Definitions

  • chlorine-containing compound and chlorine component in the treatable material can be converted into sodium or potassium chloride and water, and therefore hydrogen chloride forming part of a source of dioxin cannot be formed thereby realizing the unexpected results of making both emitted gas and residue harmless.
  • the thermal treatment or heating of the mixture in the thermal treatment furnace 2 is accomplished within temperature and time ranges to cover the temperature and time of generation of HCl gas and SOx gas from the treatable material, the temperature (for example, 600 °C) and time (for example, 1 hour) having been determined under a previous investigation.
  • These temperature and time are in relation to a condition (such as the size and the heating coil) of the thermal treatment furnace, the treatment amount of the treatable material, the treatment time of the thermal treatment of the treatable material, the treatment temperature of the thermal treatment of the treatable material. Therefore, the above temperature and time are required to be previously determined under a sufficient investigation and to accumulate the data to be taken for the temperature and time.
  • the chlorine removal agent sodium hydrogen carbonate
  • the chlorine removal agent was in the form of powder having an average particle size of 100 ⁇ m, in all Examples
  • the thus sealed tank was stepwise heated with a heating coil, in which heating was made at eight temperature steps of 250 °C, 300 °C, 350 °C, 400 °C, 450 °C, 500 °C, 550 °C, 600 °C.
  • the temperature at each of the eight steps was kept for 5 minutes, in which a concentration of HCl gas and a concentration of SO 2 in the tank was measured at each temperature rising time (at which the temperature was rising from one temperature step to the next temperature step) and at each temperature keeping time (at which the temperature at each temperature step was keeping).
  • the temperature rising time is indicated as "Rising time” while the temperature keeping time is indicated as "Keeping time” in Tables 1 and 2.
  • the temperature for heating the mixture of the treatable material and the chlorine removal agent may be selected according to form of facilities for accomplish the thermal treatment, time of the thermal treatment, amount of the treatable material and the like.
  • sodium hydrogen carbonate (NaHCO 3 ), sodium carbonate (Na 2 CO 3 ), sodium sesqui carbonate (Na 2 CO 3 • NaHCO 3 • 2H 2 O), natural soda (containing Na 2 CO 3 • NaHCO 3 • 2H 2 O), sodium hydroxide (NaOH), potassium hydroxide (KOH), potassium carbonate (K 2 CO 3 ), and potassium hydrogen carbonate (KHCO 3 ) can react with noxious HCl thereby to convert HCl into harmless chloride (NaCl and KCl) according to reaction formulae discussed before. It will be understood that sodium potassium carbonate and sodium carbonate hydrate can also react with noxious HCl similarly to the above.
  • chlorine-containing compound and chlorine component in the treatable material can be converted into sodium chloride (NaCl), potassium chloride (KCl), water (H 2 O) and carbon dioxide gas (CO 2 ), and therefore hydrogen chloride forming part of a source of dioxin cannot be formed thereby realizing the unexpected result of making both emitted gas and residue harmless.
  • NaOH or KOH smoothly reacts with SO2 thereby to newly form harmless sulfite (Na 2 SO 3 , K 2 SO 3 ).
  • sulfur-containing compound and sulfur component in the treatable material can be converted into sodium sulfite (Na 2 SO 3 ) in powder form, and potassium sulfite (K 2 SO 3 ) in powder form, water (H 2 O) and carbon dioxide gas (CO 2 ), and therefore SOx gas can be prevented from generation thus realizing the unexpected result of making both emitted gas and residue harmless.
  • noxious hydrogen chloride and/or sulfur oxide are converted into harmless chloride (NaCl, KCl) and/or sulfite (Na 2 SO 3 , K 2 SO 3 ), thereby making it possible to remove noxious components (hydrogen chloride and/or sulfur oxide) from the decomposition gas generated from the treatable material upon heating.
  • the decomposition gas or emitted gas from the furnace can be effectively made harmless.
  • the chloride and/or sulfite form part of the residue and can be effectively removed under a rinsing or dissolving treatment with water or the like.
  • the residual materials can be separated into respective materials which are different in characteristics by any separating means.
  • the separated respective materials are dried and massed to be usable as fuel or the like.
  • liquid (such as water) used for the above rinsing treatment hardly contains no noxious substances and therefore can be discharged as it is to a river and the sea.
