Abstract

This work continues with the development of a non-dispersive UV optical sensor for stack emissions for SO₂ and NO₂. These gases are among the most important ones in the emissions of the petrochemical industry. The NDUV consists of three optical channels sensing different spectral regions: 300 nm for SO₂, 380 nm for NO₂ and 320 nm used as a common reference. Each channel has an interference filter centered at each channel's wavelength, and a photodiode with control electronics. Calibration curves and the effect of cross interference on concentration measurements of these gases are shown.
