<p>METHOD OF UTILIZATION AND DISPOSAL OF SLUDGE FROM TAR SANDS HOT WATER EXTRACTION PROCESS A method of treating bitumen-containing sludges or tailings is disclosed which comprises the steps of mixing the sludge or tailings with a secondary carbonaceous fuel, reducing the moisture content of the mixture and introducing the mixture into a fluidized bed combustion furnace for combustion, The method may be used to process the middlings and froth treatment tailings from the tar sands hot water extraction process. The method may also be used to treat the sludges reclaimed from tar sands tailings ponds, or the slurries produced as "produced water" in in situ heavy oil production. The method is particularly suitable for use in combination with a flooded mine tar sands mining method.</p> |
