Methane emission into the atmosphere through vent pipe is a common technological operation in the gas industry. Methane emission sources are unique, non-stationary in time, high-speed and low-temperature. The main difficulties of developing mathematical models related to the dispersion of pollutants in the atmosphere are large volumes of initial data, including variable climatic characteristics and terrain parameters. The authors of the article consider the problems of setting up and conducting studies at real objects with a long period of natural gas emission as well as the selection of appropriate equipment. The schemes of measuring devices placement and the dependence of the maximum methane concentration on the distance from the emission source are given. The obtained results can be further used as input information for mathematical models of natural gas dispersion in the atmosphere. The article is a continuation of the authors' work devoted to the problem of developing mathematical models for the dispersion of emissions from salvo sources.
