DECHLORINATION OF METAL CHLORIDES BY USING BROWN'S GAS

摘要

A method for dechlorinating metal chlorides is provided to remove chlorine components from the metal chlorides effectively, by jetting activated brown gas to waste containing metal chlorides so as to transform the chlorine components contained in the waste into hydrogen chloride. A reactor(1) receives waste containing metal chlorides. A waste containing chlorine component is transformed into hydrogen chloride by jetting activated brown gas to the waste within the reactor. When the waste is contacted with the activated brown gas, the waste is preheated to a temperature of 400-1000°C to suppress the dispersion of dust. The hydrogen chloride is removed through a condenser(3), and remaining hydrogen chloride is neutralized with a caustic sodium liquid.
