Biogas Purification
Supporting Sustainable Energy
For the transition to sustainable energy production, biogas is an excellent complement to energy from the sun and wind. Biogas is produced during the natural decomposition of organic material by bacteria in a process known as anaerobic digestion. Biogas is also generated when the sun and wind are not active. Renewable and powerful, biogas is a sustainable alternative to fossil natural gas. It can be used to generate electricity, heat, or fuel. The remaining digestate is suitable as fertiliser and allows new energy crops to flourish. A perfect cycle.

New OX Series Activated Carbon Pellets
All the benefits of carbon pellets. All the sustainability of coconut shell.
Jacobi’s GO GREEN initiative seeks to replace all fossil-fuel derived products in our portfolio with sustainable alternatives. With this ongoing mission in mind, Jacobi is offering our AddSorb OX Series pellets for the removal of hydrogen sulfide.
Why coconut shell?
Coconut shell provides the most sustainable raw material in the activated carbon market, and provides over 54% lower global warming potential than activated carbons derived from coal. And Jacobi’s CleanTech char technology is being rolled out through our supply chain to drive emissions even lower. Using this product can help lower your Scope 3 emissions and reduce your CO2 footprint. See our sustainability reports for more details.
Our Biogas Solutions
Hydrogen sulphide (H₂S) removal from Biogas
Biogas is produced by the digestion of organic matter in landfills and anaerobic digesters. Hydrogen sulphide (H₂S) is formed during the anaerobic digestion of sulphur-containing molecules, such as sulphur-containing amino acids within proteins.
The Jacobi Services mobile filter solutions, filled with carefully selected media, are used to remove hydrogen sulphide (H₂S) prior to the combustion engines or turbines. On combustion of the biogas, H2S can be converted into sulfur dioxide or sulfur trioxide (SO₂ or SO₃ respectively), and will result in:
- Higher maintenance cost due to corrosion
- A negative effect on the engine oil, meaning it needs to be changed more frequently
- A contribution to the SO₂/SO₃ emissions of the engine exhaust
Siloxanes removal from Biogas
Siloxanes present in biogas will burn in the gas turbine or combustion engine to form silica in the form of silicon dioxide (SiO₂) or silicates (SiₓOy). This silica and silicate will build up on valves, cylinder walls, liners, and on the turbine blades, causing abrasion, blockages, and mechanical failure of the equipment. This build-up will lead to:
- Higher maintenance cost
- Changing oil more frequently (often more than twice the expected frequency)
- Replacing valves and cylinders
- Engine power loss (often in the range of 10 – 20%)
- Decreased profitability
- Increased capital cost
- Total mechanical failure or breakdown of the combustion engine
The Jacobi Services mobile filter solutions filled with carefully selected media are used to remove siloxanes from combustion engines or turbines to avoid silicate build up and high costs.
Terpene removal from Biogas
Terpenes are another of the unwanted impurities in the biomethane production process and must be removed prior to injecting into the grid, as they also create a number of issues, including:
- Corroding gaskets and plastic piping (PE)
- Masking the Tetrahydrothiphene (THT) odour component that is added to the biomethane for leakage detection
Terpenes are normally only targeted when the biogas is used to produce biomethane. The Jacobi Services mobile filter solutions filled with carefully selected media are used to remove terpenes prior to injection into the natural gas grid.
Ammonia Removal from Biogas
Ammonia removal in biogas treatments is essential to prevent issues such as corrosion and catalyst poisoning in downstream processes. Our activated carbon can help you to effectively eliminate ammonia from the biogas stream. This not only improves the overall quality and energy content of the biogas but also ensures safer and more sustainable operation of the treatment system.
Hydrogen sulphide (H₂S) removal from CO₂ enriched air
Biogas can be upgraded to biomethane, that can then be fed directly into the natural gas grid or used as a vehicle fuel to reduce greenhouse gas emissions by separating the carbon dioxide (CO₂)/methane (CH₄) mixture.
Water washing is one of the more popular methods of biogas separation. This is effective as carbon dioxide is soluble in water and methane is almost insoluble. The carbon dioxide is absorbed at high pressure in the water and desorbed from the water at lower pressure and in presence of an airflow. This air flow will also take up hydrogen sulphide (H₂S) present in the water, which causes the typical rotten egg smell when released into the environment.
Hydrogen sulphide (H₂S) is therefore removed from the carbon dioxide (CO₂) enriched air using the Jacobi Services mobile and/or fixed filters with activated carbon prior to discharge into the environment to avoid disruption to workers and neighbours.
