Our reliable, patented technology is an environmentally safe deoxo solution for eliminating oxygen from biogas streams, including dairy and swine farms as well as Landfill Gas (LFG) operations. Purifying biogas from oxygen is a critical step in upgrading raw biogas to Renewable Natural Gas (RNG).
With several models for different gas processing capacities combined with its modular design, ZerO2 is the most flexible and scalable catalytic deoxo solution for biogas projects of all sizes.
ZerO2 units are modular and can be connected easily to align oxygen removal (dexo) capacity to your needs.

Why Do Natural Gas Pipelines Impose Strict Oxygen Limits? Natural gas pipelines operate under carefully defined gas quality standards designed to protect infrastructure, ensure safety, and maintain reliable energy delivery. Among the most important of these standards are limits on oxygen concentration. Most pipeline operators impose strict oxygen specifications, typically measured in parts per…
Managing Oxygen Corrosion Risk in Natural Gas Pipelines with ZerO2 Oxygen is a contaminant that can quietly threaten natural gas pipeline integrity, creating the conditions for catastrophic pipeline failures with consequences for safety, assets, and business continuity. Even in small concentrations, oxygen can significantly accelerate every form of corrosion in steel oil and gas pipelines,…
