Integrated CO2 Removal and Compression System Performance

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 additional integrated ability to purify and thermally compress CO2 to supply downstream CO2 recovery units. The CRCS approach will reduce cost and improve reliability for future long-duration missions. Previously, data has been presented for testing of a single unit of the 2-Stage Compressor. Data from those tests was used in the assembly a second unit and integration into a two unit system. Operation of the integrated two unit system will be described.
