The AC-TSAC would be integrated downstream of the Four-Bed Molecular Sieve (4BMS) CO2 removal system and upstream of the Sabatier reactor system. The previous generation of the AC-TSAC system was dismantled and has undergone a significant upgrade to modernize the system and resolve system failures.application/pdfengAC-TSACTSACAir RevitalizationCO2Carbon dioxideAir CooledAdsorptionSolid adsorbentAmesARCcompressorcompressionsolid statesorbentPresentation
