Integration of large-scale pressure swing adsorption units in local hospitals in Morocco: Design, simulation and performance evaluation

To enhance the availability and accessibility of medical oxygen in local hospitals in Morocco, a solid approach has been conducted for upscaling PSA unit. This comprehensive research involves the design, simulation, and performance evaluation of the PSA unit to confirm the functioning and efficiency of the system. The design phase meticulously considers hospital oxygen requirements, utilizing data from multiple local hospitals. Objectives include using PSA technology to produce high-purity oxygen, providing autonomy for 30-35 patients at 5 L/min. Although, the hospital needs 650 L/min of medical oxygen in order to supply all the patients. The study reveals promising results for oxygen concentration which reaches a maximum of 96 % of oxygen under 29 mol/min of flowrate which give an equivalent to 660 L/min volumetric flow rate that can supply the needs of local hospitals within a short time. These findings will enable hospitals decision makers to consider large PSA over cryogenic separation unit that has been known with major drawbacks in delivery and pose logistical and environmental problems and to ensure a steady and reliable supply of medical oxygen, ultimately contributing to improved healthcare services and patient care.
