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.
-
Equipment Leaks
Equipment leaks, commonly referred to as fugitive emissions, are characterized as unintentional emissions. Leaks occur from equipment components such as connectors, valves, open-ended lines, pressure relief valves, and storage tank thief hatches.
-
Methanol Injection
Replacing a glycol dehydrator with methanol injection inhibits hydrate formation and eliminates dehydrator emissions.
-
Storage Tanks
Storage tanks are used to hold oil and gas condensate and operate near atmospheric pressure. Gases dissolved in the oil and condensate 'flash' out of the liquid phase. These vapors, rich in methane, may be vented to the atmosphere.
