TREATMENT OF PRODUCED WATER CONCENTRATE |
摘要 |
Water, for example produced water from a steam assisted gravity drainage (SAGD) or cyclic steam stimulation (CSS) heavy oil recovery operation, is treated, for example to recover water re-use in creating steam. The produced water is concentrated, for example in one or more thermal treatment devices such as an evaporator and a crystallizer. A solvent and a compound or solution comprising multivalent cations is added to the concentrate. Solids precipitate and are separated from the concentrate. The solvent may be recovered for re-use in treating more concentrate. |
