Biogas purification using condensing water membrane
Original language description
Recently, the purification of a raw biogas has attracted a great attention from the researchers. The possibility of effective waste utilization for renewable biofuel production has enormous ecological and economic benefits. In this paper, a water-swollen thin film composite membrane for effective separation of CO2 and H2S from methane in biogas is presented. The hydrophilic polyamide reverse osmosis membrane covered with water coming as condensate from the biogas acts as a thin selective separation layer through which water-soluble compounds as CO2 and H2S can be separated from methane. The biogas saturated with the water vapor was brought into a contact with the spiral wound membrane in order to preserve the selective skin layer. Under these conditions, the retentate stream containing 94.4 vol % of biomethane was obtained. Contribution in the proceedings to the conference Den doktorandů 2021.
