Air quality system

Expertise and solutions in electricity, instrumentation, automation and control systems

The air pollution is mainly due of the industrial processes. Most pollutants havedeleterious effects on humans and the environment. It’s at the centre of Boccardconcern, limiting and controlling Dust, NOx and Acid emissions to meetEnvironmental limits. Health effect is also our responsibility!

As air pollutant emissions became more and more a legal limited factor when it comes to operatesplant, be the partner able to address causes and solutions in this regards is key for plant Operator.

As a EPC company, Boccard is active in all main Industries sector such as Waste to Energy, Refinery or Steel. Having in house the capabilities to design up to operate the exhaust flue gas isan asset comparing other actors in this field.

Our offer

Commited experts and solutions for greater flexibility

We are supporting you to devlopp, size , design, build and maintain your flue gas treatment accros all our Air Quality System products line:


Inhalable particles, those smaller than 10 μm, often get trapped in the nose, mouth and upper respiratory tract, thus can be associated with respiratory disorders such as asthma, tracheitis, pneumonia, allergic rhinitis and silicosis.

The choice between available technologies are often the proper balance between requirement, physico-chemical characteristics of industrial processes, CAPEX and OPEX limitation.

To remove particulates from exhausted gases, supplied technologies are:

  • Multicyclones (MCC)
  • Electrostatic Precipitators (ESP)
  • Fabric Filters (FF)
  • Hybrid Collectors (HC)


Thermal nitrogen oxides are formed at high temperatures from molecular atmospheric nitrogen and the oxygen in the combustion air.

NOx is a generic term for the nitrogen oxides that are most important for air pollution, namely nitrogen oxide (NO) and nitrogen dioxide (NO2).

These gases contribute to the formation of smog and acid rain and affect tropospheric ozone.

To remove NOx from exhausted gases, Amonia or derivated are essential. The supplied technologies are:

  • Selective Catalytic Reduction (SCR)
  • Selective Non Catalytic Reduction (SNCR)


Acid and others component such as SOx, HCl, HF, Dioxine,Furane and Heavy Metals (Hg) are armful for environment and life. It has always been in significant quantities in all major fuels used in our industries and usually come together in various proportions.

echnologies has been optimized continuously in close collaboration with chemical sorbent producers all around the globe. Preferred ones are Sodium Bicarbonate, Activated Carbon, lime, caustic Soda and several others.

The equipment are often complex and would be better named as a System that allow various chemical reaction between Sorbent and Pollutants.

Available and proven technologies, cost effective, and suitable for most of industrial cases are:

  • Dry Sorbent Injection (DSI)
  • Semi-Dry System
  • Wet scrubbing
