Document Type and Number:
Japanese Patent JP2001506739
Kind Code:
A
Abstract:
A novel process and apparatus for the thermal partitioning of heterogeneous feedstock (11) for the production of a metal product, a glass ceramic product and a gaseous product. The process includes the capability for thermal treatment of hazardous waste as defined by the Environmental Protection Agency (EPA) which also contains radioactive isotop es in some cases (mixed waste as defined by the Department of Energy) and the production of stable long-lived products as a result of treatment. More specifically, this invention relates to a novel process and apparatus whereby an input feed stream (9) of a widely heterogeneous nature in the descriptors of physical form, combustibility, chemical content, and particle size and contaminated with varying concentrations of hazardous components and/or radioisotopes is treated in a direct current graphite electrode arc melter (4) with a contiguous thermal oxidizing reactor (5) for the production of a metal product, a basalt-like glass ceramic product and a fully combusted offgas. The apparatu s described incorporates an offgas fast quench configuration (17) for the minimization of dioxin formation and subsequent ease of cleansi ng of the offgas stream.
