    摘要： 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.

    摘要翻译： 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。

    摘要： A method for producing flake particles by projecting a continuing stream of molten material upon the surface of a rotating generally circular, heat extracting drum, having a serrated edge with each serration comprising a radial surface and an angularly disposed connecting surface from the base of one radial surface to the peripheral extremity of the adjacent radial surface; and rotating the heat extracting drum at a speed relative to the size and shape of the serrations and relative to the rate of molten material projection to form a discrete flake particle on each angularly disposed surface; followed by removing each particle from the surface after each particle is at least partially solidified; and cooling the particles in a surrounding atmosphere.An apparatus for producing flake particles comprising means for projecting a stream of molten material upon a rotatable heat extracting drum member having a serrated generally circular peripheral edge, with each serration having a radial surface and an angular surface connecting the base of one radial surface with the peripheral extremity of the next radial surface; and a shaft supporting the heat extracting member for rotation at a controlled speed; with means responsive to the rate of projection of the molten material upon the serrated surface of the heat extracting member to control its speed of rotation relative to the rate of projection of molten material.
