Two-thirds of the total gas separation market is in the separation of nitrogen from air, and of hydrogen from ammonia purge gas.

Here are some applications examples in this market:

Air Separation

• Nitrogen from air separation.
• Separation of oxygen from air.

Hydrogen recovery

• For example, from a purge gas stream in ammonia synthesis.  Generally, hydrogen is recovered from waste process gases.

Natural gas

• Carbon dioxide removal (from natural gas, for example).
• Natural gas liquids removal.
• Natural gas dehydration.

Vapour / gas separation

Benefits that our materials provide for these applications

SULFONES and PVDF membrane materials offer:

• High permeability to specific gas.
• High selectivity to specific gas.
• Ability to form stable and thin structures that can be packaged into high surface area modules.

In this Gas application, membranes offer:

• Cheaper operation economics
• More tolerance towards lower gas purity
