Dow UAS NOx Stack Boiler Emissions B. Gullett

Short summary
Aerial emission sampling of four natural gas boiler stack plumes was conducted using an unmanned aerial system (UAS) equipped with a lightweight sensor–sampling system for nitrogen oxide pollutant measurements. The results were compared to simultaneous measurements from the stacks using conventional gas extraction methods. The emission values between the two methods varied by less than 6 %, demonstrating the accuracy of UAS-based pollutant measurements against a known source concentration.
