Abstract
An apparatus and a method for separating diluted tailings containing a hydrocarbon diluent into a recovered diluent component and a diluent recovered tailings component. The method includes introducing the diluted tailings into a diluent recovery vessel so that they form a tailings pool in the diluent recovery vessel, introducing an amount of stream directly into the tailings pool, mixing the diluted tailings which are contained in the tailings pool, and maintaining the diluted tailings in the diluent recovery vessel for a residence time. The apparatus includes a diluent recovery vessel having a tailings pool section, a steam distributor located in the tailings pool section, and a mixing device associated with the tailings pool section.
