PROCESS FOR TREATMENT OF HALOGENATE VOLATILE ORGANIC COMPOUNDS USING AKALINE MOLTEN SALT

摘要

A process for treatment of halogenated volatile organic compounds using an alkaline molten salt is provided to intercept fundamentally the production of dioxins, effectively decompose the halogenated volatile organic compounds, cut off generation of secondary waste, and omit an additional post-treatment process for treating the secondary waste by reacting the halogenated volatile organic compounds with the alkaline molten salt. A process for treatment of halogenated volatile organic compounds comprises the steps of: supplying a mixed gas of the halogenated volatile organic compounds and dry air into a mixed gas supply pipe in a molten salt oxidation reactor(1) containing an alkaline molten salt(15); and contacting the mixed gas that has been supplied into the mixed gas supply pipe with the alkaline molten salt in the molten salt oxidation reactor while maintaining the mixed gas to a temperature at which the halogenated volatile organic compounds are not subjected to an oxidation reaction by the dry air. The process further comprises the step of mixing oxygen with flue gas that has been exhausted from the molten salt oxidation reactor after the reaction with the alkaline molten salt, injecting the mixed gas into a second molten salt oxidation reactor containing an alkaline molten salt to contact the mixed gas with the alkaline molten salt.
