Abstract:
In this paper, an AC plasma arc reactorwithworkinggasofhydrogen is applied to destruct chemicalagents. The temperature attains 6000℃ in the arc area and over 2000℃ in the other space of the crucible. The Arsenic (As) contained chemical agent -Adams (DM) used in the experiment, was added into the plasmareactorwith the additives: Fe, CaO, and SiO_2, etc. Pyrolysis and destructionofchemicalagents occurs very quickly in the high-temperature reactor. Gaseous hydrogen was injected into the reactor to form a reductive environment, to reduce the formation of As_2O_3 etc. In the bottom of the crucible, the solid residues of toxicant and additives were melted and formed as vitrified slag. The off-gas was treated by a wet scrubber. The amounts of arsenic distributed in the off-gas, vitrified slag, waste water and solids (soot) were measured. The result shows DM is completely destructed in the plasmareactor. The Arsenic content in the off-gas, vitrified slag, waste water and soot are 0.052 mg/l, 3.0%, 10.44 mg/l, and 5.1% respectively, which will be disposed as the pollutant matters. The results show that the plasma technology is an environmentally friendly technology to destruct chemicals.
