    2017-10-15  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 SO2 removal efficiency.
