Membrane technology for CO2 separation has been intensively developed to reduce capture cost compared with amine-sorption technology in post combustion CO2 capture of conventional power plants. However, the previous researches have been focused on the material development and lab-scale level experiments, so that the large scale production and operation of thin-film composite membranes under real gas condition have hardly been verified worldwide. In this study, we will propose several approaches to prepare large-scale (22cm x 34cm) CO2 separation membranes using graphene oxide(GO) and highly CO2-selectively permeable polymer composite material as well as their gas transport properties. In addition, the membranes were fabricated into the bench-scale plate-and-frame membrane module, which has membrane area about 15,000 cm2, and the CO2 separation properties of the membrane module will be discussed in this study. |
