Current status and development prospects of the gas distribution system in the Angarsk urban district

The aim of the research is to analyse the status of the low-pressure gas distribution system functioning in of the Angarsk urban district (AUD), as well as to identify possible directions for its reconstruction and modernization. These measures are aimed at developing the housing stock and the capacity of industrial enterprises. The number of local and distributed consumers in Angarsk and the Angarsk urban district was used to analyse the current load of mediumand low-pressure gas supply systems. To check the status of the gas supply system in the region, a theoretical study was undertaken involving analysis, abstraction, and induction. Choosing the methods for reconstruction and modernization of the system required abstraction from the current gas type used in the AUD. Particular attention was drawn to the forecast of gas consumption in the next 10–20 years and possible gasification of the Irkutsk region due to the launch of the main gas pipeline "Power of Siberia". The conducted analysis of the current status of the gas distribution system revealed shortcomings, indicating the need for reconstruction and modernization of network sections, as well as control and regulation units. In addition, the reliability of the operating equipment was checked, considering its service life. The data obtained were used to develop guidelines for reconstructing the existing gas distribution systems and modernizing control units and gas equipment both technically and economically. An increasing volume of gas consumption by the housing stock and the industrial sector compels us to seriously consider the reconstruction of the gas supply system. However, it is essential to develop a gas supply system that accounts for the possibility of transition to natural gas. This factor calls for the project solutions to be compatible with any type of gas fuel.
