The reduction of greenhouse gases will require a cost efficient method to capture the carbon dioxide in flue gas.  This project will develop a biomimetic, enzyme based, hollow fiber membrane system to remove more than 90% of the carbon dioxide from flue gas and enrich it from a feed of 3-20% to a permeate of 95-99 vol%.  This highly concentrated carbon dioxide would serve as an intermediate for a subsequent reaction to form calcium/magnesium carbonates for permanent sequestration.  Phase I will develop the enzyme-based, hollow fiber contained liquid membrane system to demonstrate high permeance and high selectivity for carbon dioxide/air.  The new design will have a guaranteed interfiber spacing to ensure operational integrity of the liquid membrane.  Water evaporation from this membrane system will be limited by coating a hydrophobic layer on the hollow fiber surface.  Lastly, the technical and economic feasibility of the membrane process will be analyzed.

 

Commercial Applications and Other Benefits as described by the awardee:  The biomimetic membrane should provide high carbon dioxide productivity and long-term operation stability under various conditions, resulting in wide application in the U.S. and abroad.
