  • Bitumen production with solvent separation from tailings using distributor constructions and techniques
    Patent number: 10519382
    Abstract: Production of bitumen from bitumen froth can include separating the froth into a solvent diluted tailings and solvent diluted bitumen, and then the diluted tailings can be treated to recover solvent for reuse in the froth separation. The solvent recovery from tailings can employ a distributor for use in a tailings solvent recovery unit (TSRU). The distributor can include slot-shaped pressure let-down apertures and a closed curved end portion to introduce the tailings into a separation vessel. The distributor construction can have various advantages, such as facilitating manufacturing as well as effective mitigation of pre-flashing and solids segregation issues, for enhanced bitumen production and solvent recovery operations.
