The use of experiments and modeling to evaluate incineration of chemical warfare agent simulants bound on building materials
In the event of a terrorist attack with chemical warfare agents (CWAs), large quantities of materials, both indoor and outdoor, may be treated by thermal incineration during the site remediation process. CWAs in general are not particularly thermally stable and decompose readily in a high temperature combustion environment. Potential difficulties exist, however, in thermally processing waste building materials from a post-CWA event site remediation due to the refractory nature of many materials found inside and outside buildings, and the potential impacts that waste packaging at the site may have on the behavior of these materials and residual agent destruction in combustion systems. This paper reports on a study to examine the thermal decomposition of surrogate CWAs (in this case, Malathion) in a laboratory reactor, analysis of the results using reactor design theory, and subsequent scale-up of the results to a computer-simulation of a full-scale commercial hazardous waste incinerator processing ceiling tile contaminated with residual Malathion. The heating rates that the reactor was subjected to were based on previously determined heating rates of wet ceiling tile in a pilot-scale rotary kiln incinerator simulator, and are intended to simulate the thermal processing of building materials containing trace amounts of CWAs.
