Waste Air - / Waste Gas Purification


Clean air is important for a high quality of life.

The emission of gaseous and dusty contaminations is unavoidable in almost all industrial processes. By means of ReiCat’s specific techniques, aerosols, particles, smells and hydrocarbons can be removed out of the waste air / waste gas or exhaust airstream.

Gaseous organic emissions which are also called VOC (Volatile Organic Compounds), take centre stage of the legal regulation to air pollution prevention.

The integration of the European VOC guideline (1999/13EG) into national legislation forces all companies to stick to this standard for the limitation of emissions.

ReiCat offers customized waste gas purification units achieving highest purity with minimal energy input.

  • Treatment of varying waste air amounts and compounds
  • High purification effect of up to 99 %
  • Low investment
  • Low energy consumption
  • High lifetimes

Catalytic Incineration


Waste air contaminated with burnable organic toxics (VOC) can be cleaned by oxidation safely and nearly residue-free. Here the contaminated air is heated up, the organic components mostly oxidise to water and CO2 / carbon dioxide. This process is called thermal incineration with a temperature range of at least 750-1000 °C.

In contrast at the waste air treatment via catalytic incineration the reaction temperature for total combustion will be reduced to 250-400 °C.

The consumption of primary energy dramatically reduces in comparison to a thermal incineration. The thermal load of a catalytic incineration is considerably lower, which positively results in a long life time of all applied materials.

ReiCat selects the suitable catalyst for each process and chooses specific formula for the production of catalysts. If necessary, this also allows the treatment of chlorine containing waste gases at reduced temperatures, whereby creation of dioxins can be avoided.

The assembly of the catalyst bed is made of modules consisting of inserts. All catalytic incinerations can be equipped with (primary) heat exchanger, which allow an auto thermal operation of the unit, if sufficient concentration of hydrocarbons is guaranteed. In this case, the energy supply will be reduced to a minimum.

Via an additional (secondary) heat exchanger the remaining energy of the waste gas can be used.

Generative Incineration


Use your exhaust gas as fuel!

Permanently searching for improved environment friendly treatments of waste gases, our engineering team developed the generative incineration, combining many advantages.

During this process the waste gases, containing a preferably high content of burnable compounds, are mixed with small amounts of natural gas, feeding a specially designed burner. This means, that the total calorific value of waste gas is used for heating and only a minimum of primary energy is needed.

The subsequent catalytic incineration provides a complete and durable conversion of the remaining impurities.

  • Oxygen-free exhaust air with high shores of organic pollutions such as from vacuum carburizing processes.


  • Very compact design due to low volume flow, as feed of air to waste gas is not necessary. Air is only fed at the burner.
  • Availability within few minutes, applicable for short and long operation times.
  • Independent from concentration of hydrocarbons in the waste gas
  • Less requirements to explosion control
  • Little costs of purchase, little maintenance costs, less energy consumption
  • Cost advantage to catalytic incineration: - 50 %
