TLDR
In this paper, a hollow fiber membrane contactor is used to separate CO2 from a gas stream, which is a promising alternative to conventional techniques such as column absorption, and the major advantages of the membrane absorption are the larger interfacial area, better device-modularity and more operational flexibility.About:

Theoretical and Experimental Studies of CO2 Absorption in Double-Unit Flat-Plate Membrane Contactors
TL;DR: In this paper , the authors analyzed the theoretical predictions of carbon dioxide absorption flux by developing one-dimensional mathematical modeling using the chemical absorption theory based on mass-transfer resistances in series, and the CO2 absorption into monoethanolamine (MEA) solutions was treated as chemical absorption, accompanied by a large equilibrium constant.
