CO2 removal system for Manned Mission beyond LEO using deep space radiators and solar heaters
(46th International Conference on Environmental Systems, 2016-07-10)
The current spacecraft technology to remove CO2 generated in manned missions uses mostly zeolite filters, which break down relatively easy; this has caused multiple problems over the last decades. The current solution has ...
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 ...
Progress on the CO2 Removal and Compression System
(45th International Conference on Environmental Systems, 2015-07-12)
The Carbon Dioxide Removal and Compression System (CRCS) is designed to perform both the Carbon Dioxide (CO2) removal function of the four-bed molecular sieve (4BMS) system currently employed on the International Space ...
A Trade-off Study of the Spacecraft Carbon Dioxide Management System using the Analytical Hierarchy Process
(48th International Conference on Environmental Systems, 2018-07-08)
A Carbon Dioxide Management System (CMS) trade study was conducted to compare the
Sabatier Assembly Compressor (SAC) used on the International Space Station (ISS) with the Air-Cooled Temperature Swing Compression System ...
Power Optimization of Cryogenic CO2 Deposition Capture in Deep Space
(2020 International Conference on Environmental Systems, 2020-07-31)
An extremely reliable cabin air revitalization system is needed for human deep space exploration missions. Deep space offers an environmental temperature close to 4 Kelvin. This low environmental temperature enables heat ...
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 ...
Modeling Performance of the Full Scale CO2 Deposition System
(50th International Conference on Environmental Systems, 7/12/2021)
To enable long-duration manned travel to the Moon and/or Mars, a highly reliable spacecraft cabin atmosphere revitalization system is required. One new carbon dioxide capture system currently in development is the CO2 ...
The Integrated Carbon Dioxide Removal, Compression, and Storage (CRCS) System
(47th International Conference on Environmental Systems, 2017-07-16)
The Carbon Dioxide Removal, Compression, and Storage (CRCS) system was designed to remove carbon dioxide (CO2(g)) from the spacecraft cabin atmosphere and compress and store the CO2(g) for further processing. Previous ...
Numerical Characterization of Spacecraft Cabin Air Dehumidification System for CO2 Removal
(50th International Conference on Environmental Systems, 7/12/2021)
An extremely reliable, low maintenance cabin air revitalization system is required for manned deep space exploration missions. The CO2 deposition system (CDep) addresses this challenge. A cold surface is generated and ...
Performance of Silica Gel in the role of Residual Air Drying, Part II
(46th International Conference on Environmental Systems, 2016-07-10)
Removal of carbon dioxide (CO2)is a necessary step in air revitalization and is often accomplished with sorbent materials. Since moisture competes with CO2 in sorbent materials, it is necessary to remove the water first. ...
