UBE CO2 Separator contains polyimide hollow fiber membranes. When compressed biogas flows into the hollow fibers, molecules with higher permeability rates for the membranes, such as CO2, H2O, O2, and H2S, pass through the membranes earlier than gases with lower permeability rates, such as CH4. The result of the differences in permeability rates is that highly purified CH4 is obtained after passing through UBE CO2 Separator.

UBE membranes have been operating in various fields for over 40 years. Thanks to our long history and with the aim of suiting your project, UBE offers various membrane types and sizes for CO2, N2 & H2 purifications, and further applications. These membranes play a fundamental role in applications such as biogas upgrading, food packaging, tire filling, analytical instruments, seal gas for plastic injection, among others.
The UBE membrane has a different permeation ratio for each molecule depending on 1.- molecule size and 2.- solubility to the membrane material, the permeation orders for our membrane are shown in the table below. We use the gap of permeation ratio of each molecule for gas separation.
UBE H2 separation modules have a “Shell” feed structure for use at high pressure, the compressed gas flows to the outer fiber, and the highly permeated gas such as H2, He, and CO2 preferentially permiate into the hollow of the fiber and is discharged from the permeation port.
UBE N2 Separator contains polyimide hollow fiber membranes. H2O, O2, CO2 permeate faster than N2. By flowing compressed air into the hollow fiber membrane, such highly permeable molecules go though the membrane first, and slowly permeable molecule, N2, then remains at the Product gas side. The product gas can be N2 purified up to 99.9% and very dried (low-dew point).
