A Brief Overview of Compressed Biogas

Biogas, obtained from the anaerobic decomposition of organic waste like cattle dung, agriculture residue, municipal solid waste, sugarcane press mud, sewage treatment plant, and other such sources of biomass, is rich in energy. The primary constituents of biogas are methane (60%), carbon dioxide (40%), and particles of hydrogen sulfide. It is possible to use raw biogas as fuel directly or purify and upgrade the gas by eliminating H2S (Hydrogen Sulfide) and CO2 (Carbon Dioxide) while increasing the presence of methane to obtain CBG (Compresses Biogas). CBG, with over 90% methane content, is similar to CNG (Compressed Natural Gas) in terms of energy potential and composition. Biogas Purification Using biogas as renewable natural gas highly depends on the methane concentration of the gas. Thus, purifying raw biogas in a biogas bottling plant is important to eliminate the corrosive impact of hydrogen sulfide and increase the energy per unit volume of CBG. Overall, the process of purificati
