Greenhouse gas emissions from biogas plants
The Biochemical Conversion Department is equipped with a comprehensive range of measuring instruments for the identification of diffuse methane leaks. These include an imaging method that can visualize methane losses in real time, a methane laser and various handheld devices that can be used to detect point sources of methane. In addition, there is extensive equipment available for quantifying climate-relevant emissions, both from guided and diffuse sources. Methodically, open and closed bonnets as well as large wind tunnels for piles are available and a gas chromatograph and mobile flame ionisation detectors. Additionally emissions can be determined by laser spectrometry and dispersion models using optical remote measurement methods. The area also has explosion-protected sensors and methods for the permanent monitoring of operational methane emissions from overpressure/underpressure safety devices.
