Description:
The operation of membrane systems is based on the principle of differential velocity by which various components of a gas mixture permeate the membrane material. Gas separation is driven by the difference in partial pressures on each side of the membrane.
Each gas exhibits its own permeability through the membrane. Due to these permeability differences, when the gas mixture passes through the membrane modules using compressed air as the "fast gas", oxygen permeates through the membrane walls while nitrogen, designated as the "slow gas", is collected at the outlet. A higher pressure increases the permeability of individual gases; consequently, the efficiency decreases.
