Abstract:

Several of the U.S. Armys Manufacturing facilities use activated carbon columns to remove 2,4,6-trinitrotoluene TNT and cyclotrimethylene- nitramine RDX from the plant wastewater effluents. The eight principal generators of explosive-laden waste carbons from those columns utilize about 466,000 1byear of such carbons, according to questionnaires completed by them. Disposal of the spent i.e., explosive-saturated carbon from these installations has classically been accomplished by open burning, but this is no longer allowed in many areas. This report investigates three other alternatives Thermal Reactivation for Reuse, Oxidative Incineration and Ash Burial, and Thermal deactivation and Carbon Burial. Explosive-laden spent carbons from four Army Ammunition Plants AAPs have already been processed by a commercial reactivator. Thermal reactivation for reuse was accomplished with about 90 yield weight basis, but the product was sometimes structurally weak and thus liable to crumble, forming undesirable fines. The only experience with reactivating explosive-laden carbons to date is in rotary kilns other processing techniques are discussed in this report.
