Flexible Optical Chemical Sensor Platform for BTX  

Science Journals Connector (OSTI)

An in-plane flexible sensor platform for \\{BTXs\\} detection was developed using low-cost patterning techniques and foil-based optical components. The platform was produced by a combination of laser patterning, inkjet printing and capillary filling. Key optical components such as lightguides, optical cladding layers and metallic interconnections were realized on low cost substrates such as paper and PET. The sensing mechanism is based on the change in fluorescence spectra of a reporter dye, supported over a porous matrix. Detection limits down to 1 ppm for benzene, toluene and xylene have been measured. Response times down to a few seconds were observed for different gas concentrations.

Improved paving asphalt from Baku crudes  

SciTech Connect

An improved paving asphalt has been obtained from commercial BN-60/90 asphalt by adding certain components that are waste materials in petroleum refining: a still residue from the distillation of naphthenic acids to improve adhesion properties, asphalt obtained in deasphalting vacuum resid to improve ductility and impart freeze resistance, and a dialkylnaphthalene as a pour point depressant. Three different blend formulations were prepared by melting and mixing and analyzed for their physicochemical properties. The possibility was also investigated of expanding the raw material base for paving asphalts by including certain waste materials obtained in refining Baku crudes.

Detonation and deflagration characteristics of p-Xylene/gaseous hydrocarbon fuels/air mixtures  

Science Journals Connector (OSTI)

Abstract p-Xylene is an important intermediate for the production of polyethylene terephthalate, it has growing chemical industrial demand based on the statistics in the last few decades. In the process of producing p-Xylene, gaseous hydrocarbon fuels (e.g., H2, C1–C3) are usually involved, which renders p-Xylene highly possible mix with those gaseous hydrocarbon fuels as leaking occurs, this presents fire or explosion/detonation hazard at some specific conditions. To date, very limited data regarding its detonation and deflagration characteristics are available in previous literatures. In this study, experiments of measuring the overpressure and velocity of p-Xylene/gaseous hydrocarbon fuels (i.e., H2, C2H4, C3H8, CO)/air mixtures are carried out in a vertical detonation tube with an inner diameter of 200 mm and a length of 6.5 m to explore the detonation and deflagration characteristics of p-Xylene. The experimental results indicate that under the same initiation energy of 0.189 MJ m?2, pure p-Xylene/air and p-Xylene/CO/air cannot achieve detonation, only deflagrations are observed. However, under this same initiation energy, detonations occur in p-Xylene/H2/air, p-Xylene/C2H4/air and p-Xylene/C3H8/air mixtures. By comparing the combinatorial compositions of p-Xylene along with gaseous hydrocarbon fuels that within which detonation observed, the detonation sensitive of the mixtures in increasing order are obtained as following: p-Xylene/H2/air, p-Xylene/C3H8/air and p-Xylene/C2H4/air. The results also indicate the relative ease that p-Xylene/gaseous hydrocarbon fuel/air can be detonated mainly depends on the detonation sensitive of the gaseous fuel, which is supported by the critical energy of direct detonation initiation and chemical kinetic analysis.

Composition of paraffinic and naphthenic hydrocarbons in petroleum asphalts  

SciTech Connect

Uses a combination of chromatographic, chemical, and spectroscopic methods to determine the composition of the paraffinic and naphthenic hydrocarbons recovered from asphalts. Monitors the completeness of separation of the hydrocarbons from the aromatics on the basis of UV spectra. Finds that in the mixture of adduct-forming hydrocarbons, along with the n-paraffins there were admixtures of isoparaffins and longchain alkylnaphthenes. Concludes that a comparison of the structural-group composition of the asphalt fractions from the different crudes shows that there are only slight differences in the structure of the paraffinic/naphthenic hydrocarbons present in these asphalts, particularly with regard to those hydrocarbons that do not react with urea.

Application of Asphalt-aggregates Interfacial Energies to Evaluate Moisture-induced Damage of Warm Mix Asphalt  

Science Journals Connector (OSTI)

Abstract With increasing environmental awareness and high oil prices, use of warm mix asphalt (WMA) is gaining popularity in the asphalt industry. Different WMA technologies including use of additives to reduce the mixing and compaction temperatures are being applied. The present study uses the surface free energy (SFE) method as a mechanistic framework to evaluate the moisture susceptibility of warm mix asphalt (WMA) with Evotherm® WMA-additive. The SFE components of a modified PG64-22 asphalt binder with different percentages of Evotherm® and selected aggregates were measured in the laboratory. The work of adhesion, the work of debonding, and energy ratios were estimated to assess the moisture-induced damage potential of combinations of neat and Evotherm®-modified asphalt binders and different aggregates. The results indicated that use of Evotherm® resulted in increase in total SFE and work of adhesion and a reduction in the work of debonding, indicating a better possible aggregate-asphalt binder bond and lower moisture susceptibility potential. It is expected that the present study would be helpful in understanding the moisture-damage potential of flexible pavements constructed with WMA technologies.

Asphalt Roofing Shingles Into Energy Project Summary Report  

SciTech Connect

Based on a widely cited September, 1999 report by the Vermont Agency of Natural Resources, nearly 11 million tons of asphalt roofing shingle wastes are produced in the United States each year. Recent data suggests that the total is made up of about 9.4 million tons from roofing tear-offs and about 1.6 million tons from manufacturing scrap. Developing beneficial uses for these materials would conserve natural resources, promote protection of the environment and strengthen the economy. This project explored the feasibility of using chipped asphalt shingle materials in cement manufacturing kilns and circulating fluidized bed (CFB) boilers. A method of enhancing the value of chipped shingle materials for use as fuel by removing certain fractions for use as substitute raw materials for the manufacture of new shingles was also explored. Procedures were developed to prevent asbestos containing materials from being processed at the chipping facilities, and the frequency of the occurrence of asbestos in residential roofing tear-off materials was evaluated. The economic feasibility of each potential use was evaluated based on experience gained during the project and on a review of the well established use of shingle materials in hot mix asphalt. This project demonstrated that chipped asphalt shingle materials can be suitable for use as fuel in circulating fluidized boilers and cement kilns. More experience would be necessary to determine the full benefits that could be derived and to discover long term effects, but no technical barriers to full scale commercial use of chipped asphalt shingle materials in these applications were discovered. While the technical feasibility of various options was demonstrated, only the use of asphalt shingle materials in hot mix asphalt applications is currently viable economically.

Evaluation of plastic–rubber asphalt: Engineering property and environmental concern  

Science Journals Connector (OSTI)

Abstract Waste rubber and plastic are accumulating heavily in China and causing significant environmental issues. In this study, the rubber and one kind of plastic, polypropylene (PP), were powdered and mixed with base asphalt to form plastic–rubber asphalt (PRA). This study evaluated PRA and the mixture in two-folds, engineering properties and environmental concerns. SBS asphalt, one commonly used asphalt binder in China, was adopted as a control. To evaluate the environmental burdens of PRA mixture and SBS asphalt mixture, a cradle-to-gate life cycle assessment (LCA) modeling was performed. Throughout the study, it is revealed that: (1) as a binder, PRA is weaker in terms of softening point, elastic recovery and fatigue performance versus SBS asphalt, but the differences are limited; (2) PRA mixture are close to SBS asphalt mixture for the high temperature, low temperature performances and water durability; (3) PRA mixture is more environmental-friendly compared to SBS asphalt mixture.

Use of a warm mix asphalt additive to reduce the production temperatures and to improve the performance of asphalt rubber mixtures  

Science Journals Connector (OSTI)

Asphalt rubber mixtures are often described as environmentally friendly mixtures due to the incorporation of recycled rubber from used tires and due to their improved service life. In fact, their fatigue cracking and rut resistance properties are better than those of conventional asphalt concrete mixtures. However, asphalt rubber mixtures demand higher production temperatures than conventional mixtures due to the higher viscosity of the asphalt rubber binder. The objective of this paper is to assess the efficiency of using a surfactant based additive in the production of warm mix asphalts, by lowering the mixing temperatures of asphalt rubber and asphalt concrete mixtures without changing their performance. Several laboratory tests were carried out on asphalt rubber and asphalt concrete mixtures, with and without the additive, in order to evaluate and compare the performance of the mixtures. It was concluded that the incorporation of small amounts of a surfactant based additive allowed reducing the production temperatures of both types of mixture by 30 °C without compromising their performance, and this can be seen as a great step forward towards the production of cleaner asphalt rubber mixtures.

Asphalt emulsion sealing of uranium mill tailings. 1980 annual report  

SciTech Connect

Studies of asphalt emulsion sealants conducted by the Pacific Northwest Laboratory have demonstrated that the sealants are effective in containing radon and other potentially hazardous material within uranium tailings. The laboratory and field studies have further demonstrated that radon exhalation from uranium tailings piles can be reduced by greater than 99% to near background levels. Field tests at the tailings pile in Grand Junction, Colorado, confirmed that an 8-cm admix seal containing 22 wt% asphalt could be effectively applied with a cold-mix paver. Other techniques were successfully tested, including a soil stabilizer and a hot, rubberized asphalt seal that was applied with a distributor truck. After the seals were applied and compacted, overburden was applied over the seal to protect the seal from ultraviolet degradation.

Study of ice and snow melting process on conductive asphalt solar collector  

Science Journals Connector (OSTI)

This paper investigates the snow melting process on asphalt pavements as solar collector by experiments and numerical simulation. A numerical simulation method was used to predict the general design requirements for snow melting system of asphalt pavements, and a type of experimental asphalt snow melting system has been built using the design parameters obtained from the preceding simulation. Graphite powders were used to improve the thermal conductivity of asphalt concrete and thus resulting in an improved efficiency of asphalt collector. A laboratory snow melting test was performed after real snowstorm events. The effects of thermal conductive asphalt concrete (CAC) on snow melting performance and asphalt pavement temperature distribution were evaluated. The heat transfer in the asphalt slabs and the heat requirement for the snow melting were analyzed. The results that are obtained show that asphalt solar collector (ASC) provides us a better alternative method for snow melting. The higher fluid temperature is a positive way to improve the performance of snow melting system. However, it is unnecessary to keep a too high fluid temperature so as to reduce the waste of energy. The non-uniform temperatures in the asphalt slabs are noticeable. Furthermore, the heat-transmission and the snow melting performance can be enhanced using CAC.

Evaluation of western and eastern shale oil residua as asphalt pavement recycling agents  

SciTech Connect

The objective of this investigation was to perform a preliminary evaluation of the utility of residual materials prepared from Green River Formation (western) and New Albany Shale (eastern) shale oils as recycling agents for aged asphalt pavement. Four petroleum asphalts were first aged by a thin-film accelerated-aging test, which simulates long service life of asphalt in pavement. The aged asphalts were mixed (recycled) with Green River Formation shale oil distillation residua to restore the original viscosities. Separately, for comparison, a commercial recycling agent was used to recycle the aged asphalts under the same circumstances. The recycled asphalts were reaged and the properties of both binder and asphalt-aggregate mixtures studied. Originally, the same study was intended for an eastern shale residua. However, the eastern shale oil distillation residua with the required flash point specification also had the properties of a viscosity builder; therefore, it was studied as such with asphalts that do not achieve sufficient viscosity during processing to serve as usable binders. Results show that Green River Formation shale oil residuum can be used to restore the original asphalt properties with favorable rheological properties, the shale oil residuum has a beneficial effect on resistance to moisture damage, the low-temperature properties of the shale oil residuum recycled asphalts are not adversely affected, and the low-temperature properties of the shale oil residuum recycled asphalts are dependent upon the chemistry of the mixture. The eastern shale oil residua was blended with soft petroleum asphalts. Results show the products have higher viscosities than the starting materials, the rheological properties of the soft asphalt-eastern shale oil residue blends are acceptable, and the eastern shale oil residue has dispersant properties despite its high viscosity. 11 refs., 3 figs., 9 tabs.

Evaluation of moisture susceptibility of asphalt mixes containing RAP and different types of aggregates and asphalt binders using the surface free energy method  

Science Journals Connector (OSTI)

Abstract The surface free energy (SFE) measurement of asphalt binder and aggregate is considered a reliable mechanistic framework for evaluating the moisture-induced damage potential of asphalt mixes. In the present study, the SFE method was used to evaluate the effects of asphalt binder type, Reclaimed Asphalt Pavement (RAP) and its amount, and aggregate type on the moisture-induced damage potential of asphalt mixes. The SFE components (non-polar, acid and base) of a PG 64-22 and a PG 76-28 (polymer-modified) asphalt binders, blended with different amounts of RAP binder (0%, 10%, 25% and 40%) were measured in the laboratory using a Dynamic Contact Angle (DCA) analyzer. Also, the SFE components of six types of aggregates, namely limestone, rhyolite, sandstone, granite, gravel, and basalt were used in this study. The SFE components of limestone and rhyolite aggregates were measured using a Universal Sorption Device (USD), while those of the sandstone, granite, gravel, and basalt aggregates were obtained from the literature. The energy ratio parameters estimated based on the spreading coefficient, the work of adhesion, and the work of debonding were used to assess the moisture-induced damage potential of different combinations of asphalt binders and different RAP binder contents and aggregates. The SFE test results indicated that the acid SFE component of PG 64-22 and PG 76-28 asphalt binders increase with the addition of RAP binder, while the base SFE component remains almost unchanged. Also, the wettability and the work of adhesion of both PG 64-22 and PG 76-28 asphalt binders over different types of aggregates increased with an increase in RAP content (by 25% and more). Based on the energy ratio parameters, it was found that the resistance to moisture-induced damage increased with an increase in RAP content for both PG 64-22 and PG 76-28 asphalt binders and all types of aggregates, specifically when higher RAP contents were used. Moreover, it was found that the higher the total SFE of the aggregates, the lower the energy ratio parameter values. Therefore, a high total SFE component of aggregate may result in a high moisture-induced damage potential of the mix. The results presented herein are expected to be helpful in mechanistically assessing the moisture-induced damage potential of asphalt mixes, produced with polymer-modified and non-polymer-modified asphalt binders, containing RAP.

Evaluation of an eastern shale oil residue as an asphalt additive  

SciTech Connect

An evaluation of eastern shale oil (ESO) residue as an asphalt additive to reduce oxidative age hardening and moisture susceptibility was conducted by Western Research Institute (WRI). The ESO residue, have a viscosity of 23.9 Pa{lg_bullet}s at 60{degree}C (140{degree}F), was blended with three different petroleum-derived asphalts, ASD-1, AAK-1, and AAM-1, which are known to be very susceptible to oxidative aging. Rheological and infrared analyses of the unaged and aged asphalts and the blends were then conducted to evaluate oxidative age hardening. In addition, the petroleum-derived asphalts and the blends were coated onto three different aggregates, Lithonia granite (RA), a low-absorption limestone (RD), and a siliceous Gulf Coast gravel (RL), and compacted into briquettes. Successive freeze-thaw cycling was then conducted to evaluate the moisture susceptibility of the prepared briquettes. The rheological analyses of the unaged petroleum-derived asphalts and their respective blends indicate that the samples satisfy the rutting requirement. However, the aging indexes for the rolling thin film oven (RTFO)-aged and RTFO/pressure aging vessel (PAV)-aged samples indicate that the blends are stiffer than the petroleum-derived asphalts. This means that when in service the blends will be more prone to pavement embrittlement and fatigue cracking than the petroleum-derived asphalts. Infrared analyses were also conducted on the three petroleum-derived asphalts and the blends before and after RTFO/PAV aging. In general, upon RTFO/PAV aging, the amounts of carbonyls and sulfoxides in the samples increase, indicating that the addition of the ESO residue does not mitigate the chemical aging (oxidation) of the petroleum-derived asphalts. This information correlates with the rheological data and the aging indexes that were calculated for the petroleum-derived asphalts and the blends.

Biofiltration of asphalt emissions: Full-scale operation treating off-gases from polymer-modified asphalt production  

SciTech Connect

In response to complaints from nearby residents, a biofilter was designed, installed, and tested for treating odors in one of three odorous emission streams from an asphalt plant producing polymer-modified asphalt. Hydrogen sulfide (H{sub 2}S) was determined to be the most prevalent gaseous reduced sulfur compound and was detected in the emission stream only when polymer material was being added to raw asphalt. Emission stream H{sub 2}S concentrations were quite variable, ranging from 16 to approximately 30,000 ppm (v/v) and considered the likely compound contributing most to the plant's odor complaints. The biofilter was effective in controlling odor from the production process and removed an overall average of 65% of the H{sub 2}S during polymer addition, and for H{sub 2}S concentrations less than 400 ppmv, removal averaged 98%. These removal efficiencies reflect data from the biofilter operating at 2.5-minute empty bed residence time in 1996 and a 6.1-minute empty bed residence time in 1997. The biofilter's bed became increasingly acidified during the plant's 1997 operating season producing a pH gradient through the bed ranging from a high of 6.6 to a low of 3.1. The bed medium moisture content remained constant at about 60% (wet weight basis), but changes were observed in the water potential: no correlation to performance was determined. Changes in the microbial community reflected the bed acidification trend, with acidophiles becoming generally more numerous in the bed's deeper portions and in the mid to late season when the bed was most acidified. Bed acidification did not impact the biofilter's H{sub 2}S removal efficiency.

Biofiltration of Asphalt Emissions: Full-scale Operation Treating Off-gases from Polymer-modified Asphalt Production  

SciTech Connect

In response to complaints from nearby residents, a biofilter was designed, installed, and tested for treating odors in one of three odorous emission streams from an asphalt plant producing polymer-modified asphalt. Hydrogen sulfide (H2S) was determined to be the most prevalent gaseous reduced sulfur compound and was detected in the emission stream only when polymer material was being added to raw asphalt. Emission stream H2S concentrations we requite variable, ranging from 16 to approximately 30,000 ppm (v/v) and considered the likely compound contributing most to the plant's odor complaints. The biofilter was effective in controlling odor from the production process and removed an overall average of 65% of the H2S during polymer addition, and for H2S concentrations less than 400 ppmv, re m oval averaged 98%. These removal efficiencies reflect data from the biofilter operating at 2.5-minute empty bed residence time in 1996 and a 6.1-minute empty bed residence time in 1997. The biofilter's bed became increasingly acidified during the plant's 1997 operating season producing a pH gradient through the bed ranging from a high of 6.6 to a low of 3.1. The bed medium moisture content remained constant at about 60% (wet weight basis), but changes were observed in the water potential: no correlation to performance was determined. Changes in the microbial community reflected the bed acidification trend, with acidophiles becoming gene rally more numerous in the bed's deeper portions and in the mid to late season when the bed was most acidified. Bed acidification did not impact the biofilter's H2S removal efficiency. Nearby residents we resurveyed and roughly half of the respondents indicated that the odor conditions had improved, one-third felt odor conditions were unchanged and the remaining 15% felt odor conditions were worse despite the fact that only one of three of the plant's odorous emission streams were treated by the biofilter. Plans are to implement biofiltration for odor control at all of the facility's emission points.

Rheological properties and chemical analysis of nanoclay and carbon microfiber modified asphalt with Fourier transform infrared spectroscopy  

Science Journals Connector (OSTI)

This work aims to improve the rutting and fatigue cracking resistance of asphalt binders using selected nano- or micro-sized materials and to shed light on the microstructure changes induced by such modification to asphalt binders. The four modifiers (Nanomer I.44P, carbon microfiber, non-modified nanoclay and polymer modified nanoclay) were added into the control asphalt binder (PG 58-34). The Superpave™ tests and Fourier transform infrared spectroscopy (FTIR) measurements were conducted for obtaining the complex shear modulus G* and microstructure distribution of modified asphalt binders. Meanwhile, the short-term and long-term aging processes of asphalt binders are simulated by rolling thin film oven (RTFO) and pressure aging vessel (PAV) tests. From the dynamic shear rheometer (DSR) and FTIR tests results, the complex shear modulus G* values of nano- or micro-materials (Nanomer I.44P, non-modified nanoclay and carbon microfiber) modified asphalt binders increase, and the performance of resistance to rutting is improved compared to the control asphalt binder. The addition of polymer modified nanoclay (PMN) into the control asphalt binder decreases the complex shear modulus, and enhances the resistance to fatigue cracking. Moreover, the addition of four modifiers into the control asphalt binder can delay and weaken the aging and oxidation effect.

State of the practice: Design and construction of asphalt paving materials with crumb-rubber modifier. Final report  

SciTech Connect

The document is a comprehensive overview of the terminology, processes, products, and applications of crumb rubber modifier (CRM) technology. The technology includes any use of scrap tire rubber in asphalt paving materials. In general, CRM technology can be divided into two categories--the wet process and the dry process. When CRM is incorporated into an asphalt paving material, it will modify the properties of the binder (asphalt rubber) and/or act as a rubber aggregate (rubber modified hot mix asphalt). The five concepts for using CRM discussed in the report are McDonald, PlusRide, generic dry, chunk rubber asphalt concrete, and continuous blending asphalt rubber. There are two principal unresolved engineering issues related to the use of CRM in asphalt paving materials. On the national level, the ability to recycle asphalt paving mixes containing CRM has not been demonstrated. At the State and local levels, these modified asphalt mixes must be field evaluated to establish expected levels of performance. The appendices provide guidelines for material specifications, mix design, and construction specifications. An experimental work plan for monitoring performance and a stack emission testing program are also included.

Evaluation of an eastern shale oil residue as an asphalt additive  

SciTech Connect

An evaluation of eastern shale oil (ESO) residue as an asphalt additive to reduce oxidative age-hardening and moisture susceptibility was conducted. The ESO residue, having a viscosity of 23.9 Pa{sm_bullet}s at 60{degrees}C (140{degrees}F), was blended with three different petroleum-derived asphalts, AAD-1, AAK-1, and AAM-1, that are known to be very susceptible to oxidative aging. Rheological and infrared analyses of the unaged and aged asphalts and the blends were then conducted to evaluate oxidative age-hardening. In addition, the petroleum-derived asphalts and the blends were coated onto three different aggregates, Lithonia granite (RA), a low-absorption limestone (RD), and a silicious Gulf Coast gravel (RL), and compacted into briquets. Successive freeze-thaw cycling was then conducted to evaluate the moisture susceptibility of the prepared briquets. The abbreviations used above for the asphalts and the aggregates are part of the Strategic Highway Research Program nomenclature.

Acute toxicity of toluene, hexane, xylene, and benzene to the rotifers Brachionus calyciflorus and Brachionus plicatilis  

SciTech Connect

A large number of studies on the biological effects of oil pollution in the aquatic environment deal with the effects of whole crude or refined oils or their water-soluble fractions. However, low boiling, aromatic hydrocarbons, which are probably the most toxic constituents of oil, have until now not been examined in sufficient detail. Toluene, benzene and xylene, constitute a major component of various oils. They may be readily lost by weathering but are toxic in waters that are relatively stagnant and are chronically polluted. Korn et al. have stated that toluene is more toxic than many other hydrocarbons such as benzene, though the latter are more water-soluble. Report of the effects of exposure to organic solvents like hexane or toluene are still limited although organic solvents are a well-known group of neurointoxicants. Various benzene derivates continue to be used as chemical intermediates, solvents, pesticides, so on, in spite of incomplete knowledge of their chronic toxicity. The majority of toxicity studies about the effects of pollution on aquatic organisms under controlled conditions have used either fish or the cladoceran Daphnia magna and there are few studies reported using rotifers. The effects of herbicides on population variables of laboratory rotifer cultures have been investigated. Rotifers are one of the main sources of zooplankton production and they have an important ecological significance in the aquatic environment. The present work was designed to investigate the effect of short-term exposure to some petroleum derivates which might be expected to occur immediately under an oil-slick, on freshwater and brackish environment rotifers. 18 refs., 1 tab.

Development of asphalts and pavements using recycled tire rubber. Phase 1, Technical feasibility. Technical progress report, September 1, 1994--August 31, 1995  

SciTech Connect

About 285 million tires are discarded every year; less than 100 million are currently being recycled, with the rest being placed in landfills and other waste sites. A solution to reduce the littering of the environment is to use ground tire rubber in road construction. Currently, about 27 million tons of asphalt are used each year in road construction and maintenance of the country`s 2 million miles of roads. If all of the waste tire rubber could be combined with asphalt in road construction, it would displace less than 6% of the total asphalt used each year, yet could save about 60 trillion Btus annually. Purpose of this project is to provide data needed to optimize the performance of rubber-asphalt concretes. The first phase is to develop asphalts and recycling agents tailored for compatibility with ground tire rubber. Chapter 2 presents results on Laboratory Testing and Evaluation: fractionate asphalt material, reblending for aromatic asphalts, verifying optimal curing parameters, aging of blends, and measuring ductilities of asphalt-rubber binders. Chapter 3 focuses on Evaluating Mixture Characteristics (modified binders). Chapter 4 covers Adhesion Test Development (water susceptibility is also covered). The final chapter focuses on the Performance/Economic Update and Commercialization Plan.

Traditional and Dissipated Energy approaches to compare the 2PB and 4PB flexural methodologies on a Warm Mix Asphalt  

Science Journals Connector (OSTI)

Abstract Two and four point bending tests are among the most common methodologies adopted for the fatigue characterization of asphalt mixes. Constraints and volumes of material are the main differences between these two testing procedures. This work presents the fatigue results from a warm asphalt mixture obtained with an innovative two point bending (2PB) apparatus and a traditional four point bending (4PB) one. The Dissipated Energy approach, based on the energy balance theory, as well as the traditional approach were chosen for the analysis. Finally, the influence of specimen volume on fatigue was assessed performing tests on specimens of different thicknesses.

Mutual changes in bitumen and rubber related to the production of asphalt rubber binders  

Science Journals Connector (OSTI)

Asphalt rubber (AR) mixtures are currently a material with an increasing use in road pavements due to their improved performance and environmental benefit of recycling rubber from used tires. AR binders have been widely applied, but the bitumen and rubber interactions remain poorly understood. The aim of this work is to quantify and correlate the changes in bitumen and rubber during AR binders’ production, in order to characterize the interactions between the AR constituent materials, e.g. residual bitumen and recovered rubber. A good correlation between the rheological and physical changes in the properties of rubber, bitumen and AR binder was observed.

6 - Nanoclay-modified asphalt mixtures for eco-efficient construction  

Science Journals Connector (OSTI)

Abstract: Polymeric nanocomposites are among the most exciting and promising classes of materials discovered recently. A number of physical properties are successfully enhanced when a polymer is modified with small amount of nanoclay on condition that the clay is dispersed at nanoscopic level. In this research, comparative rheological tests on binders and mechanical tests on asphalt mixtures containing unmodified and nanoclay modified bitumen were carried out. Two types of nanoclay were used: Nanofill-15 and Cloisite-15A. Rheological tests on binder were penetration, softening point, ductility and aging effect. Mechanical tests on asphalt mixture were Marshall stability, indirect tensile strength, resilient modulus, diametric fatigue and dynamic creep tests. Test results show that nanoclay can improve properties such as stability, resilient modulus and indirect tensile strength and result in superior performance compared to that of unmodified bitumen under dynamic creep. Nanoclays do not seem to have beneficial effects on fatigue behaviour at low temperatures. Optimum binder content and void in total mixture (VTM) increase by adding nanoclay to bitumen.

Recycling of Flue Gas Desulfurization residues in gneiss based hot mix asphalt: Materials characterization and performances evaluation  

Science Journals Connector (OSTI)

Abstract On the one hand, huge amount of Flue Gas Desulfurization (FGD) residues, produced during scrubbing flue gas, is discarded as solid waste. Such solid waste would cause serious environmental problems. One the other hand, high quality aggregates, such as limestone and basalt, are running out due to the rapid development of highway construction. Ungraded aggregates such as gneiss are therefore considered in China to replace the high quality aggregates. The application of FGD residues as a filler in gneiss based asphalt mixture has benefits both in environmental and economic sides. The main objective of this research was to visualize the raw materials characterization and evaluate the effect of FGD residues on the performance of gneiss based asphalt mixture. X-ray diffraction (XRD), X-ray fluorescence (XRF), Scanning Electron Microscope (SEM), Differential Scanning Calorimetric & Thermal gravimetric (DSC–TG) were used to investigate the features of raw materials. The performance of gneiss based asphalt mixture including high-temperature deformation resistance, low-temperature crack resistance and moisture-induced damage resistance were evaluated. Dynamic creep test, three-point bending test, Retained Marshall Stability (RMS), Tensile Strength Ratio (TSR), Indirect Tensile (IDT) strength and Resilient Modulus (MR) test were conducted and analyzed. Dissipated Creep Strain Energy to fracture (DCSEf) ratio, fracture energy and model analysis were also used to evaluate moisture resistance, crack resistance and deformation resistance of asphalt mixture respectively. Research results indicate that FGD residues can partly improve the moisture resistance and crack resistance of gneiss asphalt mixture, while it might worse the high-temperature deformation resistance.

The importance of the use phase on the LCA of environmentally friendly solutions for asphalt road pavements  

Science Journals Connector (OSTI)

Abstract In order to assess sustainability of products and processes, different methodologies have been developed and used in the last years. In the road pavement construction area, most methodologies used for Life Cycle Assessment (LCA) are essentially focused in the construction phase. The present paper analyses the importance of the use phase of a road in the LCA of different paving alternatives, namely by evaluating energy consumption and gaseous emissions throughout the road pavement’s life. Therefore, a new LCA methodology for road pavements was developed, and the results of its application to a case study involving the construction of alternative pavement structures are discussed. The study intends to assess the influence of using more sustainable paving construction alternatives (asphalt recycling vs. conventional asphalt mixtures), and/or different surface course materials (which have a higher influence on the rolling resistance and, therefore, affect the performance during the use phase). The LCA results obtained for this case study showed that the reductions in energy consumption and gaseous emissions obtained during the use phase, for pavement alternatives with a lower rolling resistance surface course, are higher than the total amount of energy consumption and gas emissions produced during construction. It is therefore clear that some improvements in the characteristics of the surface course may have an effect over the road use phase that will rapidly balance the initial costs and gas emissions of those interventions. The LCA results obtained also showed that the sustainability of pavement construction may also be improved using recycled asphalt mixtures.

Vapor–liquid equilibrium for the binary systems tetrahydrothiophene + toluene and tetrahydrothiophene + o-xylene at 368.15 K and 383.15 K  

Science Journals Connector (OSTI)

Isothermal vapor–liquid equilibrium (VLE) for tetrahydrothiophene + toluene and tetrahydrothiophene + o-xylene at 368.15 K and 383.15 K was measured with a recirculation still. Liquid- and vapor-phase compositions were determined with gas chromatography. All systems exhibit a small positive deviation from Raoult's law and show nearly ideal behavior. All VLE measurements passed the point test used. The experimental results were correlated with the Wilson model and compared with COSMO-SAC predictive models. COSMO-SAC predictions show a slight negative deviation from Raoult's law for all systems measured. Raoult's law can be used to describe all systems studied. The activity coefficients at infinite dilution are presented.

Transport study of hafnium(IV) and zirconium(IV) ions mutual separation by using Tri-n-butyl phosphate-xylene-based supported liquid membranes  

SciTech Connect

A Hf transport study through supported liquid membranes has been carried out to determine flux and permeability data for this metal ion. Tri-n-butyl phosphate (TBP)-xylene-based liquid membranes supported in polypropylene hydrophobic microporous film have been used. These data for hafnium and the previous data for zirconium have furnished the Zr to Hf flux ratio (S) as a function of nitric acid and TBP concentrations of the order of 12 in a single stage at room temperature. Optimum conditions for the separation of these two metal ions appear to 5-6 TBP mol/dm{sup 3} HNO{sub 3}, concentrations {le} 2.93 mol/dm{sup 3}, and 10C. The value of S from an aqueous solution containing 2.4% Hf with respect to Zr has been found to be >125 at 10C and 1.78 mol/dm{sup 3} TBP concentration in the membrane. The technique appears to be feasible for purification of Zr respect to Hf or vice versa.

SOLAR HEATING OF TANK BOTTOMS Application of Solar Heating to Asphaltic and Parrafinic Oils Reducing Fuel Costs and Greenhouse Gases Due to Use of Natural Gas and Propane  

SciTech Connect

The sale of crude oil requires that the crude meet product specifications for BS&W, temperature, pour point and API gravity. The physical characteristics of the crude such as pour point and viscosity effect the efficient loading, transport, and unloading of the crude oil. In many cases, the crude oil has either a very high paraffin content or asphalt content which will require either hot oiling or the addition of diluents to the crude oil to reduce the viscosity and the pour point of the oil allowing the crude oil to be readily loaded on to the transport. Marginal wells are significantly impacted by the cost of preheating the oil to an appropriate temperature to allow for ease of transport. Highly paraffinic and asphaltic oils exist throughout the D-J basin and generally require pretreatment during cold months prior to sales. The current study addresses the use of solar energy to heat tank bottoms and improves the overall efficiency and operational reliability of stripper wells.

Experimental investigation of regulated and unregulated emissions from a diesel engine fueled with ultralow-sulfur diesel fuel blended with ethanol and dodecanol  

Science Journals Connector (OSTI)

Experiments were conducted on a four-cylinder direct-injection diesel engine using ultralow-sulfur diesel as the main fuel, ethanol as the oxygenate additive and dodecanol as the solvent, to investigate the regulated and unregulated emissions of the engine under five engine loads at an engine speed of 1800 rev min?1. Blended fuels containing 6.1%, 12.2%, 18.2% and 24.2% by volume of ethanol, corresponding to 2%, 4%, 6% and 8% by mass of oxygen in the blended fuel, were used. The results indicate that with an increase in ethanol in the fuel, the brake specific fuel consumption becomes higher while there is little change in the brake thermal efficiency. Regarding the regulated emissions, HC and CO increase significantly at low engine load but might decrease at high engine load, \\{NOx\\} emission slightly decreases at low engine load but slightly increases at high engine load, while particulate mass decreases significantly at high engine load. For the unregulated gaseous emissions, unburned ethanol and acetaldehyde increase but formaldehyde, ethene, ethyne, 1,3-butadiene and BTX (benzene, toluene and xylene) in general decrease, especially at high engine load. A diesel oxidation catalyst (DOC) is found to reduce significantly most of the pollutants, including the air toxics.

Evaluation of a biomass derived oil for use as additive in paving asphalt  

SciTech Connect

Treatment and disposal costs of sewage sludge can represent up to 50% of a municipality`s annual wastewater treatment budget. Sewage sludge (30% solids) accounts 5% of Canadian landfill by weight, and the ever increasing volume of sludge coupled with the decreasing options available for disposal creates a growing problem for major municipalities. Current disposal options are agricultural application, incineration and landfill. Concern about heavy metal migration and public pressure to find a local solution has severely curtailed the spreading of sludge on agricultural land. Incineration is the major option for larger centers but the relatively high cost for incineration, ranging from $350 to $1000/t dry sludge, has caused a great deal of interest in methods of improving the cost effectiveness of incineration or in new equivalent technologies. The high cost and more stringent environmental regulations for incinerating municipal sludges have led to developing more efficient sludge management technologies that are not agricultural based. This paper describes applications of oils from sludge processing.

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

SciTech Connect

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

An NMR (nuclear magnetic resonance) investigation of the chemical association and molecular dynamics in asphalt ridge tar sand ore and bitumen  

SciTech Connect

Preliminary studies on tar sand bitumen given in this report have shown that the reassociation of tar sand bitumen to its original molecular configuration after thermal stressing is a first-order process requiring nearly a week to establish equilibrium. Studies were also conducted on the dissolution of tar sand bitumen in solvents of varying polarity. At a high-weight fraction of solute to solvent the apparent molecular weight of the bitumen molecules was greater than that of the original bitumen when dissolved in chloroform-d/sub 1/ and benzene-d/sub 6/. This increase in the apparent molecular weight may be due to micellar formation or a weak solute-solvent molecular complex. Upon further dilution with any of the solvents studied, the apparent molecular weight of the tar sand bitumen decreased because of reduced van der Waals forces of interaction and/or hydrogen bonding. To define the exact nature of the interactions, it will be necessary to have viscosity measurements of the solutions. 30 refs., 3 figs., 3 tabs.

Solvated Electron Technology{sup TM}. Non-Thermal Alternative to Waste Incineration  

SciTech Connect

Solvated Electron Technology (SET{sup TM}) is a patented non-thermal alternative to incineration for treating Toxic Substances Control Act (TSCA) and other mixed waste by destroying organic hazardous components. SET{sup TM} is a treatment process that destroys the hazardous components in mixed waste by chemical reduction. The residual material meets land disposal restriction (LDR) and TSCA requirements for disposal. In application, contaminated materials are placed into a treatment cell and mixed with the solvated electron solution. In the case of PCBs or other halogenated contaminants, chemical reactions strip the halogen ions from the chain or aromatic ring producing sodium chloride and high molecular weight hydrocarbons. At the end of the reaction, ammonia within the treatment cell is removed and recycled. The reaction products (such as sodium salts) produced in the process remain with the matrix. The SET{sup TM} process is 99.999% effective in destroying: polychlorinated biphenyls (PCBs); trichloroethane (TCA) and trichloroethene (TCE); dioxins; polycyclic aromatic hydrocarbons (PAHs); benzene, toluene, xylene (BTX); pesticides; fungicides; herbicides; chlorofluorocarbons (CFCs); hydro-chlorofluorocarbons (HCFCs), explosives and chemical-warfare agents; and has successfully destroyed many of the wastes listed in 40 Code of Federal Regulations (CFR) 261. In September 2007, U.S. Environmental Protection Agency (EPA) issued a Research and Development permit for SET for chemical destruction of 'pure' Pyranol, which is 60% PCBs. These tests were completed in November 2007. SET{sup TM} is recognized by EPA as a non-thermal process equivalent to incineration and three SET{sup TM} systems have been permitted by EPA as commercial mobile PCB destruction units. This paper describes in detail the results of select bench-, pilot-, and commercial-scale treatment of hazardous and mixed wastes for EPA, Department of Energy (DOE), and the Department of Defense(DoD), and the applicability of SET{sup TM} to currently problematic waste streams that have very limited treatment alternatives. In summary: SET{sup TM} operates as a non-thermal destruction process under low pressure. The process occurs in a closed system producing no hazardous off-gases and no regulated by-products such as dioxins or furans or their precursors. Advantages of SET{sup TM} include: - Organic contaminants are destroyed, not just removed, diluted or concentrated. - Operates as a closed system - produces no regulated secondary wastes. - Holds an EPA permit for PCB destruction. - Operates at ambient temperatures (70 deg. F). - Portable and sets up quickly in less than 4000 square feet of space. - Scalable to accommodate any size waste stream. - Requires minimal amounts of power, water and infrastructure. - Applicable to heterogeneous waste streams in all phases. The SET{sup TM} process is 99.9999% effective in destroying organic constituents of RCRA and TSCA waste, explosives and chemical-warfare agents; and has successfully destroyed many of the wastes listed in 40 Code of Federal Regulations (CFR) 261. The residual material meets land disposal restriction (LDR) and TSCA requirements for disposal. In November 2007, Commodore completed a treatability study on Pyranol to determine the effectiveness of SET{sup TM} treatment on oil containing 600,000 PPM PCBs. Laboratory results proved destruction of PCBs to less than 1 PPM at low temperatures and pressures. SET{sup TM} is a proven, safe and cost-effective alternative to incineration for some of the most difficult waste treatment problems that exist today. (authors)

Investigation on the solidification of several pure cyclic and aromatic hydrocarbons at pressures to 300 MPa  

SciTech Connect

The effect of pressure on the solidification of several saturated cyclic hydrocarbons and three xylene isomers are experimentally determined with a variable-volume view cell at pressures to 300 MPa and temperatures starting at 293.15 K. Solid–liquid transitions are observed for cyclooctane, cis-1,2-dimethylcyclohexane, trans-1,4-dimethylcyclohexane, p-xylene, o-xylene, and 2-methylnaphthalene. However, methylcyclohexane, ethylcyclohexane, cis-1,4-dimethylcyclohexane, and m-xylene remained liquid over the same operating pressure and temperature ranges. The experimental solid–liquid transition data are well represented with two empirical equations, the Simon equation and a 2nd-order polynomial equation. Data obtained in this study agree with literature data within ±0.4% for 2-methylnaphthalene and ±0.2% for p-xylene.

Method for making thin polypropylene film  

DOE Patents (OSTI)

An economical method is provided for making uniform thickness polypropylene film as thin as 100 Angstroms. A solution of polypropylene dissolved in xylene is formed by mixing granular polypropylene and xylene together in a flask at an elevated temperature. A substrate, such as a glass plate or microscope slide is immersed in the solution. When the glass plate is withdrawn from the solution at a uniform rate, a thin polypropylene film forms on a flat surface area of the glass plate as the result of xylene evaporation. The actual thickness of the polypropylene film is functional of the polypropylene in xylene solution concentration, and the particular withdrawal rate of the glass plate from the solution. After formation, the thin polypropylene film is floated from the glass plate onto the surface of water, from which it is picked up with a wire hoop.

Fractionation of reformate: A new variant of gasoline production technology  

SciTech Connect

The Novo-Ufa Petroleum Refinery is the largest domestic producer of the unique high-octane unleaded automotive gasolines AI-93 and AI-95 and the aviation gasolines B-91/115 and B-92. The base component for these gasolines is obtained by catalytic reforming of wide-cut naphtha; this basic component is usually blended with certain other components that are expensive and in short supply: toluene, xylenes, and alkylate. For example, the unleaded gasoline AI-93 has been prepared by blending reformate, alkylate, and toluene in a 65:20:15 weight ratio; AI-95 gasoline by blending alkylate and xylenes in an 80:20 weight ratio; and B-91/115 gasoline by compounding a reformate obtained with light straight-run feed, plus alkylate and toluene, in a 55:35:10 weight ratio. Toluene and xylenes have been obtained by process schemes that include the following consecutive processes: redistillation of straight-run naphtha cuts to segregate the required narrow fraction; catalytic reforming (Platforming) of the narrow toluene-xylene straight-run fraction; azeotropic distillation of the reformate to recover toluene and xylenes. A new technology based on the use of reformate fractions is proposed.

Flash Pyrolysis of Biomass with Reactive and Non-Reactive Gases: Summary Report for Period July 1983 through September 1984  

SciTech Connect

The purpose of this program is to study the conversion of biomass to liquid and gaseous hydrocarbon fuels and chemical feedstocks by a flash or rapid pyrolysis technique. During this period of study pine wood was flash pyrolyzed in atmospheres of methane and helium at a pressure of 50 psi and at temperatures up to 1050 C. The 1-inch I.D. entrained downflow tubular reactor was used in these experiments. Product yields of methane, ethane, ethylene, BTX, carbon monoxide and carbon dioxide were determined as a function of temperature and gas to wood ratio. Of particular interest were the ethylene and BTX yields. These represented as much as 29.6% and 24.6% of the carbon contained in the feed wood respectively when flash pyrolyzing in methane (flash methanolysls) and 14.7% and 9.7% when pyrolyzing in helium. In the case of flash methanolysis of wood the yields of ethylene and benzene increased with increasing methane to wood feed ratios. In the case of flash pyrolysis in helium the yields of ethylene and BTX decreased with increasing helium gas to wood feed ratios. These results indicate a mechanism by which a free radical reactive species originating from the wood interacts with the methane pyrolyzing gas to produce an enhanced yield of ethylene and benzene. The flash methanolysis of lignin extract from wood produced lower yields of ethylene, indicating the yields mainly originate from the cellulosic fractions of the wood. Some work was also performed on substituting wood ash for sillca flour (Cab-O-Sil) to allow free flow of wood particles through the entrained flow reactor. Preliminary process design and analysis indicates an economically competitive process for the flash methanolysis of wood for the production of methanol, benzene and ethylene. Future plans include completing the studies on obtaining the process chemistry of the flash methanolysis of woods, to obtain a better understanding of the enhanced ethylene and benzene yield and to investigate other biomass forms.

We study the Korteweg-de Vries-type equation dt u=-dx(dx^2 u+f(u)-B(t,x)u), where B is a small and bounded, slowly varying function and f is a nonlinearity. Many variable coefficient KdV-type equations can be rescaled into this equation. We study the long time behaviour of solutions with initial conditions close to a stable, B=0 solitary wave. We prove that for long time intervals, such solutions have the form of the solitary wave, whose centre and scale evolve according to a certain dynamical law involving the function B(t,x), plus an H^1-small fluctuation.

A straight-run naphtha is fractionated at about 66/sup 0/C, which is just below the boiling point of methylcyclopentane. The 66/sup 0/C+ fraction is reformed, and at least a portion of the reformate combined with the 66/sup 0/C- fraction and reacted under aromatization conditions over a zsm-5-type catalyst to form a C5+ product rich in aromatics. The C5+ aromaticized product and the remaining reformate can be either sent for BTx recovery or used as a high-octane component of a gasoline blending pool.

Mathematical models of interconnections between composition and properties of oils in the Apsheron oil-and gas-bearing region of Azerbaijan  

SciTech Connect

This paper reports on the example of oils in the Apsheron oil- and gas-bearing region and Apsheron archipelago located in the western part of the Southern Caspian depression, of which the authors have developed mathematical models of a group hydrocarbon composition; interconnection between oil density and content of asphalt-resin materials, benzine, and ligroin; interconnections between oil density and viscosity and temperature; and interconnections between content of asphalt-resin properties and low-temperature fractions. The models obtained enable us to extrapolate factual data on composition and properties of oils beyond the limits of fixed depths of burial of oil-saturated reservoirs both to a zone of great depths and increased temperatures where hydrocarbons were in a gaseous or oil and gaseous state, and to a zone of near-surface conditions where oils acquire the consistency of asphalts.

Measurement and correlation of phase equilibria for (water + aromatic hydrocarbon) binary mixtures at T = (573 to 623) K using microfluidic mixing  

Science Journals Connector (OSTI)

(Vapour + liquid) and (liquid + liquid) equilibria for (water + p-xylene) and (water + decalin) mixtures at T = (573 to 623) K were measured by a flow type apparatus with microfluidic system. The liquid–liquid slug flows in the microfluidic system were used for mixing of water and hydrocarbon due to high mass transfer between two liquid phases. The formations of the liquid–liquid slugs for (water + p-xylene) system were studied by changing the flow rate. The results of the liquid–liquid slug formations at hydrocarbon and water rich compositions were used for the measurements for (vapour + liquid) and (liquid + liquid) equilibria, respectively. It was found that the phase equilibria using the apparatus with the microfluidic system can be measured in a short residential time (1.6 to 3.2) min. The experimental results of the phase equilibria for (water + p-xylene) and (water + decalin) systems give that the regions of the (vapour + liquid) and (liquid + liquid) equilibria for both mixtures reduce with the increasing temperature. The mixture of (water + decalin) at T = (583 to 623) K forms the two phase regions of the (vapour + liquid) and (liquid + liquid) equilibria larger than those for (water + p-xylene) mixture. The experimental data of the phase equilibria obtained in this work were correlated with Peng–Robinson–Stryjek–Vera equation of state. The correlated results of the (liquid + liquid) equilibria for both systems represent the experimental data. For (vapour + liquid) equilibria, the results give the qualitative representations in the shape of the two phase region for both mixtures.

Studies of thin films and surfaces with optical harmonic generation and electron spectroscopy  

SciTech Connect

Optical second harmonic generation (SHG) and sum frequency generation (SFG) were used to study C{sup 60} thin solid films (low energy ED forbidden electronic excitations), and electron spectroscopy was used to study organic overlayers (xylenes) on Pt(111). Theory of SHG from a thin film is described in terms of surface and bulk contributions as well as local and nonlocal contributions to the optical nonlinearities. (1)In situ SHG data on C{sub 60} films during UHV film growth can be described in terms of only nonlocal contributions to both surface and bulk nonlinear susceptibilities. Microscopic origin of SHG response is discussed in terms of electric quadrupole and ED transitions of C{sub 60}. (2)Adsorption and thermal decomposition of ortho- and para-xylene on Pt(111) is studied using HREELS, LEED, AES, and thermal desorption spectroscopy. We have observed preferential decomposition of the methyl groups which leads to distinct decomposition pathways for ortho- and para-xylene on Pt(111).

In this study we created prototype solar-reflective nonwhite concrete tile and asphalt shingle roofing materials using a two-layer spray coating process intended to maximize both solar reflectance and factory-line throughput. Each layer is a thin, quick-drying, pigmented latex paint based on either acrylic or a poly(vinylidene fluoride)/acrylic blend. The first layer is a titanium dioxide rutile white basecoat that increases the solar reflectance of a gray-cement concrete tile from 0.18 to 0.79, and that of a shingle surfaced with bare granules from 0.06 to 0.62. The second layer is a "cool" color topcoat with weak near-infrared (NIR) absorption and/or strong NIR backscattering. Each layer dries within seconds, potentially allowing a factory line to pass first under the white spray, then under the color spray.

Assessment of the corrosivity of crude fractions from varying feedstock  

SciTech Connect

Crude corrosivity is becoming a critical issue because of frequent variation of feedstock based on spot market opportunities and high sulfur and naphthenic acid content of low cost crudes. The choice of remediation methods (blending, inhibition, upgrading, and/or process changes) depends on accurate prediction of the corrosivity of these crudes. This paper presents the results of autoclave and flow loop runs conducted to assess the corrosivity of Middle East, Shengli, and Bachequero-13 crudes fractions on several materials used in refinery construction. Autoclave tests were conducted in vacuum heater feed line (VHFL) and Asphalt`s fractions from each crude and in atmospheric gas oil (AGO) and heavy vacuum gas oil (HVGO) from the Bachequero-13. Flow loop tests were conducted only on the VHFL`s of each crude. As expected, the test results showed a major increase in corrosion rate with increasing temperature. Corrosion rates were generally less than 10 mpy for all materials at up to 300 C. At 400 C, corrosion rates on the low Cr steels (0 to 5 Cr) were generally around 100 mpy. For the Middle East and Shengli oils, the asphalt`s were more corrosive than the VHFL cuts. Only slight differences were found in the corrosivity of these two oils. By comparison, the Bachequero-13 fractions were generally more corrosive than those from the Shengli or the Middle Eastern crudes. At 200 ft/s (67 m/s), the corrosion rates of the carbon steel specimens were high in the Middle Eastern fraction compared to the Bachequero-13 and Shengli fractions.

Performance of Low Energy Crumb Rubber Modified Bituminous Mixes  

Science Journals Connector (OSTI)

Abstract Rising energy costs and increased awareness of emission problems in the production of Hot Mix Asphalt (HMA) have brought attention to the potential benefits of Warm Mix Asphalt (WMA) in India. Warm-mix asphalt is the generic term for a variety of technologies that allow the producers of hot-mix asphalt pavement material to lower the temperatures at which the material is mixed and placed on the road. Crumb Rubber Modified Bitumen (CRMB) is a popular binder in India. CRMB is composed of bitumen binder and tyre rubber. Tyre rubber, at various percentages, is added to the binder, addition of tyre rubber into binder results in a new product, which requires higher mixing temperatures compared to the conventional one, as well as increased mixing time, so as to get the uniformity of the product. A laboratory study was conducted at CSIR-Central Road Research Institute (CRRI) to investigate, how a commercially available chemical additive can be used to bring down the mixing and compaction temperature of CRMB mix as compared to the hot mix CRMB. Four different temperature ranges were considered in this study viz 1000C to 1050C, 1100C to 1150C, 1200C to 1250C and 1300C to 1350C to determine the various performance characteristics. The CRMB bituminous mix was prepared in these four temperature ranges and various mix tests were carried out to indicate to how the lower production and compaction temperatures affect the properties and performance characteristics of the mixes. After the laboratory evaluation it was found that CRMB Warm mix can be successfully produced at temperature as low as 110 °C and can be compacted at 80- 900C as compared to CRMB hot mix (155 °C). Full scale performance study indicate that process is highly energy efficient and environment friendly, warm mixes performed equivalent to “Hot Bituminous Mixes” and indicated encouraging results. After laboratory evaluation, a test track was successfully laid using low energy Crumb Rubber Modified Bitumen.

Thermodynamic analysis of organic Rankine cycle using dry working fluids  

SciTech Connect

Utilization of waste heat is not economically incentive to the industry once the temperature of the waste heat drops to a certain level. This is primarily due to a low efficiency when converting the energy of the waste heat to some forms of useful power. A Rankine cycle using organic fluids as working fluids, called organic Rankine cycle (ORC), is potentially feasible in recovering low-enthalpy containing heat sources. Nevertheless, an efficient operation of the ORC depends heavily on two factors: working conditions of the cycle and the thermodynamic properties of the working fluids. The main objective of this study is to investigate the effects of these two factors on the performance of the ORC. The working fluids under investigation are: benzene (C{sub 6}H), toluene (C{sub 7}H{sub 8}), p-xylene (C{sub 8}H{sub 10}), R113 and R123. Irreversibility of a system using various working fluids was studied since it represents the energy balance in recovering the waste heat. The study shows that the system efficiency increases as the inlet pressure of the turbine increases regardless of the working fluid used. Among the working fluids under investigation, p-xylene shows the highest efficiency while benzene the lowest. The study also shows that irreversibility depends on the type of heat source. Generally speaking, p-xylene has the lowest irreversibility in recovering a high temperature waste heat while R113 and R123 have a better performance in recovering a low temperature waste heat. In addition, an economic feasibility of ORC using various working fluids is given for ORC`s with commercial capacities.

The environmental aspects of the evaporation of BTEX from gasoline with and without ethanol  

Science Journals Connector (OSTI)

In this work the vapours from two columns simulating gasoline-contaminated soils (with and without ethanol) were monitored. Standards mixtures of BTEX, containing different ethanol contents were also analysed. The instrumental analysis was performed by Gas Chromatography with a Flame Ionisation Detector. Among BTEX, except benzene, in both columns the evaporation rate increases with time. In the gasoline/ethanol column this effect is higher particularly for the xylenes. Although the benzene concentrations were reduced in both columns, this reduction was less marked in the gasoline/ethanol column. The toluene concentrations were higher in the pure gasoline column.

SciTech Connect

Degradation rates of benzene, p-xylene, naphthalene, and o-dichlorobenzene have been determined in the Columbus, MS aquifer. The objective of this research was to measure the degradation of organic compounds in an aquifer, using pulse injection. Degradation rates of these compounds were calculated, and the rates were related to aquifer structure and hydrologic properties. the injection was made into the saturated zone of the unconfined aquifer. This technique is suggested for future field experiments because it distinguishes solute degradation from solute losses by sorption and evaporation and allows mass balance to be demonstrated throughout the course of the reaction in the aquifer. 18 refs., 6 figs., 3 tabs.

Uranium(VI) extraction by TBP in the presence of HDBP  

SciTech Connect

The influence of di-n-butyl phosphoric acid (HDBP) upon extraction of uranium(VI) by tri-n-butyl phosphate (TBP) from 0.5--3.0 M nitric acid solutions has been studied. It has been shown that the uranium(VI) distribution coefficient D{sub U} for extraction by 1.1 M TBP in tri-decane or xylene is increased when HDBP is present in the organic phase. For iso-molar solutions of (TBP + HDBP) with a total concentration of 0.36 M, and Uranium(VI) aqueous concentration up to 10--20 g/l, a maximum value of D{sub U} is observed when TBP/HDBP = 1; for higher U(VI) concentration the maximum gradually disappears, with D{sub U} growing monotonically with the HDBP content in the organic phase. Uranium(VI) absorption spectra for 1.1 M TBP in tri-decane or xylene, containing HDBP, provide evidence for the formation of compounds, of which composition is intermediate between uranyl nitrate--TBP disolvate and the U(VI)--HDBP complex. It is proposed that these intermediate compounds are UO{sub 2}(NO{sub 3}){sub 2}HDBP.TBP and UO{sub 2}(NO{sub 3}){sub 2}(HDBP){sub 2}.

Determination of specific activity of iron-55 by spectrophotometry and liquid scintillation counting with bathophenanthroline complex  

SciTech Connect

A method for determining the macroscopic amount of iron and its radioactivity (/sup 55/Fe) in radioactive corrosion products was established with a single chemical procedure. The iron was first extracted into a liquid scintillator (2,5-diphenyloxazole-xylene) as an ion associate of iron bathophenanthroline (BPT) complex and perchlorate at pH 3-8, followed by measurement of its radioactivity by a liquid scintillation counter and its absorbance by a spectrophotometer. The absorption maximum and molar absorptivity (epsilon) of the complex were 535 nm and 22,000, respectively. The system conforms to Beer's law at concentrations of up to 30 ..mu..g of iron in 10 mL of organic phase. The counting efficiency of the extracted /sup 55/Fe was found to be 60%. Although /sup 60/Co is extracted into the PPO-xylene together with /sup 5/)2%Fe, it is separated from /sup 55/Fe by back extraction with 0.005 M ethylenediaminetetraacetic acid (pH 6.0) into the aqueous phase. The effects of other foreign elements and radionuclides were also examined. The proposed method was successfully applied to analysis of radioactive corrosion products. 21 references, 6 figures, 3 tables.

We study the average separation between an elastic solid and a hard solid with a nominal flat but randomly rough surface, as a function of the squeezing pressure. We present experimental results for a silicon rubber (PDMS) block with a flat surface squeezed against an asphalt road surface. The theory shows that an effective repulse pressure act between the surfaces of the form p proportional to exp(-u/u0), where u is the average separation between the surfaces and u0 a constant of order the root-mean-square roughness, in good agreement with the experimental results.

Neutron scattering studies of crude oil viscosity reduction with electric field  

Science Journals Connector (OSTI)

Abstract The small angle neutron scattering experiment has confirmed the theoretical prediction that a strong electric field induces the suspended nano-particles inside crude oil to aggregate into short chains along the field direction. This aggregation breaks the symmetry, making the viscosity anisotropic: along the field direction, the viscosity is significantly reduced. The experiment enables us to determine the induced chain size and shape, verifies that the electric field works for all kinds of crude oils, paraffin-based, asphalt-based, and mix-based. The basic physics of such field induced viscosity reduction is applicable to all kinds of suspensions.

XANES Identification of Plutonium Speciation in RFETS Samples  

SciTech Connect

Using primarily X-ray absorption near edge spectroscopy (XANES) with standards run in tandem with samples, probable plutonium speciation was determined for 13 samples from contaminated soil, acid-splash or fire-deposition building interior surfaces, or asphalt pads from the Rocky Flats Environmental Technology Site (RFETS). Save for extreme oxidizing situations, all other samples were found to be of Pu(IV) speciation, supporting the supposition that such contamination is less likely to show mobility off site. EXAFS analysis conducted on two of the 13 samples supported the validity of the XANES features employed as determinants of the plutonium valence.

Pipeline refurbishing  

SciTech Connect

A novel process for simultaneously removing deteriorated coatings (such as coal tar and asphalt enamel or tape) and providing surface preparation suitable for recoating has been developed for pipelines up to 36 in. (914 mm) in diameter. This patented device provides a near-white metal surface finish. Line travel or bell-hole operations are possible at rates up to 10 times conventional blasting techniques. This article describes development of a tool and machine that will remove pipeline coatings, including coal tar enamel and adhesive-backed plaster tape systems. After coating removal, the pipe surface is suitable for recoating and can be cleaned to a near-white metal finsh (Sa 2 1/2 or NACE No. 2) if desired. This cleaning system is especially useful where the new coating is incompatible with the coating to be removed, the new coating requires a near-white or better surface preparation, or no existing method has been found to remove the failed coating. This cleaning system can remove all generic coating systems including coal tar enamel, asphalt, adhesive-backed tape, fusion-bonded epoxy, polyester, and extruded polyethylene.

A first step toward a close proximity noise map  

Science Journals Connector (OSTI)

In recent years environmental noise has become a serious issue for civil infrastructure and environmental administration due to public concern over the subject of noise pollution. The most significant deterioration of environmental acoustics conditions comes from road traffic transportation. The predominant noise source is the combination of the tire/pavement interaction and the propulsion systems of the vehicles. Generally tire/pavement interaction is the principal source of noise for speeds above 40 km/h in the case of most modern cars. In this research geo?referenced close proximity rolling noise is used for acoustical characterization of asphalt concrete surfaces in an urban environment. A close proximity noise map of streets with low speed limits is presented for a reference speed of 50 km/h. Different pavements and pavement conditions common in urban streets are analyzed: dense and semidense asphalt concrete with Spanish denomination D?8 and S?12 respectively and on the other hand dense pavement at the end of its service life (D?8*). Noise levels from dense surfaces (D?8) increase significantly over time principally due to the appearance of surface defects such as cracks and ruts.

INTERIM BARRIER AT HANFORDS TY FARM TO PROTECT GROUNDWATER AT THE HANFORD SITE WASHINGTON USA  

SciTech Connect

An innovative interim surface barrier was constructed as a demonstration project at the Hanford Site's TY Tank Farm. The purpose of the demonstration barrier is to stop rainwater and snowmelt from entering the soils within the tank farm and driving contamination from past leaks and spills toward the ground water. The interim barrier was constructed using a modified asphalt material with very low permeability developed by MatCon{reg_sign}. Approximately 2,400 cubic yards of fill material were added to the tank farm to create a sloped surface that will gravity drain precipitation to collection points where it will be routed through buried drain lines to an evapotranspiration basin adjacent to the farm. The evapotranspiration basin is a lined basin with a network of perforated drain lines covered with soil and planted with native grasses. The evapotranspiration concept was selected because it prevents the runoff from percolating into the soil column and also avoids potential monitoring and maintenance issues associated with standing water in a traditional evaporation pond. Because of issues associated with using standard excavation and earth moving equipment in the farm a number of alternate construction approaches were utilized to perform excavations and prepare the site for the modified asphalt.

Selective metal ion extraction for multiple ion liquid-liquid exchange reactions. Progress report, DE-AS02-79ER 10406. A001  

SciTech Connect

The first phase of selecting a model binary system to study was completed. The system selected is Cu(II), Fe(III) acid sulfate solutions extracted by ..beta..-alkenyl 8-hydroxy quinoline (Kelex 100) in xylene. Maximum copper extraction occurs in less than 5 minutes at 30 to 50/sup 0/C. Thermodynamic chemical equilibrium studies with the Fe(III) ion indicate that the ionic charge of the extracted ion is +3 over a limited pH and concentration range. A simplified equilibrium model did not fit the experimental data. A chemical equilibrium model for the aqueous phase was developed. Kinetic studies on the liquid jet recycle reactor are underway. The model proposed to analyze simultaneous extraction of Cu(II) and Fe(III) in a stirred tank extractor was reduced to a set of two nonlinear algebraic equations for idealized kinetic expressions.

Comparison of advanced distillation control methods. Third annual report  

SciTech Connect

Detailed dynamic simulations of three industrial distillation columns (a propylene/propane splitter, a xylene/toluene column, and a depropanizer) have been used to study the issue of configuration selection for diagonal PI dual composition controls, feedforward from a feed composition analyzer, and decouplers. Auto Tune Variation (ATV) identification with on-line detuning for setpoint changes was used for tuning the diagonal proportional integral (PI) composition controls. In addition, robustness tests were conducted by inducting reboiler duty upsets. For single composition control, the (L, V) configuration was found to be best. For dual composition control, the optimum configuration changes from one column to another. Moreover, the use of analysis tools, such as RGA, appears to be of little value in identifying the optimum configuration for dual composition control. Using feedforward from a feed composition analyzer and using decouplers are shown to offer significant advantages for certain specific cases.

Monitoring with the use of passive samplers â?? a useful source of information for the mapping and modelling of urban atmosphere pollution  

Science Journals Connector (OSTI)

Due to human activities, increasing numbers of harmful substances are emitted into the atmosphere; they are recognised as potentially dangerous to living organisms, mainly because of their toxicity. Among others, compounds from the BTEX group, e.g. benzene, toluene, ethylbenzene and xylenes, are considered as such toxic substances. They are present in the air above urbanised as well as rural areas due to their transport in the atmosphere. In order to estimate the human population exposure to the analytes from the BTEX group in the air, it is necessary to monitor the concentration levels of these compounds. The environmental data obtained can be processed further to allow modelling of pollution transport in the atmosphere, and pollution mapping. In this study, literature data on the monitoring of the BTEX concentrations by means of passive dosimetry, and mapping of air pollution from BTEX are presented.

SciTech Connect

The Petro-Chemical Systems, Inc. site, located near Liberty, Texas, is a site where unauthorized disposal of petroleum-based oils has taken place. Although there is evidence of past exposure to site contaminants, the best available evidence does not indicate that humans are currently being exposed to site contaminants at levels that could cause adverse health effects. Contaminated ground water, surface water, soils, and surface water sediments have been found on the site. Although sampling was done for 144 priority pollutants, the primary contaminants of concern are benzene, ethylbenzene, xylene, naphthalene, polycyclic aromatic hydrocarbons, and lead. Because the greatest threat to public health would be contamination of drinking water, the Agency for Toxic Substances and Disease Registry (ATSDR) has recommended that necessary actions are taken to insure that private wells do not become contaminated with site contaminants.

Recovery of propylene glycol from dilute aqueous solutions by reversible chemical complexation with organoboronates  

SciTech Connect

Extractants consisting of an ion-pair of Aliquat 336 with phenylboronate or 3-nitrophenylboronate were prepared in various diluents (2-ethylhexanol, toluene, o-xylene or diisobutylketone). In batch experiments propyleneglycol (1,2-PD) was effectively extracted even at low concentrations. Heterogeneous complexation constants {beta}{sub 11} calculated at 25 C were 45-120 (mol/1){sup {minus}1} in 2-ethylhexanol, 34.8 (mol/l){sup {minus}1} in toluene, 37.6 (mol/l){sup {minus}1} in o-xylene and 14.4 (mol/l){sup {minus}1} in diisobutylketone. In 2-ethythexanol, there was no significant effect of extractant concentration on the complexation constant. Equilibrium water concentration in the extractants was 8-12 wt %, decreasing with 1,2-PD uptake. Nearly all extractant/diluent systems exhibited overloading (more than stoichiometric uptake of 1,2-PD). Evidence for aggregation of the ion-pair extractant in organic phase was found from water solubilization studies (molar solubilization ratios up to 10) and {sup 1}H NMR spectroscopy studies. Solubilization of 1,2-PD within hydrophilic aggregate interiors may explain the observed overloading. The complexation constant decreased with increasing temperature, but not enough to make back extraction after a temperature change attractive. Back extraction may be achieved after acidification with carbon dioxide to convert the organoboronate anion to the corresponding organoboronic acid. Up to 80% of the extracted 1,2-PD was backextracted in a batch extraction using C0{sub 2}. The extractant could then be regenerated by stripping carbon dioxide from solution at temperatures exceeding 110 C. However, at these temperatures the extractant appears to undergo a transformation in which color changes and extraction capacity is reduced to about 60% of original value.

Manhattan Project » Signature Manhattan Project » Signature Facilities » Trinity Site - World's First Nuclear Explosion Trinity Site - World's First Nuclear Explosion Trinity Site - World's First Nuclear Explosion The world's first nuclear explosion occurred on July 16, 1945, when a plutonium implosion device was tested at a site located 210 miles south of Los Alamos on the barren plains of the Alamogordo Bombing Range, known as the Jornada del Muerto. Inspired by the poetry of John Donne, J. Robert Oppenheimer code-named the test Trinity. Hoisted atop a 150-foot tower, the plutonium device, or Gadget, detonated at precisely 5:30 a.m. over the New Mexico desert, releasing 18.6 kilotons of power, instantly vaporizing the tower and turning the surrounding asphalt and sand into green glass.

Strategic benefits Strategic benefits Description Researchers at the University of Wyoming's Western Research Institute (WRI) in Laramie are developing a field upgrading process to help make the conversion and upgrading of bitumen from Canadian oil sands more economical. Bitumen is a highly condensed, semi-solid form of crude oil. It is a natural asphalt that can be hard to recover and refine from tar (oil) sands without the use of expensive enhanced recovery methods. The bitumen must be heated or diluted with lighter hydrocarbons before it can flow readily enough to be piped or trucked from the field to central upgrading facilities or refineries, where it is further distilled to produce lighter products such as diesel fuel and gasoline. Alberta's oil sands contain the

Source, reservoir promise seen in Marathon-Ouachita overthrust  

SciTech Connect

The Permian Basin of West Texas is a prolific oil and gas province that has been extensively explored, but the Marathon-Ouachita overthrust area of Pecos County, Tex., is not fully explored. Rocks of the Ouachita fold belt have been generally regarded by most petroleum geologists as metamorphosed and unsuitable for oil and gas accumulation. Indications of the presence of hydrocarbons in Ouachita rocks have been reported from the earliest days of Permian Basin exploration. Goldstein and Flawn indicated that in the subsurface Ouachita fold belt in Texas asphaltic materials are fairly common in sandstones and cherts. The Ouachita overthrust area in Texas has all the required elements for hydro-carbon accumulation and should be fully explored. This article gives a brief assessment of these elements (traps, source rocks, and reservoirs) in this area.

Change in composition and structure of reduced crudes during conversion on contact material  

SciTech Connect

Four Chinese 350{degrees}C+ reduced crude feedstocks were heated thermally in the presence of a contact material at 480-540{degrees}C in a fixed bed reactor. The feed and products were fractionated into eight fractions using normal pentane precipitation and alumina adsorption chromatography and average molecular parameters calculated with a modified Brown-Ladner method. The results obtained show that the conversion of various fractions of the reduced crudes was quite different. The conversion of asphaltic substances was much higher than those of saturates and aromatics. It is shown that the CH{sub 2}/CH{sub 3} ratio, aromaticity and the numbers of aromatic, naphthenic and total ring of heavy products were obviously lower than those of reduced crudes. The effect of temperature on metal, sulfur, nitrogen removal has been also investigated. The data indicate that the removal of weak polar non-porphyrin nickel was larger than that of middle and strong polar nickel complex.

A Study on the acoustical properties of road surfaces of recycled CFB materials  

Science Journals Connector (OSTI)

Traffic noise and noise control are major concerns of transportation as noise and vibration will cause both psychological and physiological consequences. Great efforts have been made to use more sound absorbent road surfaces in order to reduce traffic noise. The raw materials under study are recycled byproducts from circulating fluidized bed boiler (CFB). The recycled CFB materials have been approved for use by the Environmental and Transportation Departments in various regions throughout the United States for road stabilization and base/surface installations. These (CFB) materials have shown good ecological civil and mechanical properties and are more environmentally friendly than asphalt and concrete. However the acoustical properties of the pavements are not known. Two types of measurements have been conducted. First the traffic noise was measured using the statistical pass-by method on various road surfaces and a comprehensive comparison was conducted. Second the sound absorption coefficients of the CFB materials were measured using impedance tubes.

Characterization of Slow Orbit Motion in the SPEAR3  

SciTech Connect

SPEAR3 is a third-generation synchrotron light source storage ring. The beam stability requirements are {approx}10% of the beam size, which is about 1 micron in the vertical plane. Hydrostatic level system (HLS) measurements show that the height of the SPEAR3 tunnel floor varies by tens of microns daily. We present analysis of the HLS data, including accounting for common-mode tidal motion. We discuss the results of experiments done to determine the primary driving source of ground motion. We painted the accelerator tunnel walls white; we temporarily installed Mylar over the asphalt in the center of the accelerator; and we put Mylar over a section of the tunnel walls.

A Texas project illustrates the benefits of integrated gasification  

SciTech Connect

Gasification can be an attractive option for converting a variety of petroleum feedstocks to chemicals. Natural gas is commonly sued to produce acetic acid, isocyanates, plastics, and fibers. But low-cost, bottom-of-the-barrel feeds, such as vacuum resid, petroleum coke, and asphaltenes, also can be used. In any case, gasification products include synthesis gas, carbon monoxide, hydrogen, steam, carbon dioxide, and power. The more a gasification facility is integrated with utilities and other non-core operations of a production complex, the more economical the products are for all consumers. The paper discusses gasification of natural gas, light hydrocarbons (ethane, propanes, and butanes), and heavy hydrocarbons (distillates, heavy residues, asphalts, coals, petroleum coke). The paper then describes a Texas City Gasification Project, which gasifies methane to produce carbon monoxide, hydrogen, and alcohol. The plant is integrated with a cogeneration plant. Economics are discussed.

Determination of wax deposition and corrosion in pipelines by neutron back diffusion collimation and neutron capture gamma rays  

Science Journals Connector (OSTI)

Wax deposition in pipelines can be very costly for plant operation in oil industry. New techniques are needed for allocation and thickness determination of wax deposits. The timely removal of wax can make large saving in operational cost. Neutron back diffusion and neutron capture gamma rays were used in this study to measure paraffin, asphalt and polyethylene deposition thicknesses inside pipes and to enable simultaneous determination of scale and pipe corrosion. It was possible to determine a thickness change of less than one mm in 2 min. It was also possible to detect localized scale from a small region of the pipe of approximately 2 cm in diameter. Although experiments were performed in lab, the system can be made portable for field applications.

Drag reducers, flow improvers, and other magic potions: slick way to increase capacity  

SciTech Connect

When additional capacity is needed in a given crude oil or products pipeline, the choices are (1) add pumping horsepower at select stations, (2) add pump stations at select locations, (3) add pipeline loops, and (4) use a drag reducer/flow improver. When the need for more capacity is short term, using the slick polymer drag reducing/flow improving chemicals as a fix is likely to prove cheaper and easier. For those operators hampered by waxy or very viscous crudes, other specialty chemicals provide solutions. Availability of specialized chemicals to improve flow conditions in liquids pipelines is increasing. Wax crystal modifier additives are available from several sources. For use with really gunky, almost hard asphalt crudes, an organically-produced emulsion stabilizer has been developed. An in-depth investigation of the products is presented.

Indicators of longitudinal unevenness of roads in the USA  

Science Journals Connector (OSTI)

About 25,800 longitudinal profiles of in-service roads in the USA (Long-Term Pavement Performance (LTPP) Program) were evaluated to obtain indicators of the longitudinal unevenness (roughness) of the road surface defined by standards ISO 8608 : 1995 and EN 13036-5 : 2006. Besides the commonly used International Roughness Index (IRI), also parameters of the Power Spectral Density (PSD) were evaluated taking into account not only the whole interval of effectively acting wavelengths, but also its two and three partial sub-bands. Differences between left and right tracks and between Asphalt Concrete (AC) and Portland Cement Concrete (CC) wearing courses were considered. For all the mentioned indicators (21), their Probability Density Functions (PDF) and numerical statistics were estimated.

Properties of random component of longitudinal road profile influenced by local obstacles  

Science Journals Connector (OSTI)

This paper describes the statistical properties of the pure random component of longitudinal road profile. The individual obstacles were removed from the road profile by median filtering approach. A total of 25,830 test sections records from the long-term pavement performance (LTPP) programme were analysed. The differences between asphalt concrete (AC) and cement concrete (CC) wearing courses were outlined. The comparison was shown on statistics (mean, median, standard deviation values) and probability density functions (PDFs) of contemporary used road indices (international roughness index (IRI), road elevation variance, power spectrum density (PSD) parameters in one-, two- and three-wavelength bands, etc.). The simulation study revealed the marked influence of obstacles on the road indices. The spectral properties of the pure random part were quantified.

Alternative technologies to optical monitoring systems relating to regulatory compliance (Title V)  

SciTech Connect

Due to the development of Title III and Title V of the Clean Air Act Amendments and public awareness of environmentally safe processes, particulate emissions monitoring has become a subject of great importance to the manufacturing sector. An increasing number of monitoring devices are available, and when used in the correct applications, can accurately monitor particulate emissions. This allows identification of a system problem before emissions can reach the stack and trigger non-compliance. This paper focuses on the most widely used technologies for continuous particulate monitoring, specifically the CPM product line, which has been developed to overcome common problems associated with emissions monitoring equipment. Technical data is presented in regard to the CPM operation as well as a case study of a CPM monitor in the asphalt industry.

Use of POTW biosolids in bituminous concrete  

SciTech Connect

Although wastewater treatment helps alleviate water pollution, it creates residual by-products that can pose a disposal dilemma. Four main practices are presently employed to dispose of wastewater treatment plant sludge: land application, composting, incineration, and landfilling. A fifth disposal method that may help to alleviate the sludge disposal problem in future years is the incorporation of sludge into useful end products such as fertilizer or construction materials. This research was designed to evaluate the properties of bituminous concrete mixes that had anaerobically digested sewage sludge incorporated into their design. In doing so, it was desired to verify the work of Wells concerning sludge incorporation into bituminous concrete mixes using today`s asphalts. Hot mix and cold mix designs were studied.

Chapter 5 - Crude Oil  

Science Journals Connector (OSTI)

Abstract Oil has been the number one source of energy in the world since the middle of the twentieth century. The world is very dependent on petroleum for transportation fuels, petrochemicals and asphalt. But ever increasing demand has caused the price of oil to spike in recent years, and only the world economic crisis has been able to temper demand and bring the price down to more reasonable levels. However, the demand and price are likely to shoot up again when the economy recovers. At the same time, the peak oil theory of M. King Hubbert predicts that world oil production is likely to peak soon. This prediction raises questions about what source of energy will come to the fore when oil is not able to keep up.

Oklo: natural fission reactor program. Progress report, July 1-September 30, 1979  

SciTech Connect

Nearly 200 samples were collected at the Oklo mine in Gabon this quarter for shipment to the United States to continue studies of lead, ruthenium, and technetium migration around natural fission reactors. The first analyses of samples collected near a rich uranium ore body in Canada show the presence of radiogenic lead in pyrite and sandstone materials. Analyses of additional samples are underway to permit the interpretation of the data in terms of transport paths. A technique was developed this quarter to eliminate the interference of organic materials during the mass spectrometric analyses of ruthenium in Oklo samples with high asphaltic contents. A proposal was drafted for a study of naturally occurring radionuclide migration at rich uranium ore bodies in Australia to be performed jointly by the US Department of Energy and the Australian Atomic Energy Commission.

Remaining Sites Verification Package for the 100-B-18, 184-B Powerhouse Debris Pile, Waste Site Reclassification Form 2007-020  

SciTech Connect

The 100-B-18 Powerhouse Debris Pile contained miscellaneous demolition waste from the decommissioning activities of the 184-B Powerhouse. The debris covered an area roughly 15 m by 30 m and included materials such as concrete blocks, mixed aggregate/concrete slabs, stone rubble, asphalt rubble, traces of tar/coal, broken fluorescent lights, brick chimney remnants, and rubber hoses. In accordance with this evaluation, the verification sampling results support a reclassification of this site to Interim Closed Out. The results of verification sampling show that residual contaminant concentrations do not preclude any future uses and allow for unrestricted use of shallow zone soils. The results also demonstrate that residual contaminant concentrations are protective of groundwater and the Columbia River.
