This white paper provides an analysis that presents the sensitivity of compressor EFs to different strata of Subpart W measured leak rates by presenting compressor EFs that exclude data above several leak thresholds. The analysis provides updated EFs that reflect the related emission reduction if only leak rates above the various thresholds are excluded, which is indicative of the reductions that can be achieved by focusing on repair of a subset of larger leaks rather than all leaks detected. Based on a large dataset of Subpart W measurement data compiled by PRCI, analysis shows that...
This white paper provides an analysis that presents the sensitivity of compressor EFs to different strata of Subpart W measured leak rates by presenting compressor EFs that exclude data above several leak thresholds. The analysis provides updated EFs that reflect the related emission reduction if only leak rates above the various thresholds are excluded, which is indicative of the reductions that can be achieved by focusing on repair of a subset of larger leaks rather than all leaks detected. Based on a large dataset of Subpart W measurement data compiled by PRCI, analysis shows that a methane reduction of over 95% can be achieved by mitigating about half of the compressor leaks and over 70% of compressor leak emissions can be eliminated by focusing on less than 15% of leaks.
