4. Conclusion and outlook

This study on the efficiency of dense-skin membrane contactors was carried out with a CO ₂ /N ₂ gas mixture modeling the afterburner case, without however taking into account the full complexity of industrial flue gases, linked in particular to the presence of water vapour, ancillary gases present at low levels (O ₂ , SO _x , NO _x ), nor the dust pre-treatment that will be necessary whatever the type of G/L contactor envisaged.
