A method for operating a flare includes obtaining sensor data associated with emissions of the flare from sensors of a sensing unit associated with the flare. The method also includes determining, based on the sensor data, one or more control decisions for at least one controllable element associated with the flare to achieve a control objective for the flare. The control objective is associated with the emissions of the flare. The method also includes generating display data corresponding to the one or more control decisions. The method also includes operating a display device to provide the display data to a user.

A system for flare combustion control includes a sound speed measurement device for measuring sound speed in a flare vent gas, and a flare combustion controller including a memory and a processor. The processor is configured to receive the measured sound speed and determine, based on the measured sound speed, a molecular weight of the flare vent gas. The processor is further configured to determine, based on the determined molecular weight, a net heating value of the flare vent gas, and adjust the net heating value of the flare vent gas by regulating an amount of a supplemental fuel gas in the flare vent gas.

The invention relates to a computing device and method for estimating (100) a combustion efficiency value during flaring, over a time period, said method comprising the following steps: Acquiring (140) a video stream of the flare flame (61) over the time period; Segmenting (150) the video stream in several video segments, each video segments being associated with a video segment duration; Analyzing (160) the video segments, using a correlation model, so as to classify each video segments in at least one flame state category; andComputing (170) the combustion efficiency value, said computing (170) step using the video segment durations and a plurality of unburned reduction index values, each of said unburned reduction index values being specific to one of the flame state categories, specific to the industrial plant and calculated using computational fluid dynamics.
