The Effect of Adsorbent-Material Properties on PSA Based Oxygen Concentrators

Abstract

An oxygen concentrator is a technology for producing pure oxygen. By using the Pressure Swing Adsorption method, zeolite as an oxygen concentrator will absorb nitrogen in the free air and release oxygen as an output from the oxygen concentrator. This final project aims to determine the effect of the size, mass, and type of zeolite used in oxygen concentrators on the purity of the oxygen produced. Zeolite will be stored in a closed tube in this study. Experiments will be carried out with the resulting oxygen concentration parameters. The zeolite used is 13X, and Li-X. This research was conducted with mass variations of 200gr, 400gr, 600gr, and 800gr with sizes of 0.4mm and 1.7mm. The results obtained can show a comparison graph of the zeolite to the resulting oxygen concentration. The test results from the mass variation obtained that the mass variation of 800gr had higher purity in all types and sizes of zeolite. Zeolite Li-X has the highest purity value compared to 13X and the size of 0.4mm has a higher purity value compared to the size of 1.7mm.
