The experimental study on the performance of a small-scale oxygen concentration by PSA

A small-scale adjustable rich oxygen concentrator by pressure swing adsorption (PSA) was designed and manufactured to study influences of nozzle size and purge quantity on characteristics of the production oxygen, such as its pressure, purity and volume flux. This device could reach above 90% and up to 97% in volume. The flux of rich oxygen product could be adjusted intelligently in the range of 0.5 l/min-3.5 l/min. The device can operate continuously and stably over two years and is quite usable in hospital, domestic application, oxygen bar and other places in shortage of oxygen.
