The cost of off-gas treatment during remediation of hazardous waste sites can typically increase the cost by 50% or more. This research is targeted towards developing a simple cost effective technology to destroy chlorinated organic solvents in the vapor phase. The process uses a dry chemical at a slightly elevated temperature. The research involves testing of a variety of related dry chemicals in a temperature range of 500?C or less. The thermodynamics have been evaluated for the destruction of several chlorinated solvents. The very large negative value for the Gibbs Free Energy of Formation, deltaG?, on the order of -1,000kj/mole, for each reaction indicates that the reactions should occur spontaneously. The kinetics, however, are unknown and will be studied during the conduct of this research.
