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.
