Experimental And Simulation Studies Of An Oxygen Concentration System Using Pressure/Vacuum Swing Adsorption Technique: System Miniaturization And Prototype Design, Mingfei Pan
Electronic Thesis and Dissertation Repository
The miniaturization of a pressure swing adsorption (PSA) oxygen concentrator is of prime significance for portable applications. This work presented a simplified pressure/vacuum swing adsorption (PVSA) cycle with a concentrator prototype design using a deep evacuation step (-0.82 barg) instead of desorption with purge flow to improve the efficiency of oxygen production process and miniaturize the size of the concentrator. The output of the oxygen concentrator is a 50-90 vol.% enriched oxygen stream in a continuous adsorption and desorption cycle (cycle time = 75-90 s). The size of the adsorption column is 3 cm in diameter and 20 cm in …
