Addition of organophosphonates for size control of wet calcium-based FGD byproduct solids under inhibited oxidation conditions |
摘要 |
A process for producing large, regularly-shaped crystalline calcium sulfite solids in a wet calcium-based flue gas desulfurization system is provided. A chemical crystal modifier, preferably an organophosphonate, is added to the calcium sulfite-containing solids slurry produced by the FGD process under inhibited oxidation conditions at an addition level which promotes the formation of large, regular calcium sulfite crystals that are easily dewatered.
