Integrated CO2 Removal and Compression System Performance
(46th International Conference on Environmental Systems, 2016-07-10)
The CO2 Removal and Compression System (CRCS) is designed to perform both the CO2 removal function of the four-bed molecular sieve (4BMS) system currently employed on the International Space Station (ISS), as well as ...
Zeolite Degradation: An Investigation of CO2 Capacity Loss of 13x Sorbent
(47th International Conference on Environmental Systems, 2017-07-16)
System testing of the Carbon Dioxide Removal and Compression System (CRCS) has revealed that sufficient CO2 removal capability was not achieved with the designed system. Subsystem component analysis of the zeolite bed ...
Selection and Characterization of a Liquid Sorbent for CO2 Removal in Advanced Exploration Systems
(47th International Conference on Environmental Systems, 2017-07-16)
Removing carbon dioxide (CO¬2) from a spacecraft environment for deep space exploration requires a robust system that is low in weight, volume, power, and reliability. Extended missions beyond low Earth orbit (LEO) presently ...
Liquid Behavior through a Capillary Microchannel Contactor in a Reduced Gravity Aircraft
(47th International Conference on Environmental Systems, 2017-07-16)
A reliable, efficient, cost-effective carbon dioxide (CO2) removal and dehumidification system is needed for deep space exploration. Current CO2 removal technology on the International Space Station (ISS) utilizes solid ...
Status of the Advanced Closed Loop System ACLS for Accommodation on the ISS
(47th International Conference on Environmental Systems, 2017-07-16)
The Advanced Closed-Loop System ACLS is a regenerative life support system for closed habitats. With regenerative processes the ACLS covers the life support functions of CO2 removal, Oxygen generation and CO2 Reprocessing. ...
Energy Efficient Microlith®-based Catalytic Reactor and Recuperator for Air Quality Control Applications
(47th International Conference on Environmental Systems, 2017-07-16)
Precision Combustion, Inc. (PCI) and NASA – Marshall (MSFC) have been developing, characterizing, and optimizing high temperature catalytic oxidizers (HTCO) based on PCI’s patented Microlith® technology to meet the ...
Characterizing Cryogenic Carbon Dioxide Capture for Life Support Systems
(47th International Conference on Environmental Systems, 2017-07-16)
Without a vastly improved cabin air CO2 removal system technology, deep space missions will not be plausible. The carbon dioxide removal assembly (CDRA) on ISS has repeated replacement and maintenance costs due to adsorbent ...
Calibration and Sensitivity of a Fixed-Bed Adsorption Model for Atmosphere Revitalization in Space
(47th International Conference on Environmental Systems, 2017-07-16)
Solid sorbents offer a reliable and efficient means of carbon dioxide separation in space applications. Adsorbent-based technologies are currently used for atmosphere revitalization onboard the International Space Station ...
Solid Oxide Electrolysis and Nafion System Architecture for Oxygen Recovery and Fuel Production
(46th International Conference on Environmental Systems, 2016-07-10)
Solid Oxide Electrolysis is a technology that can generate oxygen from water vapor and carbon dioxide. Embedding Sabatier reactors allows for reclaiming oxygen from carbon monoxide produced by electrolysis as well as ...
Feasibility of Photobioreactor Systems for use in Multifunctional Environmental Control and Life Support System for Spacecraft and Habitat Environments
(46th International Conference on Environmental Systems, 2016-07-10)
Inclusion of closed-loop technologies means affordable support of long duration spaceflight missions. Photosynthetic systems can sequester carbon dioxide (CO2) to provide oxygen (O2). They offer a relatively closed-loop ...
