Laboratory Study of Pyrolysis of Explosive Contaminated Waste.
Abstract
Samples of mixed waste material and mixed waste material contaminated with levels of one-half percent, one percent, and two percent TNT were pyrolyzed at 650 C in a 15.2 cm tube furnace. The waste material was typical of contaminated waste disposed of by Army Ammunition Plants by either open air burning or incineration. The products of pyrolysis were all collected and analyzed. From the data, material and energy balances for each pyrolysis experiment were determined. Based on these experiments, 68 to 74 per cent of the energy content of the input feed on a dry basis can be recovered in the char and oil, which are storable and transportable fuels. The data show that the energy content of the gases is in the range of 16 to 22 percent of the energy content of the input feed on a dry basis. The gases would have to be utilized on site. Preliminary experiment with TNT contaminated waste did not produce any evidence of any explosion hazard in the thermal decomposition of the waste at 650 C. In the four pyrolysis experiments at 650 C in the 15.2 cm tube furnace there was no evidence of any explosion hazard with the contaminated waste. The data do not indicate that there would be any significant environmental impact from the pyrolysis of TNT contaminated waste. (Author)
