How it Works
Principle of Selective Permeation for Gas Seperation
The air in earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has very small amounts of lots of other inert gases too.
Gas separation membranes work according to the principle of selective permeation through the membrane surface. The permeation rate of each gas depends on its solubility in the membrane material and on the diffusion rate of the gas.
Gases with high solubility and small molecules such as oxygen, Co2 & water vapour pass through the membrane very quickly & permeate through the fibre walls. Less soluble gas such as Nitrogen with larger molecules takes more time to permeate the membrane, as a result enriched Nitrogen exits as product gas. In addition, different membrane materials separate differently. The driving force needed to separate gases is achieved by means of a partial pressure gradient.
