(652d) Design and Scale-up of Tvsa Cycle for CO2 Removal from Spacecraft Cabins Using a Structured Adsorbent
An extensive bench scale experimental study is being carried out around the base case separation that meets or exceeds the required CO2 removal rate for four astronauts. This removal rate is 1 kg of CO2 per day per astronaut. This corresponds to processing around 740 SLPM of a feed steam containing 2,700 ppm of CO2 and removing 68.5 % of this CO2. The effects of the feed flow rate, CO2 concentration, cycle time, regeneration temperature and low vacuum pressure on the process performance are being investigated. DAPS will utilize these bench scale experimental results to design and scale up a new column utilizing the IM structured adsorbent. The latest results of this project will be presented.
