VALOCARB^© technologies do not only work with CO₂.

They also capture pollutants such as SO₂, NO₂, H₂S, and many other harmful molecules.

The properties of these technologies make the most complex gases the best captured, making it possible to process a wide range of these problem gases.

These technologies apply in particular to the purification of biogas, usually composed of 50 to 70% methane (CH₄), 25 to 40% CO₂ and problematic minority compounds (H₂S, siloxanes).

This purification constitutes an estimated market in Europe at several hundred million euro per year.

LPurification solutions are subject to the costs and variability of biogas composition.

Different solutions now treat H₂S and CO₂, almost always separately.

Siloxanes, which are difficult to capture, remain a thorn in the feet of farmers, since no technology has really established itself on the market today.

All involve the implementation of cumbersome systems and have high investment and operating costs (energy, water, reprocessing of active coal…).

The VALOCARB^© solution for biogas consists of a combined purification (CO₂, H₂S and siloxanes) with the possibility of CO₂ valorization, at the operator’s request.

It can meet three main needs:

• upgrading to standards (CO₂ and H₂S purification) for the injection of biomethane into the natural gas network.
• upgrading to standards (CO₂ and H₂S purification) for the use of biomethane in liquefied form (Natural Gas CNG Vehicles).
• desulphurization before cogeneration (H₂S and siloxanes).
