VOC/Odor Treatment Catalyst

voc 08Catalytic combustion method is well known as one of the means of exhaust gas treatment for VOC which may cause air pollution, odor problem. It is oxidation reaction between flammable gases such as VOC and air. In case the gases are hydrocarbons or organic compounds containing oxygen in the structure, they are converted into non-harmful CO2 and H2O by oxidation reaction and it generates heat of reaction for heat recovery.

Application and Performance

Please advise us of the following items, if you have an inquiry for exhaust gas treatment. N-U can also introduce engineering companies who can design and manufacture a catalyst combustion system, if required.

  • Source of exhaust gas and its system configuration
  • Exhaust gas flow rate
  • Exhaust gas Temperature
  • Exhaust gas pressure
  • Exhaust gas composition/concentration
  • Existence of solids such as dust, and possibility of catalyst poisons
  • Required performance at outlet
  • Utility Availability
