The pre-treatments and therefore the pre-scrubbers are used to preserve the thermal oxidizer both from a mechanical and process point of view, reducing the concentration of particular types of pollutants such as:

  • organic silicone compounds
  • inorganic acids
  • inorganic bases
  • aerosol
  • dust
  • painting overspray
  • oily mist and/or condensate droplets

In this condition, appropriate systems are installed, such as cyclones, bag or cartridge filters, Venturi and tower scrubbers, filtering panels, activated carbon adsorbers, various types of demisters or even more complex systems to evaluate for each case.

For post-treatments and therefore for the post-scrubbers, rapid cooling systems are typically used such as quenchers followed by tower scrubbers possibly with Venturi-pre-abatement.

At times DeNOx SCR or SNCR systems could need to be used to reduce NOx consisting of particular organic compounds such as amines.

The various post-abatement systems are applied in the presence of incoming pollutants such as:

  • Halogenated VOC
  • Sulphurised VOC
  • Nitrogenous VOC
  • Silanes or siloxanes

Features and advantages

  • Electrical switchgear with PLC and remote assistance
  • High purification efficiency >99%
  • Easy to manage and use.
  • Reduced maintenance

Operating principle

For VOC pollutants containing silicon, nitrogen, sulphur and halogenates together along with other non-organic pollutants such as acids, bases or simply dust, the thermal oxidizers can be supplied with particular equipment to be installed before and after the oxidizer to be able to treat the largest range of pollutants possible.
