A Citizen's Guide to Thermal Desorption

Thermal Desorption. What Is Thermal Desorption? Thermal desorption removes organic contaminants from soil, sludge or sediment by heating them in a . machine called a "thermal desorber" to evaporate the contaminants. Evaporation changes the contaminants into vapors (gases) and separates them from the solid material.

Treating waste by thermal desorption

Direct and indirect thermal desorption units (TDUs) (see Section 1.2 for an introduction to the types of TDU) that burn the vaporised contaminants (e.g. in the heating chamber of the TDU or in a thermal oxidiser or other associated combustion unit) rather than recovering them (e.g. through a process

Contaminated Soil Remediation through Thermal Desorption -- Synthesis

Ex-situ thermal desorption systems can also be divided into direct and indirect thermal desorption, depending on whether the heating gas directly comes into contact with the contaminated soil (thus requiring treatment). ... On average, the unit costs for ex-situ thermal desorption decreases $1.43/ton per increase of 1,000 ton of treated …
