Renewable Natural Gas (RNG) & Biogas Filtration Solutions
Reliable biogas filtration and purification solutions help remove harmful contaminants, protect critical equipment, and support efficient Renewable Natural Gas production.
Unlocking the Power of Renewable Natural Gas (RNG) for a Sustainable Future
As the world intensifies efforts to combat climate change, renewable natural gas (RNG) has emerged as a vital solution that addresses major global challenges including managing organic waste and reducing greenhouse gas emissions. Biogas produced through anaerobic digestion can be upgraded into Renewable Natural Gas (RNG) through purification, increasing methane content and making it suitable for natural gas applications.
This approach supports broader decarbonization initiatives across industrial sectors while offering a low carbon alternative to conventional fossil fuels.
By converting organic waste into a clean energy source, RNG delivers a reliable pathway toward cleaner operations and complements other sustainable energy options such as renewable biofuels.
Why is Filtration of RNG and Biogas Important?
Filtration is a vital step in RNG and biogas operations. Biogas contains methane and carbon dioxide along with impurities such as hydrogen sulphide, siloxanes and moisture. Effective liquid/gas coalescence and particle filtration are essential to help protect compressors and membranes while reducing corrosion, equipment failure and costly downtime
Steps in RNG Filtration:
Throughout the RNG production process, contaminants including moisture, particulates and other impurities can affect equipment performance and operational reliability. Effective filtration helps protect critical assets involved in biogas upgrading and RNG production while supporting efficient operation. The process flow above highlights the journey from raw biogas to renewable natural gas, with filtration playing an important role in helping protect equipment and reduce the impact of contaminants throughout the process.

What Is a Biogas Filtration System?
A biogas filtration system combines liquid/gas coalescers and high efficiency biogas filters to remove liquids and particulates before upgrading. This protects critical assets, supports stable pressure drop and flow, and improves overall plant reliability.
Quick definition Biogas filtration removes particulates, liquids and corrosive compounds (e.g., H2S, siloxanes, moisture) so only clean gas reaches upgrading equipment, helping protect compressors and membranes and support methane recovery.
Frequently Asked Questions
What is biogas filtration?
It is the removal of particulates, liquids and corrosive compounds before upgrading, to protect equipment and support efficient RNG production.
How do you filter biogas?
Use liquid/gas coalescers and particulate filters to remove moisture, aerosols and solids prior to upgrading.
What impurities are typically removed?
Biogas filtration targets hydrogen sulfide, siloxanes, moisture and particulates; CO2 is reduced during upgrading to reach RNG quality.
What does a biogas filter do?
A biogas filter captures fine solids to prevent fouling and damage to compressors and membranes.
What is a biogas purifier?
A biogas purifier provides final conditioning to help upgraded gas meet RNG specifications.
