Thermal desorption
open-in-new
<p>Thermal desorption is an <a href="/facts/Environmental_remediation/S6wKBuhm">environmental remediation</a> technology that utilizes heat to increase the <a href="/facts/Volatility_(chemistry)/90r3ep6w">volatility</a> of contaminants such that they can be removed (separated) from the solid matrix (typically soil, sludge or filter cake). The volatilized contaminants are then either collected or thermally destroyed. A thermal desorption system therefore has two major components; the desorber itself and the offgas treatment system. Thermal desorption is not <a href="/facts/Incineration/ALwWqMlv">incineration</a>. </p>
