Waste liquid incineration / Submerged combustion system

Treatment of waste liquid containing alkali metal compound and high COD substance


  • Operation of waste liquid containing alkali metals without clogging
  • Complete decomposition of organic matter and high COD substance
  • No producing dioxins by quenching system
  • Simultaneous treatment of waste liquid oil and gas
  • Non-catalytic NOx decomposition

Application examples

  • Waste liquid/gas from manufacturing process of chemicals, agrochemicals, organic pigment e.g. acrylonitrile, aclylic acid ester, caprolactam, CVL...
  • Waste liquid from industrial waste disposal facility
  • Waste liquid from desulfurization process such as STRETFORD, TAKAHAX and FUMAX.
