20060167330 - System and method for chemical decontamination of radioactive material: A method for chemically decontaminating radioactive material. The method includes reducing-dissolving step for setting surface of radioactive material in contact with reducing decontamination liquid including mono-carboxylic acid and di-carboxylic acid as dissolvent; and oxidizing-dissolving step for setting the surface of the radioactive material in contact with oxidizing decontamination liquid including...

20060167331 - Single stage denitration: A system and method using fluidizing gas optionally augmented by oxygen for reducing nitrogen oxides present in a wide variety of waste materials. The system includes a single reaction vessel, or optionally multiple reaction vessels, providing multiple reaction bed zones in fluid communication. Reduction takes place quickly when steam or...

20060161038 - Device and method for converting solid waste to gas: A device for converting solid waste to gaseous form. The device includes a chamber for holding waste material and molten eutectics. The chamber has at least one opening for receiving the waste material into the molten eutectics. An oxygen supply and an ozone supply bring oxygen and ozone into the...

20060149118 - Process and plant for the hydrothermal treatment of asbestos and/or asbestos-containing materials in supercritical water: Herein described is a process for the hydrothermal treatment of asbestos and/or materials containing asbestos in supercritical water (Supercritical Water, SCW), that provides for the withdrawal (3) of water from a tank (2), the transformation (5) of the water in supercritical water, the reaction of the supercritical water with asbestos...
