Xebec Biogas Solutions From Biogas to Biomethane Biogas is a mixture of CH4 , CO2 , and other trace gases. It is produced from anaerobic digestion of food waste, animal manure, landfills, and sewage. After pre-treatment (H2S, VOCs, Siloxanes, Ammonia and H2O) and purification steps, biogas is upgraded to biomethane, a renewable substitute for natural gas.

Fast Cycle PSA Technology Xebec’s compact, Fast Cycle Pressure Swing Adsorption (PSA) is designed to upgrade biogas feed streams containing CO2, H2O, H2S, and high amounts of N2 and O2 (total molar content of 0% to 30%). Xebec’s proprietary PSA technology is highly efficient, with proven recovery rates up to 96%. Our Point of Difference High N2 and O2 removal rates • The adsorbents used in Xebec’s PSA system have high kinetic selectivity toward N2 and O2 • Apart from high rates of CO2 removal, up to 95% of the inlet N2 and O2 can be removed from CH4 in the adsorption process Adsorption Process...

Membrane Technology Xebec’s high-performance polymer membranes are suitable for treating biogas streams which mainly contain CH4 and CO2. Xebec membranes selectively separate CH4 from CO2 and other trace gases and upgrade biogas to pure biomethane with recoveries as high as 99.8%. Hollow Fiber Membrane Best in class performance • Recovery rates up to 99.8% CH4 purity up to 99% ease of operation No moving parts • High turndown rates • No chemicals required • Xebec’s membrane system is modular and easily scalable • Green energy • Due to the very low CH4 concentration in the exhaust stream, no post-treatment...
