What is decarbonization？

Biogas is a colorless, odorous, toxic gas, its main components are CH4 and CO2, in addition to CO, H2S, NH3, O2 and so on. The volume fraction of CH4 is usually 50% - 75%, the volume fraction of CO2 is 30% - 40%, and the sum of other gases is generally less than 2%. The purified biogas enters the biogas compressor first, and the biogas pressure rises to 0.6MPa. After passing through the buffer tank, it enters the decarbonization unit and dehydration unit...
