【 摘 要 】

Scope of Study: Current development trends for all gas infrastructure systems utilizing natural gas and alternative fuels (most commonly, liquefied hydrocarbon gas) do not provide due justification for all criteria influencing the efficiency of such systems. Meanwhile, expediency of natural or liquefied gas supply shall be calculated by taking into account network configuration for settlements, their population density, type of gas equipment utilized by customers and other relevant factors. Very often, dismissal of such criteria leads to tremendous and unjustified investment into gas distribution systems, thus decreasing their economic viability and efficiency. The purpose of this study is development of an optimal structure for natural and liquefied hydrocarbon gas distribution system that taken into account individual characteristics of gas fuel consumption by metropolitan community. Materials and Methods: The study is based on generalization and systematization of gasification data provided by gas distribution companies operating in Russian Federation. System analysis and mathematical simulation have been used to find optimal values for relevant limitations. Results: Optimal operation parameters of gas distribution system utilizing natural and liquefied hydrocarbon gas and taking into account gas consumption rates have been found. System analysis of elements of distribution system under construction allowed estimating the number and specific features of gas fuel consumption in various settlements, number of said settlements and their annual gas consumption rates and number of distribution stations in terms of regional supply of natural and liquefied hydrocarbon gas. Conclusions: We have evaluated gas distribution systems parameters based on annual gas consumption rates. The scope of application for natural and liquefied hydrocarbon gas within specified gasified region has been established. We have also provided recommendations on practical application of obtained research data.
