High purity oxygen production by pressure vacuum swing adsorption using natural zeolite

Pressure swing adsorption, which utilizes Nitrogen-selective adsorbents, is one of the well-known methods used in the design of medical oxygen concentrators. This method is applied in this work to design a smart oxygen concentrator prototype. For the first time, Natural Zeolite minerals from Jordan are studied as a Nitrogen -selective adsorbents for medical oxygen concentrator's production. Considering the patients' safety and end-user's convenience the proposed prototype is outfitted with a cutting-edge IoT technology, allowing monitoring for the patient's blood Oxygen level and the Oxygen percentage produced by the concentrator. In order to accomplish the concentration level requirements for medical-grade Oxygen, the Oxygen concentrator prototype can efficiently supply a stream of Oxygen that is 93% volume enriched. Three collected natural samples from different geographical parts of Jordan have been appropriately prepared, studied and tested in order to deter-mine the most appropriate zeolite material to be used, the results show that the obtained samples have resulted in O2 production as follows: Jabal Aritayn (NE of Azraq) 78%-80%, Tal-Al Rimah (NE Mafraq) 86%-88%, Jabal Ata'atah (SE Tafila) 91%-93% at 7 L/Min.
