ABSTRACT

Waste: all industrial productions generate wastes which must be eliminated unless degrading the environment. In order to reduce the waste volumes, CEA (the French Atomic Energy Agency) has developed and patented a new process based upon the use of inductive plasma torch. The process is specialized in degradation of liquid wastes, pure or in mixture, such as organic or organic-halogen one. The goal of this development was, to achieve a complete destruction of products but also to control the atomic recombination in order to reject only non-toxic off-gases. Demonstration of the relevance is presented here by chloroform destruction capability.
After presentation of the process, experiments with chloroform are presented The global results are discussed showing the good destruction efficiency and correct off gases composition: the wastes have been completely destroyed, only CO2 and H2O have been formed without any toxic compound or soot formation while the chlorine is trapped by soda and transforms in mineral salt. The final aim of this study is to develop a clean process for treatment of radioactive organic halogen compounds. A small scale reactor is being studied to prove the capability of the process for radioactive organic halogen liquid waste destruction.
