For over 20 year we have been leading the sector of industrial pollution control, offering a comprehensive range of technologies for air purification to a wide range of industries, with special attention to the problems of gaseous emissions containing Volatile Organic Compounds (VOC).


Thermal oxidation converts pollutants into secondary products with low environmental impact as a result of the following reaction:
V.O.C + O2 + Activation energy = CO2 + H2O + heat

The reaction requires specific temperatures, turbulence and retention time in the combustion chamber; the energy necessary for the reaction can be recovered as heat through special thermal recovery systems (recuperative thermal oxidation).



Regenerative thermal oxidation allows you to destroy the VOC’s with a high degree of thermal efficiency by using ceramic media to accumulate and release heat rapidly. The plant usually comprises three canisters containing ceramic media but, according to the airflow to treat and the required abatement efficiency, we can propose solutions with 2 canisters, 2 canisters+buffer tank or even 5 or more canisters.


Catalytic oxidation of VOC’s at reduced temperature is achieved by means of a catalyst, which considerably reduces the required energy for the activation of the reaction.
The plant can be equipped with a conventional shell and tube type heat exchanger (recuperative catalytic oxidation), or, with beds of ceramic media, (regenerative catalytic oxidation), thus to optimize the energy consumptions.



Solvent recovery occurs as the pollutant contained in the gaseous emission is transferred (adsorption) to an adsorbing material such as activated carbon, and then removed from it by means of a hot fluid (steam or nitrogen, according to the water solubility of the pollutant).

Plants are equipped with auxiliary systems for:

the treatment of condensate;
the reduction of steam consumption (economizer);
the dehydration and distillation of recovered solvents.


Concentration plants were introduced to achieve reduced airflows with high VOC concentrations from high inlet air flows with low VOC concentration. The concentrated exhaust stream can then be treated in a much smaller abatement plant.

Concentration occurs by adsorbing the contaminant in the gas stream on special materials (zeolite or activated carbon) and then removing it with hot air at a much lower flow rate in order to achieve a higher VOC concentration going to the final treatment plant. By doing this, it is possible to reduce the size and operating costs of the final plant or, to further reduce the outlet emissions of existing plants in order to comply with more restrictive limits.



Wet treatment allows the removal of the pollutants contained in atmospheric emissions by absorbing them in a liquid. This will only happen at suitable contact conditions. It is often necessary to dose reactors in order to make these conditions more favorable to convert pollutants into more transferable products.


Incineration is the thermal destruction of pollutants, both in solid and liquid form, by converting them into secondary products that have a reduced impact on the environment.
The process must occur at the appropriate temperature and contact conditions and in conjunction with treatment of the combustion gases.
