Spray dryer absorption for sulphur dioxide uses

  • A.Activated carbon in a fixed bed
  • B.A lime slurry atomised into the hot gas
  • C.A limestone slurry in a wet tower
  • D.Dry powder injected into the duct

Answer: B

The heat of the gas evaporates the water so the product leaves as a dry solid collected downstream. Removal is lower than wet limestone at around eighty to ninety per cent, but there is no liquid effluent and no reheat requirement.
