    2017-03-01

    LNG progressively become favorable energy to replace oil-based fuel due to lower cost and more environment-friendly. In order to support an emerging LNG demands in Kalimantan, PT Badak NGL, one of the leading LNG Company in the world, develops the land-transported LNG loading facility. This facility performs loading the LNG into a small-scale tank (ISO Tank) with 20 m3 capacities. Safety reviews over this facility were conducted. Based on these reviews, the LNG filling station requires supplemental safeguards, such as LNG spill containment and firefighting foam system besides firewater system and dry chemical system. The spill containment provides holding LNG spill within the limits of plant property, while the high expansion foam system deals to minimize the vaporization rate to prevent a fire incident. This paper mainly discusses designing of such supplemental safeguards. The requirement of the spill containment is 20 m3 (6.3 × 3.3 × 2.0) m and the foam system should be capable generating foam at least 40 m3/min.

    LNG storage facilities are indispensable to satisfy demand throughout the year by saturating the time difference of supply and demand that appears due to seasonal factors. The necessity of storage facilities is more important in a country like Korea where LNG is not produced at all and imports are relied upon. The problem of deciding how much storage facilities to keep and in what pattern to import LNG is a question to solve in order to minimize the costs related to the construction of LNG storage facilities while not causing any problem in the supply and demand of LNG. This study analyzes how the import of LNG and the consumption pattern of LNG for power generation affect the decision on the size of storage facilities. How the shipping control, and how LNG demand for power generation affect the decision of requirement of storage facilities, and why the possibility of shipping control should be investigated in the aspect of costs is investigated. As a result of this study, I presented necessary basic data for drafting a policy by assessing the minimum requirements of storage facilities needed for balancing the supply and demand with the various shipping control and LNG consumption patterns through simulation up to the year 2010. 10 refs., 33 figs., 66 tabs.

    Germany needs an LNG receiving terminal to import LNG and supplement expected future gas supply shortages. Enormous economic benefits also abound if Germany is to install an LNG receiving terminal. Jobs will be created for several hundred people. New tax revenues will be generated for state and local governments and this will further enhance the economic competitiveness of Germany. Additionally, it will provide Germany with a reliable source of clean-burning energy. Any proposed LNG receiving terminal should incorporate safety right from the start. These safety requirements will: ensure that certain public land uses, people, and structures outside the LNG facility boundaries are protected in the event of LNG fire, prevent vapour clouds associated with an LNG spill from reaching a property line that can be built upon, prevent severe burns resulting from thermal radiation, specify requirements for design, construction and use of LNG facilities and other equipments, and promote safe, secure and reliable LNG operations. The German future LNG business will not be complete without the evolution of both local and international standards that can apply to LNG operations. Currently existing European standards also appear inadequate. With an OHSAS 18001 management system integrated with other existing standards we can better control our LNG occupational health and safety risks, and improve performance in the process. Additionally, an OHSAS 18001 System will help future German LNG contractors and operators safeguard their most important assets - their employees. (orig.)

    The design, engineering and operation of LNG base load liquefaction and re-gasification facilities is now considered a mature technology. However, process efficiency at these plants is limited by fundamental thermodynamic principles and no radical technology breakthroughs are expected in the near future. Three important aspects affecting the cost of production are the molecular weight of the gas, the amount of nitrogen in the feed and the acid gas composition. Variations in composition will also affect the design of the facilities and production rate. Previous projects have optimised economies of scale, using processes based on large industrial gas turbines, to achieve the minimum unit cost for LNG production. LNG producers have continued to focus on larger train designs to further capitalize on economies of scale as well as continued expansion of existing facilities. The latest plant designs expect the optimum integration with existing facilities to be a major factor in optimising specific capital costs. Whilst design codes and standards have not been discussed in many papers on LNG cost reduction, it is generally accepted that project specifications can significantly impact the project cost. The cost of equipment can be significantly inflated by onerous specifications with non standard requirements that vendors have trouble meeting. The possibility of developing gas projects will mainly be determined by the requirements of power generation and/or the industrial sector. As far as power generation is concerned, expansion will rely greatly on combined cycle plants. The competitiveness of LNG as regards power generation can be further improved by adopting integrated solutions. As in all other industrial projects, one of the first concerns for the investor when he envisages building an LNG liquefaction or re-gasification terminal is the selection of the site where the terminal will be located.

    Kitimat LNG terminal is the first fully permitted liquefied natural gas (LNG) on the west coast of Canada and the United States. The terminal was designed to have a small environmental footprint, and has the full support of communities and First Nations groups in the area. Regulatory approvals are now in place, and site construction is planned to start in 2007. This presentation provided details of the facility's gas production and liquefaction processes, shipping, and LNG import and regasification terminals. The site was selected due to its deepwater, all-season port and the fact that the Pacific Trail Pipelines provide access to major transmission lines. The terminal will be comprised of an offshore LNG tanker berth and unloading jetty, a construction and tug berth, 2 LNG storage tanks, a separation unit, and send-out pipelines for natural gas and gas liquids. The terminal was designed for maximum LNG receiving flexibility as it can handle a wide variety of gas specifications and will be able to receive the largest possible LNG tankers. Market interest in the terminal has been considerable as investors are increasingly convinced that LNG can provide long-term supply alternatives to the North American gas market. Once operational the terminal will attract supply from the Pacific basin and the Middle East. Western Canadian gas demand is projected to grow at nearly 6 per cent through 2015. It was concluded that marine safety is crucial to the successful operation of the terminal. Details of safety plans formed after consultation with various organizations were presented. refs., tabs., figs.

    2013-03-01

    In the present paper, the sloshing resistance performance of a huge-size LNG carrier's insulation system is evaluated by the fluid-structure interaction (FSI) analysis. To do this, the global-local analysis which is based on the arbitrary Lagrangian-Eulerian (ALE) method is adopted to accurately calculate the structural behavior induced by internal LNG sloshing of a KC-1 type LNG carrier insulation system. During the global analysis, the sloshing flow and hydrodynamic pressure of internal LNG are analyzed by postulating the flexible insulation system as a rigid body. In addition, during the local analysis, the local hydroelastic response of the LNG carrier insulation system is computed by solving the local hydroelastic model where the entire and flexible insulation system is adopted and the numerical analysis results of the global analysis such as initial and boundary conditions are implemented into the local finite element model. The proposed novel analysis techniques can potentially be used to evaluate the structural integrity of LNG carrier insulation systems.

    This cooperative research project validates use of man made salt caverns to receive and store the cargoes of LNG ships in lieu of large liquid LNG tanks. Salt caverns will not tolerate direct injection of LNG because it is a cryogenic liquid, too cold for contact with salt. This research confirmed the technical processes and the economic benefits of pressuring the LNG up to dense phase, warming it to salt compatible temperatures and then directly injecting the dense phase gas into salt caverns for storage. The use of salt caverns to store natural gas sourced from LNG imports, particularly when located offshore, provides a highly secure, large scale and lower cost import facility as an alternative to tank based LNG import terminals. This design can unload a ship in the same time as unloading at a tank based terminal. The Strategic Petroleum Reserve uses man made salt caverns to securely store large quantities of crude oil. Similarly, this project describes a novel application of salt cavern gas storage technologies used for the first time in conjunction with LNG receiving. The energy industry uses man made salt caverns to store an array of gases and liquids but has never used man made salt caverns directly in the importation of LNG. This project has adapted and expanded the field of salt cavern storage technology and combined it with novel equipment and processes to accommodate LNG importation. The salt cavern based LNG receiving terminal described in the project can be located onshore or offshore, but the focus of the design and cost estimates has been on an offshore location, away from congested channels and ports. The salt cavern based terminal can provide large volumes of gas storage, high deliverability from storage, and is simplified in operation compared to tank based LNG terminals. Phase I of this project included mathematical modeling that proved a salt cavern based receiving terminal could be built at lower capital cost, and would have significantly higher

  9. Comparison between reverse Brayton and Kapitza based LNG boil-off gas reliquefaction system using exergy analysis

    Science.gov (United States)

    Kochunni, Sarun Kumar; Chowdhury, Kanchan

    2017-02-01

    LNG boil-off gas (BOG) reliquefaction systems in LNG carrier ships uses refrigeration devices which are based on reverse Brayton, Claude, Kapitza (modified Claude) or Cascade cycles. Some of these refrigeration devices use nitrogen as the refrigerants and hence nitrogen storage vessels or nitrogen generators needs to be installed in LNG carrier ships which consume space and add weight to the carrier. In the present work, a new configuration based on Kapitza liquefaction cycle which uses BOG itself as working fluid is proposed and has been compared with Reverse Brayton Cycle (RBC) on sizes of heat exchangers and compressor operating parameters. Exergy analysis is done after simulating at steady state with Aspen Hysys 8.6® and the comparison between RBC and Kapitza may help designers to choose reliquefaction system with appropriate process parameters and sizes of equipment. With comparable exergetic efficiency as that of an RBC, a Kaptiza system needs only BOG compressor without any need of nitrogen gas.

    2017-03-01

    As a clean fuel, LNG has been used in heavy vehicles widely in China. Before reaching the engine for combustion, LNG store in a high vacuum multi-layer thermal insulation tank and need to be evaporated from its cryogenic state to natural gas. During the evaporation, the available cold energy of LNG has been calculated. The concept has been proposed that the separated type heat pipe technology is employed to utilize the available cold energy for automotive air-conditioning. The experiment has been conducted to validate the proposal. It is found that it is feasible to use the separated type heat pipe to convey the cold energy from LNG to automotive air-conditioning. And the cooling capacity of the automotive air-conditioning increase with the LNG consumption and air flow rate increasing.

    To enhance the energy efficiency in the liquefied natural gas (LNG) vehicles, thermoelectric generator (TEG) is suggested in recovering the waste heat of the exhaust gas (EG) and the cold energy of the LNG.The TEGs here get higher efficiency than conventional ones, for they work with heat sinks at cryogenic temperatures and there are large temperature differences between EG and LNG.Based on the analyzing of the typical fuel system in the small LNG vehicles, two recovery systems for the LNG vehicles are proposed and the correla_tive parameters of systems are calculated and analyzed.The generation efficiency of TEGs is calculated and the recovery power of each sys_tem is analyzed.It is concluded that the output power of the vaporizer system is larger than that of the self_warming system; TEG with opti_mized multi_layer material brings larger output power than that with single_layer material for both systems.%为实现液化天然气(LNG)汽车的节能,提出了利用温差发电器(TEG)回收发动机排气(EG)的废热和低温燃料的冷能。指出了基于冷源所在的低温区,以及 EG 与 LNG 之间的大温差这两个特点,TEG 的热电转换效率会高于常规。基于对小型 LNG汽车中典型燃料系统的分析,设计了进行能量回收的两种系统流程,计算了其中各状态点的参数﹑及各换热器中布置温差发电器后的热电转换效率,得到了系统总的回收功率。结果表明,汽化器系统的回收功率大于自复温系统;在两种系统中,合理选取多种材料相较于仅用单种材料,TEG 的回收功率更大。

    Onshore LNG receiving terminal is an important facility in offshore LNG import system. According to the growing human accidents of LNG receiving terminals in China at present, based on the HFACS analysis of accident causation model which had been used in the aviation accident investigation, the impact factors of human accidents were divided into five categories, which contain personal factors, group factors, environmental factors, supervision and organizational factors, and the human accidents identification method of LNG receiving terminal was obtained based on grey relational analysis of gray theory. Finally, the method was applied to identify the accidents happened in an LNG receiving terminal, and it was found that the main insecurity events were "the una-wareness of security" in "personal factors" by calculating the grey relational grade. This method overcomes the disadvantage due to the small sample of accident data, which has certain guiding sense to safeguard the safety operation of LNG receiving terminals.%陆岸LNG接收终端是LNG海上进口系统中的重要设施.针对我国LNG接收终端人因事故不断增多的现状,基于航空事故调查分析中的HFACS事故致因分析模型,将人因事故的影响因素归纳为个人因素、人际因素、环境因素、监督因素和组织因素五大类,结合灰色理论中的灰色关联分析,得到了LNG接收终端人因事故辨识方法.最后,运用该方法对某LNG接收终端人因事故进行辨识,通过灰关联度的计算,找出其最主要的不安全事件来自“个人因素”中的个人“安全意识不强”.此方法克服了小样本事故数据带来的弊端,对保障LNG接收终端的安全运行具有一定的指导意义.

    @@ China National Petroleum Corporation (CNPC) broke ground in mid-April for the construction of its first liquefied natural gas (LNG) terminal in Dalian, a port city in northeastern Liaoning Province. This project,with a total investment of over 10 billion yuan (about $1.4 billion), consists of a wharf, a receiving facility and transportation pipelines. It is designed to receive supplies from Qatar, Australia and other overseas markets. CNPC is also building a LNG receiving facility in Rudong county of Eastern China's Jiangsu Province. Experts predicted that by 2020 China would import 10 million tons of LNG annually, stimulating the interests of oil giants to build LNG projects.

    The conversion potential to replace oil in the energy intensive industries and diesel in heavy transport is estimated in the study to 6.8 TWh and 10 TWh per year, respectively. Several alternative fuels compete for this conversion potential. What fuels will take market share depends on several factors such as price, availability of fuel, availability of process technology and vehicles, technology development and possible future technological advances. For liquid methane to compete a new infrastructure is required that in a cost effective manner makes it possible to distribute the liquid methane to the regions where the need is the greatest. With today's distribution system, including truck delivery from import terminals in Nynaeshamn and Fredrikstad, virtually the entire southern Sweden is within reach of LNG deliveries. The study points out three nodes, Gaevle, Sundsvall and Luleaa, which is suitable for distribution of liquid methane to the central and northern Sweden. The three hubs are suitable for freight transfer to trucks as well as rail and shipping. A strategic nationwide network of refueling stations is also proposed, with a total of 18 new stations, in addition to the filling stations in southern and central Sweden that are already planned or in operation. Both the availability and use of liquid methane in Sweden today is limited. Liquid natural gas, LNG (liquefied natural gas), is primarily used as a backup to biogas plants, in a few industries and as supply for a few filling stations for compressed gas. The availability of LNG and also liquid biogas (LBG liquefied biogas), will increase in coming years. In 2011, two new LNG import terminals are put into operation in Nynaeshamn and Fredrikstad in Norway and two additional import terminals are planned in Gothenburg and Lysekil. Furthermore, two production plants for liquid biogas production have started, and four additional plants are planned, which together will produce around 0.5 TWh LBG annually

    The US Department of Energy (DOE) is conducting research on the safety and other environmental aspects of liquefied energy gases including liquefied natural gas (LNG). The effort reported here was conducted as part of the planning for further research into the safety aspects of transporting and storing LNG, with primary emphasis on public safety. Although the modern LNG industry has enjoyed excellent success in providing for safe operations, significant questions remain on the part of many, the expressions of which were intensified with the addition of marine-based LNG import terminals. Public safety with regard to large-scale importation of this fuel has received widespread attention in the US Congress, state legislatures, county and city governments, and from various individuals and public groups, with coverage in all the news media, including books published on the subject. The safety concerns have centered around the consequences to the public of a large spill of the cryogenic liquid from an ocean tanker or a larger storage tank, either of which might hold as much as 125,000 m/sup 3/ of LNG.

    2005-05-31

    This cooperative research project validates use of man made salt caverns to receive and store the cargoes of LNG ships in lieu of large liquid LNG tanks. Salt caverns will not tolerate direct injection of LNG because it is a cryogenic liquid, too cold for contact with salt. This research confirmed the technical processes and the economic benefits of pressuring the LNG up to dense phase, warming it to salt compatible temperatures and then directly injecting the dense phase gas into salt caverns for storage. The use of salt caverns to store natural gas sourced from LNG imports, particularly when located offshore, provides a highly secure, large scale and lower cost import facility as an alternative to tank based LNG import terminals. This design can unload a ship in the same time as unloading at a tank based terminal. The Strategic Petroleum Reserve uses man made salt caverns to securely store large quantities of crude oil. Similarly, this project describes a novel application of salt cavern gas storage technologies used for the first time in conjunction with LNG receiving. The energy industry uses man made salt caverns to store an array of gases and liquids but has never used man made salt caverns directly in the importation of LNG. This project has adapted and expanded the field of salt cavern storage technology and combined it with novel equipment and processes to accommodate LNG importation. The salt cavern based LNG receiving terminal described in the project can be located onshore or offshore, but the focus of the design and cost estimates has been on an offshore location, away from congested channels and ports. The salt cavern based terminal can provide large volumes of gas storage, high deliverability from storage, and is simplified in operation compared to tank based LNG terminals. Phase I of this project included mathematical modeling that proved a salt cavern based receiving terminal could be built at lower capital cost, and would have significantly higher

    The results of an investigation of human factors engineering and human reliability applications to LNG release prevention and control are reported. The report includes a discussion of possible human error contributions to previous LNG accidents and incidents, and a discussion of generic HF considerations for peakshaving plants. More specific recommendations for improving HF practices at peakshaving plants are offered based on visits to six facilities. The HF aspects of the recently promulgated DOT regulations are reviewed, and recommendations are made concerning how these regulations can be implemented utilizing standard HF practices. Finally, the integration of HF considerations into overall system safety is illustrated by a presentation of human error probabilities applicable to LNG operations and by an expanded fault tree analysis which explicitly recognizes man-machine interfaces.

    Science.gov (United States)

    Roszak, E. A.; Chorowski, M.

    2014-01-01

    This article gives an overview on new exergy recovery methods for LNG. The concept is based on coupling the LNG regasification unit with the filling process of Adsorbed Natural Gas (ANG) tanks. The latent heat of the LNG vaporization is directly used for precooling the ANG adsorption bed. This reduces the back pressure from filling ANG tanks due to strong adsorption temperature dependency. This improves the economic attractiveness of ANG storage (no need for compressors, longer lifetime cycle of adsorbent). This case study presents the concept of LNG - ANG coupling. Presented results are based on experimental adsorption data. A brief exergy analysis of the process shows an advantage of this method over others. This LNG-ANG method is worth consideration as a cost optimizing solution, especially for periodically working regasification stations.

    @@ Liquefied Natural Gas (LNG) is a low-temperature liquid mixture (-162℃) obtained by cooling and liquefaction of natural gas after deacidification and dehydration. In recent years, along with the surging global demand for energy and the drop of LNG cost, demand for LNG has been rising steadily. The primary underlying causes of that are the reduction of cost, the improvement of ship transportation and the changes in the form of trade. The tightening energy bottleneck brought by the rapid growth of China's economy might be well addressed by the active development of LNG industry, which can also help diversify the energy resources and facilitate the protection of environment.

    The floating production, storage and offload-ing system for liquefied natural gas (LNG-FPSO), is a new conceptual unit and an effective and realistic way for exploitation, recovery, storage, transportation and end-use applications of marginal gas fields and offshore associated-gas resources. However, a real LNG-FPSO unit cannot be built unless some breakthroughs in many key technologies are produced. Many unique characteris-tics of LNG-FPSO, such as restricted space, platform motion, LNG sloshing in inner storage tank and offload-ing system, which have not been considered in the onshore projects, are the most rigorous factors to be taken into account during design. In this paper, the overall layout of a typical LNG-FPSO unit is reviewed; the leading liquefaction technologies and processes are compared and discussed. Taking the effects of the vessel motion and limited space into account, the applicability of the main systems and key equipments of storage, offloading and power supply, are analyzed.

    The procedure of reliability-based fatigue analysis of liquefied natural gas (LNG) carrier of membrane type under wave loads is presented. The stress responses of the hotspots in regular waves with different wave heading angles and wave lengths are evaluated by global ship finite element method (FEM). Based on the probabilistic distribution function of hotspots' short-term stress-range using spectral-based analysis, Weibull distribution is adopted and discussed for fitting the long-term probabilistic distribution of stress-range. Based on linear cumulative damage theory, fatigue damage is characterized by an S-N relationship, and limit state function is established. Structural fatigue damage behavior of several typical hotspots of LNG middle ship section is clarified and reliability analysis is performed. It is believed that the presented results and conclusions can be of use in calibration for practical design and initial fatigue safety evaluation for membrane type LNG carrier.

    The liquefied natural gas (LNG) industry employs a variety of release prevention and control techniques to reduce the likelihood and the consequences of accidental LNG releases. A study of the effectiveness of these release prevention and control systems is being performed. Reference descriptions for the basic types of LNG facilities were developed. Then an overview study was performed to identify areas that merit subsequent and more detailed analyses. The specific objectives were to characterize the LNG facilities of interest and their release prevention and control systems, identify possible weak links and research needs, and provide an analytical framework for subsequent detailed analyses. The LNG facilities analyzed include a reference export terminal, marine vessel, import terminal, peakshaving facility, truck tanker, and satellite facility. A reference description for these facilities, a preliminary hazards analysis (PHA), and a list of representative release scenarios are included. The reference facility descriptions outline basic process flows, plant layouts, and safety features. The PHA identifies the important release prevention operations. Representative release scenarios provide a format for discussing potential initiating events, effects of the release prevention and control systems, information needs, and potential design changes. These scenarios range from relatively frequent but low consequence releases to unlikely but large releases and are the principal basis for the next stage of analysis.

    Naeslund, M.

    2012-05-15

    The interest for LNG both on a small and a large scale is increasing worldwide. The experiences and knowledge on LNG is limited in Denmark. The Danish gas companies' Technical Management Group (TCG) has asked for a status report including a technology description and an evaluation of the potential in Denmark. A survey of primarily small-scale LNG technology is done in the report. The focus is motivated by the new areas of gas utilisation that become possible with small-scale LNG. Small-scale LNG in this study is defined as LNG stored and used at the application or in an isolated gas grid. The small-scale use of LNG has today an almost negligible share of the total LNG trade but offers interesting new applications for gas utilisation. LNG on a small scale can be used primarily as: 1) Ship fuel. 2) Truck fuel (heavy duty long distance). 3) Individual users not connected to the natural gas grid. 4) Backup for upgraded biogas to individual users and vehicle fleets. 5) Security of supply or supply enhancement of heavily loaded parts of the gas grid. 6) Small-scale storage and/or peak shaving. All but the first topics are natural uses for the current Danish gas distributors. LNG as ship fuel may engage other specialized LNG companies. The report contains a technical description of the parts in primarily small-scale LNG handling and operation. Liquefaction, transport, storage, engine technologies, gas quality and safety aspects related to LNG are covered. There seem to be two more or less separate paths for LNG in Denmark, onshore and off-shore use. These are not, apparently, sharing their experiences and knowledge. Rules and regulations are also different which may create some problems in the interface, for example ship bunkering. Further studies are suggested in the area of gas quality and engine technologies and adaptation of foreign guidelines for small-scale installations to Danish conditions. These guidelines ought to be based on international standards and

    Matija Veselić

    2011-12-01

    Full Text Available Increasing natural gas consumption, declining North Sea gas reserves, increased production costs and the deregulation of European gas and electricity markets have all combined to create new opportunities for LNG in Europe. In these circumstances, LNG represents an opportunity for many European countries to diversify their natural gas supply, while decreasing their dependence on Russian natural gas import at the same time. The largest exporters of LNG to Europe are Qatar, Algeria, Nigeria, Trinidad & Tobago, Egypt and Oman. Spain, Great Britain and France are the largest European importers of LNG. Spain has six LNG regasification terminals, followed by four in Great Britain, three in France, two in Italy and Turkey and finally Greece and Portugal with one terminal each. New LNG regasification terminals are currently under construction in Italy, Spain, Sweden and Netherlands. In addition, more than 30 new LNG terminal projects have been proposed around Europe. Italy plans to construct as many as 10 new regasification terminals, due to the strong orientation of its national energy policy towards LNG. Many European countries are strongly considering participating in the LNG chain for the first time, namely Albania, Cyprus, Ireland, Lithuania, Germany, Poland, Romania, Ukraine and Croatia. This paper focuses on a specific aspect of the LNG supply chain: the import facility (the paper is published in Croatian.

The stripped gas is reinjected for pressure maintenance operations. With the completion of the LNG program full use of the gas will be achieved. It will totally meet the needs of combustible liquids for the central and northern parts of the country, a volume of 2200 million cu m/yr. For its treatment natural gas is sent through gas pipelines to the LNG plant at Cabo Negro. By means of a cooling process, the gas is cooled to -160 C where it becomes a liquid and its volume is reduced by a factor of 600. It is then stored in tanks at atmospheric pressure.

    The operation of liquefied natural gas (LNG) is pioneering within the PETROBRAS System. PETROBRAS Transporte - TRANSPETRO is going to operate two flexible LNG terminals, located in Ceara and Rio de Janeiro. In accordance with the Corporate Health, Safety and Environmental (HSE) Directive - Training, Education and Awareness, PETROBRAS Transporte S.A. - TRANSPETRO has prepared an action plan with the objective of ensuring the operational safety of the undertaking. Among other actions a training program for the emergency control of LNG will be inserted into the timetable. The above mentioned training program was held over a period of 20 hours, and was divided between theory and practice. In the theoretical part, the characteristics of the product, the history of accidents and the emergency response procedures were covered. In the practical part, 3000 gallons of LNG were utilized where the behavior of the product could be confirmed following a confined leak, thereby verifying the efficacy of the emergency control resources. The teaching process of the course was developed in the company through the preparation of specific procedures, emergency plans and the formation of internal instructors. (author)

    The increasing demand for natural gas could increase the number and frequency of Liquefied Natural Gas (LNG) tanker deliveries to ports across the United States. Because of the increasing number of shipments and the number of possible new facilities, concerns about the potential safety of the public and property from an accidental, and even more importantly intentional spills, have increased. While improvements have been made over the past decade in assessing hazards from LNG spills, the existing experimental data is much smaller in size and scale than many postulated large accidental and intentional spills. Since the physics and hazards from a fire change with fire size, there are concerns about the adequacy of current hazard prediction techniques for large LNG spills and fires. To address these concerns, Congress funded the Department of Energy (DOE) in 2008 to conduct a series of laboratory and large-scale LNG pool fire experiments at Sandia National Laboratories (Sandia) in Albuquerque, New Mexico. This report presents the test data and results of both sets of fire experiments. A series of five reduced-scale (gas burner) tests (yielding 27 sets of data) were conducted in 2007 and 2008 at Sandia's Thermal Test Complex (TTC) to assess flame height to fire diameter ratios as a function of nondimensional heat release rates for extrapolation to large-scale LNG fires. The large-scale LNG pool fire experiments were conducted in a 120 m diameter pond specially designed and constructed in Sandia's Area III large-scale test complex. Two fire tests of LNG spills of 21 and 81 m in diameter were conducted in 2009 to improve the understanding of flame height, smoke production, and burn rate and therefore the physics and hazards of large LNG spills and fires.

    The project's main task was to review logistical, technical and economic feasibility for using Liquefied Natural Gas (LNG) and Compressed Natural Gas (CNG) as fuel for ship propulsion and the supply of LNG or CNG to Danish ports from existing natural gas lines, trucks or by ship. The following key findings are related to the use of natural gas as fuel for ships in Denmark: Natural gas as propulsion fuel in ships: 1) Advantages: Provide solution to present air emission challenges 2) Barriers: Capital investments large 3) Synergies: Developments in Norway and Baltic Sea area 4) Economy: Positive case for operation for large consumers 5) Future: Develop bunkering options for short sea shipping LNG: 6) Propulsion technology in ships is mature and proven 7) Distribution network not yet developed for use in ships 8) Safety concerns are demanding but manageable 9) Can enter existing bunkering value chain CNG: 10) Well developed for land based transport, not yet for shipping 11) Distribution network for natural gas exists in Denmark 12) Safety concerns are demanding but manageable 13) No seaborne CNG value chains in operation An immediate focus on the ferry sector in Denmark will reap benefits on a relatively short time scale. For the short sea shipping sector away to promote the conversion to natural gas is to support the development of storage and bunkering facilities in main ports. Given the general expectations in the shipping community LNG will presumably be the de facto choice at least for the 5-10 years ahead and the demand for facilities and bunkers will be for LNG. (LN)

  16. Steady-state and dynamic simulation study on boil-off gas minimization and recovery strategies at LNG exporting terminals

    Science.gov (United States)

    Kurle, Yogesh

    Liquefied natural gas (LNG) is becoming one of the prominent clean energy sources with its abundance, high calorific value, low emission, and price. Vapors generated from LNG due to heat leak are called boil-off gas (BOG). As world-wide LNG productions are increasing fast, BOG generation and handling problems are becoming more critical. Also, due to stringent environmental regulations, flaring of BOG is not a viable option. In this study, typical Propane-and-Mixed-Refrigerant (C3-MR) process, storage facilities, and loading facilities are modeled and simulated to study BOG generation at LNG exporting terminals, including LNG processing, storage, and berth loading areas. Factors causing BOG are presented, and quantities of BOG generated due to each factor at each location are calculated under different LNG temperatures. Various strategies to minimize, recover, and reuse BOG are also studied for their feasibility and energy requirements. Rate of BOG generation during LNG loading---Jetty BOG (JBOG)---changes significantly with loading time. In this study, LNG vessel loading is simulated using dynamic process simulation software to obtain JBOG generation profile and to study JBOG recovery strategies. Also, fuel requirements for LNG plant to run steam-turbine driven compressors and gas-turbine driven compressors are calculated. Handling of JBOG generated from multiple loadings is also considered. The study would help proper handling of BOG problems in terms of minimizing flaring at LNG exporting terminals, and thus reducing waste, saving energy, and protecting surrounding environments.

    A study was conducted to investigate the environmental aspects, and to a lesser extent economic aspects, of using LNG (Liquefied Natural Gas) as a fuel for different types of ships. The study was supported by the Dutch Maritime Innovation Programme (MIP) and 12 industrial stakeholders. The investigation was carried out as a case study for three different types of ships which have their base in Rotterdam, the Netherlands. The three evaluated cases are: (1) a short sea ship: an 800 TEU container feeder; (2) a port ship: an 80 ton harbour tug; (3) a 110 x 11.5 m inland ship. The environmental aspects include greenhouse gas (GHG) and air pollutant emissions. The GHG emission comparison included three LNG chains and three diesel fuel chains (HFO (Heavy Fuel Oil), MDO/MGO (Marine Diesel Oil / Marine Gas Oil) and EN590 (automotive diesel fuel type)). In addition a limited economic analysis was done, comparing the potential fuel cost savings of LNG with the additional costs of LNG powered vessels. The LNG chains considered are: LNG from Peakshaver Rotterdam: Pipeline gas from the North Sea; LNG supplied by LNG carrier from the Middle East (Qatar); LNG from Peakshaver Rotterdam: Pipeline gas from Russia (7000 km). The last chain is not a realistic option for direct LNG supply to Rotterdam and is merely added for reference.

    comes to the purchase costs and the railroad and large-scale sea transport costs. It is also worth noticing that the cost estimation models used in this study sometimes contain large steps for the different cost situations. This is the case for small-scale/base-load ships, purchase cost for Norwegian/Algerian LNG and wagon transport/system trains. The results are hence sometimes less accurate. As a side assignment, the costs for peak-shaving by the use of LNG is looked into. 20-30 MW for 24 hours per year need to be cut at Oeresundskraft's combined power and heat plant in Helsingborg. Here, the possibility of utilising portable LNG containers (as used by the Norwegian company Liquiline) is studied. In order to indicate the extent to which some key parameters affect the final cost, sensitivity analysis is carried out on the purchase price and the terminal costs. The results show that the Norwegian LNG costs 560-608 SEK/MWh (road), 570-689 SEK/MWh (railroad) and 537-555 SEK/MWh (sea). Algerian LNG costs 315-324 SEK/MWh (sea). The large difference between Norwegian and Algerian LNG is caused primarily by the much lower purchase costs of Algerian LNG, and also due to the difference in sea shipping costs. The purchase cost is about 80 % of the total cost for all cases. The transport cost is between 3 and 6 % and the terminal costs the balance, making it a larger component in the cases of Algerian than Norwegian LNG. It is shown that LNG could be an alternative to secure the Natural Gas supply after the Danish supply has run out. It has proven safe and the market is getting more and more mature. The fate of base-load LNG is largely determined by the other Natural Gas projects in the Nordic countries. The Natural Gas market price largely follows the oil price and as a consequence from this, LNG prices are also linked to the source of energy which it is primarily supposed to replace.

    Liquid natural gas (LNG) is an attractive transportation fuel because of its high heating value and energy density (i.e., Btu/lb. and Btu/gal.), clean burning characteristics, relatively low cost ($/Btu), and domestic availability. This research evaluated LNG vehicle and refueling system technology, economics, and safety. Prior and current LNG vehicle projects were studied to identify needed technology improvements. Life-cycle cost analyses considered various LNG vehicle and fuel supply options. Safety records, standards, and analysis methods were reviewed. The LNG market niche is centrally fueled heavy-duty fleet vehicles with high fuel consumption. For these applications, fuel cost savings can amortize equipment capital costs.

  15. Natural gas and CO2 price variation: impact on the relative cost-efficiency of LNG and pipelines.

    Ulvestad, Marte; Overland, Indra

    2012-06-01

    THIS ARTICLE DEVELOPS A FORMAL MODEL FOR COMPARING THE COST STRUCTURE OF THE TWO MAIN TRANSPORT OPTIONS FOR NATURAL GAS: liquefied natural gas (LNG) and pipelines. In particular, it evaluates how variations in the prices of natural gas and greenhouse gas emissions affect the relative cost-efficiency of these two options. Natural gas is often promoted as the most environmentally friendly of all fossil fuels, and LNG as a modern and efficient way of transporting it. Some research has been carried out into the local environmental impact of LNG facilities, but almost none into aspects related to climate change. This paper concludes that at current price levels for natural gas and CO2 emissions the distance from field to consumer and the volume of natural gas transported are the main determinants of transport costs. The pricing of natural gas and greenhouse emissions influence the relative cost-efficiency of LNG and pipeline transport, but only to a limited degree at current price levels. Because more energy is required for the LNG process (especially for fuelling the liquefaction process) than for pipelines at distances below 9100 km, LNG is more exposed to variability in the price of natural gas and greenhouse gas emissions up to this distance. If the prices of natural gas and/or greenhouse gas emission rise dramatically in the future, this will affect the choice between pipelines and LNG. Such a price increase will be favourable for pipelines relative to LNG.

    The World Wide Web consortium has developed an Extensible Markup Language (XML) to support the building of better information management infrastructures. The scientific computing community realizing the benefits of XML has designed markup languages for scientific data. In this paper, we propose a XML based scientific data management ,facility, XDMF. The project is motivated by the fact that even though a lot of scientific data is being generated, it is not being shared because of lack of standards and infrastructure support for discovering and transforming the data. The proposed data management facility can be used to discover the scientific data itself, the transformation functions, and also for applying the required transformations. We have built a prototype system of the proposed data management facility that can work on different platforms. We have implemented the system using Java, and Apache XSLT engine Xalan. To support remote data and transformation functions, we had to extend the XSLT specification and the Xalan package.

Novel clinical indications for the LNG-IUS, derived mainly from investigator-initiated studies, are emerging. These include heavy menstrual bleeding associated with uterine fibroids, endometriosis, adenomyosis, as well as endometrial hyperplasia. In both cohort and randomized studies, the LNG-IUS is effective in decreasing heavy menstrual bleeding, also in women diagnosed with uterine fibroids. In randomized studies the LNG-IUS has shown comparable clinical efficacy to GnRH analogues or progestins for the symptomatic treatment of endometriosis. Experience with LNG-IUS in adenomyosis is based on prospective cohort studies. Dysmenorrhea has been reported to decrease in all women, and uterine volume was seen to diminish in some of these studies. In the treatment of endometrial hyperplasias, including atypical hyperplasia, the LNG-IUS is equal or superior to treatment with systemic progestins. Further studies are needed to examine the full potential of the LNG-IUS in such common clinical situations.

    Theoretical and numerical analysis on the fluid flow and heat transfer inside a LNG evaporator is conducted in this work. Methane is used instead of LNG as the operating fluid. This is because; methane constitutes over 80% of natural gas. The analytical calculations are performed using simple mass and energy balance equations. The analytical calculations are made to assess the pressure and temperature variations in the steam tube. Multiphase numerical simulations are performed by solving the governing equations (basic flow equations of continuity, momentum and energy equations) in a portion of the evaporator domain consisting of a single steam pipe. The flow equations are solved along with equations of species transport. Multiphase modeling is incorporated using VOF method. Liquid methane is the primary phase. It vaporizes into the secondary phase gaseous methane. Steam is another secondary phase which flows through the heating coils. Turbulence is modeled by a two equation turbulence model. Both the theoretical and numerical predictions are seen to match well with each other. Further parametric studies are planned based on the current research.

    Sandia National Laboratories evaluated published safety assessment methods across a variety of industries including Liquefied Natural Gas (LNG), hydrogen, land and marine transportation, as well as the US Department of Defense (DOD). All the methods were evaluated for their potential applicability for use in the LNG railroad application. After reviewing the documents included in this report, as well as others not included because of repetition, the Department of Energy (DOE) Hydrogen Safety Plan Checklist is most suitable to be adapted to the LNG railroad application. This report was developed to survey industries related to rail transportation for methodologies and tools that can be used by the FRA to review and evaluate safety assessments submitted by the railroad industry as a part of their implementation plans for liquefied or compressed natural gas storage ( on-board or tender) and engine fueling delivery systems. The main sections of this report provide an overview of various methods found during this survey. In most cases, the reference document is quoted directly. The final section provides discussion and a recommendation for the most appropriate methodology that will allow efficient and consistent evaluations to be made. The DOE Hydrogen Safety Plan Checklist was then revised to adapt it as a methodology for the Federal Railroad Administration’s use in evaluating safety plans submitted by the railroad industry.

    The submerged combustion vaporizer (SCV) is indispensable general equipment for liquefied natural gas (LNG) receiving terminals. In this paper, numerical simulation was conducted to get insight into the flow and heat transfer characteristics of supercritical LNG on the tube-side of SCV. The SST model with enhanced wall treatment method was utilized to handle the coupled wall-to-LNG heat transfer. The thermal-physical properties of LNG under supercritical pressure were used for this study. After the validation of model and method, the effects of mass flux, outer wall temperature and inlet pressure on the heat transfer behaviors were discussed in detail. Then the non-uniformity heat transfer mechanism of supercritical LNG and effect of natural convection due to buoyancy change in the tube was discussed based on the numerical results. Moreover, different flow and heat transfer characteristics inside the bend tube sections were also analyzed. The obtained numerical results showed that the local surface heat transfer coefficient attained its peak value when the bulk LNG temperature approached the so-called pseudo-critical temperature. Higher mass flux could eliminate the heat transfer deteriorations due to the increase of turbulent diffusion. An increase of outer wall temperature had a significant influence on diminishing heat transfer ability of LNG. The maximum surface heat transfer coefficient strongly depended on inlet pressure. Bend tube sections could enhance the heat transfer due to secondary flow phenomenon. Furthermore, based on the current simulation results, a new dimensionless, semi-theoretical empirical correlation was developed for supercritical LNG convective heat transfer in a horizontal serpentine tube. The paper provided the mechanism of heat transfer for the design of high-efficiency SCV.

The paper is based on clinical reports of 21 cases of primary and secondary dysmenorrhea treated with the frameless LNG-IUS. Three typical examples of young women between 16 and 20 years of age, who presented with moderate-to-severe primary dysmenorrhea associated with heavy menstrual bleeding, are presented as examples. Following pelvic examination, including vaginal sonography, a frameless LNG-IUS, releasing 20 µg of LNG/day, was inserted. The three patients developed amenorrhea, or scanty menstrual bleeding, and absence of pain complaints within a few months. We conclude that continuous, intrauterine progestogen delivery could be a treatment of choice of this inconvenient condition. In addition, the good experiences with the frameless LNG-IUS in other studies suggests that the frameless design may be preferred over a framed LNG-IUS, as the absence of a frame, resulting in optimal tolerance, is particularly advantageous in these women.

    Although still far from being a commodity, LNG is undoubtedly emerging as an essential vector for world gas expansion. The flexibility it procures in terms of supply is of prime importance for future market equilibrium. Despite a number of uncertainties and constraints liable to thwart the realisation of the most optimistic growth prospects, the LNG trade remains wedded to rapid growth of about 7%/year by 2020, boosting its share of world gas trade to some 38% by that horizon.

    Full Text Available LNG tanks are complex in design and building process and high in costs, so LNG tank technology is one of the most advanced ones in the field of energy, which has been monopolized by foreign companies for a long time. In order to work out LNG tank technology domestically, China National Offshore Oil Corporation (CNOOC for short, the largest LNG importer in China, develops a LNG tank technology system “CGTank®” successfully in reference to the design and construction experience of domestic and foreign companies, after years of scientific research in tackling difficult problems. This system presents four traits as follows. First, a set of calculation software is developed independently by CNOOC, and the tanks in all operating conditions are calculated after 3D hologram and multi-point contact model of fluid-solid coupling effect is built up. Second, earthquake effect research and inner tank check research are improved innovatively by means of response spectrum analysis after European standards are introduced. Third, it is put forward for the first time that the stress strength discrimination standard is based on the principal stress which is obtained by means of the maximum shearing failure theory. And fourth, a large LNG full-capacity tank technology package with completely independent intellectual property right is established. The “CGTank®” system was first applied in the Tianjin LNG demonstration project, which has passed all indicator tests and is now in operation smoothly. The project is provided with the core tank design technology by CNOOC Gas and Power Group and with the EPC by CNOOC Engineering Co., Ltd. The independent LNG tank technology can be applied in a wide scope and it is favorable for impelling domestic production of LNG industry completely.

    Enterotoxigenic Escherichia coli (ETEC) is a major cause of morbidity in children under 5 years of age in low- and middle-income countries and a leading cause of traveler's diarrhea worldwide. The ability of ETEC to colonize the intestinal epithelium is mediated by fimbrial adhesins, such as CS21 (Longus). This adhesin is a type IVb pilus involved in adherence to intestinal cells in vitro and bacterial self-aggregation. Fourteen open reading frames have been proposed to be involved in CS21 assembly, hitherto only the lngA and lngB genes, coding for the major (LngA) and minor (LngB) structural subunit, have been characterized. In this study, we investigated the role of the LngA, LngB, LngC, LngD, LngH, and LngP proteins in the assembly of CS21 in ETEC strain E9034A. The deletion of the lngA, lngB, lngC, lngD, lngH, or lngP genes, abolished CS21 assembly in ETEC strain E9034A and the adherence to HT-29 cells was reduced 90%, compared to wild-type strain. Subcellular localization prediction of CS21 proteins was similar to other well-known type IV pili homologs. We showed that LngP is the prepilin peptidase of LngA, and that ETEC strain E9034A has another peptidase capable of processing LngA, although with less efficiency. Additionally, we present immuno-electron microscopy images to show that the LngB protein could be localized at the tip of CS21. In conclusion, our results demonstrate that the LngA, LngB, LngC, LngD, LngH, and LngP proteins are essential for CS21 assembly, as well as for bacterial aggregation and adherence to HT-29 cells.

    LNG custody transfer measurements at large terminals have been based on ship tank level gauging for more than 50 years. Flow meter application has mainly been limited to process control in spite of the promise of simplified operations, potentially smaller uncertainties and better control over the measurements for buyers. The reason for this has been the lack of LNG flow calibration standards as well as written standards. In the framework of the EMRP1 ‘Metrology for LNG’ project, Van Swinden Laboratory (VSL) has developed a primary LNG mass flow standard. This standard is so far the only one in the world except for a liquid nitrogen flow standard at the National Institute of Standards and Technology (NIST). The VSL standard is based on weighing and holds a Calibration and Measurement Capability (CMC) of 0.12% to 0.15%. This paper discusses the measurement principle, results of the uncertainty validation with LNG and the differences between water and LNG calibration results of four Coriolis mass flow meters. Most of the calibrated meters do not comply with their respective accuracy claims. Recommendations for further improvement of the measurement uncertainty will also be discussed.

    This article addressed the debate regarding the United States' proposal to construct liquefied natural gas (LNG) facilities on a pristine bay between New Brunswick and Maine. Two LNG projects are currently being promoted for Passamaquoddy Bay, and 2 more proposals are expected to be announced in the near future. However, the proponents have not yet submitted any formal applications to the Canadian government. A federal cabinet minister from New Brunswick has joined the growing opposition to the proposed project, claiming that the location on the Maine side of Passamaquoddy Bay, a large inlet off the Bay of Fundy, poses too many risks to the habitat of several endangered or at-risk species, including the North Atlantic Right Whale. The proposed sites in Maine are directly across a narrow bay where tourism and fishing are prime industries in New Brunswick. The cabinet minister claims that with over 2,000 miles of coastline on the eastern seaboard, another location can be found for the LNG facilities that would not present navigational difficulties. The Canadian federal government has the jurisdiction to stop the project by not allowing the supertankers to cross Canadian waters to enter the Bay. The waters are known for their treacherous navigation. The premier of New Brunswick has also stepped in to ensure that the governor of Maine is made aware of Canada's opposition to the project. Officials with Downeast LNG and Quoddy Bay LLC claim there would not be any safety or environmental risks associated with the LNG project.

    In order to reduce the atmospheric pollution generated by ships, the International Marine Organization has established Emission Controlled Areas. In these areas, nitrogen oxides, sulphur oxides and particulates emission is strongly controlled. From the beginning of 2015, the ECA covers waters 200 nautical miles from the coast of the US and Canada, the US Caribbean Sea area, the Baltic Sea, the North Sea and the English Channel. From the beginning of 2020, strong emission restrictions will also be in force outside the ECA. This requires newly constructed ships to be either equipped with exhaust gas cleaning devices or propelled with emission free fuels. In comparison to low sulphur Marine Diesel and Marine Gas Oil, LNG is a competitive fuel, both from a technical and economical point of view. LNG can be stored in vacuum insulated tanks fulfilling the difficult requirements of marine regulations. LNG must be vaporized and pressurized to the pressure which is compatible with the engine requirements (usually a few bar). The boil-off must be controlled to avoid the occasional gas release to the atmosphere. This paper presents an LNG system designed and commissioned for a Baltic Sea ferry. The specific technical features and exploitation parameters of the system will be presented. The impact of strict marine regulations on the system's thermo-mechanical construction and its performance will be discussed. The review of possible flow-schemes of LNG marine systems will be presented with respect to the system's cost, maintenance, and reliability.

    2010-08-15

    A new method for the analysis of LNG spills into trenches has been developed to quantify vapor dispersion hazard distances. The model uses three steps to capture the behavior of an LNG spill into a trench. The first is to analytically calculate the evolving LNG flow, the second to calculate the vaporization rate along the trench, and the third is to calculate the dispersion of the vapors using a CFD model that has been validated for this application in the presence of complex geometries. This paper presents case studies that show the effect of wind perpendicular and parallel to the large aspect ratio trenches on vapor dispersion. The case studies also demonstrate the effect of complex terrain and obstacles such as vapor fences on vapor dispersion. The simulations show that wind direction relative to the trench has a significant effect on cloud shape, height, and maximum downwind distance. The addition of vapor fences to mitigate vapor dispersion hazards from an LNG spill into the LNG containment trench is shown to be effective.

    With increasing consumption of natural gas, the safety of liquefied natural gas (LNG) utilization has become an issue that requires a comprehensive study on the risk of LNG spillage in facilities with mitigation measures. The immediate hazard associated with an LNG spill is the vapor hazard, i.e., a flammable vapor cloud at the ground level, due to rapid vaporization and dense gas behavior. It was believed that high expansion foam mitigated LNG vapor hazard through warming effect (raising vapor buoyancy), but the boil-off effect increased vaporization rate due to the heat from water drainage of foam. This work reveals the existence of blocking effect (blocking convection and radiation to the pool) to reduce vaporization rate. The blanketing effect on source term (vaporization rate) is a combination of boil-off and blocking effect, which was quantitatively studied through seven tests conducted in a wind tunnel with liquid nitrogen. Since the blocking effect reduces more heat to the pool than the boil-off effect adds, the blanketing effect contributes to the net reduction of heat convection and radiation to the pool by 70%. Water drainage rate of high expansion foam is essential to determine the effectiveness of blanketing effect, since water provides the boil-off effect.

    The helium bearing boil off gas (BOG) from liquid natural gas (LNG) storage tank in LNG plant, which has a helium concentration of about 1%, has attracted the attention in China as a new helium source. As the BOG is usually reused by re-condensing to recover methane, it is likely to cause continuous accumulation of nitrogen in the unit, thus a nitrogen removal process must be integrated. This paper describes a conceptional cryogenic separation system aiming at recovering methane, helium and nitrogen from BOG based on cryogenic distillation and condensation process.

    Full Text Available LNG (Liquified Narural Gas adalah gas alam yang telah diproses untuk menghilangkan ketidakmurnian dan hidrokarbon berat dan kemudian dikondensasi menjadi cairan pada tekan atmosfer dengan mendinginkannya sekitar -160° Celcius. LNG ditransportasi menggunakan kendaraan yang dirancang khusus dan ditaruh dalam tangki yang juga dirancang khusus. LNG memiliki isi sekitar 1/600 dari gas alam pada suhu dan tekanan standar, membuatnya lebih hemat untuk ditransportasi jarak jauh di mana jalur pipa tidak ada. Ketika memindahkan gas alam dengan jalur pipa tidak memungkinkan atau tidak ekonomis, dia dapat ditransportasi oleh suatu kapal pengangkut untuk LNG. Gas alam dapat digunakan sebagai bahan bakar untuk pembangkit listrik PLTG dan PLTU. Dari data ESDM cadangan gas alam tersebut dapat dikatakan bahwa potensi gas alam Indonesia sangatlah besar, karena pada data tahun 2012 ditjen migas tersebut, cadangan gas alam yang masih tersimpan dan tersebar di Indonesia masih sangat besar, dengan potensial sebesar 47.35 TSCF (Trillion Square Cubic Feet. Potensi tersebut adalah total dari seluruh potensi yang tersebar di Indonesia sebesar 150.70 TSCF. Pabrik Terminal Regasifikasi LNG direncanakan dibangun pada tahun 2014 dengan target siap beroperasi pada tahun 2016. Pabrik ini berlokasi di Celukan Bawang Bali dengan terdapat 3 PLTG yang membutuhkan distribusi LNG yaitu PLTG Gilimanuk, Pemaron, dan Pesanggaran. Kapasitas pabrik ini adalah 100 MMSCFD. Pabrik ini akan memenuhi kebutuhan pembangkit listrik untuk daerah Bali. Rangkaian proses pabrik ini adalah unit Regasification. Analisa ekonomi dari pabrik ini adalah investasi sebesar 371,66 MUSD, IRR sebesar 38,6%, POT selama 2,71 tahun, BEP sebesar 49,6% dan NPV 10 tahun sebesar 1011,82 MUSD.

  18. A structural and stochastic optimal model for projections of LNG imports and exports in Asia-Pacific.

    Science.gov (United States)

    Kompas, Tom; Che, Tuong Nhu

    2016-06-01

    The Asia-Pacific region, the largest and fastest growing liquefied natural gas (LNG) market in the world, has been undergoing radical changes over the past few years. These changes include considerable additional supplies from North America and Australia, and a recent LNG price slump resulting from an oil-linked pricing mechanism and demand uncertainties. This paper develops an Asia-Pacific Gas Model (APGM), based on a structural, stochastic and optimising framework, providing a valuable tool for the projection of LNG trade in the Asia-Pacific region. With existing social-economic conditions, the model projects that Asia-Pacific LNG imports are expected to increase by 49.1 percent in 2020 and 95.7 percent in 2030, compared to 2013. Total LNG trade value is estimated to increase to US$127.2 billion in 2020 and US$199.0 billion in 2030. Future LNG trade expansion is mainly driven by emerging and large importers (i.e., China and India), and serviced, most importantly, by new supplies from Australia and the USA. The model's projected results are sensitive to changes in expected oil prices, pricing mechanisms, economic growth and energy policies, as well as unexpected geopolitical-economic events.

  2. Process simulation for a new conceptual design of LNG terminal coupling NGL recovery and LNG re-gasification for maximum energy savings

    Science.gov (United States)

    Muqeet, Mohammed A.

    With the high demands of shale gas and promising development of LNG terminals, a lot of research has focused towards the process development for effective recovery of C2+ hydrocarbons (NGL). Shale gas requires a large amount of cold energy to cool down and recover the NGL; and the LNG re-gasification process requires a lot of heat energy to evaporate for NGL recovery. Thus, coupling the shale gas NGL recovery process and LNG re-gasification process, for utilizing the cold energy from LNG re-gasification process to assist NGL recovery from shale gas has significant economic benefits on both energy saving and high value product recovery. Wang et al. developed new conceptual design of such coupled process in 2013 and later Wang and Xu developed an optimal design considering uncertainties in 2014. This work deals with process simulation of both these designs and the feasibility of the process is verified. A steady state model is developed based on the plant design proposed by Wang et al. using Aspen plusRTM and then a dynamic model of the process is developed using Aspen dynamicsRTM. An effective control strategy is developed and the flexibility of the dynamic model is examined by giving disturbances in the shale gas feed. A comparison is made between the two proposed design and the prospects of the design for real plant scenario is discussed.

    The study aims at clarifying the framework for possible LNG exports from Northern Russia and focuses on the European natural gas markets. The first stage provides general background information on the market structure and related topics. In the second stage this information is used to develop a formal market model and subject it to simulations with various assumptions of the future gas supply. The model is described and results from simulations are given. In the first stage facts from the history of the European natural gas market are outlined. Underlying conditions for the development of natural gas markets in Europe are addressed. The EU has been promoting trade liberalisation in the energy sector but most counties resist freer gas trade across the boarders. New infrastructure development for natural gas are either underway or planned. Some important projects are mentioned. Gas in a global perspective is discussed. The cost structure of the LNG chain is mentioned and an overview of existing LNG export capacities world-wide and major reception terminals in Europe and the USA is given. The second stage employs a scenario analysis to evaluate the economic effects of hypothetical LNG deliveries from Northern Russia. The model is developed for the analysis of West European natural gas markets and designed to allow users to create a structural system of interconnected producers and market regions. Basic assumptions for the evolution of natural gas markets till 2005 is developed and base case scenarios calculated for the years 2000 and 2005 and used as a point of reference for the alternative scenarios considered. According to the analysis the introduction of a new LNG supplier in the European gas market will inflict a substantial loss upon all the existing producers. The primary keys to this result are the assumptions made for gas demand and supply capacity. The LNG alternative will hardly be approved for purely economic reasons as long as the Russians maintain

    unless a significant station capital subsidy, upwards of 50 percent and even then it might not be enough. However, a doubling of LNG truck demand will initialize network commercialization in the modeling base year, 2012 (the same year Clean Energy Corp. launched their national LNG network) in California and then gradually establish in other hotspot regions in Mid-West and Mid-Atlantic throughout the time horizon. The model shows that trucking routes in California are highly commercial due to high traffic volume and regional advantages. The model can be used by industry to inform necessary policies and to plan future infrastructure deployment along trucking routes that are likely to provide the highest returns.

    Post-consumer PET bottle recycling is attracting increasing attention due to its value as an energy conservation and environmental protection measure. Sorting by color is a common method in bottle recycling; however, manual operations are unstable and time consuming. In this paper, we design a vision-based facility to perform high-speed bottle sorting. The proposed facility consists mainly of electric and mechanical hardware and image processing software. To solve the recognition problem of isolated and overlapped bottles, we propose a new shape descriptor and utilize the support vector data description classifier. We use color names to represent the colors in the real world in order to avoid problems introduced by colors that are similar. The facility is evaluated by the target error, outlier error and total error. The experimental results demonstrate that the facility we developed is capable of recycling various PET bottles.

    Last year, 51 LNG carriers were delivered in the world. From January to February this year, more than 10 LNG carriers have been deliveredglobally. Some shipowners are planning to expand LNG carrier fleet, which is a stark contrast to the look of the three main ship types which is embarrassing. As the recognized clean fuel, natural gas plays an important role in carbon politics and low carbon economy. At present, LNG powered vessel is growing vigorously. LNG fueled vessels have also emerged in Europe. Now, discussion about natural gas application on inland water transport is gradually warming up. Although there are still many technical problems to be solved about LNG powered vessel, the trend is irreversible.

    Full Text Available Production of unconventional gas plays a double role in the case of liquefied natural gas (LNG industry. Technological development of gas production from unconventional resources could result in significant decrease of LNG import demand but at the same time unconventional resources also represent a potential for new sources of LNG supply. In past few years unconventional gas production in North America has increased constantly what has contributed to natural gas prices decrease and LNG imports reduction. The rise of unconventional gas production along with global recession significantly influenced LNG demand decrease in the USA. Concerning unconventional gas production rapid development, potential decrease of LNG demand in rest of the world is expected (the paper is published in Croatian.

  11. Development of mass production type rigid polyurethane foam for LNG carrier using ozone depletion free blowing agent

    Lee, Yeongbeom; Baek, Kye Hyun; Choe, Kunhyung; Han, Chonghun

    2016-12-01

    Nowadays the price of natural gas has become higher and the efficiency of propulsion system of liquefied natural gas (LNG) carriers has improved. Due to these trends, required boil-off rate (BOR) for LNG carrier has been lowered from 0.15%/day to 0.12%/day for conventional LNG carriers with sizes between 125,000 m3 and 170,000 m3. This requirement of BOR can be satisfied by using a rigid polyurethane foam (PUF) blown by 1,1-dichloro-1-fluoroethane (HCFC-141b) as an insulator. However, ozone depletion potential (ODP) of HCFC-141b requires alternative blowing agents with zero ODP such as hydroflurocarbons (HFCs) because of tougher environmental regulations. This paper introduces use of HFCs and additives to enhance properties of rigid PUFs under a mass production environment. Among the additives, perfluoroalkane (PFA) reduces thermal conductivity down to 12% and increases compressive strength up to 15% of a rigid PUF prepared in a laboratory scale. Based on this result, a mass production type rigid PUF is manufactured and is evaluated for BOR, mechanical strengths over operation temperature range, and thermal shock stability for LNG carriers. The BOR of the manufactured rigid PUF is below 0.12%/day, which satisfies the recent BOR specification for LNG carriers. The other required properties are also met the specifications for a conventional LNG carrier. Consequently, it is expected that the results in this paper will bring low BOR (LNG carries with rigid PUFs using ODP free blowing agents and contribute environmental protection through saving energy and preserving the ozone layer in the stratosphere.

    Automated User's Training Operations Facility Utilization Request (AutoFUR) is prototype software that administers a Web-based system for requesting and allocating facilities and equipment for astronaut-training classes in conjunction with scheduling the classes. AutoFUR also has potential for similar use in such applications as scheduling flight-simulation equipment and instructors in commercial airplane-pilot training, managing preventive- maintenance facilities, and scheduling operating rooms, doctors, nurses, and medical equipment for surgery. Whereas requesting and allocation of facilities was previously a manual process that entailed examination of documents (including paper drawings) from different sources, AutoFUR partly automates the process and makes all of the relevant information available via the requester s computer. By use of AutoFUR, an instructor can fill out a facility-utilization request (FUR) form on line, consult the applicable flight manifest(s) to determine what equipment is needed and where it should be placed in the training facility, reserve the corresponding hardware listed in a training-hardware inventory database, search for alternative hardware if necessary, submit the FUR for processing, and cause paper forms to be printed. Auto-FUR also maintains a searchable archive of prior FURs.

    At the request of GDF Suez, a Rough Order of Magnitude (ROM) cost estimate was prepared for the design, construction, testing, and data analysis for an experimental series of large-scale (Liquefied Natural Gas) LNG spills on land and water that would result in the largest pool fires and vapor dispersion events ever conducted. Due to the expected cost of this large, multi-year program, the authors utilized Sandia's structured cost estimating methodology. This methodology insures that the efforts identified can be performed for the cost proposed at a plus or minus 30 percent confidence. The scale of the LNG spill, fire, and vapor dispersion tests proposed by GDF could produce hazard distances and testing safety issues that need to be fully explored. Based on our evaluations, Sandia can utilize much of our existing fire testing infrastructure for the large fire tests and some small dispersion tests (with some modifications) in Albuquerque, but we propose to develop a new dispersion testing site at our remote test area in Nevada because of the large hazard distances. While this might impact some testing logistics, the safety aspects warrant this approach. In addition, we have included a proposal to study cryogenic liquid spills on water and subsequent vaporization in the presence of waves. Sandia is working with DOE on applications that provide infrastructure pertinent to wave production. We present an approach to conduct repeatable wave/spill interaction testing that could utilize such infrastructure.

    A group of European gas transportation companies within the European Gas Research Group launched in 2007 the 'MOLAS' Project to provide a software program for the analysis of the Liquefied Natural Gas (LNG) ageing process during ship transportation. This program contains two different modeling approaches: a physical algorithm and an 'intelligent' model. Both models are fed with the same input data, which is composed of the ship characteristics (BOR and capacity), voyage duration, LNG composition, temperature, pressure, and volume occupied by liquid phase at the port of origin, together with pressure at the port of destination. The results obtained are the LNG composition, temperature and liquid volume at the port of destination. Furthermore, the physical model obtains the evolution over time of such variables en route as it is based on unsteady mass balances over the system, while the i-model applies neural networks to obtain regression coefficients from historical data composed only of origin and destination measurements. This paper describes both models and validates them from previous published models and experimental data measured in ENAGAS LNG regasification plants. (author)

    Full Text Available Enterotoxigenic Escherichia coli (ETEC is a major cause of morbidity in children under 5 years of age in low- and middle-income countries and a leading cause of traveler's diarrhea worldwide. The ability of ETEC to colonize the intestinal epithelium is mediated by fimbrial adhesins, such as CS21 (Longus. This adhesin is a type IVb pilus involved in adherence to intestinal cells in vitro and bacterial self-aggregation. Fourteen open reading frames have been proposed to be involved in CS21 assembly, hitherto only the lngA and lngB genes, coding for the major (LngA and minor (LngB structural subunit, have been characterized. In this study, we investigated the role of the LngA, LngB, LngC, LngD, LngH, and LngP proteins in the assembly of CS21 in ETEC strain E9034A. The deletion of the lngA, lngB, lngC, lngD, lngH, or lngP genes, abolished CS21 assembly in ETEC strain E9034A and adherence to HT-29 cells was reduced 90%, compared to wild-type strain. Subcellular localization prediction of CS21 proteins was similar to other well-known type IV pili homologues. We showed that LngP is the prepilin peptidase of LngA, and that ETEC strain E9034A has another peptidase capable of processing LngA, although with less efficiency. Additionally, we present immuno-electron microscopy imagens to show that the LngB protein could be localized at the tip of CS21, and probably helps to control CS21 length. In conclusion, our results demonstrate that the LngA, LngB, LngC, LngD, LngH, and LngP proteins are essential for CS21 assembly, as well as for bacterial aggregation and adherence to HT-29 cells.

    2007-02-20

    During the period from 1977 to 1989, the Lawrence Livermore National Laboratory (LLNL) conducted a liquefied gaseous fuels spill effects program under the sponsorship of the US Department of Energy, Department of Transportation, Gas Research Institute and others. The goal of this program was to develop and validate tools that could be used to predict the effects of a large liquefied gas spill through the execution of large scale field experiments and the development of computer models to make predictions for conditions under which tests could not be performed. Over the course of the program, three series of LNG spill experiments were performed to study cloud formation, dispersion, combustion and rapid phase transition (RPT) explosions. The purpose of this paper is to provide an overview of this program, the lessons learned from 12 years of research as well as some recommendations for the future. The general conclusion from this program is that cold, dense gas related phenomena can dominate the dispersion of a large volume, high release rate spill of LNG especially under low ambient wind speed and stable atmospheric conditions, and therefore, it is necessary to include a detailed and validated description of these phenomena in computer models to adequately predict the consequences of a release. Specific conclusions include: * LNG vapor clouds are lower and wider than trace gas clouds and tend to follow the downhill slope of terrain due to dampened vertical turbulence and gravity flow within the cloud. Under low wind speed, stable atmospheric conditions, a bifurcated, two lobed structure develops. * Navier-Stokes models provide the most complete description of LNG dispersion, while more highly parameterized Lagrangian models were found to be well suited to emergency response applications. * The measured heat flux from LNG vapor cloud burns exceeded levels necessary for third degree burns and were large enough to ignite most flammable materials. * RPTs are of two

    2015-01-01

    A plant operator training simulator is developed for training the plant operators as well as for design verification of plant control system (PCS) and plant protection system (PPS) for the Kharkov Institute of Physics and Technology Neutron Source Facility. The simulator provides the operator interface for the whole plant including the sub-critical assembly coolant loop, target coolant loop, secondary coolant loop, and other facility systems. The operator interface is implemented based on Experimental Physics and Industrial Control System (EPICS), which is a comprehensive software development platform for distributed control systems. Since its development at Argonne National Laboratory, it has been widely adopted in the experimental physics community, e.g. for control of accelerator facilities. This work is the first implementation for a nuclear facility. The main parts of the operator interface are the plant control panel and plant protection panel. The development involved implementation of process variable database, sequence logic, and graphical user interface (GUI) for the PCS and PPS utilizing EPICS and related software tools, e.g. sequencer for sequence logic, and control system studio (CSS-BOY) for graphical use interface. For functional verification of the PCS and PPS, a plant model is interfaced, which is a physics-based model of the facility coolant loops implemented as a numerical computer code. The training simulator is tested and demonstrated its effectiveness in various plant operation sequences, e.g. start-up, shut-down, maintenance, and refueling. It was also tested for verification of the plant protection system under various trip conditions.

    2015-06-01

    Full Text Available A thermal Neutron Radiography (NR facility based on the use of thermal neutron flux, generated by the PULSTAR experimental reactor, has been designed and simulated using the MCNPX code. The key objective of the proposed facility is to deliver thermal neutron flux in this range for variable values of L/D ratio, instantaneously with acceptable values for all NR parameters. Thus, with suitable aperture and collimators designs, optimization for the parameters for thermal NR was achieved, for a wide range of the collimator ratio. The short time requirements for obtaining the radiography images justify the use of the proposed system for ‘real time radiography’. The system was designed under the limitation that the total Dose Equivalent Rate does not exceed at the external shield surface the limit recommended by ICRP-26.

    2013-02-15

    The growing importance of liquefied natural gas (LNG) to global energy demand has increased interest in the possible hazards associated with its storage and transportation. Concerning the event of an LNG spill, a study was performed on the relationship between the distance at which the lower flammability limit (LFL) concentration occurs and that corresponding to the visible contour of LNG vapor clouds. A parameter called the dispersion safety factor (DSF) has been defined as the ratio between these two lengths, and two expressions are proposed to estimate it. During an emergency, the DSF can be a helpful parameter to indicate the danger of cloud ignition and flash fire.

    2014-06-01

    SSPA experiences a growing interest in twin skeg ships as one attractive green ship solution. The twin skeg concept is well proven with obvious advantages for the design of ships with full hull forms, restricted draft or highly loaded propellers. SSPA has conducted extensive hull optimizations studies of LNG ships of different size based on an extensive hull data base with over 7,000 models tested, including over 400 twin skeg hull forms. Main hull dimensions and different hull concepts such as twin skeg and single screw were of main interest in the studies. In the present paper, one twin skeg and one single screw 170 K LNG ship were designed for optimally selected main dimension parameters. The twin skeg hull was further optimized and evaluated using SHIPFLOW FRIENDSHIP design package by performing parameter variation in order to modify the shape and positions of the skegs. The finally optimized models were then built and tested in order to confirm the lower power demand of twin skeg designed compaed with the signle screw design. This paper is a full description of one of the design developments of a LNG twin skeg hull, from early dimensional parameter study, through design optimization phase towards the confirmation by model tests.

  5. A Tether-Based Variable-Gravity Research Facility Concept

    Science.gov (United States)

    Sorensen, Kirk

    2006-01-01

    The recent announcement of a return to the Moon and a mission to Mars has made the question of human response to lower levels of gravity more important. Recent advances in tether technology spurred by NASA s research in MXER tethers has led to a re-examination of the concept of a variable-gravity research facility (xGRF) for human research in low Earth orbit. Breakthroughs in simplified inertial tracking have made it possible to consider eliminating the despun section of previous designs. This, in turn, improves the prospect of a facility based entirely around a tether, with the human module on one end and a countermass on the other. With such a configuration, propellantless spinup and spindown is also possible based on the conservation of angular momentum from a gravity-gradient configuration to a spinning configuration. This not only saves large amounts of propellant but vastly simplifies crew and consumable resupply operations, since these can now be done in a microgravity configuration. The importance of the science to be obtained and the performance improvements in this new design argue strongly for further investigation.

    Xu, Wendong; Duan, Jiao; Mao, Wenjun

    2014-02-01

    In order to resolve the problems of the current air separation process such as the complex process, cumbersome operation and high operating costs, a novel air separation process cooled by LNG cold energy is proposed in this paper, which is based on high-efficiency heat exchanger network and chemical packing separation technology. The operating temperature range of LNG cold energy is widened from 133K-203K to 113K-283K by high-efficiency heat exchanger network and air separation pressure is declined from 0.5MPa to about 0.35MPa due to packing separation technology, thereby greatly improve the energy efficiency. Both the traditional and novel air separation processes are simulated with air handling capacity of 20t·h-1. Comparing with the traditional process, the LNG consumption is reduced by 44.2%, power consumption decrease is 211.5 kWh per hour, which means the annual benefit will be up to 1.218 million CNY. And the exergy efficiency is also improved by 42.5%.

  10. LNG : its potential impact on North American markets

    Energy Technology Data Exchange (ETDEWEB)

    Schlesinger, B. [Benjamin Schlesinger and Associates Inc., Bethesda, MD (United States)

    2003-07-01

    Liquefied natural gas (LNG) is expected to play a greater role in North American gas supplies and markets due to the decrease in conventional natural gas production in North America accompanied by an increase in demand for energy. It is expected that the overall share of the LNG gas market will rise from about 1.4 per cent in 2002 to more than 5 per cent by 2020, and potentially up to 15 per cent by that year. The construction of at least 15 new LNG receiving terminals has been proposed for location in the U.S., Canada, and Mexico. In addition, El Paso has proposed a novel offshore LNG receiving concept involving offshore gas pipelines and on-board-ship regasification. As trading of LNG increases in the Atlantic, markets in eastern United States and Canada will benefit from improved gas supplies, but pricing patterns are expected to change. Basis differentials along the Atlantic coastline will probably diminish, potentially reducing the value of Sable Island gas and the pipeline system that runs north to south along the eastern coast of North America. It was noted that Middle Eastern suppliers of LNG will play an important potential role in North American markets. 19 figs.

    Science.gov (United States)

    Trimble, Virginia; Zaich, Paul; Bosler, Tammy

    2006-04-01

    In 2001, 18 journals published about 1270 astronomical papers that reported and/or analyzed data gathered by space-based observatories and missions. These papers were cited 24,460 times in papers published in 2002-2004, an average of 19.26 citations per paper or 6.42 citations per paper per year (sometimes called impact or impact factor). About 60 satellites, rockets, balloons, and planetary missions were represented, including six ground-based Cerenkov detectors for ultra-high energy gamma rays, because we didn't know where else to put them. Of these facilities, 21 provided the data for at least five papers, when credit was divided equally among all contributing facilities. We analyze here distributions of papers, citations, and impact factors among the facilities and among subject areas and compare the results with studies of optical and radio telescopes (Trimble et al. and Trimble & Zaich). Some similarities include the rarity of completely uncited papers (only 41 of 1274, or 3.2%) and the concentrations of the most highly cited papers toward popular topics, high-profile journals, and the most successful telescopes of the year. Some important differences arise because many space-based observatories have lifetimes shorter than the typical time required to think of an interesting astronomical observation, propose for it, get the data, write the paper and publish it (including the fight with the referee), and have citations accumulate. The result is superstar status in citation numbers for XMM-Newton (whose first-light package appeared in 2001) and in paper numbers for Chandra (launched 5 months earlier), while aging satellites (RXTE, BeppoSAX, ASCA) and the archival-only ROSAT, ISO, IRAS, etc., were still important contributors, but with fewer papers and less highly cited papers. The impact factor of 6.42 for the totality of these gamma-ray, X-ray, ultraviolet, space infrared and optical, and planetary mission papers (6.42) was larger than the corresponding radio

    2014-12-01

    Full Text Available Ever growing energy industry requires larger quantities of LNG to be transported by bigger ships between terminals. Every day, new kind of large vessels created by new technologies, and these are used to trade around the globe. This is the dynamic change in shipping industry. But on the other hand these new vessels need to safely berth to existing terminals which we may accept as more static part of the trade. Thus this study born by the request of Ege Gaz Aliaga LNG Terminal management to determine if it is safe to berth to the terminal by a new breed of large LNG carrier type named as Q-Flex and Q-Max. Transas Bridge Simulator NTPRO 5000 series was used in this study for extensive experiments which had been simulated by the use of hook function. During the study, every force applied to mooring hooks and dolphins by the ship lines were divided into 3 dimensions and then measured by simulation experiments. With analysis of the data, required hook and dolphins strengths were determined for the safe mooring arrangements. Upon the completion of the study Ege Gaz Aliaga LNG Terminal became the first safe berth for Q-Flex type vessels in the Mediterranean and the Black Sea. And finally all experiments were confirmed with real life experience when the first Q-Flex type LNG carrier berthed to the Ege Gaz Aliaga LNG Terminal.

  15. LNG pool fire spectral data and calculation of emissive power.

    Science.gov (United States)

    Raj, Phani K

    2007-04-11

    Spectral description of thermal emission from fires provides a fundamental basis on which the fire thermal radiation hazard assessment models can be developed. Several field experiments were conducted during the 1970s and 1980s to measure the thermal radiation field surrounding LNG fires. Most of these tests involved the measurement of fire thermal radiation to objects outside the fire envelope using either narrow-angle or wide-angle radiometers. Extrapolating the wide-angle radiometer data without understanding the nature of fire emission is prone to errors. Spectral emissions from LNG fires have been recorded in four test series conducted with LNG fires on different substrates and of different diameters. These include the AGA test series of LNG fires on land of diameters 1.8 and 6m, 35 m diameter fire on an insulated concrete dike in the Montoir tests conducted by Gaz de France, a 1976 test with 13 m diameter and the 1980 tests with 10 m diameter LNG fire on water carried out at China Lake, CA. The spectral data from the Montoir test series have not been published in technical journals; only recently has some data from this series have become available. This paper presents the details of the LNG fire spectral data from, primarily, the China Lake test series, their analysis and results. Available data from other test series are also discussed. China Lake data indicate that the thermal radiation emission from 13 m diameter LNG fire is made up of band emissions of about 50% of energy by water vapor (band emission), about 25% by carbon dioxide and the remainder constituting the continuum emission by luminous soot. The emissions from the H2O and CO2 bands are completely absorbed by the intervening atmosphere in less than about 200 m from the fire, even in the relatively dry desert air. The effective soot radiation constitutes only about 23% during the burning period of methane and increases slightly when other higher hydrocarbon species (ethane, propane, etc.) are

  14. LNG cascading damage study. Volume I, fracture testing report.

    Energy Technology Data Exchange (ETDEWEB)

    Petti, Jason P.; Kalan, Robert J.

    2011-12-01

    As part of the liquefied natural gas (LNG) Cascading Damage Study, a series of structural tests were conducted to investigate the thermal induced fracture of steel plate structures. The thermal stresses were achieved by applying liquid nitrogen (LN{sub 2}) onto sections of each steel plate. In addition to inducing large thermal stresses, the lowering of the steel temperature simultaneously reduced the fracture toughness. Liquid nitrogen was used as a surrogate for LNG due to safety concerns and since the temperature of LN{sub 2} is similar (-190 C) to LNG (-161 C). The use of LN{sub 2} ensured that the tests could achieve cryogenic temperatures in the range an actual vessel would encounter during a LNG spill. There were four phases to this test series. Phase I was the initial exploratory stage, which was used to develop the testing process. In the Phase II series of tests, larger plates were used and tested until fracture. The plate sizes ranged from 4 ft square pieces to 6 ft square sections with thicknesses from 1/4 inches to 3/4 inches. This phase investigated the cooling rates on larger plates and the effect of different notch geometries (stress concentrations used to initiate brittle fracture). Phase II was divided into two sections, Phase II-A and Phase II-B. Phase II-A used standard A36 steel, while Phase II-B used marine grade steels. In Phase III, the test structures were significantly larger, in the range of 12 ft by 12 ft by 3 ft high. These structures were designed with more complex geometries to include features similar to those on LNG vessels. The final test phase, Phase IV, investigated differences in the heat transfer (cooling rates) between LNG and LN{sub 2}. All of the tests conducted in this study are used in subsequent parts of the LNG Cascading Damage Study, specifically the computational analyses.

    RWE operates a LNG plant for peak shaving at Dormagen-Nievenheim as part of the RWE high-pressure gas supply grid. The natural gas is liquefied on site. This requires a complex liquefaction plant whose key elements are a tank, a heat exchanger, and the compressor. The plant was constructed and commissioned in 1975. After a longish standstill period, it was modernized recently, and several minor defects were repaired. The repair process is described in this contribution. It comprised damage detection and repair and was a time-consuming process. On the other hand, it illustrates that piston compressors function very reliably if regular servicing is ensured. (orig.)

  19. Concept for an advanced exotic beam facility based on ATLAS

    Rehm, K.E.; Ahmad, I.; Back, B.B. [and others

    1995-08-01

    The acceleration of beams of unstable nuclei has opened up new research frontiers. Experiments at existing accelerators, and particularly at the first generation of radioactive ion beam facilities, have demonstrated convincingly that unique information becomes accessible. Critical cross sections for astrophysical processes that were impossible to obtain previously, qualitatively new and unexpected nuclear structure effects in nuclei far from stability, completely new approaches to studies of nuclear decays, reactions and structure, all have triggered much excitement for this new dimension in nuclear research. To explore this new dimension, an extension of present technical capabilities and facilities is needed. This need and its scientific basis were discussed in various workshops and symposia and in the Isospin Laboratory (ISL) White Paper. A report by the European community was published recently on prospects of radioactive beam facilities in Europe, and some next-generation projects for such facilities are starting in both Europe and Japan.

  20. Hawaii energy strategy project 2: Fossil energy review. Task 3 -- Greenfield options: Prospects for LNG use

    Energy Technology Data Exchange (ETDEWEB)

    Breazeale, K. [ed.; Fesharaki, F.; Fridley, D.; Pezeshki, S.; Wu, K.

    1993-12-01

    This paper begins with an overview of the Asia-Pacific LNG market, its major players, and the likely availability of LNG supplies in the region. The discussion then examines the possibilities for the economic supply of LNG to Hawaii, the potential Hawaiian market, and the viability of an LNG project on Oahu. This survey is far from a complete technical assessment or an actual engineering/feasibility study. The economics alone cannot justify LNG`s introduction. The debate may continue as to whether fuel diversification and environmental reasons can outweigh the higher costs. Several points are made. LNG is not a spot commodity. Switching to LNG in Hawaii would require a massive, long-term commitment and substantial investments. LNG supplies are growing very tight in the Asia-Pacific region. Some of the environmental benefits of LNG are not entirely relevant in Hawaii because Hawaii`s air quality is generally excellent. Any air quality benefits may be more than counterbalanced by the environmental hazards connected with large-scale coastal zone construction, and by the safety hazards of LNG carriers, pipelines, etc. Lastly, LNG is not suitable for all energy uses, and is likely to be entirely unsuitable for neighbor island energy needs.

    Gemini's Base Facilities Operations (BFO) Project provided the capabilities to perform routine nighttime operations without anyone on the summit. The expected benefits were to achieve money savings and to become an enabler of the future development of remote operations. The project was executed using a tailored version of Prince2 project management methodology. It was schedule driven and managing it demanded flexibility and creativity to produce what was needed, taking into consideration all the constraints present at the time: Time available to implement BFO at Gemini North (GN), two years. The project had to be done in a matrix resources environment. There were only three resources assigned exclusively to BFO. The implementation of new capabilities had to be done without disrupting operations. And we needed to succeed, introducing the new operational model that implied Telescope and instrumentation Operators (Science Operations Specialists - SOS) relying on technology to assess summit conditions. To meet schedule we created a large number of concurrent smaller projects called Work Packages (WP). To be reassured that we would successfully implement BFO, we initially spent a good portion of time and effort, collecting and learning about user's needs. This was done through close interaction with SOSs, Observers, Engineers and Technicians. Once we had a clear understanding of the requirements, we took the approach of implementing the "bare minimum" necessary technology that would meet them and that would be maintainable in the long term. Another key element was the introduction of the "gradual descent" concept. In this, we increasingly provided tools to the SOSs and Observers to prevent them from going outside the control room during nighttime operations, giving them the opportunity of familiarizing themselves with the new tools over a time span of several months. Also, by using these tools at an early stage, Engineers and Technicians had more time for debugging

  3. Rapid response calculation of LNG cargo containment system under sloshing load using wavelet transformation

    Science.gov (United States)

    Kim, Yooil

    2013-06-01

    Reliable strength assessment of the Liquefied Natural Gas (LNG) cargo containment system under the sloshing impact load is very difficult task due to the complexity of the physics involved in, both in terms of the hydrodynamics and structural mechanics. Out of all those complexities, the proper selection of the design sloshing load which is applied to the structural model of the LNG cargo containment system, is one of the most challenging one due to its inherent randomness as well as the statistical analysis which is tightly linked to the design sloshing load selection. In this study, the response based strength assessment procedure of LNG cargo containment system has been developed and proposed as an alternative design methodology. Sloshing pressure time history, measured from the model test, is decomposed into wavelet basis function targeting the minimization of the number of the basis function together with the maximization of the numerical efficiency. Then the response of the structure is obtained using the finite element method under each wavelet basis function of different scale. Finally, the response of the structure under entire sloshing impact time history is rapidly calculated by synthesizing the structural response under wavelet basis function. Through this analysis, more realistic response of the system under sloshing impact pressure can be obtained without missing the details of pressure time history such as rising pattern, oscillation due to air entrapment and decay pattern and so on. The strength assessment of the cargo containment system is then performed based on the statistical analysis of the stress peaks selected out of the obtained stress time history.

  4. Egypt emerges : with help from some Canadian companies, Alexandria is striving to grab a spot on the global LNG stage

    Energy Technology Data Exchange (ETDEWEB)

    Lorenz, A.

    2006-12-15

    Two new liquefied natural gas (LNG) plants recently built in Egypt are a testimony to the country's renewed natural gas industry. This article presented details of Canadian companies who are now operating in Egypt as a result of the Egyptian government's decision to include gas as a commodity from which foreign companies could earn a profit in the late 1980s. Apache negotiated a lease on a 2.2 million acre block southwest of Giza called the Qarun Block along with a partner called Phoenix Resources Companies Inc. in 1992, and has since made significant gas discoveries. In March 2006, the company posted record gross oil and gas production of 119,500 barrels per day and 501 million cubic feet per day. Egypt currently produces 3.5 billion cubic feet of natural gas per day. Approximately half is consumed locally and the balance is liquefied for export to Europe and Asian markets. The 2 LNG plants in Egypt currently process 700 million cubic feet and 1 billion cubic feet per day respectively. Egypt's Nile Delta is emerging as a world-class hydrocarbon basin, where companies such as BP have been exploring and producing since 1992. BP is confident that Egypt's potential reserves exceed 100 trillion cubic feet and that its aggressive exploration strategy is expected to form the foundation of a significant LNG business. Calgary-based company Centurion has established a presence in Egypt and has formed a partnership with Royal Dutch/Shell Group. The company has granted Shell 2 concessions in exchange for the construction of a gas train worth $1.5 billion capable of handling 500 million cubic feet per day of gas. It was concluded that while current global prices for natural gas are still too low to make it economical to ship Egyptian LNG to North America, higher prices may mean that LNG currently being transported to Europe may eventually end up in North American LNG terminals. 9 figs.

    1998-01-08

    The existing superconducting linac ATLAS is in many respects an ideal secondary beam accelerator for an ISOL (Isotope separator on-line) type radioactive beam facility. Such a facility would require the addition of two major accelerator elements: a low charge state injector for the existing heavy ion linac, and a primary beam accelerator providing 220 MV of acceleration for protons and light ions. Development work for both of these elements, including the option of superconducting cavities for the primary beam accelerator is discussed.

    Highlights: ► We proposed a new parameter: the dispersion safety factor (DSF). ► DSF is the ratio between the distance reached by the LFL and that reached by the visible cloud. ► The results for the DSF agree well with the evidence from large scale experiments. ► Two expressions have been proposed to calculate DSF as a function of H{sub R}. ► The DSF may help in indicating the danger of ignition of a LNG vapor cloud. -- Abstract: The growing importance of liquefied natural gas (LNG) to global energy demand has increased interest in the possible hazards associated with its storage and transportation. Concerning the event of an LNG spill, a study was performed on the relationship between the distance at which the lower flammability limit (LFL) concentration occurs and that corresponding to the visible contour of LNG vapor clouds. A parameter called the dispersion safety factor (DSF) has been defined as the ratio between these two lengths, and two expressions are proposed to estimate it. During an emergency, the DSF can be a helpful parameter to indicate the danger of cloud ignition and flash fire.

  8. Fire performance of LNG carriers insulated with polystyrene foam.

    2008-10-30

    Analysis of the response of a liquid-full Moss Sphere LNG tank insulated with polystyrene foam to an engulfing LNG fire indicates that current regulatory requirements for pressure relief capacity sufficient to prevent tank rupture are inadequate. The inadequacy of the current requirements stems primarily from two factors. Firstly, the area of the Moss Sphere protruding above what would be the nominal deck on a conventional carrier, which is protected only by a steel weather cover from exposure to heat from a tank-engulfing fire, is being underestimated. Secondly, aluminum foil-covered polystyrene foam insulation applied to the exterior of the LNG tank is protected above the deck only by the steel weather cover under which the insulation could begin to melt in as little as 1-3 min, and could completely liquefy in as few as 10 min. U.S. and International Regulations require that the insulations on the above-deck portion of tanks have approved fire proofing and stability under fire exposure. Polystyrene foam, as currently installed on LNG carriers, does not appear to meet these criteria. As a result of these findings, but giving no consideration to the significant potential for further damage if the polystyrene should burn, the boil-off rate is predicted to be an order-of-magnitude higher than provided for by current PRV sizing requirements.

    Previous research suggests that high expansion foam with an expansion ratio of 500 to 1 is one of the best options for controlling liquefied natural gas (LNG) pool fire on land. However, its effectiveness heavily depends on the foam application rate, foam generator location, and the design of LNG spill containment dike. Examination of these factors is necessary to achieve the maximum benefit for applying HEX on LNG pool fires. While theoretical study of the effects of foam on LNG fires is important, the complicated phenomena involved in LNG pool fire and foam application increase the need for LNG field experimentation. Therefore, five LNG experiments were conducted at Texas A&M University's Brayton Fire Training Field. ANGUS FIRE provided Expandol solution to form 500 to 1 high expansion foam (HEX) and its latest LNG Turbex Fixed High Expansion Foam Generators. In this paper, data collected during five experiments are presented and analyzed. The effectiveness of high expansion foam for controlling LNG pool fires with various application rates at two different types of containment pits is discussed. LNG fire behaviors and the effects of dike wall height are also presented and discussed.

    2012-02-01

    A fast neutron facility provides a number of complexities in both detection and shielding, the latter arising not only due to uncertainty in the behaviour of the scattered radiation (neutron and gamma-rays) from a fast neutron source, but also on shielding requirements that have to take into account internal and external factors, such as dose limitations, space availability for implementing bulky shielding and secondary interactions of the radiation with materials. This has possible influence on experimental measurements with a low signal to noise ratio. This paper reports on some of the investigations performed at a RFQ accelerator facility generating > 1011 neutrons per second with energies up to 14 MeV, which are used to perform fast neutron radiography studies. Areas highlighted are the neutron cross section libraries, where important data needs to be reviewed or updated.

    Liquid natural gas (LNG) can provide plenty of cold energy when it is used as the fuel. The cold energy can be recovered and utilized in refrigerated track refrigeration. LNC refrigerated truck can effectively save energy and avoid the ozone layer depletion and greenhouse effect. Traditionally, cold energy is recovered after direct gasification of LNG, which is happened in cold energy recover heat exchanger. However, frost is easily formed in the heat exchanger surface in this system and cause the performance of heat exchanger to decline. This paper proposed a method, which heat pipe technology was used to recover the cold energy released by UVG and achieve refrigeration in refrigerated truck. Besides, a new type of heat - pipe - based heat exchanger for LNG cold energy recover was designed. The new type of heat exchanger has high efficiency and compact characteristic.%液化天然气(LNG)用做优质“绿色”汽车燃料的同时,还具有大量的冷能,该冷能可回收用于冷藏车制冷,LNG冷藏车是一种节能环保型汽车.在LNG冷藏车冷量回收系统中,传统的方式是将LNG在换热器中直接气化,并向空气释放冷量,但这种方式中的换热器表面易结霜,对其性能造成很大危害.文中提出了采用热管技术回收LNG冷量并用于冷藏车制冷的方法;设计了新型的热管式LNG冷量回收换热器,该新型换热器具有高效、紧凑等特点.

    Full Text Available The distribution of public facilities and their spatial equity is an important matter to be considered while planning public facilities. However, most of the studies in the literature have taken into consideration only a single type of facility while leaving other facilities unconsidered. In this paper an integrated spatial index for public facilities has been developed integrating GIS and spatial analysis models. The index measures the spatial equity based on the accessibility of 6 different types of public facilities for 5247 unions and 476 sub-districts of Bangladesh. Spatial autocorrelation techniques have been applied to understand the spatial pattern of accessibility. In fact it helps to understand the characteristics of spatial equity both for disaggregated and aggregated levels. It has been found that variation accessibilities to the facilities across the space are significant. Distribution of some facilities are spatially clustered to some particular areas means those areas are in an advantageous position in terms of accessibility while other areas are in a backward condition. The proposed index and the spatial autocorrelation will help to identify which areas should receive more priority in allocating particular types of public facilities in the future.

    Full Text Available Presentation is a powerful teaching tool. Every teacher would love to support his lecture with presentation aids. Even though these presentations are created using standalone tools likepresentation software, these presentations need to be archived for future retrieval. Till a few years ago faculty used to carry their presentations in the form of slides, which used to be cumbersome.Presentations using photographic slides were rigid offering no flexibility to the speaker. Now with the increasing use of computers and laptops digital presentations are becoming the order of the day.Today's teachers are expected to be comfortable with presentation software and their use. This study was performed to assess the awareness of faculty about online presentation archiving facilities. Questionnaires were used to elicit responses from faculty. This study revealed that only 10% of the faculty questioned knew about the online storage facilities and only 2% of them are regularly archiving their presentation. This study concludes that more needs to be done in creating awareness among faculty regarding online presentation storage facilites available.

  19. New spatial clustering-based models for optimal urban facility location considering geographical obstacles

    The problems of facility location and the allocation of demand points to facilities are crucial research issues in spatial data analysis and urban planning. It is very important for an organization or governments to best locate its resources and facilities and efficiently manage resources to ensure that all demand points are covered and all the needs are met. Most of the recent studies, which focused on solving facility location problems by performing spatial clustering, have used the Euclidean distance between two points as the dissimilarity function. Natural obstacles, such as mountains and rivers, can have drastic impacts on the distance that needs to be traveled between two geographical locations. While calculating the distance between various supply chain entities (including facilities and demand points), it is necessary to take such obstacles into account to obtain better and more realistic results regarding location-allocation. In this article, new models were presented for location of urban facilities while considering geographical obstacles at the same time. In these models, three new distance functions were proposed. The first function was based on the analysis of shortest path in linear network, which was called SPD function. The other two functions, namely PD and P2D, were based on the algorithms that deal with robot geometry and route-based robot navigation in the presence of obstacles. The models were implemented in ArcGIS Desktop 9.2 software using the visual basic programming language. These models were evaluated using synthetic and real data sets. The overall performance was evaluated based on the sum of distance from demand points to their corresponding facilities. Because of the distance between the demand points and facilities becoming more realistic in the proposed functions, results indicated desired quality of the proposed models in terms of quality of allocating points to centers and logistic cost. Obtained results show promising

    Prospects for export of liquified natural gas (LNG) from Alaska's North Slope are assessed. Projected market conditions to 2010 show that new LNG capacity beyond announced expansions will be needed to meet regional demand and that supplies will probably come from outside the region. The estimated delivered costs of likely suppliers show that Alaska North Slope gas will not be competitive. The alternative North Slope gas development strategies of transport and sale to the lower 48 states and use on the North Slope for either enhanced oil recovery or conversion to liquids are examined. The alternative options require delaying development until US gas prices increase, exhaustion of certain North Slope oil fields, or advances occur in gas to liquid fuels conversion technology. ?? 1995.

  1. CFD Modeling of LNG Spill: Humidity Effect on Vapor Dispersion

    2015-09-01

    The risks entailed by an accidental spill of Liquefied Natural Gas (LNG) should be indentified and evaluated, in order to design measures for prevention and mitigation in LNG terminals. For this purpose, simulations are considered a useful tool to study LNG spills and to understand the mechanisms that influence the vapor dispersion. In the present study, the ADREA-HF CFD code is employed to simulate the TEEX1 experiment. The experiment was carried out at the Brayton Fire Training Field, which is affiliated with the Texas A&M University system and involves LNG release and dispersion over water surface in open- obstructed environment. In the simulation the source was modeled as a two-phase jet enabling the prediction of both the vapor dispersion and the liquid pool spreading. The conservation equations for the mixture are solved along with the mass fraction for natural gas. Due to the low prevailing temperatures during the spill ambient humidity condenses and this might affect the vapor dispersion. This effect was examined in this work by solving an additional conservation equation for the water mass fraction. Two different models were tested: the hydrodynamic equilibrium model which assumes kinetic equilibrium between the phases and the non hydrodynamic equilibrium model, in order to assess the effect of slip velocity on the prediction. The slip velocity is defined as the difference between the liquid phase and the vapor phase and is calculated using the algebraic slip model. Constant droplet diameter of three different sizes and a lognormal distribution of the droplet diameter were applied and the results are discussed and compared with the measurements.

  2. Analysis of temperature and pressure changes in liquefied natural gas (LNG) cryogenic tanks

    Liquefied natural gas (LNG) is being developed as a transportation fuel for heavy vehicles such as trucks and transit buses, to lessen the dependency on oil and to reduce greenhouse gas emissions. The LNG stations are properly designed to prevent the venting of natural gas (NG) from LNG tanks, which can cause evaporative greenhouse gas emissions and result in fluctuations of fuel flow and changes of fuel composition. Boil-off is caused by the heat added into the LNG fuel during the storage and fueling. Heat can leak into the LNG fuel through the shell of tank during the storage and through hoses and dispensers during the fueling. Gas from tanks onboard vehicles, when returned to LNG tanks, can add additional heat into the LNG fuel. A thermodynamic and heat transfer model has been developed to analyze different mechanisms of heat leak into the LNG fuel. The evolving of properties and compositions of LNG fuel inside LNG tanks is simulated. The effect of a number of buses fueled each day on the possible total fuel loss rate has been analyzed. It is found that by increasing the number of buses, fueled each day, the total fuel loss rate can be reduced significantly. It is proposed that an electric generator be used to consume the boil-off gas or a liquefier be used to re-liquefy the boil-off gas to reduce the tank pressure and eliminate fuel losses. These approaches can prevent boil-off of natural gas emissions, and reduce the costs of LNG as transportation fuel.

    A novel method for fabrication of superhydrophobic surfaces was developed by facile coating various metal oxide nanoparticles, including ZnO, Al2O3 and Fe3O4, on various substrates followed by treatment with polydimethylsiloxane (PDMS) via chemical vapor deposition (CVD) method. Using ZnO nanoparticles as a model, the changes in the surface chemical composition and crystalline structures of the metal oxide nanoparticles by PDMS treatment were investigated by X-ray photoelectron spectroscopy (XPS), X-ray powder diffraction (XRD) and Fourier transform infrared (FTIR) analysis. The results show that the combination of the improved surface roughness generated from of the nanoparticles aggregation with the low surface-energy of silicon-coating originated from the thermal pyrolysis of PDMS would be responsible for the surface superhydrophobicity. By a simple dip-coating method, we show that the metal oxide nanoparticles can be easily coated onto the surfaces of various textural and dimensional substrates, including glass slide, paper, fabric or sponge, for preparation of superhydrophobic surfaces for different purpose. The present strategy may provide an inexpensive and new route to surperhydrophobic surfaces, which would be of technological significance for various practical applications especially for separation of oils or organic contaminates from water.

The increasing of Malaysian population brought many problems to the environment especially traffic congestion problem. The Government spends a lot of money to overcome this problem [10]. Public transport has been upgraded to ensure user comfort. Most people in the city are more interested in using railway transport as traffic congestion and travel time accuracy is better than other public transport [1, 5]. To influence public demand, the facilities available at the train station should be complete [3, 5]. The choice of location for the study are Batu Gajah station (station 1 and Kluang station (station 2 for rural services while Bandar Tasik Selatan station (station 3 and KL Central station (station 4 for urban services. The results of this study showed that, based on data and information obtained from field survey work and the feedback questionnaires from users, basic facilities at railway stations surveyed for urban and rural services can be identified and listed. An analysis of the status of the facilities at railway stations can be established through the safety of passengers and observations in the field. The facilities available at the urban service station are more complete than in rural service station. Facilities at railway station should be improved to attract people using the facilities.

  16. Analysis of Hanford-based Options for Sustainable DOE Facilities on the West Coast

    Energy Technology Data Exchange (ETDEWEB)

    Warwick, William M.

    2012-06-30

    Large-scale conventional energy projects result in lower costs of energy (COE). This is true for most renewable energy projects as well. The Office of Science is interested in its facilities meeting the renewable energy mandates set by Congress and the Administration. Those facilities on the west coast include a cluster in the Bay Area of California and at Hanford in central Washington State. Land constraints at the California facilities do not permit large scale projects. The Hanford Reservation has land and solar insolation available for a large scale solar project as well as access to a regional transmission system that can provide power to facilities in California. The premise of this study is that a large-scale solar project at Hanford may be able to provide renewable energy sufficient to meet the needs of select Office of Science facilities on the west coast at a COE that is competitive with costs in California despite the lower solar insolation values at Hanford. The study concludes that although the cost of solar projects continues to decline, estimated costs for a large-scale project at Hanford are still not competitive with avoided power costs for Office of Science facilities on the west coast. Further, although it is possible to transmit power from a solar project at Hanford to California facilities, the costs of doing so add additional costs. Consequently, development of a large- scale solar project at Hanford to meet the renewable goals of Office of Science facilities on the west coast is currently uneconomic. This may change as solar costs decrease and California-based facilities face increasing costs for conventional and renewable energy produced in the state. PNNL should monitor those cost trends.

    The operation to Liquefied Natural Gas (LNG) is innovative for the PETROBRAS System. PETROBRAS Transporte - TRANSPETRO will operate two LNG flexible terminals. In accordance with the health, safety and environmental policy - training, education and awareness action plans were formulated by TRANSPETRO to assure the operational safety for the activity. Part of this action plan includes the training of LNG spill control and fire suppression. The training was carried out in 20 hours and divided into two parts: theoretical and practice.

    A large portion of world's natural gas reserves are "stranded" resources, the drive to monetize these resources leads to the development of gas-to-liquids (GTL) and liquefied natural gas (LNG) technologies. LNG has the advantage of having been developed for the past 40 years and having an excellent safety record. GTL on the other hand is another option with substantial benefits, but its development stage and commercial viability are far behind LNG. This paper presents a techno-economic comparison of GTL with LNG, including technical development, plant efficiency, market potential for the products, and capital cost for the infrastructure. The aim is to give an overall view on both LNG and GTL and provide a perspective on the profitability of these two technologies.

    The flow area and volume are scaled down to 1/49. The ratio of the hydraulic diameter is 1/7. Therefore, SMART-ITL is a large-scale thermalhydraulic test facility with about 45 m height, which is consisted of 10 m underground and 35 m from the ground level. Until now, the management of design data and maintenance of large scale test facilities have been managed based on hard-copy information. Recently, Thermal Hydraulics Safety Research Division (THSRD) at Korea Atomic Energy Research Institute (KAERI) has developed Facility Management System (FMS) based Building Information Modeling (BIM) to manage its design data more effectively for these large scale test facilities of SMART-ITL and ATLAS, and this BIM technology has been applied to SMART-ITL at the first. This study proposed a method of effective management and maintenance of design data applied to the SMART-ITL. That is, a FMS was developed based on the BIM technology for SMART-ITL. Figure 2 shows an overview of FMS development process based on BIM technology. SMART-ITL FMS facilitates its management and maintenance more effectively and accurately by 3- dimensional visualization. It enables the shape information of large scale test facilities to be visualized intuitively in a virtual space, and the efficient maintenance of data and instruments is possible by linking 3D shape information.

    2016-01-01

    Full Text Available The World market of liquefied natural gas (LNG is growing rapidly. In 2015 LNG production exceeded 333 bcm with its predicted increase up to 450 bcm in 2019. The analysis of LNG role in natural gas import to the EU in recent years shows variability: LNG share in overall import reached 25% in 2011 and it went down to 15% in 2014. The smaller demand for natural gas including LNG in the EU can be due to, among others, a slower economic growth and a dynamic development of the use of renewable energy sources. The article shows the role of natural gas in the structure of consumption of primary energy as well as the changes in demand for natural gas in the years 2007–2014 for the main groups of end users: industry, energy production and individual households. The biggest fall in demand for natural gas has been observed in energy production sector in recent years. This publication continues to analyse the structure of natural gas supplies to the EU, with special emphasis on the directions of LNG import to the countries such as: The UK, Spain, France, Greece, Belgium, Portugal, Italy, Lithuania and The Netherlands. The significance of LNG in the balance of consumption of natural gas in these countries has been presented as well as the infrastructure connected with LNG and plans of development of regasification terminals. In the summary the most important conclusions have been drawn and a chance of the increase in significance of the role of LNG in the balance of natural gas supplies has been pointed out, which is due to the steep fall of LNG prices which has taken place in recent years.

    2011-01-01

    The present building facility management status in China resulted in many problems such as highenergy consumption, failure of automation control, services failure and poor indoor air quality. Based onquestionnaires and interviews to professional engineers and building users, a comprehensive evaluation index system was established on facility management of high-rise office buildings. A Fuzzy AHP based upon hierarchy criteria system was established. A Fuzzy AHP Evaluation Model on Facility Management System was set up ;α-cut analysis was introduced and incorporated with expert knowledge together, which made up the optimism index λ. The fuzzy optimum crisp weight of each criterion was resulted from data-mining. Case investigations were processed in high-rise office buildings in Shenyang. The results illustrated that indoor air quality, thermal comfort and life cycle cost were the most important indexes in the evaluation of Facility Management System of high rise office buildings. Residents in high-rise buildings in Shenyang pay less attention to maintenance management and environment protection. By comparison with the analysis result of Export Choice, Fuzzy AHP-based evaluation model could act as a scientific reference for the establishment of governmental standards in facility management area in building.

    A computer-aided method to design a hybrid layout-tree-shape planar flowlines is presented. In new-type flowshop layout, the common machines shared by several flowlines could be located together in functional sections. The approach combines traditional cell formation techniques with sequence alignment algorithms. Firstly, a sequence analysis based cell formation procedure is adopted; then the operation sequences for parts are aligned to maximize machines adjacency in hyperedge representations; finally a tree-shape planar flowline will be obtained for each part family. With the help of a sample of operation sequences obtained from industry, this algorithm is illustrated.

    Research and development work is currently in progress in France on the feasibility of transmutation of very long-lived radionuclides such as americium, blended with an inert medium such as magnesium oxide and pelletized for irradiation in a fast neutron reactor. The process is primarily designed to produce ceramics for nuclear reactors, but could also be used to produce targets for accelerators. The Actinide Development Laboratory is part of the ATALANTE complex at Marcoule, where the CEA investigates reprocessing, liquid and solid waste treatment and vitrification processes. The laboratory produces radioactive sources; after use, their constituents are recycled, notably through R and D programs requiring such materials. Recovered americium is purified, characterized and transformed for an experiment known as ECRIX, designed to demonstrate the feasibility of fabricating americium-based ceramics and to determine the reactor transmutation coefficients.

    The discovery that the neutrino changes flavor as it travels through space has implications for the Standard Model of particle physics (SM)[1]. To know the contribution of neutrinos to the SM, needs precise measurements of the parameters governing the neutrino oscillations. This will require a high intensity beam-based neutrino oscillation facility. The EURONu Design Study will review three currently accepted methods of realizing this facility (the so-called Super-Beams, Beta Beams and Neutrino Factories) and perform a cost assessment that, coupled with the physics performance, will give means to the European research authorities to make a decision on the layout and construction of the future European neutrino oscillation facility. ”Beta Beams” produce collimated pure electron neutrino and antineutrino beams by accelerating beta active ions to high energies and letting them decay in a race-track shaped storage ring.

    Current Department of Energy criteria for facilities subjected to natural hazards provide guidelines to place facilities or portions of facilities into usage categories. Usage categories are based on characteristics such as mission dependence, type of hazardous materials involved, and performance goals. Seismic requirements are significantly more stringent for facilities falling into higher ``hazard facility use categories``. A special problem arises in cases where a facility or portion of a facility is dependent on another facility of lower ``hazard facility use category`` for support or protection. Creative solutions can minimize the cost Unpact of ensuring that the lower category item does not compromise the performance of the higher category item. In this paper, a base isolation solution is provided for a ``low hazard facility use category`` weather enclosure designed so it will not collapse onto a ``high hazard facility use category`` high level waste storage facility at INEL. This solution is compared to other more conventional procedures. Details, practical limitations, licensing and regulatory considerations, and cost comparisons are provided.

    2016-10-01

    Full Text Available The cryogenic hydraulic turbine can be used to replace the conventional J–T valve for LNG or mixed refrigerant throttling and depressurization in a natural gas liquefaction plant. This advanced technology is not only to enhance the efficiency of the liquefaction plant, but to usher a new trend in the development of global liquefaction technologies. China has over 136 liquefaction plants, but the cryogenic hydraulic turbines have not been deployed in industrial utilization. In addition, these turbines cannot be manufactured domestically. In this circumstance, through working on the key technologies for LNG hydraulic turbine process & control system development, hydraulic model optimization design, structure design and manufacturing, the first domestic cryogenic hydraulic turbine with a flow rate of 40 m3/h was developed to recover the pressure energy from the LNG of cold box. The turbine was installed in the CNOOC Zhuhai Natural Gas Liquefaction Plant for industrial tests under multiple working conditions, including start-stop, variable flow rates and variable rotation speeds. Test results show that the domestic LNG cryogenic hydraulic turbine has satisfactory mechanical and operational performances at low temperatures as specified in design. In addition, the process & control system and frequency-conversion power-generation system of the turbine system are designed properly to automatically and smoothly replace the existing LNG J–T valve. As a result, the domestic LNG cryogenic hydraulic turbine system can improve LNG production by an average of 2% and generate power of 8.3 kW.

    Full Text Available The objective of this present study is to propose an approach to predict mass transfer time relaxation parameter for boiling simulation on the shell-side of LNG spiral wound heat exchanger (SWHE. The numerical model for the shell-side of LNG SWHE was established. For propane and ethane, a predicted value of mass transfer time relaxation parameter was presented through the equivalent evaporation simulations and was validated by the Chisholm void fraction correlation recommended under various testing conditions. In addition, heat transfer deviations between simulations using the predicted value of mass transfer time relaxation parameter and experiments from Aunan were investigated. The boiling characteristics of SWHE shell-side were also visualized based on the simulations with VOF model. The method of predicting mass transfer time relaxation parameter may be well applicable to various phase change simulations.

    This work aims analyze the constraints to the introduction of LNG in the Brazilian energy matrix. Therefore, considers the current regulatory framework and the investments recently made by PETROBRAS to acquire LNG in the international market in order to supply power plants in the country. In order to assess the current status of the LNG plants in the electricity sector, factors are analyzed in terms of the natural gas industry and electric power industry, such as: storage, LNG contracts, operating dispatch, LNG plants pricing and operational flexibility. Despite the increase in LNG international trade and the prospect of using this product in Brazil, there are some challenges for the effective use of LNG plants by Brazilian electric sector. Some of the challenges are the need to review the methodology of calculating the cost benefit of LNG power plants. Another important challenge is to examine the use of underground storage and its influence in the operating dispatch of LNG plants. (author)

    The Space Power Facility at NASA's Plum Brook Station houses the world's largest and most powerful space environment simulation facilities, including the Mechanical Vibration Facility (MVF), which offers the world's highest-capacity multi-axis spacecraft shaker system. The MVF was designed to perform sine vibration testing of a Crew Exploration Vehicle (CEV)-class spacecraft with a total mass of 75,000 pounds, center of gravity (cg) height above the table of 284 inches, diameter of 18 feet, and capability of 1.25 gravity units peak acceleration in the vertical and 1.0 gravity units peak acceleration in the lateral directions. The MVF is a six-degree-of-freedom, servo-hydraulic, sinusoidal base-shake vibration system that has the advantage of being able to perform single-axis sine vibration testing of large structures in the vertical and two lateral axes without the need to reconfigure the test article for each axis. This paper discusses efforts to extend the MVF's capabilities so that it can also be used to determine fixed base modes of its test article without the need for an expensive test-correlated facility simulation.

    A facility-based protein crystallization apparatus for microgravity (PCAM) has been constructed and flown on a series of Space Shuttle Missions. The hardware development was undertaken largely because of the many important examples of quality improvements gained from crystal growth in the diffusion-limited environment in space. The concept was based on the adaptation for microgravity of a commonly available crystallization tray to increase sample density, to facilitate co-investigator participation and to improve flight logistics and handling. A co-investigator group representing scientists from industry, academia, and government laboratories has been established. Microgravity applications of the hardware have produced improvements in a number of structure-based crystallographic studies and include examples of enabling research. Additionally, the facility has been used to support fundamental research in protein crystal growth which has delineated factors contributing to the effect of microgravity on the growth and quality of protein crystals.

    This study has provided an initial picture of where the most interesting ports and areas available for future expansion of a maritime infrastructure for LNG. On the basis of supplying vessels with LNG as fuel, from a long term perspective, we recommend locating LNG terminals in or near major ports and around the big ship routes. Given the current age distribution of ships operating waters of the Baltic Sea, almost 20% of the vessels are 30-40 years old and likely to be replaced by 2015 - 2020. Thus, there is a potential for newly built ships will be equipped with LNG operation. Selected criteria s; Size of the LNG terminal and hence the need for the size of the fairway and the area of land. Proximity to traffic routes with much ship traffic. Proximity to the major port. Proximity to consumers on the land side. On the basis of selected criteria and analyzed for possible location of the terminal it can be noted that a number of Swedish ports are found suitable. For example, ports of Sundsvall, Gothenburg and Helsingborg has been identified as suitable, but with different starting point and different types and sizes of terminals possible.

  11. Boil-off gas vapors are recovered by reliquefaction in LNG

    1986-02-24

    Although great care is taken to prevent heat leaks into cryogenic equipment in LNG terminals, boil-off vapors evolve from LNG stored at thermodynamic equilibrium. The quantities of boil-off vapors may be quite considerable. They account for about 1% of the total gas quantity received and sent out at the monitor-de-bretagne LNG terminal of Gaz de France. A novel process has significantly cut boil-off vapor handling costs. It is free of technical problems which would arise from local utilization of the gas and makes boil-off recovery possible under optimum conditions. In addition, the process shows an excellent degree of reliability. Boil-off vapors have a lower heating value than the stored LNG. However, since they mainly consist of methane, their economic usefulness makes vapor recovery necessary. This boil-off gas, with widely fluctuating quantities and qualities, cannot be readily used locally. The vapors must be sent out into the grid.

    The levonorgestrel-releasing intrauterine system (LNG-IUS) is effective in the treatment of dysmenorrhea associated with adenomyosis. However, the mechanism of pain relief of LNG-IUS in patients with adenomyosis is unclear. We aimed to investigate the effects of LNG-IUS on the expression of nerve growth factor (NGF) and its receptors, NGFR p75 and TrkA in patients with adenomyosis. Endometrial and myometrial tissues were prepared from 17 LNG-IUS-treated patients and 15 hormonally untreated patients who had undergone hysterectomies for adenomyosis. Immunohistochemistry with antibodies against NGF, NGFR p75, and TrkA, was performed. The expression of NGF, NGFR p75, and TrkA in endometrium and myometrium of LNG-IUS-treated patients was significantly decreased compared to those of hormonally untreated patients. Our findings may indicate that the suppression of NGF and its receptors by LNG-IUS is another possible mechanism of relieving pain in patients with adenomyosis.

    Facility management (FM) has become an important topic in research on the operation and maintenance phase. Managing the work of FM effectively is extremely difficult owing to the variety of environments. One of the difficulties is the performance of two-dimensional (2D) graphics when depicting facilities. Building information modeling (BIM) uses precise geometry and relevant data to support the facilities depicted in three-dimensional (3D) object-oriented computer-aided design (CAD). This paper proposes a new and practical methodology with application to FM that uses an integrated 2D barcode and the BIM approach. Using 2D barcode and BIM technologies, this study proposes a mobile automated BIM-based facility management (BIMFM) system for FM staff in the operation and maintenance phase. The mobile automated BIMFM system is then applied in a selected case study of a commercial building project in Taiwan to verify the proposed methodology and demonstrate its effectiveness in FM practice. The combined results demonstrate that a BIMFM-like system can be an effective mobile automated FM tool. The advantage of the mobile automated BIMFM system lies not only in improving FM work efficiency for the FM staff but also in facilitating FM updates and transfers in the BIM environment.

    2008-09-01

    One of the basic facilities at the Joint Institute for Nuclear Research (JINR) in Dubna is the 6 A GeV Nuclotron, which has replaced the old weak focusing 10-GeV proton accelerator Synchrophasotron. The first relativistic nuclear beams with the energy of 4.2 A GeV were obtained at the Synchrophasotron in 1971. Since that time, relativistic nuclear physics has been one of the main directions of the JINR research program. In the coming years, the new JINR flagship program assumes the experimental study of hot and dense strongly interacting QCD matter at the new JINR facility. This goal is proposed to be reached by (i) development of the existing Nuclotron accelerator facility as a basis for generation of intense beams over atomic mass range from protons to uranium and light polarized ions, (ii) design and construction of the Nuclotron-based heavy Ion Collider fAcility (NICA) with the maximum nucleon-nucleon center-of-mass collision energy of √ s NN = 9 GeV and averaged luminosity 1027 cm-2 s-1, and (iii) design and construction of the Multipurpose Particle Detector (MPD) at intersecting beams. Realization of the project will lead to unique conditions for research activity of the world community. The NICA energy region is of major interest because the highest nuclear (baryonic) density under laboratory conditions can be reached there. Generation of intense polarized light nuclear beams aimed at investigation of polarization phenomena at the Nuclotron is foreseen.

    The aim of the Gemini Observatory's Base Facilities Project is to provide the capabilities to perform routine night time operations with both telescopes and their instruments from their respective base facilities without anyone present at the summit. Tightening budget constraints prompted this project as both a means to save money and an opportunity to move toward increasing remote operations in the future. We successfully moved Gemini North nighttime operation to our base facility in Hawaii in Nov., 2015. This is the first 8mclass telescope to completely move night time operations to base facility. We are currently working on implementing BFO to Gemini South. Key challenges for this project include: (1) This is a schedule driven project. We have to implement the new capabilities by the end of 2015 for Gemini North and end of 2016 for Gemini South. (2) The resources are limited and shared with operations which has the higher priority than our project. (3) Managing parallel work within the project. (4) Testing, commissioning and introducing new tools to operational systems without adding significant disruptions to nightly operations. (5) Staff buying to the new operational model. (6) The staff involved in the project are spread on two locations separated by 10,000km, seven time zones away from each other. To overcome these challenges, we applied two principles: "Bare Minimum" and "Gradual Descent". As a result, we successfully completed the project ahead of schedule at Gemini North Telescope. I will discuss how we managed the cultural and human aspects of the project through these concepts. The other management aspects will be presented by Gustavo Arriagada [2], the Project Manager of this project.

    Federal safety regulations require the use of validated consequence models to determine the vapor cloud dispersion exclusion zones for accidental liquefied natural gas (LNG) releases. One tool that is being developed in industry for exclusion zone determination and LNG vapor dispersion modeling is computational fluid dynamics (CFD). This paper uses the ANSYS CFX CFD code to model LNG vapor dispersion in the atmosphere. Discussed are important parameters that are essential inputs to the ANSYS CFX simulations, including the atmospheric conditions, LNG evaporation rate and pool area, turbulence in the source term, ground surface temperature and roughness height, and effects of obstacles. A sensitivity analysis was conducted to illustrate uncertainties in the simulation results arising from the mesh size and source term turbulence intensity. In addition, a set of medium-scale LNG spill tests were performed at the Brayton Fire Training Field to collect data for validating the ANSYS CFX prediction results. A comparison of test data with simulation results demonstrated that CFX was able to describe the dense gas behavior of LNG vapor cloud, and its prediction results of downwind gas concentrations close to ground level were in approximate agreement with the test data.

    Ports act as essential hubs in the global economy. But the rise in maritime traffic is taking a toll on the quality of air in ports and out at sea. From 2015 onwards, threshold governing harmful emissions are being tightened in a bid to clear the air. All of which is driving interest in more environmentally sound fuels. Liquefied natural gas (LNG) is the perfect fit, more than complying with the upcoming regulations. To enable its widespread adoption, Linde is working full steam ahead to create a network of LNG terminals in Europe. (orig.)

    The increase in demand for natural gas in the world, cause that the production of liquefied natural gas (LNG) and in consequences its regasification becoming more common process related to its transportation. Liquefied gas is transported in the tanks at a temperature of about 111K at atmospheric pressure. The process required to convert LNG from a liquid to a gas phase for further pipeline transport, allows the use of exergy of LNG to various applications, including for electricity generation. Exergy analysis is a well known technique for analyzing irreversible losses in a separate process. It allows to specify the distribution, the source and size of the irreversible losses in energy systems, and thus provide guidelines for energy efficiency. Because both the LNG regasification and liquefaction of natural gas are energy intensive, exergy analysis process is essential for designing highly efficient cryogenic installations. Wzrost zapotrzebowania na gaz ziemny na świecie powoduje, że produkcja skroplonego gazu ziemnego (LNG), a w konsekwencji jego regazyfikacja, staje się coraz bardziej powszechnym procesem związanym z jego transportem. Skroplony gaz transportowany jest w zbiornikach w temperaturze około 111K pod ciśnieniem atmosferycznym. Przebieg procesu regazyfikacji niezbędny do zamiany LNG z fazy ciekłej w gazową dla dalszego transportu w sieci, umożliwia wykorzystanie egzergii LNG do różnych zastosowań, między innymi do produkcji energii elektrycznej. Analiza egzergii jest znaną techniką analizowania nieodwracalnych strat w wydzielonym procesie. Pozwala na określenie dystrybucji, źródła i wielkości nieodwracalnych strat w systemach energetycznych, a więc ustalić wytyczne dotyczące efektywnego zużycia energii. Ponieważ zarówno regazyfikacja LNG jak i skraplanie gazu ziemnego są energochłonne, proces analizy egzergii jest niezbędny do projektowania wysoce wydajnych instalacji kriogenicznych.

    This study set the pyroprocess facility at an engineering scale as a cost object, and presented the cost consumed during the unit processes of the pyroprocess. For the cost calculation, the activity based costing (ABC) method was used instead of the engineering cost estimation method, which calculates the cost based on the conceptual design of the pyroprocess facility. The calculation results demonstrate that the pyroprocess facility's unit process cost is $194/kgHM for pretreatment, $298/kgHM for electrochemical reduction, $226/kgHM for electrorefining, and $299/kgHM for electrowinning. An analysis demonstrated that the share of each unit process cost among the total pyroprocess cost is as follows: 19% for pretreatment, 29% for electrochemical reduction, 22% for electrorefining, and 30% for electrowinning. The total unit cost of the pyroprocess was calculated at $1,017/kgHM. In the end, electrochemical reduction and the electrowinning process took up most of the cost, and the individual costs for these two processes was found to be similar. This is because significant raw material cost is required for the electrochemical reduction process, which uses platinum as an anode electrode. In addition, significant raw material costs are required, such as for Li3PO4, which is used a lot during the salt purification process.

    A risk-based logic model is suggested as an appropriate basis for better predicting accident progression and ensuing source terms to the environment from process upset conditions in complex chemical process facilities. Under emergency conditions, decision-makers may use the Accident Progression Event Tree approach to identify the best countermeasure for minimizing deleterious consequences to receptor groups before the atmospheric release has initiated. It is concluded that the chemical process industry may use this methodology as a supplemental information provider to better comply with the Environmental Protection Agency`s proposed 40 CFR 68 Risk Management Program rule. An illustration using a benzene-nitric acid potential interaction demonstrates the value of the logic process. The identification of worst-case releases and planning for emergency response are improved through these methods, at minimum. It also provides a systematic basis for prioritizing facility modifications to correct vulnerabilities.

    Full Text Available Abstract Background High throughput gene expression profiling (GEP is becoming a routine technique in life science laboratories. With experimental designs that repeatedly span thousands of genes and hundreds of samples, relying on a dedicated database infrastructure is no longer an option. GEP technology is a fast moving target, with new approaches constantly broadening the field diversity. This technology heterogeneity, compounded by the informatics complexity of GEP databases, means that software developments have so far focused on mainstream techniques, leaving less typical yet established techniques such as Nylon microarrays at best partially supported. Results MAF (MicroArray Facility is the laboratory database system we have developed for managing the design, production and hybridization of spotted microarrays. Although it can support the widely used glass microarrays and oligo-chips, MAF was designed with the specific idiosyncrasies of Nylon based microarrays in mind. Notably single channel radioactive probes, microarray stripping and reuse, vector control hybridizations and spike-in controls are all natively supported by the software suite. MicroArray Facility is MIAME supportive and dynamically provides feedback on missing annotations to help users estimate effective MIAME compliance. Genomic data such as clone identifiers and gene symbols are also directly annotated by MAF software using standard public resources. The MAGE-ML data format is implemented for full data export. Journalized database operations (audit tracking, data anonymization, material traceability and user/project level confidentiality policies are also managed by MAF. Conclusion MicroArray Facility is a complete data management system for microarray producers and end-users. Particular care has been devoted to adequately model Nylon based microarrays. The MAF system, developed and implemented in both private and academic environments, has proved a robust solution for

    2013-01-01

    In light of the recent European developments in ion beam therapy, there is a strong interest from the biomedical research community to have more access to clinically relevant beams. Beamtime for pre-clinical studies is currently very limited and a new dedicated facility would allow extensive research into the radiobiological mechanisms of ion beam radiation and the development of more refined techniques of dosimetry and imaging. This basic research would support the current clinical efforts of the new treatment centres in Europe (for example HIT, CNAO and MedAustron). This paper presents first investigations on the feasibility of an experimental biomedical facility based on the CERN Low Energy Ion Ring LEIR accelerator. Such a new facility could provide beams of light ions (from protons to neon ions) in a collaborative and cost-effective way, since it would rely partly on CERN’s competences and infrastructure. The main technical challenges linked to the implementation of a slow extraction scheme for LEIR an...

    Facility maintenance management (FMM) has become an important topic for research on the operation phase of the construction life cycle. Managing FMM effectively is extremely difficult owing to various factors and environments. One of the difficulties is the performance of 2D graphics when depicting maintenance service. Building information modeling (BIM) uses precise geometry and relevant data to support the maintenance service of facilities depicted in 3D object-oriented CAD. This paper proposes a new and practical methodology with application to FMM using BIM technology. Using BIM technology, this study proposes a BIM-based facility maintenance management (BIMFMM) system for maintenance staff in the operation and maintenance phase. The BIMFMM system is then applied in selected case study of a commercial building project in Taiwan to verify the proposed methodology and demonstrate its effectiveness in FMM practice. Using the BIMFMM system, maintenance staff can access and review 3D BIM models for updating related maintenance records in a digital format. Moreover, this study presents a generic system architecture and its implementation. The combined results demonstrate that a BIMFMM-like system can be an effective visual FMM tool.

    Nanonization strategies have been used to enhance the oral availability of numerous drugs that are poorly soluble in water. Exploring a facile nanonization strategy with highly practical potential is an attractive focus. Here, we report a novel facile nanoaggregation strategy for constructing drug nanoparticles of poorly soluble drugs with pH-dependent solubility by utilizing acid-base neutralization in aqueous solution, thus facilitating the exploration of nanonization in oral delivery for general applicability. We demonstrate that hydrophobic itraconazole dissolved in acid solution formed a growing core and aggregated into nanoparticles in the presence of stabilizers. The nanoparticles, with an average diameter of 279.3 nm and polydispersity index of 0.116, showed a higher dissolution rate when compared with the marketed formulation; the average dissolution was about 91.3%. The in vivo pharmacokinetic studies revealed that the nanoparticles had a rapid absorption and enhanced oral availability. The diet state also showed insignificant impact on the absorption of itraconazole from nanoparticles. This nanoaggregation strategy is a promising nanonization method with a facile process and avoidance of toxic organic solvents for oral delivery of poorly soluble drugs with pH-dependent solubility and reveals a highly practical potential in the pharmaceutical and chemical industries.

    Neutron generators based on inertial electrostatic confinement fusion were considered for the design of a neutron irradiation facility for explanted organ Boron Neutron Capture Therapy (BNCT) that could be installed in a health care center as well as in research areas. The chosen facility configuration is "irradiation chamber", a ~20×20×40 cm(3) cavity near or in the center of the facility geometry where samples to be irradiated can be placed. Neutron flux calculations were performed to study different manners for improving scattering processes and, consequently, optimize neutron flux in the irradiation position. Flux distributions were assessed through numerical simulations of several models implemented in MCNP5 particle transport code. Simulation results provided a wide spectrum of combinations of net fluxes and energy spectrum distributions. Among them one can find a group that can provide thermal neutron fluxes per unit of production rate in a range from 4.1·10(-4) cm(-2) to 1.6·10(-3) cm(-2) with epithermal-to-thermal ratios between 0.3% and 13% and fast-to-thermal ratios between 0.01% to 8%. Neutron generators could be built to provide more than 10(10) n s(-1) and, consequently, with an arrangement of several generators appropriate enough neutron fluxes could be obtained that would be useful for several BNCT-related irradiations and, eventually, for clinical practice.
