The objective of the Cummins ARES program, in partnership with the US Department of Energy (DOE), is to develop advanced natural gas engine technologies that increase engine system efficiency at lower emissions levels while attaining lower cost of ownership. The goals of the project are to demonstrate engine system achieving 50% Brake Thermal Efficiency (BTE) in three phases, 44%, 47% and 50% (starting baseline efficiency at 36% BTE) and 0.1 g/bhp-hr NOx system out emissions (starting baseline NOx emissions at 2 – 4 g/bhp-hr NOx). Primary path towards above goals include high Brake Mean Effective Pressure (BMEP), improved closed cycle efficiency, increased air handling efficiency and optimized engine subsystems. Cummins has successfully demonstrated each of the phases of this program. All targets have been achieved through application of a combined set of advanced base engine technologies and Waste Heat Recovery from Charge Air and Exhaust streams, optimized and validated on the demonstration engine and other large engines. The following architectures were selected for each Phase: Phase 1: Lean Burn Spark Ignited (SI) Key Technologies: High Efficiency Turbocharging, Higher Efficiency Combustion System. In production on the 60/91L engines. Over 500MW of ARES Phase 1 technology has been sold. Phase 2: Lean Burn Technology with Exhaust Waste Heat Recovery (WHR) System Key Technologies: Advanced Ignition System, Combustion Improvement, Integrated Waste Heat Recovery System. Base engine technologies intended for production within 2 to 3 years Phase 3: Lean Burn Technology with Exhaust and Charge Air Waste Heat Recovery System Key Technologies: Lower Friction, New Cylinder Head Designs, Improved Integrated Waste Heat Recovery System. Intended for production within 5 to 6 years Cummins is committed to the launch of next generation of large advanced NG engines based on ARES technology to be commercialized worldwide.

Advanced Natural Gas Reciprocating Engine(s)  

SciTech Connect

Energy independence and fuel savings are hallmarks of the nation’s energy strategy. The advancement of natural gas reciprocating engine power generation technology is critical to the nation’s future. A new engine platform that meets the efficiency, emissions, fuel flexibility, cost and reliability/maintainability targets will enable American manufacturers to have highly competitive products that provide substantial environmental and economic benefits in the US and in international markets. Along with Cummins and Waukesha, Caterpillar participated in a multiyear cooperative agreement with the Department of Energy to create a 50% efficiency natural gas powered reciprocating engine system with a 95% reduction in NOx emissions by the year 2013. This platform developed under this agreement will be a significant contributor to the US energy strategy and will enable gas engine technology to remain a highly competitive choice, meeting customer cost of electricity targets, and regulatory environmental standard. Engine development under the Advanced Reciprocating Engine System (ARES) program was divided into phases, with the ultimate goal being approached in a series of incremental steps. This incremental approach would promote the commercialization of ARES technologies as soon as they emerged from development and would provide a technical and commercial foundation of later-developing technologies. Demonstrations of the Phase I and Phase II technology were completed in 2004 and 2008, respectively. Program tasks in Phase III included component and system development and testing from 2009-2012. Two advanced ignition technology evaluations were investigated under the ARES program: laser ignition and distributed ignition (DIGN). In collaboration with Colorado State University (CSU), a laser ignition system was developed to provide ignition at lean burn and high boost conditions. Much work has been performed in Caterpillar’s DIGN program under the ARES program. This work has consisted of both modeling and single cylinder engine experiments to quantify DIGN performance. The air handling systems of natural gas engines dissipate a percentage of available energy as a result of both flow losses and turbomachinery inefficiencies. An analytical study was initiated to increase compressor efficiency by employing a 2-stage inter-cooled compressor. Caterpillar also studied a turbo-compound system that employs a power turbine to recover energy from the exhaust gases for improved engine efficiency. Several other component and system investigations were undertaken during the final phase of the program to reach the ultimate ARES goals. An intake valve actuation system was developed and tested to improve engine efficiency, durability and load acceptance. Analytical modeling and materials testing were performed to evaluate the performance of steel pistons and compacted graphite iron cylinder head. Effort was made to improve the detonation sensing system by studying and comparing the performance of different pressure sensors. To reduce unburned hydrocarbon emissions, different camshafts were designed and built to investigate the effect of exhaust valve opening timing and value overlap. 1-D & 3-D coupled simulation was used to study intake and exhaust manifold dynamics with the goal of reducing load in-balance between cylinders. Selective catalytic reduction with on-board reductant generation to reduce NOx emissions was also engine tested. An effective mean to successfully deploy ARES technologies into the energy markets is to deploy demonstration projects in the field. In 2010, NETL and Caterpillar agreed to include a new “opportunity fuel” deliverable and two field demonstrations in the ARES program. An Organic Rankine Cycle system was designed with production intent incorporating lessons learned from the Phase II demonstration. Unfortunately, business conditions caused Caterpillar to cancel this demonstration in 2011. Nonetheless, Caterpillar partnered with a local dealer to deploy an ARES class engine using syngas from a biomass gasifier as

Natural gas fueling of a Catepillar 3406 diesel engine  

SciTech Connect

This paper reports on a Caterpillar 3406 turbocharged diesel engine which was converted to operate in a natural gas with diesel pilot ignition mode and was evaluated for performance and emission characteristics for both diesel and natural gas operation. Full-load power was achieved with natural gas fueling without knock. Similar fuel efficiencies were obtained with natural gas fueling at high loads, but efficiencies were lower for low loads. Bosch smoke numbers were reduced by over 50 percent with natural gas fueling for all cases investigated. NO[sub x] emissions were found to be lower at low loads and at high speeds under high load. CO emissions were significantly increased for natural gas fueling while CO[sub 2] concentrations in the exhaust were reduced for natural gas fueling.

Development of the Miller cycle for natural gas engines  

SciTech Connect

Natural gas is a viable alternative fuel to reduce exhaust emissions. But comparing natural gas engines with base diesel engines, the power output is 20--30% lower and the thermal efficiency is 4--5% lower due to knocking in the gas engine. The Miller cycle with independent presetting of the compression and expansion ratio for gas engines increases the engine efficiency with increased expansion ratio, while engine knocking can be avoided by reducing the compression ratio. A turbocharged inter-cooled spark ignition gas engine was modified to the Miller cycle engine and a thermal efficiency of 38%, 1.14MPa BMEP was attained with a three-way catalyst system compared to a thermal efficiency of 33%, 0.97 Mpa BMEP achieved by the conventional Otto cycle. On the other hand, the higher boost pressure, due to the lower compression ratio for avoiding knocking, caused a higher back pressure. This hinders the advantages of the Miller cycle and it is difficult to improve the engine performance further. Therefore, based on the Miller cycle, other technologies for avoiding knocking were developed to improve engine performance. A two-stage intake cooling system was developed, in which a new inter-cooler is installed in the intake passages close to the cylinder head as a second inter-cooler, besides an ordinary charge cooler. This significantly cools the blow-back mixture from the cylinder in the Late Intake-Closing Method Miller cycle. Besides the two-stage intake cooling system, a new split cooling system was also developed for the Miller cycle, where cooling water flowing to the cylinder head is independent of that flowing to the cylinder block. Cooling water at 313 K is circulated in the cylinder head to extend the knock-free zone and to improve the intake charging efficiency while cooling water at 353 K is circulated in the cylinder block to reduce the friction loss.

\\{NOx\\} reduction from a large bore natural gas engine via reformed natural gas prechamber fueling optimization  

Science Journals Connector (OSTI)

Lean combustion is a standard approach used to reduce \\{NOx\\} emissions in large bore (35–56 cm) stationary natural gas engines. However, at lean operating points, combustion instabilities and misfires give rise to high total hydrocarbon (THC) and carbon monoxide (CO) emissions. To counteract this effect, precombustion chamber (PCC) technology is employed to allow engine operation at an overall lean equivalence ratio while mitigating the rise of THC and CO caused by combustion instability and misfires. A PCC is a small chamber, typically 1–2% of the clearance volume. A separate fuel line supplies gaseous fuel to the PCC and a standard spark plug ignites the slightly rich mixture (equivalence ratio 1.1–1.2) in the PCC. The ignited PCC mixture enters the main combustion chamber as a high energy flame jet, igniting the lean mixture in the main chamber. Typically, natural gas fuels both the main chamber and the PCC. In the current research, a mixture of reformed natural gas (syngas) and natural gas fuels the PCC. Syngas is a broad term that refers to a synthetic gaseous fuel. In this case, syngas specifically denotes a mixture of hydrogen, carbon monoxide, nitrogen, and methane generated in a natural gas reformer. Syngas has a faster flame speed and a wider equivalence ratio range of operation than methane. Fueling the PCC with Syngas reduces combustion instabilities and misfires. This extends the overall engine lean limit, enabling further \\{NOx\\} reductions. Research results presented are aimed at quantifying the benefits of syngas PCC fueling. A model is developed to calculate the equivalence ratio in the PCC for different mixtures and flowrates of fuel. An electronic injection valve is used to supply the PCC with syngas. The delivery pressure, injection timing, and flow rate are varied to optimize PCC equivalence ratio. The experimental results show that supplying the PCC with 100% syngas improves combustion stability by 21% compared to natural gas PCC fueling. A comparison at equivalent combustion stability operating points between 100% syngas and natural gas shows an 87% reduction in \\{NOx\\} emissions for 100% syngas PCC fueling compared to natural gas PCC fueling.

Systems for delivering liquified natural gas to an engine  

DOE Patents (OSTI)

A fuel delivery system includes a fuel tank configured to receive liquid natural gas. A first conduit extends from a vapor holding portion of the fuel tank to an economizer valve. A second conduit extends from a liquid holding portion of the fuel tank to the economizer valve. Fluid coupled to the economizer valve is a vaporizer which is heated by coolant from the engine and is positioned below the fuel tank. The economizer valve selectively withdraws either liquid natural gas or vaporized natural gas from the fuel tank depending on the pressure within the vapor holding portion of the fuel tank. A delivery conduit extends from the vaporizer to the engine. A return conduit having a check valve formed therein extends from the delivery conduit to the vapor holding portion of the fuel tank for pressurizing the fuel tank.

Conversion of a diesel engine to a spark ignition natural gas engine  

SciTech Connect

Requirements for alternatives to diesel-fueled vehicles are developing, particularly in urban centers not in compliance with mandated air quality standards. An operator of fleets of diesel- powered vehicles may be forced to either purchase new vehicles or equip some of the existing fleets with engines designed or modified to run on alternative fuels. In converting existing vehicles, the operator can either replace the existing engine or modify it to burn an alternative fuel. Work described in this report addresses the problem of modifying an existing diesel engine to operate on natural gas. Tecogen has developed a technique for converting turbocharged automotive diesel engines to operate as dedicated spark-ignition engines with natural gas fuel. The engine cycle is converted to a more-complete-expansion cycle in which the expansion ratio of the original engine is unchanged while the effective compression ratio is lowered, so that engine detonation is avoided. The converted natural gas engine, with an expansion ratio higher than in conventional spark- ignition natural gas engines, offers thermal efficiency at wide-open- throttle conditions comparable to its diesel counterpart. This allows field conversion of existing engines. Low exhaust emissions can be achieved when the engine is operated with precise control of the fuel air mixture at stoichiometry with a 3-way catalyst. A Navistar DTA- 466 diesel engine with an expansion ratio of 16.5 to 1 was converted in this way, modifying the cam profiles, increasing the turbocharger boost pressure, incorporating an aftercooler if not already present, and adding a spark-ignition system, natural gas fuel management system, throttle body for load control, and an electronic engine control system. The proof-of-concept engine achieved a power level comparable to that of the diesel engine without detonation. A conversion system was developed for the Navistar DT 466 engine. NOx emissions of 1.5 g/bhp-h have been obtained.

Simulation of single acting natural gas Reciprocating Expansion Engine based on ideal gas model  

Science Journals Connector (OSTI)

Abstract The potential energy of high pressure gas destroyed in natural gas pressure reduction stations during pressure reduction when it passes through throttling valves. One way to recover this energy is to use a Reciprocating Expansion Engine coupled with a generator. The expansion engine is able to produce electricity as pressure decreases by recovering the potential energy. Although the expansion engine has been utilized in pressure reduction points for some time but it has not been analyzed for performance enhancement yet. In this work an advanced numerical simulation has been presented for the thermodynamic modeling of Natural Gas Single Acting Reciprocating Expansion Engine under various working conditions for high pressure ranges. The simulation has been carried out to understand the effects of various parameters and to improve performance of the engine. A range of geometric parameters such as suction diameter, piston diameter, crank radius, connecting rod length, speed were covered in this research. Because of the physical and numerical difficulties of the problem, the natural gas is assumed as an ideal gas.

LOW-ENGINE-FRICTION TECHNOLOGY FOR ADVANCED NATURAL-GAS RECIPROCATING ENGINES  

SciTech Connect

This program aims at improving the efficiency of advanced natural-gas reciprocating engines (ANGRE) by reducing piston/ring assembly friction without major adverse effects on engine performance, such as increased oil consumption and emissions. An iterative process of simulation, experimentation and analysis, are being followed towards achieving the goal of demonstrating a complete optimized low-friction engine system. To date, a detailed set of piston/ring dynamic and friction models have been developed and applied that illustrated the fundamental relationships between design parameters and friction losses. Various low-friction strategies and ring-design concepts have been explored, and engine experiments have been done on a full-scale Waukesha VGF F18 in-line 6 cylinder power generation engine rated at 370 kW at 1800 rpm. Current accomplishments include designing and testing ring-packs using a subtle top-compression-ring profile (skewed barrel design), lowering the tension of the oil-control ring, employing a negative twist to the scraper ring to control oil consumption. Initial test data indicate that piston ring-pack friction was reduced by 35% by lowering the oil-control ring tension alone, which corresponds to a 1.5% improvement in fuel efficiency. Although small in magnitude, this improvement represents a first step towards anticipated aggregate improvements from other strategies. Other ring-pack design strategies to lower friction have been identified, including reduced axial distance between the top two rings, tilted top-ring groove. Some of these configurations have been tested and some await further evaluation. Colorado State University performed the tests and Waukesha Engine Dresser, Inc. provided technical support. Key elements of the continuing work include optimizing the engine piston design, application of surface and material developments in conjunction with improved lubricant properties, system modeling and analysis, and continued technology demonstration in an actual full-sized reciprocating natural-gas engine.

This program aims at improving the efficiency of advanced natural-gas reciprocating engines (ANGRE) by reducing piston and piston ring assembly friction without major adverse effects on engine performance, such as increased oil consumption and wear. An iterative process of simulation, experimentation and analysis is being followed towards achieving the goal of demonstrating a complete optimized low-friction engine system. To date, a detailed set of piston and piston-ring dynamic and friction models have been developed and applied that illustrate the fundamental relationships between design parameters and friction losses. Low friction ring designs have already been recommended in a previous phase, with full-scale engine validation partially completed. Current accomplishments include the addition of several additional power cylinder design areas to the overall system analysis. These include analyses of lubricant and cylinder surface finish and a parametric study of piston design. The Waukesha engine was found to be already well optimized in the areas of lubricant, surface skewness and honing cross-hatch angle, where friction reductions of 12% for lubricant, and 5% for surface characteristics, are projected. For the piston, a friction reduction of up to 50% may be possible by controlling waviness alone, while additional friction reductions are expected when other parameters are optimized. A total power cylinder friction reduction of 30-50% is expected, translating to an engine efficiency increase of two percentage points from its current baseline towards the goal of 50% efficiency. Key elements of the continuing work include further analysis and optimization of the engine piston design, in-engine testing of recommended lubricant and surface designs, design iteration and optimization of previously recommended technologies, and full-engine testing of a complete, optimized, low-friction power cylinder system.

Abstract As global energy demand rises, natural gas (NG) plays an important strategic role in energy supply. Natural gas is the cleanest fossil fuel that has been investigated extensively for use in spark-ignition (SI) and compression-ignition (CI) engines. This paper reviews the research on the effects of natural gas composition on combustion and emission characteristics of natural gas fueled internal combustion engines (ICEs) and reports the most achievements obtained by researchers in this field. It has been reported that the engine performance and emission are greatly affected by varying compositions of natural gas. The most important NG fuel property is the Wobbe number (WN). Generally, it was agreed by researchers that the fuels with higher hydrocarbons, higher WN, and higher energy content exhibited better fuel economy and carbon dioxide (CO2) emissions. Nitrogen oxides (NOx) emissions were also increased for gases with higher levels of higher WN, while total hydrocarbons (THCs), carbon monoxide (CO), showed some reductions for these gases. On the other hand, particulate matter (PM) emissions did not show any fuel effects. Moreover, adding of small fractions of higher alkanes, such as ethane and propane, significantly improved ignition qualities of natural gas engines. The results presented provide a good insight for researchers to pursue their future research on natural gas fueled ICEs.

An experimental investigation of high performance natural gas engine with direct injection  

Science Journals Connector (OSTI)

This paper presents experimental results of a new compressed natural gas direct injection (CNG-DI) engine that has been developed from modification of a multi cylinder gasoline port injection (PI) engine. The original gasoline-PI engine was also modified to a CNG bi-fuel system. The test results obtained from CNG fuel using two different systems (i.e. bi-fuel and DI) have been investigated and compared with the original gasoline engine. The objective of this investigation is to compare the test results between CNG-DI, with CNG-BI and gasoline-PI engines with the same displacement volume. It was found that the CNG-DI engine produces similar brake power at 6000 rpm and wide open throttle (WOT) but produces higher brake power at part load condition as compared to the original gasoline. The CNG-BI engine produces 23% lower brake power than the CNG-DI engine. The average brake specific fuel consumption (BSFC) of the CNG-DI engine was 0.28% and 8% lower than gasoline-PI and CNG-BI engines respectively. The CNG-DI engine reduces 42% \\{NOx\\} emission as compared to the base engine. However, the CNG-DI engine produces higher HC and CO emissions as compared to the base engine. This paper discusses a review on the direct injection (DI) natural gas engine with new information along with other investigations.

Stirling Engine Natural Gas Combustion Demonstration Program. Final report, October 1989-January 1991  

SciTech Connect

Fueled on natural gas, the Stirling engine is an inherently clean, quiet, and efficient engine. With increasing environmental concern for air quality and the increasingly more stringent requirements for low engine exhaust emissions, the Stirling engine may be an attractive alternative to internal combustion (IC) engines. The study has demonstrated that ultra low emissions can be attained with a Stirling-engine-driven electric generator configured to burn natural gas. Combustion parameters were optimized to produce the lowest possible exhaust emissions for a flame-type combustor without compromising overall engine thermal efficiency. A market application survey and manufacturing cost analysis indicate that a market opportunity potentially exists in the volumes needed to economically manufacture a newly designed Stirling engine (Mod III) for stationary applications and hybrid vehicles. The translation of such potential markets into actual markets does, however, pose difficult challenges as substantial investments are required. Also, the general acceptance of a new engine type by purchasers requires a considerable amount of time.

STATE OF THE ART AND FUTURE DEVELOPMENTS IN NATURAL GAS ENGINE TECHNOLOGIES  

SciTech Connect

Current, state of the art natural gas engines provide the lowest emission commercial technology for use in medium heavy duty vehicles. NOx emission levels are 25 to 50% lower than state of the art diesel engines and PM levels are 90% lower than non-filter equipped diesels. Yet, in common with diesel engines, natural gas engines are challenged to become even cleaner and more efficient to meet environmental and end-user demands. Cummins Westport is developing two streams of technologies to achieve these goals for medium-heavy and heavy-heavy duty applications. For medium-heavy duty applications, lowest possible emissions are sought on SI engines without significant increase in complexity and with improvements in efficiency and BMEP. The selected path builds on the capabilities of the CWI Plus technology and recent diesel engine advances in NOx controls, providing potential to reduce emissions to 2010 values in an accelerated manner and without the use of Selective Catalytic Reduction or NOx Storage and Reduction technology. For heavy-heavy duty applications where high torque and fuel economy are of prime concern, the Westport-Cycle{trademark} technology is in field trial. This technology incorporates High Pressure Direct Injection (HPDI{trademark}) of natural gas with a diesel pilot ignition source. Both fuels are delivered through a single, dual common rail injector. The operating cycle is entirely unthrottled and maintains the high compression ratio of a diesel engine. As a result of burning 95% natural gas rather than diesel fuel, NOx emissions are halved and PM is reduced by around 70%. High levels of EGR can be applied while maintaining high combustion efficiency, resulting in extremely low NOx potential. Some recent studies have indicated that DPF-equipped diesels emit less nanoparticles than some natural gas vehicles [1]. It must be understood that the ultrafine particles emitted from SI natural gas engines are generally accepted to consist predominantly of VOCs [2], and that lubricating oil is a major contributor. Fitting an oxidation catalyst to the natural gas engine leads to a reduction in nanoparticles emissions in comparison to engines without aftertreatment [2,3,4]. In 2001, the Cummins Westport Plus technology was introduced with the C Gas Plus engine, a popular choice for transit bus applications. This incorporates drive by wire, fully integrated, closed loop electronic controls and a standard oxidation catalyst for all applications. The B Gas Plus and the B Propane Plus engines, with application in shuttle and school buses were launched in 2002 and 2003. The gas-specific oxidation catalyst operates in concert with an optimized ring-pack and liner combination to reduce total particulate mass below 0.01g/bhphr, combat ultrafine particles and control VOC emissions.

Lean Burn Natural Gas Engine R&D  

SciTech Connect

The primary objective of this cooperative research is to develop and verify models of internal combustion engine spark ignition devices in order to improve combustion chamber fuel ignition characteristics and to improve spark plug durability. As a direct result of this joint research, a novel spark plug design was improved. A theory of spark arc motion was developed that explains experimentally observed effects not explained by other published theories. The knowledge developed by this research will be used to further improve spark plugs as well as improve the ignition process in a combustion chamber. The predictive models developed here are compared with experimental measurements, including high-speed photographs, of the spark as it translates across the gap. Two different spark plug configurations were investigated: the conventional or J-gap plug, and a novel spark ignition device (the FANG plug) invented by Cummins, Inc., the CRADA partner. A description of the physics of arc dynamic motion in a spark plug gap, including the effects of an imposed transverse magnetic field, appears here in Appendix A as a result of the analytical effort. The theory proposed here does explain experimentally observed effects not completely explained by other research publications appearing in the scientific literature. These effects are due to pressure and ion, electron, and electrode interactions. A dominant mechanism for electrode erosion is presented for both spark plug configurations. Reversing the polarity of both types of spark plugs has verified this proposed erosion mechanism, according to data collected at Cummins. An extensive series of experiments measured the arc position, voltage, and current as a function of time during the approximately 2 millisecond spark discharge. FANG plug data, obtained with the fast-framing camera experimental apparatus operating at 200,000 frames per second, are presented that show the transverse arc velocity varying directly as the inverse square root of the elapsed time since arc initiation. At the request of Cummins, experiments were performed on three conventional spark plugs identical in design and having the same spark gap, but differing as follows: one was new, another had been used in an engine, and the third was new but had been sandblasted to simulate a used plug. Cummins had observed that only the used plug required a significantly higher breakdown voltage. Experiments at ORNL indicated that the used plug had a significantly higher breakdown voltage confirming the Cummins observations (although the sandblasted plug also exhibited a higher breakdown voltage than the new plug but lower than the used plug), and thus an apparent increase of the arc breakdown voltage results as the plug ages in use. Further analysis of this phenomenon is warranted.

Emissions and fuel economy of a prechamber diesel engine with natural gas dual fuelling  

SciTech Connect

A four-cylinder turbocharged prechamber diesel engine (Caterpillar 3304) was operated with natural gas and pilot diesel fuel ignition over a wide range of load and speed. Measurements were made of fuel consumption and the emissions of unburned hydrocarbons, carbon monoxide, and the oxides of nitrogen. Improvements in fuel economy and emissions were found to be affected by the diesel fuel-gas fraction, and by air restriction and fuel injection timing. Boundaries of unstable, inefficient and knocking operation were defined and the importance of gas-air equivalance ratio was demonstrated in its effect on economy, emissions and stability of operation.

High-pressure late cycle direct injection of natural gas in a rail medium speed diesel engine  

SciTech Connect

The performance of an Electro-Motive Division (EMD) 567B, two-cylinder locomotive research engine, when operated on high-pressure/late-cycle injection of natural gas, is presented in this paper. A redesign and fabrication of the fuel system was undertaken to facilitate the consumption of natural gas. A small percentage of No.2 diesel fuel (DF-2) was used to ignite the natural gas. Engine performance, while running natural gas, resulted in matching rated speed and power with slightly lower thermal efficiency. Full power was achieved with a ratio of 99 percent natural gas and 1 percent diesel fuel. However, at high natural gas to diesel fuel ratios, audible knock was detected. The primary objective of the project was to establish technical feasibility of, and basic technology for, operating medium-speed rail diesel engines on high-pressure natural gas. Secondary objectives were to attain adequate engine performance levels for rail application, develop a system oriented toward retrofit of in-service locomotives, and realize any potential improvements in thermal efficiency due to use of the high-pressure/late-cycle approach.

Although natural gas is a nonrenewable resource, it is included for discussion because its sudden growth from fracking will impact the development and use of renewable fuels. Firms who are engaged in the development of processes that employ synthesis gas as an intermediate have concluded that the synthesis gas is more economically obtainable by steam reforming of natural gas than by gasification of waste cellulose. In some instances, firms have largely abandoned the effort to produce a renewable fuel as such, and in others firms are developing hybrid processes that employ natural gas in combination with a fermentation system. Moreover, natural gas itself is an attractive fuel for internal combustion engines since it can be the least expensive option on a cost per joule basis. It is also aided by its high octane number of 130.

Experimental investigation of thermal balance of a turbocharged SI engine operating on natural gas  

Science Journals Connector (OSTI)

Abstract This paper experimentally investigates the thermal balance and performance of a turbocharged gas spark ignition engine. The First Law of Thermodynamics was used for control volume around the engine to compute the output power, transferred energy to the cooling fluid, exhaust gases and also unaccounted losses through convection and radiation heat transfer. Thermal balance tests were performed for various operational conditions including full and half loads and different cooling fluid temperatures. Results indicate that by increasing engine load and coolant temperature, the percentage of transferred energy to the exhaust gases increased while the percentage of coolant energy decreased. Also, experimental data reveals that using gaseous fuel and a turbocharger (TC) in the engine leads to 4.5% and 4% more thermal efficiency than gasoline and natural aspirated (NA), respectively. Also, second law analysis reveals that using a turbocharger leads to a 3.6% increase in exergetic efficiency of the engine, averagely. Based on experimental results, an empirical correlation was suggested for computing the energy of exhaust gases which shows good agreement with the experimental data for the majority of operating conditions.

Evaluation of Technical Feasibility of Homogeneous Charge Compression Ignition (HCCI) Engine Fueled with Hydrogen, Natural Gas, and DME  

SciTech Connect

The objective of the proposed project was to confirm the feasibility of using blends of hydrogen and natural gas to improve the performance, efficiency, controllability and emissions of a homogeneous charge compression ignition (HCCI) engine. The project team utilized both engine simulation and laboratory testing to evaluate and optimize how blends of hydrogen and natural gas fuel might improve control of HCCI combustion. GTI utilized a state-of-the art single-cylinder engine test platform for the experimental work in the project. The testing was designed to evaluate the feasibility of extending the limits of HCCI engine performance (i.e., stable combustion, high efficiency and low emissions) on natural gas by using blends of natural gas and hydrogen. Early in the project Ricardo provided technical support to GTI as we applied their engine performance simulation program, WAVE, to our HCCI research engine. Modeling support was later provided by Digital Engines, LLC to use their proprietary model to predict peak pressures and temperatures for varying operating parameters included in the Design of Experiments test plan. Digital Engines also provided testing support for the hydrogen and natural gas blends. Prof. David Foster of University of Wisconsin-Madison participated early in the project by providing technical guidance on HCCI engine test plans and modeling requirements. The main purpose of the testing was to quantify the effects of hydrogen addition to natural gas HCCI. Directly comparing straight natural gas with the hydrogen enhanced test points is difficult due to the complexity of HCCI combustion. With the same air flow rate and lambda, the hydrogen enriched fuel mass flow rate is lower than the straight natural gas mass flow rate. However, the energy flow rate is higher for the hydrogen enriched fuel due to hydrogen’s significantly greater lower heating value, 120 mJ/kg for hydrogen compared to 45 mJ/kg for natural gas. With these caveats in mind, an analysis of test results indicates that hydrogen enhanced natural gas HCCI (versus neat natural gas HCCI at comparable stoichiometry) had the following characteristics: • Substantially lower intake temperature needed for stable HCCI combustion • Inconclusive impact on engine BMEP and power produced, • Small reduction in the thermal efficiency of the engine, • Moderate reduction in the unburned hydrocarbons in the exhaust, • Slight increase in NOx emissions in the exhaust, • Slight reduction in CO2 in the exhaust. • Increased knocking at rich stoichiometry The major accomplishments and findings from the project can be summarized as follows: 1. A model was calibrated for accurately predicting heat release rate and peak pressures for HCCI combustion when operating on hydrogen and natural gas blends. 2. A single cylinder research engine was thoroughly mapped to compare performance and emissions for micro-pilot natural gas compression ignition, and HCCI combustion for neat natural gas versus blends of natural gas and hydrogen.

Characterization of cycle-to-cycle variations in a natural gas spark ignition engine  

Science Journals Connector (OSTI)

Abstract In this work a study of the influence of the fuel/air equivalence ratio and engine rotational speed on the cycle-to-cycle variations in combustion in a natural gas spark ignition engine is presented. The study considers both classic estimators of cyclic dispersion and a new one, based on the burned mass and burning rate. The engine experimental conditions were as follows: Intake pressure 0.5 bar, while fuel/air equivalence ratio was changed from 1.0 to 0.63, and engine rotational speed was varied from 1000 rpm to 2500 rpm. For each equivalence ratio and engine speed, a diagnosis model is used to process the experimentally obtained combustion pressure data in order to provide combustion relevant results such as the mass burning rate at a cycle level. A procedure based on the use of genetic algorithms is used to obtain a very accurate and objective (without human intervention) adjustment of the optimum parameters needed for combustion diagnosis: angular positioning and pressure offset of the pressure register, dynamic compression ratio, and heat transfer coefficients. The model allows making the diagnosis of series of 830 consecutive engine cycles in an automatic way, increasing the objectivity of the combustion diagnosis. The paper focuses on using the values of the mass fraction burned computed from the pressure register and especially on the analysis of the combustion cycle to cycle variation in the natural gas fuelled engine. A new indicator for the study of cycle-to-cycle variations is proposed, i.e. the standard deviation of the mass fraction burning rate. The values of this new indicator are compared with other classic indicators, showing the same general trends. However, a deeper insight is provided on the combustion cyclic variation when the values of the new indicator are plotted as a function of the mass fraction burned, since this allows analyzing the cyclic variation along the combustion development in each cycle from a mass fraction burned of zero to one, with a relevant value at mass fraction burned of 0.5. More important is that the consideration of the dependence of the combustion variables (density, flame front surface, combustion speed) on the mass fraction burned allows ensemble averaging of all registered cycles for each value of mass fraction burned. This permits using the ensemble averaged mass fraction burning rate as an estimator of combustion speed. The analysis of the general trends of cyclic dispersion when engine speed and equivalence ratio are modified (1000, 1750 and 2500 rpm; 0.7, 0.8, 0.9 and 1.0) indicate that cycle-to-cycle variations show, as expected, a strong dependence on the engine rotational speed, increasing the variation with engine rpm. However, when the standard deviation of mass fraction burning rate is plotted as a function of mass fraction burned, there is a linear dependence on engine rpm, but only a very weak dependence on equivalence ratio. This means that the proposed estimator of cyclic dispersion is sensitive to only flow turbulent intensity and not to equivalence ratio.

Advanced natural-gas-fueled-engine development. Part 1: design and analyses. Final report, April 1985-July 1986  

SciTech Connect

The objective of the research program was to design an advanced natural gas engine (NG 1990) to be produced in the 1990's which will have high thermal efficiency and 40,000 hours durability of the valve-train components before major engine overhaul. Preliminary design and feasibility of the NG 1990 advanced natural gas engine was completed. A natural gas engine simulation model predicts up to 43.6% brake thermal efficiency (5840 Btu/hp-hr BSFC) for the advanced engine with the advanced concepts like K-Miller cycle (early intake valve closing), lean burn combustion - A/F ratio = 24.5, high compression ratio up to 14:1, higher turbocharger efficiency of 63.2% overall, and axially stratified charge combustion system resulting in fast burning. The use of K-Miller cycle reduces the in-cylinder gas temperatures and allows engine operation at 14:1 compression ratio without knock tendencies. The design and analyses of the NG 1990 engine and its components like K-Miller system were completed in the program.

Development of a direct-injected natural gas engine system for heavy-duty vehicles: Final report phase 2  

SciTech Connect

This report summarizes the results of Phase 2 of this contract. The authors completed four tasks under this phase of the subcontract. (1) They developed a computational fluid dynamics (CFD) model of a 3500 direct injected natural gas (DING) engine gas injection/combustion system and used it to identify DING ignition/combustion system improvements. The results were a 20% improvement in efficiency compared to Phase 1 testing. (2) The authors designed and procured the components for a 3126 DING engine (300 hp) and finished assembling it. During preliminary testing, the engine ran successfully at low loads for approximately 2 hours before injector tip and check failures terminated the test. The problems are solvable; however, this phase of the program was terminated. (3) They developed a Decision & Risk Analysis model to compare DING engine technology with various other engine technologies in a number of commercial applications. The model shows the most likely commercial applications for DING technology and can also be used to identify the sensitivity of variables that impact commercial viability. (4) MVE, Inc., completed a preliminary design concept study that examines the major design issues involved in making a reliable and durable 3,000 psi LNG pump. A primary concern is the life of pump seals and piston rings. Plans for the next phase of this program (Phase 3) have been put on indefinite hold. Caterpillar has decided not to fund further DING work at this time due to limited current market potential for the DING engine. However, based on results from this program, the authors believe that DI natural gas technology is viable for allowing a natural gas-fueled engine to achieve diesel power density and thermal efficiency for both the near and long terms.

Gas-Fired Reciprocating Engines  

Energy.gov (U.S. Department of Energy (DOE))

The reciprocating, or piston-driven, engine is a widespread and well-known technology. Also called internal combustion engines, reciprocating engines require fuel, air, compression, and a combustion source to function. Depending on the ignition source, they generally fall into two categories: (1) spark-ignited engines, typically fueled by gasoline or natural gas, and (2) compression-ignited engines, typically fueled by diesel oil fuel.

Natural gas vehicles (NGVs) are either fueled exclusively with compressed natural gas or liquefied natural gas (dedicated NGVs) or are capable of natural gas and gasoline fueling (bi-fuel NGVs). Dedicated NGVs are designed to run only on natural gas. Bi-fuel NGVs have two separate fueling systems that enable the vehicle to use either natural gas or a conventional fuel (gasoline or diesel). In general, dedicated natural gas vehicles demonstrate better performance and have lower emissions than bi-fuel vehicles because their engines are optimized to run on natural gas. In addition, the vehicle does not have to

Dual-fuel natural gas/diesel engines: Technology, performance, and emissions. Topical report, February 1993-November 1994  

SciTech Connect

An investigation of current dual-fuel natural gas/diesel engine design, performance, and emissions was conducted. The most pressing technological problems associated with dual-fuel engine use were identified along with potential solutions. It was concluded that dual-fuel engines can achieve low NOx and particulate emissions while retaining fuel-efficiency and BMEP levels comparable to those of diesel engines. The investigation also examined the potential economic impact of dual-fuel engines in diesel-electric locomotives, marine vessels, farm equipment, construction, mining, and industrial equipment, and stand-alone electricity generation systems. Recommendations for further additional funding to support research, development, and demonstration in these applications were then presented.

Thermodynamic analysis of an HCCI engine based system running on natural gas  

Science Journals Connector (OSTI)

Abstract This paper attempts to carry out a thermodynamic analysis of a system composed of a turbocharged HCCI engine, a mixer, a regenerator and a catalytic converter within the meaning of the first and the second law of thermodynamics. For this purpose, a thermodynamic model has been developed taking into account the gas composition resulting from the combustion process and the specific heat temperature dependency of the working fluid. The analysis aims in particular to examine the influence of the compressor pressure ratio, ambient temperature, equivalence ratio, engine speed and the compressor isentropic efficiency on the performance of the HCCI engine. Results show that thermal and exergetic efficiencies increase with increasing the compressor pressure ratio. However, the increase of the ambient temperature involves a decrease of the engine efficiencies. Furthermore, the variation of the equivalence ratio improves considerably both thermal and exergetic efficiencies. As expected, the increase of the engine speed enhances the engine performances. Finally, an exergy losses mapping of the system show that the maximum exergy losses occurs in the HCCI engine.

Fundamental Studies of Ignition Process in Large Natural Gas Engines Using Laser Spark Ignition  

SciTech Connect

Past research has shown that laser ignition provides a potential means to reduce emissions and improve engine efficiency of gas-fired engines to meet longer-term DOE ARES (Advanced Reciprocating Engine Systems) targets. Despite the potential advantages of laser ignition, the technology is not seeing practical or commercial use. A major impediment in this regard has been the 'open-path' beam delivery used in much of the past research. This mode of delivery is not considered industrially practical owing to safety factors, as well as susceptibility to vibrations, thermal effects etc. The overall goal of our project has been to develop technologies and approaches for practical laser ignition systems. To this end, we are pursuing fiber optically coupled laser ignition system and multiplexing methods for multiple cylinder engine operation. This report summarizes our progress in this regard. A partial summary of our progress includes: development of a figure of merit to guide fiber selection, identification of hollow-core fibers as a potential means of fiber delivery, demonstration of bench-top sparking through hollow-core fibers, single-cylinder engine operation with fiber delivered laser ignition, demonstration of bench-top multiplexing, dual-cylinder engine operation via multiplexed fiber delivered laser ignition, and sparking with fiber lasers. To the best of our knowledge, each of these accomplishments was a first.

Experimental investigation of DI diesel engine operating with eucalyptus biodiesel/natural gas under dual fuel mode  

Science Journals Connector (OSTI)

Abstract With the gradual depletion of petroleum and environmental degradation, intensive research activity has been addressed to the utilization of alternative fuels in internal combustion engines. In the present work, an experimental investigation is carried out to study the effect of eucalyptus biodiesel and natural gas under dual fuel combustion mode on the performance and the exhaust emissions of a single cylinder DI diesel engine. The natural gas (NG) is inducted with the intake air through the inlet manifold. The liquid pilot fuel (eucalyptus biodiesel or diesel fuel) is injected into the combustion chamber to cover approximately 10% of the maximum power output. Then, keeping constant the pilot fuel flow rate, the power output is further increased using only natural gas. The combustion characteristics (cylinder pressure, ignition delay and heat release rate), performance and exhaust emissions of the dual fuel mode (NG–diesel fuel and NG–biodiesel) are compared with those of conventional diesel engine mode at various load conditions. The combustion analysis has shown that biodiesel as pilot fuel exhibits similar pressure–time history, with highest peak, as diesel fuel in conventional and dual fuel modes. The performance and pollutant emission results show that, compared to diesel fuel in dual fuel mode, the use of eucalyptus biodiesel as pilot fuel reduces the high emission levels of unburned hydrocarbon (HC), carbon monoxide (CO) and carbon dioxide (CO2) particularly at high engine loads. However this is accompanied by an increase in the brake specific fuel consumption (BSFC) and the nitrogen oxide (NOx) emissions, which can be explained by the lower calorific value and the oxygen presence in the molecule of the eucalyptus biodiesel, respectively.

PV output smoothing using a battery and natural gas engine-generator.  

SciTech Connect

In some situations involving weak grids or high penetration scenarios, the variability of photovoltaic systems can affect the local electrical grid. In order to mitigate destabilizing effects of power fluctuations, an energy storage device or other controllable generation or load can be used. This paper describes the development of a controller for coordinated operation of a small gas engine-generator set (genset) and a battery for smoothing PV plant output. There are a number of benefits derived from using a traditional generation resource in combination with the battery; the variability of the photovoltaic system can be reduced to a specific level with a smaller battery and Power Conditioning System (PCS) and the lifetime of the battery can be extended. The controller was designed specifically for a PV/energy storage project (Prosperity) and a gas engine-generator (Mesa Del Sol) currently operating on the same feeder in Albuquerque, New Mexico. A number of smoothing simulations of the Prosperity PV were conducted using power data collected from the site. By adjusting the control parameters, tradeoffs between battery use and ramp rates could be tuned. A cost function was created to optimize the control in order to balance, in this example, the need to have low ramp rates with reducing battery size and operation. Simulations were performed for cases with only a genset or battery, and with and without coordinated control between the genset and battery, e.g., without the communication link between sites or during a communication failure. The degree of smoothing without coordinated control did not change significantly because the battery dominated the smoothing response. It is anticipated that this work will be followed by a field demonstration in the near future.

Feasibility study of a 6V-92TA homogeneous auto-ignited two-stroke (HAT) compressed-natural-gas-engine. Topical report, August 1989-May 1990  

SciTech Connect

The objective of the project was to modify a two-stroke 6V-92TA diesel engine to operate on natural gas using a simple system with gas addition to the compressor inlet and a spark plug for cold start and non-autoignition engine operation. The engine was to be operated at most speed-load conditions by autoignition of the premixed gas-air mixture. This concept is referred to as the Homogeneous Auto-Ignited Two-Stroke (HAT). Autoignition of carbureted natural gas was achieved at various loads and speeds in a 6V-92TA engine modified for operating on natural gas with the HAT concept. However, HAT engine operation up to 277 hp at 2100 rpm (diesel coach rating) was not achieved because early ignition in some cylinders caused knock and excessive heat transfer. Instead, the engine was operated up to 226 hp (767 N.m) at 2100 rpm, 181 hp (780 N.m) at 1650 rpm, 130 hp (773 N.m) at 1200 rpm, and 34 hp (368 N.m) at 650 rpm. Maximum brake thermal efficiency measured was 33.4% at 2100 rpm/219 hp. The corrected efficiency (to compensate for the unburned natural gas lost during the scavenging process) was higher than this. Steady-state emissions show very low NOx, total unburned HC lower than expected and reasonable CO levels. The lean air-fuel mixture and unburned exhaust gases in the cylinder resulted in very low NOx emissions.

Natural Gas Research Natural Gas Research Natural gas offers tremendous opportunities for reducing the use of petroleum in transportation. Medium and heavy-duty fleets, which have significant potential to use natural gas, currently consume more than a third of the petroleum in transportation in the U.S. Natural gas is an excellent fit for a wide range of heavy-duty applications, especially transit buses, refuse haulers, and Class 8 long-haul or delivery trucks. In addition, natural gas can be a very good choice for light-duty vehicle fleets with central refueling. See the Alternative Fuels Data Center for a description of the uses and benefits of natural gas vehicles or its Laws and Incentives database for information on tax incentives. The Vehicle Technologies Office (VTO) supports the development of natural gas engines and research into renewable natural gas production.

Experimental study on combustion characteristics of a spark-ignition engine fueled with natural gas–hydrogen blends combining with EGR  

Science Journals Connector (OSTI)

An experimental study on the effect of hydrogen fraction and EGR rate on the combustion characteristics of a spark-ignition engine fueled with natural gas–hydrogen blends was investigated. The results show that flame development duration, rapid combustion duration and total combustion duration are increased with the increase of EGR rate and decreased with the increase of hydrogen fraction in the blends. Hydrogen addition shows larger influence on flame development duration than that on rapid combustion duration. The coefficient of variation of the indicated mean effective pressure increases with the increase of EGR rate. And hydrogen addition into natural gas decreases the coefficient of variation of the indicated mean effective pressure, and this effectiveness becomes more obviously at high EGR rate. Engine fueled with natural gas–hydrogen blends combining with proper EGR rate can realize the stable low temperature combustion in gas engine.

Impact of Interruptible Natural Gas Service A Snapshot of California Natural Gas Market: Status and Outlook EIA's Testimony on Natural Gas Supply and Demand Residential Natural Gas Price Brochure Status of Natural Gas Pipeline System Capacity Previous Issues of Natural Gas Weekly Update Natural Gas Homepage Overview Net additions to storage during the fourth week of April were estimated to have been over 100 Bcf-a record high level for the first month of the refill season. Compared to last year when only 36 Bcf or 1.2 Bcf per day were added to stocks in April, this year the industry appears to be taking advantage of the reduction in demand that typically occurs in April, the first shoulder month of the year, and the recent price declines. After beginning the week down, spot prices at the Henry Hub trended down most days last week to end trading on Friday at $4.49 per MMBtu-the lowest price since early November. On the NYMEX futures market, the near-month (June) contract also moved down most days and ended last week at $4.490-down $0.377 from the previous Friday. Some-early summer high temperatures last week in the Northeast and winter-like weather in the Rockies (See Temperature Map) (See Deviation from Normal Temperatures Map) appear to have had little impact on the natural gas markets as prices declined most days at most major locations.

The Natural Gas Advantage  

Science Journals Connector (OSTI)

Environmental think-tank leaders and the new energy secretary are singing the praises of the ever-expanding U.S. natural gas bonanza, but at the same time, they worry about permanent dependence on this fossil fuel. ... This flood of shale-based natural gas finds has been great for U.S. chemical companies because it is a cheap feedstock and fuel source. ... Equally important, it is also revising the greenhouse gas-climate change equation because, when burned to generate electricity, natural gas produces the same electrical output as coal but emits half the amount of carbon dioxide. ...

Multi-zone modelling of partially premixed low-temperature combustion in pilot-ignited natural-gas engines  

SciTech Connect

Detailed results from a multi-zone phenomenological simulation of partially premixed advanced-injection low-pilot-ignited natural-gas low-temperature combustion are presented with a focus on early injection timings (the beginning of (pilot) injection (BOI)) and very small diesel quantities (2-3 per cent of total fuel energy). Combining several aspects of diesel and spark ignition engine combustion models, the closed-cycle simulation accounted for diesel autoignition, diesel spray combustion, and natural-gas combustion by premixed turbulent flame propagation. The cylinder contents were divided into an unburned zone, several pilot fuel zones (or 'packets') that modelled diesel evaporation and ignition, a flame zone for natural-gas combustion, and a burned zone. The simulation predicted the onset of ignition, cylinder pressures, and heat release rate profiles satisfactorily over a wide range of BOIs (20-60���° before top dead centre (before TDC)) but especially well at early BOIs. Strong coupling was observed between pilot spray combustion in the packets and premixed turbulent combustion in the flame zone and, therefore, the number of ignition centres (packets) profoundly affected flame combustion. The highest local peak temperatures (greater than 2000 K) were observed in the packets, while the flame zone was much cooler (about 1650 K), indicating that pilot diesel spray combustion is probably the dominant source of engine-out emissions of nitrogen oxide (NO x). Further, the 60���° before TDC BOI yielded the lowest average peak packet temperatures (about 1720 K) compared with the 20���° before TDC BOI (about 2480 K) and 40���° before TDC BOI (about 2700 K). These trends support experimental NO x trends, which showed the lowest NO x emissions for the 60���°, 20���°, and 40���° before TDC BOIs in that order. Parametric studies showed that increasing the intake charge temperature, pilot quantity, and natural-gas equivalence ratio all led to higher peak heat release rates and hotter packets but the pilot quantity and intake temperature affected the potential for NO x formation to a greater extent.

IGNITION IMPROVEMENT OF LEAN NATURAL GAS MIXTURES  

SciTech Connect

This report describes work performed during a thirty month project which involves the production of dimethyl ether (DME) on-site for use as an ignition-improving additive in a compression-ignition natural gas engine. A single cylinder spark ignition engine was converted to compression ignition operation. The engine was then fully instrumented with a cylinder pressure transducer, crank shaft position sensor, airflow meter, natural gas mass flow sensor, and an exhaust temperature sensor. Finally, the engine was interfaced with a control system for pilot injection of DME. The engine testing is currently in progress. In addition, a one-pass process to form DME from natural gas was simulated with chemical processing software. Natural gas is reformed to synthesis gas (a mixture of hydrogen and carbon monoxide), converted into methanol, and finally to DME in three steps. Of additional benefit to the internal combustion engine, the offgas from the pilot process can be mixed with the main natural gas charge and is expected to improve engine performance. Furthermore, a one-pass pilot facility was constructed to produce 3.7 liters/hour (0.98 gallons/hour) DME from methanol in order to characterize the effluent DME solution and determine suitability for engine use. Successful production of DME led to an economic estimate of completing a full natural gas-to-DME pilot process. Additional experimental work in constructing a synthesis gas to methanol reactor is in progress. The overall recommendation from this work is that natural gas to DME is not a suitable pathway to improved natural gas engine performance. The major reasons are difficulties in handling DME for pilot injection and the large capital costs associated with DME production from natural gas.

Chapter 9 - Natural Gas Dehydration  

Science Journals Connector (OSTI)

Natural, associated, or tail gas usually contains water, in liquid and/or vapor form, at source and/or as a result of sweetening with an aqueous solution. Operating experience and thorough engineering have proved that it is necessary to reduce and control the water content of gas to ensure safe processing and transmission. Pipeline drips installed near wellheads and at strategic locations along gathering and trunk lines will eliminate most of the free water lifted from the wells in the gas stream. Multistage separators can also be deployed to ensure the reduction of free water that may be present. However, the removal of the water vapor that exists in solution in natural gas requires a more complex treatment. This treatment consists of “dehydrating” the natural gas, which is accomplished by lowering the dew point temperature of the gas at which water vapor will condense from the gas. There are several methods of dehydrating natural gas. The most common of these are liquid desiccant (glycol) dehydration, solid desiccant dehydration, and cooling the gas. Any of these methods may be used to dry gas to a specific water content. Usually, the combination of the water content specification, initial water content, process character, operational nature, and economic factors determine the dehydration method to be utilized. However, the choice of dehydration method is usually between glycol and solid desiccants. These are presented in depth in subsequent portions of this chapter. Keywords: absorber, adsorption isotherm, bed loading, chemisorption, dehydration, desiccant, desiccant regeneration, equilibrium zone, flash tank, flow distribution, glycol circulation pump, glycol dehydration, inlet feed contamination, liquid carryover, mass transfer zone, molecular sieve, overcirculation, reboiler, solubility, still, surge tank, undercirculation.

Natural Gas - CNG & LNG  

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

Natural Gas Natural Gas Natural gas pump Natural gas, a fossil fuel comprised mostly of methane, is one of the cleanest burning alternative fuels. It can be used in the form of compressed natural gas (CNG) or liquefied natural gas (LNG) to fuel cars and trucks. Dedicated natural gas vehicles are designed to run on natural gas only, while dual-fuel or bi-fuel vehicles can also run on gasoline or diesel. Dual-fuel vehicles allow users to take advantage of the wide-spread availability of gasoline or diesel but use a cleaner, more economical alternative when natural gas is available. Since natural gas is stored in high-pressure fuel tanks, dual-fuel vehicles require two separate fueling systems, which take up passenger/cargo space. Natural gas vehicles are not available on a large scale in the U.S.-only

14, 2007 (next release 2:00 p.m. on June 21, 2007) 14, 2007 (next release 2:00 p.m. on June 21, 2007) Natural gas spot and futures prices decreased this week (Wednesday-Wednesday, June 6-13) as weather-related demand was limited amid close-to-normal temperatures for this time of year. Easing prices also likely resulted in part from reduced supply uncertainty in response to the amount of natural gas in underground storage (mostly for use during the winter heating season but also available for periods of hot weather in the summer). Supplies from international sources have grown considerably this spring, as imports of liquefied natural gas (LNG) have increased markedly even as natural gas supplies from Canada (transported by pipeline) likely have decreased. On the week, the Henry Hub spot price decreased 23 cents per MMBtu, or 2.9 percent, to $7.60. At the New York Mercantile Exchange (NYMEX), the contract for July delivery decreased 47.2 cents per MMBtu on the week to a daily settlement of $7.608 yesterday (June 13). EIA's Weekly Natural Gas Storage Report today reported natural gas storage supplies of 2,255 Bcf as of Friday, June 8, reflecting an implied net injection of 92 Bcf. This level of working gas in underground storage is 19.3 percent above the 5-year average inventory for this time of year. The spot price for West Texas Intermediate (WTI) crude oil increased $0.20 per barrel on the week to $66.17 per barrel, or $11.41 per MMBtu.

Natural gas cavern storage regulation  

SciTech Connect

Investigation of an incident at an LPG storage facility in Texas by U.S. Department of Transportation resulted in recommendation that state regulation of natural gas cavern storage might be improved. Interstate Oil & Gas Compact Commission has established a subcommittee to analyze the benefits and risks associated with natural gas cavern storage, and to draft a regulation model which will suggest engineering and performance specifications. The resulting analysis and regulatory language will be reviewed by I.O.G.C.C., and if approved, distributed to member states (including New York) for consideration. Should the states desire assistance in modifying the language to reflect local variables, such as policy and geology, I.O.G.C.C. may offer assistance. The proposed presentation will review the I.O.G.C.C. product (if published at that date), and discuss implications of its application in New York.

For the week (Wednesday to Wednesday), the price at the Henry Hub increased $0.32 per MMBtu, or about 5 percent, to $7.11 per MMBtu. The NYMEX futures contract for November delivery at the Henry Hub rose 45 cents since last Wednesday to close yesterday at $7.458 per MMBtu. Natural gas in storage as of Friday, October 12, was 3,375 Bcf, which is 6.7 percent above the 5-year average. Despite the seemingly favorable supply conditions and little weather-related natural gas demand, natural gas prices continued their upward movement of the past 6 weeks. The Henry Hub spot price exceeded the $7-per MMBtu mark in this week's trading for the first time in 2 months. One factor in the recent run-up in prices may be the relatively low imports of liquefied natural gas (LNG) to the Lower 48 States. LNG imports have averaged less than 1 Bcf per day during the first half of October, based on the sendout data published on companies' websites. LNG cargoes instead are heading to Europe and Asia, where buyers continue to purchase LNG at much higher prices than have prevailed in U.S. markets. A likely influence on natural gas prices is the spot price for West Texas Intermediate (WTI) crude oil, which reached yet another record high on Tuesday, but decreased slightly during yesterday's trading to $87.19 per barrel or $15.03 per MMBtu. On the week, however, the WTI increased $5.89 per barrel or about 7 percent.

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

Intrastate Natural Gas Pipeline Segment Intrastate Natural Gas Pipeline Segment About U.S. Natural Gas Pipelines - Transporting Natural Gas based on data through 2007/2008 with selected updates Intrastate Natural Gas Pipeline Segment Overview Intrastate natural gas pipelines operate within State borders and link natural gas producers to local markets and to the interstate pipeline network. Approximately 29 percent of the total miles of natural gas pipeline in the U.S. are intrastate pipelines. Although an intrastate pipeline system is defined as one that operates totally within a State, an intrastate pipeline company may have operations in more than one State. As long as these operations are separate, that is, they do not physically interconnect, they are considered intrastate, and are not jurisdictional to the Federal Energy Regulatory Commission (FERC). More than 90 intrastate natural gas pipelines operate in the lower-48 States.

Natural Gas Weekly Update  

Gasoline and Diesel Fuel Update (EIA)

Overview Overview Lower prices and a report of another considerable net injection to stocks were featured in last week's gas markets. As of Friday, May 11, 2001, the spot price of natural gas at the Henry Hub dropped $0.24 from the previous Friday to $4.25 per MMBtu. The NYMEX price of natural gas for June delivery at the Henry Hub declined $0.212 for the week to $4.278 per MMBtu. A record-setting 108 Bcf was added to natural gas stocks for the week ended May 4, 2001. The demand for cooling is still somewhat limited as mild temperatures prevailed around most of the country. (See Temperature Map) (See Deviation from Normal Temperatures Map) Prices Mid-week prices were at the lowest level since early August. Even with an end-of-the-week influence from the futures market that caused a slight upturn, spot prices at the major supply hubs were $0.25 to $0.65 cents per MMBtu lower on a week-to-week basis with Katy, Texas ending at $4.23; the Henry Hub, Louisiana at $4.25; Midcon, Oklahoma at $4.11; and Opal, Wyoming at $3.30. Prices at the Chicago and New York citygates were lower as well, registering $4.35 and $4.65 at week's end, off a respective $0.27 and $0.20 per MMBtu for the week. SoCal provided the only exception to the generally lower trend as demand increased because of warmer temperatures. Natural gas prices receded before temperatures did, though. The effect of unscheduled maintenance on the PG&E Gas Transmission system was imperceptible to PG&E's large-volume purchasers. By Friday, the PG&E customers were paying $3.51 less at $4.18 while SoCal's citygate price was only $0.47 lower at $11.92.

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

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

2, 2007 (next release 2:00 p.m. on August 9, 2007) 2, 2007 (next release 2:00 p.m. on August 9, 2007) Natural gas spot prices increased this week (Wednesday-Wednesday, July 25-August 1) as tropical storm activity increased and weather-related demand returned along with normal summertime heat in large market areas in the East. On the week, the Henry Hub spot price increased 62 cents per MMBtu, or 11.1 percent, to $6.19. At the New York Mercantile Exchange (NYMEX), the futures contract for August delivery expired last Friday (July 27) at $6.11 per MMBtu. Although the price of the expiring contract in the last couple days of trading rose slightly, the expiration price was still the second lowest of the year (the January 2007 contract expired at $5.838). Taking over as the near-month contract, the September 2007 contract increased in price by $0.29 per MMBtu on the week to $6.352. EIA's Weekly Natural Gas Storage Report today reported natural gas storage supplies of 2,840 Bcf as of Friday, July 27. This level of working gas in underground storage exceeds the maximum level of the previous 5 years. The spot price for West Texas Intermediate (WTI) crude oil increased $0.75 per barrel on the week to $76.49 per barrel.

2, 2003 (next release 2:00 p.m. on June 19) 2, 2003 (next release 2:00 p.m. on June 19) Moderate temperatures across the country except in the Southwest contributed to natural gas spot prices easing 25 to 50 cents per MMBtu since Wednesday, June 4. On the week (Wednesday, June 4-Wednesday, June 11), the Henry Hub spot price dropped 35 cents per MMBtu to $6.06. The NYMEX futures contract for July delivery at the Henry Hub fell about 16 cents per MMBtu to $6.213. Natural gas in storage as of Friday, June 6, increased to 1,324 Bcf, which is 25.2 percent below the 5-year average. The spot price for West Texas Intermediate (WTI) crude oil rose $2.36 per barrel on the week to yesterday's (June 11) closing price of $32.17 per barrel, or $5.55 per MMBtu. Prices: Natural gas spot prices at many market locations in the Lower 48 States have declined for three consecutive trading days from Friday peaks as key market areas in the Midwest and the Eastern seaboard have experienced unseasonably cool weather. Although prices remain elevated, the slackened demand for natural gas for electric generation has contributed to prices generally softening across the board. For the week, the spot price at the Henry Hub dropped about 6 percent to $6.06 per MMBtu, while other pricing points on the Gulf Coast showed slightly greater declines and fell below the $6-mark. The overall easing of prices may reflect also the slightly improving storage picture as injections in 7 of the past 8 weeks have exceeded the 5-year average with a record net addition reported last Thursday. Although the storage refill season started slowly, injections have increased considerably, with at least one major interstate pipeline serving the Northeast, Tennessee Gas Pipeline, announcing restrictions to shippers due to injection nominations exceeding capacity. The spot price at Tennessee Gas Pipeline's Zone 6, which serves major citygates in New York and other Northeastern states, this week fell 47 cents per MMBtu to $6.30. In contrast to the East, prices in the West moved higher early in the week, as maintenance on El Paso Natural Gas in the San Juan Basin restricted deliveries from the region and a heat wave sparked buying at pricing locations in California and New Mexico. The spot price at the Southern California border surged 61 cents per MMBtu on Monday to $5.78, but has since dropped to $5.51, which is a net decline of 51 cents since Wednesday, June 4.

Storage Storage About U.S. Natural Gas Pipelines - Transporting Natural Gas based on data through 2007/2008 with selected updates Underground Natural Gas Storage Overview | Regional Breakdowns Overview Underground natural gas storage provides pipelines, local distribution companies, producers, and pipeline shippers with an inventory management tool, seasonal supply backup, and access to natural gas needed to avoid imbalances between receipts and deliveries on a pipeline network. There are three principal types of underground storage sites used in the United States today. They are: · depleted natural gas or oil fields (326), · aquifers (43), or · salt caverns (31). In a few cases mine caverns have been used. Most underground storage facilities, 82 percent at the beginning of 2008, were created from reservoirs located in depleted natural gas production fields that were relatively easy to convert to storage service, and that were often close to consumption centers and existing natural gas pipeline systems.

Prices at many major spot markets moved down most days last week and ended the week between 20 and 30 cents per MMBtu below Tuesday's prices. On the NYMEX futures market, the near-month (July) contract also ended the week down 25 cents from Tuesday's high of $3.981. Much of the country continued to enjoy moderate temperatures during last week, which saw the first day of summer (June 21) prices (See Temperature Map) (See Deviation from Normal Temperatures Map).

Natural Gas Weekly Update  

Gasoline and Diesel Fuel Update (EIA)

Holiday Notice: Holiday Notice: Due to the federal holiday in observance of Martin Luther King Day on Monday, January 21, 2002, the next issue of the Natural Gas Weekly Update will be published on Tuesday, January 22, 2002. Overview: Monday, January 14, 2002 Natural gas prices were generally lower last week as the fundamentals of ample working gas in storage and very little temperature-driven swing demand dominated the market. With little in the way of market-changing developments, trading in both the spot and futures markets tended to occur in relatively small price ranges throughout the week. The warming trend begun late in the previous week continued nearly unabated through last week, with the heavy gas-consuming areas of the Midwest and Northeast recording many of the greatest deviations above daily normal temperatures. Philadelphia, New York City, and Buffalo, NY had at least 3 days of temperatures that were 10 or more degrees above normal; Chicago's temperature reached an unusually warm 26 degrees above normal on Wednesday. (See Temperature Map) (See Deviation Map) Spot prices at the Henry Hub moved down moderately from the previous week, ending trading on Friday at $2.31, down 5 cents from the previous Friday. On the NYMEX, the futures contract for February delivery at the Henry Hub declined by $0.071 from the previous Friday, settling on Friday, January 11 at $2.204 per MMBtu. The spot price for West Texas Intermediate crude oil also fell, dipping below $20 per barrel for the first time in the New Year, ending trading last Friday at $19.67 per barrel, or $3.39 per MMBtu, down $1.80 per barrel, or $0.31 per MMBtu, from Friday, January 4.

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

Investigation on characteristics of ionization current in a spark-ignition engine fueled with natural gas–hydrogen blends with BSS de-noising method  

Science Journals Connector (OSTI)

Investigation on ionization current characteristic in a spark-ignition engine fueled with natural gas, natural gas–hydrogen bends and gasoline was conducted. Blind Source Separation (BSS) de-noising method is employed to separate the ionization current signal from the interference of spark tail generated by ignition discharge. Cylinder pressure was recorded, and local temperature at spark plug gap is calculated using AVL-FIRE simulation code. Results show that the simulated cylinder pressures are in good agreement with those of measured and the spark tail and ionization current can be separated using BSS method. Front flame stage and post flame stage in ionization current can be used to analyze the combustion characteristics of natural gas–hydrogen blends. De-noised current shows that the appearance of front flame stage and post flame stage (including the peaks in the stages) fueled with natural gas is postponed and compared with that fueled with gasoline, and the appearance of front flame stage and post flame stage advance with the increase of hydrogen fraction in natural gas–hydrogen blends. In addition, the amplitude of ionization currents in both front flame and post flame (including the two peaks) fueled with natural gas gives lower values compared with those fueled with gasoline and hydrogen addition can increase the amplitude. Maximum post flame current shows similar trend to maximum cylinder pressure and it has good correlation between the timing of maximum post flame current and the timing of maximum cylinder pressure. High correlation coefficient between maximum post flame current and maximum pressure is presented.

9, 2007 (next release 2:00 p.m. on July 26, 2007) 9, 2007 (next release 2:00 p.m. on July 26, 2007) Since Wednesday, July 11, natural gas spot prices decreased at virtually all markets in the Lower 48 States. Prices at the Henry Hub declined 41 cents per MMBtu, or 6 percent, since Wednesday, July 11, to $6.24 per MMBtu. At the NYMEX, the futures contract for August delivery at the Henry Hub settled yesterday (July 18) at $6.528 per MMBtu, falling 7 cents per MMBtu, or 1 percent since last Wednesday, July 11. Natural gas in storage was 2,692 Bcf as of July 13, which is 15.7 percent above the 5-year average (2002-2006). The spot price for West Texas Intermediate (WTI) crude oil gained $2.45 per barrel on the week (Wednesday-Wednesday) to $75.03 per barrel or $12.94 per MMBtu. Prices: Natural gas prices fell at virtually all market locations since last Wednesday, July 11, with declines of 25 to 50 cents per MMBtu or about 4 to 12 percent. Moderating temperatures in most areas of the Lower 48 States likely accounted for the widespread declines, as cooler temperatures mitigated cooling demand for natural gas. On a regional basis, price declines averaged between 18 and 58 cents per MMBtu, or 3 and 13 percent, since last Wednesday, July 11. The largest price decreases since last Wednesday, July 11, occurred principally in the Rocky Mountain region, where prices fell by more than 57 cents per MMBtu, or 13 percent on average. By far, the smallest decreases occurred in the Arizona/Nevada and Florida regions, where prices fell by 18 and 24 cents per MMBtu on average, respectively, with the Florida citygate posting the highest price in the Lower 48 States at $8.00 per MMBtu. Elsewhere, average price decreases by region ranged between 30 and 43 cents per MMBtu. Despite these declines and lower electric generation demand relative to last year, prices generally exceeded levels reported last year at this time, with prices at the Henry Hub $0.22 per MMBtu or 4 percent above last year's level. The principal exception to the year-over-year price increases occurred in the Rocky Mountain region, where prices at selected markets were between $1.87 and $2.28 per MMBtu or about 35 and 43 percent below last year's level.
