Transformation technologies for Biogas to biomethane


Biogas is considered as potential option for the replacement of conventional fuels due to its environment friendly and contains less carbon footprint upon use. Conversion of biogas to biomethane leads to increase of applicability such as, transport, heat and electricity. Biomethane from biogas can be obtain from various available technologies such as adsorption, absorption, membrane separation and cryogenic. Out of which physical absorption is considered as economical viable technology till date. In this paper, attempts have been made to discuss various biogas purification technologies, which are widely used all over the world. The widely accepted technologies have been with more prominence on their operation, merits and demerits and their future scope are also discussed.
