A bench scale process and apparatus for determining the operating parameters, such as maximum temperature and residence time, required to remove a particular contaminant at a particular depth during a full-scale thermal desorption process, includes measuring a temperature of a representative contaminated soil sample at a particular depth as a function of residence time during a bench scale thermal desorption process. The apparatus includes a container (80) for housing the soil sample (78), at least one partition (84) positioned between adjacent layers of the soil sample (78) and at least one thermocouple (86) positioned within each layer of the soil sample (78). In determining the operating parameters, the heat flux, absorptivity, thermal diffusivity and thermal conductivity may be determined during the bench scale process and utilized to predict the operating parameters of the full scale process. <IMAGE> |
