    Abstract: For disposal of waste material including water, volatile components and vitrifiable components, the waste material is heated in a dehydrator to remove the water, heated in a high-temperature dryer to vaporize hydrocarbon liquids, and then fed to the focus point of a primary plasma reactor where plasma arc jets are focused on the surface of a pool of the vitrifiable components. At the focus point the vitrifiable components are melted, and the volatile components are volatized. The melted vitrifiable components are received in a quench chamber where they solidify on a quench roller and are broken into chips and delivered to a receiving area. Heat from the quench chamber is transferred to the dehydrator and high-temperature dryer. The hydrocarbon liquids and volatized components are fed to a secondary plasma reactor where they are disassociated into their elemental components. The effluent from the secondary plasma reactor is scrubbed to remove hydrogen sulfide and halogens, and residual components, together with excess water vapor, are extracted in an absorber and fed back for further processing in the secondary plasma reactor.

    Abstract translation: 为了处理包括水，挥发性组分和玻璃化组分在内的废料，将废料在脱水器中加热以除去水，在高温干燥器中加热以蒸发烃类液体，然后进料到初级等离子体的聚焦点 反应堆，其中等离子体电弧喷射集中在可玻璃化组件的池的表面上。 在焦点处，可玻璃化组分熔化，挥发性组分挥发。 熔化的可玻璃化组件被接收在淬火室中，在骤冷室中，它们在骤冷辊上固化并分解成碎屑并输送到接收区域。 来自骤冷室的热量转移到脱水机和高温干燥器。 碳氢化合物液体和挥发成分进料到二次等离子体反应器中，在其中它们与其元素组分分离。 洗涤来自二次等离子体反应器的流出物以除去硫化氢和卤素，并将剩余组分与过量的水蒸气一起提取在吸收器中并反馈以在二次等离子体反应器中进一步处理。

    Abstract: UNWANTED EXPLOSIVES AND PROPELLANTS ARE DESTROYED IN A SAFE NON-POLLUTING MANNER BY BEING CONTRACTED WITH A HOT MOLTEN SALT CONTAINING AS ESSENTIAL REACTIVE COMPONENT ALKALI METAL CARBONATE OR HYDROXIDE OR MIXTURES THEREOF. SOME OF THE RESULTING DECOMPOSITION PRODUCTS THAT WOULD ORDINARILY BE RELEASED AS ATMOSPHERIC POLLUTANTS REACT WITH OR ARE RETAINED IN THE MELT. ANY COMBUSTIBLE MATTER PRESENT IN THE MELT MAY BE FURTHER REACTED BY USE OF OXIDATIVE MOLTEN SALTS ALONG OR IN COMBINATION WITH OXYGEN ADDED TO THE MELT. FORMED GASEOUS PRODUCTS MAY BE TREATED IN A SECOND REACTION ZONE TO COMPLETE OXIDATION OF ANY COMBUSTIBLE MATTER PRESENT BEFORE DISCHARGE OF THE GASES TO THE ATMOSPHERE. THE REACTIVE COMPONENT OF THE TREATED MELT MAY BE REGENERATED, OR THE MELT MAY BE DISPOSED OF, PREFERABLY BY REACTION WITH LIME IN AN AQUEOUS OR MOLTEN MEDIUM TO FORM A WATER-INSOLUBLE CALCIUM SALT RESIDUE. PARTICULARLY EFFECTIVE AND PREFERRED REACTED MOLTEN SALTS ARE THE NAOH-KOH AND LI2CO2-NA2CO2-K2CO2 EUTECTIC MIXTURES.

    Abstract: A device for destroying a chemical agent is described. The device includes a self-contained, portable pressure vessel which is dimensioned to accommodate an artillery shell, and a heat-generating component within the pressure vessel. The heat-generating component is capable of providing a pyrolytic, exothermic reaction capable of destroying the chemical agent and artillery shell. A process for destroying a chemical agent which includes placing a chemical artillery shell within the pressure vessel, securing the pressure vessel closed, and igniting the heat-generating component inside the pressure vessel to generate a pyrolytic, exothermic reaction capable of destroying the chemical agent and artillery shell is also described.

    Abstract: There are disclosed processes for destructing a toxic chemical including the steps of mixing the toxic chemical with a liquid phase formed by an aqueous mixture of water and an ionic liquid or molten salt which is miscible with water, the ionic liquid or molten salt comprising a tertiary amine group or quaternary ammonium group; and contacting the toxic chemical in the liquid phase with the ionic liquid or molten salt so as to decompose the toxic chemical.

    Abstract: A method of destructing a toxic chemical, comprising the steps of mixing said toxic chemical with a liquid phase formed by an aqueous mixture of water and an ionic liquid or molten salt which is miscible with water, said ionic liquid or molten salt comprising a tertiary amine group or quaternary ammonium group; and contacting said toxic chemical in said liquid phase with said ionic liquid or molten salt so as to decompose said toxic chemical. The ionic liquid or molten salt comprises a tertiary amine group or quaternary ammonium group. The dispersion or solution further contains at least one oxidizing agent and a donor of hydrogen bonds. Decontamination of contaminated surfaces and decomposition of toxic substances are achieved by using environmentally friendly, non-toxic solvents and reactants which yields reaction products which are substantially non-harmful or even non-toxic.
