The approved method for raw biogas purification from impurities and carbon dioxide separation by “condensing liquid membrane” (CLM) was verified. The hydrophilic nanoporous reverse osmosis membrane helped to form under condensing condition (below dew point of the raw biogas feed) a very thin selective water layer. Major difference in permeability of certain raw biogas components (carbon dioxide, hydrogen sulfide) and methane through water layer is responsible for high upgrading of raw biogas to biomethane quality. It represents a new approach to production of biomethane from biogas.
