Abstract

A liner system for in-container vitrification that can withstand high temperature is critical to the overall in-container vitrification process. A treatment vessel comprising a treatment vessel having an inner and outer wall wherein the inner wall defines a void therein. An insulation layer is deposited inside the void so as to create an annulus between the inner wall of the treatment vessel and the insulation layer to allow air or liquid to flow around the melt to facilitate the dissipation of the heat from the entire melting process. Next a layer of refractory material best suited to inhibit the transmission of heat from the melt is deposited within the insulation layer and is in thermal contact with the melt material. More specifically, commercial 'roll-off boxes' lined with insulating layer comprising carbon based materials, insulation board, graphite based materials and any combination thereof in combination with refractory materials such as sand, bricks, concrete and combinations thereof are provided in this invention.
