Sub-scale Adsorption and Compression CO2 Removal System Re-design

Project number: 
Academic year: 
This project required redesign of NASA’s previously developed Thermally Coupled Temperature Swing Adsorption and Compression (TS-TSAC) systems, providing an air revitalization alternative to assist in the agency’s Moon to Mars exploration objectives.

For the Moon to Mars eXploration Systems and Habitation, or M2M X-Hab, challenge, the model uses new geometry to continue the exploration of combining carbon dioxide removal and compression into one system. The system consists of two half-cycles whereby packed beds of regenerable bulk sorbents and heat cycles simultaneously adsorb and compress carbon dioxide.

The team designed the adsorption and compression beds in a cylindrical shape to maximize air flow. A desiccant helps lower humidity levels and the sorbent Zeolite 13X to capture carbon dioxide. Sensors monitor both, and a custom heater in the adsorption bed regenerates the sorbent. The experimental system is expected to scale up to 4 kg of carbon dioxide removal per day. The team produced multiple design alternatives.
