Membranes for Helium Recovery

The principle of membrane separation of a gas mixture is based on the different penetration rates of its components through a polymeric membrane due to the differential partial pressures of the gas on either side of the membrane.

Membrane gas separation technology is widely used throughout the world to extract nitrogen from air, extract hydrogen from hydrogen-bearing gas mixtures, and extract carbon dioxide and water from natural gas.

Grasys Membrane Cartridges

• High selectivity
• High specific membrane surface area
• Wide pressure range (up to 13 MPa)
• Low pressure loss during separation
• Excellent chemical stability

Grasys Cartridge-Based Membrane Units

• Low capital and operating costs
• Easy to install and maintain
• Compact unit dimensions

Applications

The use of membrane technology for helium concentrate extraction enables significant reductions in capital and operating costs in the industrial development of large helium-bearing gas fields. Membrane technology is the only effective solution for the extraction of helium on remote fields. The use of membrane technology reduces the cost of cryogenic helium extraction units.
