H₂S, CO₂ and H₂O removal
Gas purification is critical to the performance of modern biogas upgrading facilities. Poor contaminant removal can lead to off-spec compressed biogas (CBG) and biomethane, reduced methane recovery, equipment damage, elevated operating costs and unplanned shutdowns. Water vapor (H₂O), hydrogen sulfide (H₂S) and carbon dioxide (CO₂) must be effectively removed to produce high-purity biomethane suitable for compression, transport and end-use applications.

Protect: Hydrogen sulfide removal
UOP GB-260
Hydrogen sulfide is one of the most aggressive contaminants in biogas streams. GB-260 is a high-capacity sulfur removal adsorbent designed to help protect equipment, reduce corrosion risk and support biomethane quality specifications. Its extended sulfur pickup capacity can support longer operating periods between changeouts while enabling straightforward retrofit into existing systems.
- Help safeguard PSA/VPSA systems, downstream piping and critical equipment
- Support CBG quality and pipeline spec compliance
- Promote reduced operating costs through enhanced process protection

Stabilize: Moisture removal
Biosiv™ WG series
The Biosiv WG portfolio includes activated alumina and molecular sieve technologies engineered for applications ranging from bulk water removal to ultra-low moisture control. By efficiently removing water vapor, Biosiv WG adsorbents help protect compressors and purification systems, extend downstream equipment life, improve reliability and reduce maintenance requirements.
- Biosiv WG-100: An activated alumina adsorbent designed for efficient bulk moisture removal.
- Biosiv WG-300: A high selectivity molecular sieve adsorbent, engineered for delivering low moisture levels in the end product.
- Biosiv WG-400: A molecular sieve adsorbent offering a balance of drying performance and operational reliability.
-
Enrich: Carbone dioxide removal
Biosiv™ CG series
Carbon dioxide is the primary impurity in raw biogas, typically comprising 35%–45% of its composition. This high concentration significantly lowers the fuel’s calorific value, thereby reducing its overall energy efficiency and limiting its usage. Biosiv CG molecular sieve adsorbents are specifically engineered for efficient CO₂ separation, helping increase methane purity, improve calorific value and optimize biomethane recovery.
- Biosiv CG-100: Versatile adsorbent solution with high CO2 adsorption capacity, low attrition and rapid adsorption kinetics.
- Biosiv CG-200: Premium adsorbent solution with high CO₂ adsorption capacity, excellent selectivity, low attrition and robust mechanical strength.
