The paper briefly reviews the technology, gas turbine versus high speed electric drive, which represents two very different solutions for natural gas pipeline or storage compressor drive applications. The technical and economic merits of the competing drive systems have to be considered for each individual project. Traditionally, gas turbines have been the prime drivers for compressor trains, especially in Europe whereas in North America gas engine driven reciprocating compressors are also very common. With the liberalization of the electric power market and tighter environmental restrictions regarding local emissions, high frequency electric motor drivers became a competitive alternative profiting by decreased costs for the electricity infrastructure and the power supply, thus lowering the investment and operational costs. Gas turbines in compliance with the latest emission regulations will maintain their predominant role in natural gas pipeline and storage applications, especially in non-residential and remote areas.

Remarkable Reduction

Low Frequency Noise at Gas Turbines A natural gas compressor station that was equipped with Hispano Suiza Turbines THM 1202 emitted high intensity noise between 20 Hz and 40 Hz, causing window vibrations and standing waves within the living rooms of a nearby residential area. Since additional sound attenuation by increasing the volume of the exhaust silencers was impossible, further investigations were carried out to explain the mechanism of this low frequency noise emission. By changing the flame pattern inside the combustion chambers of the turbines it was possible to achieve a remarkable reduction at 31.5 Hz amounting to 15 dB. The investigation procedure leading to the final results will be the subject of this presentation.

Carbon Dioxide Co2

The deployment of small gas turbines at landfills and wastewater treatment plants is attractive due to the availability of waste fuel gases generated at these sites and the need for onsite power and/or heat. The fuel gases produced by these applications typically contain 35 to 75% of the heating value of natural gas and contain methane (CH4) diluted primarily with carbon dioxide (CO2) and sometimes nitrogen (N2). Demonstrations of 30 to 250 kW gas turbines operating on these waste fuels are underway, but little detailed information on the systematic effect of the gas composition on performance is available. Growth in the use of small gas turbines for these applications will likely require that they meet increasingly stringent emission regulations, creating a need to better understand and to further optimize emissions performance for these gases. The current study characterizes a modified commercial natural gas fired 60 kW gas turbine operated on simluated gases of specified composition and establishes a quantitative relationship between fuel composition, engine load, and emissions performance. The results can be used to determine the expected impact of gas composition on emissions performance.

Im Zuge der Bewertungen zum Stand der Lärmminderungstechnik sind sowohl detaillierte Untersuchungen an den einzelnen Schallquellen als auch die Messung und Berechnung der vorhandenen Geräuschimmissionsbeiträge nötig. Wird die Untersuchung nach vorstehend beschriebener Methodik vollzogen, kann eine abschließende Prüfung erfolgen, da sowohl die derzeitige Geräuschsituation im Umfeld einer Anlage bekannt ist, als auch Kenntnisse darüber erlangt werden, mit welchem Aufwand ggf. zusätzliche Minderungen der Geräuschsituation erreicht werden können. Wesentlich ist dabei die Bewertung der Verhältnismäßigkeit. Wird zudem ein geeignetes Abschneidekriterium gewählt, ist der entstehende Aufwand selbst bei großen Industriestandorten noch vertretbar, um den sachgerechten Zwischenwert zu ermitteln.   Summary In the course of the assessments on the state of noise control technology, both detailed investigations of the individual sound sources and the measurement and calculation of the existing noise contributions are necessary. If the investigation is carried out in accordance with the method described below, a final check can be made, since both the current noise situation in the vicinity of a plant is known, and knowledge is obtained as to the effort with which any additional reductions in the noise situation can be achieved. What is important here is the assessment of proportionality. If, in addition, a suitable cut-off criterion is chosen, the resulting effort can still be justified, even in case of large industrial sites, in order to determine the appropriate intermediate value.

Pm2.5 Concentration

In Japan, various countermeasures have been undertaken to reduce the atmospheric concentration of fine particulate matter (PM2.5). We evaluated the extent to which these countermeasures were effective in reducing PM2.5 concentrations by analyzing the long-term concentration trends of the major components of PM2.5 and their emissions in Nagoya City. PM2.5 concentrations decreased by 53% over the 16-year period from fiscal years 2003 to 2018 in Nagoya City. Elemental carbon (EC) was the component of PM2.5 with the greatest decrease in concentration over the 16 years, decreasing by 4.3 μg/m3, followed by SO42− (3.0 μg/m3), organic carbon (OC) (2.0 μg/m3), NH4+ (1.6 μg/m3), and NO3− (1.3 μg/m3). The decrease in EC concentration was found to be caused largely by the effect of diesel emission control. OC concentrations decreased because of the effects of volatile organic compound (VOC) emission regulations for stationary sources and reductions in VOCs emitted by vehicles and construction machinery. NO3− concentrations decreased alongside decreased contributions from vehicles, construction machinery, and stationary sources, in descending order of the magnitude of decrease. Although these findings identify some source control measures that have been effective in reducing PM2.5, they also reveal the ineffectiveness of some recent countermeasures for various components, such as those targeting OC concentrations.

Permanent magnet traction motor has the advantages of high efficiency, high power density, high torque density and quick dynamic response, which has been widely used in the traction field of electric vehicle. The high-performance control of permanent magnet traction motor depends on accurate rotor position information, which is usually obtained by using mechanical position sensors such as hall sensor, encoder and rotary transformer. However, the traditional mechanical sensor has the disadvantages of high cost, large volume and poor anti-interference ability, which limits the application of permanent magnet motor. The sensorless control technology is an effective way to solve the above-mentioned problem. Firstly, the sensorless control techniques of permanent magnet motor are classified. The sensorless control techniques of permanent magnet motor for rotor initial position, zero-low speed range, medium-high speed range and full speed range are deeply described and compared. Finally, the development trend of sensorless control technology of permanent magnet traction motor is prospected.

Lower Heating

Geopolitical issues give rise to problems in the smooth and continuous flow of oil and natural gas from the production countries to the consumers’ development countries. In addition, severe environmental issues such as greenhouse gas emissions, eventually guide the consumers to fuels more suitable to the present situation. Alternative fuels such as biogas and coal gas have recently become more attractive because of their benefits, especially for electricity generation. On the other hand, the use of relatively low heating value fuels has a significant effect to the performance parameters of gas turbines. In this paper, the impact of using four fuels with different heating value in the gas turbine performance is simulated. Based on the high efficiency and commercialization criteria, two types of engines are chosen to be simulated: two-shaft simple and single-shaft recuperated cycle gas turbines. The heating values of the four gases investigated, correspond to natural gas and to a series of three gases with gradually lower heating values than that of natural gas. The main conclusions drawn from this design point (DP) and off-design (OD) analysis is that, for a given TET, efficiency increases for both engines when gases with low heating value are used. On the contrary, when power output is kept constant, the use of gases with low heating value will result in a decrease of thermal efficiency. A number of parametric studies are carried out and the effect of operating parameters on performance is assessed. The analysis is performed with customized software, which has been developed for this purpose.
