Gas Supply

Liquefied natural gas (LNG) is rather competitive and can act as an alternative fuel. Zone determination for economically expedient use of this energy resource is a necessary prerequisite for solving an important task - providing consumers with gas fuel. Development of scientific bases of calculation and design of autonomous gas supply systems on the basis of liquefied natural gas is an urgent scientific and technical task that takes into account the variability of the determining factors and characteristics of the modern gas supply systems. This requires a comprehensive solution of a number of problems, the main ones are a method for the optimal functioning of the autonomous gas supply systems; development of a method for determining the optimal location of the LNG plant ; development of methods of calculation of key parameters of natural gas in the transportation scheme and the use of LNG; technical-economic substantiation of expediency of application of the developed technical solutions in the field of autonomous gas supply, remote from the gas network. The article presents the results of technical and economic studies of gas distribution systems based on liquefied natural gas, proposed a numerical algorithm and its computer implementation to determine the location of the plant for liquefying gas. Conducted calculations and comparative analysis show that LNG-based gas supply systems will provide fuel for consumers located at considerable distance from the source of gas supply (main gas pipeline or gas distribution station).

Crystalline Hydrates

The existing methods for natural gas dehydration both in fields and at compressor stations cannot always provide standatdized values of natural gas dehydration. The analysis of operation of gas distribution systems shows that dehydration units are improperly placed and are often installed out of condensation and freezing zones. This is due to the lack of consideration of phase transitions impact in gas throttling on its temperature condition. Due to insufficient natural gas dehydration, crystalline hydrates can be formed on wellbores, distribution lines and main gas pipelines and at its reduction, disturbing the operation of the equipment of compressor stations, gas distribution stations, deranging instrumentation and automation. The issues of reliability of gas pipeline systems considering the formation of crystalline hydrate plugs in pipelines have been studied. The analysis of the methods and devices preventing hydrates formation and eliminating existing crystalline hydrate plugs has shown that to provide normalized parameters of the transported gas it is necessary to perform additional water vapor, condensate drops and crystalline hydrate particles removal from natural gas at gas distribution stations during winter months. Currently applied methods used to deal with crystalline hydrate plugs in main gas pipelines require significant expenses and do not effectively ensure the reliability of pipelines operation. An energy-efficient design of an integrated treatment unit which provides an additional natural gas treatment at GDS, increases the reliability of gas pipelines protection against hydrate blockage and improves the efficiency of gas supply systems as a whole have been proposed at the Department of Heat and Gas Supply and Ventilation of the SWSU.

This article analyzes the causes of accidents on overhead gas pipelines. Special attention is paid to the operating conditions of gas distribution and gas consumption systems. The main measures aimed at reducing the environmental danger of gas supply systems operation have been identified. The main methods of increasing the reliability of gas distribution systems in the design of gas networks are considered. The complex index of reliability of gas distribution systems is used, which allows choosing the optimal version of the gas supply system.

The concept of disaster resilience has received considerable attention in recent years and it is increasingly used as an approach for understanding the dynamics of natural disaster systems. No models are available in literature to measure the performance of natural gas network, therefore, in this paper, a new performance index measuring functionality of gas distribution network have been proposed to evaluate the resilience index of the entire network. It can be used for any type of natural or manmade hazard which might lead to the disruption of the system. The gas distribution network of the municipalities of Introdacqua and Sulmona, two small towns in the center of Italy which were affected by 2009 earthquake have been used as case study. Together the pipeline network covers an area of 136 km2, with 3 M/R stations and 16 regulation groups. The software SynerGEE has been used to simulate different scenario events. The numerical results showed that, during emergency, to ensure an acceptable delivery service, it is crucial to guarantee the functionality of the medium pressure gas distribution network. Instead to improve resilience of the entire network the best retrofit strategy is to include emergency shutoff valves along the pipes.

AbstractThe successful implementation of smart metering in the European Union (hereinafter – EU) depends on criteria that are mostly determined by the Member States themselves. These criteria cover the regulatory framework and legislation necessary for the establishment and functioning of the smart metering system, the fulfilment of technical and commercial conditions, as well as the security of data collection, archiving and use. The introduction of the smart metering in different Member States has started at different times. In Latvia, its reference point was 2004, when the goal was set to maximise the use of telemetry in the natural gas metering. Currently, in the Latvian natural gas distribution system about 85 % of all consumption data are automatically processed.One of the most important components of the smart natural gas metering is natural gas commercial metering devices (hereinafter – smart meters). They differ in both the principle and type of operation. Depending on the technology used, the metering range changes, and thus the accuracy of the measurements.The article addresses some issues of further successful implementation of smart metering in the Latvian natural gas sector, as well as the measurement accuracy for smart natural gas meters.
