The use of rapid pressure swing adsorption to enhance the design of portable medical oxygen concentrators

Abstract

Portable oxygen concentrators are restricted by three main factors: power consumption, weight and output. To minimise the weight and output of a portable oxygen concentrator. This paper investigates how rapid pressure swing adsorption will improve oxygen yield per unit volume of adsorbent. It was observed through experimental data the rapid pressure swing adsorption cycle developed in this research could achieve a throughput of 50 sccm, using adsorbent Zeox Z12-49, in one 6.4mm diameter column of 140mm in length, which is a four times improvement when compared to leading market devices.
