A single-bed rapid pressure swing adsorption process packed with 60-80 mesh zeolite 5A for enriching oxygen is investigated. For an adsorption bed of length 50.8 cm, the influence of the feed time, delay time, exhaust time, production rate and feed pressure is studied. There exists an optimal time for the feed step with a corresponding optimal exhaust time of twice the time of the feed step, and the optimal delay time is about 0.5 s. The values of the feed pressure and production rate used should depend on the oxygen purity required.
