The method is based on establishing the calorific value of natural gas as a determinative index of its quality, taking into account all gas properties: both those that positively affect the gas calorific value and its energy content, and those that adversely affect. The generalized definition of natural gas quality as the degree to which the set of the own gas characteristics (component composition and physical properties) meet the requirements concerning energy content, safety, ecology, and other factors is given. The results of experimental researches on natural gas quality according to the developed procedure are also presented. Key words: Natural Gas; Energy Source; Natural Gas Quality; Index of Natural Gas Quality; Properties of Natural Gas; Calorific Value of Natural Gas.enArticle
