Zusammenfassung |
Increased natural gas production in recent years has spurred intense
interest in methane (CH4) emissions associated with its production,
gathering, processing, transmission, and distribution. Gathering and
processing facilities (G&P facilities) are unique in that the wide range
of gas sources (shale, coal-bed, tight gas, conventional, etc.) results in a
wide range of gas compositions, which in turn requires an array of
technologies to prepare the gas for pipeline transmission and distribution.
We present an overview and detailed description of the measurement method
and analysis approach used during a 20-week field campaign studying CH4
emissions from the natural gas G&P facilities between October 2013 and
April 2014. Dual-tracer flux measurements and on-site observations were used
to address the magnitude and origins of CH4 emissions from these
facilities. The use of a second tracer as an internal standard revealed
plume-specific uncertainties in the measured emission rates of 20–47%,
depending upon plume classification. Combining downwind methane, ethane
(C2H6), carbon monoxide (CO), carbon dioxide (CO2), and
tracer gas measurements with on-site tracer gas release allows for
quantification of facility emissions and in some cases a more detailed
picture of source locations. |
