  • Scrubber - Wikipedia

    Scrubber systems (e.g. chemical scrubbers, gas scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams. The first air scrubber was designed to remove carbon dioxide from the air of an early submarine, the Ictineo I, a role for which they continue to be used today.

  • 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.

  • Spray Dry Scrubber - an overview ScienceDirect Topics
