'Dry' flue-gas desulphurisation possible on combustion

The fine powder's reactivity enables it to react more effectively with pollutants than conventional small surface area lime or crushed limestone, capturing up to 99% of sulphurous gas pollutants. The dry FGD system does not require water to capture sulphurous gas emissions. The reaction forms gypsum (CaSO 4 2H 2 O). The flue gases then pass through a conventional filtration process to remove particles

PARTICLE SIZE DISTRIBUTION AND SPECIFIC SURFACE

For the determination of the specific surface area (SSA), the Blaine method (BM) has been commonly used for cement . BM is a rather empirical method particularly designed for cements, and therefore its application for SCMs requires some adaptations. For example, a different plunger has been proposed by to avoid removing it.
