  • Patent number: 6000882
    Abstract: A system and method for remediation of contaminated soil removed from a soil site is provided. The contaminated soil is placed upon several layers of perforated heating pipes forming a remediation cell, and the entire cell is covered by a galvanized Quonset Hut-shaped steel building to prevent the escape of vapors from the soil cell. Heating air introduced into perforated heating pipes heat conductively heats the contaminated soil creating a differential pressure area around the heated pipes. This results in the migration of volatilized contaminants and moisture through the perforations in the pipe walls and into the lower pressure area within the heated steel pipes, forcing the contaminants from the soil and into an off-gas treatment system.
