A method for treatment of halogen-containing waste material, in particular PVC-containing waste material, is disclosed. The waste material is heated in a decomposition step in a reaction zone in a substantially closed system essentially without addition of water to a temperature between 150 and 750° C., preferably 250-350° C., in the presence of a halogen-reactive compound selected from alkali and alkaline earth metal hydroxides, alkali and alkaline earth metal carbonates and mixtures thereof, so as to establish a controllable autogenous pressure substantially above atmospheric pressure, in a sufficient reaction time to convert essentially all halogen present in the waste material to alkali or alkaline earth metal halides. The closed system preferably also has a condensation zone, where water vapor and volatile compounds liberated from the waste material are condensed. Remanence obtained in the decomposition step is washed with an aqueous solvent, preferably pure water, and the soluble and insoluble parts of the remanence are separated. By this method the halogen is removed from the waste without uncontrolled emission of halogen-containing acids to the environment.

C. or lower); separating fatty acids mixed with heavy metal and semi-metal compounds as well as the separation of organic substances (including halogenated compounds) added to heavy metals and semi-metals; and using sodium nitrite and sodium 1-naphthylamine-4-sulfonate in combination from specific solvents, thereby in the sample, adsorbing and fixating halogen substances related to air pollution, coagulation resulting from the decomposition of fatty acids and the fixation of such compounds by quicklime and graphite and the stable fixation of heavy-metal oxide and semi-metal compounds using solvents having redox action and the formation of their complex salts and compounds, the above being accomplished by a continuous processing method.
177 Method for destroying organohalogen compounds US658646 1996-06-05 US5977427A 1999-11-02 Shin Tamata; Satoru Ohashi; Toshihide Takano; Hisao Yokoyama; Toshihiro Mori
A process is provided for the destruction of organohalogen compounds, such as methyl chloride, chloroform, carbon tetrachloride, etc., by mixing the organohalogen compounds with a heated carrier gas, such as nitrogen, argon or air, and either steam or water to form a mixture; supplying the mixture to a catalyst, such as titanium oxide/tungsten oxide, to decompose the organohalogen compounds into halogens and hydrogen halides, such as chlorine, hydrochloric acid, fluorine and hydrofluoric acid; conducting the halogen and hydrogen halide contaminated gas through a bent path, created by a baffle that prevents the entry of mist or droplets into the catalyst chamber, into a cooling section where the halogen and hydrogen halide contaminated gas is sprayed with water to cool the gas to a temperature low enough to prevent the formation of dioxines. An alkaline agent, such as sodium hydroxide, can be added to the cooling water to neutralize the halides and hydrogen halides.
178 Method of decomposing CMPO US35064 1998-03-05 US5965003A 1999-10-12 Masaki Ozawa; Yasumasa Tanaka; Yoshihiro Hoshino; Hiroyuki Tanuma; Chisako Kawakami; Takamichi Kishi
CMPO is safely, reliably and rapidly decomposed under mild conditions. A CMPO-containing substance is emulsified in an electrolyte comprising an oxidation promoter (silver ion) by an emulsifier in an emulsifying tank, this electrolyte comprising the CMPO-containing substance is supplied to an anode chamber, and an electrolytic oxidation reaction is performed by passing an electric current. By emulsifying the CMPO-containing substance, the surface area of CMPO in contact with electrolyte is increased, and electrolytic decomposition is thereby promoted. As sufficient CMPO decomposition is not obtained by passing the emulsion only once through an electrolysis tank 1, a batch oxidation method is employed wherein an anolyte is recirculated by a recirculating pump 3a through the anode chamber, a constant temperature bath 7a and an emulsifying tank 6, so that electrolysis is performed with the CMPO-containing substance permanently emulsified in the electrolyte. To maintain a catholyte in a cathode chamber at the same temperature as the anolyte, the catholyte is recirculated by a recirculating pump 3b between the cathode chamber and a constant temperature bath 7b. The current supplied to an anode 4 and cathode 5 in the electrolysis tank 1 is controlled by a rectifier 8.

A method for encapsulating and immobilizing waste for disposal. Waste, preferably, biologically, chemically and radioactively hazardous, and especially electronic wastes, such as circuit boards, are placed in a crucible and heated by microwaves to a temperature in the range of approximately 300.degree. C. to 800.degree. C. to incinerate organic materials, then heated further to a temperature in the range of approximately 1100.degree. C. to 1400.degree.
