Emission monitoring using Differential Absorption Lidar (DIAL)
Stack Emissions Monitoring
Information
The DIAL system is able to monitor atmospheric pollutants remotely, at ranges of up to 1 km. DIAL measurements are real-time, directly traceable to primary standards of gas concentration and are free from interference and contamination. The DIAL technique can be used for a number of atmospheric monitoring campaigns, including:
1. Remote measurements into inaccessible, hazardous or elevated areas
2. Wide area surveys of diffuse sources, including methane from landfill sites
3. Measurement of total industrial site emissions, including flares and tanks
4. Boundary fence monitoring
5. Identification and quantification of leaks and fugitive emissions
6. Plume tracking and source identification from complex industrial plant
7. Environmental impact assessment
