ABSTRACT:
A process for removing and recovering specific constituents from a waste stream at higher temperatures than the boiling point of the specific constituents. In the process, the waste is moved at a specified retention time, through a heat zone, thus increasing the temperature of the waste stream. There is further provided a means to separate certain components in that waste stream whereby the components are evaporated and are released in a gaseous state, either from a liquid or a solid within the waste stream. The gaseous components are then transferred in the gaseous state through a flow of an inert medium, such as nitrogen gas, to inhibit combustion of the components, or to prevent the combination of oxidation, or oxygen being used as a catalyst to form even more hazardous compounds. The gaseous components then are released in a distilled state, which would then be mixed with the waste, or an emulsion with the waste stream, containing heavy metal such as cadmium, arsenic, lead, or some other type of heavy metal which may be a threat to the environment.
