Abstract:
A process for destroying waste using an electric arc gasifier , comprising the steps of:forming an electric arc in a heating chamber between a mobile electrode and a fixed electrode,injecting a primary fluid into said heating chamber through said electric arc, thereby forming a plasma, wherein said primary fluid is a material selected from the group consisting of gaseous hydrocarbons, argon and nitrogen;positioning each of said electrodes in response to a system control device, wherein said system control device allows for an adjustment of each of said electrodes based on a flow rate of said primary fluid and a system operating pressure;mixing a secondary fluid into said plasma forming a mixture of gases, solids, and liquids at a high temperature above 1,400.degree. C., wherein said secondary fluid is a waste and a carrier gas;passing said mixture of said gases, said solids, and said liquids into said fixed electrode, wherein said mixture of said gases, said solids, and said liquids is accelerated into a mixing chamber by a sudden expansion of said gases;injecting a tertiary gas into said mixing chamber at pressures up to 150 psi, thereby mixing said mixture of said gases, said solids, and said liquids with said tertiary gas;providing a collection vessel, wherein said gases of said mixture are separated from said liquids and said solids of said mixture; and,processing said gases.
