Abstract:

A field demonstration project was conducted at Letterkenny Army Depot in the fall of 1985. This pilot testing project demonstrated that the low temperature thermal striping process could successfully remove volatile organic compounds VOCs from soils. Soils were treated in a thermal processor, an indirect heat exchanger used to heat and dry the contaminated soil. The net effect of heating the soil was to evaporate volatile contaminants. A carrier gas i.e., air was introduced to the unit to enhance contaminant removal. Contaminatns in the off-gases were thermally destroyed in an afterburner. This report presents the results of a comprehensive study that evaluates the economics of four separate low temperature thermal stripping LTTS system sizes and two separate system configurations i.e., with and without flue gas scrubbing for application at three separate size sites. LTTS system capital and operating costs are presented in total dollars and unit cost.
