摘要： Embodiments of this disclosure relate to tissue digestion and, more particularly, to methods and apparatuses for varying the number, size, and/or location of one or more tissue compartments within a digestive fluid vessel. Some examples include partitions that may be selectively positioned within a vessel (and may be selectively removable from the vessel) to create one or more tissue compartments. The partitions may be positioned, repositioned and rearranged within the vessel to form one or more tissue compartments. The partitions may be solid or include apertures, and may be oriented in horizontally and/or vertically. Alternate embodiments include one or more selectively closeable apertures that permit digestive fluid to circulate along alternate pathways, which can permit tissue digestion with reduced digestive fluid levels. Still further embodiments include baskets that are selectively positionable within the tissue digester. The baskets may also include one or more selectively positionable and/or repositionable partitions.

摘要： A mobile destruction apparatus for use with oil contaminated with a toxic organic pollutant material includes a housing, which defines a first heating combustion chamber for heating the oil to generate a toxic fluid using a first burner connected thereto. The apparatus includes a rotating transition cylinder that defines a drying chamber, which is in fluid communication with the combustion chamber to receive the toxic fluid. The cylinder includes an amount of a desiccant material to dry the toxic fluid. A second heating destruction chamber is provided downstream of the cylinder to heat the toxic fluid to substantially convert it and destroy it into an inert fluid, which exhausts from the apparatus. A method of destructing toxic contaminants from contaminated oils is also described.

摘要： A method of reducing the volume of a mixture of filter fibers and a powder-form ion-exchange resin, produces a waste product that is particularly suitable for ultimate disposal. A solvent which dissolves the filter fibers is added to the mixture and a mixture which is thus formed is first dried and then given an additional heat treatment.

摘要： A method of containing hazardous and toxic wastes includes the steps of irporating the dried waste, in a salt form, in melted polymer, such as asphalt, and forming the waste salt and asphalt blend into aggregate pellets. The pellets are coated with a powdered coating material that is compatible with a portland cement-based mortar or other cementitious material which is used. The coated particles are mixed with mortar to form a polymer-aggregate concrete and cast into wasteforms for storage or burial. If it is desirable to produce a waste form with a continuous layer of mortar on the exterior of the concrete monolith the mold can be placed on a turntable and spun, or otherwise exposed to a centrifugal force to force the mortar to the outside of the mold. Centrifugal separation is possible because the polymer-waste mixture typically has a specific gravity near 1.5 while that of the cementitious mixture is typically greater than 2.0.

摘要： A method and apparatus are disclosed wherein toxic and nuclear waste are pumped in a metered fashion or introduced through a sealing door into a plasma region. The plasma region is generated in a sealed chamber by a radio frequency plasma torch. In the plasma region the toxic waste is atomized and ionized. The recombining of the atomized and ionized molecules is managed in the sealed reaction chamber to yield environmentally neutral products. Encapsulation material that is either introduced into the process chamber with the waste or is resident in the process chamber encapsulates radioactive or heavy metal atoms in a glassy stone like material. This encapsulating renders the atoms environmentally neutral. The flow of material in and out of the reaction chamber are regulated carefully. The radio frequency power level is also carefully controlled. These controls insure the neutrality of the recombining products. The fluids exiting the chamber are filtered before release, to insure environmental neutrality.

摘要： A method of oxidatively decomposing a radioactive ion-exchange resin is described, the method comprising oxidatively decomposing a radioactive ion-exchange resin containing an anion-exchange resin with hydrogen peroxide used as an oxidizing agent in the presence of iron and copper ions used as catalysts, wherein the weight ratio of hydrogen peroxide to the ion-exchange resin, that is the ratio of the net weight of hydrogen peroxide to the dry weight of the ion-exchange resin containing an anion-exchange resin, is held to be no higher than 17 and the pH of the reaction system is adjusted to be within the range of 0.5 to 6, or citric acid ions are preliminarily adsorbed on the radioactive ion-exchange resin before it is subjected to decomposition treatment or citric acid ions coexist with the radioactive ion-exchange resin in the oxidatively decomposing system, and an apparatus used for conducting the method is also described.

摘要： Wastes, in the form of liquids, solids and slurries, are converted to a mixture of a gas and an inorganic ash by introducing the waste as a finely atomized spray into a zone heated by means of a hot gas. Contact of the spray particles with the hot gas results in drying the waste and calcining and combusting the dried waste. The process is particularly useful with wastes containing hazardous materials such as radioactive substances.
