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.

Ion-Exchange Membrane

High-quality, mass-producible ion-exchange
membrane based on proprietary technology
that allows selective permeation of ions

Ion-exchange membrane selectively allows ions in solvents to pass through and is widely used in various applications, such as softening hard water; producing ultrapure water; extracting salt from seawater; and desalinating brackish water, seawater, industrial wastewater, and materials used in food processing. The ion-exchange membrane process exhibits superior maintenance and cost benefits compared to the ion-exchange resin process, which requires periodic renewal using salt and replacing resin.

New development in ion-exchange membrane technology

Verification tests for harvesting energy from differences in salt concentration between sea water and fresh water (Blue Energy) are currently underway in the Netherlands with the goal of constructing a power plant to supply 200 MW of electricity for 300,000 households by 2020. Fujifilm is participating in this project by providing ion-exchange membranes.
