Emplacement of Wastes in Salt Caverns

• Salt caverns are initially filled with brine.



• Wastes are injected as a slurry of waste and water or brine.



• The incoming waste displaces the brine which is brought to the surface and either sold or injected into a disposal well.



• Caverns act like giant oil/water/solids separators.
  • solids sink to the bottom and oil and other hydrocarbons float to the top of the cavern.
