초록 ▼

A process for melting material to be treated includes placing material to be treated in a container that may include an insulating lining, heating the material to be treated and melting the material to be treated, preferably allowing the melted material to cool to form a vitrified and/or crystalline mass, and disposing of the mass. The mass is either disposed while contained in container or removed from container after cooling and disposed. Insulating lining may comprise one or more layers of a thermal insulating material, one or more layers of refractory material, or a combination thereof. The material to be treated may be heated by placing at least two electrodes in the material to be treated and passing a current between the electrodes, or alternatively, by placing at least one heating element in the material to be treated and passing heat into the material to be treated.

What is claimed is: 1. A process for melting materials to be treated, the process comprising: providing a container having an interior portion and an exterior portion wherein the interior portion can hold materials therein; placing a first and a second insulating layer over the interior portion of the container, wherein a slip form is used to place the first or second insulating layer into the container; placing hazardous and/or contaminated and/or waste materials to be treated into the interior portion of the container, wherein the container does not comprise a region formed in the ground and the container can withstand temperatures of at least about 1400 degrees C. without significant degradation of the container; heating the hazardous and/or contaminated and/or waste materials to be treated in the container at a temperature of at least about 1400 degrees C. until the materials to be treated melt to create melted hazardous and/or contaminated and/or waste materials; allowing the melted hazardous and/or contaminated and/or waste materials to cool in the container to create a vitrified hazardous and/or contaminated and/or waste material; and disposing of the vitrified hazardous and/or contaminated and/or waste material wherein the disposing is capable of being either discarding the container with the vitrified material therein or removing the vitrified material from the container such that the container can be used in another melting process. 2. The process of claim 1, further comprising placing a liquid impermeable liner over the second insulating layer in the interior portion of the container. 3. The process of claim 1, further comprising removing the slip form. 4. A process for melting materials having hazardous and/or contaminated and/or waste substances, comprising: providing a container having an interior surface forming one or more side walls and a base; lining the container interior surface with a first insulation material; lining the container interior surface with a refractory material; placing sand between the container and the refractory material; placing materials including the hazardous and/or contaminated and/or waste substances into the container, wherein the container can withstand temperatures of up to 2000 degrees C. without significant degradation of the container; heating the materials in the container to a molten state; vitrifying the molten materials without removing molten materials from the container to form a vitrified product in the container that contains at least a portion of the hazardous and/or contaminated and/or waste substances immobilized therein; and wherein the container may be discarded with the vitrified product therein or the container may be used for another melting process. 5. The process of claim 4, wherein the refractory material comprises concrete. 6. A process for melting materials having hazardous and/or contaminated substances, comprising: providing a container having an interior portion, the container being capable of withstanding temperatures of up to 2000 degrees C. without significant degradation of the container, wherein the container does not comprise a region formed in the ground; placing a refractory layer comprising cement on the interior portion of the container before placing substances to be treated into the container; placing sand between the interior portion of the container and the refractory layer before placing the substances to be treated into the container; placing the substances to be treated into the container; placing at least two electrodes located in the substances to be treated and passing a current between the at least two electrodes to heat the substances in the container to a molten state; vitrifying the molten materials without removing molten materials from the container to form a vitrified product in the container that contains at least a portion of the hazardous and/or contaminated substances immobilized therein; and discarding the container with the vitrified product therein or removing the vitrified product from the container and using the container for another melting process.
