Abstract
Flare control with vent gas recovery is disclosed. Vent gas is recovered for end use (e.g., process gas, fuel gas, etc.) while a flare is in a standby state. Upon detection of a flare event that causes vent gas to flow to the flare, the flare is changed from the standby state to an active state. The flare is controlled for efficient combustion of vent gas that flows to the flare during the flare event. Upon detection of a subsidence of the flare event, the flare is changed from the active state to the standby state. The flare can remain in standby until another flare event is detected. The flare event is detected when one or more of the disclosed flare activation conditions are detected, and subsidence of the flare event is detected when the flare deactivation conditions are detected.
