A solid-amine water (steam) desorbed (SAWD) carbon dioxide removal subsystem is a candidate for use on the proposed U.S. Space Station for removing carbon dioxide (CO2) from the spacecraft cabin atmosphere. To evaluate the long-term stability of the solid amine resin, IRA-45, with respect to repeated CO2 absorption and steam desorption cycling, an automated laboratory flowtest facility was assembled. Packed columns of IRA-45 resin were tested under simulated Space Station cabin conditions for 569 cycles to determine the decrease in CO2 absorption capacity as a function of the number of cycles and the volatile organic compounds released by steam desorption cycling. Carbon dioxide capatcity was measured in real-time during each cycle. Organic volatiles in the resin-desorbed CO2 and in the simulated cabin air flow were trapped on graphitic carbon adsorbents. Analyses of the trapped volatiles were performed using gas chromatography (GC) and mass spectrometry (MS).
