Investigation of the gas losses in transmission networks

Abstract As air pollution has become a major issue in nowadays world, reducing methane emissions from the natural gas transmission systems is an that definitely to be addressed. In order do that, there are few solutions available, such as replacement of steel pipes with high-density polyethylene (HDPE) pipes. The main causes these leaks corrosion defects and third-party interventions. paper presents new methodology for technological loss calculation system. obtain most accurate formulas, flow coefficients different cases were determined by experimental measurements. details regarding construction equipment stand, well method calculating volumes lost due this type. Thus, aerial buried studied results obtained on statistical data verified. Using study, average emission CH 4 per year Romania was calculated, it proven about 30% bigger than European average. findings study can help better understanding level losses effect final costs population, negative impact environment, case transporter does not take any measures.
