Oxygen Concentrator Design: Zeolite Based Pressure Swing Adsorption †

Abstract

The ongoing coronavirus and its variants are alarming the world inadequately. Extreme reciprocal pneumonia is the primary element of serious COVID-19, and sufficient ventilator help is vital for patient endurance. Supplemental oxygen is the first fundamental stage for the cure of serious COVID-19 patients with hypoxemia. In this regard, oxygen concentrators can be used for patients of COVID-19 to supply oxygen. This paper primarily focuses on designing a portable medical device oxygen concentrator using the technology pressure swing adsorption (PSA), which takes air from the atmosphere, adsorbs nitrogen, and supplies oxygen. A detailed study with the simulation has been done to benchmark the outcome of LiX, LiLSX, and 5A zeolite as adsorbents. Results show LiX is the most suitable with better nitrogen to oxygen selectivity ratio with a flow rate of 5LPM.
