Membrane absorption process for CO2 capture
Processes and systems for the capture of CO 2 from a CO 2 -containing gas stream are provided. The CO 2 -containing gas stream is passed to a membrane contactor absorber wherein the CO 2 -containing gas contacts or passes a first side of a membrane element while a CO 2 selective 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 CO 2 permeates through the hollow fiber membrane pores and is chemically absorbed into the solvent.
