Abstract
An apparatus and methods for removing contaminants from substances are provided. The apparatus includes a treatment vessel, a pump, and a means to suspend a contaminated substance within a flow of a low surface tension solvent. Circuitous piping is provided to cycle the flow of the solvent through the treatment vessel. The methods include exposing a contaminated substance to a flow of low surface tension solvent that removes the contaminant from the substance and transports it away from the substance. In further examples, the pressure and temperature within the processing system can be increased to put the solvent into a supercritical phase.
