Abstract: The current research status and progress of thermal desorption offgas treatment technologies were reviewed. Four treatment technologies including condensation, adsorption, thermal combustion and catalytic combustion are used in engineering. Condensation is mainly used as a pretreatment of high concentration of organic pollutants in exhaust gas due to its low removal rate. Adsorption and thermal combustion have high removal rate of pollutants in the exhaust gas but with high cost. Catalytic combustion is generally used for purification of low concentration pollutants in exhaust gas. For developing thermal desorption equipment in line with the socioeconomic level of China, two new thermal desorption gas processing technologies including cement kiln co-processing technology and non-thermal plasma technology are proposed. The cement kiln co-processing technology is based on the principle of thermal combustion and can be used for treating thermal desorption offgas of contaminated sites around the cement plants. Non-thermal plasma technology has promising prospects with the advantages of high efficiency, low cost and no secondary pollution.
