Thermal desorption technologies consist of a wide variety of processes that vaporize volatile and semi-volatile organics from soil at temperatures of 90 degrees-550 degrees C and residence times of 20-60 min. Ex-situ thermal desorption has been applied at different sites with successful results, appearing cost-effective, especially in comparison to incineration.

Abstract
Thermal desorption technologies consist of a wide variety of processes that vaporize volatile and semi-volatile organics from soil at temperatures of 90 degrees-550 degrees C and residence times of 20-60 min. Ex-situ thermal desorption has been applied at different sites with successful results, appearing cost-effective, especially in comparison to incineration. The paper offers a detailed analysis of the different thermal desorption processes, with particular regard to the following aspects: treatment requirements (pretreatment, soil handling requirements, off-gases treatments), costs, full scale experiences.File in questo prodotto:
