THERMAL PLASMA TREATMENT TECHNOLOGIES FOR HAZARDOUS WASTES REMEDIATION

摘要

The purpose of this special physical-chemical process encompassing the behaviour of high temperature plasmas is the complete dissociation, of semi-organic and/or organic molecules classified as dangerous, including: Bio Hazardous Molecules, Nerve Gases (NG), Bio-organic Molecules and Biological Elements (bacteria, DNA-RNA viruses, prions). The process can be applied to sites containing contaminating materials or directly to polluted areas in civilian or military industrial plants or laboratories. The process relies on physical -chemical and magneto-dynamic techniques applied to ionized gas together with the introduction of atomic elements such as Lanthanides, Yttrium, Iron, Helium and Hydrogen within the plasma. The process relies on techniques of plasma creation through RF (Radio Frequencies) generators, coupled with Magneto Gas Dynamics (MGD) and Magneto Hydro Dynamics (MHD) complexes acting as a motor and/or generator of plasma in confined hot regions of the plasma. As the sections can be toroidal, linear, or hybrid, the MHD-MGD motor generator coupling allows the recycling and confining of the atomic ionized elements, while keeping a high gradient of temperature (T°K: 4, 000- 7,000 K) for several minutes (between 1 and 3 minutes according to the molecules to be dissociated).
