FROM BIOGAS TO BIOMETHANE
– RENEWABLE NATURAL GAS (RNG)

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) units are specifically 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%.

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%.

HYBRID TECHNOLOGY

The hybrid system benefits from positive aspects of both PSA and Membrane systems. As an example, the membrane system is only preferred over a PSA system when the operating pressure is higher than 250 psig; however, the hybrid system is able to operate in wide ranges of pressure (100-400 psig).
