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.
Key benefits of fixed bed with CleanCalco®
- Low investment cost, low footprint and low maintenance
- Dry by-product & no liquid treatment requirement
