• Analytical Methodology

As stated previously, the analytical method employed is ultraviolet absorption spectroscopy. The analytical portion of the system consists of a deuterium source lamp, a measurement (sample) cell, and a spectrophotometer with a CCD array as the ultraviolet light detector. The sample cell is a specific optical path length through which a sample of the tail gas flows. Light from the source is transmitted to the sample cell via a fibre optic cable. After passing through the gas space in the sample cell, it is transmitted to the spectrophotometer by a second fibre optic cable. The CCD array converts the light into electrical signals. These signals represent the intensity of the spectral distribution within the band of interest. The spectral data is acquired from the spectrophotometer by the system computer. The computer calculates the concentrations of the principal reactants (H2S and SO2) and from these results, the combustion air control signal - air demand.
