Abstract
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.
Claims20
A method for operating a flare, the method comprising:
- obtaining sensor data from at least one sensor of a sensing unit associated with the flare, the sensor data corresponding with at least one material received by the flare;
- obtaining environmental data corresponding with environmental conditions proximate the flare;
- modeling the sensor data and the environmental data to determine at least one measurement associated with emissions of the flare, wherein the at least one measurement is an emission cost measurement associated with the emissions of the flare, the emission cost measurement based on a carbon dioxide equivalent measurement of the emissions, the carbon dioxide equivalent measurement including carbon dioxide emissions of the flare and other emissions of the flare converted to carbon dioxide equivalents;
- determining, based on the at least one measurement, 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 associated with the at least one measurement;
- generating display data corresponding to the one or more control decisions;
- and
- operating a display device to provide the display data to a user wherein the one or more control decisions are determined by:
- obtaining, from an operator of the flare, the control objective associated with the at least one measurement;
- obtaining an objective function that quantifies a performance variable corresponding with the at least one measurement as a function of control decisions for controllable elements associated with the flare, the objective function subject to the control objective;
- and
- determining, by minimizing or maximizing the performance variable of the objective function, the one or more control decisions for the at least one controllable element of the flare, wherein the one or more control decisions are determined by minimizing the performance variable corresponding to the emission cost measurement.
