Item Characterization of Carbon Dioxide Removal using Ionic Liquids in Novel Geometries(47th International Conference on Environmental Systems, 2017-07-16) Arquilla, Katya; Rundle, Tessa; Phillips, Daniel; Lampe, Alexander; Shaffer, Brett; Lima, Anthony; Fritz, Trevor; Denton, Jacob; Dixon, Jordan; Holquist, Jordan; Lotto, Michael; Nabity, JamesThe Cabin Atmosphere Revitalization through Ionic Liquids (CARIL) project is part of NASA's Exploration Systems and Habitation Academic Innovation Challenge program to provide enabling technologies for future long-duration space missions. Current atmosphere revitalization technologies require frequent maintenance and spare parts – these are not manageable issues for technologies used on missions travelling to Mars and beyond. As the possibility for resupply decreases with long-duration missions, regenerable technologies become increasingly important. CARIL is focused on the characterization of the removal of carbon dioxide (CO2) from the cabin atmosphere using two different absorption bed configurations: a 3-D printed capillary-driven contactor and a hollow-fiber contactor. A flat plate contactor will be used as an experimental control, and all designs will use the ionic liquid (IL) 1-butyl-3-methylimidazolium acetate. ILs were chosen due to their low vapor pressure and selectivity between CO2 and oxygen, making them a viable option for absorbing CO2 in micro-gravity. The focus of this research is to characterize the absorption of CO2 using specific contactor materials and geometries to provide a broad range of data to analyze and inform the future development of supported ionic liquid membranes.
