Alabama Power contracted Advatech to furnish the FGD systems and supervise the Stebbins absorber installation on units 1 through 4 at Plant Miller in Alabama. The
double contact flow scrubber technology is capable of achieving up to 98 percent instantaneous removal efficiency of SO2. The project included four single-tower DCFS with Jet Air Sparger technology for oxidation used to achieve 98 percent SO2 removal on Powder River Basin coal. The system uses pre-ground limestone and produces pure wallboard-quality gypsum, and the gypsum byproduct is of suitable quality to be sold for commercial use. The plant also reduces NOx and particulate matter.
