VOC Control

VOC control on an oilfield site is mostly about tank and process vapors: flash gas, working and breathing losses, and dumps from separators. Those streams are hydrocarbon vapor, not a chemical-plant tail gas. Controls are VRUs, enclosed combustors, and in some cases flares.

EPA storage-vessel rules and state permits are why batteries in the Permian are no longer left to vent. The control has to actually run when the tanks are flashing. A combustor that is out or a VRU that is bypassed is not VOC control, even if the vessel is listed in a plan.

Redhead Services supplies vapor recovery units, combustors, and flare stacks used as VOC controls on production facilities. See also Quad O regulations.
