Conversion of toxic halogenated organic cpds. from incinerator filter dust - comprises adding glycol to alkaline e.g. filter dust or absorption material and adding water-glass to agglomerate

摘要

Converting halogenated, cyclic hydrocarbons into inorganic halide cpds. comprises treating alkaline material, e.g., filter dust from incinerators or absorbers used for air purificn. in waste incinerators with glycol to dissolve organically bound halogens and convert them into inorganic cpds.. Waterglass is then added to the treated material to improve agglomeration and simultaneously increase the rate of reaction. USE - Dust and/or absorption media can be recycled or safely disposed of, due to the removal of toxic cpds. such as furans and dioxin
