Exhaust gas treatment and air pollution control

To ensure that industrial processes which emit pollutants, such as incineration plants, are carried out in an environmentally friendly manner, innovative technologies and the adequate treatment of exhaust gases are indispensable. In this context, it is especially important to reduce pollutant emissions that have a negative impact on the quality of the air and directly endanger human health. In particular, these include fine organic and inorganic dusts, carbon monoxide, polycyclic aromatic hydrocarbons, volatile organic compounds, nitrogen oxides (NOx), sulfur dioxide, hydrogen chloride, hydrogen fluoride and heavy metals.

These pollutants can be treated in different ways. Our core expertise lies in integrated process-specific technologies, as well as downstream exhaust gas treatment techniques and secondary measures. We have also developed patents with the corresponding industrial property rights.

Integrated exhaust gas treatment plants include the selective non-catalytic reduction of nitrogen oxides (SNCR process), as well as the cyclone burner technology and the use of special built-in components. These are mainly utilized in small firing systems to separate dust emissions, as well as to optimally oxidize combustible exhaust gas constituents and pollutants.

We offer the following processes for treating particulate and gaseous pollutant emissions in downstream exhaust gas:

Process for the treatment/separation of particulate pollutants:

• Mass force separators (cyclones, gravity separators, inertial force separators)
• Wet separator
• Filtering separators (cleaning filters, storage filters, bulk layer filters)
• Electrostatic precipitators

Process for the treatment of gaseous and vaporous pollutants:

• Condensation process
• Adsorption process
• Absorption process (exhaust gas scrubber)
• Oxidation processes (thermal post-treatment, catalytic post-treatment, special processes)
• Reduction process (SCR process: selective catalytic reduction)
• Other special exhaust gas treatment processes, such as bio-filters, bio-scrubbers, etc.

However, our services are not just limited to developing and researching into exhaust gas treatment systems. We also carry out approval tests according to the preliminary DIBt test program (German institute for building technology) and DIN SPEC 33999:2014-12.

In addition, we determine the effectiveness of exhaust gas treatment systems and other air pollution control measures in residential areas by assessing the quality of the air in accordance with the information stated in the 39th German Federal Immission Control Act (BImSchV).
