Abstract
The destruction of parts per million (ppm) levels of volatile organic compounds in a dry air stream by high–energy electron–beam irradiation has been investigated in a pilot plant at the University of Tennessee Space Institute, Tullahoma, Tennessee. In a series of experiments, dry air contaminated with various VOCs in the concentration range of 50–1000 ppm were treated in the UTSI pilot plant to determine the extent of destruction at various electronbeam dose levels.
The destruction removal efficiency was determined as a function of the electron beam irradiation dose. The results suggest a charge transfer reaction as the major decomposition mechanism. A theoretical foundation of the process, along with a simple first–generation reaction kinetics model, a summary of the results from the pilot plant flow reactor, and a preliminary cost analysis for a fullscale detoxification plant using currently available electronbeam gun technology are presented in this paper.
