Description:
The operation of membrane systems is based on the principle of differential velocity with which various gas mixture components permeate membrane substance. The driving force in the gas separation process is the difference in partial pressures on different membrane sides.
Each gas has its permeability to membrane. Due to permeability difference, when compressed air goes through the membrane units, as “fast gas”, oxygen permeates through membrane walls to outside, Nitrogen as “slow gas” is collected at outlet. Higher pressure leads to high permeability of each gas, at the meantime, the efficiency drops.
