Testing of an Amine-Based Pressure-Swing System for Carbon Dioxide and Humidity Control
@inproceedings{Lin2007TestingOA, title={Testing of an Amine-Based Pressure-Swing System for Carbon Dioxide and Humidity Control}, author={Amy Lin and Frederick Smith and Jeffrey J. Sweterlitsch and John C. Graf and Tim Nalette and William Papale and Melissa Campbell and Sao-Dung Lu}, year={2007} }
In a crewed spacecraft environment, atmospheric carbon dioxide (CO2) and moisture control are crucial. Hamilton Sundstrand has developed a stable and efficient amine-based CO2 and water vapor sorbent, SA9T, that is well suited for use in a spacecraft environment. The sorbent is efficiently packaged in pressure-swing regenerable beds that are thermally linked to improve removal efficiency and minimize vehicle thermal loads. Flows are all controlled with a single spool valve. This technology has…
