There is a great concern about green house gases (GHG) impact on the global climate mitigation and numerous studies aim at the reduction of GHG emissions. Among targeted gases (VOC, CH4), carbon dioxide remains actually the main objective because its emission is strongly associated with the industrial development and with the energy production from fossil sources which, up to now, cannot be quickly substituted by any other sources except by nuclear energy. If they are many types of stream containing CO2, one can easily classify them into two main categories according to their pressure and temperature ranges that can be either high (P > 50 bar, t° > 200°C) or low (P < 2 bar, t° < 150°C); generally speaking these cases are known as pre-combustion or post-combustion. The work reported in this study is dedicated to the postcombustion case and polymer based membranes able to improve CO2/N2 capture from flue gas were studied from readily available glassy polymers.
