Method of utilization and disposal of sludge from tar sands hot water extraction process and other highly contaminated and/or toxic and/or bitumen and/or oil containing sludges. |
摘要 |
<p>A method of treating bitumen and/or oil containing sludges or tailings is disclosed which comprises the steps of mixing the sludge or tailings with a secondary carbonaceous fuel, reducing the toxic substances and the moisture content of the mixture and introducing the mixture into a combustor or gasifier for combustion or gasification. 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 from harbour maintenance dredging operations, or the slurries produced as 'produced water' in in situ heavy oil production or other similar sludges. The method is particularly suitable for use in combination with a flooded mine tar sands mining method.</p> |
