Examples of Physico-Chemical Life Support Systems: International Space Station

Numerous examples of physico-chemical arrangements housed within equipment on the International Space Station were surveyed. In particular, oxygen and water generation systems were discussed. The oxygen generation system is open looped system as it requires supplemental oxygen from the ground-based nitrogen/oxygen recovery system. The water generation system generally requires no supplemental system. Further, air control techniques were categorized as either active or passive systems, with the former being classified as a closed loop system. The Carbon Dioxide Reduction Assembly, which uses the Sabatier reaction, is a closed loop system. Emergency carbon dioxide removal and oxygen generation canisters are single-use only and therefore considered open loop arrangements.
