Processes and systems for the capture of COfrom a CO-containing gas stream are provided. The CO-containing gas stream is passed to a membrane contactor absorber wherein the CO-containing gas contacts or passes a first side of a membrane element while a COselective solvent with a viscosity between 0.2 and 7 cP contacts, passes or flows on second side of the membrane, opposed to the first side. The COpermeates through the hollow fiber membrane pores and is chemically absorbed into the solvent.

Membrane absorption process for COcapture

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