Methane upgradation is the extraction of methane from carbon dioxide and other gases from biogas.
Methane in biogas is comparable to levels that are those of natural gas using a biogas upgrading facility. One technique for doing this is the treatment of amine gas. This purified biogas can be called biomethane.
Methane upgradation Techniques:
Stripping CO2
H2S from biogas
