Trace Contaminant Control
Activated Carbon + Catalytic Oxidizer for VOC Removal
Trace contaminant removal via activated carbon adsorption + high-temperature catalytic oxidation removing volatile organic compounds and ammonia.
Purpose
Trace contaminant removal via activated carbon adsorption + high-temperature catalytic oxidation removing volatile organic compounds and ammonia.
Context
Child of L2-HAB-ATMO within the Lunar Ark system
Principles
- ▸Activated carbon adsorbs VOCs
- ▸Catalytic oxidizer at 400 C destroys non-adsorbed contaminants
- ▸Ammonia scrubber separately
- ▸Per ECLSS spec
- ▸Long-life replaceable cartridges
Typical implementations
- ▸ISS Trace Contaminant Control System (TCCS)
- ▸ESA MELiSSA gas conditioning
- ▸Industrial air-purification (terrestrial)
Lunar considerations
- ▸Closed-loop atmosphere requires aggressive trace removal
- ▸L1-MFG can produce activated carbon from L1-WMS-PROC-THERM
- ▸Long-life Pt catalyst
