Abstract:
A method for destruction of hazardous gaseous material, comprising:a) providing a chamber having a longitudinal axis and longitudinally extending electrically conductive sidewalls, at least one sidewall having a longitudinally extending gap that interrupts a current path through the sidewalls transverse to the longitudinal axis;b) providing an axially-extending array of current-carrying conductor paths that at least partially encircle the chamber and are transverse to the longitudinal axis of the chamber;c) providing the hazardous gaseous material in the chamber at a controlled pressure; andd) providing high-frequency current in the conductor paths in a magnitude to magnetically induce ionization of the gaseous material in the chamber and form a plasma sheath that surrounds and extends along the longitudinal axis and conforms to the sidewalls of the chamber in which the hazardous gaseous material is converted to a non-hazardous form.
