Amine Swingbed Payload Technology DemonstrationThe Amine Swingbed is an amine-based, vacuum-regenerated
adsorption technology for removing carbon dioxide and humidity
from a habitable spacecraft environment, and is the baseline
technology for the Orion Program’s Multi-Purpose Crew Vehicle
(MPCV). It uses a pair of interleaved-layer beds filled with SA9T, the amine sorbent, and a linear multiball valve rotates 270° back and forth to control the flow of air and vacuum to adsorbing and desorbing beds. One bed adsorbs CO2 and H2O from cabin air while the other bed is exposed to vacuum for regeneration by venting the CO2 and H2O. The two beds are thermally linked, so no additional heating or cooling is required. The technology can be applied to habitable environments where recycling CO2 and H2O is not required such as short duration missions.
