Oxygen removal from biogas

HyGear offers proven and in-house developed De.OXO systems with oxygen (O2) removal technology from two gas streams: biogas and hydrogen. The De.OXO Biogas system provides a tailored solution for managing oxygen content in biogas, a critical requirement in the US bioenergy sector. Biogas plants and anaerobic digestion systems typically introduce small amounts of oxygen for sulfur removal. Yet, the strict regulations on oxygen content enforced by certain US states create logistical challenges when transporting biogas across state lines for grid injection. Looking for oxygen removal from hydrogen?

Deoxygenation Before Upgrading 

The De.OXO system of HyGear is a compact, autonomous system designed to conduct deoxygenation – the removal of oxygen from biogas – before the biogas upgrading process. This critical deoxygenation step, occurring before biogas is converted into renewable natural gas (RNG), not only streamlines the entire process but also reduces the need for extensive transport and manual labor. It boosts the purity and value of your biomethane, too.
