Abstract
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.
