The decomposition of halogenated hydrocarbons by MSO 

Popis výsledku v původním jazyce

Concentration limits are set in wastewater, waste, and air for the content of many substances including halogenated hydrocarbons. The increase in the industrial use of these substances leads to a high burden on the environment. For this reason, these substances must be effectively disposed of. The combustion of halogenated organic substances requires an effective flue gas cleaning system to prevent often more dangerous decomposition residues from escaping into the air. An alternative to conventional methods of disposing of halogenated hydrocarbons is the MSO (Molten Salt Oxidation) technology, in which the substances in question are dosed together with an oxidizer (air) below the surface of the alkali carbonate molten salt. At high temperatures (approx. 1273 K) is the organic carbon oxidized in ideal conditions to carbon dioxide. The product of halogen removal is an alkali halide. The aim of the work was to test the possibility of the tetrachlorethylene decomposition in the two-reactor laboratory apparatus. During the process the emerging decomposition products of chlorinated hydrocarbons were monitored. A high content of carbon monoxide was detected in the off gas during the decomposition. The chlorine capture efficiency was around 70% depending on the dosage of the input reagents. The obtained results confirmed the real possibility for disposal of hazardous halogenated hydrocarbons by the MSO process. Further work will be focused on monitoring the optimal control of the entire process with the possibility of detecting any other byproducts. At the same time, new construction materials that will withstand the high corrosive environment will be tested.
