Abstract: Apparatus for reclaiming a useful oil product has an evaporation chamber, including an inlet for the waste oil, and an outlet for the vaporized oil, as a useful oil product. Burners are provided for heating the evaporation chamber to vaporize oil from the waste oil. A pump and a float arrangement are provided for monitoring the level of waste oil in the evaporation chamber, and for pumping additional waste oil into the chamber to maintain the waste oil at a desired level. Continuous operation of the apparatus results in a build up of solid wastes, e.g. heavy metals, in the chamber. After a period of operation, the burners are turned off, and the chamber opened, to enable the solid residue to be removed from the chamber. The vaporized oil can be condensed and collected.

Abstract: An apparatus and a method are provided reclaiming a useful oil product from waste oil, such as used lubricating oil. The apparatus comprises an oil feed means, a boiler, a heater and a separating means. The heater is used to heat the waste oil in the boiler to a temperature such that lighter hydrocarbons remain unvolatilized, trapping contaminants therewith. The separating means separates the volatilized lighter hydrocarbons from the unvolatilized heavier hydrocarbons and contaminants.

Abstract: The apparatus has a vaporization vessel and a combustion chamber including a burner. Contaminated water is supplied to the vessel, and vaporized. Simultaneously, any oil-based contaminants in the water are combusted or consumed, with excess air being supplied for this purpose. The water vapour and combustion products exit the chamber and may be condensed to recover the water. The recovered water contains a sufficiently low concentration of oil-based contaminants that it may be discharged.
