DESIGN AND FABRICATION OF OXYGEN CONCENTRATOR GENERATOR BY USING PRESSURE SWING ABSORPTION SYSTEM (PSA)

Oxygen is used in a variety of chemical processes and for medical purposes throughout the world. Pressure swing adsorption (PSA) has come a doable volition to cryogenic distillation for the separation of oxygen from air with the development of advanced adsorbents like zeolites. PSA processes are constitutionally complex because it’s a dynamic process. Effective operation of a PSA process is necessary in order to use the capacity of the adsorbent as much as possible and reduce the power conditions of the process. Medical oxygen concentrators are used for supplying medical grade oxygen to help hypoxemia- related complications related to COVID- 19, habitual obstructive pulmonary complaint (COPD), habitual bronchitis and pneumonia. Medical Oxygen Concentrator constantly use a technology called pressure swing adsorption (PSA), which relies on nitrogen-picky adsorbents for producing oxygen from ambient air. Medical Oxygen Concentrators are constantly designed for fixed product specifications, thereby limiting their use in meeting varying product specifications caused by a change in case’s medical condition or exertion. To address this limitation, we design and optimize flexible single- bed MOC systems that are suitable of meeting varying product specification conditions. Specifically, we employ a simulation- predicated optimization frame for optimizing flexible PSA- and pressure vacuum swing adsorption (PVSA)- predicated MOC systems. Detailed optimization studies are performed to standard the performance limits of LiX, LiLSX and 5A zeolite adsorbents. The results indicate that LiLSX outperforms both LiX and 5A, and can produce 90 pure oxygen at21.7 L/min.
