Separating methane and carbon dioxide to become more ...

To make natural gas and biogas suitable for use, the methane has to be separated from the CO₂. This involves the use of membranes: filters that stop the methane and let the CO₂ pass through. Researchers at KU Leuven have developed a new membrane that makes the separation process much more ...

Carbon Dioxide, CO 2 Separation - Generon

Carbon Dioxide, CO 2, is commonly found in natural gas.In order to meet pipeline specifications or other application specific requirements, CO 2 separation is necessary. In addition, there may also be H 2 S and H 2 O present that needs to be removed. CO 2 separation membranes have been widely used for CO 2 removal applications and come with the added benefit of removing H 2 S and H 2 O as well.
