Semi-Dry FGD Alkaline (Caustic Soda; Magnesium Hydroxide) WFGD

Note: 1. Combination of SO3 Sorbents can be employed.2. Multiple Sorbents can provide multi pollutant mitigation

(SO3; Hg; HCL; Dioxin; etc.)

• Na2CO3 + SO2 + 1/2O2 → Na2SO4 + CO2

• Na2CO3 + SO3 → Na2SO4 + CO2

• Na2CO3 + 2HCl → 2NaCl + H2O + CO2

• Na2CO3 + 2HF → 2NaF + H2O + CO2

• Na2CO3 + NOx → NaNO3 + CO2

Na2SO4, NaCl, NaF and NaNO3 are collected in fly ash.

SODIUM SORBENT REACTIONS

CALCIUM SORBENT REACTIONS

26

• Ca(OH)2 + SO2 → CaSO3 + H2O

• Ca(OH)2 + SO3 → CaSO4 + H2O

• Ca(OH)2 + 2HCL→ CaCl2 + 2H2O

• Ca(OH)2 + 2HF → CaF2 + 2H2O

CaSO3, CaSO4 , CaCl2 and CaF2 are collected in fly ash.
