Abstract

A novel, single-bed, 4-step, Rapid Pressure Swing Adsorption (RPSA) process is designed for producing 90% O₂ from compressed air for medical use by patients with Chronic Obstructive Pulmonary Disease (COPD) and other lung disorders. The proprietary design integrated with product storage tank is capable of continuously producing 1 - 3 LPM of ∼ 90±% O₂ by employing a commercial sample of LiLSX zeolite as an adsorbent for air separation. An optimum cycle time of 4-6 s was identified from the experimental results at which a lower Bed Size factor (BSF) of ∼ 41 kgs/TPD02 and corresponding oxygen recovery (R) of ∼ 29 % were obtained. An optimum adsorbent particle size range was also identified by simulating the RPSA process. Thus, the transformative design of medical oxygen concentrator (MOC) using RPSA Technology has a potential to reduce the adsorber size by a factor of 2 to 3 while offering similar or -10% higher O₂ recovery.
