Thermal desorption treatability studies on selected mercury-, PCB-, and organic-contaminated waste streams
- Oak Ridge Y-12 Plant, TN (United States)
Thermal desorption is a process that has been targeted to remediate selected Department of Energy hazardous/mixed waste soils and sludges by removing mercury, polychlorinated biphynyls (PCBs), and volatile organic contaminants to the satisfaction of the Land Disposal Restrictions (LDR) and the Federal Facilities Compliance Act (FFCA). It is a batch process in which waste solids are heated at a given temperature for a specified period of time to volatilize the contaminants, which are then separated from the radioactive components and subsequently collected for either immediate disposal or further treatment. This volatilization process is dependent on variables such as the solids temperature, residence time, and carrier gas flow. This paper discusses the effect of these parameters on the contaminant removal during thermal desorption. The experimental program will demonstrate that thermal desorption is the method of choice for the removal of these contaminants and provide data for pilot-scale demonstrations.
