Process Flow Diagram 7 NASA Ames Research Center BioEngineering Branch Figure 1.2: Conceptualized schematic of the membrane-integrated CO2 removal and compression system.4 assembly of the spacecraft (this is not shown) enters the Nafion⃝R membrane dryer where 85% of the moisture is removed. The air stream then passes to the desiccant bed, which removes any residual water. Dry air enters stage 1 of the 2 stage adsorption compressor where CO2 is removed from the process cabin air during a period of 50 minutes. Next a portion of the CO2-free air stream is pulled back, by means of a vacuum pump, through the shell side of the membrane to be rehumidified before entering the cabin. The other portion of dry air is passed through the residual water adsorber to regenerate the sorbent bed. The design and optimization of such an adsorption system requires a funda- mental quantitative understanding of the adsorption kinetics and dispersive forces 4PDF Image | TEMPERATURE SWING ADSORPTION COMPRESSION AND MEMBRANE SEPARATIONS
