  • Tar sands extraction process
    Publication number: 20020104799
    Abstract: A hot water extraction process for extracting bitumen from tar sands is taught using a conditioning agent containing sodium sesquicarbonate. The conditioning agent replaces the caustic soda agent previously used in tar sand extraction. The use of sodium sesquicarbonate substantially eliminates the production of sludge in tar sand extraction and maintains or improves bitumen recovery. The process allows for hot conditioning agent solution to be recycled to the process by use of a recycle storage tank.
