摘要： A process for removing PCDD's and PCDF's from paper mill sludge is provided. The process comprises combining the sludge with an oxidant and then oxidizing the sludge under supercritical or near supercritical conditions to destroy the PCDD's and PCDF's. Using this process, destruction efficiencies of greater than 98% have been achieved for 2,3,7,8-TCDD, which is reportedly the most toxic of the dioxins.

摘要： A process for treating solid substantially non-volatile wastes contaminated with a heat sensitive contaminant is disclosed. The wastes are heated to form a liquid slag. The liquid slag is held at elevated temperature until at least a portion of the contaminating components have either decomposed or evolved from the melt as a gas. The slag is subjected to cooling and the contaminating compounds are bound or encapsulated into a solid glassy slag. The process is particularly suitable for handling fluoride and cyanide contaminated aluminum smelting wastes such as spent potliner material. It is advantageous to add silica to such wastes. The residue from the slagging reaction is a glassy solid sodium metal silicate matrix such that the fluoride residues remaining in the wastes are encapsulated. The amount of silicate blended with the feed material is selected to substantially tie up all of the sodium remaining in the residue after slag melting and is typically 7.5 to 50 weight percent of the feed. The resulting solid, glassy slag material produced is not hazardous to health and is essentially inert to the environment.

摘要： An accelerated process for the complete neutralization of acid wastes, the destruction of concrete and/or the denaturation of asbestos-containing materials (ACMs) includes forming a slurry or suspension by submerging in the acid solution the concrete and/or asbestos-containing materials (ACMs); the concrete and/or asbestos-containing materials (ACMs) cause the acid wastes neutralizing chemical reactions in the slurry or suspension and, at the same time, the destruction of concrete and/or the denaturation of asbestos-containing materials (ACMs). Simultaneously to the chemical reactions, the slurry or suspension is subjected to hydrodynamic cavitation, preferably using an apparatus capable of producing and managing three types of simultaneous controlled cavitation acting in the same space volume, accelerating the chemical reactions taking place in the slurry due also to the simultaneous presence of acid, concrete and/or asbestos-containing materials (ACMs). The concrete and/or asbestos-containing materials (ACMs) are preferably ground and polarized prior to be submerged in the acid solution to form the slurry. The polarization take place, for the really first time, with a cold plasma torch. In addition the slurry or suspension is preferably subjected to hydrothermal treatment, preferably using a reactor which ensures the preservation of the constancy of the ideal physical parameters for the reaction in the physical chemical environment. In this reactor are additivated chemicals, hydroxyapatite and biological substances that have binder/chelating power especially on metals contained in asbestos, especially on magnesium, in order to prevent its reformation. Recovering, at the end of the process, inert secondary raw materials (SRMs) that are non-hazardous to the environment and human health. In addition, this process could be used to produce molecules that are important intermediates of the subsequent reactions/processes, leading to the formation of salts/compounds used as dietary supplements and also in important environmental remedies such as polluted water reclamation and the treatment of heavily polluted soils.

The method further comprises removing a produced steam and hydrogen mixture from the reactor via a steam-gas unit and droplet separator into a wastewater condenser unit and a gas drainage pipe, and venting suspended solids through a bottom part of the reactor into a solids collector unit. The method then provides the steps of repeating the batch processing cycle after it has terminated; and monitoring and controlling the temperature and pressure inside the reactor via an Automatic Process Control System (APCS) during all steps.
