Arc Plasma Torch

In situ plasma magmavication is a powerful and expedient technique for melting soil that subsequently cools to form a glassy igneous rock. A nontransferred arc plasma torch provides temperatures exceeding 4000°C that can be positioned within boreholes as a means of ground improvement or for environmental restoration of contaminated soils. The process is similar to in situ vitrification by embedded graphite electrodes, yet the nontransferred arc is a considerably more efficient process. The artificial rock can be left in place or, alternatively, may be exhumed and stored. The effectiveness of plasma remediation on uncontaminated and contaminated kaolin was investigated through a preliminary series of laboratory chamber tests with small dosages of chemical, biological, and nuclear surrogates. It is believed that the process pyrolizes organic contaminants, while locking the inorganic contaminants within the glass matrix. Measurements in compressive strength, stiffness, porosity, and mass density verified the transformation of soil to rock with improved material characteristics.
