| Popis: | The relevance of research. Natural gas is currently the uncontested hydrocarbon resource used primarily as a fuel. The main component of natural gas is methane, its content in gas exceeds 95 %. When natural gas is transported through pipelines, fugitive emissions inevitably appear through detachable connections. Methane is a greenhouse gas and leads to climate warming. The Paris Agreement, ratified by Russia, provides for the reduction of greenhouse gas emissions to reduce the burden on the environment. The results discussed in the article are relevant, since these recommendations will improve the efficiency of control over fugitive emissions of methane into the environment. The purpose of the research was to develop a method for determining the volume of natural gas leaks into the atmosphere through detachable leaky joints on gas pipelines using a laser methane detector that records the amount of leakage. The method involves the development of analytical models for converting the linear methane concentration in the area of the leak into volumetric values. Objects: an experimental setup designed to simulate natural gas leaks into the atmosphere. The stand allows simulating leaks of varying intensity using special replaceable plugs with holes of different diameters. Methods. To substantiate the proposed provisions, the methods of least squares, asymptotic coordinates, and order statistics were used. Results. A technique for quantitative determination of methane emissions through detachable connections of a gas transmission system is presented. To develop the methodology, a laboratory stand was specially designed and manufactured, with the help of which empirical data were obtained for analytical models for converting the linear concentration of methane in the leakage area into volume concentration. |
