Conclusion
Thus, it is shown that counter-current mode of MC operating is preferable for high separation efficiency. The proposed RMC for biogas separation provides the methane purity >95% under low energy consuming. For air dehumidification, the contactor system providing dew point below –30° C is developed. It is shown that in this case an optimum gas/liquid flow ratio is about 104. MC and RMC can be recommended for high selective separation of gas mixtures containing gaseous energy carriers.
