METHOD AND SYSTEM FOR RECLAIMING WASTE HYDROCARBON FROM TAILINGS USING SOLVENT SEQUENCING |
摘要 |
A method and system for extracting hydrocarbon products from waste tailings of a froth flotation unit and a paraffinic froth treatment process are provided. Bitumen and asphaltenes from the waste tailings are extracted using a serial addition of an aromatic solvent, followed by a polar-non-polar solvent. The method and system divert valuable hydrocarbons from tailings ponds. The hydrocarbon product can be used as a coating material or an emulsion fuel, for example.
