External Desulphurisation

For almost any gas stream affected by hydrogen sulphide—from biogas and landfill gas to natural gas and industrial off-gases—the FerroSorp® S range provides a robust and highly effective adsorption solution. Its advanced iron-hydroxide formulation makes it an important technology to consider for dependable H₂S control.

Zorbia is the exclusive distributor for HeGo Biotec International GmbH in Australia, New Zealand, and Papua New Guinea. As a sister company to HeGo Biotec GmbH (est. 1990), HeGo Biotec International specialises in state-of-the-art environmental protection products—particularly high-performance adsorbents and reactants based on iron hydroxide for gas and wastewater treatment.

 

HeGo Biotec is the original manufacturer of the FerroSorp® range—industry-leading media for H₂S removal.

 

FERROSORP® S – HIGH-EFFICIENCY H₂S REMOVAL MEDIA

FerroSorp® S is a pelletised gas purification compound with a high amorphous iron hydroxide content, offering strong reactivity and selectivity toward hydrogen sulphide and high removal efficiency. It delivers high loading rates, low pressure drop, and outlet concentrations as low as 0 ppm H₂S (even into the ppb levels for some applications).

​

Available in multiple grain sizes and configurations, FerroSorp® S can be tailored to your specific process requirements—including partial H₂S removal to controlled concentrations such as 300 ppm.

​

Key Benefits:

  • Proven performance over 20+ years, currently in operation at over 2500 sites worldwide

  • Extremely high H₂S loading capacity

  • Minimal pressure drop due to optimised pellet shape

  • Economic alternative to traditional desulfurisation systems

  • Customisable for full or partial removal targets

  • Achieves 0 ppm H₂S at the outlet

  • High performance in gases without air/O2

  • Can be utilised as a fertiliser (this is dependent on the other impurities in the gas and the jurisdictional rules of the location)

  • Easy to handle during change-out

​

Common Applications:

  • Biogas desulfurisation (external systems)

  • Waste fermentation gas treatment

  • Landfill gas and sewage gas purification

  • Odour control systems

  • Natural gas

  • Industrial syngas, CO₂, and pyrolysis gas streams

  • Natural gas conditioning and upgrading

​

How It Works: FerroSorp® S is used in fixed, or moving-bed reactors, where it reacts with H₂S to form solid iron sulphide. A second reaction, using dosed air or oxygen, regenerates the media by converting sulphides to elemental sulphur, thereby maintaining maximum efficiency.

​

Zorbia can also perform H₂S tolerance studies to determine the safe combustion limits for your equipment—such as boilers, gensets, or fired heaters—to optimise performance without compromising reliability or lifespan.

Get in Touch

If you’re looking for a more economical, more reliable H₂S removal solution than activated carbon, iron oxide, or iron sponge, FerroSorp® is worth serious consideration. Our external desulphurisation systems delivers high purity, stable removal efficiency, longer media life, and lower operational hassle—making them ideal for biogas, landfill gas, syngas, odour and industrial applications.
