At present, there are three main methods of biogas purification: chemical absorption, physical purification and biological removal. Biogas is the product of anaerobic fermentation of organic matter, which is a combustible mixed gas. No matter where biogas purification is used, it is necessary to remove H₂O and H₂S in raw materials to avoid pipeline corrosion and cause great harm.
