Understanding Biomethane and its Benefits
Biomethane is a combustible gas produced from biogas, through a process called "biogas upgrading". This process removes impurities from the biogas, allowing it to be reused as a form of renewable energy - also providing economic advantages, such as lowering energy costs and improving financial performance.
Our Innovative Biomethane Solutions
From waste to energy, we are present at every step of the biomethane value chain.
Using a circular economy model, we can process your waste products (such as food, agriculture, and sewage sludge) into biogas, which is then upgraded and other gases like CO2 are extracted, resulting in the production of biomethane - a renewable fuel.
The obtained biomethane can be adapted according to the specific needs of its utilisation, using various biomethane valuation techniques such as liquefaction.
We can also use our CO₂ recovery technology to reuse the discarded CO₂ from the upgrading process, to be upcycled or sold for other applications.
Upgrading
Vacuum Pressure Swing Adsorption
Using differential adsorption, this separation method efficiently separates methane (CH4) and carbon dioxide (CO₂) on an adsorbent material, offering low energy consumption. It also partially separates nitrogen (N₂) and minimises methane losses while handling biogas with high O₂ and N₂ concentrations.
Membranes
Based on the differential diffusion behavior of chemicals through a specific membrane, this method offers simplicity, low energy consumption, and suitability for both small and large-scale productions. It ensures minimal methane losses.
Chemical absortion
Based on differential solubility in a washing liquid, this method separates biogas components. Those more soluble in amine or alkaline salt solutions (e.g., KOH) are absorbed and removed from the gas stream. Chemical absorption with amines is suitable for high flow rates, ensuring minimal methane losses.
Pressurized Water Scrubbing (PWS)
Based on differential solubility in water at low pressures and temperatures, this method separates compounds from the biogas. The most soluble components in the wash water are removed from the gas stream. The process regenerates the water by extracting air, which ensures low maintenance costs.
Thanks to our expertise in gas separation, our solutions for liquefying biomethane to bioLNG provide you with low carbon fuels with easy transport and storage.
In order to do so, there are different types of liquefaction: LIN and mechanical liquefaction.
Biomethane can also be compressed and used as a low carbon vehicle fuel (CNG) or be injected into the natural gas grid, providing renewable energy.
