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.
H₂S Removal with DARCO BG1
NORIT's DARCO BG1 is a leading solution for removing hydrogen sulfide (H₂S) from vapor phase gas streams, ensuring cleaner and safer biogas and renewable natural gas (RNG). This non-impregnated, lignite-based, granular, steam activated carbon is designed for high sulfur loading, effectively reducing H₂S to elemental sulfur and removing mercaptans and siloxanes. Its extensive surface area and pore structure make it highly efficient. DARCO BG1 is safe, non-exothermic, and easy to change out, making it a reliable choice for various applications.
Flare
Treatment
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.
