摘要
An in-situ thermal desorption system and process is utilized for mobilization and removal of nonvolatile and semi-volatile hydrocarbons from contaminated soil in the vadose zone. Persistent hydrocarbons are thermally desorbed by direct heating of the contaminated zone through combustion of fuel and air in a burner underneath the contaminated soil zone. The generated soil vapors are collected and treated by soil vapor extraction techniques.
