摘要： The present invention relates to a method and a plant for treating carbon-containing waste that may comprise mineral fillers and/or potential contaminants.
This method comprises: preparing a molten glass bath at a temperature between 1100° C. and 1600° C.; loading the waste to be treated into said molten glass bath; injecting an oxidizer and optionally a fuel under pressure into said molten glass bath by means of at least one hose, one end of which is immersed in said bath, said oxidizer being introduced in a molar amount less than the molar amount of the carbon-containing compounds, thus causing combustion of said waste and generation of hot synthesis gases; implementing heat exchange between a heat-transfer fluid and the hot synthesis gases in conditions allowing simultaneous recovery of at least part of their heat energy and at least part of the heat energy released by their combustion, air being injected sequentially into said gases during said heat exchange to cause self-ignition of the mixture of said gases and air, each injection increasing the degree of combustion.-

摘要： A sealing system for isolating the environment inside a vitrification container from the outside environment comprises a vitrification container with a lid. The lid comprises two or more electrode seal assemblies through which two or more electrodes may be operatively positioned and extend down through the lid into the vitrification container. The electrodes may move axially up and down through the electrode seal assemblies or lock into place. The electrode seal assemblies each comprise a housing having two halves with recessed ring grooves. Sealing rings with a split may be placed into the grooves. Gas galleries may be machined or cast into the housing such that they are adjacent to the ring grooves. The gas galleries distribute gas onto the external faces of the sealing rings causing a change in pressure resulting in the sealing rings compressing onto the electrodes and forming a seal.

摘要： An underground ventilated system for storing nuclear waste materials. The system includes a storage module having an outer shell defining an internal cavity and an inner shell. A majority of the height of the outer shell may be disposed below grade. The outer shell may include a hermetically sealed bottom. First and second canisters are positioned in lower and upper portions within the cavity respectively in vertically stacked relationship. A centering and spacing ring assembly is interspersed between the first and second canisters to transfer the weight of the upper second canister to the lower first canister. The assembly may include centering lugs which laterally restrain the first and second canisters in case of a seismic event. A natural convection driven ventilated air system cools the canisters to remove residual decay heat to the atmosphere. In one non-limiting embodiment, the shells are made of steel.

摘要： The present invention provides systems, methods and devices for storing and/or disposing of hazardous waste material such as calcined material. In certain embodiments, the system comprises a filling nozzle having a valve body having a distal end and an outer surface, the outer surface proximate the distal end being configured to sealingly and removeably couple to an inner surface of a filling port of the container. In certain embodiments, the method comprises (a) coupling an outer surface of a filling nozzle with an inner surface of a filling port of a container to form a first seal (b) adding hazardous waste material into the container (c) decoupling the filling port from the filling nozzle and (d) inserting a fill plug into the filling port, the fill plug forming a second seal with the inner surface of the filling port, the second seal being distally spaced from at least a portion of the first seal with respect to the container.

摘要： A method for treating and disposing of mercury—from mercury-contaminated waste—includes recovering high-purity mercury (e.g., greater than about 99.0 wt. % elemental Hg) from the mercury-contaminated waste. The high-purity mercury is converted to mercuric sulfide (HgS). The mercuric sulfide (HgS) is intermixed with a polymer-based material to form an encapsulated mercury material. The encapsulated mercury material is disposed within a sealed waste container. The sealed waste container is disposed of at a landfill site. Also disclosed is a mercury-including waste product that comprises pellets. The pellets comprise mercuric sulfide within a polymer material.
