An apparatus is described for recovering clean water and substantially dry, fluidizing oil-free solids from aqueous solids dehydrated in a light fluidizing oil medium, comprising: a tank to receive a stream of the aqueous solids having a mixing mechanism, a light fluidizing oil reservoir, means for transmitting light fluidizing oil from the light oil reservoir to the tank, an evaporator, a conduit extending from the tank to the evaporator, a first condenser, a conduit extending from the evaporator to the first condenser, an oil-water separating means, a conduit extending from the first condenser to the oil-water separating means, means for separately withdrawing light oil and clean water from the oil-water separating means. A conduit extends from the withdrawing means to the light fluidizing oil reservoir. A liquid-solid separating means is included. A conduit extends from the evaporator to the liquid-solid separating means, a deoiler means, a conduit extending from the liquid-solid separating means to the deoiler means. A conduit extends from the liquid-solid separating means to the light fluidizing oil reservoir, a boiler-furnace having a boiler region and a heating region, a conduit extending from the boiler region of the boiler-furnace to the evaporator, a conduit extends from the heating regoin of the boiler-furnace to the deoiler means, a second condenser, a conduit extending from the deoiler means to the second condenser, and means connecting the second condenser with the light fluidizing oil reservoir.
