A new solid amine system effectively concentrates and collects carbon dioxide (CO2) for spacecraft, achieving 95% concentration and 90% collection efficiency for life support.

Area of Science:

  • Spacecraft Environmental Control and Life Support Systems (ECLSS)
  • Chemical Engineering
  • Carbon Capture Technologies

Context:

  • Long-duration space missions require efficient carbon dioxide (CO2) removal from crewed spacecraft cabins.
  • Existing CO2 control systems face challenges in concentration and collection efficiency, impacting system longevity and resource management.

Purpose:

  • To develop and validate a solid amine-based CO2 concentration and collection system for spacecraft.
  • To address the limitations of current CO2 removal technologies in space applications.

Summary:

  • A novel apparatus utilizing absorption and desorption principles was designed and tested for CO2 management.
  • The system achieved an average CO2 concentration of 95%, suitable for direct use in CO2 reduction systems.
