Recovery system is comprised of three integrated subsystems: electrochemical carbon dioxide concentrator which removes carbon dioxide from atmosphere, Sabatier reactor in which carbon dioxide is reduced with hydrogen to form methane and water, and static-feed water electrolysis cell to recover oxygen from water.
Life Systems, working with NASA, has developed an electrochemical, six-man, self-contained carbon dioxide concentrator subsystem (CX-6) designed to normally remove 13.2 lb/day of CO2 while maintaining the CO2 partial pressure (pCO2) of the cabin atmosphere at 3 mm Hg or less. The CX-6 was subjected to extensive parametric and endurance testing. The effects of operating conditions on CO2 removal and electrical efficiencies were determined, including effects of hydrogen (H2) flow rate, process airflow rate, pCO2, operating temperature and current density. A total of 209 days of operation was accumulated. The subsystem was designed with self-contained electronic control and monitoring instrumentation. The CX-6 was redesigned and repackaged into the CO2 collection subsystem for the air revitalization group of the space station prototype.
A system which uses an electrochemical carbon dioxide concentrator to remove carbon dioxide from the cabin atmosphere and a Sabatier reactor to reduce carbon dioxide with hydrogen to form methane and water is described. Oxygen is recovered from water by means of a static-feed water electrolysis system. The hydrogen thus generated is reused in the carbon dioxide concentrator. The methane is a system byproduct. The CO2 removal reactions and the implementation of the CO2 concentration concept are discussed, and test results are examined.
