTBE + gasoline. This degradation is costly in several ways: maintenance, replacement, environmental, and product-loss. Identifying nonmetallic materials compatible with MTBE and MTBE + gasoline is important to the petroleum industry -- all the way from the refinery to the retail sale. Exposure tests have been conducted with different types of nonmetallics in neat MTBE, neat MTBE vapor, and 5% MTBE + 95% gasoline. As in previously reported tests, Teflon{reg_sign} laminates were the top performers, experiencing very little change in any of the properties tested. An ester and ether-based urethane laminate also exhibited only small property changes. Most materials displayed significant deterioration of one or more of the measured properties, even in MTBE condensing vapor and the 5% MTBE + 95% gasoline. The specific effects on each material need to be individually evaluated to determine the effect on service life.

    After several months of drifting lower in line with declining autumn gasoline prices, tabs for methyl tert-butyl ether (MTBE) have turned around. There has been no big demand surge, but consumers and traders are beginning to build up inventories in advance of a series of midwinter shutdowns and turnarounds by producers. Spot prices, which dropped as low as 75 cts/gal, have rebounded to 90 cts/gal fob. Eager for a positive glimmer, methanol producers posted a 3-cts/gal increase in contract prices this month. It marks the first upward idea since February. In that time contract prices have dropped 75% from $1.55/gal to 39 cts/gal. A hard winter has hit early in much of the US sending natural gas prices up sharply. At the same time, formaldehyde and acetic acid markets remain firm, and with MTBE rebounding, methanol producers feel entitled to a piece of the action. {open_quotes}I don`t buy into this claim that MTBE demand is up and I don`t think producers can justify even a 3-cts/gal increase,{close_quotes} says one. {open_quotes}There is nothing in the economy to warrant a run-up.

    Methyl tertiary butyl ether (MTBE) is a major and familiar component of Reformulated and Oxygenated gasoline in the US. As such, it is essential to the success of the Clean Air Act programs now reaching a crescendo in major urban areas. In less than ten years, US MTBE capacity has grown from about 4,000 B/D to more than 200,000 B/D. Outside of the USA, its role is less widely understood. Although MTBE markets elsewhere are much less driven by legislation, they have seen the same spectacular growth prospects. Overall, about as much MTBE is used today overseas as in the US. To date, this has to be one of the petrochemical industry`s major success stories. Yet today, the MTBE industry stands at a crossroads, with the direction of future development uncertain at best. DeWitt`s gasoline and oxygenates team has closely observed the ups and downs of this market during most of its turbulent history. In this paper, the authors shall try to set down the major developments and prospects, with the personal familiarity of having been there when things changed. The story begins with a brief historical sketch, leading up to the identification of four critical periods in which major changes took place. The causes of today`s uncertainty lie in all of these stages, and are in a very real sense an example of the ``Law of Unintended consequences.`` Having set the stage, a cautious set of predictions will be put forth. These are neither as promising as proponents would like, nor as unpromising as some would tend to believe.

    Methyl Tertiary Butyl Ether (MTBE) is produced industrially by catalytic reaction between methanol and isobutene. The catalyst that is widely used is an acidic ion exchange resin. This article explores design and economics when sulfuric acid is the catalyst. The profitability of MTBE production depends mainly on the cost of butenes and methhanol. Thus, the example shows MTBE made with a catalyst of sulfuric acid was profitable at a Saudi Arabian location, even though it was not profitable at a U.S. Gulf Coast location.

    Available treatment technologies for methyl tertiary butyl ether (MTBE) contamination in soil, groundwater, and recovered groundwater are reviewed and assessed. MTBE contamination is becoming an important issue due to the increasing prevalence and regulation of this gasoline additive. In addition, MTBE is more soluble and more mobile in groundwater than most hydrocarbons, so it is usually the first gasoline constituent to reach sensitive receptors. Treatment of MTBE is complicated by its Henry`s constant, which is lower than most other gasoline constituents. Furthermore, evidence of biodegradability of MTBE is mixed, and MTBE does not degrade rapidly abiotically. Groundwater pumping is usually employed to contain and collect MTBE-contaminated groundwater, often successfully because of its high aqueous solubility. Air sparging/soil vapor extraction is also successfully employed to treat MTBE, but its effectiveness is reduced by the low Henry`s constant of MTBE. Sparging and other aerobic bioremediation approaches are hampered by the poor biodegradability of MTBE. Oxidation technologies, such as ozone injection, hold promise for rapid in situ remediation of MTBE. Treatment of recovered groundwater contaminated with MTBE is also problematic. MTBE adsorbs poorly to granular activated carbon; advanced oxidation processes are effective on MTBE, but entail high capital and operating costs; bioreactors are of questionable effectiveness on MTBE. Air stripping is usually the most cost-effective treatment technology for MTBE so long as the off gas from the air stripper can be discharged without treatment. However, off gas treatment is expensive, so groundwater is sometimes heated to reduce the requirement for stripping air.

    The DOE Oil Shale Program was restructured in FY84 to implement a 5-year period of basic and applied research in the study of the phenomena involved in oil shale pyrolysis/retorting. The program calls for the study of two reference shales per year for a period of 5 years. Consequently, the program calls for the identification, acquisition, processing, characterization, storage, disbursement, and record keeping for ten reference shales in a period of 5 years. Terra Tek, Inc. received the DOE Reference Shale Sample Bank contract in October, 1985. Two FY86 reference shales have been acquired, processed and stored under inert gas. The Eastern shale, designated E86, was obtained from the Clegg Creek Member of the New Albany Shale at a quarry near Louisville, Kentucky in the first quarter of FY86. The Western shale was obtained from the Exxon Colony Mine, located near Parachute, Colorado, during the first quarter of FY86. Partial distributions of both shales have been made to DOE contractors. Complete descriptions of the reference shale locales, shale processing procedures and analytical characterization are provided in this report. 7 refs., 40 figs.

    Methyl tert-butyl ether (MTBE) producers were looking for a boost from the official New Year`s start of EPA`s reformulated gasoline (RFG) program. But that prospect has been dimmed by an EPA-proposal-in reaction to concerns about RFG prices-to allow states to withdraw from the program. The states that have opted to out make up 5%-6% of the total RFG pool says Arthur Zadronzy, director/government outreach for MTBE producer Arco Chemical. {open_quotes}This is not a major hit, but it is one we have felt,{close_quotes} he says. Despite the state and EPA actions, MTBE producers are not worried about long-term consequences.

    Methyl tert-butyl ether (MTBE) contamination has complicated the remediation of gasoline contaminated sites. Many sites are using biological processes for ground water treatment and would like to apply the same technology to MTBE. However, the efficiency and reliability of MTBE biological treatment is not well documented. The objective of this study was to examine the operational and environmental variables influencing MTBE biotreatment. A fluidized bed reactor was installed at a fuel transfer station and used to treat ground water contaminated with MTBE and gasoline hydrocarbons. A complete set of chemical and operational data was collected during this study and a statistical approach was used to determine what variables were influencing MTBE treatment efficiency. It was found that MTBE treatment was more sensitive to up-set than gasoline hydrocarbon treatment. Events, such as excess iron accumulation, inhibited MTBE treatment, but not hydrocarbon treatment. Multiple regression analysis identified biomass accumulation and temperature as the most important variables controlling the efficiency of MTBE treatment. The influent concentration and loading of hydrocarbons, but not MTBE, also impacted MTBE treatment efficiency. The results of this study suggest guidelines for improving MTBE treatment. Long cell retention times in the reactor are necessary for maintaining MTBE treatment. The onset of nitrification only occurs when long cell retention times have been reached and can be used as an indicator in fixed film reactors that conditions favorable to MTBE treatment exist. Conversely, if the reactor can not nitrify, it is unlikely to have stable MTBE treatment.

    This paper reports that petrochemical manufacturers continue to increase methyl tertiary butyl ether (MTBE) capacity in North America. The action reflects refiners' reformulation of gasoline to help reduce auto emissions. Demand for gasoline blending oxygenates such as MTBE is expected to increase as U.S. refiners reconfigure processing trains to produce fuels meeting requirements of the Clean Air Act amendments of 1990. Recent progress includes plans to build an MTBE plant in Mexico and start-ups of plants on the U.S. Gulf Coast and in Canada.

    Select zeolites with high SiO{sub 2}/Al{sub 2}O{sub 3} ratios were shown to effectively remove methyl tert-butyl ether (MTBE), chloroform, and trichloroethylene (TCE) from water. In laboratory studies using batch sorption equilibria, high Si large-port mordenite and ZSM-5 (silicalite) were found to have sorption properties for MTBE and TCE superior to activated carbon. for example, at an equilibrium solution concentration of 100 {micro}g/L, high Si mordenite retained 8--12x more MTBE than either of two powdered activated carbons used as reference sorbents. Sorption results also highlight the importance of pore size and SiO{sub 2}/Al{sub 2}O{sub 3} ration on contaminant removal efficiencies by zeolites.

    Gasoline with methyl tertiary butyl ether (MTBE) has been sold in the United States since 1979, when it was added to fuels as an octane enhancer after lead was phased out of motor fuels. Recently it has been introduced as a means of reducing carbon monoxide emissions during the winter months in targeted US cities. However, there is concern over health complaints including headaches, dizziness and nausea from residents of some areas. These reports have launched an era of assidious research by scientists and public health officials across the country to learn more about MTBE`s short-term and long-term, and possibly carcinogenic, health effects. New research should help weigh the risk of MTBE as a possible carcinogen and the effectiveness of MTBE-blended fuels in reducing carbon monoxide levels. The question is whether, in minimizing one risk, is another risk - however small - being introduced?

    Approximately three years ago, the people at Diamond Shamrock's Sunray, Texas, refinery recognized a growing demand for high octane super premium unleaded gasoline in their regional marketing area. It was apparent that they would need to change their processing scheme to meet this growing demand. After investigating several options, they decided to install an MTBE (methyl tert-butyl ether) unit upstream of their existing sulfuric acid (H/sub 2/SO/sub 4/) aklylation unit. The new unit would process olefin feed before it entered the alkylation unit. The MTBE unit was expected to improve Diamond Shamrock's gasoline pool in two ways. First, the MTBE would be an additional high octane blending stock for the gasoline pool. Second, the MTBE unit would improve the quality of the olefin stream going to the alkylation unit. Diamond Shamrock brought their MTBE unit onstream in December, 1985. The results of the combined operation exceeded expectations, producing alkylate in excess of 98 RON (Research octane number) and MTBE of 118 RON. These components significantly upgraded the refinery's capability to produce a super premium unleaded gasoline.

    Capacity increased by more than 4.6% when one dynamic matrix multivariable controller began operating in Valero Refining Company`s MTBE production complex in Corpus Christi, Texas. This was on a plant that was already running well above design capacity due to previously made process changes. A single controller was developed to cover an isobutane dehydrogenation (ID) unit and an MTBE reaction and fractionation plant with the intermediate isobutylene surge drum. The overall benefit is realized by a comprehensive constrained multivariable predictive controller that properly handles all sets of limits experienced by the complex, whether limited by the front-end ID or back-end MTBE units. The controller has 20 manipulated, 6 disturbance and 44 controlled variables, and covers widely varying dynamics with settling times ranging from twenty minutes to six hours. The controller executes each minute with a six hour time horizon. A unique achievement is intelligent surge drum level handling by the controller for higher average daily complex capacity as a whole. The ID unit often operates at simultaneous limits on reactor effluent compressor capacity, cold box temperature and hydrogen/hydrocarbon ratio, and the MTBE unit at impurity in butene column overhead as well as impurity in MTBE product. The paper discusses ether production, isobutane dehydrogenation, maximizing production, controller design, and controller performance.

    The Korean government`s strict standard for gasoline sold domestically is expected to have a significant impact on the methyl tert-butyl ether (MTBE) market. The mandate-requiring gasoline oxygen content of 0.5% this year, 0.75% by 1996, and 1.0% by 1998-has sparked a rush by Korean refineries to build new MTBE plants. If expansion plans are carried out, Korea`s MTBE capacity will increase from 280,000 m.t./year to 650,000 m.t./year by 1996, far surpassing predicted demand. Honam Oil, part of the Lucky Group, plans startup of a 100,000-m.t./year unit at Yeochon by early 1996. In addition, by the end of 1996 Ssangyong Oil will bring a 100,000-m.t./year unit onstream.

    Ecofuel (Milan), an ENI company, is evaluating construction of a new methyl tert-butyl ether (MTBE) plant in Italy, but has shelved plans for a world-scale MTBE unit in Mexico. The Italian unit is tied to ethylene expansion now under way. Later this year EniChem (Milan), a sister company, is due to complete construction of a 360,000-m.t./year cracker at Brindisi. The C{sub 4} stream available there and from the existing cracker at Priolo in Sicily should provide enough feed for a unit of up to 100,000 m.t./year of MTBE capacity. Some of the feedstock could also come from the Ravenna cracker.

    After the second winter oxygenated fuels program of the 1990 Clean Air Act, producers of methyl tert-butyl ether (MTBE) are still feeling the chill of poor profitability. Despite the strong demand growth for MTBE to meet oxygen requirements in reformulated gasoline (RFG), oversupply still dogs the market. That, combined with a run-up in feedstock prices, has seen margins for MTBE markers all but evaporate. And it seems matters are likely to get worse before they get better. This week, Belvieu Environmental Fuels (BEF; Houston) expects to startup its 15,000-bbl/day MTBE plant at Mont Belvieu, TX. In late July, Texaco will start up its 15,000-bbl/day MTBE/propylene oxide (PO) plant at Port Neches, TX. In addition, a rash of refinery-based MTBE and tert-amyl methyl ether projects are nearing completion. {open_quotes}Profitability in MTBE has been extremely poor,{close_quotes} says Marvin O. Schlanger, president of Arco Chemical Americas, the largest MTBE producer. There has, however, been some recent recovery on the spot market, with MTBE moving from less than 60 cts/gal to near cash-cost levels of 70 cts/gal. But contract prices remain depressed, and strength in butane and methanol pricing have all buy wiped out any gains in MTBE.

    Methyl tert-butyl ether (MTBE), is made by reacting methanol with isobutylene. The preferred source of isobutylene is a steam cracker C/sub 4/ cut from which butadiene has been removed. However, moving the MTBE synthesis upstream of the butadiene extraction will improve the extraction step. The following is a review of conditions imposed on the MTBE unit's design and operation when placed in this new location.

    This paper has been developed to provide refiners with business decision insight regarding the production of methyl tertiary butyl ether (MTBE) from refinery - (FCC) produced isobutylene. The driving forces making MTBE an attractive investment are examined with regard to the increasing demand for higher octane unleaded gasolines. The decision to proceed with MTBE production depends on the profitability of such an investment and the refiner's ability to meet market demands using available processing equipment, refinery produced streams and external feedstocks. The factors affecting this decision are analyzed in this paper and include: industry ability to meet rising octane demand; profit potential realized by diverting isobutylene to MTBE; availability of technology for producing MTBE; and investment and operating costs required to produce MTBE. Chemical Research and Licensing and NEOCHEM have developed a simple, low cost process to produce MTBE, reducing the excessive equipment and high operating costs that were associated with conventional MTBE designs. The economics and process benefits of installing a CRandL/NEOCHEM MTBE process are examined within the framework of a generalized medium-sized refinery configuration.

    Gas phase synthesis of MTBE from methanol and isobutene has been investigated over different zeolites. It is shown that bulk Si/Al ratio has a marked influence on the formation of MTBE. H-beta zeolite was found to be as active as acid Amberlyst-15 (reference catalyst), and noticeably superior to non- and dealuminated forms of H-Y, H-ZSM-5, zeolite omega, and H-mordenites. Screening test results obtained over other catalysts (SAPOs and pillared clays) are briefly commented. The contribution of the external surface of the zeolites to the reaction is discussed. In the case of H-Y zeolites, it is shown that extra framework Al species ({sup 27}Al NMR signal at 30 ppm) have a detrimental effect on the reaction. 64 refs., 12 figs., 3 tabs.

    Oxygenated and reformulated gasolines have been developed in response to air pollution control regulations targeted at reducing carbon monoxide emissions and photochemical air pollution. The 1990 Clean Air Act Amendments required the addition of fuel oxygenates to gasoline in areas where the level of carbon monoxide exceeded national ambient air quality standards. In the South Coast Air Basin gasoline containing oxygenated compounds has been in use since the late 1980`s. One oxygenated fuel additive most often selected by producers to meet the requirements is methyl tert-butyl ether (MTBE). However, large production numbers associated with MTBE production, combined with the compound`s high water solubility, chemical stability, and toxicity, make it a potentially important groundwater pollutant. The County Sanitation District of Los Angeles, Joint Water Pollution Control Plant in Carson, California is one of the few wastewater treatment plants in the nation that receives refinery wastewater discharge. It has operated several pilot-scale compost-based biofilters for control of various volatile organic contaminants throughout the plant since a 1991 joint study with the University of California, Davis. After one year of operation, one of the biofilters spontaneously developed the ability to degrade MTBE. The paper describes the collaborative efforts to determine the feasibility of transferring the degrading microbial population from the solid to liquid phase, without loss of activity, and to determine some of the environmental requirements necessary for survival of the microbial culture.

    Fuel oxygenates are used in metropolitan areas across the United States in order to reduce the amount of carbon monoxide released into the atmosphere during the winter. The most commonly used fuel oxygenate is Methyl tert-butyl ether (MTBE). Its widespread use has resulted in releases into the environment. To date there has been only minimal effort to investigate ecological impacts caused by exposure to concentrations of MTBE typically found in environmental media. Research into the potential for MTBE to adversely affect ecological receptors is essential. Acquisition of such baselines data is especially critical in light of continuing inputs and potential accumulation of MTBE in environmental media. A research Agenda is included in this report and addresses: Assessing Ecological Impacts, Potential Ecological Impacts of MTBE (aquatic organisms, terrestrial organisms), Potential Ecological Endpoints, and A Summary of Research Needs.

    In order to assess the pathways for human exposure to methyl-tert-butyl-ether (MTBE) and to understand the extent of MTBE contamination in watersheds, a purge and trap gas chromatographic mass spectrometric method to measure part-per-trillion (ppt) concentrations of MTBE in environmental waters was developed. A variety of California's raw drinking waters were analyzed. No detectable MTBE was found in deep groundwater (>1000 feet). However shallow groundwater ({approx}250 feet) contained MTBE concentrations of non-detect to 1300 ppt. MTBE concentrations measured in rivers and lakes ranged from non-detect to 3500 ppt. East (San Francisco) Bay area rain water contained approximately 80 ppt MTBE.

    Implementation of the oxygenated fuels program by EPA in 39 metropolitan areas, including Fairbanks and Anchorage, Alaska, in the winter of 1992, encountered some unexpected difficulties. Complaints of headaches, dizziness, nausea, and irritated eyes started in Fairbanks, jumped to Anchorage, and popped up in various locations in the lower 48 states. The suspected culprit behind these complaints was the main additive for oxygenation of gasoline is methyl tert-butyl ether (MTBE). A test program, hastily organized in response to these complaints, has indicated that MTBE is a safe gasoline additive. However, official certification of the safety of MTBE is still awaited.

    This month's legislated reduction of the allowable amount of lead additives in gasoline will increase demand strongly for methyl-tert-butyl ether (MTBE) as an octane enhancer, but the economics of the refinery business and the likelihood of rapidly increasing high-octane gasoline imports probably will limit the size of the business in coming years. MTBE will be used to fill the octane gap now, but economics and imports of gasoline later on could hold down demand. The limited growth in sales of MTBE is discussed.

    There are many different liquids that contain oxygen which could be blended into gasoline. The ones that have been tried and make the most sense are in the alcohol (R-OH) and ether (R-O-R) chemical family. The alcohols considered are: methanol (MeOH), ethanol (EtOH), tertiary butyl alcohol (TBA). The ethers are: methyl tertiary butyl ether (MTBE), ethyl tertiary butyl ether (ETBE), tertiary amyl methyl ether (TAME), tertiary amyl ethyl ether (TAEE), di-isopropyl ether (DIPE). Of the eight oxygenates listed above, the author describes the five that are still waiting for widespread marketing acceptance (methanol, TBA, TAME, TAEE, and DIPE). He then discusses the two most widely used oxygenates in the US, MTBE and ethanol, along with the up-and-coming ethanol ether, ETBE. Selected physical properties for all of these oxygenates can be found in Table 2 at the end of this paper. A figure shows a simplified alcohol/ether production flow chart for the oxygenates listed above and how they are interrelated.

    Two overlapping dissolved hydrocarbon plumes were identified in the shallow water-bearing zone at a commercial vehicle service and fueling facility. Plume 1 originated from a pre-1993 gasoline product line/dispenser leak. This plume contained a relatively common mix of benzene, toluene, ethylbenzene, xylenes (BTEX), and methyl tert-butyl ether (MTBE); benzene and MTBE were identified as the Plume 1 contaminants of concern based on their detection at approximately 200 {mu}g/l each, which exceeded regulatory guidance. Plume 2, which was detected in the tank cavity during UST removal, resulted from gasoline line leaks/underground storage tank overfills. Although the majority of impacted soils in both the dispenser and tank cavity areas were removed during UST excavation, rainfall during impacted soil removal mobilized the MTBE contained in the soils to groundwater. As a result, Plume 2 contained approximately 900 {mu}g/l MTBE while BTEX compounds were non-detect. Although the impacted zone sustained an approximate yield of only 0.3 gallon per minute, Pennsylvania regulations dictate that this zone must be treated as an aquifer. The failure of remediating gasoline plumes using pump-and-treat has been predominantly due to BTEX`s tendency to adsorb onto soil, creating a residual-phase product layer which acts as a continuing source of dissolved-phase BTEX. Based on this experience, most groundwater and remediation professionals reject pump-and-treat as a viable remedial option, except in situations where controlling groundwater movement is the predominant goal.

    A numerical transport model was used to calculate the movement of methyl-t-butyl ether (MTBE) and several other volatile organic compounds (VOCs) from the atmosphere downward through the unsaturated zone and into shallow groundwater. Simulations were carried out for periods as long as 10 years to investigate whether a gaseous atmospheric MTBE source at typical ambient concentrations could account for the presence of MTBE in shallow groundwater at the types of low ug/L levels that have been found during the National Water Quality Assessment Program currently being conducted by the US Geological Survey. The simulations indicate that downward movement of MTBE to shallow groundwater will be very slow when there is no net downward movement of water through the vadose zone. For example, for a vadose zone composed of fine sand, and assuming tens of cm of infiltration, then only a few years will be required for water at a water table that is 5.0 m below ground surface to attain MTBE levels that correspond to saturation with respect to the atmospheric source gaseous concentration. An on/off atmospheric source, as might occur in the seasonal use of MTBE, will lead to concentrations in shallow groundwater that correspond to saturation with the time-averaging atmospheric source concentration.

    An export-oriented 1-million m.t./year methyl tert-butyl ether (MTBE) plant is planned as one of Iran`s private sector investment projects. State-owned National Petrochemical Co (NPC; Tehran) and the Dubai-based Iranian businessman Abdul Wahab Galadari have signed a letter of intent allowing Galadari to develop the venture. Colt Engineering (Calgary, AL) is assisting Galadari with costs, planning and technology selection for the estimated $300-million plus venture. An important meeting with NPC is scheduled end of this month, says Galadari, and a financial package should be put together by end of March or April. The facility will most likely be wholly-owned by the Galadari family, roughly 50% by members resident in Iran and the remainder by the Dubai-based concern A.W. Galadari Sons. NPC says it may take a token shareholding in the venture.

    Reports and Publications (EIA)

    1999-01-01T23:59:59.000Z

    The blending of methyl tertiary butyl ether (MTBE) into motor gasoline has increased dramatically since it was first produced 20 years ago. MTBE usage grew in the early 1980's in response to octane demand resulting initially from the phaseout of lead from gasoline and later from rising demand for premium gasoline. The oxygenated gasoline program stimulated an increase in MTBE production between 1990 and 1994. MTBE demand increased from 83,000 in 1990 to 161,000 barrels per day in 1994. The reformulated gasoline (RFG) program provided a further boost to oxygenate blending. The MTBE contained in motor gasoline increased to 269,000 barrels per day by 1997.

    This paper reports that refiners and merchant manufacturers in the U.S. are gearing up to produce the large volumes of methyl tertiary butyl ether (MTBE) needed to comply with oxygenated gasoline requirements. The 1990 U.S. Clean Air Act Amendments specify that, as of the first of this coming November, gasoline containing a minimum of 2.7 wt % oxygen must be sold in 39 CO-nonattainment cities. Refiners and others are scurrying to bring MTBE capacity on line in time to meet this requirement. Many U.S. refiners already have some operating MTBE capacity, but this will not be nearly enough to meet the looming increase in demand. As a result, additional capacity is being constructed worldwide.

    Economic evaluation of the methyl tertiary butyl ether (MTBE) complex was carried out starting from n-butane and by captive production of methanol from natural gas. The processing steps consist of isomerization of n-butane to isobutane, dehydrogenation of isobutane to make isobutene, and finally, the reaction of isobutene with methanol to produce MTBE. Two different plant sizes were considered, and the effect of 30% lower feedback prices on profitability was studied. It was found that the raw materials cost is a dominant component, composing about 55% of the total production cost. An internal rate of return of 19% could be realized for 500,000 tons per annum MTBE complex based on economic data in mid-1993. The payback period estimated at this capacity was 3.8 years, and the break-even capacity was 36.6%.

    A GLC-acid extraction method is described for the determination of MTBE in gasolines. The method consists of a programmed GLC analysis starting at about room temperature conducted before and after extraction with cold 85% phosphoric acid. This treatment results in the preferential solubility of ethers and other oxygenated compounds while minimizing the reaction of olefins and aromatics which may be present in the gasolines. Plotting various known concentrations of MTBE in gasolines against the concentrations determined in the same samples by the authors methodology results in a straight line relationship. The concentration of MTBE in any sample of gasoline may thus be determined using their GLC-extraction procedure and the calibration line. The analysis can accommodate a wide choice of standard GLC columns and programs. 2 refs., 1 fig., 1 tab.

    The study of behavior of fixed-bed reactors using ion-exchange resins as catalysts was carried out by making use of a complete bidimensional heterogeneous model for the reactor, which included the resistances inside the ion-exchange resin particles, considered with a macroreticular structure. The active sites were located inside the gel phase of the resin, represented by microspheres, and on the macropores walls. The overall efficiency of such heterogeneous catalyst particles was defined by the macroeffectiveness and microeffectiveness factors accounting for the process behavior on the macropores and inside the microspheres. The synthesis of methyl tert-butyl ether, MTBE, a liquid-phase reversible exothermic reaction between methanol and isobutene, was considered as a reference case. This system was studied in the temperature range of 313--338 K, and the effect of the thermodynamic equilibrium conditions was examined. The results predicted by the complete heterogeneous model were compared with those obtained with the simple pseudohomogeneous model, which revealed higher hot spots. Moreover, a comparison between bidimensional and unidimensional models was also performed. The orthogonal collocation method was used for the discretization of the differential equations inside the catalyst particles, which were reduced from three (corresponding to the three mass balances for the three compounds, isobutene, methanol, and MTBE) to only one differential equation, by using the concept of the generalized variable.

    Synthesis of methyl tert-butyl ether (MTBE) during carbon monoxide (CO) hydrogenation has been studied with the following reaction schemes: (1) the addition of isobutylene during CO hydrogenation over metal catalysts active for methanol synthesis (Pd/SiO{sub 2} and Li-Pd/SiO{sub 2}) and (2) the addition of isobutylene during CO hydrogenation over a dual bed configuration consisting of Li-Pd/SiO{sub 2} and a zeolite (H-ZSM-5 or HY). The addition of isobutylene during methanol synthesis over the supported Pd catalysts indicated that MTBE cannot be formed on metal sites from a reaction of isobutylene with methanol precursors. However, addition of isobutylene to the syngas feed over a dual bed consisting of a methanol synthesis catalyst and an acid zeolite downstream of the methanol synthesis catalyst showed that MTBE can be synthesized during CO hydrogenation provided acid sites are available. In order to get higher conversions of methanol to MTBE, optimization of the acid catalyst and/or reaction conditions would be required to minimize formation of byproduct hydrocarbons.

    Zeolites show interesting properties as catalysts for MTBE synthesis from methanol and isobutene such as a high selectivity to MTBE even at a low methanol/isobutene feed ratio. In order to explain this high selectivity, the adsorption behaviors of HY and HZSM-5 zeolites and their impact on activity and selectivity for MTBE synthesis were studied. Adsorption experiments, carried out under conditions similar to those used for reaction, showed that ca. 2.5 molecules of methanol were adsorbed per acid site on HZSM-5 and HY zeolites, whereas isobutene was found to form a 1:1 adsorption complex. The excess methanol adsorbed was found to be only weakly bonded, probably via hydrogen bonds. On a commercially used resin catalyst (Amberlyst-15) equal amounts of methanol and isobutene were adsorbed. The higher methanol uptake of the zeolites was paralleled by a higher selectivity to MTBE as compared to the resin catalyst. The increased adsorption of methanol on the zeolites was concluded to play a key role in suppressing the formation of by-products due to isobutene dimerization or oligomerization by decreasing the adsorption of isobutene on the active sites and thereby keeping these sites available for reaction. 40 refs., 5 figs., 3 tabs.

    Considered as new bulk petrochemicals of limited feedstocks MTBE (methyltertbutylether) and TAME (tertamylmethylether) need cheap and simple, minimum-cost production processes. The problems in optimizing the etherification are set by specifications for ether products and hydrocarbon raffinates. Working up reaction products from etherification processes containing hydrocarbons, methanol and ether to secure the pure main and side products is difficult because of azeotrope formation of methanol with ethers or hydrocarbons. At EC Erdolchemie GmbH, Cologne, a semicommercial unit with a capacity of 2,500 metric t/y has now been successfully operated for nearly one year producing high purity MTBE (> 99 wt.%) and a raffinate II with methanol content of < 0.05 wt.%. The TAME process has successfully been tested in a 3,000 kg/y TAME pilot plant for almost two years. Based on the operating experience, EC has prepared the engineering for a commercial multiproduct plant, including the production of 30,000 metric t/y MTBE, 15,000 metric t/y TAME and 6,000 metric t/y methylbutenes (TAME cracking product) in the first stage. EC has made application to the authorities for a construction permit. The process for MTBE and TAME will be licensed by EC Erdolchemie GmbH, Postfach 75 20 02, 5000 Cologne 71, West Germany or by Lurgi Kohle und Mineraloltechnik GmbH, Postfach 11 12 31, 6000 Frankfurt Main 2, West Germany.

    Two case studies are discussed in which groundwater pumping reduced levels of dissolved methyl tertiary butyl ether (MTBE) in groundwater by more than two orders of magnitude, in some cases to below detection limits. MTBE contamination in groundwater is becoming an important issue due to the increasing prevalence and regulation of this gasoline additive. In addition, MTBE is more mobile in groundwater than most hydrocarbons, so it is usually the first gasoline constituent to reach sensitive receptors. Since its Henry`s constant is low, in situ removal of MTBE from groundwater by air sparging is slow, and MTBE does not rapidly degrade, either biologically or abiotically. Therefore, groundwater pumping is usually employed to contain and collect MTBE-contaminated groundwater. Pumping groundwater can reduce MME levels to below detection limits within a few years, because MTBE in the subsurface is found mostly dissolved in groundwater. In contrast, the more hydrophobic gasoline hydrocarbons exist mostly in pockets of separate phase material and adsorbed to soil particles and dissolve slowly in groundwater. Hydrocarbon concentrations are rarely reduced to closure levels within a reasonable time frame by pumping. Sites in eastern Massachusetts and southern New Jersey, where groundwater was contaminated with MTBE due to releases of unleaded gasoline from underground storage tanks, are discussed. At these sites, average MTBE levels were reduced by two to three orders of magnitude, from several ppm or more to less than 10 ppb within three years by pumping groundwater at 10 to 30 gpm.

    This paper reports that the advent of methyl tertiary butyl ether (MTBE) as the primary oxygenate blending component for oxygenated and reformulated motor fuels promises significant benefits for the U.S. gas-processing industry. Increased demand for isobutane as MTBE-plant feedstock will buoy both normal butane and isobutane pricing in U.S. gulf Coast during the 1990s. Elimination of the need to crack normal butane in U.S. olefin plants will also strengthen competitive feedstocks somewhat, including ethane and propane. And increased use of normal butane as isomerization feedstock will result in wider recognition of the premium quality of gas plant normal butane production compared to most refinery C[sub 4] production.

Funding for the project has been approved, rights-of-way are secured, and procurement of materials is under way, according to Teppco. The line will flow from the western edge of Shell's refinery eastward to storage facilities of Teppco's Baytown terminal. The shuttle pipeline anticipates the US requirement for oxygenated gasolines that takes effect Nov. 1. Approximately 70% of the available US merchant capacity for MTBE is located along the shuttle's path, Teppco says.

    Rising demand for methyl tertiary butyl ether (MTBE) has spawned interest in finding a cost-effective means of increasing production from existing units. A commercial trial of an improved MTBE catalyst was conducted recently at Lyondell Petrochemical Co.'s Channelview, Tex., plant. The new catalyst called Amberlyst 35 Wet, enhanced oxygenate production in the Lyondell trial. The new catalyst changes the activity coefficients of at least one of the components of the MTBE reaction, resulting in higher equilibrium conversion relative to its first-generation counterpart. Key catalyst properties are: particle size, 0.4--1.25 mm; Apparent density, 0.82 g/ml; Surface area, 44 sq m/g; Moisture content, 56%; Concentration of acid sites, 1.9 meq/ml (5.4 meq/g); Porosity, 0.35 cc/g; and Average pore diameter, 300 [angstrom]. Suggested operating conditions are: maximum temperature, 284 F (140 C); minimum bed depth, 24 in. (0.61 m); and liquid hourly space velocity (LHSV), 1--5 hr[sup [minus]1].

    The US Environmental Protection Agency (USEPA) has tentatively classified MTBE as a possible human carcinogen, thus further emphasizing the importance for study of fate, transport, and environmental effects of MTBE. The treatment of subsurface contaminants (e.g., MTBE) from leaking underground storage tank (LUST) sites presents many complex challenges. Many techniques have been employed for the remediation of contaminants in soil and groundwater at LUST sites. Under sponsorship of US EPA's National Risk Management Research Laboratory, IT Corporation has conducted evaluations of chemical oxidation of MTBE contaminated soil using Fenton's Reagent (hydrogen peroxide catalyzed by ferrous sulfate), simulating both ex-situ and in-situ soil remediation. Bench-scale ex-situ tests have shown up to 90% degradation of MTBE within 12 hours. Pilot-scale MTBE oxidation tests were conducted in a stainless paddle-type mixer with a 10 cubic foot mixing volume. The reactor was designed with a heavy duty mixer shaft assembly to homogenize soil and included provisions for contaminant and reagent addition, mixing, and sample acquisition. The tests were performed by placing 400 pounds of a synthetic soil matrix (consisting of a mixture of top soil, sand, gravel and clay) in the reactor, spiking with 20 ppm of MTBE, and mixing thoroughly. The variables evaluated in the pilot-scale tests included reaction time, amount of hydrogen peroxide, and amount of ferrous sulfate. After 8 hours of reaction, using 4 times the stoichiometric quantity of hydrogen peroxide and a 10:1 hydrogen peroxide: ferrous iron weight ratio, approximately 60% MTBE degradation was observed. When 10 times the stoichiometric quantity of hydrogen peroxide was used (with the same ratio of hydrogen peroxide to ferrous iron), 90% MTBE degradation was observed. When the same test was performed without any ferrous iron addition, 75% MTBE degradation was observed.

    The gasoline additive methyl tert-butyl ether (MTBE) was detected in 24% of water samples collected from surficial and bedrock aquifers in areas of New England. MTBE was the most frequently detected volatile organic compound among the 60 volatile chemicals analyzed and was present in 33 of 133 wells sampled from July 1993 through September 1995. The median MTBE concentration measured in ground-water samples was 0.45 microgram per liter and concentrations ranged from 0.2 to 5.8 microgram per liter. The network of wells sampled for MTBE consisted of 103 monitoring wells screened in surficial sand-and-gravel aquifers and 30 domestic-supply wells in fractured crystalline bedrock aquifers. Seventy-seven percent of all MTBE detections were from 26 shallow monitoring wells screened in surficial aquifers. MTBE was detected in42% of monitoring wells in urban areas. In agricultural areas, MTBE was detected i 8% (2 of 24) of wells and was not detected in undeveloped areas. Sixty-two percent of the MTBE detections in surficial aquifers were from wells within 0.25 mile of gasoline stations or underground gasoline storage tanks; all but one of these wells were in Connecticut and Massachusetts, where reformulated gasoline is used. MTBE was detected in 23% of deep domestic-supply wells that tapped fractured bedrock aquifers. MTBE was detected in bedrock wells only in Connecticut and Massachusetts; land use near the wells was suburban to rural, and none of the sampled bedrock wells were within 0.25 mile of a gasoline station.

    Near infrared (NIR) spectroscopy has emerged as a superior technique for the on-line determination of octane during the blending of gasoline. This results from the numerous advantages that NIR spectroscopy has over conventional on-line instrumentation. Methyl t-butyl ether (MTBE) is currently the oxygenated blending component of choice. MTBE is advantageous because it has a high blending octane, a low Reid vapor pressure, is relatively cheap, and does not form peroxides (1). The goal of this project was to develop a NIR regression model that could be used to predict pump octanes regardless of whether they contained MTBE.

    1987-01-01T23:59:59.000Z

    The refiner today has to evaluate every available option to increase octane in the gasoline pool to make up for the loss in octane created by lead phase down. Production of MTBE is one of the most attractive options. MTBE is produced by selectivity reacting isobutylene with methanol. Valero Refining's refinery at Corpus Christie, Texas (formerly Saber Refining) is one of the most modern refineries built in the last decade to upgrade resids. As part of the gasoline upgrading Valero had built a Butamer Unit to convert normal butane to isobutane upstream of their HF Alkylation Unit. In 1984 as an ongoing optimization of its operations, Valero Refining evaluated various processes to enable it to increase the octane output, and decided to build an MTBE unit. Valero selected the MTBE process licensed by Arco Technology, Inc. and contracted with Jacobs Engineering Group, Inc., Houston, Texas to provide detailed engineering and procurement services.

    Driven by the hot growth prospects for methyl tert-butyl ether (MTBE), Lyondell Petrochemical (Houston) has developed a route to isobutylene it claims can produce the MTBE feedstock at half the capital cost of alternative synthesis technology. If proved, the process will be used in a new 7500-10,000 bbl/day MTBE plant at Channelview, TX. Lyondell also hopes to license the technology. {open_quotes}With expanding MTBE capacity, we will have to have new routes to isobutylene,{close_quotes} says Bob G. Gower, president and CEO of Lyondell. {open_quotes}We think this is a good fit within Lyondell, but also that it is important technology.{close_quotes} Gower declines to detail its specifics, but says it is a one-step isomerization of n-butenes to isobutylene. The firm has tested the process at a pilot unit and plans a demonstration unit in 1992.

    Attached garages have been identified as important sources of indoor residential air pollution. However, the literature lacks information on how the proximity of cars to the living area affects indoor concentrations of gasoline-related compounds, and the origin of these pollutants. We analyzed data from the Relationships of Indoor, Outdoor, and Personal Air (RIOPA) study and evaluated 114 residences with cars in an attached garage, detached garage or carport, or without cars. Results indicate that homes with cars in attached garages were affected the most. Concentrations in homes with cars in detached garages and residences without cars were similar. The contribution from gasoline-related sources to indoor benzene and MTBE concentrations appeared to be dominated by car exhaust, or a combination of tailpipe and gasoline vapor emissions. Residing in a home with an attached garage could lead to benzene exposures ten times higher than exposures from commuting in heavy traffic.

    Capacity increased by more than 4.6% when one dynamic matrix controller began operating in Valero Refining Company`s MTBE production complex in Corpus Christi, Texas. This was on a plant that was already running well above design capacity due to process changes previously made on the plant. A single controller was developed to cover an Oleflex{trademark} isobutane dehydrogenation unit and an MTBe reaction and fractionation plant with the intermediate isobutylene surge drum. The overall benefit is realized by a comprehensive constrained multivariable predictive controller which properly handles all sets of limits experienced by the complex, whether limited by the front-end Oleflex{trademark} or back-end MTBE unit. The controller has 20 manipulated, 6 disturbance and 44 controlled variables, and covers widely varying dynamics with settling times ranging from twenty minutes to six hours. The controller executes each minute with a six hour time horizon. A unique achievement is intelligent handling of the surge drum level by the controller for higher average daily capacity of the complex as a whole. The Oleflex{trademark} often operates at simultaneous limits on reactor effluent compressor capacity, cold box temperature and hydrogen/hydrocarbon ratio and the MTBE at impurity in butene column overhead as well as impurity in MTBE product.

    A pilot scale trickling filter was constructed using granular activated carbon (GAC) as the packing medium and inoculated with a microbial culture known to degrade MTBE. The packing dimensions were 0.076 m in diameter and 0.22 m deep. The unit operated with recycling flow for two months before a biofilm was observed on the GAC. After two additional months the biofilm had visibly spread throughout the packing. A few pieces of GAC were placed in a sealed bottle with MTBE-contaminated water and nutrients. Headspace analysis performed over 14 days confirmed that MTBE degradation was occurring. The trickling filter was converted to continuous flow and operated for one month at a nominal flow rate of 0.1 L/min and a hydraulic loading rate of 32 m{sup 3}/m{sup 2}-d. Samples were collected for analysis at the spray nozzle and at the bottom of the trickling filter. Fractional removal varied with influent MTBE concentration, temperature and liquid flow rate. Percent MTBE removal was as high as 85%. A mechanical failure resulted in the trickling filter bed drying and percent removal dropping to less than 1 percent. However, the system recovered within five days.

    The relationship between MBE-blended gasoline properties and warm-up driveability is investigated by focusing on the transient combustion air-fuel ratio that strongly relates to the combustion state of the engine. As a result, although warm-up driveability of MTBE-free gasoline has a high correlation with 50% distillation temperature (T50) and a high correlation with 100 C distillation volume (E100), the correlation is found to be low when blended with MTBE. Various formulas that improve correlation with peak excess air ratio ({lambda}) by correcting T50 and E100 for the amount of MTBE blended are examined. The formula for which the highest determination coefficient is obtained is proposed as a new driveability index (DI) that can also be applied to MTBE-blended gasoline. In addition, the effect on driveability by gasoline base materials using this new DI also is investigated. The results indicate that the new DI worsen when heavy reformate containing large amounts of aromatics or MTBE, an oxygen-containing compound, is used for the octane improver, leaving the balance of the volatility out of consideration.

    Due to the recent amendment of the Clean Air Act, oxygenates are now being added to gasolines to boost octane and reduce air pollution from combustion in heavily populated areas. Oxygenates such as alcohols (i.e. methanol) and ethers (methyl-tertiary-butyl ether, MTBE) are commonly being used. A series of bioassay studies have been conducted with MTBE, one of the most commonly used octane-enhancing additives. Freshwater and marine studies were conducted with fish, invertebrates and algae to determine the impact of this material on the environment following accidental spills. Static-renewal studies were run to ensure maintenance of MTBE, a highly volatile material in the test containers. Chemical confirmation of exposure concentrations demonstrated the adequacy of the exposure system. Mysid shrimp were highly sensitive to MTBE, with significantly less effect observed with the other species evaluated. These data have implications for spill response, particularly since MTBE is slow to biodegrade and will rapidly move through groundwater. Comparative data for other oxygenates will also be discussed.

    This paper presents data on the differences in energy consumption in the production of leaded and unleaded AI-93 gasolines with various blend components. The authors investigate as high-octane components certain products that are more effective in use and less energy-consuming in production in comparison with alkylate. In particular, methyl tert-butyl ether (MTBE) is discussed; it is not poisonous, it has a high heat of combustion, and it does not attack materials of construction. The addition of 11% MTBE to gasoline lowers the cold start temperature of engines by 10-12 degrees. Moreover, no adjustment of the carburetor is required for the changeover to gasoline with 11% MTBE.

    Microorganisms indigenous to the stream-bed sediments at two gasoline-contaminated groundwater sites demonstrated significant mineralization of the fuel oxygenates, methyl tert-butyl ether (MTBE) and tert-butyl alcohol (TBA). Up to 73% of [U-{sup 14}C]-MTBE and 84% of [U-{sup 14}C]-TBA were degraded to {sup 14}CO{sub 2} under mixed aerobic/anaerobic conditions. No significant mineralization was observed under strictly anaerobic conditions. The results indicate that, under the mixed aerobic/anaerobic conditions characteristic of stream-bed sediments, microbial processes may provide a significant environmental sink for MTBE and TBA delivered to surface water bodies by contaminated groundwater or by other sources.

    Methyl tert-butyl ether (MTBE) has been shown to be specifically anti-angiogenic in piscine and mammalian model systems at concentrations that appear non-toxic in other organ systems. The mechanism by which MTBE targets developing vascular structures is unknown. A global transcriptome analysis of zebrafish embryos developmentally exposed to 0.006255 mM MTBE suggested that hypoxia inducible factor (HIF)-regulated pathways were affected. HIF-driven angiogenesis via vascular endothelial growth factor (vegf) is essential to the developing vasculature of an embryo. Three rescue studies were designed to rescue MTBE-induced vascular lesions: pooled blood in the common cardinal vein (CCV), cranial hemorrhages (CH), and abnormal intersegmental vessels (ISV), and test the hypothesis that MTBE toxicity was HIFVegf dependent. First, zebrafish vegf-a over-expression via plasmid injection, resulted in significantly fewer CH and ISV lesions, 46 and 35% respectively, in embryos exposed to 10 mM MTBE. Then HIF degradation was inhibited in two ways. Chemical rescue by N-oxaloylglycine significantly reduced CCV and CH lesions by 30 and 32% in 10 mM exposed embryos, and ISV lesions were reduced 24% in 5 mM exposed zebrafish. Finally, a morpholino designed to knock-down ubiquitin associated von HippelLindau protein, significantly reduced CCV lesions by 35% in 10 mM exposed embryos. In addition, expression of some angiogenesis related genes altered by MTBE exposure were rescued. These studies demonstrated that MTBE vascular toxicity is mediated by a down regulation of HIFVegf driven angiogenesis. The selective toxicity of MTBE toward developing vasculature makes it a potentially useful chemical in the designing of new drugs or in elucidating roles for specific angiogenic proteins in future studies of vascular development. - Highlights: Global gene expression of MTBE exposed zebrafish suggested altered HIF1 signaling. Over expression of zebrafish vegf-a rescues MTBE-induced vascular lesions. Inhibiting PHD or knocking down VHL rescues MTBE-induced vascular lesions. HIF1-Vegf driven angiogenesis is a target for MTBE vascular toxicity.

    The effects of temperature and acidic pretreatment on Fenton-driven chemical oxidation of methyl tert-butyl ether (MTBE)-spent granular activated carbon (GAC, derived from bituminous coal) were investigated. Limiting factors in MTBE removal in GAC include the heterogeneous distribution of amended Fe, and slow intraparticle diffusive transport of MTBE and hydrogen peroxide (H{sub 2}O{sub 2}) into the 'reactive zone'. Acid pretreatment of GAC before Fe amendment altered the surface chemistry of the GAC, lowered the pH point of zero charge, and resulted in greater penetration and more uniform distribution of Fe in GAC. This led to a condition where Fe, MTBE, and H{sub 2}O{sub 2} coexisted over a larger volume of the GAC contributing to greater MTBE oxidation and removal. H{sub 2}O{sub 2} reaction and MTBE removal in GAC increased with temperature. Modeling H{sub 2}O{sub 2} transport and reaction in GAC indicated that H{sub 2}O{sub 2} penetration was inversely proportional with temperature and tortuosity, and occurred over a larger fraction of the total volume of small GAC particles (0.3 mm diameter) relative to large particles (1.2 mm diameter). Acidic pretreatment of GAC, Fe-amendment, elevated reaction temperature, and use of small GAC particles are operational parameters that improve Fenton-driven oxidation of MTBE in GAC. 29 refs., 6 figs., 1 tab.

    The 1990 Clean Air Act Amendments mandate the addition of oxygenates to gasoline products to abate air pollution. Currently, many areas of the country utilize oxygenated or reformulated fuel containing 15- percent and I I-percent MTBE by volume, respectively. This increased use of MTBE in gasoline products has resulted in accidental point source releases of MTBE containing gasoline products to ground water. Recent studies have shown MTBE to be frequently detected in samples of shallow ground water from urban areas throughout the United States (Squillace et al., 1995). Knowledge of the subsurface fate and transport of MTBE in ground water at leaking underground fuel tank (LUFT) sites and the spatial extent of MTBE plumes is needed to address these releases. The goal of this research is to utilize data from a large number of LUFT sites to gain insights into the fate, transport, and spatial extent of MTBE plumes. Specific goals include defining the spatial configuration of dissolved MTBE plumes, evaluating plume stability or degradation over time, evaluating the impact of point source releases of MTBE to ground water, and attempting to identify the controlling factors influencing the magnitude and extent of the MTBE plumes. We are examining the relationships between dissolved TPH, BTEX, and MTBE plumes at LUFT sites using parallel approaches of best professional judgment and a computer-aided plume model fitting procedure to determine plume parameters. Here we present our initial results comparing dissolved benzene and MTBE plumes lengths, the statistical significance of these results, and configuration of benzene and MTBE plumes at individual LUFT sites.

    Fenton-driven chemical oxidation of methyl tert-butyl ether (MTBE)-spent granular activated carbon (GAC) was accomplished through the addition of iron (Fe) and hydrogen peroxide (H{sub 2}O{sub 2}) (15.9 g/L; pH 3). The GAC used was URV, a bituminous-coal based carbon. The Fe concentration in GAC was incrementally varied (1020-25 660 mg/kg) by the addition of increasing concentrations of Fe solution (FeSO4{center_dot}7H{sub 2}O). MTBE degradation in Fe-amended GAC increased by an order of magnitude over Fe-unamended GAC and H{sub 2}O{sub 2} reaction was predominantly (99%) attributed to GAC-bound Fe within the porous structure of the GAC. Imaging and microanalysis of GAC particles indicated limited penetration of Fe into GAC. The optimal Fe concentration was 6710 mg/kg (1020 mg/kg background; 5690 mg/kg amended Fe) and resulted in the greatest MTBE removal and maximum Fe loading oxidation efficiency (MTBE oxidized (g)/Fe loaded to GAC(mg/Kg)). At lower Fe concentrations, the H{sub 2}O{sub 2} reaction was Fe limited. At higher Fe concentrations, the H{sub 2}O{sub 2} reaction was not entirely Fe limited, and reductions in GAC surface area, GAC pore volume, MTBE adsorption, and Fe loading oxidation efficiency were measured. Results are consistent with nonuniform distribution of Fe, pore blockage in H{sub 2}O{sub 2} transport, unavailable Fe, and limitations in H{sub 2}O{sub 2} diffusive transport, and emphasize the importance of optimal Fe loading. 22 refs., 6 figs., 2 tabs.

    This paper reports a study of the location of Methyl Tertiary Butyl Ether (MTBE) and toluene molecules adsorbed in the pores of the organophylic zeolite mordenite from an aqueous solution. The presence of these organic molecules in the zeolite channels was revealed by structure refinement performed by the Rietveld method. About 3 molecules of MTBE and 3.6 molecules of toluene per unit cell were incorporated into the cavities of mordenite, representing 75% and 80% of the total absorption capacity of this zeolite. In both cases a water molecule was localized inside the side pocket of mordenite. The saturation capacity determined by the adsorption isotherms, obtained by batch experiments, and the weight loss given by thermogravimetric (TG) analyses were in very good agreement with these values. The interatomic distances obtained after the structural refinements suggest MTBE could be connected to the framework through a water molecule, while toluene could be bonded to framework oxygen atoms. The rapid and high adsorption of these hydrocarbons into the organophylic mordenite zeolite makes this cheap and environmental friendly material a suitable candidate for the removal of these pollutants from water. - graphical abstract: Location of MTBE (a) and toluene (b) in mordenite channels (projection along the [001] direction).

    Methyl tert-butyl ether (MTBE) is commonly found at concentrations above the current U.S. Environmental Protection Agency draft lifetime health advisory for drinking water (20 to 200 micrograms per liter) at many point-source gasoline release sites. MTBE is significantly more persistent than benzene, toluene, ethyl-benzene and xylenes (BTEX) in the subsurface. Therefore, evaluation of the implications of its presence in gasoline to monitored natural attenuation and engineered bioremediation alternatives is warranted. An interdisciplinary, field-based investigation of the subsurface transport and fate of MTBE and petroleum hydrocarbons is being conducted by the U.S. Geological Survey (USGS) Toxic Substances Hydrology Program at the site of an underground gasoline storage-tank release near Beaufort, South Carolina. The objective of the investigation is to provide a systematic evaluation of natural attenuation of MTBE compared to BTEX. Results of the field and laboratory studies at this site will be generalized to a broader range of hydrogeochemical conditions through experiments at other sites. Furthermore, newly developed methods of analysis can be applied to sites across the Nation. This investigation of MTBE at point-source release sites is coordinated with investigations of the occurrence of MTBE in shallow ground water, surface water, precipitation, and the atmosphere being conducted by the USGS National Water-Quality Assessment Program.

    At present, the state of knowledge on effective treatment technologies for MtBE in drinking water, and groundwater in general, is limited. Research by others is focusing on the remediation of MtBE close to the point of release. The City of Santa Monica, MWD, Komex and USC are currently conducting research into different technologies that could be used to remove MtBE from drinking water supplies. The objectives of the research are to evaluate different treatment technologies to identify cost-effective and technically feasible alternatives for the removal of MtBE from drinking water. The evaluation is considering moderate to high water flow rates (100 to 2,000+ gpm) and low to moderate MtBE concentrations (<2,000 {mu}g/l). The research program includes four phases: (1) Literature Review; (2) Bench Scale Study; (3) Field Scale Pre-pilot Study; and (4) Summary Evaluation. This paper presents some preliminary information and findings from the first phase of this research - the literature review. The review discusses the chemical properties of MtBE and how they affect remediation and thus, an evaluation of alternative treatment technologies. The review of available literature, and the applicability and limitations of the following technologies are presented in detail.

    Texaco Chemical Co. is building a $400 + million facility to produce 1.2 billion lb/year (14,000 b/d) methyl tertiary butyl ether (MTBE) and 400 million lb/year (about 500 metric tons/day) propylene oxide (PO). The facility-under construction at Port Neches, Tex.-will utilize a newly developed Texaco process that coproduces the two chemicals. The process produces propylene oxide and tertiary butyl alcohol (TBA) from the reaction of isobutane with oxygen in one step, then in a second step with propylene. The TBA is then reacted with methanol in a one-step process that synthesizes MTBE. The paper describes the Port Neches facilities, construction schedule, feedstocks, product uses, and auxiliary equipment.

    The gas phase synthesis of MTBE (methyl tert-butyl ether) was studied using three series of triflic acid (TFA)-modified zeolites, the parent materials being HY, H-mordenite, and HZSM-5. Impregnation with TFA was found to enhance MTBE synthesis activity only for the large-pore zeolite Y and only up to a certain extent of modification. A high level of TFA modification caused a reduction in activity, apparently due to blockage of the active sites by TFA molecules and extra-lattice Al formed during the modification process. The mechanism of activity enhancement by TFA modification appears to be related to the formation of extra-lattice Al rather than the direct presence of TFA. 20 refs., 6 figs., 1 tab.

    The recent realization that oxygenated fuel additives such as MTBE are becoming widely distributed groundwater contaminants has created a sudden and pressing demand for data on the processes that control their environmental fate. Explaining and predicting the subsequent environmental fate of these compounds is going to require extrapolations over long time frames that will be very sensitive to the quality of input data on each compound. To provide such data, they have initiated a systematic study of the pathways and kinetics of fuel oxygenate degradation under subsurface conditions. Batch experiments in simplified model systems are being performed to isolate specific processes that may contribute to MTBE degradation. A variety of degradation pathways can be envisioned that lead to t-butyl alcohol (TBA) as the primary or secondary product. However, experiments to date with a facultative iron reducing bacteria showed no evidence for TBA formation. Continuing experiments include mixed cultures from a range of aquifer materials representative of NAWQA study sites.

  19. Remediation of a fractured clay soil contaminated with gasoline containing MTBE

    Gasoline and other light non-aqueous phase liquids (LNAPLs) released into fractured clay soils initially move by advection of the LNAPL through the fractures. Once advective movement of the LNAPL ceases, dissolution of the gasoline components into the pore water and diffusion into the intact blocks of clay becomes an important transport process. The aqueous-phase flux of each compound in the mixture depends in large part upon its aqueous solubility. For example, a low-solubility compound like isooctane remains primarily in the fracture in the LNAPL. A high-solubility compound, like methyl-tert-butyl ether (MTBE), dissolves readily and may move almost entirely into the clay matrix. The distribution of compounds between the matrix and the fractures will have an important impact on the rate at which the gasoline contaminated soil can be remediated. In this context, the presence of soluble additives like MTBE can significantly impact the risk and remediation time for the, soil. Beginning in 1993 a field study to examine the applicability of air flushing for remediation of low-permeability soils was sponsored by API. The study focused on a variety of soil vapor extraction (SVE) and in situ air sparging (IAS) approaches for mass removal and risk reduction. The source of gasoline contamination in this study was a release of 50 liters of a mixture containing 14 gasoline hydrocarbons ranging from pentane to naphthalene, and including MTBE. The mixture was released into the shallow subsurface and allowed to redistribute for 10 months prior to air flushing startup. Numerical modeling indicated that essentially all of the MTBE should have dissolved into the matrix. In contrast, essentially all of the isooctane should have remained in the LNAPL in the fractures.

    In the summer of 1996, the City of Santa Monica ceased pumping groundwater from two Well Fields (Charnock and Arcadia) used for public drinking water supply due to persistent and increasing concentrations of MtBE in all seven municipal water supply wells. This lost production accounted for 50% of the City`s total drinking water supply. In late 1996, the City, in cooperation with State and Federal agencies, initiated an investigation of MtBE contamination at the two well fields. The objectives of the investigation were as follows: (1) Review available data on the production, use, chemical characteristics, fate and transport, toxicology, and remediation of MtBE; (2) Identify locations of potential sources of MtBE groundwater contamination at the well fields; (3) Develop an understanding of the hydrologic pathways from the potential sources to the drinking water wells; and (4) Evaluate alternative treatment technologies for the removal of MtBE from drinking water. In addition to a review of available information about MtBE, the investigation included an extensive review of literature and available data relevant to the well fields, including well field production histories, site and regional hydrogeology, all well logs and production in the groundwater basins, general groundwater quality, and the record of MtBE detection. Based upon the review of background information, conceptual hydrogeologic models were developed. A detailed review of agency files for over 45 potential source sites was conducted. The information from this review was summarized, and source site screening and ranking criteria were developed. A field program was conducted at the major well field (Charnock), including soil gas surveys, CPTs, soil borings and well installations, geophysics, and aquifer testing. The field program provided site data which allowed the conceptual hydrogeologic model to be refitted to actual site conditions.

Data was obtained for two different dates. The digital numbers of each Landsat scene were converted to radiance and the temperature was calculated in degrees Kelvin and then converted to degrees Celsius for each land cover type using the emissivity of that cover type. And this process was repeated for each of the land cover types (open water, barren, deciduous forest and evergreen forest, mixed forest, shrub/scrub, grassland/herbaceous, pasture hay, and cultivated crops). The temperature of each pixel within each scene was calculated using the thermal band. In order to calculate the temperature an average emissivity value was used for each land cover type within each scene. The NLCD 2001 land cover classification raster data of the zones that cover Colorado were downloaded from USGS site and used to identify the land cover types within each scene. Areas that had temperature residual greater than 2?, and areas with temperature equal to 1? to 2?, were considered Landsat modeled very warm and warm surface exposures (thermal anomalies), respectively Spatial Domain: Extent: Top: 4546381.234113 m Left: 140556.857021 m Right: 573390.000000 m Bottom: 4094583.641581 m Contact Information: Contact Organization: Earth Science &Observation Center (ESOC), CIRES, University of Colorado at Boulder Contact Person: Khalid Hussein Address: CIRES, Ekeley Building Earth Science & Observation Center (ESOC) 216 UCB City: Boulder State: CO Postal Code: 80309-0216 Country: USA Contact Telephone: 303-492-6782 Spatial Reference Information: Coordinate System: Universal Transverse Mercator (UTM) WGS1984 Zone 13N False Easting: 500000.00000000 False Northing: 0.00000000 Central Meridian: -105.00000000 Scale Factor: 0.99960000 Latitude of Origin: 0.00000000 Linear Unit: Meter Datum: World Geodetic System 1984 (WGS 1984) Prime Meridian: Greenwich Angular Unit: Degree Digital Form: Format Name: Shape file

    Ignition of propane has been studied in a shock tube and by computational modeling to determine the effect of methyl tert-butyl ether (MTBE) as a fuel additive. MTBE and isobutene were added in amounts up to 25% of the fuel to propane-oxygen-argon mixtures in shock-tube experiments covering a range of temperatures between 1450 and 1800 K. Ignition delays were measured from chemiluminescence at 432 nm due to excited CH radicals. The temperature dependence of the ignition rates was analyzed to yield Arrhenius parameters of E{sub a}{approximately}40 kcal/mol and log (A){approximately} 9.0 sec{sup {minus}1} for the overall reaction. Reactions involving MTBE and its decomposition products were combined with an established propane mechanism in a numerical model to describe the kinetic interaction of this additive with a typical hydrocarbon fuel. The experiments and the kinetic model both show that MTBE and isobutene retard propane ignition with nearly equal efficiency. The kinetic model demonstrates that isobutene kinetics are responsible for inhibition by both MTBE and isobutene, and the specific elementary reactions which produce this behavior are identified.

    Methyl tert-butyl ether (MTBE) has received high attention as it contributed to cleaner air and contaminated thousands of underground storage tank sites. Because MTBE is very water soluble, it is more difficult to remove from water by conventional remediation techniques. Therefore, biodegradation of MTBE has become a remediation alternative. In order to understand the transport and transformation processes, they present a closed form solution as a screening tool in this paper. The possible reaction pathways of first-order reactions are described as a reaction matrix. The singular value decomposition is conducted analytically to decouple the partial differential equations of the multi-species transport system coupled by the reaction matrix into multiple independent subsystems. Therefore, the complexity of mathematical description for the reactive transport system is significantly reduced and analytical solutions may be previously available or easily derived.

    Ethanol (EtOH) and tert-Butyl methyl ether (MTBE) are both finding increased use as oxygenated additives to fuels. However, the environmental fate in the troposphere of these species is unclear when they escape as fugitive emissions. In several locations there are reports of human illness in response to MTBE in particular. Volatile organic compounds (VOC`s) such as these are generally thought to react by a variety of homogeneous free-radical mechanisms, usually beginning with attack by OH radical. However, we show by laboratory kinetic studies that the heterogeneous photoreaction on solid suspended metal-oxide particulates such as fly ash proceeds with a comparable rate, especially in urban environments. EtOH reacts to form acetaldehyde, and EtOH forms isobutene, methanol, and formaldehyde. Our work appears to be the first-ever demonstration that VOC`s can react as fast by a heterogeneous mechanism as by a homogeneous one in the atmosphere. Experiments by various optical and kinetic techniques show that the active phases in fly ash are Fe oxides, which are fairly abundant in other atmospheric particulates as well.

    A shallow Coastal Plain aquifer in rural Sampson Country, North Carolina, has been contaminated with petroleum hydrocarbon from a leaking underground storage tank containing gasoline.An extensive field characterization has been performed to define the horizontal and vertical distribution of soluble gasoline components and indicator parameters. A plume of dissolved methyl tert-butyl ether (MTBE) and the aromatic hydrocarbons benzene, toluene, ethylbenzene, and xylene isomers (BTEX) is present in the aquifer and has migrated over 600 ft from the source area. Background dissolved oxygen concentrations range from 7 to 8 mg/L, and nitrate concentrations range from 5 to 22 mg/L as N due to extensive fertilization of fields surrounding the spill. In the center of the BTEX plume, oxygen concentrations decline to less than 1 mg/L while nitrate concentrations remain high. The total mass flux of MTBE and all BTEX components decline with distance downgradient relative to a conservative tracer (chloride). At the source, the total BTEX concentration exceeds 75 mg/L while 130 ft downgradient, total BTEX concentrations are less than 4.9 mg/L, a 15-fold reduction. Toluene and ethylbenzene decline most rapidly followed by m-p-xylene, o-xylene and finally benzene. Biodegradation of TEX appears to be enhanced by the excess nitrate present in the aquifer while benzene biodegradation appears to be due to strictly aerobic processes.

    In this study we present a sampling and analytical methodology that can be used to assess consumers` exposures to methyl tertiary butyl ether (MTBE) that may result from routine vehicle refueling operations. The method is based on the collection of alveolar breath samples using evacuated one-liter stainless steel canisters and analysis using a gas chromatograph-mass spectrometer equipped with a patented `valveless` cryogenic preconcentrator. To demonstrate the utility of this approach, a series of breath samples was collected from two individuals (the person pumping the fuel and a nearby observer) immediately before and for 64 min after a vehicle was refueled with premium grade gasoline. Results demonstrate low levels of MTBE in both subjects` breaths before refueling, and levels that increased by a factor of 35 to 100 after the exposure. Breath elimination models fitted to the post exposure measurements indicate that the half-life of MTBE in the first physiological compartment was between 1.3 and 2.9 min. Analysis of the resulting models suggests that breath elimination of MTBE during the 64 min monitoring period was approximately 155 {mu}g for the refueling subject while it was only 30 {mu}g for the nearby observer. This analysis also shows that the post exposure breath elimination of other gasoline constituents was consistent with previously published observations. 20 refs., 3 figs., 4 tabs.

    The aim of this work was to study the reaction of ozone and combined ozone/hydrogen peroxide on oxygenated additives such as methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE) in dilute aqueous solution using controlled experimental conditions. Experiments conducted in a semi-continuous reactor with MTBE and ETBE in combination (initial concentration: 2 mmol/L of each) showed that ETBE was better eliminated than MTBE with both ozone and combined O[sub 3]/H[sub 2]O[sub 2]. batch experiments led to the determination of the ratio of the kinetic constants for the reaction of OH[degree]-radical with MTBE and ETBE (k[sub OH[degree]/ETBE]/k[sub OH[degree]//MTBE] = 1.7). Tert-butyl formate and tert-butyl acetate were identified as the ozonation byproducts of MTBE an ETBE, respectively, while tert-butyl alcohol was found to be produced during the ozonation of both compounds. 10 refs., 10 figs., 1 tab.

    Measurements have been made on the chemical and physical properties of two oil shales designated as interim reference oil shales by the Department of Energy. One oil shale is a Green River Formation, Parachute Creek Member, Mahogany Zone Colorado oil shale from the Anvil Points mine and the other is a Clegg Creek Member, New Albany shale from Kentucky. Material balance Fischer assays, kerogen concentrates, carbon aromaticities, thermal properties, and bulk mineralogic properties have been determined for the oil shales. The measured properties of the interim reference shales are comparable to results obtained from previous studies on similar shales. The western interim reference shale has a low carbon aromaticity, high Fischer assay conversion to oil, and a dominant carbonate mineralogy. The eastern interim reference shale has a high carbon aromaticity, low Fischer assay conversion to oil, and a dominant silicate mineralogy. Chemical and physical properties, including ASTM distillations, have been determined for shale oils produced from the interim reference shales. The distillation data were used in conjunction with API correlations to calculate a large number of shale oil properties that are required for computer models such as ASPEN. The experimental determination of many of the shale oil properties was beyond the scope of this study. Therefore, direct comparison between calculated and measured values of many properties could not be made. However, molecular weights of the shale oils were measured. In this case, there was poor agreement between measured molecular weights and those calculated from API and other published correlations. 23 refs., 12 figs., 15 tabs.

    Experimental and occupational exposure to Methyl Tert-Butyl Ether (MTBE) has been reported to induce neurotoxicological and neurobehavioral effects, such as headache, nausea, dizziness, and disorientation, etc. However, the molecular mechanisms involved in MTBE-induced neurotoxicity are still not well understood. In the present study, we investigated the effects of MTBE on spatial memory and the expression and function of GABA{sub A} receptor in the hippocampus. Our results demonstrated that intraventricular injection of MTBE impaired the performance of the rats in a Morris water maze task, and significantly increased the expression of GABA{sub A} receptor {alpha}1 subunit in the hippocampus. The phosphorylation of ERK1/2 decreased after the MTBE injection. Furthermore, the decreased ability of learning and the reduction of phosphorylated ERK1/2 level of the MTBE-treated rats was partly reversed by bicuculline injected 30 min before the training. These results suggested that MTBE exposure could result in impaired spatial memory. GABA{sub A} receptor may play an important role in the MTBE-induced impairment of learning and memory by regulating the phosphorylation of ERK in the hippocampus.

    The Colorado economic impact study summarizes employment and economic benefits to the state from activities associated with the Uranium Mill Tailings Remedial Action (UMTRA) Project during Colorado state fiscal year (FY) 1993. To capture employment benefits, a questionnaire was distributed to subcontractor employees at the active UMTRA Project sites of Grand Junction, Rifle, and Gunnison, Colorado. An estimated 52 percent of the employees working on the UMTRA Project responded to this information request. Economic data were requested from each prime subcontractor, as well as from the Remedial Action Contractor. The most significant benefits associated with the UMTRA Project in Colorado are: Direct employment was estimated at 894 workers; An estimated 89 percent of all direct employment was local; Secondary employment resulting from remedial action at the active Colorado UMTRA Project sites and the Grand Junction vicinity property program is estimated at 546 workers. Total employment (direct and secondary) is estimated at 1440 workers for the period of study (July 1, 1992, to June 30, 1993). An estimated $24.1 million was paid in wages to UMTRA workers in Colorado during FY1993; Direct and secondary wage earnings were estimated at $39.9 million; Income tax payments to the state of Colorado were estimated at $843,400 during FY1993; The gross economic impact of UMTRA Project activities in the state of Colorado is estimated at $70 million during the 1-year study period; and the net economic benefit to the state of Colorado was estimated at $57.5 million, or $5.90 per dollar of funding provided by Colorado. This figure includes both direct and secondary benefits but does not include the impact of alternative uses of the state funding.

    Energy Smart Colorado is an energy efficiency program established in 2011 in the central mountain region of Colorado. The program was funded through a grant of $4.9 million, awarded in August 2010 by the U.S. Department of Energys Better Buildings Program. As primary grant recipient, Eagle County coordinated program activities, managed the budget, and reported results. Eagle County staff worked closely with local community education and outreach partner Eagle Valley Alliance for Sustainability (now Walking Mountains Science Center) to engage residents in the program. Sub-recipients Pitkin County and Gunnison County assigned local implementation of the program in their regions to their respective community efficiency organizations, Community Office for Resource Efficiency (CORE) in Pitkin County, and Office for Resource Efficiency (ORE) in Gunnison County. Utility partners contributed $166,600 to support Home Energy Assessments for their customers. Program staff opened Energy Resource Centers, engaged a network of qualified contractors, developed a work-flow, an enrollment website, a loan program, and a data management system to track results.

    The benchmark goal that drives the report is to achieve a 20 percent reduction in carbon dioxide (CO{sub 2}) emissions in Colorado's electricity sector below 2005 levels by 2020. We refer to this as the '20 x 20 goal.' In discussing how to meet this goal, the report concentrates particularly on the role of utility-scale renewable energy and high-voltage transmission. An underlying recognition is that any proposed actions must not interfere with electric system reliability and should minimize financial impacts on customers and utilities. The report also describes the goals of Colorado's New Energy Economy5 - identified here, in summary, as the integration of energy, environment, and economic policies that leads to an increased quality of life in Colorado. We recognize that a wide array of options are under constant consideration by professionals in the electric industry, and the regulatory community. Many options are under discussion on this topic, and the costs and benefits of the options are inherently difficult to quantify. Accordingly, this report should not be viewed as a blueprint with specific recommendations for the timing, siting, and sizing of generating plants and high-voltage transmission lines. We convened the project with the goal of supplying information inputs for consideration by the state's electric utilities, legislators, regulators, and others as we work creatively to shape our electricity sector in a carbon-constrained world. The report addresses various issues that were raised in the Connecting Colorado's Renewable Resources to the Markets report, also known as the SB07-91 Report. That report was produced by the Senate Bill 2007-91 Renewable Resource Generation Development Areas Task Force and presented to the Colorado General Assembly in 2007. The SB07-91 Report provided the Governor, the General Assembly, and the people of Colorado with an assessment of the capability of Colorado's utility-scale renewable resources to contribute electric power in the state from 10 Colorado generation development areas (GDAs) that have the capacity for more than 96,000 megawatts (MW) of wind generation and 26,000 MW of solar generation. The SB07-91 Report recognized that only a small fraction of these large capacity opportunities are destined to be developed. As a rough comparison, 13,964 MW of installed nameplate capacity was available in Colorado in 2008. The legislature did not direct the SB07-91 task force to examine several issues that are addressed in the REDI report. These issues include topics such as transmission, regulation, wildlife, land use, permitting, electricity demand, and the roles that different combinations of supply-side resources, demand-side resources, and transmission can play to meet a CO{sub 2} emissions reduction goal. This report, which expands upon research from a wide array of sources, serves as a sequel to the SB07-91 Report. Reports and research on renewable energy and transmission abound. This report builds on the work of many, including professionals who have dedicated their careers to these topics. A bibliography of information resources is provided, along with many citations to the work of others. The REDI Project was designed to present baseline information regarding the current status of Colorado's generation and transmission infrastructure. The report discusses proposals to expand the infrastructure, and identifies opportunities to make further improvements in the state's regulatory and policy environment. The report offers a variety of options for consideration as Colorado seeks pathways to meet the 20 x 20 goal. The primary goal of the report is to foster broader discussion regarding how the 20 x 20 goal interacts with electric resource portfolio choices, particularly the expansion of utility-scale renewable energy and the high-voltage transmission infrastructure. The report also is intended to serve as a resource when identifying opportunities stemming from the American Recovery and Reinvestment Act of 2009.

    We consider the process of changing reference frames in the case where the reference frames are quantum systems. We find that, as part of this process, decoherence is necessarily induced on any quantum system described relative to these frames. We explore this process with examples involving reference frames for phase and orientation. Quantifying the effect of changing quantum reference frames serves as a first step in developing a relativity principle for theories in which all objects including reference frames are necessarily quantum.

    Citation Information: Originator: Geothermal Development Associates, Reno, Nevada Publication Date: 2012 Title: Colorado 2m Survey Edition: First Publication Information: Publication Place: Reno Nevada Publisher: Geothermal Development Associates, Reno, Nevada Description: Shallow temperature surveys are useful in early-stage geothermal exploration to delineate surface outflow zones, with the intent to identify the source of upwelling, usually a fault. Detailed descriptions of the 2-meter survey method and equipment design can be found in Coolbaugh et al. (2007) and Sladek et al. (2007), and are summarized here. The survey method was devised to measure temperature as far below the zone of solar influence as possible, have minimal equilibration time, and yet be portable enough to fit on the back of an all-terrain vehicle (ATV); Figure 2). This method utilizes a direct push technology (DPT) technique where 2.3 m long, 0.54 outer diameter hollow steel rods are pounded into the ground using a demolition hammer. Resistance temperature devices (RTD) are then inserted into the rods at 2-meter depths, and allowed to equilibrate for one hour. The temperatures are then measured and recorded, the rods pulled out of the ground, and re-used at future sites. Usually multiple rods are planted over the course of an hour, and then the sampler returns back to the first station, measures the temperatures, pulls the rods, and so on, to eliminate waiting time. At Wagon Wheel Gap, 32 rods were planted around the hot springs between June 20 and July 1, 2012. The purpose was to determine the direction of a possible upflow fault or other structure. Temperatures at 1.5m and 2m depths were measured and recorded in the attribute table of this point shapefile. Several anomalous temperatures suggest that outflow is coming from a ~N60W striking fault or shear zone that contains the quartz-fluorite-barite veins of the adjacent patented mining claims. It should be noted that temperatures at 2m depth vary according to the amount of solar heating from above, as well as possible geothermal heating from below.

    To protect human health and the environment, the Uranium Mill Tailings Remedial Action (UMTRA) Project will remediate the uranium mill tailings site at Gunnison Colorado. There are explicit requirements (i.e., 40 CFR Part 192) for the surface remediation of radiologically contaminated soils on UMTRA sites. The removal of subpile sediment to the depth required by 40 CFR Part 192 will leave in place deeper foundation sediment that is contaminated with hazardous constituents other than radium-226 and thorium-230. The Department of Energy and the Colorado Department of Health have questioned whether this contaminated soil could potentially act as a continuing source of ground water contamination even after surface remediation based on 40 CFR Part 192 is complete. To evaluate the subpile sediments as a potential source of ground water contamination, the Gunnison Subpile study was initiated. This report summarizes the results and findings of this study.

    DOE Patents [OSTI]

    Kronberg, J.W.

    1994-05-31T23:59:59.000Z

    A high frequency reference electrode for electrochemical experiments comprises a mercury-calomel or silver-silver chloride reference electrode with a layer of platinum around it and a layer of a chemically and electrically resistant material such as TEFLON around the platinum covering all but a small ring or halo' at the tip of the reference electrode, adjacent to the active portion of the reference electrode. The voltage output of the platinum layer, which serves as a redox electrode, and that of the reference electrode are coupled by a capacitor or a set of capacitors and the coupled output transmitted to a standard laboratory potentiostat. The platinum may be applied by thermal decomposition to the surface of the reference electrode. The electrode provides superior high-frequency response over conventional electrodes. 4 figs.

    An optical voltage reference for providing an alternative to a battery source is described. The optical reference apparatus provides a temperature stable, high precision, isolated voltage reference through the use of optical isolation techniques to eliminate current and impedance coupling errors. Pulse rate frequency modulation is employed to eliminate errors in the optical transmission link while phase-lock feedback is employed to stabilize the frequency to voltage transfer function. 2 figures.

    SciTech Connect (OSTI)

    Hurlbut, D. J.

    2009-12-01T23:59:59.000Z

    Colorado has more renewable energy potential than it is ever likely to need for its own in-state electricity consumption. Such abundance may suggest an opportunity for the state to sell renewable power elsewhere, but Colorado faces considerable competition from other western states that may have better resources and easier access to key markets on the West Coast. This report examines factors that will be important to the development of interstate commerce for electricity generated from renewable resources. It examines market fundamentals in a regional context, and then looks at the implications for Colorado.

    A precision displacement reference system is described, which enables real time accountability over the applied displacement feedback system to precision machine tools, positioning mechanisms, motion devices, and related operations. As independent measurements of tool location is taken by a displacement feedback system, a rotating reference disk compares feedback counts with performed motion. These measurements are compared to characterize and analyze real time mechanical and control performance during operation.

    The purpose of this environmental assessment (EA) is to provide the U.S. Department of Energy (DOE) and the public with information on potential environmental impacts associated with the development of the Ponnequin Wind Energy Project in Colorado. This EA and public comments received on it will be used in DOE`s deliberations on whether to release funding for the project. This document provides a detailed description of the proposed project and an assessment of potential impacts associated with its construction and operations. Resources and conditions considered in the analysis include streams; wetlands; floodplains; water quality; soils; vegetation; air quality; socioeconomic conditions; energy resources; noise; transportation; cultural resources; visual and land use resources; public health and safety; wildlife; threatened, endangered, and candidate species; and cumulative impacts. The analysis found that the project would have minimal impacts on these resources and conditions, and would not create impacts that exceed the significance criteria defined in this document. 90 refs., 5 figs.

    The Colorado economic impact study summarizes employment and economic benefits to the state from activities associated with the Uranium Mill Tailings Remedial Action (UMTRA) Project during Colorado state fiscal year 1994 (1 July 1993 through 30 June 1994). To capture employment information, a questionnaire was distributed to subcontractor employees at the active UMTRA Project sites of Grand Junction, Naturita, Gunnison, and Rifle, Colorado. Economic data were requested from each site prime subcontractor, as well as from the Remedial Action Contractor. Information on wages, taxes, and subcontract expenditures in combination with estimates and economic multipliers is used to estimate the dollar economic benefits to Colorado during the state fiscal year. Finally, the fiscal year 1994 estimates are compared to fiscal year 1993 employment and economic information.

The temperature is calculated using the Emissivity Normalization Algorithm that separate temperature from emissivity. The incoming solar radiation was calculated using spatial based insolation model developed by Fu and Rich (1999). Then the temperature due to solar radiation was calculated using emissivity derived from ASTER data. The residual temperature, i.e. temperature due to solar radiation subtracted from ASTER temperature was used to identify thermally anomalous areas. Areas that had temperature greater than 2? were considered ASTER modeled very warm surface exposures (thermal anomalies) Spatial Domain: Extent: Top: 4217727.601630 m Left: 394390.400264 m Right: 460179.841813 m Bottom: 4156258.036086 m Contact Information: Contact Organization: Earth Science &Observation Center (ESOC), CIRES, University of Colorado at Boulder Contact Person: Khalid Hussein Address: CIRES, Ekeley Building Earth Science & Observation Center (ESOC) 216 UCB City: Boulder State: CO Postal Code: 80309-0216 Country: USA Contact Telephone: 303-492-6782 Spatial Reference Information: Coordinate System: Universal Transverse Mercator (UTM) WGS1984 Zone 13N False Easting: 500000.00000000 False Northing: 0.00000000 Central Meridian: -105.00000000 Scale Factor: 0.99960000 Latitude of Origin: 0.00000000 Linear Unit: Meter Datum: World Geodetic System 1984 (WGS 1984) Prime Meridian: Greenwich Angular Unit: Degree Digital Form: Format Name: Shape file

  15. Colorado Better Buildings Project Final Report

    2013-12-30T23:59:59.000Z

    The Colorado Better Buildings project intended to bring new and existing energy efficiency model programs to market with regional collaboration and funding partnerships. The goals for Boulder County and its program partners were to advance energy efficiency investments, stimulate economic growth in Colorado and advance the states energy independence. Collectively, three counties set out to complete 9,025 energy efficiency upgrades in 2.5 years and they succeeded in doing so. Energy efficiency upgrades have been completed in more than 11,000 homes and businesses in these communities. Boulder County and its partners received a $25 million BetterBuildings grant from the U.S. Department of Energy under the American Recovery and Reinvestment Act in the summer of 2010. This was also known as the Energy Efficiency and Conservation Block Grants program. With this funding, Boulder County, the City and County of Denver, and Garfield County set out to design programs for the residential and commercial sectors to overcome key barriers in the energy upgrade process. Since January 2011, these communities have paired homeowners and business owners with an Energy Advisor an expert to help move from assessment to upgrade with minimal hassle. Pairing this step-by-step assistance with financing incentives has effectively addressed many key barriers, resulting in energy efficiency improvements and happy customers. An expert energy advisor guides the building owner through every step of the process, coordinating the energy assessment, interpreting results for a customized action plan, providing a list of contractors, and finding and applying for all available rebates and low-interest loans. In addition to the expert advising and financial incentives, the programs also included elements of social marketing, technical assistance, workforce development and contractor trainings, project monitoring and verification, and a cloud-based customer data system to coordinate among field advisors and across local governments and local service vendors. A portion of the BetterBuildings grant went to the Metro Mayors Caucus (MMC) who worked in partnership with the Denver Regional Council of Governments (DRCOG) to conduct a series of 10 energy efficiency workshops for local government officials and other interested parties. The workshops helped showcase lessons learned on energy efficiency and helped guide other local governments in the establishment of similar programs. The workshops covered a wide range of energy efficiency and renewable energy topics such as clean energy finance, social mobilization and communications, specific case studies of Colorado towns, energy efficiency codes, net zero buildings and solar power. Since the programs launched in January 2011, these communities have collectively spurred economic investments in energy efficiency, achieved greater than 5:1 leveraging of grant funds, saved energy and reduced greenhouse gas emissions, provided trainings for a robust local energy contractor network, and proved out viable and replicable program models that local utilities and other communities are adopting, with long lasting market transformation.

    Results of radiological surveys of two inactive uranium-mill sites near Rifle, Colorado, in May 1976 are presented. These sites are referred to as Old Rifle and New Rifle. The calculated /sup 226/Ra inventory of the latter site is much higher than at the older mill location. Data on above-ground measurements of gamma exposure rates, surface and near-surface concentration of /sup 226/Ra in soil and sediment samples, concentration of /sup 226/Ra in water, calculated subsurface distribution of /sup 226/Ra, and particulate radionuclide concentrations in air samples are given. The data serve to define the extent of contamination in the vicinity of the mill sites and their immediate surrounding areas with tailings particles. Results of these measurements were utilized as technical input for an engineering assessment of these two sites.

    This report is a summary of environmental information gathered during a review of the documents pertaining to Project Rulison and interviews with personnel who worked on the project. Project Rulison was part of Operation Plowshare (a program designed to explore peaceful uses for nuclear devices). The project consisted of detonating a 43-kiloton nuclear device on September 10, 1969, in western Colorado to stimulate natural gas production. Following the detonation, a reentry well was drilled and several gas production tests were conducted. The reentry well was shut-in after the last gas production test and was held in standby condition until the general cleanup was undertaken in 1972. A final cleanup was conducted after the emplacement and testing wells were plugged in 1976. However, some surface radiologic contamination resulted from decontamination of the drilling equipment and fallout from the gas flaring during drilling operations. With the exception of the drilling effluent pond, all surface contamination at the Rulison Site was removed during the cleanup operations. All mudpits and other excavations were backfilled, and both upper and lower drilling pads were leveled and dressed. This report provides information regarding known or suspected areas of contamination, previous cleanup activities, analytical results, a review of the regulatory status, the site`s physical environment, and future recommendations for Project Ruhson. Based on this research, several potential areas of contamination have been identified. These include the drilling effluent pond and mudpits used during drilling operations. In addition, contamination could migrate in the gas horizon.

    In an evaluation of the Department of Energy (DOE) Occupational Safety and Health programs for government-owned contractor-operated (GOCO) activities, the Department of Labor`s Occupational Safety and Health Administration (OSHA) recommended a technical information exchange program. The intent was to share written safety and health programs, plans, training manuals, and materials within the entire DOE community. The OSH Technical Reference (OTR) helps support the secretary`s response to the OSHA finding by providing a one-stop resource and referral for technical information that relates to safe operations and practice. It also serves as a technical information exchange tool to reference DOE-wide materials pertinent to specific safety topics and, with some modification, as a training aid. The OTR bridges the gap between general safety documents and very specific requirements documents. It is tailored to the DOE community and incorporates DOE field experience.

    This report, Coal Data: A Reference, summarizes basic information on the mining and use of coal, an important source of energy in the US. This report is written for a general audience. The goal is to cover basic material and strike a reasonable compromise between overly generalized statements and detailed analyses. The section ``Supplemental Figures and Tables`` contains statistics, graphs, maps, and other illustrations that show trends, patterns, geographic locations, and similar coal-related information. The section ``Coal Terminology and Related Information`` provides additional information about terms mentioned in the text and introduces some new terms. The last edition of Coal Data: A Reference was published in 1991. The present edition contains updated data as well as expanded reviews and additional information. Added to the text are discussions of coal quality, coal prices, unions, and strikes. The appendix has been expanded to provide statistics on a variety of additional topics, such as: trends in coal production and royalties from Federal and Indian coal leases, hours worked and earnings for coal mine employment, railroad coal shipments and revenues, waterborne coal traffic, coal export loading terminals, utility coal combustion byproducts, and trace elements in coal. The information in this report has been gleaned mainly from the sources in the bibliography. The reader interested in going beyond the scope of this report should consult these sources. The statistics are largely from reports published by the Energy Information Administration.
