Measurement of low mercury concentration in waste gas of industrial processes for determination of performance characteristics of the standard reference method EN 13211 (2001) and the alternative method CEN/TS 17286 (2019) (Sorbent Trap Monitoring) (FKZ 3721 52 204 0)
The aim of the project commissioned by the Federal Environment Agency is to compare mercury measurement methods for air-side emissions from e.g., power plants, cement plants, and waste incineration plants. The state-of-the-art standard wet chemical reference method according to EN 13211 will be compared with the sorption on activated carbon ("sorbent traps") according to CEN TS 17286, which is widely used, especially in the USA. The aim is to test the suitability of the methods for half-hourly short-term measurements, in particular for low mercury emission concentrations below 5 µg/Nm3, and for the calibration of continuous measuring instruments. The contractor is VDZ Service GmbH, which, together with the measurement institutes ANECO and TÜV Rheinland, carries out parallel measurements to validate the methods at four industrial plants. Ökopol is supporting the project by conducting literature research. Based on the findings, process variables for the standard reference procedure according to EN 13211 and CEN TS 17286 are to be determined.
