Spray Dryer Absorber (SDA) Technology: Flue Gas

Spray dryer absorber (SDA) technology is observed to remove as much as 95% SO 2 from high sulfur coals, which is a characteristic reduction outcome for western low sulfur coals. It is a requirement that the SDA be upstream of a particulate control device so that the sorbent can be removed from the flue gas.
