A number of amine-based carbon dioxide (C02) removal systems have been developed for atmosphere revitalization in closed loop life support systems. Most recently, Hamilton Sundstrand developed an amine-based sorbent, designated SA9T, possessing approximately 2-fold greater capacity compared to previous formulations. This new formulation has demonstrated applicability for controlling C02 levels within vehicles and habitats as well as during extravehicular activity (EVA). System volume is competitive with existing technologies. Further enhancements in system performance can be realized by incorporating humidity and trace contaminant control functions within an amine-based atmosphere revitalization system. A 3-year effort to develop prototype hardware capable of removing C02, H20, and trace contaminants from a cabin atmosphere has been initiated. Progress pertaining to defining system requirements and identifying alternative amine formulations and substrates is presented. IntroductionLong term Space Exploration missions require regenerable systems to minimize resupply logistics. Current methods of C02 removal for aerospace life support systems include non-regenerable lithium hydroxide (LiOH), and regenerable systems that employ silver oxide, solid amines or molecular sieves.[References?] In 2004 a 3-year rapid technology development project was initiated with the objective of delivering a prototype regenerable, amine-based system that combines C02, humidity, and trace contaminant (TC) control within a single system. The project team includes members from industry, academia, and NASA.
