Abstract

Structures that exhibit above ambient temperatures are often found on industrial sites. These heated structures are being investigated for use as sources of infrared radiation that can be used to conduct open-path FT-IR monitoring of fugitive plumes from such sites. The use of on-site heated structures as infrared sources in open-path FT-IR monitoring promises many of the advantages of passive open-path FT-IR techniques because the arrangement is single-ended and allows spectra of fugitive plumes to be collected from a position away from the plumes themselves and possibly even outside of the plant's perimeter. The use of the heated on-site structures offers improvements in signal-to-noise ratios over passive techniques, however, similar to traditional `active' open-path techniques that incorporate a heated element (e.g., SiC) as the source of infrared radiation. Open path FT-IR monitoring has been conducted using on-site heated structures as infrared sources at an industrial site that produces agricultural chemicals to provide information about fluctuations in the concentrations of fugitive emissions produced from the site. Signal-to-noise ratios (SNR) and limits of detections (LOD) similar to those associated with traditional active FT-IR monitoring techniques are demonstrated in the spectra collected.
