Sulfur dioxide control technologies attempt to reduce SO 2 emissions through technologies utilizing conventional limestone and gypsum in flue gas desulfurization (FGD) systems. The integration of the material-handling systems for FGD projects with the existing coal-handling plant is the key to success.
A generic wet-limestone flow diagram is outlined in Figure 1. (The diagram also applies for systems using hydrated lime-Ca(OH 2)-as the reagent, where equipment and vessel sizes are smaller.)Wet ...
