In response to changing sulfur dioxide emission regulations, electric generating companies are considering installing flue gas desulfurization technologies, and it is estimated that spray dryer absorbers (SDA) may be the preferred option for many coalfired power plants in the western United States. The increased production of SDA material is …

Impact of solid waste treatment from spray dryer absorber on the levelized cost of energy of a coal-fired power plant

The semi-dry technology has typically been employed on small to moderate size plants. Because of size limitations on the absorber tower, the maximum power served by a spray dryer is about 250–350 MW. Power plants with semi-dry FGD usually burns low-sulfur coal, in virtue of a limit of 95% on SO 2 removal efficiency. The semi-dry …
