ABSTRACT:
For disposal of waste material including water, volatile components and vitrifiable components, the waste material is heated in a dehydrator to remove the water, heated in a high-temperature dryer to vaporize hydrocarbon liquids, and then fed to the focus point of a primary plasma reactor where plasma arc jets are focused on the surface of a pool of the vitrifiable components. At the focus point the vitrifiable components are melted, and the volatile components are volatized. The melted vitrifiable components are received in a quench chamber where they solidify on a quench roller and are broken into chips and delivered to a receiving area. Heat from the quench chamber is transferred to the dehydrator and high-temperature dryer. The hydrocarbon liquids and volatized components are fed to a secondary plasma reactor where they are disassociated into their elemental components. The effluent from the secondary plasma reactor is scrubbed to remove hydrogen sulfide and halogens, and residual components, together with excess water vapor, are extracted in an absorber and fed back for further processing in the secondary plasma reactor.
