Route Blowdown Gas to Low Pressure System
Rerouting blowdown gas (from stations, equipment, or pipelines) to an existing low-pressure gas system can reduce the amount of high-pressure natural gas that would otherwise be emitted to the atmosphere.
-
Reroute Glycol Skimmer Gas
Some glycol dehydrators use condensate separators to recover natural gas liquids and the non-condensable gas (or skimmer gas) is often vented to the atmosphere. Rerouting the skimmer gas to the reboiler firetubes can reduce emissions.
-
Pipeline Blowdowns
Pipeline blowdowns are routine operations on transmission and distribution systems to allow operators to safely perform maintenance. This practice involves isolating and depressurizing a section of the pipeline and venting the gas to the atmosphere.

Pneumatic Controllers
Natural gas-powered pneumatic controllers are used in the natural gas industry to operate valves that control liquid level, pressure, and other processes. Some controllers are designed to bleed continuously, while others may bleed gas only when actuated.
-
Liquids Unloading
Accumulation of liquids (i.e., water and hydrocarbons) in a mature gas well can slow down gas production. To increase gas production, the liquids must be cleared from the well. Removing the liquids is commonly referred to as “liquids unloading.”
