Study of thermal detoxification of gas cleaning solid residues from garbage disposal plant filters

  • Published:
Chemical and Petroleum Engineering Aims and scope

Detoxification of ash waste formed in garbage disposal plants by a new thermal method is considered. An experimental computational and theoretical study is made of the desorption of dioxins from the surface of ash by a new heat treatment method for processing garbage disposal plant gas cleaning solid residues in an inert atmosphere in order to analyze processes that occur during heating of gas cleaning solid residues. It is demonstrated by calculation and theoretically that dioxin desorption occurs at temperatures 2-3 times lower than the waste melting temperature. It is established by experiment that in the range 300-900°C in an argon atmosphere, and at a pressure exceeding the dioxin saturation pressure, dioxin degradation occurs in gas cleaning particles from garbage disposal plants with formation of stable natural non-toxic chlorine-containing minerals.
