CALCULATION OF VOLUME LOSS OF NATURAL GAS DUE TO LEAKNESS OF CONNECTIONS IN THE PIPELINE |
| description |
This work considers the important problem of material losses of natural gas during its transportation and distribution. It is shown that only normative losses of gas during its transportation in Ukraine amount to about 0.9 billion cubic meters per year. Possible places of depressurization of the pipeline during gas transportation and at the gas distribution point have been determined. The results of the numerical analysis of gas volume loss due to the leakiness of the threaded connection are given on a specific example.The graphical and analytical dependence of the error of a typical flow meter on the change in gas pressure was established, and the economic component of volumetric losses due to leaky connections through which gas leakage occurs was evaluated.
Conclusions
Technological losses of natural gas during its transportation and distribution amount to approximately 0.9 billion m3 of gas per year. Material losses of gas due to leaky connections and violations of the tightness of pipelines and gas distribution points require calculations.
Formulated causes of leak tightness and possible places of gas leakage during operation of the gas distribution network.
It is noted that the gas leak has a harmful effect on the environment and a high explosion and fire hazard.
The algorithm for calculating volumetric gas losses due to the leakiness of the threaded connection is given. As a result of the analysis, the impact of gas losses on the economic component was considered, it was established that 0.422 cubic meters of gas is lost per day through one threaded connection.
It is shown how a gas leak can be detected using a gas meter. Graphical analytical dependences of pressure on gas losses are presented, from which it follows that the flow meter does not record gas leakage losses of less than 2.0 m3/day.
