Biogas, Renewable Natural Gas and Flare Treatment

Biogas and Renewable Natural Gas (RNG) produced from landfills and anaerobic digestion are growing in importance as a sustainable, eco-friendly source of energy for direct use, power generation, pipeline injection and vehicle fuel.    

Biogas purification is essential for its monetization.  NORIT® activated carbon is the premier choice of engineering firms, plant owners, and operators to remove unwanted impurities to meet pipeline specifications and ensure the protection of process equipment including membranes, compressors, engines and turbines, pipelines and fuel cells.

Hydrogen Sulfide (H2S) removal

H2S removal is needed to eliminate foul odors, poisons, corrosiveness, and flammability.

Siloxane removal

Siloxane removal is needed to prevent damage, destruction and reduced efficiency to engines, turbines, fuel cells and catalysts.

Volatile Organic Compounds (VOC) removal

VOCs need to be removed from biogas to minimize damage to membranes and reduce SO₂ and NOx emissions.

Nitrogen rejection

Nitrogen rejection is needed to maintain proper BTU levels of the gas and meet stringent pipeline requirements.


NORIT activated carbon products also remove these contaminants from flare gas at landfills, wastewater treatment plants, and farm digester plants. NORIT provides the lowest-cost solution to meet stricter air emission permit limits.


NORIT technical sales and application support teams provide top-notch guidance on appropriate carbon Solutions, vessel sizing, and ongoing technical support.
