Gas Separation Membrane

Separates CO2 from mixed gas efficiently with low energy to produce purified natural gas

Employed in natural gas purification, this gas separation membrane utilizes the membrane separation method of separating a specific gas from mixed gases by using differences in the permeation rates of the different gasses. Compared to other separation methods (chemical absorption, physical absorption, etc.), this method makes it possible to reduce production facility size and energy cost.

Gas purification using a separation membrane

The partial pressure difference across the membrane causes gas permeation while allowing only the target gas across.
