Abstract:
A method for thermal desorption of contaminates in soil comprising:a. excavating the contaminated soil; b. placing the contaminated soil in a thermally conductive treatment vessel containing a gas exit pathway; c. transporting the treatment vessel to an insulated treatment chamber: d. installing the treatment vessel in the treatment chamber; e. inducing flow of air through an air dryer; f. inducing flow of the dried air through an air heater; g. heating the dried air; h. inducing flow of the dried and heated air into the treatment chamber to contact the treatment vessel and flow through the contaminated soil to the gas exit pathway; i. exhausting heated air and contaminates from the gas exit pathway; j. stopping flow of the dried and heated air when the soil is decontaminated; k. removing the treatment vessel from the treatment chamber; l. transporting the treatment vessel to the soil disposition site; and m. transferring the soil from the treatment vessel to the disposition site.
