In Fixed Bed FGC technologies, the flue gases flow through a bed of reagent, usually calcium carbonate granules (CaCO3), granulated hydrated lime or a mix of the two. The neutralization of acid gases occurs in the beds and is focused especially on HF and SO3 with a slight effect on HCl.
Carmeuse offers dedicated granules of calcium carbonate that are adapted to these applications in terms of reactivity and particle size distribution.
