Membrane gas solvent contactors show potential for carbon capture, because it incorporates the advantage of both solvent and membrane technology. Here, three thin film composite membrane contactors are trialed for the absorption of CO into monoethanolamine (MEA) solvent. These are prepared from coating dense poly (1-trimethylsilyl-1-propyne) (PTMSP), a Polymer of Intrinsic Microporosity (PIM-1) and Teflon AF1600 on a porous PP support. It was found that after 1h of operation, the PTMSP and PIM-1 membrane contactors provided the highest overall mass transfer coefficient, while Teflon AF1600 performance was lower. Comparison of the CO permeability through the membrane based on mass transfer ..
