摘要：
A method for recovering hydrocarbon diluent present in froth treatment tailings, comprising introducing the tailings into a vessel; adding a first portion of steam into the vessel to form a vapour-tailings interface; and operating the vessel to increase the exposure of the tailings to the vapour-tailings interface formed in the vessel.
