The only slaked lime scrubber for a cement plant was built in the UV plant. There, the kiln exhaust gas flows through a Venturi reactor with an expanded fluidized bed formed by the absorbent which consists of a blend of hydrated lime (slaked lime) and raw meal [9]. A more detailed description of the UV reactor is attached (see chapter 7).

Energy Efficiency and Saving in the Cement Industry

In the cement industry pyroprocessing (processing the raw material into cement under a high temperature, e.g., above 800 0 C) is a very common technological procedure, which accounts for 74% of the energy consumption in global cement/concrete industries. Since the thermal efficiency through the use of this conventional technology of pyroprocessing is slightly higher than 30% on average
