In summary, a new method for raw biogas purification and carbon dioxide separation by a CLM was developed. The separation is based on the different solubility of components of raw biogas in a very thin, continuously refreshed water layer on/in a hydrophilic porous membrane. The permeation flux of each component of biogas depends on the feed flow rate of the gases and pressure and temperature differences between the upstream and downstream side of the CLM. The selectivity of the CLM increases with a lower feed flow rate. The molar balance based on 43 linear equations confirmed the hight potential of this method to upgrade raw biogas to natural-gas quality. The CLM can also be used under unfavorable conditions in which other polymeric membranes could be contaminated or destroyed by aggressive substances.
