Biogas and Renewable Energy
Biogas and biomethane generation offer a more sustainable alternative to fossil fuels by upcycling green waste into renewable energy. DESOTEC is proud to partner with biogas production companies to treat gas streams, protect valuable equipment, and help upgrading raw biogas to biomethane.
Biogas Production Flourishing
The biogas industry is thriving, with plants being installed at landfill sites, on farms, and at wastewater treatment plants (WWTPs) around the world.
Raw biogas is produced from organic waste through anaerobic digestion, resulting in a mixture of methane (CH₄), carbon dioxide (CO₂), and other components in varying concentrations.
Biogas purification is an essential step, and DESOTEC’s mobile sustainable filters are ideally suited to the task. Our simple plug-and-play solutions take the strain at busy sites, and are especially vital for small-scale installations lacking expert personnel on-site.
Biogas Purification to Protect Equipment and the Environment
Biogas can be used to power machinery, particularly combined heat and power (CHP) engines. To protect equipment, DESOTEC’s sustainable mobile filtration solutions remove contaminants, such as siloxanes, which are abrasive, and hydrogen sulfide (H₂S), which causes corrosion and the acidification of engine oil.
There are also health, odor control, and environmental grounds for removing H₂S, particularly to prevent the formation of acid rain. DESOTEC sustainable mobile filtration will support you in producing green power for Europe.
With the global economy striving to switch to renewable energy and find more sustainable power sources, biogas and biomethane production are booming. DESOTEC’s sustainable mobile filtration solutions are key in helping companies purify process gases and produce clean energy for a greener future.
Biogas Upgrading to Biomethane
Upgrading biogas into biomethane is generally a more efficient and cost-effective application. Biomethane is suitable for direct injection into national gas grids, or conversion into compressed natural gas (Bio-CNG) or liquefied natural gas (Bio-LNG) for transport fuel. However, to achieve the required purity of 99% CH₄, treatment is required.
Various technologies are available to separate CH₄ from CO₂ and other molecules in the gas stream. Membranes are one of these technologies, but require protection from siloxanes and other components. DESOTEC’s mobile activated carbon filtration is an effective pretreatment.
Scrubbers and bioscrubbers can also be used to remove CO₂, but are less effective at treating H₂S and volatile organic compounds (VOCs). When placed after these technologies as a polishing step, DESOTEC’s sustainable mobile filtration solution ensures that the final product is pure.
Main biogas purification needs:
- VOCs
- Siloxanes
- Terpenes
- H₂S
- Ammonia (NH₃)
How We Help You
DESOTEC Sustainable Mobile Filtration Solutions
DESOTEC’s full-service mobile filtration solutions cover everything, from purification needs assessment to waste management. Activated carbon is a Best Available Technology (BAT) for upgrading biogas into biomethane.
Our experts assess the best activated carbon type and filter for your needs, based on components, concentrations, flow rates, and other process parameters.
DESOTEC transports filtration waste in closed units away from your site. All molecules are destroyed and, where possible, carbon is reactivated, giving you a circular solution to boost your business profits and environmental responsibility. Where reactivation is impossible, waste is treated safely. Our R&D team is continually in search of new treatment solutions to further enhance sustainability.
DESOTEC helped us upgrade our biogas stream, making it usable in the main gas grid. Thanks to their flexible solution, we were able to adapt quickly.
