Pilot Test of a Nanoporous, Super-hydrophobic Membrane Contactor Process for Post-combustion CO2 Capture
Project No.: DE-FE0012829

GTI is building a 1 MWe equivalent pilot-scale CO2 capture hollow fiber contactor (HFC) system using polyether ether ketone (PEEK) hollow fibers in a membrane contactor. This effort represents the scale-up of technology developed a bench-scale under a previous project. The pilot-scale contactor will be tested using flue gas at the National Carbon Capture Center (NCCC). The project will demonstrate continuous, steady-state operation for a minimum of two months and gather data necessary for further process scale-up.

In this process, CO2-containing flue gas passes through one side of the PEEK HFC, while a CO2 selective solvent, Hitachi's advanced H3-1, flows on the other side. Carbon dioxide permeates through the hollow fiber membrane pores and is chemically absorbed into the solvent. The CO2 rich solvent is regenerated in a second PEEK HFC module operated in a reverse manner.  The technology under development has a cost that is 36 percent lower than DOE’s benchmark amine technology. The work can result in further maturity of this novel post-combustion CO2 capture technology.
