Mathematical models have been developed for an internally multistaged gas permeator based on the perfect mixing case. A problem of oxygen enrichment from air has been selected to illustrate the performance of the permeator. It has been shown that the effect of the number of permeation stages on oxygen enrichment is significant when the number of permeation stages is increased from one to two or three, and its effect reduces with a further increase in stage number. The results further reveal that no matter how many permeation stages are employed, the higher degree of separation is only achievable at lower values of overall stage cuts compared to the conventional single-stage permeator.
