Sources of Air Emissions
Leaks and routine venting during the extraction,
processing, and transportation of NG result in
emissions of GHGs and, depending on the local
composition of unprocessed gas, other pollutants
that contribute to locally- and regionally-elevated
air pollution that may threaten public health. There
are numerous individual components used throughout
NG and oil production systems that are prone
to leaks, including compressors, valves, pumps,
flanges, gauges, and pipe connectors.
