Zusammenfassung:	An in situ thermal desorption system may be used to remove contamination from soil. Off-gas removed from the soil may be transported from the soil to a treatment facility by high temperature hoses and plastic piping. The use of high temperature hose and plastic pipe may reduce the capital cost, installation cost, and operating cost as compared to conventional transport systems from thermal desorption soil remediation systems. The high temperature hose and plastic pipe are highly resistant to corrosion caused by the off-gas. The treatment facility may separate the off-gas into a liquid stream and a vapor stream. The liquid stream and the vapor stream may be processed to reduce contaminants within the liquid stream and vapor stream to acceptable levels.
