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).
