Biogas upgrading to biomethane from agricultural waste
Biogas upgrading & H2S removal in Agriculture
Sustainable energy from agriculture and farm-based residues can be a valuable revenue stream for the farming business. Many countries are actively supporting biogas upgrading for injection in the gas grid.
At DMT we find that robust design and a simple operation works best at the farm. The system is very is to operate and the 24/7 support enhances the already very high reliability. The flexibility of the technology allows for changing circumstances and to size opportunities as they arise.
- Easy to operate, quick start-stop
- Robust & Reliable technology
- High uptimes
Agriculture & Livestock
DMT has vast experience with biogas upgrading in the agricultural industry and was the first to build a biogas upgrading plant using high selective membrane technology on a commercial plant in the United Kingdom in 2012. Agricultural residues such as crop residues and livestock wastes are very suitable sources for the production of biomethane through anaerobic digestion. Anaerobic digestion can turn these waste streams into biogas, which can be upgraded to biomethane, a renewable energy source.
Biomethane is not that different from its fossil counterpart ‘natural gas’. The biggest difference is that renewable gas also known as biomethane, is produced from the anaerobic digestion of biomass and waste. Biogas is produced through anaerobic digestion of waste from agricultural activities. Biomass, manure, crop waste and sludges are converted in into biogas and upgraded to biomethane. The biogas that mainly contains Methane (CH4 – 55%) and CO2 (45%) is purified with the use of a biogas upgrading system.
Biogas from manure
Additionally, biogas can be produced from livestock manure. Manure can be an alternative source of energy for livestock farmers. Through the anaerobic digestion process, the manure will partly be converted to energy in the form of biogas.
Livestock manure directly used as fertiliser in agriculture can cause environmental problems and natural degradation of manure leads to emissions of greenhouse gasses, methane and carbon dioxide. Therefore, the use of this resource for energy production brings both economic and environmental benefits.
- Contribution to sustainability by lowering Greenhouse gas emissions
- Economic benefit of on-site energy production
- High efficient renewable energy source
