Flue Gas Desulfurization

Summary

TOYO offers flue gas desulfurization process technology using a Magnesium Hydroxide Process that removes, at high efficiency, the SO₂ contenting in the flue gases from boilers and furnaces, and a Wet-Electrostatic Precipitator technology that prevents bluish smoke.

Magnesium Hydroxide Desulfurization

This is a flue gas desulfurization technology that uses magnesium hydroxide as an absorbent, and has the following three features:

This technology is specifically suited for a plant in the coastal area The absorbent i.e. magnesium sulfate solution after desulfurization process of dust removal and oxidation can be discharged into the sea because its components are the same as seawater.

Wet-Electrostatic Precipitator

The Wet-Electrostatic Precipitator eliminates bluish smoke coming out from high sulfur fuel. When the high sulfur fuel is combusted, high-concentration SO₂ gas develops proportionally along with sulfuric acid mist which causes bluish smoke. The sulfuric acid mist cannot be removed with ordinary desulfurization process. By treating the desulfurized flue gas with the Wet-Electrostatic Precipitator, 90 to 99% of the sulfuric acid mist can be collected and removed efficiently.
