Flue gas desulfurization

Dry, semi-dry and wet methods are commonly used for desulfurization of flue gas from coal-fired power plants. The traditional dry desulfurization methods are oxidation method and solid phase adsorption method, and the effect is obvious in the case of low sulfur content in flue gas.

Hydrated lime is normally used as SO 2 sorbent in spray dry scrubbers, whereas limestone is considered unreactive under conditions prevailing in such a system. However, limestone is more easily available and several times cheaper than hydrated lime. We tried to use limestone to remove SO 2 from flue gas in the semidry FGD process with a powder-particle spouted bed.
