Currently in the refining industry, no on-line sensor is available to determine if a flare is achieving combustion efficiency greater than its design value of 98%. As a result, hydrocarbon air pollutants are released into the atmosphere. Researchers at The University of Texas at Austin have developed a software-based sensor that allows calculations of combustion efficiency using camera images.
The Combustion Efficiency Calculator Using Gas Flare Images software takes a color flare image from a camera and processes the pixel information to yield a prediction of the flare combustion efficiency. This technology effectively reduces pollution and is amenable to closed-loop control of a gas flare by adjusting the steam or air injection rate. The prototype has been demonstrated successfully on pilot-scale flare tests.
- Decreases pollution
- Maximizes combustion efficiency
- Uses decomposition of the RGB image data using principal component analysis and partial least squares to predict efficiency
