MEA Triazine H2S Scavenger for Biogas & Biomethane Purification
MEA Triazine 78% removes H2S from biogas, landfill gas, and anaerobic digester output. Protects engines, turbines, and upgrading equipment. Supplied by Vasudev Chemo Pharma, India.
The H2S Problem in Biogas
Biogas produced from anaerobic digestion of organic waste, wastewater sludge, agricultural residues, and landfill decomposition typically contains hydrogen sulfide at concentrations ranging from 100 to over 10,000 ppm. This H2S originates from the bacterial reduction of sulfate and the decomposition of sulfur-containing proteins in the feedstock.
Untreated H2S in biogas causes rapid corrosion of engines, turbines, piping, and biogas upgrading equipment. It also poses a direct safety hazard to plant operators and produces sulfur dioxide (SO2) emissions when combusted — a regulated air pollutant. For biogas upgrading to biomethane or renewable natural gas (RNG), pipeline injection specifications typically require H2S below 4 ppm, demanding effective and reliable removal technology.
MEA Triazine for Biogas H2S Removal
MEA Triazine 78% is an effective liquid H2S scavenger for biogas applications. It is injected into the biogas stream — typically in a packed scrubbing column or inline injection system — where it reacts irreversibly with H2S to form dithiazine, a water-soluble and non-toxic by-product.
For smaller biogas plants (agricultural digesters, small landfills), MEA Triazine offers a simple, low-capital solution: a chemical dosing pump and a contact vessel are the only equipment required. For larger operations, MEA Triazine can be used as a polishing step after biological desulfurisation or iron-based removal to achieve the stringent H2S limits required for biomethane upgrading and grid injection.
The 78% active concentration minimises chemical consumption and reduces the frequency of chemical deliveries — an important consideration for biogas plants in rural or remote locations. The spent solution is non-hazardous and can typically be disposed of through the existing wastewater management system at the biogas facility.
