Abstract
- Carbon dioxide (CO<subscript>2</subscript>) is a known greenhouse gas and one of the largest contributors to global warming in the Earth's atmosphere. The remote detection and measurement of CO<subscript>2</subscript> from industrial emissions are not routinely carried out and are typically calculated from the fuel combusted or measured directly within ducted vents. However, these methods are not applicable for the quantification of fugitive emissions of CO<subscript>2</subscript>. This work presents the results of remote measurement of CO<subscript>2</subscript> emissions using the differential absorption lidar (DIAL) technique at a wavelength of ~2 µm. The results from the DIAL measurements compare well with simultaneous in-stack measurements, these datasets were plotted against each other and can be described by a linear regression of y (t/h) = 1.04 x − 0.02, suggesting any bias in the DIAL data is likely small. Moreover, using the definition outlined in EN 15267-3 a lower detection limit of 0.12 t/h was estimated for the 2 µm wavelength DIAL data, this is three orders of magnitude lower than the corresponding CO<subscript>2</subscript> detection limit measured by NPL in the 1.5 µm wavelength region. Thus, this paper demonstrates the feasibility of high-resolution, ground-based DIAL measurements for quantifying industrial CO<subscript>2</subscript> emissions. [ABSTRACT FROM AUTHOR]
