coal-fired boiler mixes with limestone slurry. Flue gas from the ESP enters the absorber at the bottom, while limestone slurry enters the absorber from the top, and both move in the counter-flow direction. In this process, SO 2 is removed from flue gas in the form of gypsum, a byproduct (see Figure 5: Overview of wet limestone-based FGD process).
