The Ionada Semi-Dry Scrubber utilizes a proprietary blend of nano porous chemical semi dry absorbents consisting primarily of sodium bicarbonate and zeolite catalysts. These nano porous materials are highly effective at reacting with the sulfur oxides to form heat stable benign salts.
2NaHCO3 + SO2 + 1/2O2 → Na2SO4 + 2CO2 + H2O
AlNaO6Si2 as a catalyst and absorbent, where X & Y denote the reactants and the C the catalyst.
X + C → XCY + XC → XYCXYC → CZCZ → C + Z
