How Pressure Swing Adsorption Delivers Pipeline-Quality Biomethane The Need for Ultra-Pure Biomethane When upgrading biogas, some projects aim for the highest possible methane purity — especially when the end use involves sensitive equipment, export contracts, or strict grid specifications. Many upgrading plants use PSA (Pressure Swing Adsorption) technology to produce high-purity biomethane. How PSA Works […]

From Biogas to Biomethane — Why Upgrading Matters Biogas is a renewable energy source created from organic waste through anaerobic digestion. But in its raw form, biogas contains impurities like carbon dioxide (CO₂), hydrogen sulfide (H₂S), and moisture. For it to become high-value biomethane — suitable for grid injection, transport, or use as compressed natural […]
