Abatement of CO2 emissions by means of membranes - characterization of industrial PebaxTM films

The present work aims at prospective use of industrially available PebaxTM resin breathable films (Arkema) as membranes for CO2 separation from flue gas. The time-lag permeation and the microgravimetric techniques were used for the determination of the diffusion, sorption and permeation through PebaxTM 1074, 6100, 1657 and 3000 extruded films. The results indicate that the whole series of PebaxTM films is highly permeable to CO2 with the best value for the 6100 member, with a permeability coefficient of 100 barrers. In comparison with other polymer materials, the higher PebaxTM permeability to CO2 is due to higher values of both the sorption and the diffusion coefficients.
