Abstract
Important parameters in designing regenerable adsorption beds for spacecraft life support systems are defined. Typical applications include synthetic zeolite, which is used for carbon dioxide removal; and silica gel, which dehumidifies the atmospheric gas prior to passing it through the zeolite beds.
Bed performance is evaluated from correlated test data. A linearized solution of the dymanic mass transfer equations is presented, which provides a simplified method of bed design. This method is used to find the optimum design for a typical four bed regenerable, isothermal, carbon dioxide removal system. Results of this simplified analysis are compared with those of a detail digital computer study. This comparison indicates that the simplified method predicts system weight approximately 10% higher than the detailed evaluation.
