Biogas Upgrading

Methane purification technology with Biogas

Biogas is a kind of environment-friendly, clean and cheap combustible gas produced by microorganism in anaerobic environment, such as livestock manure, agricultural waste, industrial organic waste, domestic sewage and municipal solid waste. The main components are methane, carbon dioxide and hydrogen sulfide. Biogas is mainly purified and purified for city gas, vehicle fuel and hydrogen production.
