SEPURAN® Noble Membranes for efficient helium recovery

Evonik's SEPURAN® Noble membrane has been especially developed for helium recovery and purification enabling highly pure helium to be efficiently produced even when inlet concentrations of helium are very low.

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.
