Ivys Adsorption’s rotary valve and highly efficient proprietary adsorbent systems are the two core technology differentiators built into each advanced biogas upgrading plant, providing considerable CAPEX and OPEX cost savings.
- Maximized Revenue. Improved Profitability. High recovery combined with the reliability of our biogas upgrading solution and our low operating costs generate significantly more profit than any competing technology.
- High Reliability. Xebec by Ivys PSAs have accumulated over 15 million hours of commercial operation with proven availabilities surpassing 99.8%.
- Ease of Installation. Ivys Adsorption delivers modularized, skidded and containerized units for simple, fast installation.
- Lowest Power Consumption. Xebec by Ivys’s low-pressure PSA operation and advanced control systems provide one of the lowest possible power consumptions levels in biogas upgrading.
How does Biogas upgrading work?
Biogas is a mixture of CH4 , CO2 , O2 , N2 and other trace gases. It is produced by the anaerobic digestion of food waste, animal manure, landfill and sewage. After the pre-treatment and purification steps, biogas is upgraded to biomethane, a renewable substitute for natural gas.

Biostream
Xebec by Ivys’s Biostream upgrading solution is a new product offering one of the most reliable and low-cost performance systems for upgrading biogas on the market.
Ivys Adsorption has conceptualized containerized and automated Biostream units, which generate renewable natural gas (biomethane) from biogas. This biogas comes from the anaerobic digestion of waste materials in municipal landfills, wastewater treatment plants, and anaerobic digesters processing agricultural and industrial organic wastes.
The Biostream unit has a capacity of 55 to 140 SCFM (90 to 225 NCMH) while the Biostream+ unit has a capacity of 55 to 280 SCFM (90 to 450 NCMH), allowing them to convert biogas into 97%+ pure biomethane, with 98.5%+ methane recovery. These units can be installed and run in parallel for higher capacities with greater flexibility and redundancy.
These innovative and scalable small-scale Biostream units consume significantly less energy when converting biogas to RNG, which supports our clients’ goal to contribute to the worldwide investment in clean energy while enhancing project profitability.
