Generally, all gases can permeate through polymer membranes. The process involves gas molecules first being adsorbed and dissolved on the high-pressure side of the membrane. Then, they diffuse through the membrane due to the concentration gradient and finally desorb from the low-pressure side. As a result, small molecules and highly polar molecules (such as water vapor, oxygen, and carbon dioxide) permeate faster and are enriched on the permeate side of the membrane; while large molecules and less polar molecules (such as nitrogen and argon) permeate slower and are retained and enriched on the retention side of the membrane, thus achieving the separation of the mixed gases.
Membrane separation utilizes the different permeation rates of various gases on a polymer membrane to achieve gas separation. The driving force for separation is the partial pressure difference between the gases on both sides of the membrane. Therefore, membrane gas separation does not involve phase change and does not require regeneration. It has advantages such as simple equipment and low operating and maintenance costs.
A membrane separator (module) consists of thousands of hollow fiber separation membranes assembled in a shell. Its structure is similar to a shell and tube heat exchanger. It can provide the largest separation membrane surface area in the smallest space. Therefore, membrane separation systems have the advantages of small footprint, light weight and high separation efficiency.
