Abstract

For the management of refractory hazardous wastes, an innovative technology emerged recently is the application of ultra high temperature plasma. The preliminary study on the destruction of Freon 12 by ICP (1-2KW) under a joint program between Xiamen Univ. and Hong Kong Baptist Univ. showed that the ICP technology indeed holds a great potential for the hazardous wastes management. The destruction efficiency is better than 99.9999%.

With and without presence of Freon 12, Ar (I) excitation temperatures are measured by Boltzmann plot method and electron number densities are measured by H (beta) line broadening method. Above the load coil, the excitation temperatures and electron number densities decrease with increasing amount of Freon 12 presented in the central channel of ICP discharge, but inside the load coil region, excitation temperatures affected little by the addition of Freon 12.

The conclusion of thermal pinch is made from this phenomenon.
