Thermal Desorption is a term applied to many different types of soil remediation technologies. All of these technologies consist fundamentally of a two-step process, as illustrated as the right picture shows.

In Step 1, heat is applied to a contaminated material, such as soil, sediment, sludge, or filter cake,to vaporize the contaminants into a gas stream that.

In Step 2, is treated to meet regulatory requirements prior to discharge.

A variety of gas treatment technologies are used to collect, condense, or destroy these volatized gases. WPE THERMAL DESOPRTION UNIT obtains a high efficiency remediation performance which can reduce the residual oily content by 0.1%-0.3%.

APPLICABILITY OF THERMAL DESORPTION SYSTEMS

In general, thermal desorption is capable of treating various materials, including soil,sediment, sludge, and filter cake, contaminated with a wide range of organic contaminants.Petroleum, volatile organic compounds (VOCs), semivolatile organic compounds (SVOCs), pesticides, and other compounds with boiling points up to about 600°F are typically processed through direct – or indirect-contact thermal desorption units. Contaminants with boiling points above 600°F, such as polychlorinated biphenyls (PCBs), dioxins, and furans, may be treatable with higher-temperature systems. Thermal desorption is not thought to be effective for the treatment of organic corrosives and reactive oxidizers and reducers.

More specific guidance on the effectiveness of thermal desorption for various specific contaminants is presented in Table 1.
