    The process by which limestone (calcium carbonate) is converted to quicklime by heating then to slaked lime by hydration and naturally reverts to calcium carbonate by carbonation is called the lime cycle. The conditions and compounds present during each step of the lime cycle have a strong influence of the end product thus the complex and varied physical nature of lime products.

    Limestone forced oxidation (LSFO) is a newer process based on wet limestone scrubbing which reduces scale. In LSFO air is added to the reaction tank which oxidizes the spent slurry to gypsum. The gypsum is removed from the reaction tank prior to the slurry being recycled to the absorber. The recycle

    Wet limestone systems are well established in some sectors such as the Power Generation industry. This process is based on the large degree of contact between the circulating slurry and the flue gases. This slurry circulates in the absorber tower (or scrubber) to neutralize the condensed flue gas pollutant mostly SO2. The pH of the slurry is a key parameter to be monitored as

    The dry process is much more thermally efficient than the wet process. Firstly and most obviously this is because the meal is a dry powder and there is little or no water that has to be evaporated.

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

    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.
