Definitions

  • the invention relates to a method according to the preamble of the first Claim and an apparatus for performing the method.
  • the invention can be used wherever halogen-loaded carbon-containing residues and waste materials to produce a carbon monoxide and hydrogen containing gas with simultaneous extraction of halogen-containing materials to be recycled.
  • halogen-containing carbon-containing residues and waste materials are with organic or inorganic halogen compounds Hydrocarbon oils, chlorine-containing plastics, halogen salt infiltrated carbonaceous materials, loaded with halogen compounds Sewage sludge, contaminated hydrohalic acids and contaminated Understand halogenated hydrocarbons or mixtures thereof.
  • PCDD polychlorinated dibenzodioxins
  • PCDF Dibenzofurans
  • halogen-contaminated residues and waste materials has been known for many years in the technology of gas generation.
  • DE 41 09 231 C2 describes a process for recycling halogen-containing carbon-containing waste materials, in which these are reacted together with oxygen in the flame of an entrained-flow gasifier to form a gas that is rich in CO and H 2 and contains hydrogen halide.
  • the entrained-flow gasifier consists of a reaction chamber which is followed by a quenching of the hot gasification gas (J. Carl, P. Fritz, Noell conversion process, EF-Verlag für Energy undmaschinetechnik GmbH 1996). A pressure of 26 bar prevails in the reaction space.
  • the temperature conditions in the reaction chamber necessary for the process are controlled by regulating the ratio of oxygen to residual and waste material.
  • a temperature of 1350 ° C. to 1400 ° C. at the outlet of the reaction space is set. Due to the limited rate of conversion of the residual and waste materials and the incomplete mixing of the reactants due to the high viscosity of the gas phase, the gasification process in this single-chamber reactor does not go completely against the thermodynamic equilibrium. Soot formed during the gasification process and residues of higher molecular weight organic and halogen-organic compounds require complex processing of the gasification gas and impair the quality and usability of the halogen-containing valuable substances such as hydrochloric acid, which is obtained by absorbing hydrogen chloride in water in quenching and subsequent washing processes. Furthermore, the soot and residues formed in the gasification process lead to corrosion of the system.
  • the invention has for its object the possibility of gasification according to the principle of partial oxidation in the entrained flow for recycling halogen-containing residues and waste materials and a versatile usable gas containing carbon monoxide and hydrogen and high quality materials such as hydrohalic acids or Halogen salts, so that from the halogen content of Feed material resulting environmental pollution for atmosphere, water and soil avoided by toxic substances and corrosion in the corresponding plant remain largely restricted.
  • the process according to the invention assumes that halogen-containing and carbon-containing residues and waste materials in a flowable state and a free oxygen-containing gasifying agent in the form of a Multi-stage flame reaction at an increased pressure to one raw gas containing carbon monoxide, hydrogen and hydrogen halide be implemented.
  • this is carried out at a temperature of at least 1100 ° C. a first reaction chamber generated raw gas, the unreacted Has components supplied to further reaction chambers in which due to the flow guidance, an intensive mixing takes place, which leads to leads to further sales of the components not yet gasified.
  • a first reaction chamber generated raw gas the unreacted Has components supplied to further reaction chambers in which due to the flow guidance, an intensive mixing takes place, which leads to leads to further sales of the components not yet gasified.
  • Gasifying agent containing oxygen can be supplied.
  • the upper reaction chamber 2 is provided with a burner 1.
  • the halogen-containing residual or waste material and technical oxygen are fed to this burner 1 via delivery lines. Both components react with one another to form a flame within the reaction space 2, producing CO, H 2 and hydrogen halide gas.
  • a pressure> 2 bar prevails in reaction chamber 2.
  • the temperatures in the reaction chamber necessary for the process are controlled by regulating the ratio of oxygen to feed material.
  • a temperature at the outlet of the reaction chamber 2 is set to be greater than 1100 ° C.
  • the hot gasification gas is passed into the second and third reactor spaces 2, where the rest of the components not yet gasified are reacted by intensive mixing.
  • a free oxygen-containing gasification agent can additionally be supplied in the second and third reactor chamber 2, shown here as an example, via supply channels 6.
  • the gas containing CO, H 2 and hydrogen halide leaves the last reaction chamber 2 via the outlet device 5 and arrives in the subsequent cooling, washing and cleaning systems.
  • Fig. 2 shows three reactor rooms 3, which are not in one Pressure vessel are housed, but in three individual pressure vessels 3, that are connected. The process of gasification takes place in the way listed in Example 1.
  • reaction spaces 2 in a single reactor.
  • the Reaction spaces 2 are here within a uniform Pressure vessel separated by divided base plates 4.
  • the feeding of the Gasification media and the discharge 5 of the gasification products 5 take place as described in Fig. 1.
