Simultaneously, this water– swollen membrane is able to remove carbon dioxide, hydrogen sulfide and water vapour fro agro-biogas. A unique feature of the presented approach, distinguishing the water-swollen thinfilm composite membranes from polymeric membranes under dry conditions, is that the condensing water absorbs a significant amount of minor impurities of biogas, such as H2S and CO2. Therefore, a significant amount of carbon dioxide and hydrogen sulfide can be successfully removed from the feed stream under mild conditions (temperature of 21 °C and pressure of 220 kPa).
