A method for recovery of hydrocarbon diluent from tailings produced in a bitumen froth treatment plant comprises introducing the tailings into a steam stripping vessel maintained at near atmospheric pressure, said vessel having a plurality of interior, vertically spaced shed decks, and distributing the tailings over said shed decks. Steam is introduced below the shed decks for vaporizing the major portion of the contained diluent and some water.

A process for recovery of hydrocarbon diluent from tailings produced in a bitumen froth treatment plant comprises introducing the tailings into a vacuum flash vessel maintained at a sufficiently low sub-atmospheric pressure to vaporize the major portion of the contained diluent and some water. The residual then pool near the bottom of the flash vessel. Steam is then introduced into the tailings pool for vaporizing residual diluent and some water.
