Thermal Desorption/Ultraviolet Photolysis Process Technology Research, Test, and Evaluation Performed at the Naval Construction Battalion Center, Gulfport, Mississippi, for the USAF Installation Restoration Program. Volume 2
Abstract
The objective of this effort was to examine the feasibility of using a thermal desorption/ultraviolet (TD/UV) destruction technology to treat Herbicide Orange (HO) -contaminated soil at the Naval Construction Battalion Center (NCBC), Gulfport, Mississippi. The IT Corporation pilot -scale TD/UV apparatus was used to successfully treat 1700 pounds of sandy loam, cement stabilized, soil that had been contaminated with HO and 2,3,7,8 tetrachlorobenzo-p-dioxin (TCDD). The TD/UV process volatilizes organic compounds from the soil matrix; collects the desorbed organics in a solvent; and, destroys the contaminants with high-intensity ultraviolet light. The desorption process occurs between 850 to 1150 degrees F. in a nitrogen atmosphere to prevent combustion of the organics. Analysis of feedstock showed TCDD levels ranged from 233-272 parts per billion (ppb). Concentration in the treated soil, measured as the sum of all dioxin/furan congeners, was less than 1ppb, the USAF criterion.
