摘要： A data stream indicative of a first set of flare tip parameters is received. A second set of parameters is determined based on the first set of flare tip parameters. A control signal is sent to an actuable device based on the first set of parameters and the second set of parameters. The actuable device is configured to maintain at least one parameter of the first set of parameter and the second set of parameters within a specified range.

摘要： Systems and methods for monitoring emissions of a combusted gas are provided. The method includes determining a first net heating value of a flare gas. The method also includes determining a second net heating value of a combustion gas including the flare gas. The second net heating value can be determined based upon the first net heating value and a volumetric flow rate of the flare gas. Based upon the value of the second net heating value, an empirical model or a non-parametric machine learning model can be selected. A combustion efficiency of the combustion gas can be determined using the selected model, the second net heating value, and selected ones of the process conditions and the environmental conditions. Total emissions of the combustion mixture can be further determined from the combustion efficiency and a volumetric flow rate of the combustion gas.

摘要： 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.
