Innovative ozone technology for industrial emissions control
Ozone-based flue gas treatment solutions are increasingly used by industrial facilities and power plants to reduce atmospheric emissions and meet stringent environmental regulations. Thanks to its strong oxidizing properties, ozone enables efficient treatment of key pollutants such as nitrogen oxides (NOx), volatile organic compounds (VOCs), and trace contaminants in combustion exhaust gases.
Industries seeking flexible, high-performance, and future-proof emission control technologies are turning to ozone as a powerful tool for cleaner operations.
What is ozone-based flue gas treatment?
Ozone-based flue gas treatment is an advanced oxidation process in which ozone (O₃) is generated on-site and injected into flue gases downstream of combustion units. Ozone reacts rapidly with pollutants, converting them into more stable, soluble, or easily removable compounds.
Objectives of ozone gas treatment systems
Ozone solutions are designed to:
- enhance the removal of nitrogen oxides (NOx),
- improve overall flue gas cleaning efficiency,
- complement existing emission control systems,
- reduce environmental and health impacts,
- support compliance with current and future regulations.
Key pollutants addressed by ozone solutions
Nitrogen Oxides (NOx) reduction and denitrification
NOx emissions are a major concern for power plants and industrial combustion processes. Ozone efficiently oxidizes nitric oxide (NO) into nitrogen dioxide (NO₂) and higher oxides, which are easier to remove in wet scrubbers or flue gas desulfurization units. This makes ozone a highly effective solution for flue gas denitrification, either as a standalone process or in combination with conventional technologies.
Volatile Organic Compounds (VOCs)
Ozone reacts with VOCs, breaking them down into less harmful compounds. This contributes to improved air quality and reduced formation of secondary pollutants such as ground-level ozone.
Mercury and Trace Pollutants
In certain applications, ozone oxidizes elemental mercury and other trace contaminants, enhancing their capture in downstream treatment systems.
Ozone-based flue gas treatment technologies
On-site ozone generation
Ozone is produced on demand using electrical discharge systems, eliminating the need for chemical storage and transport. This ensures operational safety and supply reliability.
Ozone injection and mixing systems
Precise ozone injection and optimized mixing ensure effective contact between ozone and flue gases, maximizing pollutant oxidation while minimizing ozone consumption.
Integration with existing gas cleaning systems
Ozone solutions are easily integrated with:
- wet scrubbers,
- flue gas desulfurization (FGD) systems,
- particulate control units,
- hybrid multi-pollutant treatment trains.
Industrial applications of ozone flue gas treatment
Ozone-based solutions are widely applied in:
- coal-fired and gas-fired power plants,
- combined cycle power plants,
- waste-to-energy and incineration facilities,
- cement and metallurgical industries,
- chemical and petrochemical plants.
These solutions are particularly well suited for retrofitting existing installations with minimal disruption.
