Use of limestone for SO2 removal from flue gas in the ...

2000-10-15  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.
