| 121 | Electrodeless plasma torch apparatus and methods for the dissociation of hazardous waste | US746419 | 1991-08-16 | US5288969A | 1994-02-22 | Alfred Y. Wong; Andras Kuthi |
| A system and method are provided for the non-thermal destruction of hazardous waste material using an electrodeless inductively coupled RF plasma torch. The waste material is combined with a controllable source of free electrons, and the RF plasma torch is used to excite the free electrons, raising their temperature to 3000.degree. C. or more. The electrons are maintained at this temperature for a sufficient time to enable the free electrons to dissociate the waste material as a result of collisions and ultraviolet radiation generated in situ by electron-molecule collisions. The source of free electrons is preferably an inert gas such as argon, which may be used as both the waste material carrier gas and the torch gas. | ||||||

| A method of immobilizing a contaminant comprising mixing the contaminant with a reaction partner that is capable of chemically interacting with the contaminant to form a water-insoluble reaction product, the reaction partner being mixed in the form of a hydrophobic solid preparation, which is either obtained by grinding the reaction partner with an inert material and treating it with a hydrophobing agent or which contains the educt or reaction product of a dispersion by chemical reaction preliminarily treated with a hydrophobing agent, the mixing being conducted to form a soil or soil-like material with cohesive constituents of a clay-like structure. | ||||||
| 123 | Plasma torch furnace processing of spent potliner from aluminum smelters | US868024 | 1992-04-13 | US5222448A | 1993-06-29 | George W. Morgenthaler; Jeffrey L. Struthers; George W. Carter |
| Spent potliner from aluminum reduction cells includes carbon, inorganic brick and refractory material, and fluoride, sulfur, and cyanide compounds, and is considered hazardous. It is treated by introducing it into a vessel, and exposing it to the heat of a plasma torch at a temperature of at least 1000.degree. C. As a result, carbon is gasified and converted to combustible carbon monoxide or hydrocarbons, or to carbon dioxide; inorganic material is melted form slag; fluoride compounds are melted, vaporized, or reduced to gaseous HF; cyanide compounds are destroyed; and all other materials, including sulfur compounds, are either melted or gasified. As a result, the spent potliner is rendered non-hazardous, and the quantity of remaining slag has both its solid volume and mass substantially reduced by a factor of at least 1.5:1 in mass and at least 3:1 in volume relative to the input spent potliner. The process allows gaseous fluoride compounds to be captured and thermal energy produced in the process to be extracted. The molten slag material produced within the vessel is removed from the vessel, and cooled to form a solid slag which is substantially free of cyanide compounds, resistive to leaching, and safe for disposal. The slag has commercial utility. Combustible carbon compounds can be captured and used. When carried out at an aluminum smelting site, adequate electrical power is readily available, and there is an in situ demand for recovered fluoride compounds, combustible gases, and extracted heat. | ||||||

| 127 | Hazardous waste incinerator using cyclotron resonance plasma | US282838 | 1988-12-08 | US4909164A | 1990-03-20 | J. Leon Shohet; David T. Anderson |
| A hazardou waste incinerator which utilizes a cyclotron resonance plasma. The plasma is generated by introducing vaporized hazardous material and a feed gas into a vacuum chamber. The chamber has a magnetic field source and an electromagnetic radiation source. The cyclotron resonance plasma is produced by the resonance that occurs when the frequency of the electromagnetic radiation is set equal to that of the gyration of electrons or other charged particles in the magnetic field according to the formula: F.sub.res =(1/2.pi.)(qB/m) hertz Where q is the charge of the electron or ion, B is the strength of the magnetic field and m is the mass of the electron or ion. The strength of the electromagnetic radiation is adjusted so that the flowing gases are ionized, forming a plasma. During the reaction, the charged particles collide with neutral particles, providing both ionization and fragmentation (the breaking up of high-mass molecules into lower mass fragments). When electromagnetic radiation is applied at the ion cyclotron resonance frequency for a particular charge-to-mass ratio, ions of this ratio are accelerated outward and colilde with other particles in the plasma. This can result in further fragmenting of these ions or other particles or the ions will be selectively expelled or collected at the outer boundaries of the reactor. | ||||||

Periodically the concentration of the hydrogen peroxide is increased for a short time sufficiently to be toxic to the biota at or relatively adjacent to the site of introduction, thereby increasing the permeability of the formation at or adjacent to the site of introduction. | ||||||

| This invention relates to thermo-chemical remediation and decontamination of sediments and soils contaminated with organic contaminants as well as inorganic materials with subsequent beneficial reuse. Novel environmentally stable products of commercial value are produced when certain additives such as calcium and metal oxides are mixed with the contaminated materials. In the process, the mixture is heated to 1150 DEG C. DIFFERENCE 1500 DEG C. to produce a molten reaction product with at least part of an excess amount of oxygen mixture or air is continuously bubbled through the melt in order to provide mixing and achieve high thermal destruction and removal efficiencies of the organic contaminants. The melt is then quickly quenched in moist air, steam, or water to avoid the transformation of the amorphous material into crystals. The inorganic contaminants such as chromium, nickel, zinc, etc. are incorporated and completely immobilized within the amorphous silicate network. The amorphous material can be pulverized to yield a powder which evinces cementitious properties either by reaction with alkali solution or by blending it with other materials to produce blended cements. The compressive strengths of the concretes made from the powder of the subject invention and blends thereof are comparable to, or greater than the ASTM requirements for general purpose concrete applications. The powder of the subject invention, blended cements, and concrete/mortar derived therefrom also easily pass the EPA TCLP leach test to achieve environmental acceptability. | ||||||
