Biogas & Renewable Energy Solutions
Biogas treatment is essential because raw biogas must be cleaned of moisture, CO2, hydrogen sulfide (H2S), siloxanes, VOCs, and other impurities before it can be used safely as renewable gas or fuel.
The global biogas market is growing rapidly. The IEA states that sustainable biogas potential is nearly 1,000 bcme, equal to about one-quarter of global natural gas demand, and overall biogas demand could double by 2035. Proper biogas treatment and methane control help reduce pollution and greenhouse-gas emissions, while poorly managed plants can emit methane equal to 2%–5.5% of output.
Biogas production converts organic waste into low-emissions renewable energy, supports residue recycling, and can also produce fertilizer and biochar from digestate. Economically, biogas enhances energy security by reducing dependence on imported fossil fuels; according to the IEA, EU biomethane already offsets about 15 kb/d of oil imports and 2 bcme of natural gas imports annually.
Through our specialized biogas division, Ion-Asia provides comprehensive gas treatment, upgrading, and purification solutions for anaerobic digestion plants, landfill gas facilities, and agricultural biogas operations across Asia and the Middle East.
Biogas purification is a critical step in converting raw gas into pipeline-quality biomethane or fuel-cell-grade hydrogen sulfide-free gas. Ion-Asia's activated carbon expertise plays a central role in Hâ‚‚S removal, siloxane elimination, and final polishing stages, complemented by our distribution partnerships for scrubbing chemicals and monitoring biosensors.
Hâ‚‚S Removal
Impregnated activated carbon and biological desulfurization systems for raw biogas treatment.
Siloxane Elimination
Specialty media beds protecting gas engines and turbines from siloxane-induced damage.
Biomethane Upgrading
Pressure swing adsorption and membrane-based COâ‚‚ separation to grid-injection quality.
Gas Quality Monitoring
Online analyzers and biosensor integration for continuous biogas composition monitoring.
Core Capability
Biogas Purification: Core Technologies
Effective biogas purification is essential for maximizing energy efficiency, protecting equipment, and ensuring environmental compliance. Ion-Asia offers specialized solutions that target key contaminants in raw biogas, transforming it into valuable biomethane or fuel-cell grade gas.
Activated Carbon
Our activated carbon media effectively adsorbs hydrogen sulfide (Hâ‚‚S), siloxanes, and volatile organic compounds (VOCs). This prevents engine corrosion and wear, significantly enhancing gas quality for combined heat and power (CHP) generation or grid injection.
Ferric Hydroxide
Ion-Asia's highly reactive ferric hydroxide is a dry scrubber media specifically designed for efficient Hâ‚‚S removal. It chemically reacts with hydrogen sulfide to form stable iron sulfide and elemental sulfur, crucial for preventing corrosion in downstream equipment.
FerroBio Biological Solution
FerroBio is a bio-reactive product that facilitates biological desulfurization, an innovative approach to Hâ‚‚S removal. Available in both powder and pellet formats, it can be applied directly in digesters or gas-phase systems, supported by our expert technical advisory.
