TREATMENT OF BITUMINOUS SAND RESIDUES WITH LIME AT HIGH PH LEVELS |
| abstract |
Processes and systems for treating oil sands tailings streams at high pH using lime According to some embodiments, the method comprises providing a residue stream comprising from 10 to 55% solids by total weight, increasing the pH of the residue stream by combining the residue stream with lime to produce a solids stream. residue-lime mixture having a pH of at least 11.0 and dehydrating the residue-lime mixture to produce a first stream having 10% or less solids by total weight and a second stream having 50% or more of solids in total weight. The first stream may correspond to a release water stream, and the second stream may be a cake. The lime slurry may comprise about 10% lime by total weight, and may include lime hydrate, quicklime, or a combination thereof. The dewatering of the lime-residue mixture may comprise feeding the lime-residue mixture to a centrifuge unit and / or a pressurized or vacuum filtration unit. |
