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 has emerged as a vital solution that addresses major global challenges including managing organic waste and reducing greenhouse gas emissions. This approach supports support 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 like renewable biofuels.

The Environmental Impact of Renewable Natural Gas

Increasing awareness about the effects of GHG on the environment has paved the way for renewable natural gas plants to lower environmental impact in many industries that normally rely on conventional fuel sources. By converting organic waste into a clean energy source, RNG offers a low carbon alternative to conventional fuels.

Biogas vs. Renewable Natural Gas: What’s the Difference?

Biogas is produced through anaerobic digestion, contains methane and carbon dioxide, and can be used for heating, electricity, or as a direct fuel source.
Renewable Natural Gas (RNG) is upgraded biogas; it undergoes purification of biogas to remove impurities and increase methane content, making it compatible with natural gas pipelines and suitable for all natural gas applications.

Why is the Filtration of RNG and Biogas Important?

Filtration is a vital step in RNG and filtering biogas operations. Generated through anaerobic digestion, biogas contains methane and carbon dioxide along with harmful impurities like hydrogen sulfide, siloxanes, and moisture that can damage equipment and reduce efficiency. To protect compressors and membranes and maximize methane output, effective liquid/gas coalescence and particle filtration are essential to reduce corrosion, equipment failure and costly downtime.

Steps in RNG Filtration:

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.
