A Trade Study on Sabatier CO2 Reduction Subsystem for Advanced Missions 2001-01-2293
An analysis on O2 usage, water contents in food, CO2 and H2 availability, water generation capability of CO2 reduction subsystems, water balance, etc. was conducted to evaluate the feasibility of integrating a CO2 reduction subsystem into an air revitalization system.
The effects of CO2 reduction subsystem operating parameters on water recovery efficiencies and water generation capabilities were analyzed. Water mass balances for advanced missions were conducted for advanced missions. Equivalent system mass method was used to calculate payoff time for integrating the CO2 reduction subsystem into an air revitalization system. Decision criteria based on payoff time for integrating a CRS for advanced missions were developed.
