Abstract (en)
[origin: WO2007031552A1] A method of removing SO<SUB>3</SUB> from a flue gas stream having increased amounts of SO<SUB>3</SUB> formed by a NOx removal system, includes injecting a sorbent composition into the flue gas stream. The sorbent composition includes an additive and a sodium sorbent such as mechanically refined trona or sodium bicarbonate. The additive is selected magnesium carbonate, calcium carbonate, magnesium hydroxide, calcium hydroxide, and mixtures thereof. The concentration of the SO<SUB>3</SUB> in the flue gas stream is reduced and the formation of a liquid phase NaHSO<SUB>4</SUB> reaction product is minimized.
