ABSTRACT:
A process for removing and recovering specific constituents from a waste stream at higher temperatures than the boiling point of the specific waste within a compound of chemicals and inert materials forming ninety-five (95%) percent of the waste stream in the United States. 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 vaporized 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 otherwise be mixed with the waste, or an emulsion with the waste stream, containing a heavy metal such as cadmium, arsenic, lead, or some other type of heavy metal which may be a threat to the environment.
