The gas scrubber consists of a packed column, spray header, mist eliminator and a re-circulation tank.

 The scrubbing system in general comprises of packed bed scrubber, blower, pump, piping, ducting etc. The gas enters the bottom of the scrubber and water / caustic is sprayed from the top. As the gas travels upwards it comes in contact with scrubbing liquor in the packed section where the gas gets absorbed in the liquor. A mist eliminator is placed above the packing to remove the entrained water droplets. The cleaned gas is finally discharged into the atmosphere through a stack.
