Industrial Air Pollution Control and Odour Treatment Case Studies

Real plants for real operating conditions. Real engineering decisions. No catalogue solutions.
Industrial air pollution control systems designed for real process emissions.

Industrial air pollution control case studies showing real systems designed for complex industrial emissions and demanding operating conditions. These industrial air pollution control case studies present real industrial air pollution control systems designed for demanding operating conditions and complex industrial emissions.
Typical technologies used in these projects include Venturi scrubbers, packed column wet scrubbers and multistage chemical scrubbing systems designed for industrial gas absorption and odour removal.
These industrial air pollution control case studies illustrate how engineering decisions must be driven by real operating conditions rather than simplified catalogue configurations.
Each project reflects the need to adapt the air treatment system to the specific behaviour of the industrial process generating the emission.

Industrial Sectors Covered in These Projects

The air pollution control systems presented in these case studies have been designed for different industrial sectors where odour and gas emissions represent a critical environmental issue.

Typical applications reported in the following industrial air pollution control case studies include:

Each project required a specific engineering approach based on the real characteristics of the air emission source.

Typical Industrial Air Emissions Treated in These Case Studies

Industrial air emissions vary significantly depending on the production process generating them. In many industrial sectors, air streams contain complex mixtures of odorous compounds, volatile organic compounds (VOC), sulphur compounds and process aerosols.

For example, pet food production plants typically generate emissions during extrusion, drying, coating and cooling stages. These air streams often contain fatty acids, amines and organic vapours that require dedicated odour control systems.

In wastewater treatment plants and sludge drying installations, emissions may contain ammonia, hydrogen sulphide and other sulphur compounds generated by biological degradation processes. These compounds are responsible for strong odour impact and must be removed through properly designed air pollution control systems.



In animal by-products processing plants, air emissions are characterised by highly variable pollutant concentrations and by the presence of condensable organic compounds. These emissions require robust air treatment systems capable of handling fluctuating operating conditions.

Industrial air pollution control systems used in these case studies therefore combine different gas treatment technologies such as Venturi scrubbers, packed column wet scrubbers and multistage chemical scrubbing systems designed for reliable pollutant removal.

Air Pollution Control Technologies Used

The industrial air treatment systems presented in these case studies combine several gas treatment technologies to ensure stable operation and emission compliance.
Depending on the characteristics of the emission stream, the systems may include:

These technologies are selected and dimensioned based on the chemical composition, temperature, humidity and variability of the industrial emission.

Real Engineering Solutions for Complex Industrial Emissions

Industrial air emissions rarely follow ideal laboratory conditions. Flow rate fluctuations, aerosol formation, condensable compounds and variable pollutant concentrations require flexible and robust air pollution control systems.

The case studies presented here illustrate how engineering decisions are driven by real operating conditions, not by catalogue configurations or simplified design assumptions.

Each project reflects the need to adapt the air treatment system to the specific behaviour of the industrial process generating the emission.

Industrial air pollution control case studies demonstrate how emission treatment systems must be designed around real operating conditions. Air flow variability, pollutant concentration, aerosol formation and temperature fluctuations all influence the performance of odour control systems and wet scrubbers used in industrial applications.

Each project presented here reflects the need to adapt the air treatment system to the specific characteristics of the industrial process generating the emission.
