Vapor Recovery Units
Vapor recovery units (VRUs) are commonly used to capture methane emissions from storage tanks and a variety of other low pressure sources such as pipeline pigging operations, compressors, and dehydrators.
-
Engine Exhaust
Natural gas-fired engines and turbines are used to run compressors throughout the natural gas value chain. In many operations, the natural gas stream is used to power these engines and turbines. Methane emissions result from incomplete combustion.
-
Glycol Dehydrators
Glycol dehydrators are used to remove water from gas. The glycol absorbs water and methane when contacted with the wet gas. Glycol is then regenerated, where absorbed methane is vented to the atmosphere along with the water vapor.
