Abstract Current methods designed to control and reduce the amount of sulfur dioxide emitted into the atmosphere from coal-fired power plants and factories rely upon the reaction between SO2 and alkaline earth compounds and are called flue gas desulfurization (FGD) processes. Of these methods, dry desulfurization processes, using fine particulate limestone, have emerged as the preferred technology for future SO2 emission control. The development of a reliable in situ spectroscopic technique for studying heterogeneous reactions, such as those occurring in FGD systems, is the key to understanding the surface mechanisms which control these reactions. The report covers the development and application of Fourier transform infrared spectrometry with photacoustic and diffuse reflectance detection for this purpose. The specific reactions chosen for study are those of SO2 with CaO, CaCO3 and Ca(OH)2. The project evaluates the feasibility of using these infrared spectroscopic techniques to monitor reactions between limestone and related materials with SO2 at various temperatures so as to aid in obtaining a clear understanding of the chemical mechanisms by which SO2 is captured.
