Assessment of Converter Station gas leak detector

Assessment of Converter Station gas leak detector

Aug 01, 2017Electronic leak testing using either air or a tracer gas has made significant advances in the last decade with the addition of new techniques, improved sensitivity and faster test cycles. The motivations for these changes are regulatory requirement (environmental, safety) and pressure on cost. Leak testing in many cases is a risk vs. probability vs. cost decision, and in many cases there is ...

  • Detection Limits of Optical Gas Imaging for Natural Gas

    While natural gas produces lower combustion carbon dioxide emissions than coal, methane, the primary constituent of natural gas, has a higher global warming potential (≈84 times CO 2 over 20 years) leading to an interest in reducing CH 4 emissions, and therefore in natural gas leak detection methods. This study presents recent tests of the detection efficacy of one of the most popular leak detection technologies used in mid- and upstream sectors of the natural gas industry: optical gasAuthor: Daniel Zimmerle, Timothy Vaughn, Clay S.

    reported. The QEPAS sensor was integrated into a vacuum-seal test station for mechanical valves. Sulfur hexafluoride (SF6) was selected as the leak tracer gas and a 1% SF6 in N2 mixture was employed. SF6 is an extremely stable gas with unique physical and chemical properties that make it an ideal candidate for leak detection applications [16
