Measurements of methane leaks from biogas plant based on infrared camera

International audienceMinimization of methane leakages in biogas plants is a challenge to ensure the environmental benefit of anaerobic digestion systems. Current estimation methods highlight uncertainties mainly due to spatial and temporal variations of leakages. Therefore, a real-time detection and quantification technology would be the achievement of a great bet to limit such uncertainties. The presented novel method approaches this optimum. The technique is based on a turbulent gas flow estimator model adapted to infrared image sequences. After a lab calibration phase, on-site experiments were conducted to validate the new method and compare its results with traditional measurements techniques
