　Production of high-quality biogas

CApureTM is an advanced technology for biogas upgrading. Removal of CO2 and H2S from biogas results in a gas quality with the same properties as natural gas.

Biogas from anaerobic treatment of wastewater sludge, organic solids and manure is a valuable sustainable energy source reducing global warming from fossil fuels. As the demand for alternative renewable energy sources is rapidly increasing, biogas will play an important part. Upgraded biogas can be used as vehicle fuel, electricity and heat production.

The CApureTM technology is based on a low pressure chemical absorption process specially designed to remove CO2 from biogas. The most important part of the CApureTM process is the absorption liquid, a especially composed amine for CO2 removal named CApureTM.


• Less than 0.1 % methane loss to atmosphere.
• Natural gas quality.
• Operation cost proportional to actual capacity.
• High purity CO2 for commercial re-use.
