Abstract
Processes and systems for the energy efficient capture of CO2 from a flue gas stream such as produced or resulting from power plant operation, are provided. The processes and systems integrate the use of high CO2/N2 selectivity membranes and high CO2 flux membranes, to capture CO2. Useful membranes can desirably be graphene oxide-based membranes.
