The Puratech company is a supplier of air filters (mechanical, carbon) for process equipment in the industry and individual ventilation devices.

We will solve your problem of odor, corrosion, and indoor air quality with filtration from industrial processes.

We conduct an air aggressiveness test and perform a comprehensive object exchange of filters together with cleaning and de-molding devices.

Gas phase filtration:

Our gas phase filtration solutions are designed to protect sensitive components and systems from the environment.

Some of the industries where gas filtration is needed to avoid odor, corrosion, and indoor air quality issues are:

* Data centers,
* IT / server rooms,
* Oil and oil refineries,
* Food processing plants,
* Paper industry,
* Sewage treatment plants and sewage treatment plants,
* Museums and libraries. 

Biogas and biomethane purification

What is biogas?

Industrially generated biogas is a source of energy produced from different types of organic matter through anaerobic fermentation. The resulting gas consists of methane (CH₄), carbon dioxide (CO₂), and traces of other gases including hydrogen sulfide (H₂S).

Biogas is used as a renewable fuel alternative to the current dependence on fossil fuels such as gas natural, oil and coal.

Why is it important to filter the gases in a biogas plant?

Because the gases resulting from anaerobic fermentation contain trace amounts of pollutant gases, it is necessary to filter these elements and purify the resulting gas.
The removal of hydrogen sulfide gas is crucial for reasons of health, safety, environment and corrosion of equipment such as gas engines, boilers and pipelines. Desulfurization is also necessary when upgrading biogas to inject quality natural gas into the grid. 
Siloxane gases are mainly found in biogas sources originating from a landfill. Removal of siloxanes is essential for the proper functioning and longevity of the equipment present.

Desulphurization:

The unique filtration media designed to desulphurize biogas facilities, allows the reduction and control of gases resulting from the anaerobic digestion of organic matter.

The removal of sulfur gas is crucial for health, safety, environmental and corrosion reasons from equipment such as gas engines, boilers and pipelines. Desulphurization is also necessary when upgrading biogas to inject quality natural gas into the pipeline.

BION has a wide range of filter media and solutions designed on purpose to turn biogas into a clean, renewable source of energy.

Siloxanes:

One of the most efficient technologies for the removal of siloxanes in biogas plants is BION’s range of virgin carbons.

Siloxane gases are mainly found in biogas sources originated in landfills. The removal of siloxanes is essential for the proper functioning and longevity of the equipment present. Siloxanes are deposited in the form of silicon dioxide (SiO2) in the cylinder head, which can damage the valve seat and cause erosion of the metal parts of the equipment.

 

In our solutions, we include the proper BION media needed for each project.

Since 2023, we have become the exclusive distributor of BION molecular filtration in Poland.

BION (www.bioconservacion.com) is one of the leading European manufacturers of molecular media for air filtration and gas purification in the industry, since 1996.  

BION develops, innovates, and manufactures a wide range of media that allows us to offer the most complete and accurate solution in the market.
