Efficient gas separation with SEPURAN®

SEPURAN® Noble membranes for helium recovery


The thermal conductivity of Helium goes far beyond the other gases. Highly pure helium can be produced from natural gas or recovered from industrial processes.

In many applications, mixtures of Helium and e.g. air, nitrogen or argon are mostly used. By recovering the very valuable helium from these gas mixtures, very high cost savings can be realized. Recovery can take place by means of membranes. The very selective SEPURAN® Noble Membrane developed by Evonik, together with the clever membrane configuration of Evonik, combines high product gas purity with a high helium yield.

  • Highly selective membranes

  • Multiple membrane stage configurations based on customer-specific Needs for maximum and flexible recovery rates 

  • Existing production process can be economically and technically optimized

Typical fields of application
  • Optical fiber industry 

  • Medical devices, MRI Technology 

  • Leak detection 

  • Lifting gas 

  • Balloon filling 

  • Welding and metal work 

  • Electronics industry 

  • Oil and gas production 

  • Refrigerants

Evonik and Linde to cooperate

In Canada, Linde Engineering built the world's first plant to recover high-purity helium from N2-rich natural gas without the need for cryogenic technology using Evonik's membrane technology.

Separating noble gases

The hollow fiber membrane SEPURAN® Green has rapidly taken over the biogas market. The further developed version - SEPURAN® Noble - helps to recover the noble gas helium.
