  • Process and unit for solvent recovery from solvent diluted tailings derived from bitumen froth treatment
    Patent number: 9676684
    Abstract: A TSRU for recovering solvent from solvent diluted tailings includes a separation apparatus receiving the tailings and producing solvent and solvent recovered tailings. The separation apparatus includes a vessel, a tailings outlet, a solvent outlet, a tailings inlet for supplying a variable flow of the tailings to the vessel and a tailings recycle line connected to the tailings inlet for recycling part of the solvent recovered tailings into the variable flow of the diluted tailings to produce a flow rate controlled feed for introduction into the vessel. A tailings solvent recovery process includes separating the diluted tailings into recovered solvent and solvent recovered tailings, discharging the solvent recovered tailings, and recycling a portion of the solvent recovered tailings back into the variable flow of the diluted tailings. A method of controlling feed flow rate to a tailings solvent recovery vessel is also provided.
